    The Swedish Radiation Protection Authority has investigated the status of radiation protection in connection with percutaneous coronary interventions (PCI) in Swedish hospitals. A questionnaire was send to hospitals concerning basic radiation protection procedures stated in the Swedish regulations. A questionnaire was also sent out to radiologists and cardiologists and the answers from those who performed interventions were analysed. The study indicates a strong need for improving radiation protection, as an example many hospitals could not present any documents describing methods or radiation protection procedures in connection with these interventions. Moreover, the radiation dose to hands and eyes of the personnel is rarely measured and the fluoroscopic time used for the interventions is not properly analysed. SSI is convinced that many hospitals need to improve radiation protection to meet the demands of the regulations. This could be accomplished by more efficient organized radiation protection work in the hospitals.

    To assess the role of percutaneous cholecystostomy as a therapeutic maneuver in patients critically ill with acute cholecystitis in community hospitals. Eighteen patients, 11 with suspected acute calculous cholecystits and seven with acute acalulous cholecystitis underwent emergency percutaneous cholecystostomy. All demonstrated a variety of high risk factors for cholecystectomy:liver cirrhosis(n=3D2), diabetes mellitus(n=3D3), cardiac disease(n=3D3), underlying malignancy(n=3D2), pulmonary dysfunction(n=3D1), septic cholangitis(n=3D5), and old age(n=3D2). All percutaneous cholecystostomies were performed with ultrasound guidance and preferably using the transhepatic route. All procedures but one were successful, and most cholecystostomies were performed within 5-20 minutes. Technical problems were as follows: guide-wire buckling during catheter insertion(n=3D2) and procedure failure(n=3D1). The only major problem was a case of localized bile peritonitis due to procedural failure, but a few minor complications were encountered:catheter dislodgment(n=3D3), and significant abdominal pain during the procedure(2). After successful cholecystostomy, a dramatic improvement in clinical condition was observed in 16 of 17 patients(94%) within 48 hours. Ten of 16 patients who responded to percutaneous cholecystostomy underwent elective cholecystectomy after the improvement of clinical symptoms, and the remaining six patients improved without other gallbladder interventions. Percutaneous cholecystostomy is not only an effective procedure for acute cholecystitis, but also has a definite role in the management of these high-risk patients in community hospitals.=20

    Full Text Available Objectives: Percutaneous injuries (PCIs remain a common incident among healthcare workers (HCWs despite the introductionof safety programs. The aim of this study was to assess the PCIs, required precautions, and applications after the injuries among healthcare workers in a small general hospital.Materials and methods: We assessed the occurrence of PCIs at a General Hospital (EGH from January 2007 to November2010. During this period, all injury cases among HCWs were reported to the Infection Control Committee (ICC using percutaneous injury notification form. The injury notification forms were evaluated retrospectively.Results: Totally 275 health personnel were working in our hospital, 36 healthy workers have been exposed to PCIs during this period. The incidence of PCIs was 2,9/10000 in 2007, 3,1/10000 in 2008, 3,8/10000 in 2009 and 3,9/10000 patient-days in 2010. Injured staff were recorded as, 16 nurses (44%, 12 cleaning staffs (34%, and eight (22% doctors. The device leading to damage was most frequently the needle-channel. Ten sources (27% were detected positive for hepatitis B virus (HBV, four (11% for hepatitis C virus (HCV, and two (5% for Crimean-Congo hemorrhagic fever virus (CCHFV. No case of seroconversion has been recognized for any of the above mentioned infections.Conclusions: Percutaneous injuries remain to occur among HCWs. Since some the sources were infected, the health personnel are endangered for infections due to PCIs. The health personnel should presume that all patients are infected,and thus should work following universal precautions to avoid complications about the PCIs. J Microbiol Infect Dis 2011;1(1:26-30.

    All percutaneous tracheostomies performed in the general intensive care unit (ICU), Hospital Sultanah Aminah, Johor Bahru, Malaysia, from July 1999 to June 2002 were studied. The tracheostomies were performed as an elective bedside technique in the ICU. A total of 352 percutaneous tracheostomies were performed. Eighty-eight percent of the tracheostomies were completed within 15 minutes. The most common complication was bleeding which occurred in 52 patients (14.7%). The rest of the complications encountered were:- transient hypoxia twelve (3.4%), inability/ difficulty to insert tracheostomy tube eight (2.3%), false passage four (1.1%), transient hypotension two (0.6%), pneumothorax two (0.6%), peristomal infection two (0.6%), subcutaneous emphysema one (0.3%), cuff rupture one (0.3%), oesophageal cannulation one (0.3%), and granuloma formation one (0.3%). Conversion to conventional tracheostomies were performed on 7 patients (2%). There was one unfortunate death related to percutaneous tracheostomy. In conclusion, percutaneous dilational tracheostomy can be used safely to manage the airway of critically ill patients.

    Percutaneous closure of patent foramen ovale/atrial septal defect (PFO/ASD) is an increasingly common procedure perceived as having minimal risk. There are no population-based estimates of in-hospital adverse event rates of percutaneous PFO/ASD closure. We used nationally representative data from the 2001-2005 Nationwide Inpatient Sample to identify patients >or-=20 years old admitted to an acute care hospital with an International Classification of Diseases, Ninth Revision code designating percutaneous PFO/ASD closure on the first or second hospital day. Variables analyzed included age, sex, number of comorbidities, year, same-day use of intracardiac or other echocardiography, same-day left heart catheterization, hospital size and teaching status, PFO/ASD procedural volume, and coronary intervention volume. Outcomes of interest included length of stay, charges, and adverse events. The study included 2,555 (weighted to United States population: 12,544 +/- 1,987) PFO/ASD closure procedures. Mean age was 52.0 +/- 0.4 years, and 57.3% +/- 1.0% were women. Annual hospital volume averaged 40.8 +/- 7.7 procedures (range, 1-114). Overall, 8.2 +/- 0.8% of admissions involved an adverse event. Older patients and those with comorbidities were more likely to sustain adverse events. Use of intracardiac echocardiography was associated with fewer adverse events. The risk of adverse events was inversely proportional to annual hospital volume (odds ratio [OR] 0.91, 95% confidence interval [CI] 0.86-0.96, per 10 procedures), even after limiting the analysis to hospitals performing >or=10 procedures annually (OR 0.91, 95% CI 0.85-0.98). Adverse events were more frequent at hospitals in the lowest volume quintile as compared with the highest volume quintile (13.3% vs 5.4%, OR 2.42, 95% CI 1.55-3.78). The risk of adverse events of percutaneous PFO/ASD closure is inversely correlated with hospital volume. This relationship applies even to hospitals meeting the current guidelines

    Percutaneous transhepatic biliary drainage was successfully made 20 times on 17 patients of obstructive jaundice for recent 1 year since June 1981 at Department of Radiology in Seoul National University Hospital. The causes of obstructive jaundice was CBD Ca in 13 cases, metastasis in 2 cases, pancreatic cancer in 1 case and CBD stone in 1 case. Percutaneous transhepatic biliary drainage is a relatively ease, safe and effective method which can be done after PTC by radiologist. It is expected that percutaneous transhepatic biliary drainage should be done as an essential procedure for transient permanent palliation of obstructive jaundice

    Public reporting of percutaneous coronary intervention (PCI) outcomes may create disincentives for physicians to provide care for critically ill patients, particularly at institutions with worse clinical outcomes. We thus sought to evaluate the procedural management and in-hospital outcomes of patients treated for acute myocardial infarction before and after a hospital had been publicly identified as a negative outlier. Using state reports, we identified hospitals that were recognized as negative PCI outliers in 2 states (Massachusetts and New York) from 2002 to 2012. State hospitalization files were used to identify all patients with an acute myocardial infarction within these states. Procedural management and in-hospital outcomes were compared among patients treated at outlier hospitals before and after public report of outlier status. Patients at nonoutlier institutions were used to control for temporal trends. Among 86 hospitals, 31 were reported as outliers for excess mortality. Outlier facilities were larger, treating more patients with acute myocardial infarction and performing more PCIs than nonoutlier hospitals ( P fashion (interaction P =0.50) after public report of outlier status. The likelihood of in-hospital mortality decreased at outlier institutions (RR, 0.83; 95% CI, 0.81-0.85) after public report, and to a lesser degree at nonoutlier institutions (RR, 0.90; 95% CI, 0.87-0.92; interaction P <0.001). Among patients that underwent PCI, in-hospital mortality decreased at outlier institutions after public recognition of outlier status in comparison with prior (RR, 0.72; 9% CI, 0.66-0.79), a decline that exceeded the reduction at nonoutlier institutions (RR, 0.87; 95% CI, 0.80-0.96; interaction P <0.001). Large hospitals with higher clinical volume are more likely to be designated as negative outliers. The rates of percutaneous revascularization increased similarly at outlier and nonoutlier institutions after report of outlier status. After outlier

    Full Text Available Percutaneous vertebroplasty is a minimal invasive procedure that is applied for the treatment of osteoporotic vertebral fractures. During vertebroplasty, the leakage of bone cement outside the vertebral body leads to pulmonary cement embolism, which is a serious complication of this procedure. Here we report a 48-year-old man who was admitted to our hospital with dyspnea after percutaneous vertebroplasty and diagnosed as pulmonary cement embolism.

    The aim of this study was to examine temporal trends and provincial variations in reperfusion strategies and in-hospital mortality among patients presenting with ST-segment elevation myocardial infarction (STEMI) at hospitals in Canada capable of performing percutaneous coronary intervention (PCI). We included patients aged ≥ 20 years who were hospitalized between fiscal years 2009 and 2013 in all provinces except Quebec. We categorized patients as receiving fibrinolysis (lysis), primary PCI (pPCI), or no reperfusion. Patients undergoing lysis were further categorized as (1) lysis + PCI ≤ 90 minutes, (2) lysis + PCI > 90 minutes, and (3) lysis only. Patients undergoing pPCI were further categorized as (1) pPCI ≤ 90 minutes and (2) pPCI > 90 minutes. We used logistic regression to examine the baseline-adjusted association between reperfusion strategy and in-hospital mortality. Among 44,650 STEMI episodes in 44,373 patients, 66.3% received pPCI (annual increase of 7.8%; P 90 minutes (adjusted odds ratio of 0.42; 95% confidence interval, 0.32-0.55 compared with pPCI ≤ 90 minutes). The use of pPCI in STEMI has increased significantly in Canada; however, significant interprovincial variation remains. Changes in reperfusion strategies do not appear to have had an impact on in-hospital mortality rates. Patients who underwent lysis followed by PCI in a systematic fashion had the lowest mortality.

    This study sought to develop a percutaneous coronary intervention (PCI) risk score for in-hospital/30-day mortality. Risk scores are simplified linear scores that provide clinicians with quick estimates of patients' short-term mortality rates for informed consent and to determine the appropriate intervention. Earlier PCI risk scores were based on in-hospital mortality. However, for PCI, a substantial percentage of patients die within 30 days of the procedure after discharge. New York's Percutaneous Coronary Interventions Reporting System was used to develop an in-hospital/30-day logistic regression model for patients undergoing PCI in 2010, and this model was converted into a simple linear risk score that estimates mortality rates. The score was validated by applying it to 2009 New York PCI data. Subsequent analyses evaluated the ability of the score to predict complications and length of stay. A total of 54,223 patients were used to develop the risk score. There are 11 risk factors that make up the score, with risk factor scores ranging from 1 to 9, and the highest total score is 34. The score was validated based on patients undergoing PCI in the previous year, and accurately predicted mortality for all patients as well as patients who recently suffered a myocardial infarction (MI). The PCI risk score developed here enables clinicians to estimate in-hospital/30-day mortality very quickly and quite accurately. It accurately predicts mortality for patients undergoing PCI in the previous year and for MI patients, and is also moderately related to perioperative complications and length of stay.

    Hydatic disease caused by Echinococcus granulosus is an endemic disease and an important public health problem in some countries of the world. The results of surgical treatment are associated with a high rate of mortality, morbidity, postoperative recurrence and a long period of hospital stay and the medical treatment results are still controversial. Although the percutaneous aspiration and treatment of liver hydatid cysts were considered to be contraindicated due to risks of anaphylactic shock and dissemination of clear-crystal fluid into the abdomen, several reports of successful percutaneous treatment of liver hydatid cysts have been published in the literature. Today, percutaneous treatment of liver hydatid cysts is the most effective and reliable treatment procedure in the selected cases. In this review, indications, contraindications, method and techniques, healing criteria, complications, results and importance of the percutaneous treatment of liver hydatid cysts are discussed.

    A retrospective review of patients being treated by percutaneous endoscopic gastrostomy (PEG) at Auckland Hospital from 1993-4 was undertaken in order to determine patient characteristics, clinical outcome and to compare these results with published series. The case notes of all patients having PEGs performed in the Auckland Hospital gastroenterology unit during the defined period were reviewed. Demographic details, indications, morbidity and mortality data were obtained. Data were supplemented with information obtained from the general practitioner. Fifty procedures (18 in 1993, 32 in 1994) were performed on 41 patients (29 male 12 female), with a mean age of 61 years. Neurological disorders represented the most common clinical indication (25) followed by head and neck malignancy (9). Three patients (7) died within 30 days of the procedure and 13 (32) had early complications (less than 30 days) with four (10) having late complications. Significant pain requiring narcotics occurred in 18. Results were in general comparable to published series apart from a higher early complication rate (32% vs 16%). Pain may be significant post procedure and should be anticipated. The increasing use of this procedure in our hospital reflects its acceptability to patients, relatives and staff as a means of providing nutritional support to the patient with disorders of swallowing.

    PurposeCystic echinococcosis (CE) in the spleen is a rare disease even in endemic regions. The aim of this study was to examine the efficacy of percutaneous treatment for splenic CE.Materials and MethodsTwelve patients (four men, eight women) with splenic CE were included in this study. For percutaneous treatment, CE1 and CE3A splenic hydatid cysts were treated with either the PAIR (puncture, aspiration, injection, respiration) technique or the catheterization technique.ResultsEight of the hydatid cysts were treated with the PAIR technique and four were treated with catheterization. The volume of all cysts decreased significantly during the follow-up period. No complication occurred in seven of 12 patients. Abscess developed in four patients. Two patients underwent splenectomy due to cavity infection developed after percutaneous treatment, while the spleen was preserved in 10 of 12 patients. Total hospital stay was between 1 and 18 days. Hospital stay was longer and the rate of infection was higher in the catheterization group. Follow-up period was 5–117 months (mean, 44.8 months), with no recurrence observed.ConclusionThe advantages of the percutaneous treatment are its minimal invasive nature, short hospitalization duration, and its ability to preserve splenic tissue and function. As the catheterization technique is associated with higher abscess risk, we suggest that the PAIR procedure should be the first percutaneous treatment option for splenic CE.

METHODS: From August 1996 to April 2001, we studied 86 patients with carotid arterial obliterative lesions > 70% who were treated with percutaneous stent placement in the carotid arteries. We assessed the rate of success of the implantation and of the procedure, the types of stents used, mortality rate, and neurological complications. RESULTS: Successful implantation was obtained in 98.9% of the cases, and the procedure was successful in 91.8%. The Wallstent was the most frequently used stent (73 patients - 77%. Cerebral strokes occurred as follows: 3 (3.2% transient ischemic attacks, 1 (1.1% minor stroke, and 3 (3.1% major strokes. One (1.1% patient died during hospitalization. CONCLUSION: The high rate of success of stent implantation (98.9% in addition to the low rate of cerebral stroke/death (4.2% showed the efficiency and safety of percutaneous stent placement in carotid arteries.

    Full Text Available Abstract Background Percutaneous exposure incidents facilitate transmission of bloodborne pathogens such as human immunodeficiency virus (HIV, hepatitis C virus (HCV and hepatitis B virus (HBV. This study was conducted to identify the circumstances and equipment related to percutaneous injuries among dental professionals. Methods We used workers' compensation claims submitted to the Department of Labor and Industries State Fund during a 7-year period (1995 through 2001 in Washington State for this study. We used the statement submitted by the injured worker on the workers' compensation claim form to determine the circumstances surrounding the injury including the type of activity and device involved. Results Of a total of 4,695 accepted State Fund percutaneous injury claims by health care workers (HCWs, 924 (20% were submitted by dental professionals. Out of 924 percutaneous injuries reported by dental professionals 894 (97% were among dental health care workers in non-hospital settings, including dentists (66, 7%, dental hygienists (61, 18% and dental assistants (667, 75%. The majority of those reporting were females (638, 71%. Most (781, 87% of the injuries involved syringes, dental instruments (77, 9%, and suture needles (23%. A large proportion (90% of injuries occurred in offices and clinics of dentists, while remainder occurred in offices of clinics and of doctors of medicine (9%, and a few in specialty outpatient facilities (1%. Of the 894 dental health care workers with percutaneous injuries, there was evidence of HBV in 6 persons, HCV in 30 persons, HIV in 3 persons and both HBV and HVC (n = 2 exposure. Conclusion Out of hospital percutaneous injuries are a substantial risk to dental health professionals in Washington State. Improved work practices and safer devices are needed to address this risk.

    The authors report the personal techniques and the results of CT-guided percutaneous drainage of postoperative abdominal fluid collections. CT-guided percutaneous drainage offers many advantages over surgery: it is less invasive, can be repeated and requires no anesthesia, there are not surgery-related risks and lower morbidity and mortality rates. Moreover, subsequent hospitalization is shorter and costs are consequently reduced. The authors conclude that CT-guided percutaneous drainage is the method of choice in the treatment of postoperative abdominal fluid collections [it

    1989-01-01

    During a four year period, ending May 1987, 154 cases of symptomatic staghorn calculi have been treated by percutaneous nephrolithotomy. Of these patients,86% were discharged completely stone free with the remainder having fragments less than 5 mm in greatest diameter. More than one operative procedure during the same hospitalizations was required in 24% of patients and multiple percutaneous tracts were established in excess of 73% of them. Significant complications occurred in 16% of patients and there was one death. Most complications can be generally by minimized by careful approach and manageable by interventional radiological means. The management of patients with staghorn calculi requires a comprehensive understanding of the renal anatomy, selection of appropriate percutaneous nephrostomy tract sites, and radiologic-urologic expertise needed to remove the large stone mass. The advent of extracorporeal shock wave lithotripsy will not abolish the need for nephrolithotomy, particularly complex stones such as staghorn calculi

    To evaluate the technical feasibility and clinical efficacy of percutaneous common bile duct stone extraction via cystic duct after percutaneous cholecystostomy. Twenty-five consecutive patients with choledocholithiasis underwent percutaneous stone extraction under conscious sedation. The stones were extracted through the 12-Fr sheath using Wittich nitinol stone basket under fluoroscopic guidance via cystic duct after percutaneous trnas-hepatic cholecystostomy. Common bile duct stones were successfully removed in 22 of the 25 patients (88%) by this new technique. The causes of failure in three patients were bile leakage, hematoma of the gallbladder and failure of cystic duct cannulation. Cystic duct injury during this procedure did not occur and there was no post-procedure mortality. The mean period of indwelling catheter was 8.7±4.6 days and the mean duration of hospitalization was 13.4±5.9 days. Percutaneous commmon bile duct stone extraction via the cystic duct through percutaneous cholecystostomy route is effective and feasible for treating choledocholithiasis.

    The purpose of this article is to review PTCA, percutaneous transluminal coronary angioplasty, which can be considered to be a truly revolutionary and fairly simple invasive form of intervention to atherosclerotic obstruction. The 'epidemic' of IHD, ischaemic heart disease, in the Republic of South Africa calls for the employment of this technique, which has already been carried out in a few teaching hospitals in this country. Very recently, modified balloon dilatation catheters have been used percutaneously in the non-operative transluminal correction of congenital coarctation of the aorta in infants and children, congenital pulmonary value stenosis, and hypoplasia and stenosis of the pulmonary arteries. It has also been employed for PTCA and for the simultaneous occlusion of coronary-bronchial artery anastomosis using a detachable balloon. The isotopes thallium 201 and technetium 99 were also used in scintiscanning

    Pain is one of the most common and feared complication of percutaneous liver biopsy under local anaesthesia using sonographic guidance. This observational study was set to judge the intensity of pain felt by adult patients presenting for percutaneous liver biopsy with known/suspected underlying hepatic pathology. Methods: This observational cross sectional study which was piloted on 10% of the original sample size was conducted at Aga Khan University Hospital, Karachi. Study population was the adult patients coming for percutaneous liver biopsy at the Department of Radiology. Descriptive statistics were run, data was checked for normality. Means and Standard deviations were done for continuous variables and where data was skewed, median with inter quartile range was computed. Later data was clumped in categories, frequency and percentages were reported for categorical variables. Graphical representation of data was done. Results: A total of 50 patients were recruited. Minimum pain reported on visual analogue scale (VAS) was 0 and maximum as 4.30% of patients rated 3 and similarly 30% of the people rated 4 on the VAS. Mean pain experienced was 2.7 ± 1.11 and a median of 3 on VAS. This indicates that a minority of patients in our survey had a complaint of mild pain during the procedure. Conclusions: Percutaneous liver biopsy is a very safe procedure and minimal pain was felt by a minority of patients whereas the rest showed satisfaction from the procedure with no post procedural complaints.

    The risk of major complications, especially hemorrhage, is significantly elevated during surgery in hypertensive patients. To determine whether percutaneous nephrolithotomy (PCNL) can be safely performed in the hypertensive patients using different sized instruments. We reviewed the records of 602 patients undergoing PCNL at our institution and identified 53 who were on antihypertensive therapy at the time of surgery. Patients were categorized into three groups according to size of devices used in surgery : those 24 F percutaneous tract with 22 F nephroscope (Group 1, n = 12 [22.7%]; 26 F percutaneous tract with 24 F nephroscope (Group 2, n = 19 [35.8%]) and 30 F percutaneous tract with 26 F nephroscope (Group 3, n = 22 [41.5%]). We compared the groups with regard to baseline characteristics, intraoperative parameters, stone-free and complication rates, and the length of hospitalization. There were no differences between the three groups in age, gender, weight and stone laterality. Fluoroscopy time, access to the collecting system and mean operative time for per cm2 stone did not differ between the groups. Hemoglobin decrease, postoperative hospital stay and blood transfusion rate was higher in group 3. Stones were completely cleared in 83.3%, 84.2% and 81.3% of patients, which increased to 91.6%, 89.5%, and 90.1% with adjunctive therapy in the group 1,2 and 3, respectively. PCNL with smaller devices is a safe and effective method in hypertensive patients. It has significantly a shorter hospital stay and less bleeding rates compared to classical PCNL.

    In recent years, percutaneous tracheostomy has become a routine practice in many hospitals. In the early publications, most authors considered adverse conditions such as short, fat neck or obesity as relative contraindications whereas cervical injury, coagulopathy, and emergency were regarded as absolute contraindications. More recently, several reports demonstrated the feasibility of percutaneous tracheostomy in patients with some of these contraindications. The aim of this study is to determine the safety and efficacy of percutaneous tracheostomy in conditions commonly referred to as contraindications. Between June 2000 and July 2001, 157 consecutive percutaneous tracheostomy procedures were performed on 154 critically ill adult patients in the general intensive care unit of a major tertiary care facility. The Griggs technique and Portex set were used at the bedside. All procedures were performed by staff thoracic surgeons and anesthesiologists experienced with the technique. Anatomical conditions, presence of coagulopathy and anti-coagulation therapy, demographics, and complication rates were recorded. Five of 157 procedures (154 patients owing to three repeat tracheostomies) had complications. In patients with normal anatomical conditions and coagulation profiles, there was one case of bleeding (50 cc to 120 cc) and one case of mild cellulitis around the stoma. In patients with adverse conditions, there was one case of bleeding (50 cc to 120 cc) and two cases of minor bleeding (< 50 cc). Patients with adverse conditions had a low complication rate similar to patients with normal conditions. For this reason, we believe that percutaneous tracheostomy is indicated in patients with short, fat neck; inability to perform neck extension; enlarged isthmus of thyroid; previous tracheostomy; or coagulopathy and anti-coagulation therapy.

    The role of circulatory support in the post-cardiac arrest period remains controversial. Our objective was to investigate the association between treatment with a percutaneous hemodynamic support device and outcome after admission for cardiac arrest. We performed a retrospective study of adult patients with admission diagnosis of cardiac arrest or ventricular fibrillation (VF) from the Michigan Inpatient Database, treated between July 1, 2010, and June 30, 2013. Patient demographics, clinical characteristics, treatments, and disposition were electronically abstracted based on ICD-9 codes at the hospital level. Mixed-effects logistic regression models were fit to test the effect of percutaneous hemodynamic support device defined as either percutaneous left ventricular assist device (pLVAD) or intra-aortic balloon pump (IABP) on survival. These models controlled for age, sex, VF, myocardial infarction (MI), and cardiogenic shock with hospital modeled as a random effect. A total of 103 hospitals contributed 4393 patients for analysis, predominately male (58.8%) with a mean age of 64.1years (SD 15.5). On univariate analysis, younger age, male sex, VF as the initial rhythm, acute MI, percutaneous coronary intervention, percutaneous hemodynamic support device, and absence of cardiogenic shock were associated with survival to discharge (each p<0.001). Mixed-effects logistic regressions revealed use of percutaneous hemodynamic support device was significantly associated with survival among all patients (OR 1.8 (1.28-2.54)), and especially in those with acute MI (OR 1.95 (1.31-2.93)) or cardiogenic shock (OR 1.96 (1.29-2.98)). Treatment with percutaneous hemodynamic support device in the post-arrest period may provide left ventricular support and improve outcome. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available   Introduction: This study aimed to compare primary percutaneous coronary intervention (PPCI versus reteplase in terms of clinical and para-clinical outcomes; as well as cost-effectiveness in patients with ST-segment-elevation myocardial infarction (STEMI.Primary percutaneous coronary intervention is the method of choice in all patients especially those at higher risks. But an on-site professional team in a 24/7 facilitated system is a difficult goal to achieve in many areas and countries, therefore the cost-effectiveness of these two treatment strategies (PPCI and reteplase needs to be discussed.Methods: This prospective cohort study included 220 patients presented with STEMI who were admitted to a university hospital between January 2014 to July 2016. Patients were divided into two groups of 120, either receiving reteplase or PPCI. Clinical outcomes were considered duration of hospital stay and MACE (Major Advanced Cardiovascular Events including death, cerebrovascular accident, need for repeat revascularization, and major bleeding. LVEF (Left ventricular ejection fraction was considered as a para-clinical outcome. The outcomes and total hospital cost were compared between two treatment groups.Results: Demographic characteristics between two groups of PPCI or reteplase didn’t show any significant differences. But in para-clinical outcomes, patients in PPCI group showed higher LVEF, compared with reteplase group (45.9 ± 11.5% versus 42.0 ± 11.8%; P = 0.02. Complication rates were similar in both groups but repeat revascularization or coronary artery bypass surgery was more prevalent in those who received thrombolytic therapy (P < 0.05.

    Endoscopic drainage of pancreatic acute and chronic pseudocysts and pancreatic necrosectomy have been shown to be beneficial for critically ill patients, with complete endoscopic resolution rates of around 80%. Our purpose was to describe an improved endoscopic technique used to treat pancreatic necrosis. Case report. University hospital. Two patients with large retroperitoneal necroses were treated with percutaneous transgastric retroperitoneal flushing tubes and a percutaneous transgastric jejunal feeding tube by standard percutaneous endoscopic gastrostomy access in addition to endoscopic necrosectomy. Intensive percutaneous transgastric flushing in combination with percutaneous normocaloric enteral nutrition and repeated endoscopic necrosectomy led to excellent outcomes in both patients. Small number of patients. The "double percutaneous endoscopic gastrostomy" approach for simultaneous transgastric drainage and normocaloric enteral nutrition in severe cases of pancreatic necroses is safe and effective. It could be a promising improvement to endoscopic transgastric treatment options in necrotizing pancreatitis.

    Transcatheter aortic valve replacement is now the standard of care for severe symptomatic aortic stenosis patients who are at high-surgical risk. Percutaneous approach without a surgical cut down has been increasingly adapted by some centers in USA. Percutaneous approach seems to be associated with shorter hospital stay, similar short and late vascular complications, less disabling stroke, similar mortality as well as significantly less hospital cost. However, this technique also requires operators to be able to manage any vascular complications using advanced endovascular interventions to achieve complete hemostasis. © 2018 Wiley Periodicals, Inc.

    Full Text Available Background: Lumbar disc herniation is a major cause of back pain and sciatica. The surgical management of lumbar disc prolapse has evolved from exploratory laminectomy to percutaneous endoscopic discectomy. Percutaneous endoscopic discectomy is the least invasive procedure for lumbar disc prolapse. The aim of this study was to analyze the clinical outcome, quality of life, neurologic function, and complications. Materials and Methods: One hundred patients with lumbar disc prolapse who were treated with percutaneous endoscopic discectomy from May 2012 to January 2014 were included in this retrospective study. Clinical followup was done at 1 month, 3 months, 6 months, 1 year, and at yearly interval thereafter. The outcome was assessed using modified Macnab′s criteria, visual analog scale, and Oswestry Disability Index. Results: The mean followup period was 2 years (range 18 months - 3 years. Transforaminal approach was used in 84 patients, interlaminar approach in seven patients, and combined approach in nine patients. An excellent outcome was noted in ninety patients, good outcome in six patients, fair result in two patients, and poor result in two patients. Minor complications were seen in three patients, and two patients had recurrent disc prolapse. Mean hospital stay was 1.6 days. Conclusions: Percutaneous endoscopic lumbar discectomy is a safe and effective procedure in lumbar disc prolapse. It has the advantage that it can be performed on a day care basis under local anesthesia with shorter length of hospitalization and early return to work thus improving the quality of life earlier. The low complication rate makes it the future of disc surgery. Transforaminal approach alone is sufficient in majority of cases, although 16% of cases required either percutaneous interlaminar approach or combined approach. The procedure definitely has a learning curve, but it is acceptable with adequate preparations.

    Solid-organ transplant recipients may require percutaneous dilational tracheotomy because of prolonged mechanical ventilation or airway issues, but data regarding its safety and effectiveness in solid-organ transplant recipients are scarce. Here, we evaluated the safety, effectiveness, and benefits in terms of lung mechanics, complications, and patient comfort of percutaneous dilational tracheotomy in solid-organ transplant recipients. Medical records from 31 solid-organ transplant recipients (median age of 41.0 years [interquartile range, 18.0-53.0 y]) who underwent percutaneous dilational tracheotomy at our hospital between January 2010 and March 2015 were analyzed, including primary diagnosis, comorbidities, duration of orotracheal intubation and mechanical ventilation, length of intensive care unit and hospital stays, the time interval between transplant to percutaneous dilational tracheotomy, Acute Physiology and Chronic Health Evaluation II score, tracheotomy-related complications, and pulmonary compliance and ratio of partial pressure of arterial oxygen to fraction of inspired oxygen. The median Acute Physiology and Chronic Health Evaluation II score on admission was 24.0 (interquartile range, 18.0-29.0). The median interval from transplant to percutaneous dilational tracheotomy was 105.5 days (interquartile range, 13.0-2165.0 d). The only major complication noted was left-sided pneumothorax in 1 patient. There were no significant differences in ratio of partial pressure of arterial oxygen to fraction of inspired oxygen before and after procedure (170.0 [interquartile range, 102.2-302.0] vs 210.0 [interquartile range, 178.5-345.5]; P = .052). However, pulmonary compliance results preprocedure and postprocedure were significantly different (0.020 L/cm H2O [interquartile range, 0.015-0.030 L/cm H2O] vs 0.030 L/cm H2O [interquartile range, 0.020-0.041 L/cm H2O); P = .001]).

    Percutaneous retrograde gastrostomy has a high success rate, low morbidity, and can be performed under different levels of sedation or local anesthesia in children. Despite its favourable safety profile, major complications can occur. Few studies have examined peritonitis following percutaneous retrograde gastrostomy in children. To identify potential risk factors and variables influencing the development and early diagnosis of peritonitis following percutaneous retrograde gastrostomy. We conducted a retrospective case-control study of children who developed peritonitis within 7 days of percutaneous retrograde gastrostomy between 2003 and 2012. From the 1,504 patients who underwent percutaneous retrograde gastrostomy, patients who developed peritonitis (group 1) were matched by closest date of procedure to those without peritonitis (group 2). Peritonitis was defined according to recognized clinical criteria. Demographic, clinical, procedural, management and outcomes data were collected. Thirty-eight of 1,504 children (2.5%; 95% confidence interval, 1.8-3.5) who underwent percutaneous retrograde gastrostomy developed peritonitis ≤7 days post procedure (group 1). Fever (89%), irritability (63%) and abdominal pain (55%) occurred on presentation of peritonitis. Group 1 patients were all treated with antibiotics; 41% underwent additional interventions: tube readjustments (8%), aspiration of pneumoperitoneum (23%), laparotomy (10%) and intensive care unit admission (10%). In group 1, enteral feeds started on average 3 days later and patients were discharged 5 days later than patients in group 2. There were two deaths not directly related to peritonitis. Neither age, gender, weight, underlying diagnoses nor operator was identified as a risk factor. Peritonitis following percutaneous retrograde gastrostomy in children occurs in approximately 2.5% of cases. No risk factors for its development were identified.

    Current comparative outcomes among black and white patients treated with percutaneous coronary intervention (PCI) in the Veterans Affairs (VA) health system are not known. To compare outcomes between black and white patients undergoing PCI in the VA health system. This study compared black and white patients who underwent PCI between October 1, 2007, and September 30, 2013, at 63 VA hospitals using data recorded in the VA Clinical Assessment, Reporting, and Tracking System for Cardiac Catheterization Laboratories (CART-CL) program. A generalized linear mixed model with a random intercept for site assessed the relative difference in odds of outcomes between black and white patients. The setting was integrated institutionalized hospital care. Excluded were all patients of other races or those with multiple listed races and those with missing data regarding race or the diagnostic cardiac catheterization. The dates of analysis were January 7, 2016, to April 17, 2017. Percutaneous coronary intervention at a VA hospital. The primary outcome was 1-year mortality. Secondary outcomes were 30-day all-cause readmission rates, 30-day acute kidney injury, 30-day blood transfusion, and 1-year readmission rates for myocardial infarction. In addition, variations in procedural and postprocedural care were examined, including the use of intravascular ultrasound, optical coherence tomography, fractional flow reserve measurements, bare-metal stents, postprocedural medications, and radial access. A total of 42 391 patients (13.3% black and 98.4% male; mean [SD] age, 65.2 [9.1] years) satisfied the inclusion and exclusion criteria. In unadjusted analyses, black patients had higher rates of 1-year mortality (7.1% vs 5.9%, P < .001) as well as secondary outcomes of 30-day acute kidney injury (20.8% vs 13.8%, P < .001), 30-day blood transfusion (3.4% vs 2.7%, P < .01), and 1-year readmission rates for myocardial infarction (3.3% vs 2.7%, P = .01) compared with white

    Objective The aim of this study was to assess the baseline clinical characteristics, coronary angiographic features, and adverse cardiovascular events during hospitalization and at 1 year of follow-up in obese patients compared with overweight and normal/underweight patients. Methods A prospective, multicenter study of consecutive patients undergoing percutaneous coronary intervention was performed. Results Of 2425 enrolled patients, 699 (28.8%) were obese, 1178 (48.6%) were overweight, and 548 (22.6%) were normal/underweight. Obese patients were more likely to be female and to have a higher prevalence of diabetes, hypertension, hypercholesterolemia, or previous percutaneous coronary intervention. Acute coronary syndrome was the indication for percutaneous coronary intervention in 77.0% of obese, 76.4% of overweight, and 77.4% of normal/underweight patients. No significant differences in the prevalence of multi-vessel coronary artery disease or multi-vessel percutaneous coronary intervention were found among the three groups. Additionally, no significant differences were found in stent thrombosis, readmission bleeding rates, or cardiac mortality among the three groups during hospitalization, at 1 month, and at 1 year. Conclusion The major adverse cardiovascular event rate was the same among the three groups throughout the study period. Accordingly, body mass index is considered a weak risk factor for cardiovascular comorbidities in Arab Jordanian patients.

    Purpose: The osteoid osteoma (OO) is a benign bone tumor characterized by causing severe and constant pain at night, and for that reason it requires a surgical excision. Although for years the treatment of choice has been surgery, the development of CT-guided percutaneous procedures, such as percutaneous resection with trephine (PR), and more recently the radiofrequency ablation (RF), it is possible to remove the core of the lesion and therefore relieve the symptoms in a considerably less invasive way. Material and methods: Between January 1990 and February 2004, 65 lesions in 60 patients with a presumptive diagnosis of osteoid osteoma were treated. 49 PRs and 16 RFs were performed. Of the 49 PRs, 5 required curettage and one required an ethanol injection. The procedures were guided by CT imaging under general or spinal anesthesia with 24 hr hospitalization. Tumor samples were taken for anatomical pathology analysis (AP). The absence of symptoms and late complications was verified 30 days after the procedure. Results: All lesions were accessed successfully. In 5 of them it was necessary to broaden the resection due to a possible insufficient margin. In 38 of the 65 lesions (58,5%) AP confirmed the OO diagnosis; in 6/65 (9.2%) of them AP found other specific lesions, such as enostoma (n=2), bone cyst (n=1), inclusion cyst (n=1), chondroma (n=1), and chronic osteitis (n=1), and in the rest of the cases the findings were unspecified. All patients (60/60) showed no pain within 24-48 hours of the procedure, and 5/60 (8,3%) received further treatment due to recurring symptoms. Conclusion: The percutaneous procedure has shown to be an effective technique for the treatment of OO. Compared to surgical excision, the percutaneous technique is less invasive, it requires less anesthesia and hospitalization time, and it allows an earlier return to active life. The PR is less expensive than the RF, but it requires a wider bone incision. However, both techniques are equally

    Objective: To determine the outcomes of primary percutaneous coronary intervention for ST elevation myocardial infarction complicated by cardiogenic shock. Methods: The retrospective study was conducted at the Tabba Heart Institute, a private-sector facility in Karachi. It reviewed the medical records of 56 consecutive patients between January 2009 and June 2011 with acute ST elevation myocardial infarction complicated by cardiogenic shock and subjected to primary percutaneous coronary intervention. The primary end point was in-hospital mortality and its predictors. SPSS 14 was used for statistical analysis. Results: The mean age of the study patients was 63+-11.7 years; 38 (68%) were male; 32 (57%) were hypertensive; and 39 (69%) were diabetic. Most infarcts were anterior in location (n=36; 64%). Besides, 33 (59%) required ventilatory support. Intra-aortic balloon pump was placed in 30 (54%), and 33 (59%) patients had multivessel coronary artery disease. In-hospital mortality occurred in 26 (46%). Multivariate logistic regression analysis showed that age >60 years (p= 0.05), diabetes (p <0.01) and left ventricular ejection fraction <40% (p= 0.01) were independent predictors of in-hospital mortality. Conclusions: Results emphasise the need of aggressive management of patients with cardiogenic shock utilising primary percutaneous coronary intervention as a reperfusion strategy to improve clinical outcomes.

    Minimally invasive techniques aimed at minimizing surgery-associated risk and morbidity of spinal surgery have increased in popularity in recent years. Their potential advantages include reduced length of hospital stay, blood loss, and requirement for post-operative analgesia and earlier return to work. One such minimally invasive technique is the use of percutaneous pedicle screw fixation, which is paramount for promoting rigid and stable constructs and fusion in the context of trauma, tumors, deformity and degenerative disease. Percutaneous pedicle screw insertion can be an intimidating prospect for surgeons who have only been trained in open techniques. One of the ongoing challenges of this percutaneous system is to provide the surgeon with adequate access to the pedicle entry anatomy and adequate tactile or visual feedback concerning the position and anatomy of the rod and set-screw construct. This review article discusses the history and evolution of percutaneous pedicle screw retractor technologies and outlines the advances over the last decade in the rapidly expanding field of minimal access surgery for posterior pedicle screw based spinal stabilization. As indications for percutaneous pedicle screw techniques expand, the nuances of the minimally invasive surgery techniques and associated technologies will also multiply. It is important that experienced surgeons have access to tools that can improve access with a greater degree of ease, simplicity and safety. We here discuss the technical challenges of percutaneous pedicle screw retractor technologies and a variety of systems with a focus on the pros and cons of various retractor systems. © 2016 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

    Full Text Available OBJECTIVE: This study evaluated the manner in which coronary dominance affects in-hospital outcomes of acute coronary syndrome (ACS patients undergoing percutaneous coronary intervention (PCI. BACKGROUND: Previous studies have shown that left dominant coronary anatomies are associated with worse prognoses in patients with coronary artery disease. METHODS: Data were analyzed from 4873 ACS patients undergoing PCI between September 2008 and April 2013 at 14 hospitals participating in the Japanese Cardiovascular Database Registry. The patients were grouped based on diagnostic coronary angiograms performed prior to PCI; those with right- or co-dominant anatomy (RD group and those with left-dominant anatomy (LD group. RESULTS: The average patient age was 67.6±11.8 years and both patient groups had similar ages, coronary risk factors, comorbidities, and prior histories. The numbers of patients presenting with symptoms of heart failure, cardiogenic shock, or cardiopulmonary arrest were significantly higher in the LD group than in the RD group (heart failure: 650 RD patients [14.7%] vs. 87 LD patients [18.8%], P = 0.025; cardiogenic shock: 322 RD patients [7.3%] vs. 48 LD patients [10.3%], P = 0.021; and cardiopulmonary arrest: 197 RD patients [4.5%] vs. 36 LD patients [7.8%], P = 0.003. In-hospital mortality was significantly higher among LD patients than among RD patients (182 RD patients [4.1%] vs. 36 LD patients [7.8%], P = 0.001. Multivariate logistic regression analysis revealed that LD anatomy was an independent predictor for in-hospital mortality (odds ratio, 1.75; 95% confidence interval, 1.06-2.89; P = 0.030. CONCLUSION: Among ACS patients who underwent PCI, LD patients had significantly worse in-hospital outcomes compared with RD patients, and LD anatomy was an independent predictor of in-hospital mortality.

    Full Text Available CONTEXT: Healthcare-associated infection represents the most frequent adverse event during care delivery. Medical advances like percutaneous endoscopic gastrostomy have brought improvement on quality of life to patients but an increased risk of healthcare-associated infection. Predictive risk factors for peristomal wound infection are largely unknown but evidence suggests that antibiotic prophylaxis and preventive strategies related to infection control may reduce infection rates. OBJECTIVES: The primary aim was to evaluate the global prevalence rate of peristomal infection. Secondary objectives were to characterise the positive culture results, to evaluate the prophylactic antibiotic protocol and to identify potential risk factors for peristomal infection. METHODS: Retrospective study of 297 patients with percutaneous endoscopic gastrostomy performed at a general hospital between January 2004 and September 2010. Patients received prophylactic cefazolin before the endoscopic gastrostomy procedure. Medical records were reviewed for demographic data, underling disease conditions to percutaneous endoscopic gastrostomy and patient potential intrinsic risk factors. Statistical analysis was made with the statistical program SPSS 17.0. RESULTS: A total of 297 percutaneous endoscopic gastrostomy tubes were inserted. Wound infection occurred in 36 patients (12.1%. Staphylococcus aureus methicillin resistant was the most frequently isolated microorganism (33.3% followed by Pseudomonas aeruginosa (30.6%. The incidence rate had been rising each year and differ from 4.65% in 2004/2007 to 17.9% in 2008/2010. This finding was consistent with the increasing of prevalence global infection rates of the hospital. Most of the infections (55.6% were detected in the first 10 days post procedure. There was no significant difference in age, body mass index values, mean survival time and duration of percutaneous endoscopic gastrostomy feeding between patients with and

    Percutaneous occlusion of the internal spermatic vein is a new, safe, and effective alternative therapy to surgical ligation in the treatment of spermatic varicocele. Embolization with stainless steel coils was done on 10 patients with symptomatic spermatic varicocele immediately after diagnostic venography. The results of these procedures were assessed by clinical improvement of symptoms and objective diminution of the dilated pampiniform plexus demonstrable using scrotal ultrasonography. In one patient with single coil occlusion had a recurrence, and the other 9 patients showed both clinical and ultrasonographic improvements of the varicocele. Percutaneous embolization with steel coils appeared to be effective without major complications and the savings of hospitalization and general anesthesia are important additional merits of this method being performed in the radiologic department on an outpatient basis.

    Contrast-induced nephropathy (CIN) is a significant cause of morbidity and mortality and effective strategies for its prevention are greatly needed. The purpose of this retrospective, single-center study was to investigate whether nitrate use during percutaneous coronary artery intervention reduces the incidence of CIN. Chart review of all individuals who underwent percutaneous coronary intervention (PCI) from April 2010 to March 2011 was done. Included in the study were patients who were admitted to the hospital after percutaneous coronary artery intervention and had baseline and follow-up creatinine measured. Patients with end-stage renal disease requiring dialysis and those patients with insufficient information to calculate Mehran score were excluded. There were 199 patients who met the eligibility criteria for inclusion in this study. In the identified population, postprocedure renal function was compared between 112 patients who received nitrates prior to coronary intervention and 87 who did not. Baseline characteristics were similar between the 2 groups. Contrast-induced nephropathy was defined as either a 25% or a 0.5 mg/dL, or greater, increase in serum creatinine during the first 48 to 72 hours after contrast exposure. Overall, 43 (21.6%) patients developed CIN post-PCI. Of the patients who received nitrates, 15.2% developed renal impairment when compared to 29.9% in those who did not (odds ratio [OR] = 0.42, 95% confidence interval [CI] 0.21-0.84, P = .014). Multivariate logistic regression analysis demonstrated that nitrate use was independently correlated with a reduction in the development of contrast nephropathy (OR = 0.334, 95% CI 0.157-0.709, P = .004). Additionally, of the various methods of nitrate administration, intravenous infusion was shown to be the most efficacious route in preventing renal impairment (OR = 0.42, 95% CI 0.20-0.90, P = .03). In conclusion, the use of nitrates prior to PCI, particularly intravenous nitroglycerin infusion, may

Percutaneous ASD closure has established procedural safety through operator experience and improved device structure and deliverability. There have also been advances in diagnostic capabilities. Devices have evolved from large bulky meshes to repositionable, minimal residual mesh content that easily endothelializes and conforms well to surrounding structures. Biodegradable technology has been introduced and will be closely watched as a future option. The evolution of ASD closure device usage in the last four decades incorporates development that minimizes a wide range of serious side effects that have been reported over the years. Complications reported in the literature include thrombus formation, air embolization, device embolization, erosions, residual shunts, and nickel hypersensitivity. Modern devices have intermediate to long term data with outcomes that have been favorable. Devices are available in multiple sizes with improved delivery mechanisms to recapture, reposition, and safely close simple and complex ASDs amenable to percutaneous closure. In this review, commonly used devices and deployment procedures are discussed together with a look at devices that show promise for the future.

    Full Text Available Background: Exposure to blood-borne pathogens from needle-stick and sharp injuries continues to pose a significant risk to health care workers. These events are of concern because of the risk to transmit blood-borne diseases such as hepatitis B virus, hepatitis C virus, and the human immunodeficiency virus. Objective: To benchmark different risk factors associated with needle-stick incidents among health care workers in the Ministry of Health hospitals in the Kingdom of Saudi Arabia compared to the US hospitals participating in Exposure Prevention Information Network (EPINet ™. Methods: Prospective surveillance of needle-stick and sharp incidents carried out during the year 2012 using EPINet™ ver 1.5 that provides uniform needle stick and sharp injury report form. Results: The annual percutaneous incidents (PIs rate per 100 occupied beds was 3.2 at the studied MOH hospitals. Nurses were the most affected job category by PIs (59.4%. Most PIs happened in patients' wards in the Ministry of Health hospitals (34.6%. Disposable syringes were the most common cause of PIs (47.20%. Most PIs occurred during use of the syringes (36.4%. Conclusion: Among health care workers, nurses and physicians appear especially at risk of exposure to PIs. Important risk factors of injuries include working in patient room, using disposable syringes, devices without safety features. Preventive strategies such as continuous training of health care workers with special emphasis on nurses and physicians, encouragement of reporting of such incidents, observation of sharp handling, their use and implementation of safety devices are warranted.

    Tracheostomy is considered the airway management of choice for patients who need prolonged mechanical ventilation support. Percutaneous Dilatational Tracheotomy (PDT) is a technique that can be performed easily and rapidly at bedside and is particularly useful in the intensive care setting. The Griggs percutaneous tracheotomy is unique in its utilization of a guide wire dilator forceps. We aimed to describe the early perioperative and late postoperative complications of PDT using the Griggs technique in patients in the intensive care unit (ICU). This cross-sectional study was conducted on all patients who underwent tracheostomy in the ICU of the Imam Reza Hospital of Kermanshah, Iran, from June 2011 to June 2015. PDT was performed in 184 patients with the Griggs technique. Demographic variables, as well as perioperative and late postoperative complications were recorded. The mean age of patients was 57.3 ± 15.37 years. The most common primary causes of tracheostomy were hypoxic brain damage disorders (43.2%) and pneumonia (14.8%). Perioperative and early complications occurred in 16.7 % of procedures, of which 9.3% were bleedings (minor, significant and major). Furthermore, the incidence of late complications was 8.6%, including: stomal infection, difficult replace tracheostomy tube, tracheoesophageal fistula, tracheal stenosis, and tracheomalacia. PDT via Griggs technique is a safe, quick, and effective method. The low incidence of complications indicates that bedside percutaneous tracheostomy can be performed safely as a routine procedure for daily care implemented in the ICU.

    To investigate the value of percutaneous balloon dilation and percutaneous transhepatic cholangial drainage (PTCD) catheter maintenance in the treatment of benign biliary strictures. The clinical data of 21 patients with benign biliary strictures at Peking Union Medical College Hospital from June 2005 to June 2011 were retrospectively studied, in which 12 patients in severe stricture (stenosis > 70%) were treated with percutaneous balloon dilation and PTCD catheter placed across the stricture, while another 9 patients in median stricture (stenosis stenosis was seen in 2 patients. A severe complication with biliary artery branch rupture and massive hemobilia was seen in 1 patient during balloon dilation. Of the 9 patients only treated with 1 - 12 months (median: 6 months) of PTCD catheter placement, 7 patients had the catheter successfully removed. In the follow-up of 5 - 18 months (median: 8 months), patency of bile duct was preserved in 5 of 7 patients, and recurrent stenosis was seen in 2 patients. No severe complication occurred. When endoscopy therapy is failed or the patient can't undergo endoscopy therapy, the percutaneous balloon dilation and PTCD catheter maintenance method is an effective alternative therapeutic approach in the treatment of benign biliary strictures. The moderate benign biliary stricture may be effectively treated only by the PTCD catheter maintenance method.

    Full Text Available The article describes the clinical case in a patient with bilateral nephrolithiasis, chronic kidney disease of the 4th stage, after which bleeding from the left kidney developed after simultaneous bilateral percutaneous nephrolithotomy (PNL, leading to severe hemic hypoxia. Conservative therapy, blood transfusion did not lead to a persistent effect, the bleeding continued to recur. Given the presence of chronic renal failure (CRF from the embolization of the branches of the renal artery, it was decided to abstain, given the extremely high risk of aggravation of nephropathy after the administration of the contrast drug. Left-sided nephrectomy would inevitably lead to the development of terminal chronic renal failure. Patients performed an electrocoagulation of the fistula wall with a Karl Storz 26C resectoscope in 60W mode. The bleeding was completely stopped. The patient is discharged from the hospital in a satisfactory condition. At the time of discharge in the conduct of replacement renal therapy did not need. When analyzing publications in The Cochrane Library, PubMed, Medline and Web of Science, we did not find a description of such a method of hemostasis.

    Nutritional support by gastrostomy feeding is an important treatment adjunct when major swallowing difficulty or debilitating diseases is present. This technique for percutaneous placement of a gastric feeding tube now provides many patients with a simple, safe, and well-tolerated alternative to surgical feeding gastrostomy. We experienced 27 cases of percutaneous gastrostomy from January 1989 to February 1991 at Kyungpook National University Hospital. The underlying diseases of the patients were esophageal cancer (11), pyriform sinus cancer (4), laryngeal cancer (3), tongue cancer (2), lye stricture (1), lung cancer (1), chordoma (1), lethal midline granuloma (1), malignant lymphoma (1), maxillary cancer (1), and tonsil cancer (1). Selding method was used in all cases. In five patients it was difficult to insert the nasogastric tube for air insufflation, and one patient had subtotal gastrectomy with gastrojejunostomy, but gastrostomy was performed in all cases. The general condition improved in all patients. We experienced one case of mild peritonitis, but no other significant complications were observed. Gastrostomy tubes were patient in all patients during their survival period, except two patients who experienced obstruction 2 and 6 months after the procedure. Percutaneous gastrostomy can be used safely and effectively in such patients who have pharyngoesophageal or CNS lesions precluding oral intake

    The aim of this study is to evaluate the short and long-term results of percutaneous tracheostomy in patients with documented cervical spine fracture. Between June 2000 and September 2005, 38 consecutive percutaneous tracheostomy procedures were performed on multi-trauma patients with cervical spine fracture. Modified Griggs technique was employed at the bedside in the general intensive care department. Staff thoracic surgeons and anesthesiologists performed all procedures. Demographics, anatomical conditions, presence of co-morbidities and complication rates were recorded. The average operative time was 10 min (6-15). Two patients had minor complications. One patients had minor bleeding (50 cc) and one had mild cellulitis. Nine patients had severe paraparesis or paraplegia prior to the PCT procedure and 29 were without neurological damage. There was no PCT related neurological deterioration. Twenty-eight patients were discharged from the hospital, 21 were decannulated. The average follow-up period was 18 months (1-48). There was no delayed, procedure related, complication. These results demonstrate that percutaneous tracheostomy is feasible and safe in patients with cervical spine fracture with minimal short and long-term morbidity. We believe that percutaneous tracheostomy is the procedure of choice for patients with cervical spine fracture who need prolonged ventilatory support.

    Purpose: This study was designed to evaluate retrospectively the safety and efficacy of the percutaneous management of duodenal stump leakage with a Foley catheter after subtotal gastrectomy. Methods: Ten consecutive patients (M:F = 9:1, median age: 64 years) were included in this retrospective study. The duodenal stump leakages were diagnosed in all the patients within a median of 10 days (range, 6–20). At first, the patients underwent percutaneous drainage on the day of or the day after confirmation of the presence of duodenal stump leakage, and then the Foley catheters were replaced at a median of 9 days (range, 6–38) after the percutaneous drainage. Results: Foley catheters were placed successfully in the duodenal lumen of all the patients under a fluoroscopic guide. No complication was observed during and after the procedures in all the patients. All of the patients started a regular diet 1 day after the Foley catheter placement. The patients were discharged at a median of 7 days (range, 5–14) after the Foley catheter placement. The catheters were removed in an outpatient clinic 10–58 days (median, 28) after the Foley catheter placement. Conclusions: Fluoroscopy-guided percutaneous Foley catheter placement may be a safe and effective treatment option for postoperative duodenal stump leakage and may allow for shorter hospital stays, earlier oral intake, and more effective control of leakage sites

    Percutaneous ureteral stent insertion is a treatment of permanent or temporary urinary diversion to maintain continuity and function of the obstructed and injured ureter. We performed 31 cases of percutaneous double pig tall ureteral stent insertion in 21 patients, included 13 patients with malignant ureteral obstruction and eight patients with injured ureter as well as benign inflammatory stricture. Satisfactory resulted was obtained in all patients but one, who need percutaneous nephrostomy on week later for urinary diversion. No significant complication was encountered. The authors concluded that percutaneous ureteral stent insertion, an interventional procedure alternative to urologic retrograde method, is an effective method for urinary diversion.

    In the ATLANTIC (Administration of Ticagrelor in the catheterization laboratory or in the Ambulance for New ST elevation myocardial Infarction to open the Coronary artery) trial the early use of aspirin, anticoagulation, and ticagrelor coupled with very short medical contact-to-balloon times represent good indicators of optimal treatment of ST-elevation myocardial infarction and an ideal setting to explore which factors may influence coronary reperfusion beyond a well-established pre-hospital system. This study sought to evaluate predictors of complete ST-segment resolution after percutaneous coronary intervention in ST-elevation myocardial infarction patients enrolled in the ATLANTIC trial. ST-segment analysis was performed on electrocardiograms recorded at the time of inclusion (pre-hospital electrocardiogram), and one hour after percutaneous coronary intervention (post-percutaneous coronary intervention electrocardiogram) by an independent core laboratory. Complete ST-segment resolution was defined as ≥70% ST-segment resolution. Complete ST-segment resolution occurred post-percutaneous coronary intervention in 54.9% ( n=800/1456) of patients and predicted lower 30-day composite major adverse cardiovascular and cerebrovascular events (odds ratio 0.35, 95% confidence interval 0.19-0.65; pST-segment resolution were the time from symptoms to pre-hospital electrocardiogram (odds ratio 0.91, 95% confidence interval 0.85-0.98; pST-segment resolution (odds ratio 1.22, 95% confidence interval 0.99-1.51; p=0.06). This study confirmed that post-percutaneous coronary intervention complete ST-segment resolution is a valid surrogate marker for cardiovascular clinical outcomes. In the current era of ST-elevation myocardial infarction reperfusion, patients' delay and diabetes mellitus are independent predictors of poor reperfusion and need specific attention in the future.

We aimed to compare the surgical outcomes of PCNLs performed using our modified supine position with those performed in the standard prone position. Materials and Methods: A prospective group of 236 renal units (224 patients undergoing PCNL were included in this 2 site study: 160 were performed in the modified supine position were compared with 76 undergoing PCNL in the prone position. The outcomes of radiation dose, radiation time, stone free rate, body mass index (BMI, stone size, operative time, length of stay (LOS, in hospital and complications were compared. Chi-square and t-tests were used. Results: There were no significant differences in mean radiation time, radiation dose or stone size between the modified supine and prone groups. The supine group had a higher mean BMI (31 kg/m2 vs. 28 kg/m2 , p=0.03, shorter mean surgical time (93 minutes vs. 123 minutes, p<0.001, shorter mean LOS (2 days vs. 3 days, p=0.005 and higher stone free rate (70% vs. 50%, p=0.005. There were no differences in septic or bleeding complications but the prone group had a higher rate of overall complications. Conclusions: Modified supine PCNL has significantly lower operative time, shorter LOS and higher stone-free rate compared with prone in our series, while remaining a safe procedure.

    In this paper, the authors report 20 cases of percutaneous extraction of osteoid osteoma under CT guidance. Typical pain and findings of plain radiography, bone scintigraphy, and CT were suggestive of the lesion. They were located on the lower limb (n = 16), acetabulum (n = 3), and vertebra (n = 1). Percutaneous extraction is performed under general anesthesia in the CT room. The authors describe the procedure of nidus extraction. CT allowed total removal of the nidus. There are no residual paid 1-3 days after the procedure. findings of clinical and plain radiographic follow-up are satisfactory (3-18 months). Histologic confirmation was obtained in all cases. This new technique of osteoid osteoma extraction under CT guidance allows precise removal of the nidus with pathologic verification. The duration of hospitalization and the therapeutic cost are widely reduced

    The study was aimed to the evaluation of the effectiveness and results of ultrasound guided percutaneous nephrolithotripsy (PNL) for the treatment of patients with large stones in renal pelvis. The results of PNL in 138 patients who underwent surgery for kidney stones from 2011 to 2013 were analyzed. Seventy patients (Group 1) underwent surgery with combined ultrasound and radiological guidance, and 68 patients (Group 2)--only with ultrasound guidance. The study included patients with large renal pelvic stones larger than 2.2 cm, requiring the formation of a single laparoscopic approach. Using the comparative analysis, the timing of surgery, the number of intra- and postoperative complications, blood loss and length of stay were evaluated. Percutaneous access was successfully performed in all patients. Postoperative complications (exacerbation of chronic pyelonephritis, gross hematuria) were observed in 14.3% of patients in Group 1 and in 14.7% of patients in Group 2. Bleeding requiring blood transfusion, and injuries of adjacent organs were not registered. Efficacy of PNL in the Group 1 was 95.7%; 3 (4.3%) patients required additional interventions. In Group 2, the effectiveness of PNL was 94.1%, 4 (5.9%) patients additionally underwent extracorporeal lithotripsy. There were no significant differences in the effectiveness of PNL, the volume of blood loss and duration of hospitalization. Ultrasound guided PNL can be performed in large pelvic stones and sufficient expansion of renal cavities, thus reducing radiation exposure of patients and medical staff.

    Percutaneous intervention procedures in obstructive uropathy include percutaneous nephrostomy tube placements, nephroureteral stents, percutaneous nephrostomy combined with ureteral embolization, percutaneous management of stone disease, suprapubic tube placements into the bladder, and perinephric/retroperitoneal urinomas/abscesses drainages. Percutaneous nephrostomy is performed to relieve urinary obstruction or divert the urinary stream away from the ureter or bladder. Patients are given preprocedure antibiotics. Percutaneous nephrostomies can be emergent cases because of risk of pyuria and sepsis from a stagnant urine collection. The procedure is performed using both ultrasound and fluoroscopy (or fluoroscopy alone using anatomic landmarks, or an internal radiopaque calculus, or delayed phase excretion of the contrast into the renal collecting system) under local anesthesia or conscious sedation. Ureteral stents are placed to bypass an obstructing stone or to stent across of an area of stricture or ureteral laceration. Stents may be placed by the urologist via a transurethral approach or by the interventional radiologist via a percutaneous approach. The decision as to method of stent placement is based upon the location and accessibility of the ureteral pathology. Ureteral embolization is performed in patients with unresectable tumors of the pelvis with long-standing nephrostomy tubes and distal urine leaks refractory to other treatments. Coils, gelfoam and liquid embolic materials can be used. Ureteral embolization for ureteral fistulas and incontinence is technically successful in 100% of the patients. Complications include bleeding, infection, ureteral or renal injury, and deployment (or movement) of the coils within the renal pelvis. Percutaneous management of stone disease, including renal, ureteral, and bladder stones requires close cooperation between the urologist and interventional radiologist, because of availability of sonographic lithotripsy

    The patent ductus arteriosus (PDA) represents one of the most prevalent diseases in hospitals which treat congenital heart diseases (CHD). Currently, in groups of more than 1 year of age percutaneous closure it is the standard therapy. The aim of this paper is to determine the frequency, characteristics and treatment of PCA in congenital heart disease service at the a Cardiology Hospital in Mexico. In clinical CHD our hospital, a descriptive study of 2010-2015 of patients who were treated with percutaneous closure PCA and surgery was performed. They were divided into the following ages: infant, preschool, children, adolescents and adults. The absolute frequencies were recorded. 187 patients of preschool and school which accounted for 60% of the total sample were obtained. Percutaneous closure catheterization was performed in 90%; 2% of complications were recorded. In this clinic, the PCA is treated mostly by interventional catheterization in most stages of the human being with minimal complications.

    This review aims to assess the effectiveness of percutaneous vertebroplasty as a treatment for the severe refractory pain associated with vertebral fracture, in a group of patients with fractures secondary to either osteoporotic or neoplastic disease. A retrospective review of 20 patients treated with percutaneous vertebroplasty in Cork University Hospital up until March 2007 was carried out and a questionnaire was prepared and distributed. Prior to vertebroplasty, patients had been symptomatic with severe pain for a mean of 20.9 weeks. Of those thirteen whom replied to a postal questionnaire, 12 (92.3%) reported pain relief and this improvement occurred within 7 days in 9 (81.8%). This was associated with decreased analgesic requirements, as determined on chart review. Prior to the procedure only 5 (38.4%) were independently mobile and this figure rose to 10 (76.9%) afterwards, occurring within one week in the majority. Subjective outcomes were better in the group of patients with neoplasm-induced fractures.

    The aim of this study was to perform a budget impact analysis on the adoption of percutaneous occlusion of ostium secundum atrial septal defects in the Brazilian Unified National Health System. Costs were collected using micro-costing technique from medical records for each treatment technique (conventional surgery versus percutaneous septal occluder) at a public federal hospital specialized in high-complexity cardiology. The analysis showed that expenditures associated with percutaneous occlusion were lower than with conventional surgery, and sensitivity analysis confirmed the cost reduction in several scenarios, showing a significant budget impact with a 30% adoption rate for the percutaneous occluder (savings of approximately 1.5 million dollars per year). The study indicates that the adoption of the percutaneous septal occluder would mean cost savings of approximately 3.5 million dollars for the Brazilian public health system.

    Recurrent diverticulitis has been reported in up to 30% to 40% of patients who recover from an episode of colonic diverticular abscess, so elective interval resection is traditionally recommended. The aim of this study was to review the outcomes of patients who underwent percutaneous drainage of colonic diverticular abscess without subsequent operative intervention. This was an observational study. This investigation was conducted at a tertiary care academic medical center and a single-hospital health system. Patients treated for symptomatic colonic diverticular abscess from 2002 through 2007 were included. The primary outcomes measured were complications, recurrence, and colectomy-free survival. Two hundred eighteen patients underwent percutaneous drainage of colonic diverticular abscesses. Thirty-two patients (15%) did not undergo subsequent colonic resection. Abscess location was pelvic (n = 9) and paracolic (n = 23), the mean abscess size was 4.2 cm, and the median duration of percutaneous drainage was 20 days. The comorbidities of this group of patients included severe cardiac disease (n = 16), immunodeficiency (n = 7), and severe pulmonary disease (n = 6). Freedom from recurrence at 7.4 years was 0.58 (95% CI 0.42-0.73). All recurrences were managed nonoperatively. Recurrence was significantly associated with an abscess size larger than 5 cm. Colectomy-free survival at 7.4 years was 0.17 (95% CI 0.13-0.21). This study was limited by its retrospective, nonexperimental design and short follow-up. In selected patients, observation after percutaneous drainage of colonic diverticular abscess appears to be a safe and low-risk management option.

    Full Text Available Aim: Today, PNL has become primary treatment alternative in multiple or large kidney stones where ESWL treatment has failed. In our study, we have analyzed the facts that affect hemorrhage in PNL surgeries. Material and Method: Between March 2008 and December 2009, 204 patient%u2019s histories who had undergone percutaneous nephrolithotomy surgery in Izmir Bozyaka Training & Research Hospital, Urology Department were analyzed retrospectively. The patients were assembled under four groups according to the effect of some factors related to stone (size and localization, operation (number and localization of the entrances and the effects of PNL hemorrhage between these groups was investigated. Results: Of the 204 patients undergoing percutaneous nephrolithotomy, 76 were female, 128 were male, with an average age of 46.9±14.2 (18-80. The preoperation and postoperation Hb differences of the 176 patients whose stone load was less than 1000 mm2 and 28 patients whose stone load was over 1000 m2 were compared, yielding no statistically significant difference (p=0.942. Also no statistically significant difference was observed with regard to stone type, number of entries and percutaneous entry location. Discussion: In our study, it has been observed the size and localization of the stone is not an independent factor that affects the hemorrage itself. And also it has been observed that number and localization of entrances are not an independent factor that affecting haemorrhage.

    Full Text Available Introduction: Percutaneous nephrolithotomy (PCNL has witnessed rapid advancements, the latest being ultra-mini-percutaneous nephrolithotomy (UMP, which makes the use of 11-13F sheaths as compared to 24-30F sizes used in conventional PCNL. This miniaturization aims to reduce morbidity and improve patient outcomes. We evaluated the safety and efficacy of UMP and report our ourtcomes. Patients and Methods: A total of 120 patients underwent UMP from July 2012 to March 2014. These patients had a single unilateral renal stone measuring between 8 and 20 mm. All patients underwent UMP using a 3F nephroscope, 7.5F inner sheath, and 11F or 13F outer metallic cannula, which served as the Amplatz sheath. Stone fragmentation and clearance were achieved with holmium laser. No nephrostomy or stent was used routinely. Results: Complete stone fragmentation was achieved in 114 out of 120 patients (95% using UMP; whereas the remaining 6 were converted into mini-PCNL using a 12.5F nephroscope and 15F Amplatz sheath. The mean operative time was 39.7 ± 15.4 min, and the mean postoperative hospital stay was 22.3 ± 2.2 h. Postoperatively, 6 (5% patients had residual fragments measuring ≤4 mm. At the 2 weeks follow-up, the stone-free status was >99% (119/120. There were no significant postoperative complications. Conclusion: This study shows UMP to be an effective and safe procedure for managing stones up to 20 mm. This procedure offers an attractive alternative to shock wave lithotripsy and retrograde intrarenal surgery for managing small stones.

    To evaluate the technical feasibility and clinical efficacy of percutaneous transhepatic cholecystolithotomy under fluoroscopic guidance in high-risk surgical patients with acute cholecystitis. Sixty-three consecutive patients of high surgical risk with acute calculous cholecystitis underwent percutaneous transhepatic gallstone removal under conscious sedation. The stones were extracted through the 12-Fr sheath using a Wittich nitinol stone basket under fluoroscopic guidance on three days after performing a percutaneous cholecystostomy. Large or hard stones were fragmented using either the snare guide wire technique or the metallic cannula technique. Gallstones were successfully removed from 59 of the 63 patients (94%). Reasons for stone removal failure included the inability to grasp a large stone in two patients, and the loss of tract during the procedure in two patients with a contracted gallbladder. The mean hospitalization duration was 7.3 days for acute cholecystitis patients and 9.4 days for gallbladder empyema patients. Bile peritonitis requiring percutaneous drainage developed in two patients. No symptomatic recurrence occurred during follow-up (mean, 608.3 days). Fluoroscopy-guided percutaneous gallstone removal using a 12-Fr sheath is technically feasible and clinically effective in high-risk surgical patients with acute cholecystitis

    To assess the effect of percutaneous endoscopic gastrostomy on short- and long-term survival of patients in a persistent vegetative state after stroke and determine the relevant prognostic factors. Stroke may lead to a persistent vegetative state, and the effect of percutaneous endoscopic gastrostomy on survival of stroke patients in a persistent vegetative state remains unclear. Prospective study. A total of 97 stroke patients in a persistent vegetative state hospitalised from January 2009 to December 2011 at the Second Hospital, University of South China, were assessed in this study. Percutaneous endoscopic gastrostomy was performed in 55 patients, and mean follow-up time was 18 months. Survival rate and risk factors were analysed. Median survival in the 55 percutaneous endoscopic gastrostomy-treated patients was 17·6 months, higher compared with 8·2 months obtained for the remaining 42 patients without percutaneous endoscopic gastrostomy treatment. Univariate analyses revealed that age, hospitalisation time, percutaneous endoscopic gastrostomy treatment status, family financial situation, family care, pulmonary infection and nutrition were significantly associated with survival. Multivariate analysis indicated that older age, no gastrostomy, poor family care, pulmonary infection and poor nutritional status were independent risk factors affecting survival. Indeed, percutaneous endoscopic gastrostomy significantly improved the nutritional status and decreased pulmonary infection rate in patients with persistent vegetative state after stroke. Interestingly, median survival time was 20·3 months in patients with no or one independent risk factors of poor prognosis (n = 38), longer compared with 8·7 months found for patients with two or more independent risk factors (n = 59). Percutaneous endoscopic gastrostomy significantly improves long-term survival of stroke patients in a persistent vegetative state and is associated with improved nutritional status

    To evaluate the effectiveness of percutaneous biliary stone removal as a primary treatment in cases with difficulties to use an endoscopy. From March 2004 to May 2011, 17 patients who underwent primary percutaneous biliary stone removal (Group 1) and 34 case-matched patients who underwent primary endoscopic biliary stone removal were selected (Group 2). The inclusion criteria were as follows: patients who had 1) ≥ 15 mm bile duct stones, 2) intrahepatic bile duct stones, 3) bile duct stones with a history of previous gastrointestinal bypass surgery. In the present study were analyzed the success rates, the length of postprocedural hospital stay, the change of Amylase/Lipase values and complications post procedure. Statistical analysis was performed using paired t-test and unpaired t-test. The success rate was higher in Group 1 (94.1%) than in Group 2 (85.3%). Length of post procedural hospital stay and the post procedural amylase level were significantly increased in Group 2 (p = 0.036 and p = 0.017, respectively). In cases of bile duct stones with difficulties in the use of an endoscopy a percutaneous biliary stone removal can be efficient as a primary treatment.

    A prospective randomized study was executed to compare the surgical parameters and stone clearance in patients who underwent percutaneous nephrolithotomy (PNL) under combined spinal-epidural anesthesia (CSEA) versus those who underwent PNL under general anesthesia (GA). Between January 2008 to December 2009, 64 patients with renal calculi were randomized into 2 groups and evaluated for the purpose of this study. Group 1 consisted of patients who underwent PNL under CSEA and Group 2 consisted of patients who underwent PNL under GA. The operative time, stone clearance rate, visual pain analog score, mean analgesic dose and mean hospital stay were compared amongst other parameters. The difference between visual pain analog score after the operation and the dose of analgesic requirement was significant on statistical analysis between both groups. PNL under CSEA is as effective and safe as PNL under GA. Patients who undergo PNL under CESA require lesser analgesic dose and have a shorter hospital stay. Copyright © 2011 S. Karger AG, Basel.

    The authors describe the techique employed for percutaneous trans-hepatic sphincterotomy as performed on 3 patients with common bile duct (CBD) stones. In all patients, previous endoscopic attempt had failed for anatomical reasons (Billroth II gastric resection or partial gastric resection with brown anastomosis), and the ampulla could not be correctly incannulated with the sphincterotome. In all aptients endoscopy was useful to check the position of the diethermic loop inserted percutaneously. Conplete and immediate success was obtained in all 3 cases. No major complications occurred during transhepatic treatment. To date, 1 recurrence has been observed, and the patient has been retreated with bilioplasty. All patients were followed after 5-6 months with US, plain X-rays of the abdomen and blood tests (γGt, alkaline phosphatase, and bilirubinemia). The authors suggest that percutaneous transhepatic sphincterotomy be employed electively in patients with biliary tree diseases in case the endoscopic approach failes

    Objectives: To determine whether staged percutaneous coronary intervention (PCI) within the same hospitalization as primary PCI is safe. Background: In ST-segment elevation myocardial infarction (STEMI) patients with multivessel disease undergoing primary PCI, staged non-culprit vessel PCI at a separate session is recommended. Methods: We conducted a retrospective analysis of 282 consecutive STEMI patients with multivessel disease who underwent primary PCI followed by staged PCI of the non-culprit vessel. Patients were categorized into staged PCI in the same hospitalization (n = 184) and staged PCI at a separate hospitalization within 8 weeks of primary PCI (n = 98). Results: Baseline characteristics, presentation of STEMI, and procedural characteristics were similar in both groups. Contrast amount was higher in the separate hospitalization group for both index (175 vs. 153 ml, p = 0.011) and staged (144 vs. 120 ml, p = 0.004) procedures. More staged left main PCI was performed in the separate hospitalization group (3.9 vs. 0.3%, p = 0.008). Angiographic success of staged PCI was similar in both groups, with similar rates of vascular complications and major bleeding. Following staged PCI, in-hospital major adverse cardiac events (3.3 vs. 1.0%, p = 0.43) and mortality (2.7 vs. 0%, p = 0.17) were similar in both groups. Conclusions: Our study supports the safety and feasibility of staged PCI within the same hospitalization as primary PCI, achieving similar procedural success and in-hospital outcomes as staged PCI at a separate hospitalization. Higher contrast amount used during primary PCI and presence of left main lesion in non-culprit vessels may influence the decision to stage the PCI at a separate hospitalization

    There is limited experience of percutaneous biliary interventions in children although they are safe and effective procedures. To evaluate the efficacy and safety of percutaneous management of tumoral biliary obstruction in children. Percutaneous biliary interventions were performed in eight children (six boys, two girls) with a mean age of 10.5 years (range 4-17 years). The interventions included percutaneous biliary drainage (five patients), percutaneous biliary drainage and placement of a self-expanding metallic stent (two patients), and percutaneous cholecystostomy (one patient). All patients had signs of obstructive jaundice and two had cholangitis. All procedures were successful. No procedure-related mortality was observed. Bilirubin levels returned to normal in four of the eight patients. Findings of cholangitis resolved in the two affected patients after the procedure and antibiotic treatment. Two patients underwent surgery after percutaneous biliary drainage procedures. A self-expanding metallic stent was placed in two patients with malignancy and the stents remained patent until death. Percutaneous biliary interventions can be performed safely for the management of tumoral biliary obstruction in children. (orig.)

    2010-01-01

    Sigmoid volvulus is a common cause of large bowel obstruction in western countries and Africa. It accounts for 25% of the patients admitted to the hospital for large bowel obstruction. The acute management of sigmoid volvulus is sigmoidoscopic decompression. However, the recurrence rate can be as high as 60% in some series. Recurrent sigmoid volvulus in elderly patients who are not fit for definitive surgery is difficult to manage. The percutaneous endoscopic placement of two percutaneous endoscopic colostomy tube placement is a simple and relatively safe procedure. The two tubes should be left open to act as vents for the colon from over-distending. In our opinion, this aspect is key to its success as it keeps the sigmoid colon deflated until adhesions form between the colon and the abdominal wall. PMID:20339184

    Eptifibatide, a small-molecule glycoprotein IIb/IIIa inhibitor, is conventionally administered as a bolus plus infusion. A growing number of clinicians are using a strategy of catheterization laboratory-only eptifibatide (an off-label use) as procedural pharmacotherapy for patients undergoing percutaneous coronary intervention although the comparative effectiveness of this approach is unknown. We compared the in-hospital outcome of patients undergoing percutaneous coronary intervention across 47 hospitals and treated with eptifibatide bolus plus infusion with those treated with a catheterization laboratory-only regimen. We used optimal matching to link the use of catheterization laboratory-only eptifibatide with clinical outcomes, including mortality, myocardial infarction, bleeding, and need for transfusion. Of the 84 678 percutaneous coronary interventions performed during 2010 to 2011, and meeting our inclusion criteria, eptifibatide was administered to 21 296 patients. Of these, a catheterization laboratory-only regimen was used in 4511 patients, whereas 16 785 patients were treated with bolus plus infusion. In the optimally matched analysis, compared with bolus plus infusion, a catheterization laboratory-only regimen was associated with a reduction in bleeding (optimally matched adjusted odds ratio, 0.74; 95% confidence interval, 0.58-0.93; P=0.014) and need for transfusion (optimally matched adjusted odds ratio, 0.70; 95% confidence interval, 0.52-0.92; P=0.012), with no difference in mortality or myocardial infarction. A catheterization laboratory-only eptifibatide regimen is commonly used in clinical practice and is associated with a significant reduction in bleeding complications in patients undergoing contemporary percutaneous coronary intervention. © 2015 American Heart Association, Inc.

    Current guidelines recommend early invasive intervention (<24 hr) for high risk patients with non-ST-segment elevation myocardial infarction (NSTEMI). A delayed invasive strategy (24-72 hr) is considered reasonable for low risk patients. The real-world effectiveness of this strategy is unknown. The ARIC Study has conducted hospital surveillance of acute myocardial infarction (MI) since 1987. NSTEMI was classified using a validated algorithm. We limited our study to patients undergoing early (<24 hr of the event onset), or late (≥24 hr) percutaneous coronary intervention (PCI). Patients were stratified into low (TIMI score 2-4), and high risk (TIMI score 5-7, or presence of cardiogenic shock, ventricular fibrillation, or cardiac arrest). Associations between early versus late PCI and mortality were analyzed using multivariable logistic regression adjusted for demographics, hospitalization year, TIMI score, and comorbidities. From 1987 to 2012, 6,746 patients were hospitalized with NSTEMI and underwent PCI. Most were white (79%), male (68%), with mean age 61 years. The 28-day and 1-year mortality were 2% and 5%, respectively. Most revascularizations (65%) were late. After accounting for potential confounders, early PCI was associated with a 58% reduced 28-day mortality (OR = 0.42; 95% CI: 0.21-0.84) for the entire population, and 57% reduced mortality (OR = 0.43; 95% CI: 0.21-0.88) for high risk patients. By 1-year of follow up, there was no significant difference in mortality with respect to early vs. late PCI. In hospitalized NSTEMI patients with high risk of clinical events, early PCI is associated with improved 28-day survival. © 2017 Wiley Periodicals, Inc.

    ST-elevation myocardial infarction (STEMI) guidelines recommend reperfusion by primary percutaneous coronary intervention (PCI) ≤ 90 min from time of first medical contact (FMC). This strategy is challenging in rural areas lacking a nearby PCI-capable hospital. Recommended reperfusion times can be achieved for STEMI patients presenting in rural areas without a nearby PCI-capable hospital by ground transportation to a central PCI-capable hospital by use of protocol-driven emergency medical service (EMS) STEMI field triage protocol. Sixty STEMI patients directly transported by EMS from three rural counties (Nassau, Camden and Charlton Counties) within a 50-mile radius of University of Florida Health-Jacksonville (UFHJ) from 01/01/2009 to 12/31/2013 were identified from its PCI registry. The STEMI field triage protocol incorporated three elements: (1) a cooperative agreement between each of the rural emergency medical service (EMS) agency and UFHJ; (2) performance of a pre-hospital ECG to facilitate STEMI identification and laboratory activation; and (3) direct transfer by ground transportation to the UFHJ cardiac catheterization laboratory. FMC-to-device (FMC2D), door-to-device (D2D), and transit times, the day of week, time of day, and EMS shift times were recorded, and odds ratio (OR) of achieving FMC2D times was calculated. FMC2D times were shorter for in-state STEMIs (81 ± 17 vs . 87 ± 19 min), but D2D times were similar (37 ± 18 vs . 39 ± 21 min). FMC2D ≤ 90 min were achieved in 82.7% in-state STEMIs compared to 52.2% for out-of-state STEMIs (OR = 4.4, 95% CI: 1.24-15.57; P = 0.018). FMC2D times were homogenous after adjusting for weekday vs . weekend, EMS shift times. Nine patients did not meet FMC2D ≤ 90 min. Six were within 10 min of target; all patient achieved FMC2D ≤ 120 min. Guideline-compliant FMC2D ≤ 90 min is achievable for rural STEMI patients within a 50 mile radius of a PCI-capable hospital by use of protocol-driven EMS ground

    The antegrade colonic enema is accepted as effective for management of intractable constipation in children when conventional bowel management has failed. This study describes experience with a new, minimally invasive technique, the distal antegrade colonic enema, which involves percutaneous endoscopic colostomy of the left colon. Fifteen children with refractory constipation and soiling who had radiographic evidence of megarectum and/or distal colonic delay were selected for the procedure. The junction of the descending and the sigmoid colon was identified colonoscopically, and the percutaneous endoscopic colostomy tube, through which antegrade distal colonic enema are administered, was inserted. Fourteen children underwent distal percutaneous endoscopic colostomy insertion. The median time required for the procedure was 30 minutes (20-50 minutes). Excluding one child (technical difficulties with percutaneous endoscopic colostomy placement), median post-procedural hospital stay was 4 days (2-27 days). Thirteen children were no longer soiling, and improvement in quality of life was reported at 2 months' follow-up. At 6 months' follow-up, 90% of children were clean during intervals between enemas. All children evaluated at 12 months' follow-up remained clean. Median duration of follow-up was 12.5 months (2-51 months). The distal percutaneous endoscopic colostomy is a simple alternative to established methods for delivery of antegrade enemas. It is less invasive and on reversal leaves only minor scarring.

    Full Text Available Renal transplantation, performed per million population, ranges from 30 to 60 in developed countries. The transplanted kidney is generally placed in iliac fossa; therefore the treatment procedure of the pelvic trauma in these patients should be selected carefully. The gold standard technique for the treatment of displaced acetabulum fractures is open reduction and internal fixation. Our patient had received a living-related-donor renal transplant due to chronic renal failure. In the second year of transplantation, she had been injured in a motor-vehicle accident, and radiographs showed a right acetabular anterior column fracture and left pubic rami fractures. The patient was treated with percutaneous fixation techniques and at one year of postoperative period there was no evidence of degenerative signs and the clinical outcome was good. Beside having the advantage of avoiding dissection through the iliac fossa by the standard ilioinguinal approach, percutaneous techniques, with shorter surgical time, decreasing soft tissue disruption, and the potential for early discharge from hospital might be ideal for a renal transplant recipient carrying a higher risk of infection. Percutaneous fixation of selected acetabular fractures in a renal transplant recipient would presumably have the potential to decrease the morbidity associated with traditional open surgical procedures.

    Objective: To analyze the causes and clinical manifestations of hepatic arterial hemorrhage which occurred after percutaneous transhepatic biliary drainage and to summarize the practical experience in its diagnosis and treatment in order to decrease its incidence and mortality. Methods: During the period from June 2007 to June 2010, percutaneous transhepatic biliary drainage was carried out in 622 cases, of which DSA-proved postoperative hepatic arterial hemorrhage occurred in 11, including bile duct hemorrhage (n=6), abdominal cavity bleeding (n=3) and combination of bile duct and abdominal cavity (n=2). Interventional embolization of the bleeding branches of hepatic artery with Gelfoam and coils was carried out in all 11 patients. The clinical data such as clinical manifestations and therapeutic results were retrospectively analyzed. Results: After interventional embolization therapy for postoperative hepatic arterial hemorrhage the bleeding stopped in ten patients, who were discharged from hospital when the clinical conditions were alleviated. The remaining one patient died of sustained deterioration in hepatic and renal functions although the bleeding was ceased. Conclusion: Though hepatic arterial hemorrhage occurred after percutaneous transhepatic biliary drainage is a rare complication, it is dangerous and fatal. Hepatic arterial angiography together with interventional embolization is a sate and effective therapy for hepatic arterial hemorrhage. (authors)

    This study was conducted to evaluate the safety and efficacy of ultrasound (US)-guided percutaneous radiofrequency ablation (RFA) for multiple breast fibroadenoma as an alternative to surgical resection. Sixty-five patients with multiple breast fibroadenoma accepted general anesthesia and US-guided percutaneous RFA in our hospital from September 2014 to January 2016. Contrast-enhanced US (CEUS) was used immediately after operation to determine whether the tumor was ablated completely. The complete ablation rate (CAR) and the change of focal volume were evaluated by CEUS at the 1st month and the 3rd month after operation. All the patients were diagnosed by needle biopsy. Among all the patients, 256 nodules were found. Forty-six nodules (17.96%) were located fibroadenoma.

    Percutaneous vertebroplasty (pv) is a worldwide increasingly performed interventional therapeutic procedure. This article addresses indications, patient preparation, technical requirements and approach as well as possible complications of percutaneous vertebroplasty. Percutaneous vertebroplasty is a technique consisting in an injection of bone cement into a vertebral body under imaging guidance. This procedure is performed to relief pain and support the mechanical stability in partially collapsed vertebral bodies. In the management of spinal compression fractures secondary to osteoporosis, myeloma, osteolytic metastases and aggressive hemangiomas, percutaneous vertebroplasty yields analgesic effect, and provides additional fortification in weakened segments of the vertebral column. Contraindications include major bleeding disorders, radicular pain and pain caused by compression of the myelon. Percutaneous vertebroplasty results in prompt pain relief and rapid rehabilitation. In experienced hands, using correct technique, pv is a safe and effective procedure for treating pain, caused either by osteoporotic or malignant vertebral compression fractures. (orig.) [de

    Lung parenchymal abscesses represent an uncommon pathology with high mortality if untreated. Although most respond well to antibiotics, the optimal therapy for persistent abscesses is unknown. The purpose of this study was to review the outcomes of percutaneous lung parenchymal abscess catheter drainage after broad-spectrum antibiotic therapy failure and correlate with patient microbiologic samples. Retrospective review of patients who underwent percutaneous lung abscess drainage at a tertiary hospital system from 2005 to 2015 was performed. In total, 19 procedures were identified on 16 different patients; six females and ten males. Mean patient age was 55 years (range 22-81). Median follow-up time was 7 months (range abscess cavity in 58% (11/19) or with non-draining abscess cavities in 21% (4/19) for a clinical success rate of 79%. Blood cultures demonstrated no growth in all cases, while 21% (4/19) of sputum or bronchoscopic cultures demonstrated growth. In comparison, the specimens from initial catheter placement isolated a causative organism in 95% (18/19) of case (p lung abscess after broad-spectrum antibiotics, percutaneous abscess drainage is highly sensitive for microbiologic sampling compared to sputum/bronchoscopic or blood cultures. Additionally, percutaneous drainage of lung parenchymal abscess cavities may promote resolution of the abscess with high rates of therapeutic success and low complications.

  1. Indications for percutaneous nephrostomy in patients with obstructive uropathy due to malignant urogenital neoplasias

    Frederico R. Romero

    2005-04-01

    Full Text Available INTRODUCTION: Urogenital neoplasias frequently progress with obstructive uropathy due to local spreading or pelvic metastases. The urinary obstruction must be immediately relieved in order to avoid deterioration in these patients. The percutaneous nephrostomy is a safe and effective method for relief the obstruction; however the indications of such procedures have been questioned in patients with poor prognosis. MATERIAL AND METHODS: A retrospective study was performed with 43 patients (29 female and 14 male with urogenital neoplasias who were undergoing percutaneous nephrostomy during a 54-month period. The median age was 52 years. The primary tumoral site was the uterine cervix in 53.5% of patients, the bladder in 23.3%, the prostate in 11.6% and other sites in 11.6%. RESULTS: Postoperative complications occurred in 42.3% of the patients. There was no procedure-related mortality. Thirty-nine per cent of the patients died during the hospitalization period due to advanced neoplasia. The mortality rate was higher in patients with prostate cancer (p = 0.006, in patients over 52 years of age (p = 0.03 and in those who required hemodialysis before the procedure (p = 0.02. Thirty-two per cent of the patients survived long enough to undergo some form of treatment focused on the primary tumor. The survival rate was 40% at 6 months and 24.2% at 12 months. The percentage of the lifetime spent in hospitalization was 17.7%. The survival rate was higher in patients with neoplasia of the uterine cervix (p = 0.007 and in patients with 52 years of age or less (p = 0.008. CONCLUSION: Morbidity was high in this patient group; however, the majority of patients could be discharged from hospital and followed at home. Patients under 52 years of age and patients with neoplasia of the uterine cervix benefited most from the percutaneous nephrostomy when compared to patients with hormone therapy-refractory prostate cancer, bladder cancer or over 52 years of age.

    To investigate clinical efficacy of unstable pelvic fractures in the treatment with percutaneous sacroiliac screws and sacroiliac joint anterior plate fixation. 64 patients with unstable pelvic fractures were selected in the hospital from January 2008 to June 2011, and were randomly divided into two groups.(32 patients with sacroiliac anterior plate fixation as the control group, and another 32 patients with percutaneous sacroiliac screw internal fixation as the observation group). The perioperative period clinical indicators, postoperative Matta score, postoperative Majeed function score of all patients were compared and analyzed. The operation time, intraoperative blood loss, wound total length, postoperative fever time, duration of hospitalization in the observation group were significantly less than those in the control group. The complication rate (3.1%) in the observation group was lower than that in the control group (21.9%). The rate of Matta score excellent (96.9%) in the observation group was higher than that in the control group (81.2%) after the treatment. The rate of Majeed function score excellent (93.8%) in the observation group was significantly higher than that in the control group (75%) after the treatment. Percutaneous sacroiliac screw internal fixation in the treatment of unstable pelvic fractures has less injury, less bleeding, less pain and rapid recovery which is a safe and effective minimally invasive operation method. The clinical curative effect of percutaneous sacroiliac screw internal fixation is better than anterior plate fixation for the treatment of sacroiliac joint. The full preparation before the surgery and patients with positive can substantially reduce the occurrence of complications rate.

    Percutaneous nephrostomy for relief of obstruction and functional preservation of the kidney was effectively performed 19 times in 14 patients for recent 1 year since July 1982 at Department of Radiology in Seoul National University Hospital. The etiologies of the total 14 obstructive uropathies were metastatc cervix cancer in 6-cases, metastatic rectal cancer in 2 cases, and metastatic bladder cancer, malignant mixed mesodermal tumor of perimetrium, pyonephrosis, bilateral staghorn stone, UVJ obstruction of undetermined cause, congenital UPJ obstruction in 1 case respectively. Percutaneous nephrostomy was done bilaterally in 1 case of congenital UPJ obstruction and unilaterally in 13 case. We used ultrasound as puncture guide in 13 cases and computed tomography in 1 case. Major complication was absent, but minor complications occurred in 4 patients: gross hematuria persisting 24 hours (1 case), catheter dislodgment after several weeks (2 cases) and luminal narrowing after 3 months (1 case). Satisfactory outcomes were made in 13 patients except 1 patient who succumbed one day after the procedure due to preexisting severe sepsis. The procedure proved to be safe and effective alternative to operative nephrostomy in some patients with urinary obstruction

    To avoid the radiation injuries and use of contrast agent, we assessed the safety and efficacy of percutaneous patent ductus arteriosus closure solely under thoracic echocardiography guidance. From June 2013 to June 2014, thirty patients (mean age: (6.3 ± 2.5) years, mean body weight:(22.5 ± 7.3) kg) with pure patent ductus arteriosus were continuously included in this study. The mean diameter of patent ductus arteriosus was (3.8 ± 0.9) mm. Patients were all treated by percutaneous patent ductus arteriosus closure via right femoral artery solely under thoracic echocardiography guidance. The efficacy of the procedure was evaluated by thoracic echocardiography. Follow-up was performed at one month after procedure. All 30 cases were successfully treated with percutaneous patent ductus arteriosus closure solely under thracic echocardiography guidance. The procedural time was (32.8 ± 5.7) minutes. The mean diameter of Amplatzer ADO II was (4.9 ± 1.0) mm. Postoperative trivial residual shunt occurred in six patients immediately after the procedure. All patients survived without peripheral vascular injury or complications such as cardiac perforation. Hospitalization time was (3.4 ± 0.7) days. At one-month follow-up, no complications such as residual shunt or pericardial effusion were observed. Echocardiography guided percutaneous patent ductus arteriosus closure by femoral artery approach is safe and effective, and can avoid X-ray and the use of contrast agents.

    To assess the efficacy and safety of a 'mini-perc' technique of percutaneous nephrolithotomy using a 14-Fr peel-away sheath for the removal of pyelocaliceal stones, and to determine appropriate inclusion criteria. Form July 1999 to June 2002, the medical records and radiographic images of 72 patients who underwent the 'mini-perc' technique of percutaneous nephrolithotomy with a 14-Fr peel-away sheath, were reviewed to determine clinical history, stone characteristics, immediate stone free rate, final stone free rate after additional procedures, complications, and hospital stay. We also analyzed the effect of the longest stone diameter, the cumulative longest diameter of stones, the cumulative stone burden, and the stone density on the immediate stone free rate using a Fisher exact test. The only major complication, arterial bleeding, occurred in a patient with Child A liver cirrhosis and was successfully treated by embolization with coils and a gelatin sponge. The immediate stone free rate was 80.6%, which was significantly influenced by stone diameter but not stone density. The mean hospital stay after the procedure was 3.97 days. The 'mini-perc' technique of percutaneous nephrolithotomy, which uses the 14-Fr peel-away sheath, is a safe and effective modality for treating renal calculi

    Screw fixation (osteosynthesis) can be performed percutaneously by interventional radiologists. We report our experience in cancer patients. We retrospectively reviewed all cases of percutaneous osteosynthesis (PO) of the pelvic ring and proximal femur performed in our hospital. PO were performed for fracture palliation or for osteolytic metastases consolidation. Screws were inserted under CT- or cone-beam CT- guidance and general anaesthesia. Patients were followed-up with pelvic-CT and medical consultation at 1 month, then every 3 months. For fractures, the goal was pain palliation and for osteolytic metastases, pathologic fracture prevention. Between February 2010 and August 2014, 64 cancer patients were treated with PO. Twenty-one patients had PO alone for 33 painful fractures (13 bone-insufficiency, 20 pathologic fractures). The pain was significantly improved at 1 month (VAS score = 20/100 vs. 80/100). In addition, 43 cancer patients were preventively consolidated using PO plus cementoplasty for 45 impending pathologic fractures (10 iliac crests, 35 proximal femurs). For the iliac crests, no fracture occurred (median-FU = 75 days). For the proximal femurs, 2 pathological fractures occurred (fracture rate = 5.7 %, median-FU = 205 days). PO is a new tool in the therapeutic arsenal of interventional radiologists for bone pain management. (orig.)

    To introduce a method that can be performed with minimal equipments available to most orthopedic surgeons and precludes the extensive anesthetic and ablative requirements. A percutaneous lead tunnel was first established in the cortex next to the nidus under computerized tomography guidance with local anesthesia; then the nidus was curetted in the operating room through the lead tunnel. The study was performed in Shariati Hospital in Tehran, Iran, from September 2002 to December 2005. Nineteen patients were treated with this method with 94.7% cure rate. The diagnosis was histologically confirmed in 16 cases (84.2%). Failure occurred in one patient. The patients had a mean follow-up of 13.5 months with no recurrence of symptoms with mean hospitalization time of 1.6 days. This technique is simple, minimally invasive and effective. It needs no especial equipments and provides the material for tissue diagnosis. (author)

    The fundamental technique of performing percutaneous cardiovascular (CV) interventions has remained unchanged and requires operators to wear heavy lead aprons to minimize exposure to ionizing radiation. Robotic technology is now being utilized in interventional cardiology partially as a direct result of the increasing appreciation of the long-term occupational hazards of the field. This review was undertaken to report the clinical outcomes of percutaneous robotic coronary and peripheral vascular interventions. Areas covered: A systematic literature review of percutaneous robotic CV interventions was undertaken. The safety and feasibility of percutaneous robotically-assisted CV interventions has been validated in simple to complex coronary disease, and iliofemoral disease. Studies have shown that robotically-assisted PCI significantly reduces operator exposure to harmful ionizing radiation without compromising procedural success or clinical efficacy. In addition to the operator benefits, robotically-assisted intervention has the potential for patient advantages by allowing more accurate lesion length measurement, precise stent placement and lower patient radiation exposure. However, further investigation is required to fully elucidate these potential benefits. Expert commentary: Incremental improvement in robotic technology and telecommunications would enable treatment of an even broader patient population, and potentially provide remote robotic PCI.

    Percutaneous nephrostomy was performed in 82 patients under the fluoroscopic guidance for recent 3 years. The cause of hydronephrosis were as follows: unknown origin of stricture (N=37), stone (N=20), tumor (N=14), tuberculosis (N=8), postoperative ureteral injury (N=1), postoperative anastomotic stricture(N=1)and renal transplantation complication (N=1). Successful nephrostomy was achieved in 79 patients (96%). Causes if failure were minimal dilatation of pelvocaliceal system (N=2) and staghorn calculi (N=1). Follow up laboratory test shows high BUN and creatinine level returned to normal limit within 1 or 3 weeks in 73 patient. Major complication was not found, but temporary hematuria (N=4) or fever (N=1) was noted. In conclusion, percutaneous nephrostomy is the safe and effective method for the temporary and permanent relief of urinary obstruction and maintenance of ureteral patency.

    Complex joint fractures often require an open surgical procedure, which is associated with extensive soft tissue damages and longer hospitalization and rehabilitation time. Percutaneous techniques can potentially mitigate these risks but their application to joint fractures is limited by the current sub-optimal 2D intra-operative imaging (fluoroscopy) and by the high forces involved in the fragment manipulation (due to the presence of soft tissue, e.g., muscles) which might result in fracture malreduction. Integration of robotic assistance and 3D image guidance can potentially overcome these issues. The authors propose an image-guided surgical robotic system for the percutaneous treatment of knee joint fractures, i.e., the robot-assisted fracture surgery (RAFS) system. It allows simultaneous manipulation of two bone fragments, safer robot-bone fixation system, and a traction performing robotic manipulator. This system has led to a novel clinical workflow and has been tested both in laboratory and in clinically relevant cadaveric trials. The RAFS system was tested on 9 cadaver specimens and was able to reduce 7 out of 9 distal femur fractures (T- and Y-shape 33-C1) with acceptable accuracy (≈1 mm, ≈5°), demonstrating its applicability to fix knee joint fractures. This study paved the way to develop novel technologies for percutaneous treatment of complex fractures including hip, ankle, and shoulder, thus representing a step toward minimally-invasive fracture surgeries.

    A total of 6 pregnant women with obstructing urinary calculi was managed by percutaneous nephrostomy drainage placed under ultrasound guidance with the patient under local anesthesia. All patients initially had relief of acute obstruction. However, occlusion of the percutaneous nephrostomy tubes with debris necessitated tube changes in 5 of 6 patients. In 2 patients recurrent nephrostomy tube obstruction, fever and pain led to percutaneous stone removal during pregnancy. In the remaining 4 patients the nephrostomy tubes were left indwelling through delivery. During the postpartum period 3 patients successfully underwent ureteroscopic stone extraction and 1 passed the stone spontaneously. Bacteriuria developed in each patient despite the use of preventive antibiotics. All 6 women had uncomplicated vaginal deliveries of healthy newborns and are currently asymptomatic with no evidence of obstruction. Percutaneous drainage of an acutely obstructed kidney in a pregnant woman is an effective temporizing alternative to ureteral stent placement until definitive treatment can be performed.

    To compare the effectiveness, adverse effects, and cost-effectiveness of percutaneous neurolytic celiac plexus block (NCPB) versus traditional medication strategies for the treatment of patients with advanced cancer having severe upper abdominal cancer pain. This retrospective study included 81 patients with advanced upper abdominal cancer admitted to The Sixth People's Hospital Affiliated to Shanghai Jiaotong University between January 2013 and July 2014. The patients were divided into percutaneous NCPB (treatment) and medication for pain (control) groups. The outcomes were measured in terms of Numeric Rating Scale (NRS) score and Karnofsky Performance Status (KPS) score before treatment and on the 3rd, 7th, 14th, and 28th days posttreatment. The effectiveness and cost-effectiveness of the therapy were assessed using analysis of the health economics. The improvements in NRS score (1.42 ± 1.09 vs 4.03 ± 0.96, P economics evaluation revealed that the medicine-specific costs and total health care costs were significantly reduced in the treatment group compared to the control group ( P .05) were seen in the costs of hospitalization, examinations, and treatment. The percutaneous NCPB method shows promising results and better cost-effectiveness for treating patients with advanced cancer having severe upper abdominal pain.

    To investigate the impact of staghorn stone branch number on outcomes of percutaneous nephrolithotomy (PNL). From January 2009 to January 2013, the 371 patients with staghorn stones who were referred to our hospital for PNL were considered for this study. All calculi were showed with CT 3-dimentional reconstruction (3-DR) imaging. The computerized database of the patients had been reviewed. Our exclusion criterion was patients with congenital renal anomalies, such as horse-shoe and ectopic kidneys. And borderline stones that branched to one major calyx only were also not included. From 3-DR images, the number of stone branching into minor renal calices was recorded. We made "3" as the branch breakdown between groups. And the patients were divided into four groups. The number of percutaneous tract, operative time, staged PNL, intra-operative blood loss, complications, stone clearance rate, and postoperative hospital day were compared. The 371 patients (386 renal units) underwent PNL successfully, included 144 single-tract PNL, 242 multi-tract PNL, 97 staged PNL. The average operative time was (100 ± 50) minutes; the average intra-operative blood loss was (83 ± 67) ml. The stone clearance rate were 61.7% (3 days) and 79.5% (3 months). The postoperative hospital stay was (6.9 ± 3.4) days. A significantly higher ratio of multi-tract (χ(2) = 212.220, P PNL (χ(2) = 49.679, P PNL for calculi with stone branch number ≥ 5. There was no statistically meaningful difference among the 4 groups based on Clavien complication system (P = 0.460). The possibility of multi-tract and staged PNL, lower rate of stone clearance and longer postoperative hospital day increase for staghorn calculi with stone branch number more than 5.

    The aim of this paper was to report outcomes of endovascular aneurysm repair with percutaneous femoral access (pEVAR) using Prostar XL and Proglide closure systems (Abbot Vascular, Santa Clara, CA, USA), from the multicenter Italian Percutaneous EVAR (IPER) registry. Consecutive patients affected by aortic pathology treated by EVAR with percutaneous access (pEVAR) between January 2010 and December 2014 at seven Italian centers were enrolled in this multicenter registry. All the operators had an experience of at least 50 percutaneous femoral access procedures. Data were prospectively collected into a dedicated online database including patient's demographics, anatomical features, intra- and postoperative outcomes. A retrospective analysis was carried out to report intraoperative and 30-day technical success and access-related complication rate. Uni- and multivariate analyses were performed to identify factors potentially associated with an increased risk of percutaneous pEVAR failure. A total of 2381 accesses were collected in 1322 patients, 1249 (94.4%) male with a mean age of 73.5±8.3 years (range 45-97). The overall technical success rate was 96.8% (2305/2381). Major intraoperative access-related complications requiring conversion to surgical cut-down were observed in 3.2% of the cases (76/2381). One-month pEVAR failure-rate was 0.25% (6/2381). Presence of femoral artery calcifications resulted to be a significant predictor of technical failure (OR: 1.69; 95% CI: 1.03-2.77; P=0.036) at multivariate analysis. No significant association was observed with sex (P=0.28), obesity (P=0.64), CFA diameter (P=0.32), level of CFA bifurcation (P=0.94) and sheath size >18 F (P=0.24). The use of Proglide was associated with a lower failure rate compared to Prostar XL (2.5% vs. 3.3%) despite not statistically significant (P=0.33). The results of the IPER registry confirm the high technical success rate of percutaneous EVAR when performed by experienced operators, even in

    To present our experience regarding the feasibility, safety, and efficacy of ultrasound (US)-guided percutaneous nephrolithotomy in anatomically abnormal kidneys. We performed US-guided percutaneous nephrolithotomy in 15 patients with anatomically abnormal kidneys and renal calculi. Of the 15 patients, 5 had horseshoe kidneys, 5 had rotation anomalies, 2 had kyphoscoliosis, and 3 had scoliosis. The stone size, number of access tracts, operative time, hospitalization duration, rate of stone clearance, and complication rate were recorded. Percutaneous access was achieved with US guidance in the operating room by the urologist. Successful renal access was obtained by the surgeon using US guidance in all patients, and a single access was obtained in all cases. Of the 15 patients, 8 were females, and 7 were males; 8 patients had solitary stones, and 7 had multiple calculi. The renal calculi were on the right in 7 patients and on the left in 8. Three patients had previously undergone unsuccessful shock wave lithotripsy. Complete stone clearance was achieved in 13 patients. The mean operative time was 54.2 minutes. No patient required a blood transfusion because of bleeding. Urinary tract infections occurred in 2 patients, who were treated with antibiotics. A double-J catheter was not inserted in any patient; however, a ureteral catheter was used in 3 patients for 1 day. None of the patients had any major complications during the postoperative period. The stone-free rate was 87%, and 2 patients had clinically insignificant residual fragments. Our results have demonstrated that US-guided percutaneous nephrolithotomy can be performed feasibly, safely, and effectively in anatomically abnormal kidneys. Copyright © 2013 Elsevier Inc.

    With the success of percutaneous abdominal abscess drainage, attention is now being focused on the use of similar techniques in the thorax. We studied to evaluate the effect of percutaneous drainage in parenchymal fluid collections in the lungs. We performed percutaneous drainage of abscesses and other parenchymal fluid collections of the lungs in 15 patients. All of the procedures were performed under the fluoroscopic guidance with an 18-gauge Seldinger needle and coaxial technique with a 8-10F drainage catheter. Among 10 patients with lung abscess, 8 patients improved by percutaneous catheter drainage. In one patient, drainage was failed by the accidental withdrawal of the catheter before complete drainage. One patient died of sepsis 5 hours after the procedure. Among three patients with complicated bulla, successful drainage was done in two patients, but in the remaining patient, the procedure was failed. In one patient with intrapulmonary bronchogenic cyst, the drainage was not successful due to the thick internal contents. In one patient with traumatic hematoma, after the drainage of old blood clots, the signs of infection disappeared. Overally, of 14 patients excluding one who died, 11 patients improved with percutaneous catheter drainage and three patients did not. There were no major complications during and after the procedure. We conclude that percutaneous catheter drainage is effective and safe procedure for the treatment of parenchymal fluid collections of the lung in patients unresponsive to the medical treatment

    To report the feasibility and long-term clinical outcome of percutaneous aspiration thrombectomy for treating acute or subacute arterial thromboembolism in the infrainguinal arteries. Thirty limbs of 29 patients were enrolled in this retrospective study between January 2004 and March 2014. Nine limbs underwent overnight catheter-directed thrombolysis followed by percutaneous aspiration thrombectomy (PAT). Eighteen limbs underwent PAT with adjunctive selective intra-arterial thrombolysis in a single session. The remaining three limbs underwent PAT alone. Balloon angioplasty (n = 16) or stent placement (n = 3) was performed as required. In-hospital mortality and complications were estimated. The primary patency rate and the rate of freedom from reintervention were calculated using the Kaplan-Meier method. Technical success was achieved in 28 limbs. Clinical success was achieved in 27 limbs. The mean ankle-brachial index increased from 0.17 ± 0.26 to 0.98 ± 0.19 after the procedure. Three in-hospital deaths and no major amputations were recorded. Distal embolization of crural arteries occurred as a minor complication in five limbs, but no major complications occurred. The primary patency rate and the rate of freedom from reintervention were 74.9% and 90.9% at 1 year, respectively, and 66.6% and 80.8% at 2 years, respectively. PAT is a rapid and effective method to remove a thrombus from occluded infrainguinal arteries.

    Treatment of large renal stones has changed considerably in recent years. The increasing prevalence of nephrolithiasis has mandated that urologists perform more surgeries for large renal calculi than before, and this has been met with improvements in percutaneous stone surgery. In this review paper, we examine recent developments in percutaneous stone surgery, including advances in diagnosis and preoperative planning, renal access, patient position, tract dilation, nephroscopes, lithotripsy, exit strategies, and post-operative antibiotic prophylaxis.

    The recurrence of pediatric nephrolithiasis, the morbidity of repeated open surgical treatment as well as our experience in percutaneous nephrolithotomy (PNL) in adult patients, all derived us to shift to PNL for managing renal stones >1.5 cm in pediatric patients. Our aim of this study is to evaluate the safety and efficacy of PNL in pediatric patients. During the period of the month between May 2011 and April 2013, 38 children (47 renal units) underwent PNL for renal stones 1.5-5 cm in length. Patient demographics, stone characteristics, and clinical outcome were prospectively studied. Data of those who underwent conventional and tubeless PNL were compared. Median follow-up period was 12 months (range: 6-24). The median age at presentation was 8-year (range: 3-12). The operative time ranged from 30 to 120 min (median 90). Overall stone clearance rate was 91.5% after single PNL. The median hospital stay was 3 days. Auxiliary procedures were successful for the remaining 4 patients (nephroscopic clearance in one and shockwave lithotripsy in 3). Tubeless PNL was performed in 17 renal units with a comparable outcome to conventional ones. The perioperative complications were noted in 5/47 (10.6%) of all procedures (Clavien Grade II in 4 and Clavien Grade IIIa in 1) and were managed conservatively. Percutaneous nephrolithotomy for renal stones in pediatric patients is safe and feasible if performed by a well-experienced endourologist. Tubeless PNL is a better choice for children.

    Background. Invasive pulmonary aspergillosis is fulminant and often fatal in immunosuppressed patients. Percutaneous biopsy may select patients who could benefit from surgical resection. Objective. We sought to determine the accuracy of percutaneous biopsy for pediatric invasive pulmonary aspergillosis. Materials and methods. We retrospectively reviewed 28 imaging-guided percutaneous biopsies of the lungs of 24 children with suspected pulmonary aspergillosis. Twenty-two were being treated for malignancy and two for congenital immunodeficiency; 15 had received bone-marrow transplants. The accuracy of the percutaneous lung biopsy was determined by subsequent surgical resection, autopsy, or clinical course. Results. Histopathological studies showed ten biopsy specimens with septate hyphae, indicating a mold, and seven with Aspergillus flavus colonies in culture. The remaining 18 biopsies revealed no fungi. No patient had progressive aspergillosis after negative biopsy. Invasive pulmonary mold was detected by percutaneous biopsy with 100 % (10/10) sensitivity and 100 % (18/18) specificity. Percutaneous biopsy results influenced the surgical decision in 86 % (24 of 28) of the cases. Bleeding complicated the biopsy in 46 % (13/28) and hastened one death. Conclusion. Percutaneous biopsy of the lung is an accurate technique for the diagnosis of invasive pulmonary aspergillosis and correctly determines which immunosuppressed pediatric patients would benefit from therapeutic pulmonary resection.

    We evaluated percutaneous nephrostomy for adult kidneys with severe hydronephrosis due to ureteropelvic junction obstruction and less than 10% split renal function. In this retrospective analysis we included patients who underwent percutaneous nephrostomy for unilateral ureteropelvic junction obstruction of the kidneys with hydronephrosis and less than 10% split renal function at our hospital between May 2009 and January 2012. Adults (age 18 years or greater) were divided into those 35 years or younger (young adults) and older than 35 years (older adults). The percutaneous nephrostomy remained in situ a mean ± SD of 6.62 ± 2.55 weeks and patients underwent repeat renography before pyeloplasty. When there was no significant improvement in split renal function (10% or greater) and drainage (greater than 400 ml per day), nephrectomy was performed. Otherwise pyeloplasty was performed. Patients were followed by renography, ultrasound and contrast computerized tomography at 3 and 6 months, at 1 year and annually thereafter. Of 53 patients 30 (56.6%) showed improvement after percutaneous nephrostomy drainage and urine output greater than 400 ml per day with percutaneous nephrostomy. Pyeloplasty was then performed. Of 29 young adults 24 (82.8%) showed improved split renal function vs 6 of 24 older adults (25%). Nephrectomy of the other 23 kidneys was performed. At a mean followup of 19.27 ± 7.82 months (range 12 to 36), no patient showed hypertension or urinary tract infection. Split renal function detected by renography may not accurately predict recovered, poorly functioning kidneys, especially in young adults. First observing the recoverability of hydronephrotic kidneys by percutaneous nephrostomy drainage and then preserving select kidneys may be an effective method to manage poorly functioning kidneys due to ureteropelvic junction obstruction.

    Percutaneous radiofrequency (RF) rhizotomy of the medial branches of the dorsal rami from the spinal nerves is the standard treatment for cervical zygapophyseal joint mediated pain. There is a paucity of data regarding the longevity of analgesia following this procedure. To determine the duration of complete pain relief, analgesic consumption and any adverse events following percutaneous cervical RF rhizotomy. Retrospective chart review of patients who had undergone percutaneous cervical RF rhizotomy for zygapophyseal joint mediated neck pain. Patient reviews were undertaken by the pain consultant at 6 weeks, 6 months and 1 year following the procedure. Where follow-up was incomplete, the patient was assumed only to have had pain relief until their last review where complete pain relief had been documented. Analgesic consumption and any adverse events were recorded. The data was analysed using Microsoft Excel®. At 12 months 63.64% of patients were pain free. Median duration of complete pain relief was 52 weeks. Patients who experienced pain relief had ceased using prescription analgesia by their 6 week review. There were no repeat cervical RF rhizotomies, procedure related infections or unplanned hospital admissions. Percutaneous cervical RF rhizotomy is an effective treatment for cervical zygapophyseal joint mediated neck pain.

    To determine the impact of staghorn calculi branch number on outcomes of percutaneous nephrolithotomy (PNL). Retrospectively, we evaluated 371 patients (386 renal units) who underwent PNL for staghorn calculi. All calculi were showed with CT three-dimensional reconstruction (3DR) imaging preoperatively. From 3DR images, the number of stone branching into minor renal calices was recorded. According to the number, patients were divided into four groups. Group 1: the branch number 2-4; Group 2: the branch number 5-7; Group 3: the branch number 8-10; Group 4: the branch number >10. The number of percutaneous tract, operative time, staged PNL, intraoperative blood loss, postoperative hospital stay, complications, main stone composition, and stone clearance rate were compared. A significantly higher ratio of multitract (pPNL (pPNL for calculi with a stone branch number ≥5. There was no statistical difference in intraoperative blood loss (p=0.101) and main stone composition (p=0.546). There was no statistically meaningful difference among the four groups based on the Clavien complication system (p=0.46). With the stone branch number more than five, the possibility of multitract and staged PNL, lower rate of stone clearance, and a longer postoperative hospital stay increases for staghorn calculi.

    Aim: The objective of this study is to evaluate the efficacy and safety of image-guided percutaneous splenic interventions as diagnostic or therapeutic procedures. Materials and methods: We performed a retrospective review of our interventional records from July 2001 to June 2006. Ninety-five image-guided percutaneous splenic interventions were performed after informed consent in 89 patients: 64 men and 25 women who ranged in age from 5 months to 71 years (mean, 38.4 years) under ultrasound (n = 93) or CT (n = 2) guidance. The procedures performed were fine needle aspiration biopsy of focal splenic lesions (n = 78) and aspiration (n = 10) or percutaneous catheter drainage of a splenic abscess (n = 7). Results: Splenic fine needle aspiration biopsy was successful in 62 (83.78%) of 74 patients with benign lesions diagnosed in 43 (58.1%) and malignancy in 19 (25.67%) patients. The most common pathologies included tuberculosis (26 patients, 35.13%) and lymphoma (14 patients, 18.91%). Therapeutic aspiration or pigtail catheter drainage was successful in all (100%) patients. There were no major complications. Conclusions: Image-guided splenic fine needle aspiration biopsy is a safe and accurate technique that can provide a definitive diagnosis in most patients with focal lesions in the spleen. This study also suggests that image-guided percutaneous aspiration or catheter drainage of splenic abscesses is a safe and effective alternative to surgery

    Although not directly responsible for patient care, hospital housekeepers are still susceptible to accidents with biological material. The objectives of this study were to establish profile and frequency of accidents among hospital housekeepers, describe behaviors pre- and postaccident, and risk factors. This was a cross-sectional study with hospital housekeepers in Goiania, Brazil. Data were obtained from interviews and vaccination records. The observations were as follows: (1) participating workers: 94.3%; (2) incomplete hepatitis B vaccination: 1 in 3; and (3) accident rate: 26.5%, mostly percutaneous with hypodermic needles, and involved blood from an unknown source; roughly half occurred during waste management. Upon review, length of service less than 5 years, completed hepatitis B vaccination, and had been tested for anti-HBs (hepatitis B surface antigen) influenced frequency of accidents. These findings suggest that improper disposal of waste appears to enhance the risk to hospital housekeepers. All hospital workers should receive continued training with regard to waste management.

Changes seen in revascularization techniques have been numerous. The rapid evolution of evidence-based revascularization procedures has occurred as a result of many pivotal large randomized clinical trials. Objective: This review compares and contrasts outcomes from two coronary revascularization techniques, coronary artery bypass grafting (CABG and PCI, with particular reference to the landmark trials that inform practice guidelines. Methods: We undertook a comprehensive review of published literature addressing trials in this field performed to address current knowledge both in the predrug-eluting stent and postdrug-eluting stent era. Results and discussion: Surgical and percutaneous revascularization strategies have different strengths and weaknesses, and neither strategy is superior in all patients, clinical presentations, or anatomical subgroups. Current data support the use of percutaneous intervention in ST elevation myocardial infarction and in single-vessel disease. In noncomplex multivessel disease and isolated left main stem PCI, the data support non-inferiority of PCI compared to CABG as reflected in the 2014 European Society of Cardiology guidelines. Landmark revascularization trials of multivessel disease comparing CABG to PCI found no survival benefit to CABG over PCI, except in patients with complex disease. In these trials, revascularization drove differences in primary endpoints and in all but the

    Catheter based treatment has gained wide acceptance for management of patent ductus arteriosus (PDA) ever since its introduction. Percutaneous closure in adults can be challenging because of anatomical factors including large sizes, associated pulmonary arterial hypertension (PAH) and co-morbidities. This study aimed to provide comprehensive contemporary data on the safety and efficacy of percutaneous device closure of PDA in adult and adolescent population at a large referral center. This single-center retrospective analysis included 70 patients (33 adolescents and 37 adults) who underwent successful percutaneous device closure of PDA between January 2011 and February 2017.Baseline patient demographics, clinical characteristics, procedural and device related variables, and immediate outcomes during hospital stay were recorded. Patients were followed up for residual shunt and complications. Of 70 PDA device closure cases, 71.4% were females; the mean age was 23 years (range:10-58years). Devices used were 4-Cook's detachable coils, 64-occluders (ADO-I and II, Lifetech, Cardi-O-Fix), 1-vascular plug and 1-ventricular septal occluder device. Device success was achieved in all including those with very large PDAs. At 24-h post-procedure, the success rate of transcatheter intervention was 95.7%. At 6-months follow up, complete closure was observed in all (mean follow up duration-531days). In patients with severe PAH, significant immediate and sustained reduction of the mean pulmonary pressure was observed(77mmHg to 33mmHg;P=0.014). No procedure-related complications including death, device embolization and stenosis of aorta or pulmonary artery occurred. In contemporary practice, percutaneous device closure is an effective and safe treatment option for adolescent and adult PDA patients. Copyright © 2017. Published by Elsevier B.V.

    The new techniques for an early treatement of acute myocardial infarction (AMI), such as thrombolysis and percutaneous transluminal angioplasty, often necessitate rapid and accurate radiological evaluation of coronaric lesions and left ventricular function. The aim of the present study was to evaluate both safety and tolerability of selective coronarography (SC) and left ventriculography (LVG), with iopamidol 370 mg I/ml as a contrast medium, in the acute phase of AMI. Thirty-nine patients aged 26-29 years, were examined: 18 group A, within 4 days (mean 2.6+-0.8 SD) and 21, group B, within 5-15 days after AMI (mean 8.8+-3 SD). Contrast media (cm) dosage varied from 150 to 300 ml (2.43-5.5 ml/bw). During the procedure, ECG was continuosly recorded; left ventricular pressure was registered immediately and 30 minutes after cm administration. During the following 9 days ECG tracings and plasmatic cytolysisenzymes were monitored. During the examination no patient complained of any symptoms. After LVG slight elevations in end diastolic pressure were detected in all patients (mean increase 4.7 mmHg), which were not relevant from a clinical point of view. In 11/39 cases ventricular tachycardia was observed, which spontaneously ceased. During SC no change in ECG tracings was registered except in one patient, group A, in whom complete transitory heart block was detected. After SC no alteration in instrumental and biochemical parameters was registered except in one patient, group B, in whom a reinfarction due to right coronaric artery occlusion was observed. In conclusion, these results suggest that both SC and LVG with iopamidol are safe techniques also in the early phase of myocardial infarction. 24 refs.

    Changes in the skin that occur in the elderly may put them at increased risk for altered percutaneous penetration from pharmacotherapy along with potential adverse effects. Skin factors that may have a role in age-related percutaneous penetration include blood flow, pH, skin thickness, hair and pore density, and the content and structure of proteins, glycosaminoglycans (GAGs), water, and lipids. Each factor is examined as a function of increasing age along with its potential impact on percutaneous penetration. Additionally, topical drugs that successfully overcome the barrier function of the skin can still fall victim to cutaneous metabolism, thereby producing metabolites that may have increased or decreased activity. This overview discusses the current data and highlights the importance of further studies to evaluate the impact of skin factors in age-related percutaneous penetration.

    Randomized trials have demonstrated that primary angioplasty is moreeffective than intravenous thrombolysis in reducing mortality and morbidityin patients with acute myocardial infarction (AMI). The aim of this study wasto assess the in-hospital mortality of patients with AMI admitted to the onlytertiary care center in Kosovo, where coronary percutaneous interventionprocedures are unavailable. We also assessed the impact of age and gender onin-hospital mortality. Consecutive patients with the diagnosis of AMI,admitted in our institution between 1999 and 2007, were included in thisretrospective study. Of 2848 patients (mean age 61+- 1.3 years, 73.4% males)admitted with AMI, 292 (10.25%) died during in-hospital stay. The overallin-hospital mortality was 12.3% for women and 9.5% for men (P<05). Women weresignificantly older than men (64.2+-11 years vs. 59.7+-11.8 years, P<.05).Mean length of stay was 12.0+-94 for women and 10.7+-7.6 for men. From 1999break was detected by the application of thepatients with Ami but themortality rate remained stable. Compared to developed countries, patientswith AMI in Kososvo present at an early age but have a higher mortality rate.Women with AMI had a significantly higher in-hospital mortality rate thanmen. The lack of percutaneous coronary intervention procedures in AMIpatients may have contributed to the high in-hospital mortality in ourpopulation. (auhor)

    Full Text Available Rectus sheath hematoma (RSH is an uncommon cause of abdominal pain that can lead to life-threatening bleeding, particularly in elderly patients receiving anticoagulation therapy. Type III RSHs, based on computer tomography (CT evaluation, is characterized by active bleeding with intramuscular or intraperitoneal extension and hemodynamic instability. Medical contemporary knowledge of this condition is contentious and overall 20% of acute mortality has been reported. The purpose of this study was to retrospectively review our experience and outcomes in the management of RSHs treated with percutaneous arterial embolization of the epigastric vessels. We retrospectively analyzed 43 patients with RSH type III, submitted to percutaneous epigastric artery embolization from 2007 to 2015. Percutaneous arterial embolization was feasible and successful in patients with a high burden of comorbidities and receiving anticoagulation therapy. There was no acute mortality and a late mortality at 3 months of 9.1% (4/43 was not directly related to RSHs or arterial embolization. Patients with late mortality had lower ejection fraction, prolonged PTT, greater RDW and warfarin in overlapping with low-molecular-weight heparins. Transcatheter arterial embolization of the epigastric vessels was safe, feasible and effective in stopping the bleeding. Despite anti-platelets/anti-coagulation therapy and a high burden of comorbidities, there was no acute mortality related to RSH.

    Culture positivity of percutaneous aspiration material" is not included in the current bacteriological criteria for diagnosis of pulmonary nontuberculous mycobacterial (NTM) diseases, which were published by the Infectious Diseases Society of America (IDSA)/American Thoracic Society (ATS) in 2007 or those released by the Japanese Society for Tuberculosis in 2008. However, percutaneous aspiration is a reliable technique for the detection of causative microorganisms isolated from the focus of infection. We discuss the benefits of including positive culture of percutaneous aspiration material in the bacteriological diagnostic criteria of pulmonary NTM diseases. We reviewed the radiological images and clinical courses of pulmonary diseases in which NTM cultures were obtained from percutaneously aspirated materials at our hospital from 1991 to 2011. Aspiration was carried out under local anesthesia, usually with fluoroscopic guidance. After percutaneous insertion of a 22-gauge needle attached to a 20-mL syringe containing about 3 mL of saline, the lesion specimen was withdrawn together with the saline. After the needle was pulled out, the aspirated material and saline were transferred to test tubes for cytological and microbiological examinations. In patients with thin-walled cavitary lesions, saline was injected into the cavity and then aspirated. Percutaneous aspiration was performed in 2,742 patients and NTM disease was detected in 51 patients. Of these 51 patients, 12 had solitary nodular lesions, and in many of these patients, no NTM bacilli could be detected in the sputa or bronchial washing specimens. Mycobacterium avium was identified in 10 of the 12 cases. Four of these 10 patients were followed up after their diagnosis without any treatment: 3 showed spontaneous reduction in lesion size, while 1 patient's condition remained unchanged. Four of the remaining 6 cases were treated with anti-NTM medications, and lesion size reduced in 2 cases, while no change or

    Amyotrophic Lateral Sclerosis (ALS) is a degenerative disorder that affects the pyramidal tract, producing progressive motor dysfunctions leading to paralysis. These patients can present with dysphagia, requiring nutritional support with a nasogastric tube or Percutaneous Endoscopic Gastrostomy (PEG). PEG is associated with increased survival rates. However, the timing of PEG placement remains a significant issue for clinicians. To analyse the characteristics of ALS patients at the moment of PEG placement and their progression. Descriptive retrospective study including patients diagnosed with ALS and PEG who were assessed during the 2005-2014 period in our hospital. Nutritional parameters and respiratory function were assessed for all patients, as well as their progression. The data was analysed using SPSS15. 37 patients were included (56.8% men, 43.2% women) with an average age of 60 at diagnosis, and an average age of 63.1 at PEG placement. 48.6% started with spinal affection and 51.4%, with bulbar affection. 43.2% of the patients received oral nutritional supplements prior to PEG placement for a mean period of 11.3 months. The mean forced vital capacity at diagnosis was 65.45±13.67%, with a negative progression up to 39.47±14.69% at the moment of PEG placement. 86.5% of patients required non-invasive positive-pressure ventilation. 86.5% presented with dysphagia, 64.9% with weight loss > 5-10% from their usual weight, 8.1% with low Body Mass Index, 27% with malnutrition and 73% with aworsened breathing function; therefore, 100% met the criteria for PEG placement according to our protocol. The period on enteral feeding was extended for 10.1 months with a mortality of 50% during the first 6 months from PEG placement. There is evidence of a 3-year delay between diagnosis and PEG placement, with a survival rate of 50% at 6 months from PEG insertion. Further studies are required to establish whether an earlier placement might increase survival rates. Copyright AULA

    Several recent studies have reported the benefits of tubeless percutaneous nephrolithotomy (PNL). Postoperatively, tubeless PNL patients have an indwelling ureteral stent placed, which is often associated with stent-related morbidity. We have performed totally tubeless (tubeless and stentless) PNL in which no nephrostomy tube or ureteral stent is placed postoperatively. We evaluated the safety, effectiveness, and feasibility of totally tubeless PNL. From March 2008 to February 2012, 57 selected patients underwent standard or totally tubeless PNL. Neither a nephrostomy tube nor a ureteral stent was placed in the totally tubeless PNL group. We compared patient and stone characteristics, operation time, length of hospitalization, analgesia requirements, stone-free rate, blood loss, change in creatinine, and perioperative complications between the standard and totally tubeless PNL groups. There were no significant differences in preoperative patient characteristics, postoperative complications, or the stone-free rate between the two groups, but the totally tubeless PNL group showed a shorter hospitalization and a lesser analgesic requirement compared with the standard PNL group. Blood loss and change in creatinine were not significantly different between the two groups. Totally tubeless PNL appears to be a safe and effective alternative for the management of renal stone patients and is associated with a decrease in length of hospital stay.

    Percutaneous radiologic gastrostomy is a well-described method that has not been widely adopted by radiologists. The authors reviewed their experience to highlight technical points and clinical results. Direct percutaneous gastrostomy was performed in 51 patients and percutaneous jejunostomy in four. Indications for gastrostomy procedures were the need for general nutrition (n = 31), complications of use of a nasogastric feeding tube (n = 7), gastric or small bowel decompression (n = 4) and endoscopic failure (n = 5). The major indication for percutaneous jejunostomy was decompression of small bowel obstruction. Key technical aspects include the use of a novel needle device that tacks the abdominal wall to the stomach, thus assuring a seal between the two structures. In the percutaneous gastrostomies, 18-F Foley catheters were introduced through the tacked portion of the stomach with a Seldinger technique and dilators. For percutaneous jejunostomy, 18-F feeding tubes were placed. All procedures were performed under local anesthesia. The authors conclude that a radiologic percutaneous gastrostomy is a safe and effective procedure and should be pursued aggressively by interventional radiologists

    Various methods of peritoneal dialysis (PD) catheter insertion are available. The purpose of this study was to evaluate a percutaneous insertion technique using ultrasound (US) and fluoroscopy performed under conscious sedation and as day case procedure. Data of 87 percutaneous inserted dialysis catheters were prospectively collected, including patients' age, gender, body mass index, history of previous abdominal surgery and cause of end stage renal failure. Length of hospital stay, early complications and time to first use were also recorded. Institutional review board approval was obtained. A 100% technical success rate was observed. Early complications included bleeding (n = 3), catheter dysfunction (n = 6), exit site infection (n = 1) and exit site leakage (n = 1). All cases of catheter dysfunction and one case of bleeding required surgical revision. Median time of follow-up was 18 months (range 3–35), and median time from insertion to first use was days 14 (1–47). Of the 82 patients who started dialysis, 20 (23%) ceased PD at some stage during follow-up. Most frequently encountered reasons include deteriorating patient cognitive or functional status (n = 5), successful transplant kidney (n = 4) and pleuro-peritoneal fistula (n = 4). Sixty-two (71%) PD catheter insertions were performed as day case. The remaining insertions were performed on patients already admitted to the hospital. Percutaneous insertion of dialysis catheter using US and fluoroscopy is not only safe but can be performed as day case procedure in most patients, even with a medical history of abdominal surgery and/or obesity.

Although most respond well to antibiotics, the optimal therapy for persistent abscesses is unknown. The purpose of this study was to review the outcomes of percutaneous lung parenchymal abscess catheter drainage after broad-spectrum antibiotic therapy failure and correlate with patient microbiologic samples.Materials and MethodsRetrospective review of patients who underwent percutaneous lung abscess drainage at a tertiary hospital system from 2005 to 2015 was performed. In total, 19 procedures were identified on 16 different patients; six females and ten males. Mean patient age was 55 years (range 22–81). Median follow-up time was 7 months (range <1–78).ResultsTechnical success was 100%. There was one major complication, a pneumothorax. Follow-up was until tube removal or death in 100% of patients. Catheters were removed with resolution of the abscess cavity in 58% (11/19) or with non-draining abscess cavities in 21% (4/19) for a clinical success rate of 79%. Blood cultures demonstrated no growth in all cases, while 21% (4/19) of sputum or bronchoscopic cultures demonstrated growth. In comparison, the specimens from initial catheter placement isolated a causative organism in 95% (18/19) of case (p < 0.0001).ConclusionIn cases of persistent lung abscess after broad-spectrum antibiotics, percutaneous abscess drainage is highly sensitive for microbiologic sampling compared to sputum/bronchoscopic or blood cultures. Additionally, percutaneous drainage of lung parenchymal abscess cavities may promote resolution of the abscess with high rates of therapeutic success and low complications.

    The purpose of this study was to compare on the basis of up to date papers currently applied methods of the percutaneous tracheostomy (PT). There are four main PT methods by: Ciaglia, Schachner, Griggs and Fantoni. In these methods a wire is introduced into the trachea serving as a guide for special forceps or series of dilatators of increasing diameter to dilate the wall and allow cannulation of the trachea. In the literature authors found a low incidence of complications after PT. Acute complications were documented in 6-18% and late complications in 1-3% of the patients. Follow-up showed no late obstructive complications at the level of stomia and very low (0.3-0.36%) mortality risk. Translaryngeal tracheostomy (TLT) by Fantoni ensures minimal risk of complications and tissue trauma. In the TLT method through a needle inserted in to the trachea a guide wire is retrogradely pushed out of the mouth and attached to special flexible tracheostomy tube by flexible plastic cone with pointed metal tip. This device is then pulled back through larynx and outwards across the trachea and neck wall by traction on the wire. TLT can also be used in infants and children and in difficult patients in whom other techniques are riskier Review of the literature suggests that the PT can be safe and also cost-effective for properly selected patients in intensive care and other hospital units.

    To determine the ability of simple hemodynamic parameters obtained at the time of cardiac catheterization to predict in-hospital mortality following ST-elevation myocardial infarction (STEMI). Hemodynamic parameters measured at the time of primary percutaneous coronary intervention (PPCI) could potentially identify high-risk patients who would benefit from aggressive hemodynamic support in the Cardiac Catheterization laboratory. This is a retrospective single-center study of 219 consecutive patients with STEMI. Left ventricular end-diastolic pressure (LVEDP), systolic blood pressure (SBP), and aortic diastolic blood pressure were obtained after successful revascularization. The prognostic ability of LVEDP, pulse pressure, and SBP/LVEDP ratio were compared to major mortality risk scores. Patients had a mean age of 60 ±14 years, were predominantly white (73%), male (64%), with anterior wall infarcts in 39%. Comorbidities included diabetes mellitus (27%), heart failure (9%), and chronic kidney disease (7%). In-hospital mortality was 9%. Patients with SBP/LVEDP ≤ 4 had increased risk of in-hospital death (32% vs. 5.3%, P  4. The area under curve (AUC) for SBP/LVEDP ratio for in-hospital mortality (0.69) was more predictive than LVEDP (0.61, P = 0.04) or pulse pressure (0.55, P = 0.02) but similar to Shock Index (ratio of heart rate to SBP) and Modified Shock Index (ratio of HR to mean arterial pressure). An SBP/LVEDP ratio ≤ 4 identified a group of STEMI patients at high risk of in-hospital death. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    A perspective study was carried out to assess the efficacy of a combination of percutaneous aspiration plus oral albendazole to assess its efficacy as an alternative to surgery in the treatment of hydatid cyst. We performed percutaneous aspiration followed by injection of 20% hypertonic saline solution into 16 hydatid cysts in 13 patients. All the patients received oral albendazole (400 mg/12 hours) starting 2 days before and lasting until there weeks after the procedure. There were no anaphylactic reactions during or after the procedure. Follow-up included monthly ultrasound over a period ranging between 10 and 36 months. Three cysts disappeared completely; in 10 cases, the cysts cavity was replaced by a complex ultrasonographic findings, with strong signals similar to those of a pseudotumor. In another case, the aspirate was sterile and its morphology remained unchanged. In two cases, infection of the cyst ensued, requiring surgical treatment. We consider that percutaneous aspiration in combination with albendazole may prove to be a good alternative to surgery for the management of hepatic hydatid disease. (Author) 15 refs

    Objective: To evaluate the practicability and safety of the percutaneous transbrachial approach (TBA) for diagnostic coronary angiography and therapeutic percutaneous coronary interventions. Study Design: Quasi experimental study. Place and Duration of Study: The study was carried out in Armed Forces Institute of Cardiology- National Institute of Heart Diseases (AFIC-NIHD) from March 2009 to May 2011. Patients and Methods: We collected data of 100 consecutive patients who underwent coronary catheterization by the percutaneous transbrachial approach. Transbrachial catheterization was performed only if the radial access failed or radial pulse was feeble. Study endpoints included successful brachial artery catheterization, vascular and neurological complications at access site and procedure success rate. Results: Mean age of the patients was 54 years (range 33-79 yrs) and 65(65%) were males and 35 (35%) were females. The right brachial artery was used in all of the cases. Procedural success was achieved in 100% of the patients. Coronary angiography was performed in 70 patients and percutaneous coronary interventions were done in 30 cases. Out of these 30 cases, PCI to left coronary arteries (LAD and LCX) were performed in 19 patients while 11 patients had PCI to right coronary artery (RCA). No case of vascular complications such as major access site bleeding, vascular perforation, brachial artery occlusion causing forearm ischemia, compartment syndrome, vascular spasm or failure to catheterize coronary arteries requiring alternate vascular access were observed. Conclusion: Brachial artery is a safe and easily accessible approach for coronary angiography and percutaneous coronary interventions. (author)

    Policies to reduce unnecessary hospitalizations after percutaneous coronary intervention (PCI) are intended to improve healthcare value by reducing costs while maintaining patient outcomes. Whether facility-level hospitalization rates after PCI are associated with cost of care is unknown. We studied 32,080 patients who received PCI at any 1 of 62 Veterans Affairs hospitals from 2008 to 2011. We identified facility outliers for 30-day risk-standardized hospitalization, mortality, and cost. Compared with the risk-standardized average, 2 hospitals (3.2%) had a lower-than-expected hospitalization rate, and 2 hospitals (3.2%) had a higher-than-expected hospitalization rate. We observed no statistically significant variation in facility-level risk-standardized mortality. The facility-level unadjusted median per patient 30-day total cost was $23,820 (interquartile range, $19,604-$29,958). Compared with the risk-standardized average, 17 hospitals (27.4%) had lower-than-expected costs, and 14 hospitals (22.6%) had higher-than-expected costs. At the facility level, the index PCI accounted for 83.1% of the total cost (range, 60.3%-92.2%), whereas hospitalization after PCI accounted for only 5.8% (range, 2.0%-12.7%) of the 30-day total cost. Facilities with higher hospitalization rates were not more expensive (Spearman ρ=0.16; 95% confidence interval, -0.09 to 0.39; P=0.21). In this national study, hospitalizations in the 30 day after PCI accounted for only 5.8% of 30-day cost, and facility-level cost was not correlated with hospitalization rates. This challenges the focus on reducing hospitalizations after PCI as an effective means of improving healthcare value. Opportunities remain to improve PCI value by reducing the variation in total cost of PCI without compromising patient outcomes. © 2015 American Heart Association, Inc.

    Lung abscess was successfully treated with percutaneous drainage in 5 of 6 patients. Complete abscess resolution occurred in 4 patients, partial resolution in one, and no response in one. The duration of drainage ranged from 7 to 18 days (mean 15.5 days) in successful cases. The failure of drainage in one neurologicall impaired patient was attributed to persistent aspiration. In 2 patients, concurrent pleural empyema was also cured. CT provided the anatomic details necessary for choosing the puncture site and avoiding puncture of the lung parenchyma. Percutaneous catheter drainage is a safe and effective method for treating lung abscess. (orig.).

    The purpose of this study was to examine the immediate and midterm outcomes of percutaneous endovascular repair of thoracic and abdominal aortic pathology. Between December 2003 and June 2005, 21 patients (mean age: 60.4 ± 17.1 years; 15 males, 6 females) underwent endovascular stent-graft insertion for thoracic (n = 13) or abdominal aortic (n = 8) pathology. Preprocedural computed tomographic angiography (CTA) was performed to assess the suitability of aorto-iliac and common femoral artery (CFA) anatomy, including the degree of CFA calcification, for total percutaneous aortic stent-graft repair. Percutaneous access was used for the introduction of 18- to 26-Fr delivery devices. A 'preclose' closure technique using two Perclose suture devices (Perclose A-T; Abbott Vascular) was used in all cases. Data were prospectively collected. Each CFA puncture site was assessed via clinical examination and CTA at 1, 6, and 12 months, followed by annual review thereafter. Minimum follow-up was 36 months. Outcome measures evaluated were rates of technical success, conversion to open surgical repair, complications, and late incidence of arterial stenosis at the site of Perclose suture deployment. A total of 58 Perclose devices were used to close 29 femoral arteriotomies. Outer diameters of stent-graft delivery devices used were 18 Fr (n = 5), 20 Fr (n = 3), 22 Fr (n = 4), 24 Fr (n = 15), and 26 Fr (n = 2). Percutaneous closure was successful in 96.6% (28/29) of arteriotomies. Conversion to surgical repair was required at one access site (3.4%). Mean follow-up was 50 ± 8 months. No late complications were observed. By CT criteria, no patient developed a >50% reduction in CFA caliber at the site of Perclose deployment during the study period. In conclusion, percutaneous aortic stent-graft insertion can be safely performed, with a low risk of both immediate and midterm access-related complications.

    Purpose: To evaluate the efficacy of percutaneous drainage of fluid collections following pancreaticoduodenectomy (Whipple's procedure). Methods: We performed a retrospective review of 19 patients referred to our service with fluid collections following pancreaticoduodenectomy. The presence of associated enteric or biliary fistulas, the route(s) of access for image-guided drainage, the incidence of positive bacterial cultures, and the duration and success of percutaneous management were recorded. Results: Fistulous communication to the jejunum in the region of the pancreatico-jejunal anastomosis was demonstrable in all 19 patients by gentle contrast injection into drainage tubes. Three patients had concurrent biliary fistulas. In 18 of 19 patients, fluid samples yielded positive bacterial cultures. Successful percutaneous evacuation of fluid was achieved in 17 of 19 patients (89%). The mean duration of drainage was 31 days. Conclusion: Percutaneous drainage of abscess following pancreaticoduodenectomy is effective in virtually all patients despite the coexistence of enteric and biliary fistulas

  8. The effect of volatility on percutaneous absorption.

    Topically applied chemicals may volatilize, or evaporate, from skin leaving behind a chemical residue with new percutaneous absorptive capabilities. Understanding volatilization of topical medications, such as sunscreens, fragrances, insect repellants, cosmetics and other commonly applied topicals may have implications for their safety and efficacy. A systematic review of English language articles from 1979 to 2014 was performed using key search terms. Articles were evaluated to assess the relationship between volatility and percutaneous absorption. A total of 12 articles were selected and reviewed. Key findings were that absorption is enhanced when coupled with a volatile substance, occlusion prevents evaporation and increases absorption, high ventilation increases volatilization and reduces absorption, and pH of skin has an affect on a chemical's volatility. The articles also brought to light that different methods may have an affect on volatility: different body regions; in vivo vs. in vitro; human vs. Data suggest that volatility is crucial for determining safety and efficacy of cutaneous exposures and therapies. Few articles have been documented reporting evaporation in the context of percutaneous absorption, and of those published, great variability exists in methods. Further investigation of volatility is needed to properly evaluate its role in percutaneous absorption.

    To discuss the causes of treatment failure in percutaneous spine injections for low back pain or radiculopathy by analyzing patients who have experienced negative treatment effect on their first visit and a positive treatment effect on their second visit. The authors reviewed the cases of 24 patients who visited the pain intervention outpatient department in our hospital due to back pain or radiculopathy. All patients reviewed experienced a negative treatment effect following their first spine injection, but a positive treatment effect following the second injection. The dates of the cases range from June 2003 to May 2004. Two radiologists analyzed the possible causes of the negative treatment effect following the first injection therapies by considering clinical aspects as well as reviewing radiological images. The most common condition was the presence of the change in the level of the second selective nerve root block (n=13). In seven cases, the methods for administering the injections were changed to facet block (n=2), midline epidural block (n=1), selective nerve root block (n=3) and caudal epidural block (n=1). In four cases, there were no changes in the methods for administering the injections nor were there any changes in the level of the selective nerve root block between first and second visit. In those cases, after reviewing spot radiographs performed during injection, we attributed the causes of failure of injection therapy to an inappropriate distribution of drugs. We can improve the effect of percutaneous spine injections for low back pain or radioculopathy by determining the exact level of perineural root block, trying alternative methods, and insuring a good distribution of the injected drugs

    Purpose: To report on the nephron-sparing, percutaneous ablation of a large renal cell carcinoma by combined superselective embolization and percutaneous radiofrequency ablation. Materials and Methods: A 5 cm renal cell carcinoma of a 43-year-old drug abusing male with serologically proven HIV, hepatitis B and C infection, who refused surgery, was superselectively embolized using microspheres (size: 500 - 700 μm) and a platinum coil under local anesthesia. Percutaneous radiofrequency ablation using a 7F LeVeen probe (size of expanded probe tip: 40 mm) and a 200 Watt generator was performed one day after transcatheter embolization under general anesthesia. Results: The combined treatment resulted in complete destruction of the tumor without relevant damage of the surrounding healthy renal tissue. The patient was discharged 24 hours after RF ablation. No complications like urinary leaks or fistulas were observed and follow up CT one day and 4 weeks after the radiofrequency intervention revealed no signs of residual tumor growth. Conclusion: The combined transcatheter embolization and percutaneous radiofrequency ablation of renal cell carcinoma has proved technically feasible, effective, and safe in this patient. It may be offered as an alternative treatment to partial or radical nephrectomy under certain circumstances. Abbreviations: RF = radiofrequency ablation; CT = computed tomography; HIV = human immunodeficiency virus. (orig.) [de

    Percutaneous biliary dilation was done in 3 patients with benign strictures. The first case was 50-year-old male who had multiple intrahepatic stones with biliary stricture. The second 46-year-old female and the third 25-year-old male suffered from recurrent cholangitis with benign stricture of anastomotic site after choledocho-jejunostomy. In the first case, a 6mm diameter Grunzing dilatation balloon catheter was introduced through the T-tube tract. In the second case, the stricture was dilated with two balloons of 5mm and 8mm in each diameter sequentially through the U-loop tract formed by surgically made jejunostomy and percutaneous transhepatic puncture. In the third case, the dilatation catheter was introduced through the percutaneous transhepatic tract. Dilatation was made with a pressure of 5 to 10 atmospheres for 1 to 3 minutes duration for 3 times. In all 3 cases, the strictures were successfully dilated and in second and third cases internal stent was left across the lesion for prevention of restenosis.

    Core tissue for histologic study is believed by many pathologist to be more diagnostic than material from needle aspiration. Recently introduced automatched biopsy gun simplifies core biopsies with increased quantity and quality of samples. Authors performed 38 percutaneous biopsies from 38 patients with 18G automated biopsy guns under US guide. Diagnostic target tissues were obtained in 33 biopsies(87%), inadequate tissues in 4(11%), and adequate but not of target tissue in 1(3%). There was no major complication requiring treatment, but pain needing analgesics and pain with nausea/vomiting were experienced in 2 and 1 biopsies respectively. Average number of needle passes was 1.5. We concluded that US guided gun biopsy was a easy and safe way to obtain tissue samples of good quantity and quality, especially useful in hospitals without constant availability of specialist in cytopathology

    Full Text Available ObjectiveTo investigate the safety and feasibility of percutaneous intraductal radiofrequency ablation (palliative therapy in the treatment of malignant obstructive jaundice. MethodsThis study included 20 patients with unresectable malignant obstructive jaundice, who were treated in the First Affiliated Hospital of Zhengzhou University from January 2013 to March 2014. Nine of them (test group underwent percutaneous intraductal radiofrequency ablation plus metallic biliary stent placement. The other 11 similar cases (control group underwent metallic biliary stent placement alone after successful percutaneous transhepatic cholangiography. Operative complications and remission of jaundice were observed, and the stent patency after at 3 and 6 months after operation was evaluated and compared between the two groups. ResultsAll patients were followed completely by outpatient or telephone. The stent patency rate at 3 months after operation was 9/9 in the test group and 8/11 in the control group (χ2=2.888, P=0.218, and the stent patency rates at 6 months were 7/8 and 3/11, respectively (χ2=6.739, P=0.02. During follow-up, one case in the test group died of gastrointestinal bleeding at 113 d after operation; one case in the control group died of liver failure at 57 d after operation and one case died of disseminated intravascular coagulation at 142 d. ConclusionPercutaneous intraductal radiofrequency ablation is safe and feasible in the treatment of malignant biliary obstruction, and the preliminary efficacy in prolonging the patency of self-expanding metallic stent is satisfactory. However, this therapy needs to be further verified via large-sample randomized controlled studies.

    Aim: To evaluate the outcome of percutaneous cholecystostomy in critically ill patients with acute cholecystitis. Materials and methods: The study group included critically ill patients who underwent percutaneous cholecystostomy for acute cholecystitis at a tertiary medical centre in 2007–2011. Data on complications, morbidities, surgical outcome, and imaging findings were collected from the medical files and radiology information system. Results: There were 48 women (59.3%) and 33 men (40.7%), with a median age of 82 years (range 47–99 years). Seventy-one (88%) had calculous cholecystitis and 10 (12%), acalculous cholecystitis. The drain was successfully inserted in all cases with no immediate major procedural complications. Fifteen patients (18.5%) died in-hospital within 30 days, mainly (93%) due to septic shock (14/15), another 20 patients (24.7%) died during the study period of unrelated co-morbidities. Of the remaining 46 patients, 36 (78.2%) had surgical cholecystectomies. In patients with acalculous cholecystitis, the drain was removed after cessation of symptoms. Transcystic cholangiography identified five patients with additional stones in the common bile duct. They were managed by pushing the stones into the duodenum via the cystostomy access, sparing them the need for surgical exploration. Conclusions: Early percutaneous gallbladder drainage is safe and effective in critically ill patients in the acute phase of cholecystitis, with a high technical success rate. Surgical results in survivors are better than reported in patients treated surgically without drainage. Bile duct stones can be eliminated without creating an additional access

    Percutaneous destruction of cancer cells using a radiofrequency energy source has become an accepted part of the modern armamentarium for managing malignancies. Radiofrequency ablation (RFA) is a relatively novel procedure for treating recurrent and metastatic tumors. It is used for debulking tumors and as adjuvant therapy for palliative care apart from its role as a pain management tool. Its use in the third world countries is limited by various factors such as cost and expertise. In the remotest parts of India, where economic development has been slow, abject poverty with poor health care facilities advanced malignancies present a challenge to health care providers. We undertook this study to assess the safety of the percutaneous RFA tumor ablation as a therapeutic or palliative measure in patients where surgery was not possible. We observed that RFA may be an effective, alternative therapeutic modality for some inoperable tumors where other therapeutic modalities cannot be considered. Palliative and therapeutic image-guided RFAs of tumors may be the only treatment option in patients who are inoperable for a variety of reasons. To assess the safety and complications of RFA in such a patient population is important before embarking upon any interventions given their physically, mentally, and socially compromised status in a country such as India. To assess the safety of percutaneous image-guided radiofrequency tumor ablation and to note the various immediate and early complications of the intervention. This was a prospective, observational study conducted in Tata Main Hospital, Jamshedpur, Jharkhand, India. After approval by the Hospital Approval Committee all patients who consented for percutaneous RFA of their tumor admitted in the hospital were included after taking fully informed consent from patient/close relative keeping the following criteria in view. Patients who were likely to derive a direct benefit in the survival or as a palliative measure for relief

    The objective of this retrospective study was to evaluate the outcome of patients with acute necrotizing pancreatitis treated by active percutaneous necrosectomy. By searching the radiological, surgical and internal medicine databases, all patients with acute necrotizing pancreatitis treated by active percutaneous necrosectomy between 1992 and 2004 were identified. Demographic, laboratory, and clinical data, and details about invasive procedures were collected by reviewing patient charts, radiological and surgical reports. The computed tomography severity index (CTSI) scores were determined by reviewing CT images. Eighteen patients were identified. Median Ranson score on admission was 2. The Acute Physiology and Chronic Health Evaluation (APACHE) II score was median 22. Median CTSI score was 7. Initially all patients were treated with CT-guided drainage placement. Because passive drainage proved not to be effective, subsequent minimally invasive, percutaneous necrosectomy was performed. Eight out of 18 patients recovered fully without the need for surgery. Ten of 18 patients required additional surgical necrosectomy. For one of ten patients, percutaneous necrosectomy allowed postponing surgery by 39 days. Four of ten surgically treated patients died: three from septic multiorgan failure, one from pulmonary embolism. Percutaneous minimally invasive necrosectomy can be regarded as a safe and effective complementary treatment modality in patients with necrotizing pancreatitis. It is suitable for a subset of patients to avoid or delay surgery. (orig.)

    Medical treatment using antibiotics and postural drainage has been widely adopted as a treatment method of pulmonary abscess, accompanied by surgical methods in cases intractable to drug therapy. However long-term therapy may be required, and the tolerance of organisms to antibiotics or other complications are apt to be encountered, during medical treatment. To shorten the convalescent period or to decrease the risk of invasive procedures, rather simple and relatively easy interventional techniques such as transbronchial or percutaneous catheter drainage have been successfully tried. We have performed 12 cases of percutaneous drainages of lung abscesses under fluoroscope guidance. This report is on the results of this procedure.

    We analyze our experience with the management of biliary strictures (BSs) in 27 pediatric patients who underwent liver transplantation with the diagnosis of BS. Mean recipient age was 38 months (range, 2.5-182 months). In all patients percutaneous transhepatic cholangiography, biliary catheter placement, and bilioplasty were performed. In 20 patients the stenoses were judged resolved by percutaneous balloon dilatation and the catheters removed. Mean number of balloon dilatations performed was 4.1 (range, 3-6). No major complications occurred. All 20 patients are symptom-free with respect to BS at a mean follow-up of 13 months (range, 2-46 months). In 15 of 20 patients (75%) one course of percutaneous stenting and bilioplasty was performed, with no evidence of recurrence of BS at a mean follow-up of 15 months (range, 2-46 months). In 4 of 20 patients (20%) two courses of percutaneous stenting and bilioplasty were performed; the mean time to recurrence was 9.8 months (range, 2.4-24 months). There was no evidence of recurrence of BS at a mean follow-up of 12 months (range, 2-16 months). In 1 of 20 patients (5%) three courses of percutaneous stenting and bilioplasty were performed; there was no evidence of recurrence of BS at a mean follow-up of 10 months. In conclusion, BS is a major problem following pediatric liver transplantation. Radiological percutaneous treatment is safe and effective, avoiding, in most cases, surgical revision of the anastomosis.

    The results of CT/US-guided percutaneous drainage in 35 patients with pancreatic pseudocysts are reported. 27 patients recovered without surgery and no further treatment was required. 8 patients required a subsequent surgery due to recurrence. The role of CT/US-guided percutaneous drainage in pancreatic pseudocysts as well as an analysis of the technical aspects associated with a successful procedure are discussed. Although US may be used, we believe CT is safer and allows more precise localisation and guidance in the treatment of pseudocysts. (orig.) [de

    The management of peptic ulcers has dramatically changed and the incidence of elective surgery for gastroduodenal peptic ulcers has markedly decreased; hence, the incidence of emergency surgery for perforated peptic ulcers has slightly increased. In select cases, conservative therapy can be used as an alternative for treating perforated gastroduodenal ulcers. In this study, we evaluated the efficacy of percutaneous abdominal drainage for the conservative treatment of perforated gastroduodenal ulcers. We retrospectively studied 51 patients who had undergone conservative therapy for perforated gastroduodenal ulcers. These patients were divided into 2 groups on the basis of the initial treatment with conservative therapy with or without percutaneous drainage: group PD included patients who had undergone percutaneous drainage and group NPD, patients who had undergone non-percutaneous drainage. In the PD group, 14.3% (n=3) of the patients did not respond to conservative therapy, while this value was 43.3% (n=13) in the NPD group. The 2 groups differed significantly with respect to conversion from conservative therapy to surgery (pperforated gastroduodenal ulcers should be performed only in the case of patients meeting the required criteria; its combination with percutaneous intraperitoneal drainage is effective as initial conservative therapy.

    Although several multicenter registries have evaluated percutaneous coronary intervention (PCI) procedures in Korea, those databases have been limited by non-standardized data collection and lack of uniform reporting methods. We aimed to collect and report data from a standardized database to analyze PCI procedures throughout the country. Both clinical and procedural data, as well as clinical outcomes data during hospital stay, were collected based on case report forms that used a standard set of 54 data elements. This report is based on 2014 Korean PCI registry cohort data. A total of 92 hospitals offered data on 44967 PCI procedures. The median age was 66.0 interquartile range 57.0-74.0 years, and 70.3% were men. Thirty-eight percent of patients presented with acute myocardial infarction and one-third of all PCI procedures were performed in an urgent or emergency setting. Non-invasive stress tests were performed in 13.9% of cases, while coronary computed tomography angiography was used in 13.7% of cases prior to PCI. Radial artery access was used in 56.1% of all PCI procedures. Devices that used PCI included drug-eluting stent, plain old balloon angioplasty, drug-eluting balloon, and bare-metal stent (around 91%, 19%, 6%, and 1% of all procedures, respectively). The incidences of in-hospital death, non-fatal myocardial infarction, and stroke were 2.3%, 1.6%, and 0.2%, respectively. These data may provide an overview of the current PCI practices and in-hospital outcomes in Korea and could be used as a foundation for developing treatment guidelines and nationwide clinical research.

    To analyze the clinical results and complications of fluoroscopy guided internal-external pull-type percutaneous radiological gastrostomy (pull-type-PRG) and conventional external-internal percutaneous radiological gastrostomy (push-type-PRG). A total of 253 patients underwent radiological gastrostomy between January 2002 and January 2010. Data were collected retrospectively from radiology reports, Chart review of clinical notes, procedure reports, discharge summaries and subsequent hospital visits. Statistical analysis was performed to compare the two methods for gastrostomy with respect to peri-interventional aspects and clinical results. 128 patients received the Pull-type-PRG whereas the other 125 patients were served with the Push-type-PRG. Indications for gastrostomy were similar in these two groups. The most frequent indications for the both methods were stenotic oesophageal tumors or head/neck tumors (54.7% in pull-type-PRG, 68% in push-type-PRG). Gastrostomy procedures were successful in 98.3% in pull-type-PRG compared to 92% in push-type-PRG. There was no procedure-related mortality. Compared to Push-type-PRG, the peri-interventional complication rate was significantly reduced in pull-type-PRG (14.8% versus 34.4%, P = 0.002). Compared to the external-internal push-type-PRG, the internal-external Pull-type-PRG showed a high primary success rate and a decreased incidence of peri-interventional complications. (orig.)

    2015-01-01

    Full Text Available The presented article focuses on the important matters of development of intraoperative and postoperative complications in patients with urolithiasis undergoing percutaneous operative treatment for coral calculus of a solitary or sole functioning kidney. Complications of percutaneous X-ray-endoscopic operations in these patients always require careful medical and diagnostic approach, as they can lead to oppression of an already impaired solitary kidney function and, as a consequence, can have life-threatening nature. They are divided into two groups: intraoperative and postoperative complications. Intraoperative complications include: bleeding, damage of the renal pelvis in the course of creating of puncture access, perforation of internal organs, loss of stroke. Postoperative complications include: development of acute inflammation in a single kidney, bleeding, urinoma or hematoma development, progression of renal failure, leave of residual concretions, organ loss. There is a sufficient amount of data on the development of complications after percutaneous endoscopic surgeries in the literature, but very few works are devoted to a solitary kidney matter. The object of this study was the group of patients with urolithiasis, coral nephrolithiasis by a solitary or a single functioning kidney, who were on treatment in the urology department of the N.I.

    Full text: Percutaneous transhepatic cholangiography (PTC) is an X-ray or US guided procedure that involves the injection of a contrast material directly into the bile ducts inside the liver to produce pictures of them. If a blockage or narrowing is found, additional procedures may be performed: 1. insertion of a catheter to drain excess bile out of the body or both - internal and external; 2. plastic endoprothesis placement; 3. self-expandable metal stents placement to help open bile ducts or to bypass an obstruction and allow fluids to drain. Current percutaneous biliary interventions include percutaneous transhepatic cholangiography (PTC) and biliary drainage to manage benign and malignant obstructions. Internal biliary stents are either plastic or metallic, and various types of each kind are available. Internal biliary stents have several advantages. An external tube can be uncomfortable and have a psychological disadvantage. An internal stent prevents the problems related to external catheters, for example, pericatheter leakage of bile and the need for daily flushing. The disadvantages include having to perform endoscopic retrograde cholangiopancreatography (ERCP) or new PTC procedures to obtain access in case of stent obstruction. Better patency rates are reported with metallic than with plastic stents in cases of malignant obstruction, though no effect on survival is noted. Plastic internal stents are the cheapest but reportedly prone to migration. Metallic stents are generally not used in the treatment of benign disease because studies have shown poor long-term patency rates. Limited applications may include the treatment of patients who are poor surgical candidates or of those in whom surgical treatment fails. Most postoperative strictures are treated surgically, though endoscopic and (less commonly) percutaneous placement of nonmetallic stents has increasingly been used in the past few years. Now there are some reports about use of biodegradable biliary

    The purpose of this study was to evaluate the success of percutaneous transgastric cystgastrostomy as a single-step procedure. We performed a retrospective analysis of single-step percutaneous transgastric cystgastrostomy carried out in 12 patients (8 male, 4 female; mean age 44 years; range 21-70 years), between 2002 and 2007, with large symptomatic pancreatic pseudocysts for whom up to 1-year follow-up data (mean 10 months) were available. All pseudocysts were drained by single-step percutaneous cystgastrostomy with the placement of either one or two stents. The procedure was completed successfully in all 12 patients. The pseudocysts showed complete resolution on further imaging in 7 of 12 patients with either enteric passage of the stent or stent removal by endoscopy. In 2 of 12 patients, the pseudocysts showed complete resolution on imaging, with the stents still noted in situ. In 2 of 12 patients, the pseudocysts became infected after 1 month and required surgical intervention. In 1 of 12 patients, the pseudocyst showed partial resolution on imaging, but subsequently reaccumulated and later required external drainage. In our experience, percutaneous cystgastrostomy as a single-step procedure has a high success rate and good short-term outcomes over 1-year follow-up and should be considered in the treatment of large symptomatic cysts.

    Over the past 4 years, 55 cases (one transudate, 28 exudates, and 26 empymas) were drained. Surgical chest tubes alone were used in 35 drainages, percutaneous catheters alone in five drainages, and both types in 15 drainages. Percutaneous catheter drainage was successful in 12 of 20 drainages (60%). Surgical tube drainage was successful in 18 of 50 drainages (36%). The success rate for the nonempyema group was 45% with both types of drainage. For the empyema group, the success rate for percutaneous catheter drainage was 66% vs 23% for surgical tube drainage. Seven major complications occurred with surgical tube drainage, but only one major complication occurred with percutaneous catheter drainage. Radiologically guided percutaneous catheter drainage should be the procedure of choice for pleural fluid drainage. It has a higher success rate for empyemas and is associated with less complications

    28 primary liver abscesses, including 9 amoebic abscesses, in 24 patients were drained percutaneously. Indication for drainage in amoebic abscesses was imminent rupture and clinical symptoms as pleural effusion, lung atelectasis and pain. 95% of the primary abscesses were cured by percutaneous drainage and systemic antibiotic treatment. There was one recurrence of abscess, which was managed surgically. Reasons for drainage failure were: tumour necrosis and tumour perforation with secondary liver abscess. (orig.) [de

    Objectives To evaluate the short-term and long-term prognostic impacts of acute phase coronary collaterals to occluded infarct-related arteries (IRA) after ST-elevation myocardial infarction (STEMI) in the percutaneous coronary intervention (PCI) era. Design A prospective observational study. Setting Osaka Acute Coronary Insufficiency Study (OACIS) in Japan. Participants 3340 patients with STEMI from the OACIS database who were admitted to hospitals within 24 hours from the onset and who had a completely occluded IRA. Interventions Patients were divided into 4 groups according to the Rentrop collateral score (RCS) by angiography on admission (RCS-0, no visible collaterals; RCS-1, collaterals without IRA filling; RCS-2, collaterals with partial IRA filling; and RCS-3, collaterals with complete IRA filling). Primary outcome measures In-hospital and 5-year mortality. Results Patients with RCS-0/3 were older than patients with RCS-1/2, and the prevalence of previous myocardial infarction was highest in patients with RCS-3. Median peak creatinine phosphokinase levels decreased as RCS increases (p<0.001), suggesting the acute cardioprotective effects of collaterals. Although RCS-1 and RCS-2 collaterals were associated with better in-hospital mortality (adjusted OR 0.48, p=0.046 and 0.38, p=0.010 for RCS-1 and RCS-2, respectively) and 5-year mortality (adjusted HR 0.53, p=0.004 and 0.46, p<0.001 for RCS-1 and RCS-2, respectively) as compared with R-0, presence of RCS-3 collaterals was not associated with improved in-hospital (adjusted OR 1.35, p=0.331) and 5-year mortality (adjusted HR 0.98, p=0.920), possibly because worse clinical profiles in patients with RCS-3 may mask mortality benefit of coronary collaterals. Conclusions Presence of acute phase coronary collaterals such as RCS-1 and RCS-2 were associated with better in-hospital and 5-year mortality after STEMI in the contemporary PCI era. PMID:27412101

    Full text: Introduction: The risk of bile duct injury after laparoscopic cholecystectomy is higher than open cholecystectomy. Objective: To discuss the importance of minimally invasive treatment options in the management of bile duct injuries after laparoscopic cholecystectomy and to present our approach in the management. Materials and methods: Management of 25 patients with symptomatic bile duct injury after laparoscopic cholecystectomy was retrospectively evaluated. Percutaneous collection drainage, endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC) and percutaneous biliary drainage were performed for the management of the patients. Results: Mean age of the patients (15 women, 10 men) was 55. Either ultrasonography or computed tomography guided percutaneous drainage was performed in 13 patients. 9 of them completely recovered only with percutaneous drainage. In 4 of them ERCP was performed because of high drainage volume. In 9 of the patients with jaundice and high bilirubin levels ERCP was performed as the first option. And 3 patients were reoperated because of acute abdomen signs. ERCP, MRCP and PTC revealed type A in 7, type E2 in 3, type E3 in 3 and type E4 in 1 of the patients according to Strasberg classification. Conclusion: Presenting symptoms of the patients with symptomatic bile duct injury are useful in the determination of the treatment option.

    Full Text Available Introduction. Hallux rigidus is observed in approximately 2.5% of the adult population. Until now neither a unified classification of hallux rigidus appears to exist nor any clear principles to choose the surgical method. The variety of clinical and radiological signs explains the difficulties in establishing a comprehensive classification system and in selection of the criteria for surgical procedure. There are few published reports about hallux rigidus percutaneous surgical treatment. Existing papers are dedicated to a limited number of percutaneous techniques.The purpose of this study was to evaluate the efficacy of percutaneous techniques for surgical treatment of the first metatarsophalangeal joint osteoarthritis; to specify factors determining the choice of procedure; to develop a grading system of the hallux rigidus severity which will help in selection of surgery. Materials and methods. Based on 156 surgeries (107 patients the author demonstrated the possibilities of percutaneous techniques in the surgical treatment of hallux rigidus of different stages as well as provided a brief description of used surgical techniques.Results. The mean age of patients was 48.8 years (ranged from 18 to 73. The mean follow-up was 7 months (ranged from 3 to 54. At the specified time the treatment outcomes of 103 patients (150 feet were analyzed. Mean hospital stay was 0.78 days (ranged from 0 to 1. No infectious or wound-healing problems were observed. Overall, the patients were completely satisfied with the outcomes of 89 surgical treatment, qualified satisfaction was reported with patients in respect of outcomes of 57 surgeries. Four unsatisfactory outcomes were observed. The role of the relatively long first metatarsal in the development of hallux rigidus was confirmed. Conclusion. Percutaneous techniques provide successful treatment for all stages of hallux rigidus. The choice of a specific surgical technique may be challenging and requires

    The rendezvous technique typically involves combined efforts of interventional radiology, endoscopy, and surgery. It can be done solely percutaneously, whereby the interventionalist gains desired access to one point in the body by approaching it from two different access sites. We present the case of a woman who underwent cholecystectomy complicated by a bile duct injury. A percutaneous rendezvous procedure enabled placement of an internal-external drain from the intrahepatic ducts through the biloma and distal common bile duct and into the duodenum. Thus, a percutaneous rendezvous technique is feasible for managing a bile duct injury when endoscopic retrograde cholangio-pancreatography or percutaneous transhepatic cholangiogram alone has been unsuccessful.

    To present a novel miniature endoscopic system designed to improve the safety and efficacy of percutaneous nephrolithotomy, named the 'super-mini percutaneous nephrolithotomy' (SMP). The endoscopic system consists of a 7-F nephroscope with enhanced irrigation and a modified 10-14 F access sheath with a suction-evacuation function. This system was tested in patients with renal stones of operative duration was 45.6 min. The initial stone-free rate (SFR) was 90.1%. The SFR at the 3-month follow-up was 95.8%. Three patients required auxiliary procedures for residual stones. Complications occurred in 12.8% of the patients, all of which were Clavien grade ≤II and no transfusions were needed. In all, 72.3% of the patients did not require any kind of catheter, while 19.8% had JJ stents and 5.7% had nephrostomy tubes placed. The mean hospital stay was 2.1 days. SMP is a safe and effective treatment for renal stones of <2.5 cm. SMP may be particularly suitable for patients with lower pole stones and stones that ae not amenable to retrograde intrarenal surgery. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

    Cannulation of the great vessels is required for extracorporeal membrane oxygenation (ECMO). Currently, there is no guideline for optimal imaging modalities during percutaneous cannulation of ECMO. The purpose of this study was to describe percutaneous cannulation guided by point-of-care ultrasound (POCUS) for ECMO and compare it with fluoroscopy and landmark guidance. Three groups (POCUS-, fluoroscopy-, and landmark-guided) of percutaneous cannulation for ECMO were analyzed retrospectively in a tertiary academic hospital. In the POCUS-guided group, visual confirmation of guidewire and cannula by ultrasound in both the access and return cannula were essential for successful cannulation. Fluoroscopy- and landmark-guided groups were cannulated with the conventional technique. A total of 128 patients were treated by ECMO during the study period, of which 94 (73.4%) cases were venoarterial ECMO. This included 56 cases of extracorporeal cardiopulmonary resuscitation. Also, there were 30 (23.4%) cases of venovenous ECMO and 4 (3.1%) cases of venoarteriovenous ECMO. A total of 71 (55.5%) patients were cannulated under POCUS guidance, and 43 (33.6%) patients were cannulated under fluoroscopy guidance and 14 (10.9%) patients were cannulated by landmark guidance. No surgical cut downs were required. Misplacement of cannula occurred in 3 (2.3%) cases. All three occurred in the landmark-guided group. POCUS-guided cannulation is comparable to fluoroscopy-guided cannulation in terms of avoiding cannula misplacement. In our experience, POCUS-guided cannulation is a useful strategy over fluoroscopy- and landmark-guided cannulation during peripheral ECMO. Copyright © 2017 Elsevier Inc. All rights reserved.

    The successful dilatation of postsurgical concentric stenosis of an internal carotid artery using percutaneous transluminal angioplasty (PTA) is reported here. Only one such case has been previously documented. Review of the literature disclosed 16 patients who received transluminal angioplasty for stenosis of carotid arteries by percutaneous or open arteriotomy techniques. The authors feel that PTA may be the treatment of choice for postoperative concentric stenosis of a short segment of the carotid artery as opposed to surgical repair. (orig.)

    Pelvic fractures may lead to severe retroperitoneal bleeding. Percutaneous catheter embolisation has become an increasingly important therapeutic alternative to surgical intervention. Most studies dealing with this problem have been small and we have attempted to evaluate the method on the basis of our own experience and a review of the literature. The success rate of percutaneous embolisation appears to be about 94%. The use of blood transfusion dropped from an average of 25.7 units before embolisation to an average of 6.5 units after embolisation. In spite of this, mortality in these patients remains high at 43.3% because of the serious additional injuries. The advantages and disadvantages of various embolising materials are discussed and various techniques of percutaneous embolisation are described. (orig.) [de

    Full Text Available Background: Diabetes mellitus and admission blood glucose are important risk factors for mortality in ST segment elevation myocardial infarction patients, but their relative and individual role remains on debate. Objective: To analyze the influence of diabetes mellitus and admission blood glucose on the mortality of ST segment elevation myocardial infarction patients submitted to primary coronary percutaneous intervention. Methods: Prospective cohort study including every ST segment elevation myocardial infarction patient submitted to primary coronary percutaneous intervention in a tertiary cardiology center from December 2010 to May 2012. We collected clinical, angiographic and laboratory data during hospital stay, and performed a clinical follow-up 30 days after the ST segment elevation myocardial infarction. We adjusted the multivariate analysis of the studied risk factors using the variables from the GRACE score. Results: Among the 740 patients included, reported diabetes mellitus prevalence was 18%. On the univariate analysis, both diabetes mellitus and admission blood glucose were predictors of death in 30 days. However, after adjusting for potential confounders in the multivariate analysis, the diabetes mellitus relative risk was no longer significant (relative risk: 2.41, 95% confidence interval: 0.76 - 7.59; p-value: 0.13, whereas admission blood glucose remained and independent predictor of death in 30 days (relative risk: 1.05, 95% confidence interval: 1.02 - 1.09; p-value ≤ 0.01. Conclusion: In ST segment elevation myocardial infarction patients submitted to primary coronary percutaneous intervention, the admission blood glucose was a more accurate and robust independent predictor of death than the previous diagnosis of diabetes. This reinforces the important role of inflammation on the outcomes of this group of patients.

    Background: There has been debate over the indications for percutaneous endoscopic gastrostomy (PEG) in recent years in Japan. In addition, the level of satisfaction of patients and patient’s family after PEG remains unclear. The aim of this study was to investigate the current status of PEG and the level of satisfaction of patients and patients’ families after PEG in Japan. Methods: We reviewed the existing data of all patients who underwent PEG tube insertion at Yuri Kumiai General Hospital (Akita, Japan) between February 2000 and December 2010. We examined the following points: underlying diseases requiring PEG, levels of consciousness, and performance status. We also sent a questionnaire to the patients and patient’s families to ask about their satisfaction with and thoughts about PEG. Results: The data of 545 patients who underwent PEG were reviewed. There were 295 men and 250 women, with a mean age of 77.2 ± 11.4 years. PEG was indicated most frequently for cerebrovascular disorders (48.2%, 239/545). There were 515 (94.4%, 515/545) patients showing consciousness disturbance and 444 (81.5%, 444/545) bedridden patients. The questionnaire was answered by one patient himself and 316 patients’ families. When asked, “Was performing PEG a good decision?”, 57.5% (182/316) of the patients’ families answered yes. Meanwhile, when patients’ family members were asked if they would wish to undergo PEG if they were in the same condition as the patient, 28.4% (90/316) answered yes, whereas 55.3% (175/316) answered no. Conclusions: Few patients were able to make their own decision about PEG tube placement because of consciousness disturbance. As a result, many family members of the patients did not want to experience PEG for themselves. Future studies should be performed to clarify the quality of life and ethical aspects associated with PEG. PMID:27313796

    Six patients with solitary pyogenic splenic abscesses treated by CT-guided percutaneous drainage (by catheter or needle), are presented. There were 3 unilocular, purely intrasplenic abscesses and 3 complex lesions with loculations and perisplenic involvement. Percutaneous drainage and intravenous antibiotics were curative in 4 patients. In the other 2, who had multiloculated abscesses, despite initially successful drainage, splenectomy was performed because of intractable left upper quadrant pain in one case and persistent fever and drainage of pus after 30 days in the other. These patients also developed large, sterile left pleural effusions. Solitary pyogenic splenic abscesses - particularly if uniloculated - can be effectively treated by CT-guided percutaneous drainage. (orig.)

    Full Text Available Nephrolithiasis accelerates the renal failure in the patients with ADPKD. In order to evaluate the role of percutaneous nephrolithotomy in management of calculus in these patients, 11 patients with autosomal dominant polycystic kidney disease and renal stones were included in the study. Two patients had bilateral renal stones. All patients were treated by percutaneous nephrolithotomy under ultrasound guidance. 13 percutaneous nephrolithotomy procedures were performed in 1 stage by the urology team under ultrasound guidance. 5 people received second operation with flexible nephroscopy in lateral position. The success rate and morbidity and mortality of the technique and hospital stay were recorded. Results. The puncture procedure was fully successful in all cases. The renal function improved in these patients. 5 patients had moderate fever after the surgery. 5 patients received flexible nephroscopy to take out the residual calculi. 2 persons had ESWL therapy after the surgery. Conclusion. PCNL is an ideal, safe, and effective method to remove the stones from those patients with no definite increase in the risk of complication. The outcome and stone-free rate are satisfactory comparable to the PCNL in the patients without ADPKD.

    Objective: To evaluate the clinical value and limitations of percutaneous interventional forceps retrieval technique under fluoroscopic guidance in removing radiopaque foreign bodies in soft-tissue. Methods: A total of 4 105 consecutive soft-tissue injury patients with radiopaque foreign bodies, encountered in authors' hospital during the period from June 2005 to June 2010, were involved in this study. The diagnosis was confirmed by plain X-ray films in all patients. Additional CT scanning was performed in 1 591 patients, in some of them 3D reconstruction was adopted. With local anesthesia percutaneous interventional forceps retrieval of radiopaque foreign bodies (PIRFB) was carried out under C-arm video-fluoroscopic guidance. Results: Of all patients in this study, 61.34% (2 518/4 105) was treated by PIRFB (study group), and 38.66% (1 587/4 105) was not treated with PIRFB (control group). In study group,the complete and partial curative rate was 95.07% (2 394/2 518) and 4.81% (121/2 518) respectively, and the failure rate was 0.12% (3/2 518). Of 1 587 patients in control group, 25.02% (n=397) left hospital by patient's own reasons and 74.98% (n=1190) was discharged from hospital due to medical or technical reasons. In control group,the foreign objects were close to big vessels in 65.22% (1 035/1 587), large local hematoma was accompanied in 2.90% (46/1 587), associated traumatic pseudoaneurysm was seen in 1.32% (21/1 587) and the foreign objects were glass pieces and the like were found in 5.55% (88/1 587). No serious postoperative complications that required specific therapy, such as bleeding, infection and nerve damage, etc. occurred. CT, especially enhanced CT three-dimensional images, could precisely display the vasculatures nearby the foreign body, which helped make the correct judgment of the removal ability and the operation risk for foreign bodies with interventional procedure. Conclusion: Percutaneous interventional forceps retrieval technique under

Cryoablation was performed in a single session for this 9-cm mass with 24 h hospitalisation. At 2- and 6-month follow-up, the pain had completely disappeared, and magnetic resonance imaging demonstrated a significant decrease in size. Percutaneous cryoablation shows promise as a feasible and apparently safe method for local control in patients with symptomatic venous vascular malformations.

    To evaluate percutaneous short-term catheter drainage in the management of benign ovarian cysts in patients at increased surgical risk. Thirty-eight patients with simple ovarian cysts were treated with drainage of fluid content by catheters until output stopped. All patients were poor candidates for surgery. All procedures were performed under ultrasonographic (US) control and local anesthesia. Cytologic examination was performed in all cases. The patients were followed up monthly with color Doppler US for 12 months. Outcome measure was the recurrence of a cyst. During the 12-month follow-up period, 10 of 38 cysts recurred. Seven of the 10 cysts required further intervention, and three were followed up without intervention. Four of the seven patients who required further intervention underwent repeat transabdominal aspiration and three declined repeat aspiration and subsequently underwent surgery. After repeated aspirations, two of four cysts disappeared, one necessitated follow-up only, and one necessitated surgical intervention. Cyst volume (P = .009) and diameter (P = .001) were significantly larger in the cysts that recurred. No evidence of malignancy was reported in the cytologic examination in any patient. No patients developed malignancy during follow-up. No major complications were observed. The hospital stay was 1 day for all patients. The median duration of drainage in the groups with resolved and recurrent cysts was 1 day (interquartile range, 1-1) and 2 days (interquartile range, 1-3), respectively (P = .04). In patients considered poor candidates for open surgery or laparoscopy, percutaneous treatment of ovarian cysts with short-term catheter drainage without sclerotherapy appears to be a safe and effective alternative, with low recurrence rates.

    Full Text Available OBJECTIVE - To report the results of percutaneous occlusion of persistent ductus arteriosus with the Amplatzer prosthesis in 2 Brazilian cardiological centers. METHODS - From May 1998 to July 2000, 33 patients with clinical and laboratory diagnosis of persistent ductus arteriosus underwent attempts at percutaneous implantation of the Amplatzer prosthesis. The median age was 36 months (from 6 months to 38 years, and the median weight was 14kg (from 6 to 92kg. Sixteen patients (48.5% were under 2 years of age at the time of the procedure. All patients were followed up with periodical clinical and echocardiographic evaluations to assess the presence and degree of residual shunt and possible complications, such as pseudocoarctation of the aorta and left pulmonary artery stenosis. RESULTS - The minimum diameter of the arterial ducts ranged from 2.5 to 7.0mm (mean of 4.0±1.0, median of 3.9. The rate of success for implantation of the prosthesis was 100%. Femoral pulse was lost in 1 patient. The echocardiogram revealed total closure prior to hospital discharge in 30 patients, and in the follow-up visit 3 months later in the 3 remaining patients. The mean follow-up duration was 6.4±3.4 months. All patients were clinically well, asymptomatic, and did not need medication. No patient had narrowing of the left pulmonary artery or of the aorta. No early or late embolic events occurred, nor did infectious endarteritis. A new hospital admission was not required for any patient. CONCLUSION - The Amplatzer prosthesis for persistent ductus arteriosus is safe and highly effective for occlusion of ductus arteriosus of varied diameters, including large ones in small symptomatic infants.

    Percutaneous nephrolithotomy (PCNL) for staghorn calculi is one of the more challenging endourologic procedures. Although excellent stone-free rates are universally reported in the literature, complication rates vary widely, especially related to the need for blood transfusion. The purpose of this study was to evaluate the outcomes of PCNL for patients with staghorn calculi in a large series of patients at a single, tertiary referral, endourologic stone center. Between July 1990 and December 2005, 1338 patients underwent PCNL for renal stone disease at our institution. Among this group, 509 procedures were performed for patients with a partial or complete staghorn calculus. Data analysis included procedure time, length of hospital stay, number of access tracts, transfusion rates, other early and late complications, and stone-free status. Mean patient age was 53.8 years (range 4-84 yrs). The average procedure time was 104 minutes. Sixteen percent of the cases needed multiple access tracts (range 2-5), with the lower calix being the most commonly used in 64.1%, followed by the upper calix in 18.5% and the middle calix in 17.4%. Various intracorporeal lithotriptors were used, including ultrasound, pneumatic, electrohydraulic, and holmium:yttrium-aluminium-garnet laser. The transfusion rate among this group was 0.8%. There was no statistically significant difference in transfusion rates (0.7%-1.2% P = 0.24) or other major complications in patients who were treated with either a single tract or among those needing multiple tracts. Stone-free rates at hospital discharge and at 3 months follow-up were 78% and 91%, respectively. PCNL is a safe and effective procedure in the management of staghorn calculi, with outcomes similar to those reported for percutaneous management of smaller volume nonstaghorn stones. Attention to accurate tract selection and placement as well as possession of the full array of endourologic equipment are essential to achieving an excellent outcome.

    To determine the efficacy and safety of bedside percutaneous drainage procedures with ultrasound guidance in critically ill patients in the intensive care unit (ICU). Sixty five percutaneous drainage procedures performed at the bedside, in 39 ICU patients, were evaluated. All of the procedures were performed with ultrasound guidance alone. The procedures consisted of percutaneous drainage of abdominal (n=35) and pleural (n=27) fluids, percutaneous cholecystostomy (n=2) and percutaneous nephrostomy (n=1). The clinical responses were classified as 'complete response', 'partial response', 'failure' or 'undetermined'. The medical records were reviewed retrospectively to evaluate the clinical response. Technical success was achieved in 64 of the 65 procedures (98.5%). The complication rate was 13.8% (9 cases). There was no immediate procedure-related death or worsening of the clinical condition of the patients. The clinical responses after drainage were 'complete response' in 39 cases (60.9%). 'partial response' in 14 (21.9%), 'failure' in 3 (4.7%), and 'undetermined' in 8 (12.5%). Bedside drainage procedures with ultrasound guidance are effective and safe to perform when patients are too critically ill to be moved from the ICU to the angiography room

    Full Text Available Introduction. Spinopelvic dissociation injuries are historically treated with open reduction with or without decompressive laminectomy. Recent technological advances have allowed for percutaneous fixation with indirect reduction. Herein, we evaluate outcomes and complications between patients treated with open reduction versus percutaneous spinopelvic fixation. Methods. Retrospective review of patients undergoing spinopelvic fixation from a single, level one trauma center from 2012 to 2017. Patient information regarding demographics, associated injuries, and treatment outcome measures was recorded and analyzed. All fractures were classified via the AO Spine classification system. Results. Thirty-one spinopelvic dissociations were identified: 15 treated with open and 16 with percutaneous techniques. The two treatment groups had similar preoperative characteristics including spinopelvic parameters (pelvic incidence and lumbar lordosis. Compared to open reduction internal fixation, percutaneous fixation of spinopelvic dissociation resulted in statistically significantly lower blood loss (171 cc versus 538 cc; p=0.0013. There were no significant differences in surgical site infections (p=0.48 or operating room time (p=0.66. Conclusion. Percutaneous fixation of spinopelvic dissociation is associated with significantly less blood loss. Treatment outcomes in terms of infection, length of stay, operative cost, and final alignment between the open and percutaneous group were similar.

    Full Text Available Adrenalectomy is the definite treatment for aldosterone-producing adenoma (APA. Percutaneous ethanol or acetic acid injection with computed tomography (CT guidance has been described as a safe, noninvasive, and effective alternative treatment modality in patients with high surgical risk. We report on a man who was 49 years of age and presented with treatment-resistant hypertension and was later diagnosed with APA. CT-guided percutaneous ethanol injection (PEI was performed for this high surgical risk patient. He had aldosteronism recurrence 4 years after the ethanol injection, so a second PEI was performed. The tumor size was reduced and his blood pressure was normalized. Therefore, we suggest that clinicians should closely check aldosterone to renin ration and potassium level if percutaneous chemical ablation is considered in functioning adrenal adenomas.

    Randomized trials have demonstrated that primary angioplasty is more effective than intravenous thrombolysis in reducing mortality and morbidity in patients with acute myocardial infarction (AMI). The aim of this study was to assess the in-hospital mortality of patients with AMI admitted to the only tertiary care center in Kosovo, where coronary percutaneous intervention procedures are unavailable. We also assessed the impact of age and gender on in-hospital mortality. Patients and Consecutive patients with the diagnosis of AMI, admitted in our institution between 1999 and 2007, were included in this retrospective study. Of 2848 patients (mean age 61±11.3 years, 73.4% males) admitted with AMI, 292 (10.25%) patients died during in-hospital stay. The overall in-hospital mortality was 12.3% for women and 9.5% for men (P<.05). Women were significantly older than men (64.2±11 years vs 59.7±11.8 years, P<.05). Mean length of stay was 12.0±94 for women and 10.7±7.6 for men. From 1999 to 2007 there was an increase in the age of patients with AMI but the mortality rate remained stable.Compared to developed countries, patients with AMI in Kosovo present at an earlier age but have a higher mortality rate. Women with AMI had a significantly higher in-hospital mortality rate than men. The lack of percutaneous coronary intervention procedures in AMI patients may have contributed to the high in-hospital mortality in our population (Author).

    We describe the case of a 52-year woman with a 17-year history of obstructed defecation in whom all other standard treatments had failed and the patient had refused a colostomy. Her symptoms were controlled by percutaneous endoscopic colostomy with antegrade colonic irrigation. A percutaneous endoscopic colostomy tube was placed in the sigmoid colon endoscopically using a colonoscope and the patient irrigated two liters of water through the percutaneous endoscopic colostomy twice each day and was able to successfully evacuate her rectum without excess straining or discomfort. Percutaneous endoscopic colostomy is an alternative option to colostomy in the management of obstructed defecation.

    Observational studies favor percutaneous closure of patent foramen ovale (PFO) over medical treatment to reduce recurrent stroke while randomized trials fail to demonstrate significant superiority of percutaneous PFO closure. Few long-term studies are available post PFO closure. This study reports long-term clinical outcomes after percutaneous PFO closure. Between 1997 and 2006, 86 consecutive eligible patients with cerebrovascular events, presumably related to PFO, underwent percutaneous PFO closure. All 86 patients were invited to a long-term follow-up, which was carried out during 2011 and 2012. Percutaneous PFO closure was successfully performed in 85 of 86 patients. The follow-up rate was 100%. No cardiovascular or cerebrovascular deaths occurred. Two patients (both women) died from lung cancer during follow-up. Follow-up visits were conducted for 64 patients and the remaining 20 patients were followed up by phone. The mean follow-up time was 7.3 years (5 to 12.4 years). Mean age at PFO closure was 49 years. One patient had a minor stroke one month after PFO closure and a transient ischemic attack (TIA) two years afterwards. One other patient suffered from a TIA six years after closure. No long-term device-related complications were observed. Percutaneous PFO closure was associated with very low risk of recurrent stroke and is suitable in most patients. We observed no mortality and no long-term device-related complications related to PFO closure, indicating that percutaneous PFO closure is a safe and efficient treatment even in the long term.

    Preliminary study to assess the feasibility and safety of percutaneous nephrolithotomy (PCNL) as an ambulatory procedure. Between February 2011 and September 2012, 84 patients with renal calculi fulfilling the inclusion criteria were admitted to the Urology Department of Benha University Hospitals for PCNL. All patients were subjected to a full medical history, clinical, laboratory and radiological examinations. Tubeless PCNLs were done in the supine position, and an antegrade double-J stent was inserted. Operative time and intraoperative complications were recorded. Postoperatively, the hematocrit value, postoperative pain and analgesics, need of blood transfusion, stone-free rate, and length of hospital stay were recorded. Stable patients that could be safely discharged within 24 hours after surgery were considered ambulatory. All cases of tubeless PCNL were successfully done and no cases converted to open surgery. The overall stone-free rate was 91.7%, the mean postoperative pain score measured by the visual analog scale was 4.4 ± 1.2, the mean overall hematocrit deficit was 4.8 ± 2.2% and the mean hospital stay was 33.4 ± 17.5 hours. Ambulatory PCNL was accomplished in 60 out of 84 patients (71.4%) and double-J stents were removed 7-10 days postoperatively. In the non-ambulatory cases, double-J stents were removed after auxillary procedures were done according to each case. PCNL can be safely done on an ambulatory basis under strict criteria, but further studies are needed to confirm and expand these findings.

    2013-07-01

    Full Text Available INTRODUCTION: Supracondylar fracture of the humerus is a common injury in children. It accounts for 60% of fractures around the elbow children. If the fracture is not treated properly it may give rise to many complications like malunion, Volkmann’s ischemic contracture, nerve injury, arterial injury, skin slough, heterotopic bone formation , and stiffness of elbow. The management of displaced supracondylar fracture of the elbow is one of the most difficult of the many fractures seen in children. The purpose of the study was to evaluate the anatomical and functional results of treatment of supracondylar fractures of humerus with closed reduction and percutaneous ‘K’ wire fixation as a day care procedure and record associated complications, thus decreasing the cost of treating these fractures and hospitalization. METHODS: Fifty displaced closed extension type supracondylar fractures (Gartland’s type III of the humerus in children were treated by closed reduction and percutaneous fixation with Kirschner wires. All the patients selected for this study had been treated in a day care unit and were discharged in the same evening and followed up at 3 and 6 weeks and 3 months. Open fractures, fractures with neurovascular complications and children older than 15 yrs were excluded. The final results were evaluated by Flynn’s criteria. RESULTS: The majority (72%, of the patients had fracture displaced posteomedially, Fourty one of the fifty patients had satisfactory results. The majority of the patients were male, and the average age was 8-9 years. CONCLUSION: Percutaneous fixation of supracondylar humerus done as a day care procedure is an acceptable modality of treatment and reduces the duration of hospital stay for the patient.

    From March 1987 to July 1989, six patients (five adults and one child) with lung abscess (size, 5-13 cm in diameter) were treated with percutaneous aspiration and drainage. In each case, the puncture was made where the wall of the abscess was in contact with the pleural surface. An 8 to 10 Fr cartheter was inserted for drainage. Five of 6 had a dynamatic clinical response within 24 hours of the drainage. Percutaneous drainage was successful with complete abscess resolution in four and partial resolution in one patient. No response was seen in the rest one. The duration of drainage ranged from 7 to 18 days(average, 15.5 days) in successful cases. One case of the failure in drainage was due tio persistent aspiration of the neurologically impaired patient. In one patient, the abscess resolved after drainage but recurred after inadvertent removal of the catheter 7 days after insertion. In two patients, concurrent pleural empyema was resolved completely by the drainage. Computed tomography provide anatomic details necessary for choosing the puncture site and avoiding a puncture of the lung parenchyma. Percutaneous catheter drainage is safe and effective method for treating patient with lung abscess.

    CT-guided percutaneous core needle biopsy has been shown in adults to be an effective diagnostic tool for a large number of musculoskeletal malignancies. To characterize our experience with CT-guided percutaneous core needle biopsy of pediatric bone lesions and determine its utility in diagnosing pediatric osseous lesions, in a population where such lesions are commonly benign. From 2000 to 2009, 61 children underwent 63 CT-guided percutaneous biopsies. Radiological, pathological and clinical records were reviewed. Fourteen biopsies (22%) were performed on malignant lesions, while 49 biopsies (78%) were performed on benign lesions. Forty-nine of the 63 biopsies (78%) were adequate; these children underwent no further tissue sampling. Fourteen of the 63 biopsies (22%) were inadequate or non-conclusive. Of these patients, 12 underwent open biopsy. Retrospective analysis of percutaneous biopsies in these patients demonstrates that 9/12 provided clinically relevant information, and 4/12 patients received final diagnoses that confirmed initial core biopsy findings. No malignancies were diagnosed as benign on percutaneous biopsy. Overall, percutaneous core needle biopsy provided accurate diagnostic information in 84% (53/63) of biopsies. Our results demonstrate that CT-guided percutaneous biopsy is safe and beneficial in children. This study supports the use of CT-guided percutaneous core needle biopsy for primary diagnosis of pediatric bone lesions. (orig.)

    We wanted to present the results of percutaneous management of ureteral injuries that were diagnosed late after cesarean sections (CS). Twenty-two cases with 24 ureteral injuries that were diagnosed late after CS underwent percutaneous nephrostomy (PN), antegrade double J (DJ) catheter placement and balloon dilatation or a combination of these. The time for making the diagnosis was 21 +- 50.1 days. The injury site was the distal ureter in all cases (the left ureter: 13, the right ureter: 7 and bilateral: 2). Fifteen complete ureteral obstructions were detected in 13 cases. Ureteral leakage due to partial (n = 4) or complete (n = 3) rupture was noted in seven cases. Two cases had ureterovaginal fistula. All the cases were initially confirmed with antegrade pyelography and afterwards they underwent percutaneous nephrostomy. Balloon dilatation was needed in three cases. Antegrade DJ stents were placed in 10 cases, including the three cases with balloon dilatation. Repetititon of percutaneous nephrostomy with balloon dilatation and DJ stent placement was needed in one case with complete obstruction. All the cases were followed-up with US in their first week and then monthly thereafter for up to two years. Eighteen ureters (75%) were managed by percutaneous procedures alone. A total of six ureter injuries had to undergo surgery (25%). Percutaneous management is a good alternative for the treatment of post-CS ureteral injuries that are diagnosed late after CS. Percutaneous management is at least preparatory for a quarter of the cases where surgery is unavoidable

    BACKGROUND: Current guidelines recommend that comatose out-of-hospital cardiac arrest patients with ST-segment elevations (STEs) following return of spontaneous circulation (ROSC) should be referred for an acute coronary angiography. We sought to investigate the diagnostic value of the pre......-hospital ROSC-ECG in predicting ST-elevation myocardial infarction (STEMI). METHOD: ROSC-ECGs of 145 comatose survivors of out-of-hospital cardiac arrest, randomly assigned in the Target Temperature Management trial, were classified according to the current STEMI ECG criteria (third universal definition...... interval (CI) 62-84), specificity of 65% (95% CI 53-75) and a positive and negative predictive value of 65% (95% CI 54-76) and 73% (95% CI 61-83) in predicting STEMI. Time to ROSC was significantly longer (24 minutes vs. 19 minutes, P=0.02) in STE compared with no STE patients. Percutaneous coronary...

    To study the results and complications of percutaneous needle tenotomy for superficial retracted tendons in patients with brain damage. Prospective observational study. University hospital. Patients with severe brain damage (N=38; mean age, 60.7y; age range, 24-93y; 21 women) requiring surgical management of contractures and eligible for percutaneous needle tenotomy were enrolled between February 2015 and February 2016. The percutaneous needle tenotomy gesture was performed by a physical medicine and rehabilitation physician trained by an orthopedic surgeon, under local or locoregional anesthesia. Treated tendons varied among patients. All patients were evaluated at 1, 3, and 6 months to assess surgical outcomes (joint range of motion [ROM], pain, and functional improvement) while screening for complications. Improvements in ROM (37/38) and contractures-related pain (12/12) were satisfactory. Functional results were satisfactory (Goal Attainment Scale score ≥0) for most patients (37/38): nursing (n=12), putting shoes on (n=8), getting in bed or sitting on a chair (n=6), verticalization (n=7), transfers and gait (n=8), and grip (n=2). Five patients had complications related to the surgical gesture: cast-related complications (n=2), hand hematoma (n=2), and cutaneous necrosis of the Achilles tendon in a patient with previous obliterative arteriopathy of the lower limbs (n=1). Percutaneous needle tenotomy yields good results in the management of selected superficial muscle and tendon contractures. The complications rate is very low, and this treatment can be an alternative to conventional surgery in frail patients with neurologic diseases.

    This study compared the stone opacity effect in patients who had radiopaque and radiolucent stones in percutaneous nephrolithotomy (PCNL) results. The medical records of 171 complete supine PCNL procedures were gathered. Patients were categorized into two groups: those with radiopaque (n=141) and those with radiolucent (n=30) stones. Kidney, ureter and bladder x-ray was done a day after PCNL and Ultrasound imaging was done two weeks later to evaluate the stone free rate. A stone free result was defined as having less than 4 mm residual stone size. Outcome parameters were compared by univariate analysis and those which were significantly different between the two groups were assessed by multivariate binary logistic regression analysis. There were no significant differences in age, sex, body mass index, hypertension, diabetes mellitus, pre-surgery hemoglobin, pre-surgery serum creatinine, stone and also surgery-related parameters between the two groups. Stone free rate, surgery time, complication-related parameters, hemoglobin drop, serum creatinine and glomerular filtration rate (GFR) changes were similar in both groups based on univariate analysis. The radiopaque group had higher post-surgery GFR (p=0.04) and longer hospital stay (p=0.009). However, opacity had no effect on these outcomes after multivariate analysis. Higher post-surgery GFR was seen in patient with higher GFR before surgery (p<0.0001). Also, higher hemoglobin before surgery was correlated with less hospital stay (p=0.001). The complete supine percutaneous nephrolithotomy outcomes are similar in patients with radiopaque and radiolucent stones.

    Background: Percutaneous aspiration of abscesses under ultrasonography (USG) and computer tomography (CT) scan has been well described. With recurrence rate reported as high as 66%. The open drainage and percutaneous continuous drainage (PCD) has reduced the recurrence rate. The disadvantage of PCD under CT is radiation hazard and problems of asepsis. Hence a technique of clinically guided percutaneous continuous drainage of the psoas abscess without real-time imaging overcomes these problems...

    PURPOSE: Percutaneous drainage of subphrenic abscesses is technically more difficult because lung and pleura may be transgressed during catheter insertion. The purpose of this paper is to determine the incidence of thoracic complications secondary to subphrenic abscess drainage and to determine factors that may alter this. The authors' series consists of 100 subphrenic abscesses that were drained percutaneously. Patients range in age from 14 to 75 years. Abscesses were secondary to surgery (splenectomy, pancreatectomy, partial hepatectomy, gastrectomy), pancreatitis, and trauma. Catheters ranged in size from 8 to 14 F and were inserted via trocar or Seldinger technique. Thoracic complications of pneumothorax or empyema were determined from follow-up chest radiographs or CT scans

    The aim of this study was to examine the relationship between the total length of the stents and the postoperative life quality of patients with multi-vessel coronary artery disease who undergo percutaneous coronary intervention (PCI). Using the short-form health survey (SF-36) items, we analyzed the data on the postoperative life quality of 166 patients with multi-vessel coronary artery disease who underwent percutaneous transluminal coronary intervention in the Department of Cardiology of the First Affiliated Hospital of Henan University of Science and Technology from September 2011 to September 2013. Follow-up was performed 6 months later. All of the dimensionalities, except general health and mental health, showed significantly higher scores after PCI. No significant relationships were observed between the total length of the stents and the postoperative life quality of patients with multi-vessel coronary artery disease who underwent PCI. PCI can effectively improve the postoperative life quality of patients; however, there was no significant relationship between the total length of the stents and postoperative life quality of patients.

    The clinical course of elderly patients with acute myocardial infarction (AMI) can sometimes unexpectedly result in an adverse outcome even when therapy appears to be successful. We suspect that specific factors may characterize this worsening of status during hospitalization. This study examines whether the pre-hospital physical activity status of the elderly treated with percutaneous coronary intervention (PCI) for AMI affects their in-hospital course. We studied 110 consecutive patients, aged 80 or older, who had undergone emergent PCI for AMI. Patients were divided into two groups based on clinical presentation: Better Killip class (Killip classes I and II) and Worse Killip class (Killip classes III and IV). Patients were also divided into two groups based on pre-hospital physical activity status, determined retrospectively by review of medical records: Good physical activity (n=57) comprising those able to go out alone independently and Poor physical activity comprising those mainly confined to home (n=53). The overall in-hospital mortality rate was 9.1% for the study population. The Worse Killip class group had a higher in-hospital mortality rate than the Better Killip class group (27.8% vs 5.4%, respectively; p=0.0102). In addition, the Poor physical activity group had a higher in-hospital mortality rate than the Good physical activity group (15.1% vs. 3.5%, respectively; p=0.047). These data suggest that pre-hospital physical activity status in elderly patients with AMI may affect in-hospital mortality as well as Killip class.

    Full Text Available Objective To discuss the clinical effects of minimally invasive percutaneous pedicle screw fixation in the treatment of single segment thoracolumbar fracture without neurological symptoms.  Methods From June 2012 to October 2014, 38 neurologically intact patients with thoracolumbar fracture underwent surgeries, including open pedicle screw fixation in 16 cases and percutaneous pedicle screw fixation in 22 cases. The incision length, operation time, intraoperative blood loss, postoperative drainage and postoperative complication were recorded and compared between 2 groups. Thoracolumbar orthophoric, lateral and flexion-extension X-ray was used to measure sagittal Cobb angle and height of injured anterior vertebral body before and after operation. Modified Macnab evaluation was used to assess the curative effects 3 months after operation. Results The success rate of operations in 38 patients was 100%. There were a total of 114 vertebral bodies fused and 228 pedicle screws implanted. Patients in the percutaneous pedicle screw group had smaller incision length [(10.55 ± 1.23 cm vs (18.50 ± 2.50 cm, P = 0.000], less intraoperative blood loss [(32.55 ± 7.22 ml vs (320.50 ± 15.48 ml, P = 0.000], shorter hospital stay [(6.55 ± 1.50 d vs (13.50 ± 2.52 d, P = 0.000], and without postoperative drainage. The follow-up after operation ranged from 3 to 6 months, with the average time of (4.65 ± 1.24 months. Cobb angle was reduced (P = 0.000 and height of injured anterior vertebral body were improved signifcantly (P = 0.000 3 months after surgery in both groups. The total effective rate was 14/16 in open surgery group, and 86.36% (19/22 in percutaneous pedicle screw group, however, the difference between 2 groups was not significant (P = 1.000. Conclusions Minimally invasive percutaneous pedicle screw fixation is a surgical method with less iatrogenic injury, less intraoperative blood loss and quick recovery for patients with thoracolumbar fracture

    Aim: Percutaneous needle liver biopsy (PLB) is frequently associated with pain and anxiety. This may discourage the patients for biopsy, and rebiopsies, if needed. We planned a study to investigate the efficacy of additional analgesia or sedation for PLB. Materials and methods: The study has been designed as a single-center, prospective study. The PLB was planned for 18- to 65-year-old consecutive patients who were included in the study. The patients were divided into three premedication groups as control, Meperidine, and Midazolam. Hospital Anxiety and Depression Scale (HADS) was used to measure each subject’s anxiety level. Fifteen minutes before the biopsy, 1 mL 0.9% NaCl subcutaneously (sc), 1 mg/kg (max 100 mg) Meperidine sc, or 0.1 mg/kg (max 5 mg) Midazolam intravenously was administered to patients respectively. Then PLB was done with 16 G Menghini needle. The day after, the patients were asked about feelings regarding biopsy. Results: Groups were similar by gender and age. The HADS scores prior to PLB and on visual analog scale (VAS, 1-10 points) score during PLB were similar. In the three groups, 7, 12, and 7 patients, respectively, experienced no pain. Other patients explained pain as mild or moderate or severe. The number of patients who agreed for possible rebiopsy was higher in Meperidine and Midazolam groups than in the control group. Conclusion: Premedication with Meperidine or Midazolam in PLB would improve patients’ tolerance, comfort, and attitude against a possible repeat PLB.

  4. A cross-sectional analysis of variation in charges and prices across California for percutaneous coronary intervention.

    Directory of Open Access Journals (Sweden)

    Renee Y Hsia

    Full Text Available Though past studies have shown wide variation in aggregate hospital price indices and specific procedures, few have documented or explained such variation for distinct and common episodes of care.We sought to examine the variability in charges for percutaneous coronary intervention (PCI with a drug-eluting stent and without major complications (MS-DRG-247, and determine whether hospital and market characteristics influenced these charges.We conducted a cross-sectional analysis of adults admitted to California hospitals in 2011 for MS-DRG-247 using patient discharge data from the California Office of Statewide Health Planning and Development. We used a two-part linear regression model to first estimate hospital-specific charges adjusted for patient characteristics, and then examine whether the between-hospital variation in those estimated charges was explained by hospital and market characteristics.Adjusted charges for the average California patient admitted for uncomplicated PCI ranged from $22,047 to $165,386 (median: $88,350 depending on which hospital the patient visited. Hospitals in areas with the highest cost of living, those in rural areas, and those with more Medicare patients had higher charges, while government-owned hospitals charged less. Overall, our model explained 43% of the variation in adjusted charges. Estimated discounted prices paid by private insurers ranged from $3,421 to $80,903 (median: $28,571.Charges and estimated discounted prices vary widely between hospitals for the average California patient undergoing PCI without major complications, a common and relatively homogeneous episode of care. Though observable hospital characteristics account for some of this variation, the majority remains unexplained.

  5. Percutaneous tracheostomy: a comprehensive review

    Rashid, Ashraf O.

    2017-01-01

    Tracheostomy is a common procedure. It can be done surgically or percutaneously by dilating the stoma using Seldinger technique. Percutaneous tracheostomy (PT) is now routinely performed by surgeons and non-surgeons such as intensivists and anesthesiologists in the intensive care units (ICU) all over the world. Although obesity, emergent tracheostomy, coagulopathy, inability to extend the neck and high ventilator demand (HVD) were initially thought to be a relative contraindication, recent data suggest safety of PT in these patient population. Ultrasound can be helpful in limited cases to identify the neck structure especially in patients with a difficult anatomy. Bronchoscopy during PT can shorten the duration and avoid complications. PT has favorable complication rate, lower infection rate, shorter procedural duration and is cost-effective. Experience with the technique and careful planning is needed to minimize any avoidable potential complication. PMID:29214070

    2002-01-01

    Percutaneous cholecystostomy (PC), a technique that consists of percutaneous catheter placement in the gallbladder lumen under imaging guidance, has become an alternative to surgical cholecystostomy in recent years. Indications of PC include calculous or acalculous cholecystitis, cholangitis, biliary obstruction and opacification of biliary ducts. It also provides a potential route for stone dissolution therapy and stone extraction. Under aseptic conditions and ultrasound guidance, using local anesthesia, the procedure is carried out by using either modified Seldinger technique or trocar technique. Transhepatic or transperitoneal puncture can be performed as an access route. Several days after the procedure transcatheter cholangiography is performed to assess the patency of cystic duct, presence of gallstones and catheter position. The tract is considered mature in the absence of leakage to the peritoneal cavity, subhepatic, subcapsular, or subdiaphragmatic spaces. Response rates to PC in the literature are between the range of 56-100% as the variation of different patient population. Complications associated with PC usually occur immediately or within days and include haemorrhage, vagal reactions, sepsis, bile peritonitis, pneumothorax, perforation of the intestinal loop, secondary infection or colonisation of the gallbladder and catheter dislodgment. Late complications have been reported as catheter dislodgment and recurrent cholecystitis. PC under ultrasonographic guidance is a cost-effective, easy to perform and reliable procedure with low complication and high success rates for critically ill patients with acute cholecystitis. It is generally followed by elective cholecystectomy, if possible. However, it may be definitive treatment, especially in acalculous cholecystitis

    Full Text Available There are several options for the treatment of varicocele, including surgical repair either by open or microsurgical approach, laparoscopy, or through percutaneous embolization of the internal spermatic vein. The ultimate goal of varicocele treatment relies on the occlusion of the dilated veins that drain the testis. Percutaneous embolization offers a rapid recovery and can be successfully accomplished in approximately 90% of attempts. However, the technique demands interventional radiologic expertise and has potential serious complications, including vascular perforation, coil migration, and thrombosis of pampiniform plexus. This review discusses the common indications, relative contraindications, technical details, and risks associated with percutaneous embolization of varicocele.

    Objective: To analyze the complications and treatment technique of percutaneous nephrostomy. Methods: 247 hydronephrosis eases treated with percutaneous nephrostomy guided by ultrosound and fluroseopy flora Januray 2007 to April 2008 were evaluated retrospectively and the causes of complications and suitable treatments were analyzed. Results: The successful rate of percutaneous nephrostomy in 247 hydronephrotic cases reached 100%. In all cases, 4 cases occurred with severe complications (1.6%) including 3 massive hemorrhage and 1 septic shock during the operation. The minor complications (25 cases, 10% ) were hematuria, urinary tract infection, local haematoma, perirenal haematoma, detachment of drainage tube with obstruction and exodus, internal double-J catheter displacement and obstruction, etc. Conclusion: The operative safety and treatment efficacy of percutaneous nephrostomy could be achieved through skillful management and comprehensive preoperative evaluation of the risk factors for the complications.

    To describe patient characteristics, hospital investigations and interventions and early mortality among patients being hospitalized after out-of-hospital cardiac arrest in two hospitals. Municipality of Göteborg, Sweden. All patients suffering an out-of-hospital cardiac arrest who were successfully resuscitated and admitted to hospital between 1 October 1980 and 31 December 1996. All patients were resuscitated by the same Emergency Medical Service and admitted alive to one of the two city hospitals in Göteborg. Of 579 patients admitted to Sahlgrenska Hospital, 253 (44%) were discharged alive and of 459 patients admitted to Ostra Hospital, 152 (33%) were discharged alive (P percentage of patients admitted to Sahlgrenska Hospital underwent coronary angiography (P < 0.001), electrophysiological testing (P < 0.001), Holter recording (P < 0.001), echocardiography (P = 0.004), percutaneous transluminal coronary angioplasty (PTCA, P = 0.009), implantation of automatic implantable cardioverter defibrillator (AICD, P = 0.03) and exercise stress tests (P = 0.003). Inhabitants in the catchment area of Ostra Hospital had a less favourable socio-economic profile. Survival after out-of-hospital cardiac arrest may be affected by the course of hospital management. Other variables that might influence survival are socio-economic factors and cardiorespiratory status on admission to hospital. Further investigation is called for as more patients are being hospitalised alive after out-of-hospital cardiac arrest.

  12. Comparison of early and late percutaneous tracheotomies in adult intensive care unit

    2014-11-01

    Full Text Available Background and objectives: Percutaneous tracheotomy has become a good alternative for patients thought to have prolonged intubation in intensive care units. The most important benefits of tracheotomy are early discharge of the patient from the intensive care unit and shortening of the time spent in the hospital. Prolonged endotracheal intubation has complications such as laryngeal damage, vocal cord paralysis, glottic and subglottic stenosis, infection and tracheal damage. The objective of our study was to evaluate potential advantages of early percutaneous tracheotomy over late percutaneous tracheotomy in intensive care unit. Methods: Percutaneous tracheotomies applied to 158 patients in adult intensive care unit have been analyzed retrospectively. Patients were divided into two groups as early and late tracheotomy according to their endotracheal intubation time before percutaneous tracheotomy. Tracheotomies at the 0–7th days of endotracheal intubation were grouped as early and after the 7th day of endotracheal intubation as late tracheotomies. Patients having infection at the site of tracheotomy, patients with difficult or potential difficult intubation, those under 18 years old, patients with positive end-expiratory pressure above 10 cmH2O and those with bleeding diathesis or platelet count under 50,000 dL−1 were not included in the study. Durations of mechanical ventilation and intensive care stay were noted. Results: There was no statistical difference among the demographic data of the patients. Mechanical ventilation time and time spent in intensive care unit in the group with early tracheotomy was shorter and the difference was statistically significant (p < 0.05. Conclusion: Early tracheotomy shortens mechanical ventilation duration and intensive care unit stay. For that reason we suggest early tracheotomy in patients thought to have prolonged intubation.

    We wanted to present the results of percutaneous management of ureteral injuries that were diagnosed late after cesarean sections (CS). Twenty-two cases with 24 ureteral injuries that were diagnosed late after CS underwent percutaneous nephrostomy (PN), antegrade double J (DJ) catheter placement and balloon dilatation or a combination of these. The time for making the diagnosis was 21 ± 50.1 days. The injury site was the distal ureter in all cases (the left ureter: 13, the right ureter: 7 and bilateral: 2). Fifteen complete ureteral obstructions were detected in 13 cases. Ureteral leakage due to partial (n = 4) or complete (n = 3) rupture was noted in seven cases. Two cases had ureterovaginal fistula. All the cases were initially confirmed with antegrade pyelography and afterwards they underwent percutaneous nephrostomy. Balloon dilatation was needed in three cases. Antegrade DJ stents were placed in 10 cases, including the three cases with balloon dilatation. Repetititon of percutaneous nephrostomy with balloon dilatation and DJ stent placement was needed in one case with complete obstruction. All the cases were followed-up with US in their first week and then monthly thereafter for up to two years. Eighteen ureters (75%) were managed by percutaneous procedures alone. A total of six ureter injuries had to undergo surgery (25%). Percutaneous management is a good alternative for the treatment of post-CS ureteral injuries that are diagnosed late after CS. Percutaneous management is at least preparatory for a quarter of the cases where surgery is unavoidable

    Although randomized trials have clearly demonstrated the clinical efficacy with regimens of platelet glycoprotein IIb/IIIa antagonists that result in >80% inhibition of baseline platelet aggregation in percutaneous coronary intervention (PCI), there are no data available concerning the optimal duration of infusion of these agents. In an era when the length of hospitalization has a major impact on health care costs, the determination of the optimal duration of the infusion of these drugs after PCI is of great relevance. The investigators therefore sought to determine the optimal length of the infusion of eptifibatide after PCI by analyzing the outcomes of patients enrolled in the Enhanced Suppression of the Platelet IIb/IIIa Receptor With Integrilin Therapy trial who were randomized to treatment with eptifibatide.

    33 abdominal abscesses associated with fistulae in 31 patients were treated by percutaneous drainage. 19 of these patients had had surgery immediately preceding the drainage. In 64% the percutaneous drainage led to a diagnosis of an internal fistula. Additional therapeutic measures, because of the fistula, were necessary in 45% (operation, biliary drainage, repositioning of catheter). The average duration of drainage was 29 days. 77% of those abscesses which could be drained were treated successfully. Mortality in the entire series was 19%. (orig.) [de

    We sought to determine if advances in percutaneous coronary intervention (PCI) are associated with better outcomes among patients with diabetes mellitus (DM). Patients with DM enrolled in the National Heart, Lung, and Blood Institute (NHLBI) early PTCA Registry (1985-1986) were compared to those in the subsequent contemporary Dynamic Registry (1999-2002) for in-hospital and one-year cardiovascular outcomes. The study population included 945 adults with DM, 325 from the PTCA Registry and 620 from the Dynamic Registry. Multivariable Cox regression models were built to estimate the risk of clinical events. Dynamic Registry patients were older, had more noncardiac comorbidities, and a lower mean ejection fraction (50.5% vs 57.8%, P diabetes had more advanced coronary disease, in-hospital and late adverse events were lower. A combination of the use of stents and an increase in adjunctive medical therapy are likely responsible for the observed improvements in outcomes in contemporary PCI.

    Coagulation disorders and an immune-altered state are common among total artificial heart patients. In this context, we sought to evaluate the safety of percutaneous dilatational tracheostomy in cases of prolonged need for mechanical ventilatory support. We retrospectively analysed the charts of 11 total artificial heart patients who received percutaneous dilatational tracheostomy. We focused on early and late complications. We observed no major complications and no procedure-related deaths. Early minor complications included venous oozing (45.4%) and one case of local infection. Late complications, including subglottic stenosis, stomal infection or infections of the lower respiratory tract, were not observed. In conclusion, percutaneous dilatational tracheostomy in total artificial heart patients is safe.

    Nine peritoneovenous shunts were positioned by percutaneous technique in seven patients with advanced malignancy causing severe refractory ascites, and in two patients with hepatic cirrhosis (one with hepatocarcinoma). In all patients the shunts were percutaneously placed through the subclavian vein in the angiographic suite under digital fluoroscopic guide. No complications directly related to the procedure occurred. The shunt was successfully positioned in all patients in 60 min average time. No patient showed symptoms related to pulmonary overload or to disseminated intravascular coagulation. All patients had a significant improvement of the objective symptoms related to ascites such as respiratory symptoms, dyspepsia, and functional impairment to evacuation describing an improvement of their quality of life. Maximum shunt patency was 273 days. Percutaneous placement of peritoneovenous shunt is a safe, fast, and inexpensive procedure, extremely useful in resolution of refractory ascites, reducing symptoms, and allowing effective palliation, with a great improvement in quality of life.

    Aim: To evaluate the effect of antecedent antimicrobial therapy on diagnostic yield from percutaneous image-guided disc-space sampling. Materials and methods: A retrospective review of the electronic health records of all patients who underwent image-guided percutaneous sampling procedures for suspected discitis/osteomyelitis over a 5-year period was performed. One hundred and twenty-four patients were identified. Demographics, medical history, and culture results were recorded as well as duration of presenting symptoms and whether antecedent antibiotic therapy had been administered. Results: Of the 124 patients identified who underwent image-guided percutaneous disc-space sampling, 73 had received antecedent antibiotic treatment compared with 51 who had not. The overall positive culture rate for the present study population was 24% (n=30). The positive culture rate from patients previously on antibiotics was 21% (n=15) compared with 29% (n=15) for patients who had not received prior antibiotic treatment, which is not statistically significant (p=0.26). Eighty-six percent (n=63) of patients who had antecedent antibiotics received treatment for 4 or more days prior to their procedure, whereas 14% (n=10) received treatment for 1–3 days prior to their procedure. The difference in culture positivity rate between these two groups was not statistically significant (p=0.43). Culture results necessitated a change in antibiotic therapy in a third of the patients who had received antecedent antibiotic therapy. Conclusion: Antecedent antibiotic therapy, regardless of duration, did not result in significantly diminished diagnostic yield from percutaneous sampling for suspected discitis/osteomyelitis. The present results suggest that percutaneous biopsy may nonetheless yield positive diagnostic information despite prior antimicrobial therapy. If the diagnostic information may impact choice of therapeutic regimen, percutaneous biopsy should still be considered in cases where

    Percutaneous endoscopic colostomy (PEC) is a technique derived from percutaneous endoscopic gastrostomy. When conservative treatment of chronic obstipation fails, colon irrigation via PEC seems less invasive than surgical interventions. However, previous studies have noted high complication rates of PEC, mostly related to infections. Our aim was to report our experiences with PEC in patients with chronic refractory constipation. Retrospective analysis of all patients who underwent PEC for refractory constipation in our secondary referral hospital between 2009 and 2016. Twelve patients received a PEC for chronic, refractory constipation. Short-term efficacy for relief of constipation symptoms was good in 8 patients and moderate in 4 patients. Two patients had the PEC removed because of spontaneous improvement of constipation. Three patients, who initially noticed a positive effect, preferred an ileostomy over PEC after 1-5 years. One PEC was removed because of an abscess. Long-term efficacy is 50%: 6 patients still use their PEC after 3.3 years of follow-up. No mortality occurred. PEC offers a technically easily feasible and safe treatment option for patients with chronic constipation not responding to conventional therapy. Long-term efficacy of PEC in our patients is 50%. © 2017 John Wiley & Sons Ltd.

    A percutaneous catheter which can be looped by means of a nylon thread was used in 32 patients for percutaneous biliary drainage. The catheter can be fixed in this way and is thereby prevented from migrating from the biliary system. The catheter is not suitable for proximal obstructions. Problems may arise during the removal of the nylon thread and loss of looping of the point of catheter. (orig.) [de

    Percutaneous patent foramen ovale (PFO) closure is a therapeutic option to prevent recurrent cerebral ischaemia in patients with cryptogenic stroke and transient cerebral ischaemia (TIA). The apparent lack of benefit seen in previous randomised trials has, in part, reflected inclusion of patients with alternate mechanisms of stroke. The role of formal neurology involvement in accurately delineating the likely aetiology of stroke or TIA is crucial in appropriate identification of patients for device closure. Furthermore, as the benefits of device closure may accrue over time, long-term follow-up is essential to define the role of device closure in management of presumed cryptogenic stroke. We retrospectively reviewed our experience with percutaneous PFO device closure since 2005. All subjects who underwent PFO closure at John Hunter and Lake Macquarie Private Hospitals were included in the study. All patients referred for device closure following cryptogenic stroke or TIA had first undergone formal neurology review with appropriate imaging and exclusion of paroxysmal atrial arrhythmia. Patients with a history of transient ischaemic attack (TIA) are frequently referred to a specialised clinic, aimed to identify patients with conditions not referable to cerebral ischaemia, with investigations initiated by the specialist clinic to elucidate an underlying aetiology. Outcome data was derived from the Hunter New England Area Local Health District Cardiac and Stroke Outcomes Unit, in addition to review of the medical record. The Cardiac and Stroke Outcomes Unit prospectively identified all patients presenting with stroke, TIA and atrial fibrillation. One hundred and twelve consecutive patients undergoing percutaneous patent foramen ovale closure between 2005 and 2015 were identified. The average age was 42.7 years and 57 (50.9%) patients were male. Cryptogenic stroke (68.8%) and transient cerebral ischaemia (23.2%) were the most common indications for PFO closure, with the

    To investigate the associations of hospital competition and number of cardiologists per hospital (indicating the decentralization and centralization of healthcare resources, respectively) with 30-day in-hospital mortality, healthcare spending, and length of stay (LOS) among patients with acute myocardial infarction (AMI) in Japan. We collected data from 23,197 AMI patients admitted to 172 hospitals between 2008 and 2011. Hospital competition and number of cardiologists per hospital were analyzed as exposure variables in multilevel regression models for in-hospital mortality, healthcare spending, and LOS. Other covariates included patient, hospital, and regional variables; as well as the use of percutaneous coronary intervention (PCI). Hospitals in competitive regions and hospitals with a higher number of cardiologists were both associated lower in-hospital mortality. Additionally, hospitals in competition regions were also associated with longer LOS durations, whereas hospitals with more cardiologists had higher spending. The use of PCI was also associated with reduced mortality, increased spending and increased LOS. Centralization of cardiologists at the hospital level and decentralization of acute hospitals at the regional level may be contributing factors for improving the quality of care in Japan. Policymakers need to strike a balance between these two approaches to improve healthcare provision and quality. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Local ablation therapy is considered as a conventional treatment option for patients with early stage hepatocellular carcinoma (HCC. Although radiofrequency (RF ablation is widely used for HCC, the use of cryoablation has been increasing as newer and safer cryoablation systems have developed. The thermodynamic mechanism of freezing and thawing used in cryoablation is the Joule-Thomson effect. Cryoablation destroys tissue via direct tissue destruction and vascular-related injury. A few recent comparative studies have shown that percutaneous cryoablation for HCCs is comparable to percutaneous RF ablation in terms of long term therapeutic outcomes and complications. Cryoablation has several advantages over RF ablation such as well visualization of iceball, no causation of severe pain, and lack of severe damage to great vessels and gallbladder. It is important to know the advantages and disadvantages of cryoablation compared with RF ablation for improvement of therapeutic efficacy and safety.

    The percutaneous absorption of diclofenac diethylammonium 1.16% (w/w) in a combination of emulsion cream and gel (Voltaren Emulgel) and of diclofenac sodium 1% (w/w) in a cream formulation (Voltaren cream) was investigated in guinea-pig, rabbit and man. The percutaneous absorption of diclofenac sodium in guinea-pig was 3 to 6% of the dose when the cream formulation in doses of 320, 100 or 40 mg was applied on 10 cm2 of occluded skin and left in place for 6 h. The transdermal delivery of 14C-labelled diclofenac yielded plateau plasma concentrations of radiotracer from 1.5 h after application until removal of the residual cream. Subsequently the steady state drug depots in the skin and muscle tissue were depleted promptly. During daily administration the steady state levels in the muscle tissue in proximity to the application site were about 3 times higher than in distant muscle tissue. By topical application on knee joints of rabbits diclofenac penetrated into the patellar ligament, the adipose corpus and the synovial fluid. In man the percutaneous absorption was 6% of the dose when the Emulgel formulation was spread by 5 mg/cm2 and left for 12 h on non-occluded skin. The pattern of metabolites of diclofenac in human urine was the same after topical and oral administration. In man, upon daily topical administration of 3 times 2.5 g cream formulation (10 mg/cm2) the diclofenac steady state plasma levels were 20 to 40 nmol/l.(ABSTRACT TRUNCATED AT 250 WORDS)

    Thanks to minimally invasive procedures, frail and elderly patients can also benefit from innovative technologies. More than 14 million implanted pacemakers deliver impulses to the heart muscle to regulate the heart rate (treating bradycardias and blocks). The first human implantation of defibrillators was performed in early 2000. The defibrillator detects cardiac arrhythmias and corrects them by delivering electric shocks. The ongoing development of minimally invasive technologies has also broadened the scope of treatment for elderly patients with vascular stenosis and aneurysmal disease as well as other complex vascular pathologies. The nonsurgical cardiac valve replacement represents one of the most recent and exciting developments, demonstrating the feasibility of replacing a heart valve by way of placement through an intra-arterial or trans-ventricular sheath. Percutaneous devices are particularly well suited for the elderly as the surgical risks of minimally invasive surgery are considerably less as compared to open surgery, leading to a shorter hospital stay, a faster recovery, and improved quality of life.

    Percutaneous ablation for electrical disconnection of the arrhythmogenic foci using various forms of energy has become a well-established technique for treating atrial fibrillation (AF). Success rate in preventing recurrence of AF episodes is high although associated with a significant incidence of pulmonary vein (PV) stenosis and other rare complications. Clinical workup of AF patients includes imaging before and after ablative treatment using different noninvasive and invasive techniques such as conventional angiography, transoesophageal and intracardiac echocardiography, computed tomography (CT) and magnetic resonance imaging (MRI), which offer different information with variable diagnostic accuracy. Evaluation before percutaneous ablation involves assessment of PVs (PV pattern, branching pattern, orientation and ostial size) to facilitate position and size of catheters and reduce procedure time as well as examining the left atrium (presence of thrombi, dimensions and volumes). Imaging after the percutaneous ablation is important for assessment of overall success of the procedure and revealing potential complications. Therefore, imaging methods enable depiction of PVs and the anatomy of surrounding structures essential for preprocedural management and early detection of PV stenosis and other ablation-related procedures, as well as long-term follow-up of these patients.

Current standard antithrombotic therapy after coronary stent implantation consists of lifelong aspirin and clopidogrel for a variable period depending in part on the stent type. Despite its well-established efficacy in reducing cardiac-related death, myocardial infarction, and stroke, dual antiplatelet therapy with aspirin and clopidogrel is not without shortcomings. While clopidogrel may be of little beneficial effect if administered immediately prior to PCI and may even increase major bleeding risk if coronary artery bypass grafting is anticipated, early discontinuation of the drug may result in insufficient antiplatelet coverage with thrombotic complications. Optimal and rapid inhibition of platelet activity to suppress ischemic and thrombotic events while minimizing bleeding complications is an important therapeutic goal in the management of patients undergoing percutaneous coronary intervention. In this article we present an overview of the literature on clinical trials evaluating the different aspects of antithrombotic therapy in patients

    To compare the efficacy of sacroiliac joint anterior approach with double reconstruction plate and computer assisted navigation percutaneous sacroiliac screw for treating Tile C1 pelvic fractures. Fifty patients with pelvic Tile C1 fractures were randomly divided into two groups ( n =25 for each) in the orthopedic department of West China Hospital of Sichuan University from December 2012 to November 2014. Patients in group A were treated by sacroiliac joint dislocation with anterior plate fixation. Patients in group B were treated with computerized navigation for percutaneous sacroiliac screw. The operation duration,intraoperative blood loss,incision length,and postoperative complications (nausea,vomiting,pulmonary infection,wound complications,etc.) were compared between the two groups. The postoperative fracture healing time,postoperative patient satisfaction,and postoperative fractures MATTA scores (to evaluate fracture reduction),postoperative MAJEED function scores,and SF36 scores of the patients were also recorded and compared. No significant differences in baseline characteristics were found between the two groups of patients. All of the patients in both groups had their operations successfully completed. Patients in group B had significantly shorter operations and lower intraoperative blood loss,incision length and postoperative complications than those in group A ( P 0.05). Sacroiliac joint anterior approach with double reconstruction plate and computer assisted navigation percutaneous sacroiliac screws are both effective for treating Tile C1type pelvic fractures,with similar longterm efficacies. However,computer assisted navigation percutaneous sacroiliac screw has the advantages of less trauma,less bleeding,and quicker.

    The study compared the effect of earplug-delivered sleep-inducing music on sleep in persons with percutaneous transluminal coronary angiography in the cardiac care unit. Diverse types of music have been claimed to improve sleeping elsewhere, but relatively little is known in South Korea. Most studies investigating the effect of sleep-inducing music on sleep have involved persons with insomnia, even though many persons with cardiovascular disease in the intensive care unit suffer from sleeping problems. There is a need to investigate the effect of sleep-inducing music on sleep disorders in persons with percutaneous transluminal coronary angiography in the cardiac care unit. An experimental research design was used. Data collection was conducted in the cardiac care unit of K University Hospital in D city, from 3 September-4 October 2010. Fifty-eight subjects participated and were randomly assigned to the experimental group (earplug-delivered sleep-inducing music for 52 min beginning at 10:00 pm, while wearing an eyeshield, n = 29) and the control group (no music, but earplugs and eyeshield worn, n = 29). The quantity and quality of sleep were measured using questionnaires at 7 am the next morning for each group. Participants in the experimental group reported that the sleeping quantity and quality were significantly higher than control group (t = 3·181, p = 0·002, t = 5·269, p music significantly improved sleep in patients with percutaneous transluminal coronary angiography at a cardiac care unit. Offering earplugs and playing sleep-inducing music may be a meaningful and easily enacted nursing intervention to improve sleep for intensive care unit patients.

    Perforated appendicitis can result in potentially serious complications requiring prolonged medical care. The optimal approach to successfully managing this condition is controversial. Review of 80 consecutive cases of pediatric acute perforated appendicitis with intra-abdominal infection (IAI) medically managed with parenteral antibiotics and percutaneous drainage (PD) during a 7-year period. All patients received broad spectrum parenteral antibiotic therapy. One-third were hospitalized for >2 weeks. IAI was identified on admission in 60% compared with developing during hospitalization in 40% of cases. Before performing PD, the mean duration of antibiotic therapy in those who developed IAI during hospitalization was 6 days. IAI cultures yielded 127 bacterial isolates; polymicrobial infection occurred in 65% of cases. Only 7% of aspirates were sterile. The most common pathogens were Escherichia coli (82%), of which 5 isolates exhibited extended-spectrum β-lactamase production, and streptococci (40%). At the time of PD, 60% were febrile (mean duration of in-hospital fever, 7.5 days); 67% defervesced within 24 hours after the procedure. Posthospitalization abdominal complications (recurrent IAI or appendicitis) occurred in one-third of patients. Children with perforated appendicitis and IAI often have a complicated and prolonged clinical course. Medical management consisting solely of parenteral antibiotic therapy is frequently ineffective in resolving IAI. Rapid clinical improvement commonly follows PD.

    Contrast-induced nephropathy (CIN) is an important cause of acute renal failure. Identification of risk factors of CIN and creating a simple risk scoring for CIN after percutaneous coronary intervention (PCI) is important. A prospective single center study was conducted in Kuwait chest disease hospital. All patients admitted to chest disease hospital for PCI from March to May 2005 were included in the study. Total of 247 patients were randomly assigned for the development dataset and 100 for the validation set using the simple random method. The overall occurrence of CIN in the development set was 5.52%. Using multivariate analysis; basal Serum creatinine, shock, female gender, multivessel PCI, and diabetes mellitus were identified as risk factors. Scores assigned to different variables yielded basal creatinine > 115 micron mol/L with the highest score(7), followed by shock (3), female gender, multivessel PCI and diabetes mellitus had the same score (2). Patients were further risk stratified into low risk score ( 1 2). The developed CIN model demonstrated good discriminative power in the validation population. In conclusion, use of a simple risk score for CIN can predict the probability of CIN after PCI; this however needs further validation in larger multicenter trials. (author)

    Percutaneous transhepatic gallbladder drainage (PTGBD) is a procedure to resolve acute cholecystitis (AC). It may decrease the technical difficulty of laparoscopic cholecystectomy (LC) and thus may facilitate successful surgery when a patients' condition improves. However, the timing of LC after PTGBD remains controversial. From 2004 to 2010, cholecystectomy after PTGBD was performed in 67 patients with AC. Group I members underwent LC within 72 h of PTGBD (n = 21), whereas group II members underwent LC at more than 72 h after PTGBD (n = 46). The open conversion rate was similar in the two groups. The perioperative complication rate was higher in group I than in group II, but with marginal significance (19.0 vs. 4.3%; p = 0.07). Mean operative time was longer in group I than in group II (79.3 ± 25.3 vs. 53.7 ± 45.3 min; p = 0.02). However, overall hospital stay was shorter in group I than in group II, but with marginal significance (10.8 ± 4.5 vs. 14.7 ± 9.3 days; p = 0.08). Pros and cons were well balanced between the two groups. Decisions on the timing of cholecystectomy after PTGBD should be made based on considerations of patient condition, hospital facilities, and surgical experience.

    Objective Admission hyperglycemia in acute myocardial infarction (MI) is related with increased in-hospital and long term mortality and major cardiac adverse events. We aimed to investigate how admission hyperglycemia affects the short and long term outcomes in elderly patients (> 65 years) after primary percutaneous coronary intervention for ST elevation myocardial infarction. Methods We retrospectively analyzed 677 consecutive elderly patients (mean age 72.2 ± 5.4). Patients were divided into two groups according to admission blood glucose levels. Group 1: low glucose group (LLG), glucose 168 mg/dL. Results In-hospital, long term mortality and in-hospital major adverse cardiac events were higher in the high admission blood glucose group (P 1, post-thrombolysis in MI < 3 and admission blood glucose levels were independent predictors of in-hospital adverse cardiac events (P < 0.001). Conclusions Admission hyperglycemia in elderly patients presented with ST elevation myocardial infarction is an independent predictor of in-hospital major adverse cardiac events and is associated with in-hospital and long term mortality.

Therefore, we aimed to evaluate the prognostic importance of non-O blood groups in patients with STEMI undergoing primary percutaneous coronary intervention (pPCI) METHODS: 1835 consecutive patients who were admitted with acute STEMI between 2010 and 2015 were included and followed-up for a median of 35.6months. The prevalence of hyperlipidemia, total cholesterol, LDL, peak CKMB and no-reflow as well as hospitalization duration were higher in patients with non-O blood groups. Gensini score did not differ between groups. During the in-hospital and long-term follow-up period, MACE, the prevalence of stent thrombosis, non-fatal MI, and mortality were higher in non-O blood groups. In multivariate logistic regression analysis, non-0 blood groups were demonstrated to be independent predictors of in-hospital (OR:2.085 %CI: 1.328-3.274 p=0.001) and long term MACE (OR:2.257 %CI: 1.325-3.759 pblood group compared with O blood group (pblood groups were determined to be significant prognostic indicators of short- and long-term cardiovascular adverse events and mortality in patients with STEMI undergoing pPCI. In conjunction with other prognostic factors, evaluation of this parameter may improve the risk categorization and tailoring the individual therapy and follow-up in STEMI patient population.

    Background: Percutaneous injection of bone cement (acrylic cement) during percutaneous kyphoplasty and vertebroplasty can cause symptomatic or asymptomatic complications due to leakage, extravasation or vascular migration of cement. Purpose: To investigate and to compare the incidence and site of local leakage or complications of bone cement after percutaneous kyphoplasty and vertebroplasty using bone cement. Material and Methods: We retrospectively reviewed 473 cases of percutaneous kyphoplasty or vertebroplasty performed under fluoroscopic guidance. Of the 473 cases, follow-up CT scans that covered the treated bones were available for 83 cases (59 kyphoplasty and 24 vertebroplasty). Results: The rate of local leakage of bone cement was 87.5% (21/24) for percutaneous vertebroplasty and 49.2% (29/59) for kyphoplasty. The most common site of local leakage was perivertebral soft tissue (n=8, 38.1%) for vertebroplasty. The most common site of local leakage was a perivertebral vein (n=7, 24.1%) for kyphoplasty. Two cases of pulmonary cement embolism developed: one case after kyphoplasty and one case after vertebroplasty. Conclusion: Local leakage of bone cement was more common for percutaneous vertebroplasty compared with kyphoplasty (P<0.005). The most common sites of local leakage were perivertebral soft tissue and perivertebral vein.

    Kienböck disease typically presents with wrist pain, swelling, restricted range of motion, and difficulty in performing activities of daily living. Because the etiology and evolution of disease remain unclear, broad ranges of treatments have been designed. Percutaneous cementoplasty is expanding its role for managing painful bone metastases outside the spine. We can draw a parallel between lytic tumoral lesions and Kienbock’s disease. Increasing the strength and rigidity of lunate with cementoplasty can prevent it from collapse, relieve the symptoms associated with the process of avascular necrosis, and increase the wrist range of motion. We report the case of 30-year-old man with a painful stage IIIA Kienböck disease who underwent percutaneous cementoplasty and experienced immediate effective pain relief and recovery of wrist mobility.

    Long-term maintenance of a dermal barrier around a percutaneous prosthetic device remains a common clinical problem. A technique known as Negative Pressure Wound Therapy (NPWT) uses negative pressure to facilitate healing of impaired and complex soft tissue wounds. However, the combination of using negative pressure with percutaneous prosthetic devices has not been investigated. The goal of this study was to develop a methodology to apply negative pressure to the tissues surrounding a percutaneous device in an animal model; no tissue healing outcomes are presented. Specifically, four hairless rats received percutaneous porous coated titanium devices implanted on the dorsum and were bandaged with a semi occlusive film dressing. Two of these animals received NPWT; two animals received no NPWT and served as baseline controls. Over a 28-day period, both the number of dressing changes required between the two groups as well as the pressures were monitored. Negative pressures were successfully applied to the periprosthetic tissues in a clinically relevant range with a manageable number of dressing changes. This study provides a method for establishing, maintaining, and quantifying controlled negative pressures to the tissues surrounding percutaneous devices using a small animal model.

    A 72-year-old man who had undergone a total gastrectomy with a Roux-en-Y esophagojejunostomy for gastric cancer 6 years earlier presented to our hospital with massive hematemesis and melena. Endoscopic examination indicated esophageal varices with cherry-red spots and hemorrhage arising from beyond the anastomosis. Abdominal contrast-enhanced computed tomography and angiography revealed a dilated vein in the elevated jejunal limb supplying the varices. Percutaneous trans-hepatic obliteration (PTO) of the varices through the jejunal vein was performed using microcoils, ethanolamine oleate, and gelatin sponge cubes. Ten days after the procedure, endoscopic examination revealed reduction and thrombosis of the varices. We consider PTO to be an effective alternative method for treating ruptured esophagojejunal varices after total gastrectomy

    Acute suppurative cholangitis is a severe inflammatory process of the bile duct occurred as result of partial or complete obstruction of the bile duct, and may manifest clinically severe form of disease, rapidly deteriorating to life-threatening condition. We analyzed emergency percutaneous transhepatic biliary drainage in 20 patients of acute suppurative cholangitis with biliary sepsis to evaluate the therapeutic effect and complication of the procedure. The underlying cause were 12 benign disease(stones) and eight malignant tumors and among eight malignant tumors, bile duct stones(n=4) and clonorchiasis(n=1) were combined. Percutaneous transhepatic biliary drainage was performed successfully in 17 of 20 patients resulting in improvement of general condition and failed in three patients. The procedure were preterminated due to the patient's condition in two and biliary-proto fistula was developed in one. After biliary decompression by percutaneous transhepatic biliary drainage, effective and successful elective surgery was performed in nine cases, which were seven biliary stones and two biliary cancer with stones. Our experience suggest that emergency percutaneous transhepatic biliary drainage is an initial and effective treatment of choice for acute suppurative cholangitis with sepsis and a safe alternative for nonsurgical treatment

    The aim of this study is to evaluate the efficacy of emergency percutaneous treatment in patients with surgical bile duct injury (SBDI). From May 2004 to May 2007, 11 patients (five men, six women; age range 26-80 years; mean age 58 years) with a critical clinical picture (severe jaundice, bile peritonitis, septic state) due to SBDI secondary to surgical or laparoscopic procedures were treated by percutaneous procedures. We performed four ultrasound-guided percutaneous drainages, four external-internal biliary drainages, one bilioplasty, and two plastic biliary stenting after 2 weeks of external-internal biliary drainage placement. All procedures had 100% technical success with no complications. The clinical emergencies resolved in 3-4 days in 100% of cases. All patients had a benign clinical course, and reoperation was avoided in 100% of cases. Interventional radiological procedures are effective in the emergency management of SBDI since they are minimally invasive and have a high success rate and a low incidence of complications compared to the more complex and dangerous surgical or laparoscopic options.

    Full Text Available Due to the ageing population and raised life expectancy, elderly patients are increasingly referred for percutaneous coronary intervention (PCI during acute coronary syndromes (ACS. Bleeding complications are not infrequent during ACS, occurring in 2-5% of patients with prognostic and economic consequences. In particular, periprocedural bleeding and vascular complications are associated with worse clinical outcome, prolonged hospital stay and increased short- and long-term mortality, especially in elderly patients with acute coronary syndromes. We report the case of an 83-year old female referred to our hospital because of non-ST segment elevation myocardial infarction with high bleeding risk and unsuitable radial artery undergoing transulnar sheathless PCI during bivalirudin infusion. The clinical, technical, pharmacological and prognostic implications are discussed.

The reflow of the involved vessel in pPCI procedure, stent thrombosis and major adverse cardiac events (MACE were comparatively analyzed in the two groups during hospital stay and 12-month follow-up period. Results Although the success rate of TA procedure was significantly lower in TA group compared with that in control group (P<0.001, both the TIMI flow grade ≥2 after TA procedure and stent implantation occurred more frequently in TA group than in control group (P<0.05. The rates of MACE and stent thrombosis showed no difference between two groups during in-hospital and 12-month follow-up period (P>0.05. But the rates of total MACE and target vessel revascularization were significantly higher in control group than in TA group (P=0.04.

    The authors of this paper report seven cases of percutaneous destruction of osteoid osteoma. All patients complained of typical pain lasting for several months. In each case, finding of plain radiography, bone scintigraphy, and CT were strongly suggestive of an osteoid osteoma. All the lesions were located on the lower limb (five femoral and two tibial). Under general anesthesia, the nidus was drilled through a trocar inserted percutaneously with CT guidance. Patients were discharged 1-3 days after the procedure with no residual pain, and they are still asymptomatic 18-33 months later, with normal scintigraphic and CT studies. Histologic confirmation was allowed by technical improvement of the method in the last four cases

    Full Text Available Introduction. Adult spinal deformity (ASD surgeries carry significant morbidity, and this has led many surgeons to apply minimally invasive surgery (MIS techniques to reduce the blood loss, infections, and other peri-operative complications. A spectrum of techniques for MIS correction of ASD has thus evolved, most recently the application of percutaneous iliac screws. Methods. Over an 18 months 10 patients with thoracolumbar scoliosis underwent MIS surgery. The mean age was 73 years (70% females. Patients were treated with multi-level facet osteotomies and interbody fusion using expandable cages followed by percutaneous screw fixation. Percutaneous iliac screws were placed bilaterally using the obturator outlet view to target the ischial body. Results. All patients were successfully instrumented without conversion to an open technique. Mean operative time was 302 minutes and the mean blood loss was 480 cc, with no intraoperative complications. A total of 20 screws were placed successfully as judged by CT scanning to confirm no bony violations. Complications included: two asymptomatic medial breaches at T10 and L5, and one patient requiring delayed epidural hematoma evacuation. Conclusions. Percutaneous iliac screws can be placed safely in patients with ASD. This MIS technique allows for successful caudal anchoring to stress-shield the sacrum and L5-S1 fusion site in long-segment constructs.

    Percutaneous biliary drainage is an important technique for palliative therapy of obstructive biliary disease and diagnostic information. The purpose of this study is to review and evaluate the experiences of ultrasound-guided percutaneous transhepatic biliary drainage. Ultrasound-guided percutaneous transhepatic biliary drainage was performed on 146 occasions in 134 patients. The causes of biliary obstruction were: benign diseases (19 cases, 14.2%) such as bile duct stones or stricture, cholangiocarcinoma (37 cases, 27.6%), pancreatic carcinoma (35 cases, 26.1%), metastasis (22 cases, 16.5%), gall bladder cancer (14 cases, 10.4%), ampulla of Vater cancer (4 cases, 3.0%), hepatocellular carcinoma (3 cases, 2.2%). Retrospectively reviewing medical records, we found out frequency of external or external/internal biliary drainages, puncture of left or right hepatic duct, and presence of bileinfection. Ultrasound-guided percutaneous transhepatic biliary drainage was compared with conventional biliary drainage of previous reports on the basis of frequency of complications. External (124 procedures, 84.9%) and external/internal biliary drainage (22 procedures, 15.1%) were carried out by puncture of dilated right (59.6%) or left (40.4%) intrahepatic duct. Sixty-nine complications occurred in 47 patients. Catheter related complications (33/69, 47.8%) were most common: catheter dislodgement (17/69, 24.6%), malfunction (9/69, 13.1%), leakage (7/69, 10.1%). Other minor complications such as simple fever (16/69, 23.2%), cholangitis (7/69, 10.1%), hemobilia (4/69, 5.8%), biloma (2/69, 2.9%) and wound infection (1/69, 1.5%) occurred. Major complications including sepsis (4/69, 5.8%) and bile peritonitis (2/69, 2.9%) were also noted. Puncture-related complications such as hemobilia, biloma and bile peritonitis occurred in 8 cases (5.5%). Comparing with conventional X-ray guided drainage, ultrasound-guided percutaneous transhepatic biliary drainage is a safe procedure for

    Percutaneous absorption in vivo through the skin of the feet of the red-winged blackbird (Agelaius phoeniceus) has been investigated. Absorption after 18-24 hours exposure to 0.01 M solutions of salicylic acid, caffeine, urea, 2,4-D, dieldrin, diethylstilbesterol, and DDT was measured. Of these, only DDT and diethylstilbesterol were not absorbed to a measurable degree. The solvents ethanol, dimethylsulfoxide (DMSO), and vegetable oil were compared with water in their effects on the absorption ofcaffeine, urea, and salicylic acid. Ethanol, DMSO,and oil each decreased percutaneous absorption of salicylic acid. DMSO increased absorption of caffeine, and ethanol had no effect on it. Neither DMSO nor ethanol affected penetration of urea. Partition coefficients (K) (epidermis/water) were determined for all seven penetrants. Compounds with higher values of K showed lower percutaneous absorption. These findings suggest that K may be useful to predict percutaneous absorption in vivo. It appears unlikely that percutaneous absorption contributes greatly to the body burden of 2,4-D and dieldrin in A. phoeniceus.

    To determine the clinical efficacy of sonographically-guided percutaneous bone drilling of the lateral epicondyle (LE) for the treatment of patients with LE. We included 24 patients with LE who reported pain in this study. All patients underwent sonographically-guided percutaneous bone drilling of the lateral epicondyle. Follow-up sonography and physical examinations were performed 1, 3 and 6 months after the procedure. The outcome measures included sonographic findings, visual analogue scale (VAS) score, maximum voluntary grip strength (MVGS) and patient-related tennis elbow evaluation (PRTEE) score. None of the patients had immediate complications during the procedure. The area of the extensor carpi radialis brevis (ECRB) tears decreased significantly at 1 month and declined gradually over the remaining 5 months of the study (p LE that can be performed in an outpatient setting. • Percutaneous drilling of the lateral condyle is effective for the treatment of LE. • The area of ECRB tears can be measured by US-guided saline injection. • US-guided percutaneous drilling is a quick and safe treatment option for LE.

    Full Text Available Patent ductus arteriosus is treated according to its indications conservatively with medications or by surgical closure; the latter was traditionally performed by an open technique, then later, the percutaneous approach was developed for selected cases and finally, in recent years, it has been done by thoracoscopic surgery with success challenging percutaneous results. However, at our hospital, this had not been tried before. We present the case of a female patient who met the ideal criteria for this procedure to be performed and in whom it was successfully accomplished without complications; hence our report, motivated by the historical importance and as a baseline for future cases.

    Percutaneous arterial embolization in the treatment of liver trauma. Liver trauma requires emergency therapy. Because it is highly vascular and because of its location, the hemostasis is difficult to achieve. The main causes of death associated to liver trauma are due to prolonged hipovolemia. The current forms of surgical treatment of liver wounds are associated with a high morbidity rate. In some hepatic injuries, hemorrage is so massive that operative control of bleeding is necessary, bu t in most cases, particularly in blunt trauma, an angiographic approach with diagnosis and embolotherapy is preferable. Six patients with blunt or perforating hepatic trauma were managed with percutaneous arterial embolization. Hemostasis was achieved immediately in all of them withoyt recurrence. Surgical intervention with additional trauma was thus avoided, decreasing the morbidity rate. The percutaneous arterial embolization presents an efficient alternative in the management of hemorrage due to liver trauma, being particularly useful in the poor risk patient. (author) [pt

    There are many treatment options in high-flow priapism. Those mentioned most often are watchful waiting, Doppler-guided compression, endovascular highly selective embolization, and surgery. We present a case of high-flow priapism in a 57-year-old man treated by percutaneous direct puncture embolization of a post-traumatic left cavernosal arteriovenous fistula using N-butyl-cyanoacrylate. Erectile function was preserved during a 12-month follow-up. No patients with percutaneous direct puncture embolization for high-flow priapism have been reported previously. Percutaneous direct puncture embolization is a potentially useful and safe method for management of high-flow priapism.

    Access for endovascular repair of abdominal aortic aneurysms (EVAR) is obtained through surgical cutdown or percutaneously. The only devices suitable for percutaneous closure of the 20 French arteriotomies of the common femoral artery (CFA) are the Prostar(™) and Proglide(™) devices (Abbott Vascular). Positive effects of these devices seem to consist of a lower infection rate, and shorter operation time and hospital stay. This conclusion was published in previous reports comparing techniques in patients in two different groups (cohort or randomized). Access techniques were never compared in one and the same patient; this research simplifies comparison because patient characteristics will be similar in both groups. Percutaneous access of the CFA is compared to surgical cutdown in a single patient; in EVAR surgery, access is necessary in both groins in each patient. Randomization is performed on the introduction site of the larger main device of the endoprosthesis. The contralateral device of the endoprosthesis is smaller. When we use this type of randomization, both groups will contain a similar number of main and contralateral devices. Preoperative nose cultures and perineal cultures are obtained, to compare colonization with postoperative wound cultures (in case of a surgical site infection). Furthermore, patient comfort will be considered, using VAS-scores (Visual analog scale). Punch biopsies of the groin will be harvested to retrospectively compare skin of patients who suffered a surgical site infection (SSI) to patients who did not have an SSI. The PiERO trial is a multicenter randomized controlled clinical trial designed to show the consequences of using percutaneous access in EVAR surgery and focuses on the occurrence of surgical site infections.

    The objective of the present study was to determine the frequency of gas retention in the renal vein following carbon dioxide intraosseous venography in the prone position and, while citing references, to examine its onset mechanisms. All percutaneous vertebroplasties performed at our hospital from January to December 2005 were registered and retrospectively analyzed. Of 43 registered procedures treating 79 vertebrae, 28 procedures treating 54 vertebrae were analyzed. Vertebral intraosseous venography was performed using carbon dioxide as a contrast agent in all percutaneous vertebroplasty procedures. In preoperative and postoperative vertebral CT, gas retention in the renal vein and other areas was assessed. Preoperative CT did not show gas retention (0/28 procedures; 0%). Postoperative CT confirmed gas retention in the renal vein in 10 of the 28 procedures (35.7%). Gas retention was seen in the right renal vein in 8 procedures (28.6%), in the left renal vein in 5 procedures (17.9%), in the left and right renal veins in 3 procedures (10.7%), in vertebrae in 22 procedures (78.6%), in the soft tissue around vertebrae in 14 procedures (50.0%), in the spinal canal in 12 procedures (42.9%), and in the subcutaneous tissue in 5 procedures (17.9%). In conclusion, in our study, carbon dioxide gas injected into the vertebra frequently reached and remained in the renal vein.

    Remote ischaemic preconditioning attenuates cardiac injury at elective surgery and angioplasty. We tested the hypothesis that remote ischaemic conditioning during evolving ST-elevation myocardial infarction, and done before primary percutaneous coronary intervention, increases myocardial salvage. 333 consecutive adult patients with a suspected first acute myocardial infarction were randomly assigned in a 1:1 ratio by computerised block randomisation to receive primary percutaneous coronary intervention with (n=166 patients) versus without (n=167) remote conditioning (intermittent arm ischaemia through four cycles of 5-min inflation and 5-min deflation of a blood-pressure cuff). Allocation was concealed with opaque sealed envelopes. Patients received remote conditioning during transport to hospital, and primary percutaneous coronary intervention in hospital. The primary endpoint was myocardial salvage index at 30 days after primary percutaneous coronary intervention, measured by myocardial perfusion imaging as the proportion of the area at risk salvaged by treatment; analysis was per protocol. This study is registered with ClinicalTrials.gov, number NCT00435266. 82 patients were excluded on arrival at hospital because they did not meet inclusion criteria, 32 were lost to follow-up, and 77 did not complete the follow-up with data for salvage index. Median salvage index was 0.75 (IQR 0.50-0.93, n=73) in the remote conditioning group versus 0.55 (0.35-0.88, n=69) in the control group, with median difference of 0.10 (95% CI 0.01-0.22; p=0.0333); mean salvage index was 0.69 (SD 0.27) versus 0.57 (0.26), with mean difference of 0.12 (95% CI 0.01-0.21; p=0.0333). Major adverse coronary events were death (n=3 per group), reinfarction (n=1 per group), and heart failure (n=3 per group). Remote ischaemic conditioning before hospital admission increases myocardial salvage, and has a favourable safety profile. Our findings merit a larger trial to establish the effect of remote

    Full Text Available Retroperitoneal abscess is a serious complication of diverticular disease. Its management involves several options, ranging from conservative management to surgery. Elective colectomy is most often thought to be mandatory after a percutaneous drainage given the high rate of recidive. However, in patients with high risk for surgery, percutaneous drainage is often the main therapeutic alternative. We report a case of a 80-year-old woman, who was diagnosed to have a retroperitoneal abscess complicating a sigmoid diverticulitis. Ultrasound-guided percutaneous drainage allowed to drain 1500cc of pus and gas. The cytobacteriological examination was positive for: Streptococcus spp and Alkalescens dispar. The therapeutic outcomes were uneventful and despite we did not realize a colectomy because the patient was at high risk for surgery, there was no recidive after a 2-year-follow-up period. Percutaneous drainage can be a therapeutic alternative in patients with high risk for surgery in diverticular abscess of big size.

    In cattle, percutaneous needle liver biopsy is used for scientific examination of liver metabolism. The impact of the biopsy procedure is, however, poorly investigated. Our aim was to examine the behaviour of dairy cows during and after liver biopsy. Data were collected from 18 dry cows....... Percutaneous needle liver biopsies (after administration of local anaesthesia (2% Procaine)) and blood samples were taken during restraining. During the control treatment, animals were restrained and blood sampled. During the biopsy procedure, cows showed increased restlessness (P = 0.008), frequency of head...... behavioural changes for up to 19 h – and particularly for behaviour previously associated with pain. Even though the exact welfare impact of percutaneous needle liver biopsies in cows is not known, and the magnitude of the behavioural changes was limited, pain always has negative effects on animal welfare...

    OBJECTIVE During the mini-open posterior corpectomy, percutaneous instrumentation without fusion is performed above and below the corpectomy level. In this study, the authors' goal was to compare the perioperative and long-term implant failure rates of patients who underwent nonfused percutaneous instrumentation with those of patients who underwent traditional open instrumented fusion. METHODS Adult patients who underwent posterior thoracic corpectomies with cage reconstruction between 2009 and 2014 were identified. Patients who underwent mini-open corpectomy had percutaneous instrumentation without fusion, and patients who underwent open corpectomy had instrumented fusion above and below the corpectomy site. The authors compared perioperative outcomes and rates of implant failure requiring reoperation between the open (fused) and mini-open (unfused) groups. RESULTS A total of 75 patients were identified, and 53 patients (32 open and 21 mini-open) were available for followup. The mean patient age was 52.8 years, and 56.6% of patients were male. There were no significant differences in baseline variables between the 2 groups. The overall perioperative complication rate was 15.1%, and there was no significant difference between the open and mini-open groups (18.8% vs 9.5%; p = 0.359). The mean hospital stay was 10.5 days. The open group required a significantly longer stay than the mini-open group (12.8 vs 7.1 days; p open and mini-open groups at 6 months (3.1% vs 0.0%, p = 0.413), 1 year (10.7% vs 6.2%, p = 0.620), and 2 years (18.2% vs 8.3%, p = 0.438). The overall mean follow-up was 29.2 months. CONCLUSIONS These findings suggest that percutaneous instrumentation without fusion in mini-open transpedicular corpectomies offers similar implant failure and reoperation rates as open instrumented fusion as far out as 2 years of follow-up.

    Abstract The location of the caudate lobe and its complex anatomy make caudate lobectomy and radiofrequency ablation (RFA) under ultrasound guidance technically challenging. The objective of the exploratory study was to introduce a novel modality of treatment of lesions in caudate lobe and discuss all details with our experiences to make this novel treatment modality repeatable and educational. The study enrolled 39 patients with liver caudate lobe tumor first diagnosed by computerized tomography (CT) or magnetic resonance imaging (MRI). After consultation of multi-disciplinary team, 7 patients with hepatic caudate lobe lesions were enrolled and accepted CT-guided percutaneous step-by-step RFA treatment. A total of 8 caudate lobe lesions of the 7 patients were treated by RFA in 6 cases and RFA combined with percutaneous ethanol injection (PEI) in 1 case. Median tumor diameter was 29 mm (range, 18–69 mm). A right approach was selected for 6 patients and a dorsal approach for 1 patient. Median operative time was 64 min (range, 59–102 min). Median blood loss was 10 mL (range, 8-16 mL) and mainly due to puncture injury. Median hospitalization time was 4 days (range, 2–5 days). All lesions were completely ablated (8/8; 100%) and no recurrence at the site of previous RFA was observed during median 8 months follow-up (range 3–11 months). No major or life-threatening complications or deaths occurred. In conclusion, percutaneous step-by-step RFA under CT guidance is a novel and effective minimally invasive therapy for hepatic caudate lobe lesions with well repeatability. PMID:26426638

    Chylopericardium rarely occurs in pediatric patients, but when it does it is most often a result of lymphatic injury during cardiothoracic surgery. Primary idiopathic chylopericardium is especially rare, with few cases in the pediatric literature. We report a 10-year-old boy who presented with primary idiopathic chylopericardium after unsuccessful initial treatment with surgical lymphatic ligation and creation of a pericardial window. Following readmission to the hospital for a right-side chylothorax resulting from the effluent from the pericardial window, he had successful treatment by interventional radiology with percutaneous thoracic duct embolization. This case illustrates the utility of thoracic duct embolization as a less-invasive alternative to surgical thoracic duct ligation, or as a salvage procedure when surgical ligation fails. (orig.)

    Purpose Ultrasound Guided Percutaneous Kidney Biopsy (UGPKB) plays a major role in diagnosis of renal tumours. There seems to be little consensus regarding post-biopsy observation period. We aim to identify complications in UGPKB among outpatients with a suspected malignant renal lesion as well...... as the timing of onset of these complications, helping to clarify the optimal observation period. Many studies in this field suggest a lower complication risk for outpatients compared to hospitalized patients. In the latter group, an observation period of 24h after biopsy is often recommended. Material...... discrepancy. Results As for one third of the patients, analysed up until now, we find a total of one major complication and a few minor, all arisen within less than 6 hours after biopsy. Conclusions Rates of both major and minor complications in UGPKB are very low suggesting a shorter observation period...

    Percutaneous treatments are used in the therapy of small- to medium-sized hernias of intervertebral discs to reduce the intradiscal pressure in the nucleus and theoretically create space for the herniated fragment to implode inward, thus reducing pain and improving mobility and quality of life. These techniques involve the percutaneous removal of the nucleus pulposus by using a variety of chemical, thermal, or mechanical techniques and consist of removal of all or part of nucleus pulposus to induce more rapid healing of the abnormal lumbar disc. These guidelines are written to be used in quality improvement programs for assessing fluoroscopy- and/or computed tomography-guided percutaneous intervertebral disc ablative techniques.

    Chronic subdural hematoma is a frequently encountered entity in neurosurgery in particular in elderly patients. There in a high variance in the treatment in literature. We report our experience of percutaneous evacuation of chronic subdural hematoma in 28 patients. From January 2007 to July 2009, 28 patients underwent percutaneous evacuation. 27 of the 28 patients (96.4%) became asymptomatic or improved clinically. Six weeks later, the scan showed the hematoma had completely disappeared in 18 of the cases. We did not have any postoperative infection. Treatment of chronic subdural hematoma using a percutaneous operative technique is a minimally invasive method with sufficient outcome and a therapeutic alternative to the craniotomy.

    Approximately 10% of patients with lateral epicondylitis go on to have surgical treatment; however, multiple surgical treatment options exist. The purpose of this study was to review the literature for the clinical outcomes of open, arthroscopic, and percutaneous treatment of lateral epicondylitis. The authors hypothesized that the clinical outcome of all 3 analyzed surgical treatments would be equivalent. A systematic review was performed using PubMed, Cochrane Central Register of Controlled Trials, and Google Scholar in July 2016 to compare the functional outcome, pain, grip strength, patient satisfaction, and return to work at 1-year follow-up for open, arthroscopic, and percutaneous treatment of lateral epicondylitis. Six studies (2 Level I and 4 Level II) including 179 elbows (83 treated open, 14 arthroscopic, 82 percutaneous) were analyzed. Three outcome measures (Disabilities of the Arm, Shoulder, and Hand [DASH] score, visual analog scale [VAS], and patient satisfaction) were reported for more than one category of surgical technique. Of these, the authors noted no clinically significant differences between the techniques. This is the first systematic review looking at high-level evidence to compare open, percutaneous, and arthroscopic techniques for treating lateral epicondylitis. There are no clinically significant differences between the 3 surgical techniques (open, arthroscopic, and percutaneous) in terms of functional outcome (DASH), pain intensity (VAS), and patient satisfaction at 1-year follow-up.

    The treatment of unicameral bone cyst varies from percutaneous needle biopsy, aspiration and local injection of steroid, autologous bone marrow, or demineralized bone matrix to curettage and open bone-grafting. The purpose of this study was to compare the results of open chip allogeneic bone graft versus percutaneous injection of demineralized bone powder with autogenous bone marrow in management of calcaneal cysts. Twenty-three calcaneal unicameral cysts in 20 patients were treated. Lyophilized irradiated chip allogeneic bone (CAB) and autogenous bone marrow were used for treatment of 13 cysts in 11 patients, and 10 cysts in 9 patients were treated with percutaneous injection of irradiated allogeneic demineralized bone powder (DBP) and autogenous bone marrow. There were 11 males and 9 female patients with mean age of 17 years. The patients were followed for an average of 49.4 months. Complete healing was achieved in 9 cysts treated with chip allogeneic bone and in 5 cysts treated with powdered bone. Four cysts treated with CAB and 3 cysts treated with DBP healed with a defect. Two cysts treated with powdered bone and autogenous bone marrow were classified as persistent. No infections or pathological fractures were observed during the followup period. Percutaneous injection of a mixture of allogeneic bone powder with autogenous bone marrow is a minimal invasive method and could be an effective alternative in the treatment of unicameral calcaneal bone cysts. The postoperative morbidity was low, the hospital stay was brief, and patient's comfort for unrestricted activity was enhanced.

    The aim of this study was to systematically compare the perioperative outcomes of percutaneous nephrolithotomy in patients with or without previous ipsilateral open renal surgery (POS). Systematic searches of the PubMed, Web of Science and Cochrane Library databases were used to identify relevant studies, and, following literature screening and data extraction, a meta-analysis was performed. 17 retrospective cohort studies involving 4833 procedures (4784 patients) were included. No statistically significant differences were observed between patients with or without POS in terms of supracostal access; single/multiple tracts; metal dilator need; time required to access the collecting system; fluoroscopic duration; demand for analgesics; hospital stay; final stone-free rate; and risk of developing certain complications (eg, fever, haemorrhage, haemo/hydro/pneumothorax, blood transfusion, urinary tract infection and sepsis) as well as regarding the risk of total complications. Patients with POS, however, had a greater drop in haemoglobin (weighted mean difference (WMD), 1.78 g/L; 95% CI 1.09 to 2.47; pPOS also had a lower initial stone-free rate (RR, 0.96; 95% CI 0.92 to 0.99; p=0.007) and more secondary treatment (RR, 1.61; 95% CI 1.09 to 2.37; p=0.02). Sensitivity analysis produced comparable results except for differences in operative time and initial stone-free rate, which did, however, prove to be statistically insignificant (p=0.16 and 0.69, respectively). Current evidence suggests that percutaneous nephrolithotomy in patients with POS is associated with a significantly greater drop in haemoglobin, higher risk of requiring angiographic embolisation and auxiliary procedures, potentially longer operative time, and lower initial stone-free rate than percutaneous nephrolithotomy in patients without POS.

    Objective: To compare the sensitivity between forceps biopsy and brushing, and to explore a feasible approach to pathological diagnosis of the obstructive jaundice. Methods: 92 consecutive patients with obstructive jaundice underwent transluminal forceps biopsy and brushing during percutaneous transhepatic cholangiography and percutaneous transhepatic cholangiodrainage. The technique was performed through a preexisting percutaneous transhepatic tract with multiple specimens obtained after passing the forceps biopsy or brush into a 8-French sheath. Finally the specimens were fixed with formalin for pathologic or cytologic diagnosis. Results: The histopathologic diagnosis was acquired in 81 out of 92 patients with forceps biopsy reaching the successful rate of 97.83%. Sensitivity of forceps biopsy in 92 patients was higher than that of brush in 84 patients (88.04% vs 76.19% χ 2 =4.251, P= <0.05). Conclusions: Percutaneous transhepatic cholangiobiopsy is a simple technique with minimal invasion, high sensitivity and worthy to be used spread extensively. Percutaneous transluminal brush cytology is also an useful method for establishing a diagnosis of cholangiocarcinoma. (authors)

    Objective: To evaluate the safety and effectiveness of percutaneous gastrostomy (PRG) and gastrojejunostomy (PRGJ) under fluoroscopic guidance, and to discuss its technical manipulation, the indications and contraindications as well as the complications. Methods: During the period from May 2002 to June 2010 in authors' hospital fluoroscopically-guided PRG or PRGJ was carried out in 40 patients. The clinical data were retrospectively analyzed. With Seldinger technique and under fluoroscopic guidance, a 14 F radiopaque gastrostomy or gastrojejunostomy feeding catheter was successfully placed. The indications, operation procedures, clinical success rate, procedure-related complications, and tube indwelling time, etc. were discussed and analyzed. Results: PRG was conducted in 30 patients. The reasons for performing PRG included neurologic disease (n=13), recurrent aspiration pneumonia (n=6), gastroesophageal reflux due to disfunction of gastrointestinal tract (n=3), subtotal gastrectomy (n=2), esophagomediastinal fistula (n=1) and esophageal carcinoma (n=5). PRGJ was carried out in 10 patients. The disorders included bulbar paralysis (n=3), malignant duodenal obstruction (n=4) and previous gastrostomy-related complications (n=3). Two anchors were used in all patients receiving PRG or PRGJ. Clinical success was achieved in all study patients. No procedure-related or severe complications occurred. Minor complications were observed in four patients (10%), which included local soft tissue infection (n=1), severe puncture site pain (n=1), gastrostomy tube dislodgement (n=1) and obstruction of gastrojejunostomy tube (n=1). During the follow-up period, no aggravation of gastroesophageal reflux or aspiration pneumonia was observed in all patients. The tube indwelling time was 115 to 585 days (mean of 150 days) after tube placement. Conclusion: Fluoroscopically-guided percutaneous gastrostomy or gastrojejunostomy is a safe, simple and minimally-invasive technique. This

    Tumor-induced osteomalacia is a rare condition usually caused by benign mesenchymal tumors. When the tumor can be found, patients are usually managed by wide excision of the tumor. We report a 51-yr-old male with clinical and biochemical evidence of tumor-induced osteomalacia caused by a mesenchymal tumor in the right iliac bone. He declined surgery and appears to have been successfully managed by computed tomography-guided percutaneous ethanol ablation and percutaneous cryoablation. Our patient appears to have had an excellent clinical and biochemical response to computed tomography-guided percutaneous ethanol ablation and percutaneous cryoablation. We found one prior case of image-guided ablation using radiofrequency ablation for tumor-induced osteomalacia. Although the standard treatment for tumor-induced osteomalacia is wide excision of the tumor, image-guided ablation may be an option in patients who cannot have appropriate surgery or who decline surgery.

    Purpose: To report on the frequency and treatment of arterial complications due to percutaneous transhepatic biliary drainage (PTBD).Materials: Lesions of the intrahepatic artery were encountered in 10 of 525 patients treated by PTBD (2%). Hemobilia followed in 9 patients and subcapsular hematoma in 1. Seven patients had a benign biliary stenosis and 3 had a malignant stenosis.Results: The bleeding resolved spontaneously in 3 patients. In 7 it required arterial embolization, which was successfully achieved either through the percutaneous catheter (n= 3) or by arteriography (n= 4).Conclusion: Arterial bleeding is a relatively rare complication of PTBD that can easily be treated by selective arterial embolization when it does not resolve spontaneously. In this series its frequency was much higher (16%) when the stenosis was benign than when it was malignant (0.6%)

    This study was intended to investigate the healing properties of open and percutaneous techniques in a rabbit model and compare histological, electron microscopical, and biomechanical findings of the healed tendon between the groups. Twenty-six rabbits were randomly assigned to two groups of thirteen rabbits each. Percutaneous tenotomy of the Achilles tendon (AT) was applied through a stab incision on the right side 1.5 cm above the calcaneal insertion in all animals. Using the same Bunnell suture, the first group was repaired with the open and the second group was repaired with the percutaneous method. ATs were harvested at the end of eight weeks for biomechanical and histological evaluation. When the sections were evaluated for fibrillar density under electron microscopy, it was noted that fibrils were more abundant in the percutaneous repair group. The tendon scores in the percutaneous group were less than the open group indicating closer histological morphology to normal. The difference was not significant (p=0.065). The mean force to rupture the tendon was 143.7± 9.5 N in percutaneous group and 139.2±8.2 N in the open group. The difference was not significant (p=0.33). Percutaneous techniques provide as good clinical results as the open techniques do. The healing tendon shows better findings in histological and electron microscopical level with percutaneous technique.

    To evaluate the clinical efficacy, safety, and costs of percutaneous occlusive balloon catheter-assisted ureteroscopic lithotripsy (POBC-URSL) for large impacted proximal ureteral calculi. 156 patients with impacted proximal ureteral stones ≥1.5 cm in size were randomized to ureteroscopic lithotripsy (URSL), POBC-URSL, and percutaneous nephrolithotomy (PNL) group between May 2010 and May 2013. For URSL, the calculi were disintegrated with the assistance of anti-retropulsion devices. POBC-URSL was performed with the assistance of an 8F percutaneous occlusive balloon catheter. PNL was finished with the combination of an ultrasonic and a pneumatic lithotripter. A flexible ureteroscope and a 200 μm laser fiber were used to achieve stone-free status to a large extent for each group. Variables studied were mean operative time, auxiliary procedure, postoperative hospital stay, operation-related complications, stone clearance rate, and treatment costs. The mean lithotripsy time for POBC-URSL was shorter than URSL, but longer than PNL (42.6±8.9 minutes vs 66.7±15.3 minutes vs 28.1±6.3 minutes, p=0.014). The auxiliary procedure rate and postoperative fever rate for POBC-URSL were significantly lower than URSL and comparable to PNL (pPNL (98.1% vs 75.0% vs 96.2%, pPNL group and similar to URSL group (p=0.016, pPNL.

    Diabetes mellitus is a 21st century pandemic. Due to life-span prolongation combined with the increased rate of diabetes, a growing population of patients is afflicted with neuropathic foot deformities. Traditional operative repair of these deformities is associated with a high complication rate and relatively common infection incidence. In recent years, in order to prevent these complications, percutaneous deformity correction methods were developed. Description of experience accumulated in treating 20 consecutive patients with diabetic neuropathic foot deformities treated in a percutaneous fashion. A consecutive series of patients treated at our institute for neuropathic foot deformity was assessed according to a standard protocol using the AOFAS forefoot score and the LUMT score performed at baseline as well as at 6 months and 12 months. Treatment related complications were monitored. All procedures were performed in an ambulatory setting using local anesthesia. A total of 12 patients had soft tissue corrections, and 8 had a combined soft tissue and bone correction. Baseline AOFAS score was 48±7 and improved to 73±9 at six months and 75±7 at one year. LUMT score in 11 patients with a chronic wound decreased from 22±4 to 2±1 at one year post-op. One patient required hospitalization due to post-op bleeding. Percutaneous techniques allow deformity correction of diabetic feet, including those with open wounds in an ambulatory setting with a low complication rate.

    To evaluate the effectiveness of percutaneous catheter drainage in treatment of the lung abscess. We treated the lung abscesses in 14 patients (12 mean, 2 women), who did not respond to medical therapy, by percutaneous catheter drainage under fluoroscopic or ultrasound guidance. One abscess due to infacted bulla was managed by combination treatment with alcohol sclerosing therapy. Patients were followed by serial chest radiographs every three days and the amount of drained or aspirated pus evaluated. The treatment effect and recurrence were followed by chest PA and lateral chest at one week after removal of drainage catheter. Thirteen patients (93%) recovered clinically and radiologically within 3 days. In 10 patients, drainage catheter could be removed within 2 weeks, and three patients, the catheter was kept longer. Most complications were mild; vague to moderate chest pain (n = 14), mild hemoptysis (n = 2), and pneumothorax (n = 1). One man who suffered from far advanced pulmonary tuberculosis died of asphyxia caused by massive hemoptysis 16 days after percutaneous drainage. Percutaneous catheter drainage is a safe and effective method for treating lung abscess.

    To review the effectiveness and complication of percutaneous cholecystostomy (PCCS). We performed PCCS in 60 patient who presented with acute cholecystitis. The causes of acute cholecystitis were as follows; acalculous cholecystitis(n=8), calculous cholecystitis(n=23), GB hydrops (n=3), GB empyema(n=15), septic cholangitis(n=11). Of 60 patients, 36 patients had high risk factor for cholecystectomy; underlying malignancy(n=13), severe trauma(n=6). Cholecystostomy was done under ultrasonographic and fluoroscopic guide. The cholecystostomy was successfully in 59 patients, and failed in 1 patient. 15 patients improved without other procedure. 16 patients underwent cholecystectomy after improvement of their general condition. Severe complications of PCCS are as follows; bile peritonitis(n=6), hemoperitoneum(n=1), subphrenic abscess(n=1). Mild complication, such as pain, occurred in most patients. Emergency operation was done in one patient who developed bile peritonitis. Cholecystostomy is effective and safe, especially in cases of inoperable patients who represent acute cholecystitis. Percutaneous cholecystostomy may substitute surgical cholecystostomy.

    The aim of this study was to estimate the feasibility and therapeutic effectiveness of percutaneous microwave ablation in the treatment of hypersplenism in cirrhosis. Forty-one cirrhosis patients with hypersplenism were treated with ultrasonography-guided percutaneous microwave ablation between February 2007 and August 2011. Peripheral blood cell counts, portal vein diameter, splenic vein diameter, and blood flow of splenic vein were evaluated before and after the operation, and complications of the treatment were also investigated. All patients were followed up for 24 months. The levels of platelets and white blood cells were increased, while the splenic vein diameter narrowed gradually after the therapy and 24 months later. Moreover, patients received percutaneous microwave ablation had much lower splenic venous flow velocity. The portal vein diameter did not change significantly 6 months after the treatment, although it narrowed gradually within 3 months after the treatment. Furthermore, no complications such as uncontrollable bleeding, splenic abscess, spleen rupture, and damage in surrounding organ happened after the therapy. Graded percutaneous microwave ablation, as a minimally invasive therapy, could damage the spleen, increase the levels of platelets and white blood cells, and reduce portal hypertension effectively without serious complications. Percutaneous microwave ablation is an effective, safe, and feasible method for cirrhosis patients with hypersplenism.

    This study aims to compare the clinical outcomes and costs between percutaneous transhepatic biliary stenting (PTBS) and surgical bypass. We randomly assigned 142 patients with unresectable malignant biliary obstruction between 2005 and 2010 to receive PTBS or surgical bypass as palliative treatment. PTBS was successfully performed in 70 patients who formed the PTBS group (failed in 7 patients). Sixty five patients underwent surgical bypass treatment. Additional gastrojejunostomy was performed in five patients. The effectiveness of biliary drainage, hospital stay, complications, cost, survival time and mortality were compared. Patients in PTBS group had shorter hospital stay and lower initial and overall expense than the surgical group (pPTBS group was significantly lower than surgical group (3/75 vs. 11/65, p=0.0342). Late complication in PTBS group did not differ significantly from surgical group (9/70 vs. 6/65, p=0.6823). The survival curves in the two groups showed no significant difference (p=0.1032). PTBD is a better palliative treatment than surgical bypass for unresectable malignant biliary obstruction for its high effectiveness of biliary drainage and acceptable expense and complication.

    Full Text Available Objective To describe the technique of computed tomography-guided percutaneous biopsy of pancreatic tumors with pneumodissection. Materials and Methods In the period from June 2011 to May 2012, seven computed tomography-guided percutaneous biopsies of pancreatic tumors utilizing pneumodissection were performed in the authors' institution. All the procedures were performed with an automatic biopsy gun and coaxial system with Tru-core needles. The biopsy specimens were histologically assessed. Results In all the cases the pancreatic mass could not be directly approached by computed tomography without passing through major organs and structures. The injection of air allowed the displacement of adjacent structures and creation of a safe coaxial needle pathway toward the lesion. Biopsy was successfully performed in all the cases, yielding appropriate specimens for pathological analysis. Conclusion Pneumodissection is a safe, inexpensive and technically easy approach to perform percutaneous biopsy in selected cases where direct access to the pancreatic tumor is not feasible.

    2002-01-01

    Purpose: Thrombin injection is becoming well established for the percutaneous management of iatrogenic pseudoaneurysms. All the published series to date use bovine thrombin,and there have been reports of adverse immunologic effects following its use. Our study aimed to assess the efficacy of human thrombin injection for pseudoaneurysm occlusion. Methods:Fourteen patients with iatrogenic pseudoaneurysms underwent a color Doppler ultrasound examination to assess their suitability for percutaneous human thrombin injection. Human thrombin 1000 IU was then injected into the pseudoaneurysm sac under sterile conditions and with ultrasound guidance. A further color Doppler ultrasound examination was performed 24 hr later to confirm occlusion. Results: All 14 pseudoaneurysms were successfully occluded by human thrombin injection. In two cases a second injection of thrombin was required,but there were no other complications, and all pseudoaneurysms remained occluded at 24 hr. Conclusion: Ultrasound-guided human thrombin injection is simple to perform, effective and safe. We recommend that human thrombin becomes the agent of choice for percutaneous injection into iatrogenic pseudoaneurysms

    To present our experience in ultrasound-guided percutaneous biopsy of lesions located in the digestive tract. We performed ultrasound-guided percutaneous biopsy in 14 patients (10 men and 4 women) ranging in age from 7 to 71 years (mean; 519 years). The lesions were located throughout the digestive tract, from the pyriform sinus to the sigmoid colon. The biopsy was carried out with a 5 MHz convex probe equipped with a device to direct the needle. An 18G automatic needle or a 20G Chiba needle was used to obtain specimens for histological study in every case, and additional samples were collected with a 22G needle for cytological examination in 13 of the patients. The ultrasound images corresponded to pseudokidney in 9 cases and extrinsic masses in 5. The diagnosis was obtained from the histological examination in every case (100%) and from cytology in 6 (44.4%), the latter results were less specific. The only complication corresponded to a case of bilioperitoneum. Ultrasound-guided percutaneous biopsy is a suitable technique for the histological diagnosis of those lesions of the digestive tract that are visible in ultrasound images, but that for some reason can not be examined by endoscopic biopsy.

    2000-01-01

    Herpes simplex virus encephalitis (HSE) is the most frequent viral encephalitis, as a rule with the starting point and centre within the temporal lobe. If untreated, HSE is usually fatal, thus diagnosis has to be established rapidly. Treatment with Acyclovir should begin as soon possible. As MRI is extremely sensitive in detecting the early inflammatory changes, it should be initially performed, especially as in the early stadium CT may be unspecific. We recommend the following examination protocol: coronar T1-weighted MR imaging before and after administration of gadopentetate dimeglumine, coronar FLAIR sequence and axial T2-weighted imaging. The diagnostic proof is to show the evidence of viral DNA by polymerase chain reaction (PCR) in cerebrospinal liquor. (orig.) [de

    To evaluate the indications, technique, results, and complications of image-guided percutaneous biopsy of the urinary bladder. This retrospective study included 15 patients (10 male, 5 female) who underwent image-guided percutaneous biopsy of the urinary bladder between January 1999 and December 2013. The medical records, imaging studies, procedural details, and long-term follow-up of each patient were reviewed in detail to assess the feasibility of percutaneous bladder biopsy. Ten patients had focal bladder masses and 5 patients had asymmetric or diffuse bladder wall thickening. Eleven patients had either negative or unsatisfactory cystoscopies prior to the biopsy. Percutaneous biopsies were performed under computed tomography guidance in 12 patients and ultrasound in 3 patients. All procedures were technically successful and there were no procedural complications. Malignancy was confirmed in 8 patients, among whom 6 had transitional cell carcinoma, 1 cervical cancer, and 1 prostate cancer metastasis. Seven patients had a benign diagnosis, including 3 that were later confirmed by pathology following surgery and 2 patients with a false-negative result. The overall sensitivity was 80% and accuracy was 87%. Image-guided percutaneous biopsy of the urinary bladder is a safe and technically feasible procedure with a high sensitivity and accuracy rate. Although image-guided bladder biopsy is an uncommon procedure, it should be considered in selected cases when more traditional methods of tissue sampling are either not possible or fail to identify abnormalities detected by cross-sectional imaging.

    While primary percutaneous coronary intervention (PCI) has significantly contributed to improve the mortality in patients with ST segment elevation myocardial infarction even in cardiogenic shock, primary PCI is a standard of care in most of Japanese institutions. Whereas there are high numbers of available facilities providing primary PCI in Japan, there are no clear guidelines focusing on procedural aspect of the standardized care. Whilst updated guidelines for the management of acute myocardial infarction were recently published by European Society of Cardiology, the following major changes are indicated; (1) radial access and drug-eluting stent over bare metal stent were recommended as Class I indication, and (2) complete revascularization before hospital discharge (either immediate or staged) is now considered as Class IIa recommendation. Although the primary PCI is consistently recommended in recent and previous guidelines, the device lag from Europe, the frequent usage of coronary imaging modalities in Japan, and the difference in available medical therapy or mechanical support may prevent direct application of European guidelines to Japanese population. The Task Force on Primary Percutaneous Coronary Intervention of the Japanese Association of Cardiovascular Intervention and Therapeutics (CVIT) has now proposed the expert consensus document for the management of acute myocardial infarction focusing on procedural aspect of primary PCI.

    The Republic of Croatia, with a gross domestic product per capita of US$11,554 in 2008, is an economically less-developed Western country. The goal of the present investigation was to prove that a well-organized primary percutaneous coronary intervention network in an economically less-developed country equalizes the prospects of all patients with acute ST-segment elevation myocardial infarction at a level comparable to that of more economically developed countries. We prospectively investigated 1,190 patients with acute ST-segment elevation myocardial infarction treated with primary PCI in 8 centers across Croatia (677 nontransferred and 513 transferred). The postprocedural Thrombolysis In Myocardial Infarction flow, in-hospital mortality, and incidence of major adverse cardiovascular events (ie, mortality, pectoral angina, restenosis, reinfarction, coronary artery bypass graft, and cerebrovascular accident rate) during 6 months of follow-up were compared between the nontransferred and transferred subgroups and in the subgroups of older patients, women, and those with cardiogenic shock. In all investigated patients, the average door-to-balloon time was 108 minutes, and the total ischemic time was 265 minutes. Postprocedural Thrombolysis In Myocardial Infarction 3 flow was established in 87.1% of the patients, and the in-hospital mortality rate was 4.4%. No statistically significant difference was found in the results of treatment between the transferred and nontransferred patients overall or in the subgroups of patients >75 years, women, and those with cardiogenic shock. In conclusion, the Croatian Primary Percutaneous Coronary Intervention Network has ensured treatment results of acute ST-segment elevation myocardial infarction comparable to those of randomized studies and registries of more economically developed countries.

    The results of CT/US-guided percutaneous drainage in 35 patients with pancreatic pseudocysts are reported. 27 patients recovered without surgery and no further treatment was required. 8 patients required a subsequent surgery due to recurrence. The role of CT/US-guided percutaneous drainage in pancreatic pseudocysts as well as an analysis of the technical aspects associated with a successful procedure are discussed. Although US may be used, we believe CT is safer and allows more precise localisation and guidance in the treatment of pseudocysts. (orig.).

    Percutaneous cecostomy or colostomy is a new interventional radiology procedure used for colonic decompression due to mechanical obstruction or pseudoobstruction. This paper describes our laboratory and initial clinical work with percutaneous colostomy. In our initial nine patient, it has served as a temporizing (five patients), definitive (three patients), or inadvertent maneuver (one patient). Methods of guidance were CT (three patients) and fluoroscopy (six patients). Catheters were placed both transperitoneally and retroperitoneally; laboratory work focused on these paths of introduction as well as catheter insertion and catheter type. The authors used catheters with retention devices preferentially, and these permit adherence of the colon to the abdominal wall. Both Seldinger and trocar techniques have been utilized. Leakage has resulted in minor abdominal pain; no patient has required operation due to percutaneous cecostomy. All procedures were successful and accomplished their goal

    Stenosis of the pancreatico-enteric anastomosis is one of the major complications of pancreaticoduodenectomy (PD). Endoscopic stent placement, has limited success rate as a nonsurgical treatment due to altered gastrointestinal anatomy. Percutaneous treatment is rarely attempted due to the technical difficulty in accessing the pancreatic duct. We reported a case of pancreaticojejunostomy stenosis after PD, in which a pancreatic stent was successfully placed using a rendezvous technique with a dual percutaneous approach.

    To examine the relationship between body mass index (BMI) and outcomes after percutaneous coronary intervention (PCI) in a multiethnic South East Asian population. Fifteen participating cardiology centres contributed to the Malaysian National Cardiovascular Disease Database-Percutaneous Coronary Intervention (NCVD-PCI) registry. 28 742 patients from the NCVD-PCI registry who had their first PCI between January 2007 and December 2014 were included. Those without their BMI recorded or BMI 70 kg/m 2 were excluded. In-hospital death, major adverse cardiovascular events (MACEs), vascular complications between different BMI groups were examined. Multivariable-adjusted HRs for 1-year mortality after PCI among the BMI groups were also calculated. The patients were divided into four groups; underweight (BMI PCI. Multivariable Cox proportional hazard regression analysis showed that compared with normal BMI group the underweight group had a non-significant difference (HR 1.02, p=0.952), while the overweight group had significantly lower risk of 1-year mortality (HR 0.71, p=0.005). The obese group also showed lower HR but this was non-significant (HR 0.78, p=0.056). Using Asian-specific BMI cut-off points, the overweight group in our study population was independently associated with lower risk of 1-year mortality after PCI compared with the normal BMI group. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    This study aims to offer experimental data and indirect evidences for the application of percutaneous rotational atherectomy to treat patent ductus arteriosus (PDA). Eleven dogs (6 male dogs and 5 female dogs; aged 14-20 months, with an average of 16.7±3.2 months; weight 20-25 kg, with an average of 22.7±2.5 kg) were enrolled in this study. The diameters of the left and right arteries ranged from 3.2 to 4.8 mm (average 3.9±0.6 mm) on percutaneous angiography. Percutaneous rotational atherectomy with proper rotablator (the size was 1-1.5 mm larger than the artery diameter) was performed in the arterial intima. After 4 weeks from percutaneous rotational atherectomy, arteriography was conducted to observe the changes in artery diameter. Then all dogs were sacrificed and the pathologic examination was conducted on the left and right axillary arteries. There were obvious changes with different degrees in 22 arteries, including 8 arteries with complete occlusion and 12 arteries with stenosis (≥2/3, 1/2, and 1/3 stenosis in 4, 4, and 4 arteries, respectively). The occlusion rate was 36.4% and the total effective rate was 90.9%. It was considered failure in other 2 arteries with atherectomy of arterial intima can promote the occlusion of arteries. This has provided a new choice for the treatment of PDA. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Unstable angina is an acute coronary syndrome without elevation of the ST segment. It is clinically important because of its threatening and crippling nature, due to the possibility that it could precede acute myocardial infarction. That is why it is determined that the patient suffering from this condition must be hospitalized in the Intensive Care Unit. There are various therapeutic strategies and several forms to approach the treatment of each patient, but in many cases it is necessary a percutaneous coronary intervention and this procedure is not carried out in this hospital. That is why it is necessary to establish a guideline for the treatment of this condition with the aim of optimizing the medications and making an adequate selection of the patients who require being transferred to a hospital with interventional cardiology services. A proposal for treatment protocol is presented in this work. It can function as a guideline for those who on daily basis treat patient with this condition at the Roberto Rodriguez Fernandez University Hospital in Morón city.

    Several treatment options exist for unicameral bone cysts (UBCs), including observation, steroid injection, bone marrow injection, and curettage and bone grafting. These are all associated with high recurrence rates, persistence, and occasional complications. Newer techniques have been described, most with variable success and only short follow-up reported. Because of these factors, a new minimally invasive percutaneous technique was developed for the treatment of UBCs in children. Twenty-eight children with UBCs who underwent percutaneous intramedullary decompression, curettage, and grafting with medical-grade calcium sulfate (MGCS) pellets by the senior author (J.P.D.) between April 2000 and April 2003 were analyzed as part of a pediatric musculoskeletal tumor registry at a large tertiary children's hospital. Four patients were lost to follow-up, and the remaining 24 patients had an average follow-up of 21.9 months (range 4-48 months). Twelve patients were followed for at least 24 months. Six of the 24 children had received previous treatment of their UBC, most often at an outside institution. Follow-up was performed through clinical evaluation and radiographic review. Postoperative radiographs at most recent follow-up showed complete healing, defined as more than 95% opacification, in 22 of 24 patients (91.7%). One patient (4.2%) demonstrated partial healing, defined as 80% to 95% opacification. One patient had less than 80% radiographic healing (4.2%). All 24 patients returned to full activities and were asymptomatic at most recent follow-up. The only complication noted was a superficial suture abscess that occurred in one patient; this resolved with local treatment measures. The new minimally invasive technique of percutaneous intramedullary decompression, curettage, and grafting with MGCS pellets demonstrates favorable results with low complication and recurrence rates compared with conventional techniques.

    To present our experience with a central, non-calyceal puncture protocol for percutaneous nephrolithotripsy (PCNL) in an attempt to challenge the opinion of worldwide adopted calyceal puncture as the less traumatic site of percutaneous entrance into the collecting system. During 2012, a total of 137 consecutive, unselected patients were subjected to PCNL in our department. Non-calyceal punctures were performed to all cases and followed by subsequent track dilations up to 30 Fr. Perioperative and postoperative data were prospectively collected and analyzed. Mean operative time (from skin puncture to nephrostomy tube placement) was 48 min. Patients with single, multiple and staghorn stones had primary stone-free rates of 89.2, 80.4 and 66.7 % after PCNL, respectively. The overall complication rate was 10.2 %, while bleeding complications were minimal. Only 4 patients (2.9 %) required blood transfusion. Five patients (3.6 %) had Clavien Grade IIIa complications requiring an intervention for their management and none Grade IV or V. Despite the absence of evidence that non-calyceal percutaneous tracts could be a risk factor for complications, the concept of calyceal puncture has been worldwide adopted by PCNL surgeons as the sole safe percutaneous entrance into the collective system. Based on our experience, other pathways than the worldwide recognized rule, calyceal puncture, are possible and probably not as dangerous as has been previously stated.

    Background: In amyotrophic lateral sclerosis (ALS) patients with respiratory impairment and/or advanced disease, performing even mild sedation - as is usually necessary for percutaneous endoscopic gastrostomy (PEG) placements - is fraught with risk. These patients are often referred to Interventional Radiology for alternative percutaneous gastrostomy tube placement options. Purpose: To report our experience with CT fluoroscopy-guided percutaneous gastrostomy with a novel loop gastropexy and peel-away sheath trocar technique in ALS patients as an alternative to endoscopic techniques. Material and Methods: A consecutive series of 31 amyotrophic lateral sclerosis patients in whom endoscopic gastrostomy was considered too dangerous or impossible to perform underwent CT-guided percutaneous gastropexy and gastrostomy and prospective follow-up. All procedures were performed with a 15 FR Freka Pexact gastrostomy kit, a 16-row CT scanner (Aquilion 16) and single shot CT fluoroscopy mode. Results: The procedure was performed successfully in 30 of 31 patients (20 men, 11 women; median age 60 years, range 38-80 years). In the remaining case the stomach was punctured under CT fluoroscopy and CO2 insufflation was initiated thereafter, leading to successful gastrostomy without prior gastropexy and without further adverse events during follow-up. Two patients reported unproblematic exchange of a balloon tube due to skin irritations with no further adverse events. One patient reported accidental displacement of an exchanged new balloon tube in domestic environment due to balloon leakage: A new balloon tube was easily re-inserted in a hospital the same day. No serious adverse events such as peritonitis, persistent local bleeding, systemic blood loss, or any local infection requiring surgical intervention were observed. Until August 11, 2011 follow-up resulted in 7473 cumulative gastrostomy-days from the date of first placement. Conclusion: Initial results suggest that the described

    Traditional surgical management of acute diverticulitis with abscess may require a one-, two-, or three-stage procedure. Because of recent interest in CT diagnosis of diverticulitis, and novel access routes for interventional drainage of deep pelvic abscesses, the authors investigated the potential for converting complex two- and three-stage surgical procedures to simpler, safer one-stage colon resections by percutaneous drainage of the associated abscess. Of 23 patients with acute perforated diverticulitis who were referred for catheter drainage under radiologic guidance, successful catheter drainage and subsequent single-stage colon resection were carried out in 15. In three patients catheter drainage was unsuccessful and a multistage procedure was required. In three patients only percutaneous drainage was performed and operative intervention was omitted entirely

    Full Text Available OBJECTIVE: Since the introduction of percutaneous nephrolithotomy (PCNL, many changes have been added regarding the entrance to pyelocalyceal system such as insertion of the needle pointed to an opaque stone as a guided landmark. We aim at comparing the outcomes of managing renal calculi with and without retrograde pyelography. MATERIALS AND METHODS: In a randomized clinical trial, 55 cases with opaque renal calculi candidates for PCNL with stone in one calyce, in the pelvis or both in one calyce and the pelvis simultaneously were included in a nine-month study. They were randomized into 2 groups, noncatheterized (n = 28 and catheterized (n = 27, called intervention and control groups, respectively. RESULTS: The 2 groups had similar distributions regarding gender, age, duration of operation, length of hospital stay, past history of any surgical procedures on kidney, and stone size. Outcome (residual stone based on aforementioned management was evaluated with plain X-ray on the morning following the operation. Postoperative hemoglobin decrease was significantly higher in controls than in the intervention group (p < 0.001 (with no clinical significance. No difference in outcome, postoperative fever, duration of surgery, duration of hospital stay and radiation exposure was observed between the 2 groups. CONCLUSION: Our findings showed no differences in major clinical outcomes between the 2 groups (with and without catheter insertion for retrograde pyelography.

    Full Text Available ABSTRACT Background and Purpose A tubeless PCNL can reduce postoperative pain, the need for analgesics, hospital stay, and postoperative urinary leakage. However, perioperative or delayed bleeding remains the primary postoperative concern. We demonstrate a simple and cost-effective method to develop a clear nephrostomy tract after completion of a tubeless PCNL. Materials and Methods Four consecutive patients with renal calculi >3cm underwent a tubeless PCNL. We used a 24 Fr nephroscope and a 24 Fr transurethral resectoscope. Intraoperative urologist-directed percutaneous renal access was performed under fluoroscopy. After calculi removal, active bleeders were identified via a clear Amplatz renal sheath. The sheath provided excellent visualization of the nephrostomy tract for the detection of bleeders and surrounding structures. Bleeders were electrocauterized using a roller barrel electrode. During extraction of the renal sheath, the surgeon can confirm hemostasis in the tract and apply intermittent suction. Results Bleeding primarily originated from the torn calyeceal mucosa and the parenchyma. Tract electrocauterization was successful. All patients had mild hematuria, which resolved within two days. The average hemoglobin decrease was 1.65g/dL (0.8-2.1 and no patients required a transfusion. No perioperative complications occurred. On postoperative day 2, the patients could ambulate without a Foley catheter. During three months of follow-up, delayed bleeding or percutaneous urine leakage did not occur. Conclusions Electrocauterization with a roller barrel electrode and a clear Amplatz renal sheath is an effective method to obtain hemostasis after completion of a PCNL. Our technique is cost-effective and readily adapted without the need for additional instruments.

    The chronic effects of ST-segment elevation myocardial infarction (STEMI) on the atrioventricular conduction (AVC) system have not been elucidated. This study aimed to evaluate the incidence, predictors, and outcomes of worsened AVC post-STEMI in patients treated with a primary percutaneous coronary intervention (PCI). The current analysis included patients from the HORIZONS-AMI trial who underwent primary PCI and had available ECGs. Patients with high-grade atrioventricular block or pacemaker implant at baseline were excluded. Analysis of ECGs excluding the acute hospitalization period indicated worsened AVC in 131 patients (worsened AVC group) and stable AVC in 2833 patients (stable AVC group). Patients with worsened AVC were older, had a higher frequency of hypertension, diabetes, renal insufficiency, previous coronary artery bypass grafting, and predominant left anterior descending culprit lesions. Predictors of worsened AVC included age, hypertension, and previous history of coronary artery disease. Worsened AVC was associated with an increased rate of all-cause death and major adverse cardiac events (death, myocardial infarction, ischemic target vessel revascularization, and stroke) as well as death or reinfarction at 3 years. On multivariable analysis, worsened AVC remained an independent predictor of all-cause death (hazard ratio: 2.005, confidence interval: 1.051-3.827, P=0.0348) and major adverse cardiac events (hazard ratio 1.542, confidence interval: 1.059-2.244, P=0.0238). Progression of AVC system disease in patients with STEMI treated with primary PCI is uncommon, occurs primarily in the setting of anterior myocardial infarction, and portends a high risk for death and major adverse cardiac events.

    Proximal humeral fractures are common lesions; there is no generally accepted strategy about the treatment for displaced and unstable two- to four-part fractures. We have nowadays many different surgical solutions, ranging from percutaneous pinning to shoulder arthroplasty. Percutaneous plating can be a good solution to treat some of these fractures using a minimally invasive technique and performing stable fixation that can allow early mobilization. Purpose of this paper is to evaluate the results of our first cases of percutaneous plating in proximal humeral fractures in order to assess the theoretical advantages and the incidence of possible complications. From June 2009 to February 2012, we treated 29 proximal humeral fractures with a percutaneous plating (NCB-PH plate) through an anterolateral deltoid split. For each patient, we evaluated the clinical outcome according to Constant score and the radiographic results, paying attention to fracture healing, loss of reduction, hardware complications, and head necrosis. The clinical evaluation gave a mean Constant score value of 79 points. Comparing each value to the unaffected shoulder, we could find these results: 7 excellent, 10 good, 8 fair, and 4 poor. No axillary nerve lesions were clinically detected. The radiographic evaluation showed a complete bone healing in all cases within the first 3 months. No head necrosis was detected, as well as screws loosening. In two cases, the X-ray at 2 months revealed a little loss of reduction in varus. Two patients had an anterior pain; in one of these two cases, the plate was removed. In our series, we had no cases of head necrosis, screws cutout, fracture collapse, hardware mobilization, and we think this could be the real advantage of the percutaneous technique compared to the open one, thanks to the reduced biological damage. We had some poor results, related more to patient's age than to other factors. The safety of the technique for the axillary nerve is

    Pediatric supracondylar humerus fractures are common injuries that are often treated surgically with closed reduction and percutaneous pinning. Although surgical-site infections are rare, postoperative antibiotics are frequently administered without evidence or guidelines for their use. With the increasing prevalence of antibiotic-resistant organisms and heightened focus on health care costs, appropriate and evidence-based use of antibiotics is needed. We hypothesized that postoperative antibiotic administration would not decrease the rate of surgical-site infection. A billing query identified 951 patients with operatively treated supracondylar humerus fractures at our institution over a 15-year period. Records were reviewed for demographic data, perioperative antibiotic use, and the presence of surgical-site infection. Exclusion criteria were open fractures, open reduction, pathologic fractures, metabolic bone disease, the presence of other injuries that required operative treatment, and follow-up <2 weeks after pin removal. χ and Fisher exact test were used to compare antibiotic use to the incidence of surgical-site infection. Six hundred eighteen patients met our inclusion criteria. Two hundred thirty-eight patients (38.5%) received postoperative antibiotics. Eleven surgical-site infections were identified for an overall rate of 1.8%. The use of postoperative antibiotics was not associated with a lower rate of surgical-site infection (P=0.883). Patients with a type III fracture (P<0.001), diminished preoperative vascular (P=0.001) and neurological status (P=0.019), and postoperative hospital admission (P<0.001) were significantly more likely to receive postoperative antibiotics. Administration of postoperative antibiotics after closed reduction and percutaneous pinning of pediatric supracondylar humerus fractures does not decrease the rate of surgical-site infection.

Methods: Between April 2001 and March 2003, 65 consecutive patients (36 men and 29 women; age range 33-88 years, mean 54 years) with obstructive jaundice underwent transluminal forceps biopsy or/and brush during percutaneous transhepatic cholangiography, percutaneous transhepatic cholangiography and drainage, or placement of stents. The technique was performed through an existing percutaneous transhepatic tract. Multiple specimens were obtained after passing the biopsy forceps or brush into a long 8-French sheath, and the specimens were fixed with formalin for pathologic or cytologic diagnosis. Statistical analysis was performed with the χ 2 test or Fisher exact probability, and P 2 =5.919, P=0.015). The cyctologic diagnosis was acquired in 43 of 58 patients with brush biopsy. Pathologic reports included cholangioadenocarcinoma (n=36), cholangiosquam-ocarcinoma (n=1), pancreatic adenocarcinoma (n=1), hepatocellular carcinoma (n=2), metastatic carcinoma (n=2), zoogloea aggregation (n=1), and negative results (n=15). The sensitivity rate of brush biopsy was 74.14%. Sensitivity of brush in the 45 patients with cholangiocarcinoma was higher than in the 11 patients with malignant tumors other than cholangiocarcinoma (82.22% vs 45.45%, χ 2 =4.563, P=0.033). Sensitivity of forceps biopsy in the 65 patients was higher than that of brush in the 58 patients (χ 2 =4.754, P=0.029). Conclusion: Percutaneous transhepatic cholangiobiopsy is a safe and minimal invasive procedure with no pain and low complication that is easy to perform with no addition trauma through a transhepatic biliary drainage tract. It is an effective, economic, accurate, and reliable new approach, which is safe and easy to perform in acquiring the pathologic diagnosis worthy to spread extensively. (authors)

    Supine percutaneous nephrolithotomy (PCNL) has been described in 1988 and several modifications followed since. Despite claimed benefits, supine PCNL is still neglected by the majority of urologists. Lack of experience and the fear of complications are possible explanations for the resistance to

    Percutaneous transhepatic cholangiography (P.T.C.) is a most valuable procedure in differentiation of obstructive jaundice, whether benign (chiefly stone) or malignant condition. Authors present the clinical and P.T.C. findings of 30 cases of obstructive jaundice which were experienced from December 1975 to May 1977, at Department of Radiology, Kyung Pook National University Hospital. The summarized results were as follows. 1. The incidence of malignancy beyond the age of 40 was high compared with stone, which revealed relatively equal age distribution. 2. The stone showed as concave cupping in all cases (11 cases), but the malignancy showed as nipple formation (10 cases) and irregular narrowings (9 cases). 3. The dilation of the intrahepatic bile duct appeared 10 cases on malignancy among 19 cases of malignancy (52.6%) and 4 caes on stone which were multiple intrahepatic or common hepatic duct stones. 4. The dilation of the justproximal bile duct was severe on malignancy compared with stone. 5. The mean bilirubin level was high on malignancy (12.8 mg-%) compared with stone (10.3 mg-%).

    Full Text Available Abstract Background Osteolytic metastases around the acetabulum are frequent in tumour patients, and may cause intense and drug-resistant pain of the hip. These lesions also cause structural weakening of the pelvis, limping, and poor quality of life. Percutaneous acetabuloplasty is a mini-invasive procedure for the management of metastatic lesions due to carcinoma of the acetabulum performed in patients who cannot tolerate major surgery, or in patients towards whom radiotherapy had already proved ineffective. Methods We report a retrospective study in 25 such patients (30 acetabuli who were evaluated before and after percutaneous acetabuloplasty, with regard to pain, mobility of the hip joint, use of analgesics, by means of evaluation forms: Visual Analog Scale, Harris Hip Score, Western Ontario and McMaster Universities Index of Osteoarthritis (WOMAC, Eastern Cooperative Oncology Group (ECOG. The results obtained were analysed using the χ2 Test and Fisher's exact test. Significance was sent at P Results Marked clinical improvement was observed in all patients during the first six post-operative months, with gradual a worsening thereafter from deterioration of their general condition. Complete pain relief was achieved in 15 of our 25 (59% of patients, and pain reduction was achieved in the remaining 10 (41% patients. The mean duration of pain relief was 7.3 months. Pain recurred in three patients (12% between 2 weeks to 3 months. No major complications occurred. There was transient local pain in most cases, and 2 cases of venous injection of cement without clinical consequences. Conclusion Percutaneous acetabuloplasty is effective in improving the quality of life of patients with osteolytic bone tumours, even though the improvement is observed during the first 6 months only. It can be an effective aid to chemo- and radiotherapy in the management of acetabular metastases.

  17. MR-guided percutaneous cryotherapy of liver metastases

    2001-01-01

    The prognosis for patients with liver metastases depends on the therapeutic options regarding the treatment of the primary tumor, co-existing extrahepatic metastases and the extent and treatment possibilities of the hepatic metastases themselves. Numerous curative or palliative oncological therapeutic concepts have been introduced in case of non-resectable liver metastases to prolong survival while maintaining a highest possible quality of life. Cryotherapy, which can be performed percutaneously and under magnetic resonance guidance, is one of these manifold therapeutic modalities, combining the inherent advantages of MRI with minimal invasiveness. Excellent visualization of the frozen liver tissue, precise tumor ablation, as well as an almost painless intervention due to the analgetic effect of the ice are implicating percutaneous cryotherapy as an attractive alternative to other ablation techniques. First clinical results are promising. However, meticulous and extensive long-term evaluation on a broad clinical scale is required. (orig.) [de

    Endoscopic biliary stenting is well known as an optimal method of management of malignant hilar obstruction, but sometimes the result is not satisfactory, with early stent failure. Percutaneous transhepatic biliary drainage (PTBD) has a distinct advantage over endoscopic retrograde cholangiopancreatoscopy in that with ultrasound guidance one or more appropriate segments for drainage can be chosen. We evaluated the effectiveness of percutaneous transhepatic stenting as a rescue of early failure of endoscopic stenting. Ten patients (4 men, 6 women; age range, 52-78 years; mean age, 69 years) with inoperable biliary obstruction (2 patients with gall bladder cancer and hilar invasion, and 8 patients with Klatskin tumor) and with early endoscopic stent failure were included in our study. All of the patients underwent PTBD and percutaneous transhepatic biliary stenting. Metallic stents were placed in all patients for internal drainage. Percutaneous rescue stenting was successful in all the patients technically and clinically. Mean time for the development of biliary obstruction was 13.5 days after endoscopic stenting. The mean patency of the rescue stenting was 122 days. The mean survival time for percutaneous transhepatic rescue stenting was 226.3 days. In early failure of endoscopic biliary stenting, percutaneous transhepatic recanalization can be a possible solution.

    Therapeutic armamentarium for symptomatic intervertebral disc herniation includes conservative therapy, epidural infiltrations (interlaminar or trans-foraminal), percutaneous therapeutic techniques and surgical options. Percutaneous, therapeutic techniques are imaging-guided, minimally invasive treatments for intervertebral disc herniation which can be performed as outpatient procedures. They can be classified in 4 main categories: mechanical, thermal, chemical decompression and biomaterials implantation. Strict sterility measures are a prerequisite and should include extensive local sterility and antibiotic prophylaxis. Indications include the presence of a symptomatic, small to medium sized contained intervertebral disc herniation non-responding to a 4–6 weeks course of conservative therapy. Contraindications include sequestration, infection, segmental instability (spondylolisthesis), uncorrected coagulopathy or a patient unwilling to provide informed consent. Decompression techniques are feasible and reproducible, efficient (75–94% success rate) and safe (>0.5% mean complications rate) therapies for the treatment of symptomatic intervertebral disc herniation. Percutaneous, imaging guided, intervertebral disc therapeutic techniques can be proposed either as an initial treatment or as an attractive alternative prior to surgery for the therapy of symptomatic herniation in both cervical and lumbar spine. This article will describe the mechanism of action for different therapeutic techniques applied to intervertebral discs of cervical and lumbar spine, summarize the data concerning safety and effectiveness of these treatments, and provide a rational approach for the therapy of symptomatic intervertebral disc herniation in cervical and lumbar spine.

    This study aims to compare the clinical outcomes and costs between endoscopic biliary stenting (EBS) and percutaneous transhepatic biliary stenting (PTBS). We randomly assigned 112 patients with unresectable malignant biliary obstruction 2006 and 2011 to receive EBS or PTBS with self-expandable metal stent (SEMS) as palliative treatment. PTBS was successfully performed in 55 patients who formed the PTBS group (failed in 2 patients). EBS was successfully performed in 52 patients who formed the EBS group (failed in 3 patients). The effectiveness of biliary drainage, hospital stay, complications, cost, survival time and mortality were compared. Patients in PTBS group had shorter hospital stay and lower initial and overall expense than the BBS group (P PTBS group was significantly lower than in EBS group (3/55 vs 11/52, P = 0.0343). Late complications in the EBS group did not differ significantly from PTBS group (7/55 vs 9/52, P = 0.6922). The survival curves in the two groups showed no significant difference (P = 0.5294). Conclusions: 3.

    A case of percutaneous pulmonary valve implantation following a failed homograft in the pulmonary position is reported. A 16-year-old boy developed infective endocarditis of his pulmonary homograft, which was implanted four years earlier during a Ross procedure for congenital aortic stenosis. Following successful medical therapy, the boy was symptomatic due to pulmonary stenosis and regurgitation. A 22 mm Melody valve (Medtronic, USA) was successfully implanted percutaneously. His symptoms resolved and he was discharged home one day after the procedure. Echocardiography at the six-month follow-up demonstrated a normally functioning pulmonary valve. Percutaneous pulmonary valve replacement may make the Ross procedure a more attractive option for patients with aortic stenosis, particularly in the pediatric population.

    To evaluate whether sono-guided percutaneous automated gun biopsy is also useful in pediatricpatients with renal diseases. In the prone position of twenty pediatric patients with renal parenchymal diseases, percutaneous biopsy was done through lateral aspect of the lower pole of left kidney with automated biopsy gun under the guidance of ultrasonography. The biopsy needle was either of 18 or 20 gauge. The obtained core of renal tissue was examined with light, immunofluorescent or electron microscope by the renal pathologist. In 18 among 20 patients, adequate renal tissue core sufficient to be pathologically diagnosed was obtained. The histologic findings were as follows : IG A nephropathy (n = 2), lupus nephritis (n =2), minimal change glomerulonephritis (n = 5), membranoproliferative glomerulonephritis (n = 3), mesangialproliferative glomeru-lonephritis (n = 1), diffuse proliferative glomerulonephritis (n = 3), focalglomerulo-sclerosis (n = 1), membranous glomerulopathy (n = 1). No significant complications occurred during or after the biopsy. Sono-guided percutaneous renal biopsy using automated biopsy gun is also useful todiagnose renal parenchymal diseases without significant complications in pediatric patients

    To assess the usefulness of percutaneous drainage of abscess in the treatment of emphysematous pyelonephritis. Ten cases of nine patients with emphysematous pyelonephritis were percutaneously drained. All were suffering from diabetes mellitus. The procedure was performed under fluoroscopic guidance in nine cases and US guidance in one case in which bilateral multiloculated abscesses were present in the perirenal space. The results were classified as cure, partial success, recurrence, or failure. The mean drainage period and complication were analyzed. Eight cases were cured, and there was one case success. In one case, who had diffuse renal parenchymal destruction without perirenal fluid collection, the treatment failed. The longest drainage period was 45 days, in a case of re-insertion due to incidental catheter removal; the mean was 23 days. Bacteremia in one case was cured with antibiotic therapy which lasted two days. In diabetic patients, percutaneous drainage of obscess is thought to be a safe and effective method for the treatment of emphysematous pyelonephritis, and is one that does not involve diffuse destruction of renal parenchyma

    While surgical tracheotomies are currently performed using state-of-the-art operative techniques, percutaneous dilatational tracheostomy (PDT) is in a rapidly evolving state with regard to its technology and the number of techniques available. This has resulted in a range of new complications that are difficult to quantify on a scientific basis, given the fact that more than half of the patients who are tracheotomized in intensive care units die from their underlying disease. The new Tracheotomy Endoscope (TED) is designed to help prevent serious complications in dilatational tracheotomies and facilitate their management. The endoscope has been specifically adapted to meet the require-ments of percutaneous dilatational tracheotomies. It is fully compatible with all current techniques of PDT. The method is easy to learn. The percutaneous dilatational tracheotomy with the Tracheotomy Endoscope is a seven-step procedure: Advantages of the Tracheotomy Endoscope: Injuries to the posterior tracheal wall ar impossible (tracheoesophageal fistulas, pneumothorax). Minor bleeding sites on the tracheal mucosa can be controlled with a specially curved suction-coagulation tube introudeced through the Tracheotomy Endoscope. In cases with heavy bleeding and a risk of aspiration, the rigid indwelling Tracheotomy Endoscope provides a secure route for reintubating the patient with a cuffed endotracheal tube. It also allows for rapid conversion to an open surgical procedure if necessary. All the parts are easy to clean and are autoclavable. This type of endoscopically guided PDT creates an optimal link between the specialties of intensive care medicine and otorhinolaryngology. The Tracheotomy Endoscope (TED) increases the standard of safety in PDT.

    Percutaneous gastrostomies or gastroenterostomies serve for temporary or permanent enteric feeding in patients with obstruction or functional derangement of the esophagus or hypopharynx. In addition, this radiological procedure may be indicated for small bowel decompression. The authors present their experience in 71 patients. Insufflation of air through a nasogastric tube or catheter is the preferred method for gastric distension. The inferior margin of the left lobe of the liver and the transverse colon are localized sonographically and fluoroscopically prior to puncture. Either Seldinger or Trocartechniques have proven effective in establishing access to the stomach. The feeding tube is advanced into the proximal jejunum to reduce the likelyhood of gastroesophageal reflux and possible aspiration. Complications were encountered in four patients and included catheter dislocation in three and respiratory distress in one patient.

    In dogs and 11 patients a new endoscopic method for arteries has been developed. The approach is transfemoral, and endoscopy is combined with angiography, percutaneous transluminal angioplasty (PTA), and local lysis. An ultrathin endoscope with a diameter of 2.4 mm is used, which also provides a working channel with a diameter of 0.4 mm. Guide wires, contrast media, and drugs for local lysis can be inserted through this channel. Under fluoroscopic control, the endoscope is placed in the region of interest, followed by a special method for decreasing blood flow. Endoscopy is documented by video or by a high-speed camera. No complications have occurred. In all patients, it was possible to demonstrate the results of dilatation, recanalization, or local lysis before and after the interventional procedure. (orig.) [de

    Aims: To determine the sensitivity and complications of percutaneous biopsy of pancreatic masses, and whether typical computed tomography (CT) features of adenocarcinoma can reliably predict this diagnosis. Materials and methods: A 5 year retrospective analysis of percutaneous core biopsies of pancreatic masses and their CT features was undertaken. Data were retrieved from surgical/pathology databases; medical records and CT reports and images. Results: Three hundred and three patients underwent 372 biopsies; 56 of 87 patients had repeat biopsies. Malignancy was diagnosed in 276 patients, with ductal adenocarcinoma in 259 (85%). Final sensitivity of percutaneous biopsy for diagnosing pancreatic neoplasms was 90%; for repeat biopsy it was 87%. Complications occurred in 17 (4.6%) patients, in three of whom the complications were major (1%): one abscess, one duodenal perforation, one large retroperitoneal bleed. CT features typical of ductal adenocarcinoma were: hypovascular pancreatic mass with bile and/or pancreatic duct dilatation. Atypical CT features were: isodense or hypervascular mass, calcification, non-dilated ducts, cystic change, and extensive lymphadenopathy. Defining typical CT features of adenocarcinoma as true-positives, CT had a sensitivity of 68%, specificity of 95%, positive predictive value (PPV) of 98%, and negative predictive value of 41% for diagnosing pancreatic adenocarcinoma. Conclusion: Final sensitivity of percutaneous biopsy for establishing the diagnosis was 90%. CT features typical of pancreatic adenocarcinoma had high specificity and PPV. On some occasions, especially in frail patients with co-morbidity, it might be reasonable to assume a diagnosis of pancreatic cancer if CT features are typical, and biopsy only if CT shows atypical features

    To evaluate the therapeutic value, safety, and long-term clinical outcomes of percutaneous lumbar facet synovial cyst (LFSC) rupture. Our study was institutional review board (IRB)-approved and Health Insurance Portability and Accountability Act (HIPAA)-compliant. The study group comprised 71 patients (44 women, mean age: 65 ± 17 years) who underwent CT- or fluoroscopy-guided percutaneous LFSC rupture. The technical success of LFSC rupture, the long-term clinical outcome, including repeat procedures or surgery, and imaging findings on MRI and CT were recorded. Seventy-nine LFSC ruptures were performed in 71 patients. CT guidance was used in 57 cases and fluoroscopy guidance in 22 cases. LFSC rupture was technically successful in 58 out of 79 cases (73 %). Mean injection volume for cyst rupture was 3.6 ± 2.2 mL and a combination of steroid and anesthetic was injected in all cases. Over a mean follow-up time of 44 months, 12 % of patients underwent repeat cyst rupture, and 46 % eventually underwent surgery, whereas the majority of patients (55 %) experienced symptomatic relief and did not undergo surgery. There was no significant association between a successful outcome and age, sex, level, or size of LFSC (p > 0.1). LFSCs with T2 hypointensity were more likely to require surgery (p = 0.02). There was one complication, a bacterial skin infection that completely resolved following antibiotic therapy. Percutaneous LFSC rupture is an effective and safe nonsurgical treatment option for LFSC. More than half of treated patients were able to avoid subsequent surgery. Therefore, percutaneous LFSC rupture should be considered before surgical intervention. (orig.)

  16. Percutaneous central venous catheters versus peripheral cannulae for delivery of parenteral nutrition in neonates.

    Ainsworth, S B; Clerihew, L; McGuire, W

    2007-07-18

    Parenteral nutrition for neonates may be delivered via a short peripheral cannula or a central venous catheter. The latter may either be inserted via the umbilicus or percutaneously. Because of the complications associated with umbilical venous catheter use, many neonatal units prefer to use percutaneously inserted catheters following the initial stabilisation period. The method of parenteral nutrition delivery may affect nutrient input and consequently growth and development. Although potentially more difficult to place, percutaneous central venous catheters may be more stable than peripheral cannulae, and need less frequent replacement. These delivery methods may also be associated with different risks of adverse events, including acquired systemic infection and extravasation injury. To determine the effect of infusion via a percutaneous central venous catheter versus a peripheral cannula on nutrient input, growth and development, and complications including systemic infection, or extravasation injuries in newborn infants who require parenteral nutrition. The standard search strategy of the Cochrane Neonatal Review Group was used. This included searches of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2007), MEDLINE (1966 - February 2007), EMBASE (1980 - February 2007), conference proceedings, and previous reviews. Randomised controlled trials that compared the effect of delivering parenteral nutrition via a percutaneous central venous catheter versus a peripheral cannulae in neonates. Data were extracted the data using the standard methods of the Cochrane Neonatal Review Group, with separate evaluation of trial quality and data extraction by each author, and synthesis of data using relative risk, risk difference and mean difference. Four trials eligible for inclusion were found. These trials recruited a total of 368 infants and reported a number of different outcomes. One study showed that the use of a percutaneous

    This paper reports on a device for CT-targeted percutaneous punctures. After extensive phantom studies, punctures of vertebral disk space (diskography/nucleotomy) and orbit retrobulbar anesthesia/biopsy were performed in 15 patients. The new device is easy to mount on the CT scanner and does not require additional devices affixed to the patient. Its design and construction permit exact calculation of needle angle and depth, even when the gantry is tilted. Percutaneous biopsies can be performed in approximately 40 minutes. The device is accurate within ±0.5 mm, thereby allowing puncture of even small lesions deep in the orbital cone. Retrobulbar anesthesia can be performed safely in patients with a long myopic bulbus; in nucleotomy, instant control of the instrument's position within the disk space is possible

    AIM: CT-guided percutaneous cordotomy is a useful procedure for treating unilateral cancer pain, however, bilateral cordotomy can be required on some occasions. We evaluated the effectiveness and complications of bilateral cordotomy. MATERIALS AND METHODS: Two hundred and thirty-four patients who suffered from unilateral cancer pain underwent CT-guided percutaneous cordotomy. The procedure was repeated in 22 patients, and nine patients had bilateral cordotomy. Effectiveness and complications were recorded after each procedure. RESULTS: Of nine patents (three women and six men) having bilateral percutaneous cordotomy in our study, four patients had mirror pain after the first procedure. In the remaining five patients the contralateral pain was due to new pain sites. The pain scores before and after the first procedure were 9.3 (range 7-10) and 1.2 (range 0-3), respectively. After the first procedure complete or satisfactory pain relief was achieved in all patients. The duration between the two procedures ranged from 7-243 days (mean 59.8 days). The pain scores before and after the second procedure were 8.4 (range 5-10) and 1.6 (range 0-4), respectively. After the second procedure complete or satisfactory pain relief was reported in all patients. There were no complications in four patients. One patient developed transient motor deficit after the first procedure. Other complications (nausea/vomiting, headache, ipsilateral neck pain, postcordotomy dysesthesia) were mild and transient. CONCLUSION: CT-guided percutaneous cordotomy is a useful procedure for the treatment of severe unilateral cancer pain syndromes. The procedure can be repeated on the other side at least 1 week later. These results show that the success on the second side appears to be similar to the first side with low complication rate for both procedures.

    Objective. The purpose of this study is to determine the risk of CNS and/or peritoneal infection in children with ventriculoperitoneal shunts in whom a percutaneous gastrostomy tube is placed. Materials and methods. We placed 205 gastrostomy or gastrojejunostomy tubes from January of 1991 to December 1996. Twenty-three patients (10 boys, 13 girls) had ventriculoperitoneal shunts at the time of placement. All shunts were placed at least 1 month prior to placement of the gastrostomy tube. The patients ranged in age from 8 months to 16 years with a mean age of 6 years, 9 months. Patient weight ranged from 2 kg to 60 kg. All 23 children required long-term nutritional support due to severe neurologic impairment. No prophylactic antibiotics were given prior to the procedure. Of the patients, 21/23 had a 14-F Sacks-Vine gastrostomy tube with a fixed terminal retention device inserted, using percutaneous fluoroscopic antegrade technique. Two of the 23 patients had a Ross 14-F Flexi-flo gastrostomy tube which required a retrograde technique due to a small caliber esophagus in these children. Results. All 23 children had technically successful placements of percutaneous gastrostomy (7) or gastrojejunostomy (16) tubes. Of the children, 21/23 (91 %) had no complications from the procedure. Two of 23 (9 %) patients demonstrated signs of peritonitis after placement of their gastrostomy tubes and subsequently had shunt infections. In both, children CSF culture grew gram-positive cocci. The antegrade technique was used in both children who developed peritonitis. Conclusion. Our study indicates children with ventriculoperitoneal shunts who undergo percutaneous gastrostomy are at greater risk for infection and subsequent shunt malfunction. Therefore, we recommend prophylactic antibiotic therapy to cover for skin and oral flora. (orig.) With 1 fig., 7 refs.

    ObjectiveTo describe a new interventional technique to remove foreign bodies (FBs) embedded in soft tissues around vital vessels.MethodsUnder fluoroscopic guidance and using local anesthesia, percutaneous removal of FBs was performed using forceps in nine patients. All patients suffered from a metallic soft tissue FB located in close proximity to important vessels and one also had a small traumatic pseudoaneurysm adjacent to the FB. Prior to removal of the FB, the position of the nearest vessel was identified using a guide wire or catheter placed into the vessel. Balloon catheter was also simultaneously used to temporarily stop the blood flow of the nearest artery during the FB removal in three of the nine patients.ResultsAll of the nine FBs with 0–2 mm interval to the nearest vessel were successfully removed in the nine patients without any serious complications. The removed FBs measured 3–12 mm in length and 1–3 mm in width. The total fluoroscopic time of retrieval of each FB was 5–9 min (mean, 6.4 min). The volume of intraoperative bleeding ranged from 5 to 12 ml (mean, 7.5 ml). The length of hospital stay for each patient ranged from 4 to 8 days (mean, 5.5 days).ConclusionVascular intervention-aided percutaneous FB removal is minimally invasive and an effective method for removal of FBs around vital vessels.

    The aim of this study was to report the outcomes of PCNL in patients in whom the Short and Thin Pediatric Set (ST PEDISET) had been used. Data from 21 patients (11 boys and 10 girls) who underwent PCNL for renal stones using the ST PEDISET between April 2013 and February 2015 were analyzed retrospectively. The patients were evaluated by plane radiography and USG after surgery. In total 21 children (11 boys and 10 girls) with a median age of 13months (range 5months to 4years) who underwent PCNL were included in the study. The median stone burden was 16mm (range 10-36mm). The success rate was 85.7%. Sixteen patients (76.2%) were stone free and two patients (9.5%) had clinically insignificant residual fragments (CIRF). The median length of hospital stay was 4days (range 2-9days). The data of this study clearly show that the ST PEDISET is safe, effective and ergonomic for percutaneous nephrolithotomy in preschool-age children. This study indicates the need for randomized trials on larger cohorts to confirm these findings, and thus improve the surgical procedure. Copyright © 2016 Elsevier Inc. All rights reserved.

    Purpose: To report on the nephron-sparing, percutaneous ablation of a large renal cell carcinoma by combined superselective embolization and percutaneous radiofrequency ablation. Materials and Methods: A 5 cm renal cell carcinoma of a 43-year-old drug abusing male with serologically proven HIV, hepatitis B and C infection, who refused surgery, was superselectively embolized using microspheres (size: 500 - 700 {mu}m) and a platinum coil under local anesthesia. Percutaneous radiofrequency ablation using a 7F LeVeen probe (size of expanded probe tip: 40 mm) and a 200 Watt generator was performed one day after transcatheter embolization under general anesthesia. Results: The combined treatment resulted in complete destruction of the tumor without relevant damage of the surrounding healthy renal tissue. The patient was discharged 24 hours after RF ablation. No complications like urinary leaks or fistulas were observed and follow up CT one day and 4 weeks after the radiofrequency intervention revealed no signs of residual tumor growth. Conclusion: The combined transcatheter embolization and percutaneous radiofrequency ablation of renal cell carcinoma has proved technically feasible, effective, and safe in this patient. It may be offered as an alternative treatment to partial or radical nephrectomy under certain circumstances.

    In recent years ultrasound guided percutaneous tracheostomy (USPCT) has become a routine practice in critical care units. Its safety and superiority over conventional percutaneous tracheostomy and bronchoscopic guided PCT is proven to be non-inferior in elective cases. However its role in emergency percutaneous tracheostomy has never been studied, since percutaneous tracheostomy itself remains an enigma in accessing emergency airway. There is no report of use of ultrasound guided percutaneous tracheostomy in emergency setting so far in the literature. We report our early experience with USPCT in emergency setting. Sixteen adult patients who required access to an emergency surgical airway after failure to accomplish emergency oro-tracheal intubation were the study population. Their airway was accessed by USPCT. Recorded data included clinical and demographic data including time taken to perform the procedure and complications. Short term and long term follow ups for a period of 2 years were done for the survivors. Twelve male and four female patients underwent the procedure and the average time of the procedure was 3.6 min with no failures nor conversions to surgical tracheostomy and no complications. The average oxygen saturation was 86% and average Glasgow coma scale was 8.4. This time period included the oxygen insufflation time. 10 patients were decannulated while six patients died due to the pathology of the disease itself. There were no complications in either short term or long term follow up. USPCT has a definitive role in emergency both in trauma and non-trauma setting. It is safe, feasible and faster in experienced hands. Use of USPCT in emergency setting has further narrowed the list of contraindications of percutaneous tracheostomy.

    Atherosclerotic peripheral vascular disease (PVD) of the lower extremities deprives a person of the ability to exercise to their satisfaction, later of the ability to perform the activities of their daily life, and finally of their legs themselves. Peripheral vascular disease has long been managed by the vascular surgeon utilizing endarterectomy and peripheral arterial bypass. Patient acceptance of nonsurgical, percutaneous procedures such as percutaneous transluminal balloon angioplasty (PTA) is high. Increased utilization of these procedures has led to improved techniques and adjuncts to therapy, as well as more critical review of long-term results. This article will review the evaluation and nonoperative management of PVD, with an emphasis on the newer modalities of management presently being investigated

    We are developing a self-contained cardiac pacemaker with a small, cylindrical shape (~3 × 20 mm) that permits it to be implanted percutaneously into a fetus to treat complete heart block and consequent hydrops fetalis, which is otherwise fatal. The device uses off-the-shelf components including a rechargeable lithium cell and a highly efficient relaxation oscillator encapsulated in epoxy and glass. A corkscrew electrode made from activated iridium can be screwed into the myocardium, followed by release of the pacemaker and a short, flexible lead entirely within the chest of the fetus to avoid dislodgement from fetal movement. The feasibility of implanting the device percutaneously under ultrasonic imaging guidance was demonstrated in acute adult rabbit experiments.

    Since the publication of the 2009 SCAI Expert Consensus Document on Length of Stay Following percutaneous coronary intervention (PCI), advances in vascular access techniques, stent technology, and antiplatelet pharmacology have facilitated changes in discharge patterns following PCI. Additional clinical studies have demonstrated the safety of early and same day discharge in selected patients with uncomplicated PCI, while reimbursement policies have discouraged unnecessary hospitalization. This consensus update: (1) clarifies clinical and reimbursement definitions of discharge strategies, (2) reviews the technological advances and literature supporting reduced hospitalization duration and risk assessment, and (3) describes changes to the consensus recommendations on length of stay following PCI (Supporting Information Table S1). These recommendations are intended to support reasonable clinical decision making regarding postprocedure length of stay for a broad spectrum of patients undergoing PCI, rather than prescribing a specific period of observation for individual patients. © 2018 Wiley Periodicals, Inc.

    Full Text Available Background: In recent years, it has been proposed that the primary mechanism for the development of food allergies is percutaneous sensitization. Since 2010, in Japan, the number of immediate-type wheat allergy due to hydrolyzed wheat protein has dramatically increased among those who have been using soap containing hydrolyzed wheat. This incidence supports the hypothesis that food allergens arise through percutaneous sensitization. Clinical Summary: A 25-year-old man (case 1 and an 18-year-old girl (case 2 with atopic dermatitis visited our Department because of food allergy and hand eczema. After starting their work with fish, severe itchy eczema appeared on their hands. They subsequently started to experience oral allergic symptoms, intraoral itchiness and dyspnea after eating fish. Specific IgE antibodies were detected for many fishes, and skin prick tests showed positive reactions for a variety of fishes in both cases. Furthermore, the fluorescence intensities of specific IgE antibodies against parvalbumin from various types of fish in microarray immunoassay analysis showed positive reactions. We diagnosed them as contact urticaria caused by percutaneous sensitization to parvalbumin through job-related physical contact with fish. Conclusion: The patients' histories and findings indicate the possibility of percutaneous sensitization through occupational exposure to parvalbumin, leading to food allergy.

    To evaluate the safety and efficacy of ultrasound-guided percutaneous core needle biopsy of splenic lesions. This retrospective study included 30 patients who underwent percutaneous core needle biopsy of their splenic lesions using 18- or 20-gauge needles between January 2001 and July 2016 in a single tertiary care center. The characteristics of the splenic lesions were determined by reviewing the ultrasound and computed tomography examinations. Acquisition rate and diagnostic accuracy were calculated, using pathologic results of the splenectomy specimen, clinical course and/or imaging follow-up as a reference standard. Post-procedure complications were identified from electronic medical records, laboratory findings and computed tomography images. Seventy-three specimens were obtained from the 30 patients and splenectomy was performed in 2 patients. Twenty-nine of the 30 patients had focal splenic lesions, while the remaining patient had homogeneous splenomegaly. Acquisition rate and diagnostic accuracy were 80.0% (24/30) and 76.7% (23/30), respectively. Perisplenic hemorrhage without hemodynamic instability developed in one patient. Ultrasound-guided percutaneous core needle biopsy of splenic lesions is a safe method for achieving a histopathologic diagnosis and can be considered as an alternative to splenectomy in patients with a high risk of splenectomy-related complications.

    Percutaneous treatment of renal artery stenosis (RAS) is an accepted procedure and numerous reports have been published. However, experience with its use in RAS in the transplanted kidney in children is scarce. Since 1994 we have diagnosed RAS in seven children with the use of Doppler ultrasonography (US), confirming it with percutaneous angiography (PAG). In six of the seven patients percutaneous transluminal angioplasty (PTA) was performed. In one patient a metallic stent was placed due to the extension of the arterial lesion, and a second stent was placed in another child when a re-stenosis was diagnosed 1 month after the PTA. All patients presented with hypertension (de novo or 30% increase over previous values). After ruling out acute rejection, calcineurin inhibitor toxicity, and urinary obstruction, US was performed and, when an increase in arterial flux velocity was registered, PAG was also performed. Six children showed an increase in serum creatinine (Cr) and proteinuria. Blood pressure decreased after the procedure and Cr returned to previous levels in all children. One of the grafts was lost due to chronic transplant rejection 7 years later. The other children have a functioning kidney. Although this is a small group of patients, the consistently good results and the lack of reported experience prompted us to communicate our preliminary observation.

    Percutaneous transhepatic biliary drainage is a safe, effective and palliative means of treatment in biliary obstruction, especially in cases with malignant obstruction which are inoperable. 175 cases of transhepatic biliary drainage were performed on 119 patients with biliary obstruction from January 1985 to June 1989 at Kyung-pook National University Hospital. The causes of obstructive jaundice were 110 malignant diseases and 9 benign diseases. The most common indication for drainage was palliative intervention of obstruction secondary to malignant tumor in 89 cases. 86 cases of external drainage were performed including 3 cases of left duct approach, 29 cases of external-internal drainage and 60 cases of endoprosthesis. In external and external-internal drainages, immediate major complications (11.9%) occurred, including not restricted to, but sepsis, bile peritonitis and hemobilia. Delayed major complications (42.9%) were mainly catheter related. The delayed major complication of endoprosthesis resulted from obstruction of the internal stent. The mean time period to reobstruction of the internal stent was about 12 weeks. To improve management status, regular follow-up is required, as is education of both patients and their families as to when immediate clinical attention is mandated. Close communication amongst the varying medical specialities involved will be necessary to provide optional treatment for each patient.

In external and external-internal drainages, immediate major complications (11.9%) occurred, including not restricted to, but sepsis, bile peritonitis and hemobilia. Delayed major complications (42.9%) were mainly catheter related. The delayed major complication of endoprosthesis resulted from obstruction of the internal stent. The mean time period to reobstruction of the internal stent was about 12 weeks. To improve management status, regular follow-up is required, as is education of both patients and their families as to when immediate clinical attention is mandated. Close communication amongst the varying medical specialities involved will be necessary to provide optional treatment for each patient

    Gaining access into non-dilated renal collecting systems for percutaneous nephrolithotripsy, particularly in patients with prohibitive body habitus and/or scoliosis, is often challenging using conventional techniques. To evaluate the feasibility of cone-beam CT for percutaneous nephrostomy placement for subsequent percutaneous nephrolithotripsy in children and adolescents. A retrospective review of percutaneous nephrostomy revealed use of cone-beam CT and 3-D guidance in 12 percutaneous nephrostomy procedures for 9 patients between 2006 and 2015. All cone-beam CT-guided percutaneous nephrostomies were for pre-lithotripsy access and all 12 were placed in non-dilated collecting systems. Technical success was 100%. There were no complications. Cone-beam CT with 3-D guidance is a technically feasible technique for percutaneous nephrostomy in children and adolescents, specifically for nephrolithotripsy access in non-dilated collecting systems.

    Background: In recent years, it has been proposed that the primary mechanism for the development of food allergies is percutaneous sensitization. Since 2010, in Japan, the number of immediate-type wheat allergy due to hydrolyzed wheat protein has dramatically increased among those who have been using soap containing hydrolyzed wheat. This incidence supports the hypothesis that food allergens arise through percutaneous sensitization. Clinical Summary: A 25-year-old man (case 1) and an 18-year-...

    PurposeTo evaluate the feasibility, risks, and techniques of percutaneous removal of permanent TrapEase and Simon Nitinol IVC filters.Materials and MethodsBetween August 2011 and August 2015, 12 patients (5 women, 7 men; age range, 26–75 years) underwent an attempt at percutaneous removal of permanent TrapEase (10) and Simon Nitinol (2) IVC filters due to a history of IVC filter complications or need for lifelong anticoagulation due to the filter. Medical records were reviewed for filter dwell time, presence of iliocaval deep venous thrombosis, procedural technique, and complications.ResultsFilter dwell times ranged from 7 days to 15 years (mean 5.1 years). Successful removal of permanent IVC filters was possible in 11 of 12 patients (91.6 %). In 1 patient, a chronically thrombosed IVC filter could not be removed despite laser sheath assistance, but was successfully recanalized with the PowerWire RF guidewire. In the failed retrieval attempt, a stent was placed through the chronically thrombosed IVC filter with restoration of in-line flow. One major complication of large venous groin hematoma was encountered.ConclusionsIn carefully selected patients, percutaneous removal of permanent IVC filters can be performed safely despite prolonged filter dwell times. Extraction of chronically embedded permanent IVC filters may be facilitated by jugular and femoral approaches, often with laser sheath assistance. Chronic filter thrombosis and caval scarring may increase the risk of retrieval failure.

    This study investigated the relationships between Type D personality, depression, and social support among ethnic Chinese coronary artery disease (CAD) patients undergoing percutaneous coronary interventions. Type D personality is associated with CAD, and may increase patients' depression and mortality rate. However, very few studies have explored the relationships between depression and social support among ethnic Chinese Type D CAD patients. A longitudinal, repeated-measures design was used; 105 Taiwanese CAD patients undergoing a percutaneous coronary intervention were recruited between January and December 2015. A demographic questionnaire, Type D Scale, ENRICHD Social Support Inventory, and Patient Health Questionnaire-9 were completed by 102 participants (mean age = 64.42, SD = 13.67 years) at hospitalization, and at the second week and third month after discharge. Data were analyzed using t tests and a generalized estimating equation. Results indicated that 46.7% of participants who had Type D personality had lower social support and higher depression than did the remaining (non-Type D) participants. At two weeks after discharge, the improvement in social support was higher among Type D patients than non-Type D participants; the same was true for depression at two weeks and three months after discharge each. Type D Taiwanese CAD patients showed lower perceived social support and higher depression during hospitalization than did non-Type D participants. Furthermore, the more social support patients received at home, the lower was their depression. Health-care providers should provide continuous mental health care, conduct early screening of mental health issues, and ensure that patients receive sufficient social support to reduce depression.

    The authors report their experience in the study of 8 patients showing sympoms of thyroid hyperfunction (Plummer's adenoma) and treated with US-guided percutaneous ethanol injection. The treatment consisted in injecting sterile ethanol in varying amounts (2 to 5 ml) according to nodule size, using a fine needle under US guidance. The patients underwent 3 to 6 injections, according to biochemical (T3-T4-TSH) and scintigraphic findings. Follow-up ay 12 months showed regression of clinical symptoms, a trend of hormone levels toward normalization and recovery of previously suppressed parenchymal function. No significant complications were observed, except for a transient thyrotoxic crisis in the patient bearing the largest nodule. The treatment of Plummer's adenoma by means of percutaneous ethanol injection under us guidance appears to provide specific clinical and technical advantages over other conventional treatments

    Full Text Available Office-based percutaneous revision of a testicular prosthesis has never been reported. A patient received a testicular prosthesis but was dissatisfied with the firmness of the implant. In an office setting, the prosthesis was inflated with additional fluid via a percutaneous approach. Evaluated outcomes included patient satisfaction, prosthesis size, recovery time, and cost savings. The patient was satisfied, with no infection, leak, or complication after more than 1 year of follow-up, at significantly less cost than revision surgery. Percutaneous adjustment of testicular prosthesis fill-volume can be safe, inexpensive, and result in good patient satisfaction.

This unwanted complication occurs due to adhesion of bacteria and subsequent biofilm formation. To solve this problem, we have developed a novel antibiotic nanodelivery system based on self-decomposable silica nanoparticles. In this study, silica-gentamycin (SG nanoparticles were successfully fabricated using an innovative one-pot solution. The nanoparticles were incorporated within a gelatin matrix and cross-linked on microarc-oxidized titanium. To characterize the SG nanoparticles, their particle size, zeta potential, surface morphology, in vitro drug release, and decomposition process were sequentially evaluated. The antibacterial properties against the gram-positive Staphylococcus aureus, including bacterial viability, antibacterial rate, and bacteria morphology, were analyzed using SG-loaded titanium specimens. Any possible influence of released gentamycin on the viability of human fibroblasts, which are the main component of soft tissues, was investigated. SG nanoparticles from the

    Full Text Available Background: Direct percutaneous endoscopic jejunostomy (DPEJ is a useful method to provide enteral nutrition to individuals when gastric feeding is not possible or contraindicated. The aim of this study was to analyze the efficacy and safety of DPEJ tube placement with the Gauderer-Ponsky technique by the pull method, using single-balloon enteroscopy (SBE without fluoroscopy. Methods: This is a retrospective analysis of patients undergoing SBE for DPEJ placement in a referral hospital between January 2010 and March 2016. Technical success, clinical success and procedure related complications were recorded. Results: Twenty-three patients were included (17 males, median age 71 years, range 37-93 years. The most frequent indications for DPEJ were gastroesophageal cancer (n = 10 and neurological disease (n = 8. Eighty-seven percent of the patients had a contraindication to percutaneous endoscopic gastrostomy (PEG and PEG was unsuccessful in the remaining patients. The technical success rate was 83% (19/23, transillumination was not possible in three patients and an accidental exteriorization of the bumper resulting in a jejunal perforation occurred in one patient. The clinical success was 100% (19/19. The median follow-up was five months (range 1-35 months. Apart from the case of jejunal perforation and the two cases of accidental exteriorization, there were no other complications during follow-up. The 6-month survival was 65.8% and the 1-year survival was 49.3%. Conclusion: DPEJ can be carried out successfully via SBE without fluoroscopy with a low rate of significant adverse events. Although, leaving the overtube in place during the bumper pulling can be useful for distal jejunal loops, it can be safely removed in proximal loops to minimize complications.

Thirty-six patients were randomized and assigned into US-guided percutaneous electrolysis (n=17 group or exercise (n=19 group. Patients were asked to perform an eccentric exercise program of the rotator cuff muscles twice every day for 4 weeks. Participants assigned to US-guided percutaneous electrolysis group also received the application of galvanic current through acupuncture needle on each session once a week (total 4 sessions. Shoulder pain (NPRS and disability (DASH were assessed at baseline, after 2 sessions, and 1 week after the last session. Results. The ANOVA revealed significant Group∗Time interactions for shoulder pain and disability (all, P<0.01: individuals receiving US-guided percutaneous electrolysis combined with the eccentric exercises experienced greater improvement than those receiving eccentric exercise alone. Conclusions. US-guided percutaneous electrolysis combined with eccentric exercises resulted in small better outcomes at short term compared to when only eccentric exercises were applied in subacromial pain syndrome. The effect was statistically and clinically significant for shoulder pain but below minimal clinical difference for function. Future studies should investigate the long-term effects and potential placebo effect of this intervention.

    Intra-abdominal abscess is a common complication of Crohn disease in children. Prior studies, primarily in adults, have shown that percutaneous abscess drainage is a safe and effective treatment for this condition; however, the data regarding this procedure and indications in pediatric patients is limited. Our aim was to determine the success rate of percutaneous abscess drainage for abscesses related to Crohn disease in pediatric patients with a focus on treatment endpoints that are relevant in the era of biological medical therapy. We retrospectively reviewed 25 cases of patients ages ≤20 years with Crohn disease who underwent percutaneous abscess drainage. Technical success was defined as catheter placement within the abscess with reduction in abscess size on post-treatment imaging. Clinical success was defined as (1) no surgery within 1 year of drainage or (2) surgical resection following drainage with no residual abscess at surgery or on preoperative imaging. Multiple clinical parameters were analyzed for association with treatment success or failure. All cases were classified as technical successes. Nineteen cases were classified as clinical successes (76%), including 7 patients (28%) who required no surgery within 1 year of percutaneous drainage and 12 patients (48%) who had elective bowel resection within 1 year. There was a statistically significant association between resumption of immunosuppressive therapy within 8 weeks of drainage and both clinical success (P < 0.01) and avoidance of surgery after 1 year (P < 0.01). Percutaneous abscess drainage is an effective treatment for Crohn disease-related abscesses in pediatric patients. Early resumption of immunosuppressive therapy is statistically associated with both clinical success and avoidance of bowel resection, suggesting a role for percutaneous drainage in facilitating prompt initiation of medical therapy and preventing surgical bowel resection.

    Objectives: To report our experience with percutaneous cool-tip radiofrequency ablation of osteoid osteomas and to evaluate clinical outcome. Methods and material: Forty-one patients with clinically and radiologically suspected osteoid osteoma were seen over a 48-month period (27 males and 14 females with a mean age of 18.7 years; range 5-43 years). Thirty-eight patients were treated by computed tomography (CT)-guided percutaneous radiofrequency ablation. The procedure was performed under regional or general anaesthesia. After location of the nidus, a 14G-bone biopsy needle is introduced into the nidus. Sampling is performed with a 17G-bone biopsy needle using a coaxial technique. The radiofrequency needle with a 10 mm active tip (cool-tip) is inserted through the biopsy needle and is connected to the radiofrequency generator for 6-8 min. Results: Primary success was obtained in 37 patients (97%) with a 100% secondary success rate. All patients are currently pain-free. No major complications occurred. Patients could resume unrestricted normal activity within 24 h. Conclusions: Percutaneous radiofrequency ablation of osteoid osteomas is an efficient and safe method that can be considered the procedure of choice for most cases.

    Elbow tendinopathy is the most common cause of elbow pain affecting active populations. Surgical excision is reserved for patients with refractory symptoms. Percutaneous ultrasonic tenotomy performed under local anesthesia also removes degenerated tissue and therefore provides an alternative treatment option to surgical excision. This investigation prospectively documented the safety and 1-year efficacy of ultrasonic percutaneous tenotomy performed by a single operator. Nineteen patients, aged 38 to 67 years, in whom >6 months of conservative management for medial (7) or lateral (12) elbow tendinopathy had failed were prospectively studied. All patients were treated with percutaneous ultrasonic tenotomy of the elbow by a single operator. Visual analog scale (VAS) for pain, the 11-item version of the Disabilities of the Arm, Shoulder, and Hand (Quick DASH) index, and the Mayo Elbow Performance Score (MEPS) were assessed by an independent observer before treatment and at 6 weeks, 3 months, 6 months, and 12 months after treatment. No procedural complications occurred. Total treatment time was elbow tendinopathy up to 1 year after the procedure. Copyright © 2015 Journal of Shoulder and Elbow Surgery Board of Trustees.

    A long-term evaluation of a new percutaneously placed bioprosthetic, bicuspid venous valve (BVV) consisting of a square stent and small intestinal submucosa (SIS) covering was performed in 12 sheep. Of 26 BVVs placed into the jugular veins, 25 exhibited good valve function on immediate venography and 22 on venograms obtained before the sheep were killed. Gross and histologic examination results demonstrated incorporation of remodeled and endothelialized SIS BVVs into the vein wall. Slight to moderate leaflet thickening was found mostly at their bases. Percutaneously placed SIS BVV is a promising one-way, competent valve that resists venous back-pressure while allowing forward flow.

    Percutaneous mitral valve (MV) repair has been performed in over 20,000 patients worldwide. As clinical experience in this technique grows indications for its use are being defined. Mitral regurgitation (MR) encompasses a complex heterogeneous group and its treatment is governed by determining a clear understanding of the underlying aetiology. Surgical MV repair remains the gold standard therapy for severe MR. However in select groups of high-risk surgical patients, a percutaneous approach to MV repair is establishing its role. This review gives an overview of the published data in percutaneous MV repair and its impact on the contemporary management of MR. Published by the BMJ Publishing Group Limited.

    To compare the outcomes in patients who have been treated with flexible ureterorenoscopy (f-URS) and percutaneous nephrolithotomy (PNL) in managing stone-bearing caliceal diverticula. Between April 2007 and October 2013, we performed a retrospective analysis of 54 evaluable patients (28 women and 26 men) with symptomatic stone-bearing caliceal diverticula, who underwent PNL (n = 29) or F-URS (n = 25) in four referral hospitals in Turkey. The groups were compared with respect to demographics, stone location/size, success rate, stone-free status, symptom-free status, complication rates, and hospital stay. The average stone burden preoperatively was significantly larger in patients who were treated with PNL, with the average size for f-URS being 154 ± 77 mm(2) and that for PNL being 211 ± 97 mm(2) (p = 0.023). Symptom-free rates, success rates, stone-free rates and clinically insignificant residual fragments were similar between the groups (p = 0.880 vs. p = 0.537 vs. p = 0.539, and p = 0.877, respectively). There was no statistical difference between the groups for minor complications (p = 0.521) but no major complication (Clavien III-V) occured in the f-URS group; although there were three major complications (10.3 %) (Clavien III) in the PNL group (p PNL group (p PNL. The f-URS procedure is advantageous with respect to a shorter hospital stay and absence of major complications. Therefore, it should be emphasized that the location of the stone and diverticula is an important factor for the selection of the procedure.

    The presence of stones in the common bile duct (CBD) may cause complications such as obstructing jaundice or ascending cholangitis, and the stones should be removed. To assess the efficacy of percutaneous elimination of CBD stones from the gallbladder through the papilla. During a 4 year period, six patients (five men and one woman, mean age 71.5 years) who had CBD stones and an existing gallbladder drain underwent percutaneous stone push into the duodenum after balloon dilatation of the papilla, with a diameter equal to that of the largest stone. Access into the CBD was from the gallbladder, using an already existing percutaneous gallbladder drain (cholecystostomy tube). Each patient had one to three CBD stones measuring 7-14 mm. Successful CBD stone elimination into the duodenum was achieved in five of the six patients. The single failure occurred in a patient with choledochal diverticulum, who was operated successfully. There were no major or minor complications during or after the procedures. Trans-cholecystic CBD stone elimination is a safe and feasible percutaneous technique that utilizes existing tracts, thus obviating the need to create new percutaneous access. This procedure can replace endoscopic or surgical CBD exploration.

    To evaluate the safety of transgression of the bowel during intraperitoneal percutaneous catheter placement in an animal model. Eight 8-F straight catheters were percutaneously inserted into the small and large bowel of eight rabbits. In four animals, the catheters were left in place until autopsy, whereas in the remaining four, the catheters were withdrawn five days after insertion. Autopsy was performed in all animals ten days after catheter placement, and gross and microscopic examination was carried out. Transgressing the bowel during intraperitoneal percutaneous catheter placement did not contribute to any clinically significant complications. At autopsy, there was no bowel leakage, peritonitis, or abscess, although peritoneal adhesions were found around the catheter tract. Although further study is warranted, our study with an animal model indicated that transgression of the intestine during percutaneous placement of an intraabdominal catheter did not produce significant complications

    After the introduction of tubeless percutaneous nephrolithotomy (PNL), many studies conducted in adult patients have confirmed its efficacy and safety. There are limited studies reporting that tubeless PNL can be safely applied in children, however. Furthermore, there are no reports that evaluate the use of totally tubeless PNL in children. The present study evaluates the results of totally tubeless PNL in preschool children. The data of children seen in our clinic who were considered suitable for totally tubeless PNL were analyzed. Of 16 children, 8 patients underwent totally tubeless PNL (group 1) and 8 standard PNL (group 2). The two groups of patients were compared with regard to length of hospitalization, analgesic requirements, transfusion rates, hemoglobin (Hb) decrease, and immediate, early, and late complications. The mean ages of the patients were 56.6 months (9-84 mos) and 56.0 months (5-84 mos), and the mean follow-up was 21.5 months (3-44 mos) and 43.4 months (36-54 mos) in groups 1 and 2, respectively. Both groups were similar with regard to age, stone size, Hb change, and complications. Although operation duration, hospitalization period, and analgesic requirement were less in the totally tubeless PNL group, these differences were not statistically significant. The latest application of PNL, totally tubeless PNL, is also a safe and effective procedure in very small children if they are selected properly and if the surgeon has sufficient experience with the procedure. More studies with a higher number of participants are needed, however, to confirm that totally tubeless PNL increases the comfort of pediatric patients, decreases their hospitalization period, and is more economical.

    Objective: To study the effect of trans-radial approach (TRA) on achievement of a door-to-balloon time (DBT) of A/sup 2/ 90 minutes in primary PCI percutaneous coronary intervention (PPCI) for ST-elevation myocardial infarction (STEMI). Study Design: Case series. Place and Duration of Study: Armed Forces Institute of Cardiology - National Institute of Heart Diseases (AFIC -NIHD), Rawalpindi, from October 2011 to August 2012. Methodology: Systems goal for door-to-balloon time (DBT - time elapsed between first medical contact and restoration of flow in the infarct related artery (IRA)) was set at < 90 minutes. Procedural success was defined as restoration of TIMI 3 flow in the IRA with less than 30% residual stenosis and discharge from hospital. Non-infarct related arteries were not treated. Bleeding episodes were defined by TIMI definitions. Results: For vascular access for PPCI in a total of 207 patients, TRA was 91.3% (n = 189), transfemoral approach (TFA) 6.3% (n = 13) and brachial 2.4% (n = 5). Males represented 90.3% of cases and 7% were females. Mean age was 55 A +- 10.86 years. Procedural success rate was 97.1%. Mean DBT was 54.1 minutes. DBT was less A/sup 2/ 60 and 90 minutes in 75% and 94.2% of patients respectively. DBT A/sup 2/ 89.50 minutes was achieved in 90% of patients. The difference in DBT between the different access groups was not markedly different between the three groups. There were 6 (2.9%) in-hospital deaths and no major bleeds. Conclusion: TRA for PPCI poses no hindrance to achieving a DBT of < 90 minutes in PPCI for STEMI. Furthermore, the in-hospital mortality rates are acceptable and within rational limits. (author)

    To evaluate the clinical outcome of patients with acute vocal fold paralysis treated with bovine collagen via percutaneous injection laryngoplasty under simple topical anesthesia. Retrospective case series. The charts of 38 consecutive patients with acute unilateral vocal fold paralysis who underwent percutaneous injection laryngoplasty under simple topical anesthesia were reviewed. Symptoms and laryngeal function were assessed pre- and postinjection using the Glottal Function Index (GFI), GRBAS Dysphonia Scale, Functional Outcome Swallowing Scale (FOSS), and maximum phonation time (MPT). Mean GFI, GRBAS, FOSS, and MPT improved from 13.71 to 7.68, 7.24 to 3.95, 3.70 to 2.20, and 12.87 to 16.45, respectively (P dysphagia and aspiration, injection was successful in restoring oral alimentation in only three patients, with the four failures occurring in patients with multiple cranial neuropathies. Percutaneous injection laryngoplasty is a viable option for immediate rehabilitation of acute vocal fold paralysis, and can be performed in the inpatient setting. With dysphagia and aspiration secondary to multiple cranial nerve palsies, medialization of the paralyzed cord alone may be insufficient to restore safe oral alimentation.

    Full Text Available Since the first report of percutaneous retrieval of intravascular foreign body in 1964, it has been accepted as a favorite approach for intravascular foreign body removal. Various instruments such as snares, biopsy forceps, dormia basket or tip deflecting wires are available for this approach. Herein, we report percutaneous retrieval of a dislodged guide-wire by dormia basket. The Patient was a 98-year-old female who was admitted in the Intensive care unit due to confusional state. The physian incharge left the guide-wire in her subclavian vein during central venous catheter insertion. He realized his fault immediately, so he started anti-coagulation therapy and requested surgical consult. Because of the patient’s high risk of surgery, the surgeon referred the patient to cardiologist for non-invasive guide wire removal. The guide wire was apprpached through femoral vein by a dormia basket (4/6 F and it was removed without any difficulties or complications. Utilization of baskets for intravascular foreign body removal is frequently reported and has been successful with low complication rates; In addition, the low cost of the device makes it less of a burden to the patient and the hospital.

    PurposeTo evaluate the safety and efficacy of US-guided percutaneous microwave (MW) ablation in the treatment of renal angiomyolipoma (AML).Materials and MethodsFrom January 2011 to April 2014, seven patients (5 females and 2 males; mean age 51.4) with 11 renal AMLs (9 sporadic type and 2 tuberous sclerosis associated) with a mean size of 3.4 ± 0.7 cm (range 2.4–4.9 cm) were treated with high-powered, gas-cooled percutaneous MW ablation under US guidance. Tumoral diameter, volume, and CT/MR enhancement were measured on pre-treatment, immediate post-ablation, and delayed post-ablation imaging. Clinical symptoms and creatinine were assessed on follow-up visits.ResultsAll ablations were technically successful and no major complications were encountered. Mean ablation parameters were ablation power of 65 W (range 60–70 W), using 456 mL of hydrodissection fluid per patient, over 4.7 min (range 3–8 min). Immediate post-ablation imaging demonstrated mean tumor diameter and volume decreases of 1.8 % (3.4–3.3 cm) and 1.7 % (27.5–26.3 cm{sup 3}), respectively. Delayed imaging follow-up obtained at a mean interval of 23.1 months (median 17.6; range 9–47) demonstrated mean tumor diameter and volume decreases of 29 % (3.4–2.4 cm) and 47 % (27.5–12.1 cm{sup 3}), respectively. Tumoral enhancement decreased on immediate post-procedure and delayed imaging by CT/MR parameters, indicating decreased tumor vascularity. No patients required additional intervention and no patients experienced spontaneous bleeding post-ablation.ConclusionOur early experience with high-powered, gas-cooled percutaneous MW ablation demonstrates it to be a safe and effective modality to devascularize and decrease the size of renal AMLs.

    There are two main enteral feeding strategies—namely nasogastric (NG) tube feeding and percutaneous gastrostomy—used to improve the nutritional status of patients with head and neck cancer (HNC). But up till now there has been no consistent evidence about which method of enteral feeding is the optimal method for this patient group. To compare the effectiveness of percutaneous gastrostomy and NGT feeding in patients with HNC, relevant literature was identified through Medline, Embase, Pubmed, Cochrane, Wiley and manual searches. We included randomized controlled trials (RCTs) and non-experimental studies comparing percutaneous gastrostomy—including percutaneous endoscopic gastrostomy (PEG) and percutaneous fluoroscopic gastrostomy (PFG)—with NG for HNC patients. Data extraction recorded characteristics of intervention, type of study and factors that contributed to the methodological quality of the individual studies. Data were then compared with respect to nutritional status, duration of feeding, complications, radiotherapy delays, disease-free survival and overall survival. Methodological quality of RCTs and non-experimental studies were assessed with separate standard grading scales. It became apparent from our studies that both feeding strategies have advantages and disadvantages. (author)

    Objective: To analyse our clinical experience with CT guided percutaneous renal cysts puncture and ethanol therapy. Methods: Five hundred and ten renal cysts in 445 patients were undergone CT guided percutaneous renal cysts puncture and ethanol therapy. Among the 445 cases, 385 cases had solitary renal cyst, 53 multiple renal cysts, and 7 polycystic kidneys. The renal cysts varied in size from 1.9 to 13.5 cm in diameter. The amount of aspirated fluid varied from 3 to 780 ml. A 18-21 gauge aspiration needles were used for all patients. A 25.0% cyst volume replacement with 99.7% ethanol was approved to be appropriate. Results: 427 renal cysts in 396 patients were followed up by computed tomographic (CT) or ultrasound for less than 3 months to more than one year duration. The curative effective rate and disappearance rate of the renal cystic cavity in solitary renal cysts were 97% and 82%, respectively. In multiple renal cysts, the corresponding values were 95% and 79%. In polycystic kidneys, the curative rate was 67%. The complications such as local abdominal pain (28 cases) and hematuria (four cases) were observed in this series. There were no fatal complications. Conclusions: CT guided percutaneous renal cyst puncture and ethanol therapy is an useful procedure for the treatment of solitary renal cysts and multiple renal cysts

    Indications for colostomy in colorectal diseases are obstruction of the large bowel, such as in cancer, diverticular disease in the acute phase, post-radiotherapy enteritis, complex perirectal fistulas, anorectal trauma and severe anal incontinence. Some critically ill patients cannot tolerate an exploratory laparotomy, and laparoscopic assisted colostomy also requires general anesthesia. To evaluate the feasibility, safety and efficacy of performing colostomy assisted by colonoscopy and percutaneous colopexy. Five pigs underwent endoscopic assisted colostomy with percutaneous colopexy. Animals were evaluated in post-operative days 1, 2, 5 and 7 for feeding acceptance and colostomy characteristics. On day 7 full colonoscopy was performed on animals followed by exploratory laparotomy. Average procedure time was 27 minutes (21-54 min). Postoperative mobility and feeding of animals were immediate after anesthesia recovery. Position of the colostomy, edges color, appearance of periostomal area, as well as its function was satisfactory in four animals. Retraction of colostomy was present in one pig. The colonoscopy and laparotomy control on the seventh day were considered as normal. A bladder perforation that was successfully repaired through the colostomy incision occurred in one pig. The main limitation of this study is its experimental nature. Endoscopic assisted colostomy with percutaneous colopexy proves to be a safe and effective method with low morbidity for performing colostomy in experimental animals, with possible clinical application in humans.

    IntroductionGastrostomy tube placement for patients requiring long-term nutritional support may be performed using different techniques including endoscopic, surgical, and percutaneous radiologically guided methods. Radiologically inserted gastrostomy (RIG), typically performed when percutaneous endoscopic gastrostomy is not possible, requires proper gastric distension that is achieved by insufflating air through a nasogastric tube. We describe a simple technique to prevent air escape from the stomach during gastrostomy tube placement. To the best of our knowledge, this technique has not yet been described in the literature.Materials and MethodsFour patients with unsuccessful percutaneous endoscopic gastrostomy were referred for fluoroscopic-guided gastrostomy. One patient had a pyriform sinus tumor and three had an ischemic stroke causing dysphagia. Gastric distention was not achieved in the patients due to air escaping into the bowel during the standard RIG procedure. A modified approach using a balloon catheter inflated in the pylorus to avoid air passing into the duodenum permitted successful RIG.ResultsThe modified RIG procedure was successfully carried out in all cases without complications.DiscussionInadequate air distension of the stomach is an unusual event that causes a failure of gastrostomy tube placement and an increased risk of both major and minor complications. The use of a balloon catheter inflated in the first part of the duodenum prevents the air passage into the bowel allowing the correct positioning of the gastrostomy.

    To compare survival outcomes of adults with out-of-hospital cardiac arrest (OHCA) of medical aetiology directly transported to a percutaneous-coronary-intervention capable (PCI-capable) hospital (direct transport) with patients transferred to a PCI-capable hospital via another hospital without PCI services available (indirect transport) by emergency medical services (EMS). This retrospective cohort study used the St John Ambulance Western Australia OHCA Database and medical chart review. We included OHCA patients (≥18 years) admitted to any one of five PCI-capable hospitals in Perth between January 2012 and December 2015. Survival to hospital discharge (STHD) and survival up to 12-months after OHCA were compared between the direct and indirect transport groups using multivariable logistic and Cox-proportional hazards regression, respectively, while adjusting for so-called "Utstein variables" and other potential confounders. Of the 509 included patients, 404 (79.4%) were directly transported to a PCI-capable hospital and 105 (20.6%) transferred via another hospital to a PCI-capable hospital; 274/509 (53.8%) patients STHD and 253/509 (49.7%) survived to 12-months after OHCA. Direct transport patients were twice as likely to STHD (adjusted odds ratio 1.97, 95% confidence interval [CI] 1.13-3.43) than those transferred via another hospital. Indirect transport was also associated with a possible increased risk of death, up to 12-months, compared to direct transport (adjusted hazard ratio 1.36, 95% CI 1.00-1.84). Direct transport to a PCI-capable hospital for post-resuscitation care is associated with a survival advantage for adults with OHCA of medical aetiology. This has implications for EMS transport protocols for patients with OHCA. Copyright © 2018 Elsevier B.V. All rights reserved.

    2017-01-01

    Percutaneous dilatational tracheostomy (PDT) is a commonly performed procedure in critically sick patients. It can be safely performed bedside by intensivists. This has resulted in decline in the use of surgical tracheostomy in intensive care unit (ICU) except in few selected cases. Most common indication of tracheostomy in ICU is need for prolonged ventilation. About 10% of patients requiring at least 3 days of mechanical ventilator support get tracheostomised during ICU stay. The ideal timing of PDT remains undecided at present. Contraindications and complications become fewer with increase in experience. Various methods of performing PDT have been discovered in last two decades. Preoperative work up, patient selection and post tracheostomy care form key components of a successful PDT. Bronchoscopy and ultrasound have been found to be useful procedural adjuncts, especially in presence of unfavorable anatomy. This article gives a brief overview about the use of PDT in ICU.

    Whether outcomes differ for women and men after percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) remains controversial. To compare 1-year outcomes after primary PCI in women and men with STEMI, matched for age and diabetes. Consecutive women with STEMI of0.05 for all). After exclusion of patients with shock (10.7%) and out-of-hospital cardiac arrest (6.6%), death rates were even more similar (11.3% vs 11.8%; P=0.10). Female sex was not independently associated with death (odds ratio 1.01, 95% confidence interval 0.55-1.87; P=0.97). In our consecutive unselected patient population, women had similar 1-year outcomes to men matched for age and diabetes, after contemporary primary PCI for STEMI, despite having a higher risk profile at baseline.

    Purpose: To determine the effectiveness of percutaneous transhepatic removal of bile duct stones when the procedure of endoscopic therapy fails for reasons of anatomical anomalies or is rejected by the patient. Methods: Between April 2001 and May 2010, 261 patients (138 male patients and 123 female patients; age range, 14-92 years; mean age, 64.6 years) with bile duct stones (common bile duct [CBD] stones = 248 patients and hepatolithiasis = 13 patients) were included in the study. Percutaneous transhepatic cholangiography was performed, and stones were identified. Percutaneous transhepatic balloon dilation of the papilla of Vater was performed. Then stones were pushed out into the duodenum with a Fogarty balloon catheter. If the stone diameter was larger than 15 mm, then basket lithotripsy was performed before balloon dilation. Results: Overall success rate was 95.7%. The procedure was successful in 97.5% of patients with CBD stones and in 61.5% of patients with hepatolithiasis. A total of 18 major complications (6.8%), including cholangitis (n = 7), subcapsular biloma (n = 4), subcapsular hematoma (n = 1), subcapsular abscess (n = 1), bile peritonitis (n = 1), duodenal perforation (n = 1), CBD perforation (n = 1), gastroduodenal artery pseudoaneurysm (n = 1), and right hepatic artery transection (n = 1), were observed after the procedure. There was no mortality. Conclusion: Our experience suggests that percutaneous transhepatic stone expulsion into the duodenum through the papilla is an effective and safe approach in the nonoperative management of the bile duct stones. It is a feasible alternative to surgery when endoscopic extraction fails or is rejected by the patient.

    The natural history and therapeutic interventions for secondary prevention after a cerebrovascular event in patients with patent foramen ovale (PFO) are not yet established. This study aims to assess the safety and efficacy of percutaneous PFO closure in a population of patients with ischemic cerebrovascular disease of unknown etiology. This prospective observational study included patients with a history of cryptogenic transient ischemic attack (TIA) or stroke who underwent percutaneous PFO closure. The effectiveness of the device for the secondary prevention of TIA or stroke was assessed by comparing observed events in the sample with expected events for this clinical setting. The sample included 193 cases of percutaneous PFO closure (age 46.4 ± 13.1 years, 62.2% female) with a mean follow-up of 4.3 ± 2.2 years, corresponding to a total exposure to ischemic events of 542 patient-years. The high-risk characteristics of the PFO were assessed prior to device implantation. There were seven primary endpoint events during follow-up (1.3 per 100 patient-years), corresponding to a relative risk reduction of 68.2% in recurrent TIA or stroke compared to medical therapy alone. The procedure was associated with a low rate of device- or intervention-related complications (1.5%). In this long-term registry, percutaneous PFO closure was shown to be a safe and effective therapy for the secondary prevention of cryptogenic stroke or TIA.

    To assess the efficacy and safety of ultrasound guided percutaneous cholecystostomy (PC) in the treatment of acute cholecystitis in a well-defined high risk patients under general anesthesia. The data of 27 consecutive patients who underwent percutaneous transhepatic cholecystostomy for the management of acute cholecystitis from January 1999 to June 2003 was retrospectively evaluated. All of the patients had both clinical and sonographic signs of acute cholecystitis and had comorbid diseases. Ultrasound revealed gallbladder stones in 25 patients and acalculous cholecystitis in two patients. Cholecystostomy catheters were removed 14-32 d (mean 23 d) after the procedure in cases where complete regression of all symptoms was achieved. There were statistically significant reductions in leukocytosis, (13.7 x 10(3)+/-1.3 x 10(3) microg/L vs 13 x 10(3)+/-1 x 10(3) microg/L, P extraction was performed successfully with endoscopic retrograde cholangio-pancreatography (ERCP) in three patients. After cholecystostomy, 5 (18%) patients underwent delayed cholecystectomy without any complications. Three out of 22 patients were admitted with recurrent acute cholecystitis during the follow-up and recovered with medical treatment. Catheter dislodgement occurred in three patients spontaneously, and two of them were managed by reinsertion of the catheter. As an alternative to surgery, percutaneous cholecystostomy seems to be a safe method in critically ill patients with acute cholecystitis and can be performed with low mortality and morbidity. Delayed cholecystectomy and ERCP, if needed, can be performed after the acute period has been resolved by percutaneous cholecystostomy.

    Purpose: To determine the effectiveness of percutaneous transhepatic removal of bile duct stones when the procedure of endoscopic therapy fails for reasons of anatomical anomalies or is rejected by the patient. Methods: Between April 2001 and May 2010, 261 patients (138 male patients and 123 female patients; age range, 14–92 years; mean age, 64.6 years) with bile duct stones (common bile duct [CBD] stones = 248 patients and hepatolithiasis = 13 patients) were included in the study. Percutaneous transhepatic cholangiography was performed, and stones were identified. Percutaneous transhepatic balloon dilation of the papilla of Vater was performed. Then stones were pushed out into the duodenum with a Fogarty balloon catheter. If the stone diameter was larger than 15 mm, then basket lithotripsy was performed before balloon dilation. Results: Overall success rate was 95.7%. The procedure was successful in 97.5% of patients with CBD stones and in 61.5% of patients with hepatolithiasis. A total of 18 major complications (6.8%), including cholangitis (n = 7), subcapsular biloma (n = 4), subcapsular hematoma (n = 1), subcapsular abscess (n = 1), bile peritonitis (n = 1), duodenal perforation (n = 1), CBD perforation (n = 1), gastroduodenal artery pseudoaneurysm (n = 1), and right hepatic artery transection (n = 1), were observed after the procedure. There was no mortality. Conclusion: Our experience suggests that percutaneous transhepatic stone expulsion into the duodenum through the papilla is an effective and safe approach in the nonoperative management of the bile duct stones. It is a feasible alternative to surgery when endoscopic extraction fails or is rejected by the patient.

    Choledocholithiasis is defined as presence of at least one gallstone in the bile duct. Those bile duct stones (BDS) usually are extracted by ERCP. In case the bile duct is not accessible endoscopically (e.g. after major abdominal surgery), PTCD has to be performed. Extraction of the stones via PTCD has several risks as are hemorrhage, pancreatitis and injuries of the liver tissue. We here report about our experience with a significant modification of this technique by use of a 13-french hemostasis introducer as a sheath to track the transhepatic access to the bile ducts in order to reduce time and risk. Three patients were treated by use of the reported modification. In all cases, the stones were successfully removable without complications. We demonstrate that the use of a hemostasis introducer for percutaneous extraction of common bile duct stones seems to be promising in terms of shortening hospital stay and increasing patient safety.

    This study aimed to compare the clinical outcomes of patients with advanced hilar cholangiocarcinoma (CC) who underwent photodynamic therapy (PDT) with either percutaneous transhepatic cholangioscopy (PTCS) or endoscopic retrograde cholangiopancreatography (ERCP). PDT has been proposed as a promising therapy for treatment of unresectable hilar CC that is resistant to conventional standard treatment. However, few studies have compared the delivery methods of PDT in unresectable hilar CC patients. Thirty-seven adult patients with advanced hilar CC were included in this study. Twenty-four patients treated with PTCS-directed PDT and 13 patients treated with ERCP-directed PDT were analyzed retrospectively. The PTCS- and ERCP-directed PDT groups were comparable with respect to age, gender, health status, pretreatment bilirubin levels, Bismuth type, and hilar CC stage. The length of hospital stay differed significantly (p hilar CC. Lower pre-PDT bilirubin levels were associated with longer survival in all patients.

    Full Text Available Abstract Background Tension pneumoperitoneum as a complication of iatrogenic bowel perforation during endoscopy is a dramatic condition in which intraperitoneal air under pressure causes hemodynamic and ventilatory compromise. Like tension pneumothorax, urgent intervention is required. Immediate surgical decompression though is not always possible due to the limitations of the preclinical management and sometimes to capacity constraints of medical staff and equipment in the clinic. Methods This is a retrospective analysis of cases of pneumoperitoneum and tension pneumoperitoneum due to iatrogenic bowel perforation. All patients admitted to our surgical department between January 2005 and October 2010 were included. Tension pneumoperitoneum was diagnosed in those patients presenting signs of hemodynamic and ventilatory compromise in addition to abdominal distension. Results Between January 2005 and October 2010 eleven patients with iatrogenic bowel perforation were admitted to our surgical department. The mean time between perforation and admission was 36 ± 14 hrs (range 30 min - 130 hrs, between ER admission and begin of the operation 3 hrs and 15 min ± 47 min (range 60 min - 9 hrs. Three out of eleven patients had clinical signs of tension pneumoperitoneum. In those patients emergency percutaneous needle decompression was performed with a 16G venous catheter. This improved significantly the patients' condition (stabilization of vital signs, reducing jugular vein congestion, bridging the time to the start of the operation. Conclusions Hemodynamical and respiratory compromise in addition to abdominal distension shortly after endoscopy are strongly suggestive of tension pneumoperitoneum due to iatrogenic bowel perforation. This is a rare but life threatening condition and it can be managed in a preclinical and clinical setting with emergency percutaneous needle decompression like tension pneumothorax. Emergency percutaneous decompression is no

    Objective: The treatment of vertebral split fractures remains controversial, consisting of either corset or internal fixation. The aim of this study was to evaluate the technical feasibility of CT- and fluoroscopy-guided percutaneous vertebroplasty in the treatment of vertebral split fractures. Materials and methods: Institutional review board approval and informed consent were obtained for this study. Sixty-two consecutive adult patients who had post-traumatic vertebral split fractures (A2 according to the AO classification) without neurological symptoms were prospectively treated by percutaneous vertebroplasty. All these procedures were performed by an interventional radiologist under computed tomography (CT) and fluoroscopy guidance by using only local anaesthesia. Postoperative outcome was assessed using the visual analogue scale (VAS) and Oswestry disability index (ODI) scores. Results: Vertebroplasty was performed on thoracic and lumbar vertebrae, creating a cement bridge between the displaced fragment and the rest of the vertebral body. Seven discal cement leakages (11%) were observed, without occurrence of adjacent vertebral compression fractures. The mean VAS measurements ± standard deviation (SD) significantly decreased from 7.9 ± 1.5 preoperatively to 3.3 ± 2.1 at 1 day, 2.2 ± 2.0 at 1 month, and 1.8 ± 1.4 at 6 months (P < 0.001). The mean ODI scores ± SD had also a significant improvement: 62.3 ± 17.2 preoperatively and 15.1 ± 6.0 at the 6-month follow-up (P < 0.001). Conclusion: This study suggests that type A2 vertebral fractures could be successfully treated by CT- and fluoroscopy-guided percutaneous vertebroplasty.

    Diabetes mellitus (DM) and metabolic syndrome are important targets for secondary prevention in cardiovascular disease. However, the prevalence in patients undergoing elective percutaneous coronary intervention is not well defined. We aimed to analyse the prevalence and characteristics of patients undergoing percutaneous coronary intervention with previously unrecognized prediabetes, diabetes and metabolic syndrome. Data were collected from 740 patients undergoing elective percutaneous coronary intervention between November 2010 and March 2013 at a tertiary referral center. Prevalence of DM and prediabetes was evaluated using Haemoglobin A1c (A1c ≥ 6.5% for DM, A1c 5.7-6.4% for prediabetes). A modified definition was used for metabolic syndrome [three or more of the following criteria: body mass index ≥30 kg/m2; triglycerides ≥ 150 mg/dL; high density lipoprotein prediabetes at time of percutaneous coronary intervention. Overall, 54.9% met criteria for metabolic syndrome (69.2% of patients with DM and 45.8% of patients without DM). Among patients undergoing elective percutaneous coronary intervention, a substantial number were identified with a new DM, prediabetes, and/or metabolic syndrome. Routine screening for an abnormal glucometabolic state at the time of revascularization may be useful for identifying patients who may benefit from additional targeting of modifiable risk factors.

    Six cases of paraplegic, post-traumatic spasticity, alleviated by percutaneous epidural neurostimulation with temporary or permanent implanted neuroelectrodes from the L1 to L4 intervertebral levels are presented. Modulation of this spasticity and secondary beneficial physiological effects were achieved, including regulation of bowel regimens, production of sweating and piloerection below the level of the lesion, and morning erections. The main advantages of percutaneous epidural neurostimulation in modulating spasticity are the avoidance of destructive neurosurgical procedures, the regulation of secondary physiological and autonomic responses, the avoidance of antispasticity medications, and the reversibility of the neurostimulation procedure.

    This cross-sectional observational study was designed to evaluate the uptake and outcome of patient education after percutaneous coronary intervention (PCI). A questionnaire containing 41 items was handed out to consecutive patients from randomly selected Swedish hospitals after PCI. Questions concerned the patient's attribution of the cause of the cardiac event, perception of the information provided by physicians and nurses, and a self-assessment of changes in lifestyle post PCI regarding tobacco, physical activity, food habits and stress. Replies were obtained from 1,073 patients (reply rate 67%). Non-modifiable risk factors (age, heredity) were attributed a higher rate as the cause of disease compared to modifiable factors (smoking, physical activity, food habits). Most patients (67%) perceived they were cured, and 38% perceived from the given information that there was no need to change their habits. A mere 27% reported that they still had cardiovascular disease and needed behavioural change. After PCI, 16% continued to use tobacco; half of these were offered smoking cessation support. In spite of an 80% referral rate to cardiac rehabilitation, one out of two patients did not enrol. Fewer than half were regularly physically active. Nutritional counselling was provided to 71%, but only 40% changed food habits. Stress management programmes were rarely provided. Current preventive practice scarcely meets the challenge posed by the progress in modern invasive cardiology. The Study of Patient Information after percutaneous Coronary Intervention (SPICI) motivates an in-depth revision and adaptation of cardiac rehabilitation programmes in order to improve patient understanding of the disease, and to support greater compliance with a cardioprotective lifestyle.

    Caecal perforation is a life-threatening complication of large bowel obstruction with a reported mortality of 34% to 72%. This case describes the novel use of percutaneous needle caecostomy as a life-saving measure to prevent imminent caecal perforation in a 68-year-old lady with large bowel obstruction secondary to an incarcerated incisional hernia. After careful review of computed tomography images and measurement of distances from the abdominal wall to the caecum, the patient's caecum was decompressed in the emergency department using a needle under local anaesthetic. The patient subsequently underwent laparoscopic hernia repair and had an uncomplicated recovery. When conducted safely and with precision in an appropriate patient, percutaneous needle caecostomy can provide immediate symptom relief, reduce risk of caecal perforation, and allow a laparoscopic surgical approach.

    The aim of this quasi-experimental study was to examine whether high-volume percutaneous coronary intervention (PCI) operators still maintain high volume and quality of outcomes when they moved to lower volume hospitals. Systematic reviews have indicated that high-volume PCI operators and hospitals have higher quality outcomes. However, little is known on whether high PCI volume and high quality outcomes are mainly due to operator characteristics (i.e., skill and experience) and is portable across organizations or whether it is due to hospital characteristics (i.e., equipment, team, and management system) and is less portable. We used Taiwan National Health Insurance claims data 2000-2012 to identify 98 high-volume PCI operators, 10 of whom moved from one hospital to another during the study period. We compared the PCI volume, risk-adjusted mortality ratio, and major adverse cardiovascular event (MACE) ratio before and after moving. Of the 10 high-volume operators who moved, 6 moved from high- to moderate- or low-volume hospitals, with median annual PCI volumes (interquartile range) of 130 (117-165) in prior hospitals and 54 (46-84) in subsequent hospitals (the hospital the operator moved to), and the remaining 4 moved from high to high-volume hospitals, with median annual PCI volumes (interquartile range) of 151 (133-162) in prior hospitals and 193 (178-239) in subsequent hospitals. No significant differences were observed in the risk-adjusted mortality ratios and MACE ratios between high-volume operators and matched controls before and after moving. High-volume operators cannot maintain high volume when they moved from high to moderate or low-volume hospitals; however, the quality of care is maintained. High PCI volume and high-quality outcomes are less portable and more hospital bound. © 2017 Wiley Periodicals, Inc.

    Percutaneous transhepatic catheter decompression is performed increasingly as an adjunct or alternative to surgery in patients with benign or malignant biliary obstruction. The authors recently saw three patients with cholangiocarcinoma in whom metastatic seeding of the peritoneal serosa was identified some months after initial percutaneous transhepatic biliary drainage. Although no tumor was found along the hepatic tract of the biliary drainage catheters to implicate the drainage tubes as the direct source of peritoneal spread, the occurrence of this rare type of metastasis of cholangiocarcinoma in patients with potential access of tumor cells to the peritoneal cavity via the catheter tracts does suggest such a relation.

    Percutaneous drainage of infected intraabdominal fluid collections is preferred over surgical drainage due to lower morbidity and costs. However, it can be a challenging procedure and catheter insertion carries the potential to contaminate the pleural space from the abdomen. This retrospective analysis demonstrates the clinical and radiographic correlation between percutaneous drainage of infected intraabdominal collections and the development of iatrogenic pleural space infections. A retrospective single institution analysis of 550 consecutive percutaneous drainage procedures for intraabdominal fluid collections was performed over 24 months. Patient charts and imaging were reviewed with regard to pleural space infections that were attributed to percutaneous drain placements. Institutional review board approval was obtained for conduct of the study. 6/550 (1.1%) patients developed iatrogenic pleural space infections after percutaneous drainage of intraabdominal fluid collections. All 6 patients presented with respiratory symptoms and required pleural space drainage (either by needle aspiration or chest tube placement), 2 received intrapleural fibrinolytic therapy and 1 patient had to undergo surgical drainage. Pleural effusion cultures revealed same bacteria in both intraabdominal and pleural fluid in 3 (50%) cases. A video with a dynamic radiographic sequence demonstrating the contamination of the pleural space from percutaneous drainage of an infected intraabdominal collection is included. Iatrogenic pleural space infections after percutaneous drainage of intraabdominal fluid collections occur at a low incidence, but the pleural empyema can be progressive requiring prompt chest tube drainage, intrapleural fibrinolytic therapy or even surgery. Expertise in intraabdominal drain placements, awareness and early recognition of this complication is critical to minimize incidence, morbidity and mortality in these patients.

    Background Bleeding following hospital discharge from percutaneous coronary intervention (PCI) is associated with increased risk of subsequent myocardial infarction (MI) and death, however the timing of adverse events following these bleeding events is poorly understood. Defining this relationship may help clinicians identify critical periods when patients are at highest risk. Methods and Results All patients undergoing PCI from 2004–2007 who survived to hospital discharge without a bleeding event were identified from the HMO Research Network-Stent Registry. Post-discharge rates and timing of bleeding-related hospitalizations, MI and death were defined. We then assessed the association between post-discharge bleeding-related hospitalizations with death and MI using Cox proportional hazards models. Among 8,137 post-PCI patients surviving to hospital discharge without in-hospital bleeding, 391 (4.8%) suffered bleeding-related hospitalization after discharge, with the highest incidence of bleeding-related hospitalizations occurring within 30 days of discharge (n=79, 20.2%). Post-discharge bleeding-related hospitalization after PCI was associated with subsequent death or MI (hazard ratio [HR] 3.09; 95% confidence interval [CI] 2.41–3.96), with the highest risk for death or MI occurring in the first 60 days after bleeding-related hospitalization (HR 7.16, CI 3.93–13.05). Conclusions Approximately 1 in 20 post-PCI patients are readmitted for bleeding, with the highest incidence occurring within 30 days of discharge. Patients suffering post-discharge bleeding are at increased risk for subsequent death or MI, with the highest risk occurring within the first 60 days following a bleeding-related hospitalization. These findings suggest a critical period after bleeding events when patients are most vulnerable for further adverse events. PMID:27301394

    Objective: To determine the successful rate, diagnostic accuracy and clinical usefulness of CT-guided percutaneous biopsy for the spine lesions. Methods: Eight-five patients (61 outpatients, 24 ward patients)underwent CT-guided percutaneous biopsy for the spine lesion. The imaging appearance of spinal lesions were lytic in 57 cases, osteosclerotic in 19 cases, and mixed in 9 cases. Biopsy specimens were sent for cytologic and histologic analysis in order to correct diagnosis. Bacterial studies were performed when ever infection was suspected. Results: The localization of puncture biopsy needle inside the spinal lesions, was conformed by computed tomography including 3 cervical, 26 thoracic, 37 lumbar, and 19 sacral lesions. Biopsy specimens included bone (29 cases), soft tissue (5 cases), mixed tissue (47 cases )and no specimen be obtained(4 cases). An adequate specimen for pathologic examination was obtained in 81 biopsies (95%). The pathologic examinations revealed 44 metastases, 17 primary bone neoplasms, 18 infections (included tuberculosis)and 2 normal tissues of vertebral body. The diagnostic accuracy reached 97.5% (79 of 81 patients). Conclusions: CT-guided percutaneous biopsy is an important tool in the evaluation of spinal lesions, providing accurate localization, less trauma and reliable pathologic diagnosis and worthwhile to be the routine before vertebroplasy.

    Full Text Available Background. B-type natriuretic peptide has been shown to be a very sensitive and specific marker of heart failure. In this study, we aimed to investigate the effect of percutaneous closure of ventricular septal defects with Amplatzer septal occluders on brain natriuretic peptide levels. Methods. Between 2008 and 2011, 23 patients underwent successfully percutaneous ventricular septal defect closure in 4 cardiology centers. Brain natriuretic peptide levels were measured in nine patients (4 male, mean ages were 25.3±14.3 who underwent percutaneous closure with Amplatzer occluders for membranous or muscular ventricular septal defects were enrolled in the study. Brain natriuretic peptide levels were measured one day before and one month after the closure. Patients were evaluated clinically and by echocardiography one month after the procedure. Results. Percutaneous closures of ventricular septal defects were successfully performed in all patients. There was not any significant adverse event in patients group during followup. Decrease in brain natriuretic peptide levels after closure were statistically significant (97.3±78.6 versus 26.8±15.6, =0.013. Conclusion. Brain Natriuretic Peptide levels are elevated in patients with ventricular septal defects as compared to controls. Percutaneous closure of Ventricular Septal Defect with Amplatzer occluders decreases the BNP levels.

    Objective: To discuss the therapeutic strategy and the clinical efficacy of percutaneous cholecystostomy in treating high-risk patients with acute cholecystitis. Methods: During the period of Jan. 2006-June 2008, percutaneous cholecystostomy was performed in 27 high-risk patients with acute cholecystitis, consisting of lithic cholecystitis (n = 21) and non-lithic cholecystitis (n = 6). Of 27 patients, percutaneous cholecystostomy via transhepatic approach was performed in 22 and via transperitoneal approach in 5. The 7 F drainage catheter was used. Cholecystography was conducted before the drainage catheter was extracted. Results: Percutaneous cholecystostomy was successfully accomplished in all 27 cases, with a technical success rate of 100%. Postoperative patency of gallbladder drainage was obtained in 25 patients, with the relieving or subsiding of abdominal pain and the restoring of temperature and leukocyte account to normal range within 72 hours. In one patient, as the abdominal pain relief was not obvious 72 hours after the procedure, cholecystography was employed and it revealed the obstruction of the drainage catheter. After reopening of the drainage catheter, the abdominal pain was relieved. In another case, cholecystography was carried out because the abdominal pain became worse after the procedure, and minor bile leak was demonstrated. After powerful anti-infective and symptomatic medication, the abdominal pain was alleviated. The drainage catheter was extracted in 25 patients 6-7 weeks after the treatment. Of these 25 patients, 12 accepted selective cholecystectomy, 7 received percutaneous cholecystolithotomy and 6 with non-lithic cholecystitis did not get any additional surgery. The remaining two patients were living with long-term retention of the indwelling drainage-catheter. Conclusion: Percutaneous cholecystostomy is a simple, safe and effective treatment for acute cholecystitis in high-risk patients. This technique is of great value in clinical

    The purpose of this study is to describe our experience with the role of CT-guided percutaneous drainage of loculated intra-abdominal collections consisting entirely of gas. An IRB-approved retrospective study analyzing patients with air-only intra-abdominal collections over an 8-year period was undertaken. Seven patients referred for percutaneous drainage were included. Size of collections, subsequent development of fluid, and microbiological yield were determined. Clinical outcome was also analyzed. Out of 2835 patients referred for percutaneous drainage between 2004 and 2012, seven patients (5M, 2F; average age 63, range 54-85) met criteria for inclusion with CT showing air-only collections. Percutaneous drain placement (five 8 Fr, one 10 Fr, and one 12 Fr) using Seldinger technique was performed. Four patients (57%) had recently undergone surgery (2 Whipple, 1 colectomy, 1 hepatic resection) while two (29%) had a remote surgery (1 abdominoperineal resection, 1 sigmoidectomy). Despite the lack of detectable fluid on the original CT, 6 patients (86%) had air and fluid aspirated at drainage, 5 (83%) of the aspirates developed positive microbacterial cultures. Four patients (57%) presented with fever at the time of the initial scan, all of whom had positive cultures from aspirated fluid. Four patients (57%) had leukocytosis, all of whom had positive cultures from aspirated fluid. Although relatively rare in occurrence, patients with air-only intra-abdominal collections with signs of infection should be considered for percutaneous management similar to that of conventional infected fluid collections. Although fluid is not visible on CT, these collections can produce fluid that contains organisms.

    To evaluate and describe the efficacy and side effects of a percutaneous thrombin injection under ultrasonography guidance for the treatment of iatrogenic pseudo aneurysms Eighteen consecutive iatrogenic pseudo aneurysm cases were treated with a thrombin injection. The thrombin was injected into the pseudo aneurysm cavity using a 22-gauge needle under ultrasonographic guidance. The causes of the pseudo aneurysms are as follows: post coronary angiography (9 cases), percutaneous coronary balloon angioplasty (5 cases), cerebral angiography (1 case), transhepatic chemo embolization (1 case), percutaneous trans femoral arterial stent insertion (1 case) and bone marrow aspiration for a marrow transplant (1 case). Only one case required a secondary thrombin injection due to recurrent flow in the pseudo aneurysm lumen, which was detected at the follow up Doppler ultrasound. Other seventeen cases were successfully treated on the first trial. There were no technical failures or complication related to the procedure. The average amount of thrombin injected was 733 IU. Nine out of 18 treated patients (50%) showed mild reactions to the thrombin including mild fever (4 cases), chilling sensation (3 cases), a chilling sensation with mild dyspnea (1 case), mild chest discomfort (1 case) after the thrombin injection. All these side effects were transient and improved several hours later. All the iatrogenic pseudo aneurysms were treated successfully with an ultrasound-guided percutaneous thrombin injection. There was a high rate of hypersensitivity to the bovine thrombin, which precaution should be taken to prevent more serious side effects

    Full Text Available Objectives: To investigate the aspects of return to work, socio-economic and quality of life aspects in 145 employed patients under 60 years of age treated with primary percutaneous coronary intervention for acute ST-elevation myocardial infarction. Material and Methods: During hospital treatment demographic and clinical data was collected. Data about major adverse cardiovascular events, rehabilitation, sick leave, discharge from job and retirement, salary, major life events and estimation of quality of life after myocardial infarction were obtained after follow-up (mean: 836±242 days. Results: Average sick leave was 126±125 days. Following myocardial infarction, 3.4% of patients were discharged from their jobs while 31.7% retired. Lower salary was reported in 17.9% patients, major life events in 9.7%, while 40.7% estimated quality of life as worse following the event. Longer hospitalization was reported in patients transferred from surrounding counties, those with inferior myocardial wall and right coronary artery affected. Age, hyperlipoproteinemia and lower education degree were connected to permanent working cessation. Significant salary decrease was observed in male patients. Employer type was related to sick leave duration. Impaired quality of life was observed in patients who underwent in-hospital rehabilitation and those from surrounding counties. Longer sick leave was observed in patients with lower income before and after myocardial infarction. These patients reported lower quality of life after myocardial infarction. Conclusions: Inadequate health policy and delayed cardiac rehabilitation after myocardial infarction may lead to prolonged hospitalization and sick leave as well as lower quality of life after the event, regardless of optimal treatment in acute phase of disease.

    Full Text Available Background: There have been a number of studies on mitral valve replacement and repeated percutaneous mitral balloon valvotomy for mitral valve restenosis after percutaneous mitral balloon valvotomy. However, studies on mitral valve repair for these patients are rare. In this study, we analyzed postoperative outcomes of mitral valve repair for mitral valve restenosis after percutaneous mitral balloon valvotomy. Methods: In this study, we assessed 15 patients (mean age, 47.7±9.7 years; 11 female and 4 male who underwent mitral valve repair between August 2008 and March 2013 for symptomatic mitral valve restenosis after percutaneous mitral balloon valvotomy. The mean interval between the initial percutaneous mitral balloon valvotomy and the mitral valve repair was 13.5±7 years. The mean preoperative Wilkins score was 9.4±2.6. Results: The mean mitral valve area obtained using planimetry increased from 1.16±0.16 cm2 to 1.62±0.34 cm2 (p=0.0001. The mean pressure half time obtained using Doppler ultrasound decreased from 202.4±58.6 ms to 152±50.2 ms (p=0.0001. The mean pressure gradient obtained using Doppler ultrasound decreased from 9.4±4.0 mmHg to 5.8±1.5 mmHg (p=0.0021. There were no early or late deaths. Thromboembolic events or infective endocarditis did not occur. Reoperations such as mitral valve repair or mitral valve replacement were not performed during the follow-up period (39±16 months. The 5-year event-free survival was 56.16% (95% confidence interval, 47.467–64.866. Conclusion: On the basis of these results, we could not conclude that mitral valve repair could be an alternative for patients with mitral valve restenosis after percutaneous balloon mitral valvotomy. However, some patients presented with results similar to those of mitral valve replacement. Further studies including more patients with long-term follow-up are necessary to determine the possibility of this application of mitral valve repair.

    Objective: To investigate the value of percutaneous transsplenic varices embolization (PTSVE) for treatment of upper gastrointestinal bleeding. Methods: Twenty cases with liver cirrhosis and portal hypertension suffered upper gastrointestinal bleeding. PTSVE was administered to them with hardener and coils. Among them, 8 cases had massive hepatocellular carcinoma (HCC) in right lobe; 10 cases with hepatocellular carcinoma had portal vein tumor thrombus and occlusion; the other two cases with liver cirrhosis had portal vein thrombosis. All of these cases were not suitable for percutaneous transhepatic varices embolization (PTHVE). PTSVE was performed under the guidance of fluoroscopy. Results: Technical success was achieved in 18 patients. A total of 35 gastric coronary veins were embolized. In all these cases, upper gastrointestinal bleeding stopped after PTSVE. There was no recurrence within 1 month follow-up. No serious complication occurred. Conclusion: PTSVE is a safe and efficient alternative treatment for upper gastrointestinal bleeding, especially for cases with portal vein occlusion or with massive HCC in right lobe of liver.

    Full Text Available BACKGROUND The first percutaneous endoscopic gastrostomy performed on a child was on June 12, 1979, at the Rainbow Babies and Children's Hospital, University Hospitals of Cleveland, Dr. Michael W.L. Gauderer, paediatric surgeon; Dr. Jeffrey Ponsky, endoscopist; and Dr. James Bekeny, surgical resident, performed the procedure on a 4 1 ⁄2-month-old child with inadequate oral intake. The authors of the technique, Dr. Michael W.L. Gauderer and Dr. Jeffrey Ponsky, first published the technique in 1980. In 2001, the details of the development of the procedure were published. Gastrostomy maybe indicated in numerous situations usually those in which normal or nutrition (or nasogastric feeding is impossible. The causes for these situations maybe neurological (e.g. stroke, anatomical (e.g. cleft lip and palate during the process of correction or other (e.g. radiation therapy for tumours in head and neck region. In certain situations where normal or nasogastric feeding is not possible, percutaneous endoscopic gastrostomy maybe of clinical benefit. This provides enteral nutrition (making use of the natural digestion process of the gastrointestinal tract despite bypassing the mouth; enteral nutrition is generally preferable to parenteral nutrition (which is only used when the GI tract must be avoided. The PEG procedure is an alternative to open surgical gastrostomy insertion and does not require a general anaesthetic; mild sedation is typically used. PEG tubes may also be extended into the small intestine by passing a jejunal extension tube (PEG-J tube through the PEG tube and into the jejunum via the pylorus. MATERIALS AND METHODS The present study was carried out in the Department of General Medicine on 32 patients who underwent PEG placement by gastroenterologist at Gayatri Vidya Parishad Hospital, Visakhapatnam, from January 2016 to December 2016. Patients were aged 18 years and above. All patients had placement of Ponsky pull PEs either in the

    Full Text Available Aim: The increased mortality and morbidity in diabetic patients who underwent cardiac surgery is well documented. However, there are few data about non-cardiac surgical interventions. This study is designed to evaluate whether diabetes has any effects on outcome of percutaneous nephrolithotomy (PNL. Methods: The records of 1658 patients who underwent PNL between October 2002 and December 2009 in our clinic were retrospectively analyzed. Data of patients with diagnosis of diabetes mellitus (group 1, 231 patients were compared with data of patients without diabetes (group 2, 1427 patients by means of operative and postoperative findings. Results: Complete stone clearance was achieved in 206 (89.1% patients in group 1 and 1355 (94.9% patients in group 2 (p:0.000. Auxiliary treatment modalities were needed in 44 (19.0% diabetic and 153 (10.7% non-diabetic patients (p:0.000. In diabetic patients, operation and hospitalization time, and time of nephrostomy tube removal were significantly longer. In addition, bleeding, fever and urosepsis rates were significantly higher in diabetic patients. Conclusion: PNL in diabetics is an effective procedure with acceptable complication rates in the treatment of renal stones. However, the increased risk of bleeding and infection needs extra attention in diabetic patients when compared with non-diabetics. (The Medical Bulletin of Haseki 2010; 48: 80-4

    Some challenging pathologic conditions of the biliary tract cannot be treated with endoscopy alone, and a combined approach with rendezvous techniques is frequently needed. Three different totally percutaneous rendezvous techniques were successfully applied in three cases. The rendezvous techniques were performed either with bilateral catheterization of bile ducts to treat a challenging type IV biliary stenosis and iatrogenic biliary damage or with biliary catheterization and percutaneous puncture of the anastomotic loop to treat a biliodigestive anastomosis failure with bile leakage.

    2010-06-01

    Interventional radiology plays a major role in the management of symptomatic intervertebral disc herniations. In the absence of significant pain relief with conservative treatment including oral pain killers and anti-inflammatory drugs, selective image-guided periradicular infiltrations are generally indicated. The precise control of needle positioning allows optimal distribution of steroids along the painful nerve root. After 6 weeks of failure of conservative treatment including periradicular infiltration, treatment aiming to decompress or remove the herniation is considered. Conventional open surgery offers suboptimal results and is associated with significant morbidity. To achieve minimally invasive discal decompression, different percutaneous techniques have been developed. Their principle is to remove a small volume of nucleus, which results in an important reduction of intradiscal pressure and subsequently reduction of pressure inside the disc herniation. However, only contained disc herniations determined by computed tomography or magnetic resonance are indicated for these techniques. Thermal techniques such as radiofrequency or laser nucleotomy seem to be more effective than purely mechanical nucleotomy; indeed, they achieve discal decompression but also thermal destruction of intradiscal nociceptors, which may play a major role in the physiopathology of discal pain. The techniques of image-guided spinal periradicular infiltration and percutaneous nucleotomy with laser and radiofrequency are presented with emphasis on their best indications.
