    Over the past decade, transcatheter interventions have become increasingly important in the treatment of patients with congenital heart lesions. These procedures may be broadly grouped as dilations (e.g., septostomy, valvuloplasty, angioplasty, and endovascular stenting) or as closures (e.g., vascular embolization and device closure of defects). Balloon valvuloplasty has become the treatment of choice for patients in all age groups with simple valvar pulmonic stenosis and, although not curative, seems at least comparable to surgery for congenital aortic stenosis in newborns to young adults. Balloon angioplasty is successfully applied to a wide range of aortic, pulmonary artery, and venous stenoses. Stents are useful in dilating lesions of which the intrinsic elasticity results in vessel recoil after balloon dilation alone. Catheter-delivered coils are used to embolize a wide range of arterial, venous, and prosthetic vascular connections. Although some devices remain investigational, they have been successfully used for closure of many arterial ducts and atrial and ventricular septal defects. In the therapy for patients with complex CHD, best results may be achieved by combining cardiac surgery with interventional catheterization. The cooperation among interventional cardiologists and cardiac surgeons was highlighted in a report of an algorithm to manage patients with tetralogy of Fallot or pulmonary atresia with diminutive pulmonary arteries, involving balloon dilation, coil embolization of collaterals, and intraoperative stent placement. In this setting, well-planned catheterization procedures have an important role in reducing the overall number of procedures that patients may require over a lifetime, with improved outcomes.

    Full Text Available Ultrasound (US examination of the bladder can precisely determine the bladder volume and is a useful tool in estimating the residual urine volume. Its application is consequently recommended as an alternative to catheterization for the determination of residual urine. Moreover it represents a simple, noninvasive method to predict the outcome of a voiding trial following acute urine retention based on intravesical prostatic protrusion and on the US pattern of the bladder content. In this article, the Authors review the implementation and results of a bladder US program developed for non-medical caregivers at one Emergency Department.

    By ultrasound scanning it was determined that respiratory movements made by chest of healthy and sick person are accompanied by respiratory chest rise of internal jugular veins. During the exhalation of an individual diameter of his veins increases and during the breath it decreases down to the complete disappearing if their lumen. Change of the diameter of internal jugular veins in different phases can influence significantly the results of vein puncture and cauterization in patients. The purpose of this research is development of the method increasing the efficiency and safety of cannulation of internal jugular veins by the ultrasound visualization. We suggested the method of catheterization of internal jugular veins by the ultrasound navigation during the execution of which the puncture of venous wall by puncture needle and the following conduction of J-guide is carried out at the moment of patient’s exhalation. This method decreases the risk of complications development during catheterization of internal jugular vein due to exclusion of perforating wound of vein and subjacent tissues and anatomical structures.

    The presence of pneumocephalus without a history of intracranial or intrathecal procedures is a significant radiographic finding. Although pneumocephalus means a violation of the dural barrier or the presence of infection, intravascular pneumocephalus is different from intraparenchymal pneumocephalus and its benign nature must be known in the presence of intravenous catheterization. Herein, we present a case of iatrogenic intravascular pneumocephalus with CT findings. To our knowledge, there are only a few reported cases of iatrogenic intravascular pneumocephalus in the literature. Careful intravenous catheterization and diagnosis of the condition on imaging helps to prevent unnecessary treatment procedures. (orig.)

    Central venous catheters (CVCs) are often used for various purposes in the emergency departments (ED). The main uses of CVCs in the EDs are emergent hemodialysis, in situations where peripheral vein catheterization cannot be achieved, and continuous invasive hemodynamic monitoring. The complications related to CVC insertion are usually mechanical and observed in the near term after the procedure. Retained CVC guidewire after catheterization is a rare complication in the published reports and usually related with intra- or postoperative settings and jugular or subclavian vein. The present study reported a young female patient who underwent left femoral vein catheterization 6 months earlier in an intensive care unit of another hospital and was diagnosed with complete guidewire retention in the ED. To the best of the authors' knowledge, this is the first case in published reports with a diagnosis of retained CVC guidewire with retrograde migration into the femoral vein. Surprisingly, the patient developed no thrombotic or embolic complication during this 6-month period. PMID:26657235

    Full Text Available Introduction: To propose a novel cannulation technique for difficult urethral catheterization procedures. Technique: The sheath tip of an intravenous catheter is cut off, replaced to the needle tip and pushed through the distal drainage side hole to Foley catheter tip, and finally withdrawn for cannulation. In situations making urethral catheterization difficult, a guide wire is placed under direct vision. The modified Foley catheter is slid successfully over the guide wire from its distal end throughout the urethral passage into the bladder. Results: The modified Foley catheter was used successfully in our clinic in cases requiring difficult urethral catheterization. Conclusions: This easy and rapid modification of a Foley catheter may minimize the potential complications of blind catheter placement in standard catheterization.

    2008-08-01

    Full Text Available PURPOSE: To review and compare the different methods for difficult male urethral catheterization described in selected literature. MATERIALS AND METHODS: A PubMed search was done with the terms "difficult", "failed", or "complications" and "urethral catheterization", "transurethral catheterization", "Foley catheter", "urethral catheter" or "filiforms and followers". All articles addressing the issue of difficult adult male urethral catheterization were included. RESULTS: Six main approaches were identified on the 14 articles included for review: 1 Passage of either a Glidewire, guide wire or filiform under direct vision; 2 Blind passage of a filiform, guide wire, Glidewire or hydrophilic catheter; 3 "The Peel-away® sheath placed on a cystoscope/resectoscope technique"; 4 "The rigid ureteroscope placed inside the 22F Foley technique"; 5 Suprapubic catheterization; and 6 "The instillation of 60 cc of saline through the catheter as it is advanced technique". CONCLUSION: There is a paucity of prospective data comparing the benefits, risks, success rates and complications of the different approaches for difficult Foley catheter placement. Our suggested approach starts with the initial attempt at urethral catheterization with an 18F coude and a 12F silicone catheter. If these fail, using a flexible cystoscope or the blind Glidewire technique are reasonable alternatives. If dilatation of a stricture is necessary, ureteric dilatators or a urethral balloon dilatator are recommended.

    Full Text Available Central venous catheterization is an invasive procedure commonly preferred for hemodynamic monitorization, total parenteral nutrition, cardiac pacemaker implantation, long-term use of vasoactive or irritating agents and hemodialysis. We present a 19-year-old woman with acute renal failure scheduled for hemodialysis catheterization. A catheter guidewire extending from the right internal jugular vein to the right external iliac vein was detected in the chest X-ray, taken two hours following catheterization after occurrence of arrhythmia and hypotension. Catheteter guidewire was extracted noninvasively without any complications. Most common reasons for this complication are stated to be attention deficits, lack of experience, overtired staff, and inadequate supervision of trainees. In this paper, we discussed this complication’s causes and preventive methods. (Journal of the Turkish Society Intensive Care 2011; 9:64-7

    Full Text Available Background: The aim of the present study was to evaluate the rejuvenation capacity among cardiac catheterization technicians occupationally exposed to ionizing radiation. Subjects and methods: The individual annual collective dose information was measured by thermoluminscent personal dosimeters (TLD for those technicians and found to be ranging between 2.16 and 8.44 mSv/y. Venous blood samples were obtained from 30 cardiac catheterization technicians exposed to X-ray during fluoroscopy procedures at the National Heart Institute in Embaba. The control group involved 25 persons not exposed to ionizing radiation and not working in hospitals in addition to 20 persons not exposed to ionizing radiation and working in hospitals. Blood samples were assayed for total and differential blood counts, micronucleus formation (FMN plasma stromal derived growth factor-1α (SDF-1 α and cell phenotype of circulating endothelial progenitor cells (EPCs, whose surface markers were identified as the CD34, CD133 and kinase domain receptors (KDR. Results: SDF-1α (2650± 270 vs. 2170 ± 430 pg/ml and FMN (19.9 ± 5.5 vs. 2.8 ± 1.4/1000 cells were significantly higher among cardiac catheterization staff compared to those of the controls respectively. Similarly, EPCs: CD34 (53 ± 3.9 vs. 48 ± 8.5/105 mononuclear cells, CD133 (62.4 ± 4.8 vs. 54.2 ± 10.6 /105 mononuclear cells KDR (52.7 ± 10.6 vs.43.5± 8.2 /105 mononuclear cells were also significantly higher among cardiac catheterization staff compared to the values of controls respectively. Smoking seemed to have a positive effect on the FMN and SDF-1 but had a negative effect on EPCs. It was found that among cardiac catheterization staff, the numbers of circulating progenitor cells had increased and accordingly there was an increased capacity for tissue repair.

    Full Text Available Background: The aim of this study was to determine the most appropriate time for urinary catheter removal following a gynecological surgery.Methods: Critical appraisal of clinical trial articles were conducted. It was aimed to answer our clinical question whether 24-hour postoperative urinary catheter removal is superior compared to other durations in avoiding postoperative urinary retention (PUR and urinary tract infection (UTI. The search was conducted on the Cochrane Library® and PubMed® using keywords “postoperative urinary retention”, “postoperative catheterization” and “urinary retention AND catheterization”. Reference lists of relevant articles were searched for other possibly relevant trials.Results: Seven articles were available as full text, then appraisals of six prospective RCTs involving 846 women underwent hysterectomy and vaginal prolapse surgery were performed finding at the re-catheterization and UTI rate. Subjects in earlier-removal groups were 3 to 4 times more likely to have re-catheterization (OR = 3.10-4.0 compared to later-removal groups, while they who have it removed on 5th day were 14 times more likely to develop UTI compared with immediate group (OR = 14.786, 95% CI 3.187- 68.595.Conclusion: The 24-hour catheterization policy in hysterectomy and vaginal prolapse surgery remains most appropriate although associated with an increased risk of re-catheterization. The removal of catheter before 24 hour (6 or 12 hour could be considered to be used as one of interventions in further RCT(s to find out the best duration which would result in lowest incidence in both of UTI and  PUR.

    Full Text Available Objectives: Urinary tract infection (UTI as a result of Candida spp. is becoming increasingly common in hospitalized setting. Clinicians face dilemma in differentiating colonization from true infection and whether to treat candiduria or not. The objective of the present study was to look into the significance of candiduria in catheterized patients admitted in the ICUs and perform microbiological characterization of yeasts to guide treatment protocols. Materials and Methods: One hundred consecutive isolates of Candida spp. from the urine sample of 70 catheterized patients admitted in the ICU were collected and stocked for further characterization. A proforma was maintained containing demographic and clinical details. Blood cultures were obtained from all these 70 patients and processed. Species identification of yeasts was done on VITEK. Results: Candiduria was more common at extremes of age. The mean duration of catheter days was 11.1 ± 6 days. Other associated risk factors such as diabetes mellitus and antibiotic usage were seen in 38% and 100% of our study group. Concomitant candidemia was seen in 4.3% of cases. Non-albicans Candida spp. (71.4% emerged as the predominant pathogen causing nosocomial UTI. Conclusion: The present study reiterates the presence of candiduria in catheterized patients, especially in the presence of diabetes and antibiotic usage. Non-albicans Candida spp. are replacing Candida albicans as the predominant pathogen for nosocomial UTI. Hence, we believe that surveillance for nosocomial candiduria should be carried out in hospitalized patients.

    Background. Multiple sclerosis (MS) healthcare providers (HCP) have undergone considerable educational efforts regarding the importance of evaluating and treating pelvic floor disorders, specifically, urinary dysfunction. However, limited data are available to determine the impact of catheterization on patient quality of life (QoL). Objectives. To describe the use of urinary catheterization among MS patients and determine the differences between those who report positive versus negative impact of this treatment on QoL. Methods. Patients were queried as part of the 2010 North American Research Committee On Multiple Sclerosis survey; topics included 1) urinary/bladder, bowel, or sexual problems; 2) current urine leakage; 3) current catheter use; 4) catheterizing and QoL. Results. Respondents with current urine leakage were 5143 (54.7%), of which 1201 reported current catheter use (12.8%). The types of catheters (intermittent self-catheterization and Foley catheter (indwelling and suprapubic)) did not differ significantly. Of the current catheter users, 304 (25.35%) respondents reported catheterization negatively impacting QoL, 629 (52.4%) reported a positive impact on QoL, and 223 (18.6%) reported neutral QoL. Conclusions. A large proportion of catheterized MS patients report negative or positive changes in QoL associated with urinary catheterization. Urinary catheterization does not appear to have a universally negative impact on patient QoL. PMID:25006498

  10. The present and future of interventional catheterization for congenital heart disease

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    @@Over the past decade, the focus of the pediatric catheterization laboratory has changed dramatically from its primary function of providing diagnosis to offering treatment.Since Rashkind first described the technique for atrial septostomy in the setting of complete transposition of the great arteries in 1966, therapeutic catheterization techniques have replaced conventional surgery, including both corrective and palliative surgeries, for many lesions. Interventional catheterization has become an important modality in the treatment of congenital heart disease. In addition, in the staged management of complex congenital heart disease, better outcomes have been acquired by combined surgical and interventional catheterization strategies. Although great advances have been made in the therapeutic catheterization for congenital heart disease in some Chinese medical centers, there is considerable difference in both clinical applications and basic researches between China and other developed countries. Thus, it is very important to expand this advanced technique aggressively but carefully.

    Full Text Available This paper presents a cross-functional effort in a US community hospital for an overall process improvement in its Cardiac Catheterization Lab (CCL. One of the key system performance metrics identified was the patient turnaround time. The objective of this study was to identify the sources of delays in the system that lead to prolonged patient turnaround time using a structured lean approach. A set of qualitative recommendations were proposed and implemented. Quantification of some of these recommendations and certain additional ‘what-if’ scenarios were evaluated using Discrete Event Simulation (DES. The simulation results showed that significant reduction in patient turnaround time could be achieved if the proposed recommendations were implemented. This study demonstrated the benefits of adopting the lean philosophy in the continuous process improvement journey in the healthcare delivery arena.

  12. Radiation Dose Estimation for Pediatric Patients Undergoing Cardiac Catheterization

    Science.gov (United States)

    Wang, Chu

    Patients undergoing cardiac catheterization are potentially at risk of radiation-induced health effects from the interventional fluoroscopic X-ray imaging used throughout the clinical procedure. The amount of radiation exposure is highly dependent on the complexity of the procedure and the level of optimization in imaging parameters applied by the clinician. For cardiac catheterization, patient radiation dosimetry, for key organs as well as whole-body effective, is challenging due to the lack of fixed imaging protocols, unlike other common X-ray based imaging modalities. Pediatric patients are at a greater risk compared to adults due to their greater cellular radio-sensitivities as well as longer remaining life-expectancy following the radiation exposure. In terms of radiation dosimetry, they are often more challenging due to greater variation in body size, which often triggers a wider range of imaging parameters in modern imaging systems with automatic dose rate modulation. The overall objective of this dissertation was to develop a comprehensive method of radiation dose estimation for pediatric patients undergoing cardiac catheterization. In this dissertation, the research is divided into two main parts: the Physics Component and the Clinical Component. A proof-of-principle study focused on two patient age groups (Newborn and Five-year-old), one popular biplane imaging system, and the clinical practice of two pediatric cardiologists at one large academic medical center. The Physics Component includes experiments relevant to the physical measurement of patient organ dose using high-sensitivity MOSFET dosimeters placed in anthropomorphic pediatric phantoms. First, the three-dimensional angular dependence of MOSFET detectors in scatter medium under fluoroscopic irradiation was characterized. A custom-made spherical scatter phantom was used to measure response variations in three-dimensional angular orientations. The results were to be used as angular dependence

    Full Text Available BACKGROUND AND OBJECTIVES: In this study, we aimed to clarify the importance of residency grade and other factors which influence the success of thoracic epidural catheterization in thoracotomy patients. METHODS: After the ethical committee approval, data were recorded retrospectively from the charts of 415 patients. All patients had given written informed consent. The thoracic epidural catheterization attempts were divided into two groups as second-third year (Group I and fourth year (Group II according to residency grade. We retrospectively collected demographic data, characteristics of thoracic epidural catheterization attempts, and all difficulties and complications during thoracic epidural catheterization. RESULTS: Overall success rate of thoracic epidural catheterization was similar between the groups. Levels of catheter placement, number and duration of thoracic epidural catheterization attempts were not different between the groups (p > 0.05. Change of needle insertion level was statistically higher in Group II (p = 0.008, whereas paresthesia was significantly higher in Group I (p = 0.007. Dural puncture and postdural puncture headache rates were higher in Group I. Higher body mass index and level of the insertion site were significant factors for thoracic epidural catheterization failure and postoperative complication rate and those were independence from residents' experience (p < 0.001, 0.005. CONCLUSION: Body mass index and level of insertion site were significant on thoracic epidural catheterization failure and postoperative complication rate. We think that residents' grade is not a significant factor in terms overall success rate of thoracic epidural catheterization, but it is important for outcome of these procedures.

    The sonographic findings in the bladder are presented in four children with myelomeningocele and neurogenic dysfunction of the bladder, who were treated with intermittent self-catheterization and intravesical oxybutinin chloride. All were referred for routine sonography of the urinary tract. Each had infused a crushed tablet of oxybutinin chloride intravesically 30-120 min before the examination. In two children, brightly echogenic, non-shadowing particles were suspended in the bladder urine. In one of these, the particles swirled giving the impression of a "snowstorm"; in the other, most of the particles gradually settled forming an irregular clump on the bladder base. In the remaining two children, the urine appeared diffusely hazy with innumerable tiny particles giving the impression of a fine mist filling the bladder. The sonographic appearance of the urine in the bladder after intravesical instillation of crushed tablets can be dramatic and can simulate pus, blood, fungus, or other debris in the bladder lumen. In the absence of clinical symptoms or hematuria, a history of recent infusion of medication into the bladder should be sought.

    Full Text Available This report describes the case of an eighty-two-year old lady with an indwelling urethral catheter inserted eight years prior to her presentation to manage her urinary incontinence. She underwent radiotherapy for muscle-invasive bladder cancer (stage T2b in 1991 and had a laparotomy and drainage of an appendicular abscess in her early twenties. She presented with a short history of fecaluria, pneumaturia, and passage of urine per rectum. On laparotomy she was found to have an inflated catheter balloon that has eroded through the bladder wall into the lumen of a terminal ileal segment. To our knowledge this is the first reported case in literature of a patient developing an enterovesical fistula as a result of a urethral catheter eroding through the bladder wall into the bowel lumen. There are numerous known complications of long-term urethral catheterization. They include recurrent urinary tract infections, recurrent pyelonephritis, sepsis, urethral stricture, blocked and retained catheters, among many other reported complications. This case describes an unusual presentation secondary to an even more unusual complication. This should be considered when handling patients with indwelling urethral catheters inserted in unhealthy bladders.

  1. Optimization of radiation protection in pediatric cardiac catheterization procedures

    International Nuclear Information System (INIS)

    Cardiac catheterization is among the interventional radiology procedures considered to give high doses to adult and pediatric patients. However, almost every year, the number of pediatric patients undergoing these procedures tends to increase. The King Faisal Specialist Hospital and Research Centre (KFSH and RC) is a tertiary level medical center in Riyadh, Kingdom of Saudi Arabia with a 600 bed capacity. Diagnostic X ray procedures (radiography and fluoroscopy) average to about 150,000 annually. Pediatric cardiac catheterization procedures average to about 2,000 cases annually. Due to the limited published data on radiation doses to pediatric patients undergoing these procedures, a study was conducted to assess the doses in pediatric patient undergoing cardiac catheterization procedures and to determine the factors contributing to high doses. Patient and occupational doses during interventional procedures depend on procedure type, fluoroscopy time, number of images, equipment performance and training of the interventionist. KFSH and RC has four X ray rooms in its Cardiac Catheterization Laboratory. There is only one X ray room that is dedicated for pediatric procedure and it was selected for the study. This room is equipped with a Siemens Bicor + biplane X ray unit with HVL of 3.5 mm Al each for the two X ray tubes. The equipment geometry allows the system to have X ray beams in the vertical, horizontal and oblique directions. The system has a built-in DAP meter. Data on quality control tests and DAP calibration performed by the in-house biomedical engineer of Siemens was retrieved. The DAP calibration data supplied by the engineer were verified using a Diamentor M1 (PTW, Freiburg, Germany) DAP meter and following the NRPB protocol. Results of the quality control tests on the X ray machine generator were investigated. The dose area product values from records of pediatric patients in the age groups of 0 (neonates), 1, 5 and 10 years on four common procedures were

    The Multipurpose technique for coronary arteriography employs a single catheter. The benefits are a reduction in the cost of the procedure and a shorter procedural time by experienced operators. To enhance the performance of these catheters, a modification was made in the materials and tip design, and these modifications were clinically evaluated in a small study. Compared to the control group of patients (n = 41), patients catheterized with the Multipurpose-SM (n = 43) were shown to have a shorter procedural time as measured by a reduced fluoroscopy time (7.08 min vs. 9.52 min, P = .007). This difference is statistically significant at a 95% confidence level and resulted in less radiation exposure to the operator and cath lab staff. The procedural time was significantly reduced by fewer catheter exchanges (19% study vs. 46% control; P = .006), which were needed to successfully complete the procedure. The new Multipurpose-SM catheter also demonstrated enhanced flexibility for cannulating coronary arteries with superior or anterior takeoffs. This study concludes that the utilization of a modified Multipurpose-SM catheter is safe and effective in cannulating both the left and right coronary arteries, bypass grafts, and performing left ventriculography. The primary benefits of using this modified catheter are reduced fluoroscopy time and the need for fewer catheter exchanges. PMID:7834732

    Background and Objectives Right heart catheterization is traditionally performed using a femoral vein approach that involves admission, bed rest, and risks of bleeding and hematoma. Recent studies have confirmed safety of the use of forearm vein for right cardiac catheterization. In the present study, we evaluated the feasibility of right cardiac catheterization via the antecubital fossa vein in Korean patients. Subjects and Methods The medical records of all patients who underwent right heart catheterization at our hospital between January 2003 and December 2014 were reviewed retrospectively. Right cardiac catheterizations via the antecubital fossa vein and the femoral vein were compared in terms of demographic data (age, sex, weight, height, and body mass index), indications for right cardiac catheterization, and procedural and outcome data (initial success rate, procedure time, compression to ambulation time, and complications). Results We reviewed 132 cases (antecubital fossa vein approach, n=37; femoral vein approach, n=95). The demographic data, initial success rate (100% vs. 100%) and procedure time (21.6±16.8 min vs. 25.6±12.6 min, p=0.14) were similar in both groups. The antecubital fossa vein group had a shorter mean compression to ambulation time than the femoral vein group (0.0 min vs. 201.2±48.1 min, p<0.01). No complications were observed in either group. Conclusion Our study indicated the ease of performance of right cardiac catheterization via the antecubital fossa vein. Thus, the antecubital fossa vein can be an alternative access site for right cardiac catheterization in Korean patients. PMID:27014351

    Catheter-associated urinary tract infections (CAUTI) are the most common hospital-associated infections. Here, we report that bladder catheterization initiated a persistent sterile inflammatory reaction within minutes of catheter implantation. Catheterization resulted in increased expression of genes associated with defense responses and cellular migration, with ensuing rapid and sustained innate immune cell infiltration into the bladder. Catheterization also resulted in hypersensitivity to Enterococcus faecalis and uropathogenic Escherichia coli (UPEC) infection, in which colonization was achieved using an inoculum 100-fold lower than the ID90 for infection of an undamaged urothelium with the same uropathogens. As the time of catheterization increased, however, colonization by the Gram-positive uropathogen E. faecalis was reduced, whereas catheterization created a sustained window of vulnerability to infection for Gram-negative UPEC over time. As CAUTI contributes to poorer patient outcomes and increased health care expenditures, we tested whether a single prophylactic antibiotic treatment, concurrent with catheterization, would prevent infection. We observed that antibiotic treatment protected against UPEC and E. faecalis bladder and catheter colonization as late as 6 hours after implantation. Thus, our study has revealed a simple, safe, and immediately employable intervention, with the potential to decrease one of the most costly hospital-incurred infections, thereby improving patient and health care economic outcome.

    Full Text Available Guramrinder S Thind,1 Raunak Parida,1 Nishant Gupta2 1SDM College of Medical Sciences and Hospital, Dharwad, Karnataka, India; 2University of Texas at Houston, Houston, TX, USAAbstract: Many recent innovations have been made in developing new antiplatelet and ­anticoagulant drugs in the last few years, with a total of nine new antithrombotic drugs approved by the Food and Drug Administration after the year 2000. This has revolutionized the medical therapy given to manage acute coronary syndrome and support cardiac catheterization. The concept of dual antiplatelet therapy has been emphasized, and clopidogrel has emerged as the most-popular second antiplatelet drug after aspirin. Newer P2Y12 inhibitors like prasugrel and ticagrelor have been extensively studied and compared to clopidogrel. The role of glycoprotein (Gp IIb/IIIa inhibitors is being redefined. Other alternatives to unfractionated heparin have become available, of which enoxaparin and bivalirudin have been studied the most. Apart from these, many more drugs with novel therapeutic targets are being studied and are currently under development. In this review, current evidence on these drugs is presented and analyzed in a way that would facilitate decision making for the clinician. For this analysis, various high-impact clinical trials, pharmacological studies, meta-analyses, and reviews were accessed through the MEDLINE database. Adopting a unique interdisciplinary approach, an attempt has been made to integrate pharmacological and clinical evidence to better understand and appreciate the pros and cons of each of these classes of drugs.

The authors hypothesized that a catheterization threshold of 800 ml was superior to 500 ml in reducing postoperative urinary catheterization and urological complications after fast-track total hip...... and understood Danish. Participants were randomly allocated to a catheterization threshold of 500 or 800 ml, using opaque sealed envelopes. Group assignment was unmasked. Ultrasound bladder scans were performed every second hour until the first voluntary micturition, with subsequent urinary catheterization......-protocol analysis (20 did not complete the study and 59 were excluded from the analysis). In the 500-ml group, 32.2% received catheterization (114 of 354) compared to 13.4% (49 of 367) in the 800-ml group (relative risk, 0.4; 95% CI, 0.3 to 0.6; P

  9. Routine preoperative cardiac catheterization necessary before repair of secundum and sinus venosus atrial septal defects

    International Nuclear Information System (INIS)

    Between January 1976 and July 1983, 217 patients with atrial septal defect underwent surgical repair at Children's Hospital. Thirty with a primum atrial septal defect and 26 who underwent cardiac catheterization elsewhere before being seen were excluded from analysis. Of the 161 remaining patients, 52 (31%) underwent preoperative cardiac catheterization, 38 because the physical examination was considered atypical for a secundum atrial septal defect and 14 because of a preexisting routine indication. One hundred nine (69%) underwent surgery without catheterization, with the attending cardiologist relying on clinical examination alone in 5, additional technetium radionuclide angiocardiography in 5, M-mode echocardiography in 13 and two-dimensional echocardiography in 43; both M-mode echocardiography and radionuclide angiography were performed in 24 and two-dimensional echocardiography and radionuclide angiography in 19. Since 1976, there has been a trend toward a reduction in the use of catheterization and use of one rather than two noninvasive or semiinvasive techniques for the detection of atrial defects. Of the 52 patients who underwent catheterization, the correct anatomic diagnosis was made before catheterization in 47 (90%). Two patients with a sinus venosus defect and one each with a sinus venosus defect plus partial anomalous pulmonary venous connection, partial anomalous pulmonary venous connection without an atrial septal defect and a sinoseptal defect were missed. Of 109 patients without catheterization, a correct morphologic diagnosis was made before surgery in 92 (84%). Nine patients with a sinus venosus defect, three with sinus venous defect and partial anomolous pulmonary venous connection, four with partial anomalous pulmonary venous return without an atrial septal defect and one with a secundum defect were incorrectly diagnosed.(ABSTRACT TRUNCATED AT 250 WORDS)

    In the clinic 1442 catheterizations were performed, 1156 of them being catheterizations of the subclavian vein. Dangerous complications such as punctures of the posterior wall of the subclavian vein in combination with injuries of the pleura cupola and apex pulmonis were observed three times. Hemo-, hydro- and pneumothorax accompanying these complications in different combinations are contraindications to repeated puncture and catheterization of the subclavian vein both in the left and in the right. Recommendations are given to reduced possible complications.

    Outpatient cardiac catheterization is frequently performed, but the optimal recovery time after sheath removal has not been defined. Left heart catheterization was performed via the femoral artery utilizing 6 French catheters on 323 outpatients. One hundred thirty-five patients were randomized to ambulate at a mean of 2.5 hr (group 1) after puncture site compression, whereas 188 patients were randomized to ambulate at a mean of 4.1 hr (group 2). Telephone follow-up occurred within 48 hr. A small hematoma (< 5 cm) occurred in 2 (1.6%) patients in group 1 and in 4 (2.4%) patients in group 2. These results indicate that it is safe to ambulate patients 2.5 hr following 6 French diagnostic heart catheterization. PMID:9286529

    Full Text Available UTI is the most common infection in all ages and urinary catheters especially long-term catheterization are important predisposing factors of UTI. Urinary catheters are used in different hospital wards as a complementary curative method for the patients who are undergone various surgical procedures, such as : cesarean, hysterectomy , laparotomy, etc and they who are unable to control their voided urine . 226 urine specimens were collected from 119 catheterized patients which had been hospitalized in seven wards of Razi and Golestan hospitals in Ahwas city . At least two urine specimens were collected from each patient , before and after the insertion of the catheter . All of the specimens were inoculated to suitable Media, after transportation to the Microbiology Lab . Isolated colonies were identified and their resistance patterns were determined by the standard disk diffusion method (Kirby –Bauer procedure to 8 different antibiotics. 38 cases (43.6% out of 87 patients showed Bacteriuria in the end of catheterization . They had no bacteriuria symptoms or sign before the catheterization. The most cases(28.9% of bacteriuria occured in 30-39 years group and the lowest cases (2.6 % of them occured in 60-69 years group. Out of 50 bacterial strains isolated from urine cultures , E.coil (with 17 cases was the highest (34% and Staphylococcus aureus , Klebsiella pneumoniae , Edwardsiella tarda , Enterobacter sakazakii (with 2% for each were the lowest cases. E.coli, Enterobacter and Kl. rhinoscleromatis , showed the most resistance to Ampicillin, Penicillin , Cephalexin , and the lowest rate to Nalidixic acid, Gentamicin and Nitrofurantoin . Staphylococcus epidermidis isolates ,also,showed the most resistance (100% to Penicillin and Ampicillin , and the lowest rate to Gentamicin (with 66.7%, Cotrimoxazol and Nitrofurantoin (with 50% .The results of this study suggested that catheterization , especially long- term catheterization causes the rise of

    International Nuclear Information System (INIS)

    Rupture of the pulmonary artery or one of its branches during Swan-Ganz catheterization is a complication that is rare but remains fatal in almost 50% of cases. The risk factors and mechanisms involved in the pathogenesis of this accident have been widely reported. Management is twofold: resuscitation procedures and specific medical or even surgical treatment. We report a case of pulmonary artery rupture occurring during Swan-Ganz catheterization that was treated by coil embolization. This technique, which is quick and simple to use, would appear to be very promising. This is the first case of successful emergency treatment of pulmonary artery rupture using an endovascular technique

    The percutaneous punction of the radial artery for catheterization procedures has gained acceptance lately. This was a consequence of achieving results similar to the femoral approach, with the benefits of a lower rate of complications and increased comfort for the patients post procedure. Recently it has gained an additional impulse with the better prognosis obtained in acute coronary syndromes. In this trial we have evaluated if the feasibility, results and advantages related with the use of the radial artery percutaneous approach to perform catheterization procedures, continues when used in patients who have had a previous brachial artery cutdown. Out of a total of 1356 percutaneous radial accesses, 53 were in patients with previous brachial artery cutdown. Through this access 71 catheterization procedures were performed, achieving access success in 96.2% (51/53) of the punctions. Once the access success was obtained, 93.6% (44/47) of the diagnostic procedures and 100% (24/24) of the therapeutics procedures were successful. During hospitalization, in this group of patients, no major adverse cardiac events occurred and there was a 1.4% (1/71) rate of minor events. At seven days follow up, no new complications were recorded. Although this is a small group, we believe that it is enough to show that percutaneous punctions of the radial artery to perform catheterization procedures, in patients with previous brachial artery cutdown, are feasible, allowing high access and procedure success rates, with a low frequency of complications.

    The aims of the present study were to develop a device for vaginal and transcervical catheterization in domestic cats, and to study cervical patency during the various stages of the oestrous cycle. Seventeen queens submitted for routine spaying were included in the study. A vaginal catheter was designed from a urinary catheter for dogs, to fit into the ventral vaginal fornix, and a 3.5 French tomcat catheter was used as an inner transcervical catheter. Cervical patency was studied by infusing 0.5 ml Urografin into the cranial vagina and taking X-rays of the queens after 5 min. The Urografin did not enter the uterus, even in the oestrous queens. Transcervical catheterization was then attempted. The correct placement of the intrauterine catheter was confirmed by injecting green food colour mixed with penicillin G and observing the presence of stain in the uterine horns during surgery. Catheterization was successful in 13 of 17 queens: six of nine in interoestrus, three of three in oestrus, one of two in metoestrus and three of three in the postpartum period. Transcervical catheterization is a non-invasive technique that is likely to improve the success rate of assisted feline reproduction, and is potentially a useful non-surgical technique for diagnosis and therapy of uterine diseases.

    Acute kidney injury (AKI) is closely associated with the mortality of hospitalized patients and long-term development of chronic kidney disease, especially in children. The purpose of our study was to assess the evidence of contrast-induced AKI after cardiac catheterization in children with heart disease and evaluate the clinical usefulness of candidate biomarkers in AKI. A total of 26 children undergoing cardiac catheterization due to various heart diseases were selected and urine and blood samples were taken at 0 hr, 6 hr, 24 hr, and 48 hr after cardiac catheterization. Until 48 hr after cardiac catheterization, there was no significant increase in serum creatinine level in all patients. Unlike urine kidney injury molecule-1, IL-18 and neutrophil gelatinase-associated lipocalin, urine liver-type fatty acid-binding protein (L-FABP) level showed biphasic pattern and the significant difference in the levels of urine L-FABP between 24 and 48 hr. We suggest that urine L-FABP can be one of the useful biomarkers to detect subclinical AKI developed by the contrast before cardiac surgery.

    Newer echocardiographic techniques may allow for more accurate assessment of left ventricular (LV) function. Adult studies have correlated these echocardiographic measurements with invasive data, but minimal data exist in the pediatric congenital heart population. Purpose of this study was to evaluate which echocardiographic measurements correlated best with LV systolic and diastolic catheterization parameters. Patients with two-ventricle physiology who underwent simultaneous echocardiogram and cardiac catheterization were included. Images were obtained in the four-chamber view. LV systolic echocardiographic data included ejection fraction, displacement, tissue Doppler imaging (TDI) s' wave, global longitudinal strain, and strain rate (SR) s' wave. Diastolic echocardiographic data included mitral E and A waves, TDI e' and a' waves, and SRe' and SRa' waves. E/TDI e', TDI e'/TDI a', E/SRe', and SRe'/SRa' ratios were also calculated. Catheterization dP/dt was used as a marker for systolic function, and LV end-diastolic pressure (EDP) was used as a marker for diastolic function. Correlations of the echocardiographic and catheterization values were performed using Pearson correlation. Twenty-nine patients were included (14 females, 15 males). Median age at catheterization was 3.4 years (0.04-17.4 years). dP/dt was 1258 ± 353 mmHg/s, and LVEDP was 10.8 ± 2.4 mmHg. There were no significant correlations between catheterization dP/dt and systolic echocardiographic parameters. LVEDP correlated significantly with SRe' (r = -0.4, p = 0.03), SRa' (r = -0.4, p = 0.03), and E/SRe' (r = 0.5, p = 0.004). In pediatric congenital heart patients, catheterization dP/dt did not correlate with echocardiographic measurements of LV systolic function. Further studies are needed to determine which echocardiographic parameter best describes LV systolic function in this population. Strain rate analysis significantly correlated with LVEDP. Strain rate analysis should be considered as an

    Background Femoral artery thrombosis is one of the most common complications of catheterizations in infants and young children. This study was conducted to investigate the feasibility and effectiveness of thrombolytic therapy for femoral artery thrombosis after left cardiac catheterization in children.Methods Thrombolytic therapy with urokinase was carried out in children with femoral artery thrombosis after left cardiac catheterization. Each patient was given a bolus injection of heparin (100 U/kg). A bolus of urokinase (30 000-100 000 U) was injected intravenously, and then a continuous infusion of 10 000-50 000 U/h was administered. Transcatheter thrombolysis was performed once previous procedures failed.Results Eight patients (aged (3.1±2.3) years (8 months to 7 years), body weight (13.1±4.2) kg (7 to 20 kg)) presented lower limbs ischemia alter left cardiac catheterizations was performed. Seven patients accepted thrombolytic therapy with urokinase. In 5 patients, peripheral intravenous thrombolysis was successful with restoration of a normal pulse. In the other 3 cases, peripheral intravenous thrombolysis failed, followed by successful transcatheter thrombolysis. The average duration of therapy was (7.25±5.31) hours (1-17 hours). The average doses of heparin and urokinase were (1600±723) U (800-3000 U) and (268 571±177 240) U (50 000-500 000 U), respectively. There were no statistically significant differences in partial thromboplastin time before and during urokinase therapy ((40.6±22.3) to (49.9±39.2) seconds). However, the prothrombin time was significantly longer ((12.7±9.58) to (48.1±18.6) seconds, P<0.05). Patency of the target vessel was evaluated in all the patients for 2 weeks and no occlusion recurred.Conclusion Thrombolytic therapy with urokinase is a safe and useful modality in children with femoral artery thrombosis after left cardiac catheterization.

    Full Text Available Abstract Background There is variation in cardiac catheterization utilization across jurisdictions. Previous work from Alberta, Canada, showed no evidence of a plateau in the yield of high-risk disease at cardiac catheterization rates as high as 600 per 100,000 population suggesting that the optimal rate is higher. This work aims 1 To determine if a previously demonstrated linear relationship between the yield of high-risk coronary disease and cardiac catheterization rates persists with contemporary data and 2 to explore whether the linear relationship exists in other jurisdictions. Methods Detailed clinical information on all patients undergoing cardiac catheterization in 3 Canadian provinces was available through the Alberta Provincial Project for Outcomes Assessment in Coronary Heart (APPROACH disease and partner initiatives in British Columbia and Nova Scotia. Population rates of catheterization and high-risk coronary disease detection for each health region in these three provinces, and age-adjusted rates produced using direct standardization. A mixed effects regression analysis was performed to assess the relationship between catheterization rate and high-risk coronary disease detection. Results In the contemporary Alberta data, we found a linear relationship between the population catheterization rate and the high-risk yield. Although the yield was slightly less in time period 2 (2002-2006 than in time period 1(1995-2001, there was no statistical evidence of a plateau. The linear relationship between catheterization rate and high-risk yield was similarly demonstrated in British Columbia and Nova Scotia and appears to extend, without a plateau in yield, to rates over 800 procedures per 100,000 population. Conclusions Our study demonstrates a consistent finding, over time and across jurisdictions, of linearly increasing detection of high-risk CAD as population rates of cardiac catheterization increase. This internationally-relevant finding

    Background Several million subclavian-vein catheters are placed in patients each year to enable caregivers to administer chemotherapy, total parenteral nutrition, or long-term antibiotics or to manage preoperative fluids. Subclavian venipuncture requires the position of a deep vein to be identified with only surface landmarks. But the traditional right subclavian vein (RSV) catheterization (primitive procedures) is not the answer for all patients. The precise location of the vein is not known, and it is important to select the most appropriate method to achieve central venous access safely in any given patient. To modify the primitive procedures of the RSV catheterization for greater success and reduce the complications, anatomic studies and ultrasonography were conducted and clinical applications were validated.Methods Anatomical observation and measurement of the RSV and its adjacent structures were performed on 20 adult cadavers according to modified procedures. The RSV catheterization of 2900 cases was carried out by the modified procedure, 500 of these cases were observed by ultrasonography after the operation.Results The anatomical studies and clinical application showed that the insertion point differs from the bodily form of fatness or leptosome. The clinical data revealed that in the 2900 cases which were performed with the modified approach, the success rate was 98.90% (2868 cases), the failure rate was 1.10% (32 cases), and the complication rate is 0.79% (23 cases), and the catheterization time is (31.2±10.5) minutes. Five hundred and sixty cases of the RSV catheterization were carried out by the recommended insertion procedure; the results were compared with the modified approach and the traditional approach. The successful rate of the traditional approach was 73.0%, of which the complication rate was 6.1%; the two approaches were significantly different (successful rate: χ2=626.642, P<0.01; complication rate: χ2=80.708, P<0.01).Conclusions The

    Full Text Available The bases and technical cares for the neuro-radiological study of the aorto-cervical and spinal vessels employing the retrograde catheterization according to Seldinger technic and with the Odman-Ledin catheters are reported. The authors recommend type II neuroleptanalgesia as anesthesical sedative and the use of percutaneous punction of the femoral artery or, by choice, of the axilar or humeral artery. For the selective catheterization by femoral via, they make previously an aortography, in order to know the anatomy of the supra-aortic vessels, with control through the image-inten-sifier or fluoroscopy. They employ manual injection for the study of the supra-aortic vessels and a Gidlung injector for the contrast of the ascending aorta. Complications are discussed.

  9. The value of cardiac catheterization and cineangiography in infantile lobar emphysema

    International Nuclear Information System (INIS)

    Lobar emphysema is an uncommon cause of respiratory distress in infancy. Congenital heart disease is seen in about 20% of the patients with infantile (congenital) lobar emphysema. We described six infants with lobar emphysema. In three of them a congenital heart disease was demonstrated by cardiac catheterization and cineangiography; two had a tetralogy of Fallot with right aortic arch and the third infant a ventricular septal defect. The pulmonary angiography showed stretching of the arteries with very poor filling of the peripheral arteries and a characteristic smaller pulmonary vein in the affected lobe. In all the six patients the pulmonary artery pressure was normal. All the patients underwent lobectomy with good results. We feel that a preoperative cardiac catheterization and cineangiography is of value in this very sick group of infants. (orig.)

    Full Text Available Background It is believed that healthcare staff play an important role in minimizing complications related to urethral catheterization. The purpose of this study was to determine whether or not healthcare staff complied with the standards for urethral catheterization. Methods This study was conducted in Imam Reza teaching hospital, Tabriz, Iran, from July to September 2013. A total of 109 catheterized patients were selected randomly from surgical and medical wards and intensive care units (ICUs. A questionnaire was completed by healthcare staff for each patient to assess quality of care provided for catheter insertion, while catheter in situ, draining and changing catheter bags. Items of the questionnaire were obtained from guidelines for the prevention of infection. Data analysis was performed with SPSS 16. Results The mean age of the patients was 50.54 ± 22.13. Of the 109 patients, 56.88% were admitted to ICUs. The mean duration of catheter use was 15.86 days. Among the 25 patients who had a urinalysis test documented in their hospital records, 11 were positive for urinary tract infection (UTI. The lowest rate of hand-washing was reported before bag drainage (49.52%. The closed drainage catheter system was not available at all. Among the cases who had a daily genital area cleansing, in 27.63% cases, the patients or their family members performed the washing. In 66.35% of cases, multiple-use lubricant gel was applied; single-use gel was not available. The rate of documentation for bag change was 79%. Conclusion The majority of the guideline statements was adhered to; however, some essential issues, such as hand hygiene were neglected. And some patients were catheterized routinely without proper indication. Limiting catheter use to mandatory situations and encouraging compliance with guidelines are recommended.

    Purpose: Diagnosis and treatment of cardiovascular disease in the cardiac catheterization laboratory is often aided by a multitude of imaging technologies. The purpose of this work is to highlight the contributions to patient care offered by the various imaging systems used during cardiovascular interventional procedures. Methods: Imaging technologies used in the cardiac catheterization lab were characterized by their fundamental technology and by the clinical applications for which they are used. Whether the modality is external to the patient, intravascular, or intracavity was specified. Specific clinical procedures for which multiple modalities are routinely used will be highlighted. Results: X-ray imaging modalities include fluoroscopy/angiography and angiography CT. Ultrasound imaging is performed with external, trans-esophageal echocardiography (TEE), and intravascular (IVUS) transducers. Intravascular infrared optical coherence tomography (IVOCT) is used to assess vessel endothelium. Relatively large (>0.5 mm) anatomical structures are imaged with x-ray and ultrasound. IVUS and IVOCT provide high resolution images of vessel walls. Cardiac CT and MRI images are used to plan complex cardiovascular interventions. Advanced applications are used to spatially and temporally merge images from different technologies. Diagnosis and treatment of coronary artery disease frequently utilizes angiography and intra-vascular imaging, and treatment of complex structural heart conditions routinely includes use of multiple imaging modalities. Conclusion: There are several imaging modalities which are routinely used in the cardiac catheterization laboratory to diagnose and treat both coronary artery and structural heart disease. Multiple modalities are frequently used to enhance the quality and safety of procedures. The cardiac catheterization laboratory includes many opportunities for medical physicists to contribute substantially toward advancing patient care.

    Birkhäuser, Frédéric D; Studer, Urs E

    2015-01-01

    Acute urinary retention is a common emergency condition in elderly men. Transurethral and suprapubic catheterization are easy and safe procedures provided that a few simple rules are followed. Primarily, a transurethral catheter is placed if there is no urethral injury or stricture. Local anaesthesia of the urethra up to the sphincter region and a well-stretched penis warrant an atraumatic insertion of the catheter into the bladder. The use of a thick catheter with a round tip or of a catheter with a bended tip under rectal guidance facilitate the insertion of the catheter in difficult conditions. Alternatively, a suprapubic catheterization can be performed provided that no contraindication such as history or suspicion of transitional cell carcinoma is present. Optimal interventional conditions using ultrasound-guidance are mandatory in patients after abdominal surgery and with hemorrhagic diathesis in view of a safe and straight-forward placement of the suprapubic catheterization. In case of persistent bleeding after insertion of a suprapubic catheter, the suprapubic catheter should be replaced by one with a balloon blocked and kept under tension for several minutes.

    Full Text Available Objective: To determine the incidence of normal coronaries on cardiac catheterization and its pattern of occurrence according to sex and age. Methods: This is a retrospective study conducted at Queen Alia Heart Institute in Amman-Jordan during the period 2006 to 2011. A total number of 5000 adult patients who had coronary angiography for chest pain, which were reviewed looking for the presence of normal coronaries, its frequency among males and females and its occurrence according to age groups. Results: The overall incidence of normal coronaries on cardiac catheterization was 17.3%, with almost equal ratios for males and females (53.9% and 46.1% respectively. Women in the age group 50 ­ 59 years was the commonest category (33.7% to have normal coronary angiography, whereas the commonest age group for males was 40 to 49 years. Patients above 70 years of age were very less commonly to have normal coronaries (only in 8.5%. Conclusion: Normal coronaries on cardiac catheterization is a recognized finding in both men and women. Recognition of this issue is essential in order to prescribe proper follow up and appropriate medical therapy with correction of modifiable risk factors.

    Full Text Available Background and Objectives: Most patients experience moderate to severe anxiety before cardiac catheterization. This study aimed to investigate the effect of Rosa aromatherapy on anxiety before cardiac catheterization. Methods: In this randomized controlled trial, 60 patients who met the inclusion criteria were conveniently sampled and randomly allocated to the experimental and control groups. Patients in the control group received routine care. In the experimental group, patients received routine care and Rosa aromatherapy for eighteen minutes. The level of anxiety was measured immediately before, and after the treatment. Results: In the stages before and after the study, there were no significant differences between the two groups in the terms of the mean scores of state and total anxiety. However, the mean score of trait anxiety in the experimental group was significantly lower than the control group. Furthermore, there was no significant difference between pre- and post-treatment in both groups. Conclusion: Most of the patients experience moderate to severe anxiety before cardiac catheterization. The findings of this study demonstrate that aromatherapy, as administered in this study, is not beneficial.

    Full Text Available Introduction & Objective: This belief that overfilling the bladder after anterior colporrhaphy might have a negative influence on surgical outcome, causes routine catheterization after operation. This study was done to compare short term (24h with long term (72h catheterization after anterior colporrhaphy.Materials & Methods: This randomized clinical trial was carried out at Kosar Hospital , Qazvin (Iran in 2005-2006. One hundred cases candidating for anterior colporrhaphy , were divided in two equal groups . In the first group foley catheter was removed 24 hours and in the second group 72 hours after the operation. Before removing catheter, urine sample was obtained for culture . After removal and urination, residual volume was determinded. If the volume exceeded 200 ml or retention occured, the catheter would be fixed for more 72 hours. Need for recatheterization, urinary retention, positive urine culture,and hospital stay were surveyed. The data was analyzed using T and Fisher tests.Results: Residual volume exceeding 200 ml and the need for recatheterization occurred in one case (2% in the short term group but in the long term group none of the subjects needed recatheterization (P=1. Retention was not seen. In the both groups, one case (2% had positive urine culture with no statistically significant difference (P=1. Mean hospital stay was short in the first group (P=0.00.Conclusion: Short term catheterization after anterior colporrhaphy does not cause urinary retention and decreases hospital stay.

    Background Sex and neighborhood socioeconomic status (nSES) may independently affect the care and outcomes of acute coronary syndromes (ACS), partly through barriers in timely access to cardiac catheterization. We sought to determine whether sex modifies the association between nSES, and the receipt of cardiac catheterization and mortality following an ACS in a universal healthcare system. Methods and Results We studied 14,012 ACS patients admitted to cardiology services between April 18, 2004 and December 31, 2011 in Southern Alberta, Canada. We used multivariable logistic regression to compare the odds of cardiac catheterization within 2 and 30 days of admission and the odds of 30-day and 1-year mortality for men and women by quintile of neighborhood median household income. Significant relationships between nSES and the receipt of cardiac catheterization and mortality after ACS were detected for women but not men. When examined by nSES, each incremental decrease in neighborhood income quintile for women was associated with a 6% lower odds of receiving cardiac catheterization within 30 days (p=0.01) and a 14% higher odds of 30-day mortality (p=0.03). For men, each decrease in neighborhood income quintile was associated with a 2% lower odds of receiving catheterization within 30 days (p=0.10), and a 5% higher odds of 30-day mortality (p=0.36). Conclusions Associations between nSES and receipt of cardiac catheterization and 30-day mortality were noted for women but not men in a universal healthcare system. Care protocols designed to improve equity of access to care and outcomes are required, especially for low-income women. PMID:24895450

    International Nuclear Information System (INIS)

    Objective: To compare the effect of hyperfractionation radiotherapy combined with hepatic artery catheterization chemotherapy and hepatic artery ligation (group A, 65 patients) with conventional fractionation radiation combined with hepatic artery catheterization chemotherapy and hepatic artery ligation (group B, 65 patients) for unresectable primary liver cancer. Methods: A total to 130 stage II primary liver patients confirmed by pathology and evaluated as unresectable by exploratory laparotomy were divided evenly into group A and group B by the sequence of exploration. The two groups were comparable in age, sex, tumor type and positive fetal protein (AFP). Group A patients were treated by hepatic artery chemotherapy (PDD, 10 mg/day) 6 day a week with hepatic artery ligation followed by hyperfractionation radiotherapy (250 cGy/f, bid) 3 days a week with the scheme alternated weekly. Group B patients were treated by conventional fractionation radiotherapy with the same scheme of chemotherapy as group A. The total dose of PDD and radiotherapy for both groups were 240 mg and 45 Gy. Results: The AFP level was reduced to half in 89.7% of patients in group A and 67.6% in group B. The 1-, 3- and 5-year survival rates were 90.8%, 63.1%, 23.1% for group A and 73.9%, 41.5%, 9.2% for group B, the difference was statistically significant (P 0.05). Conclusions: Hyperfractionation radiotherapy combined with hepatic artery catheterization chemotherapy and hepatic artery ligation is an effective and reasonable therapeutic scheme for unresectable liver cancer. It can effectively relieve symptoms, reduce the tumor, increase second surgical resection rate and prolong the survival. At the same time, the operation is simple and relatively easy

    Background Sedatives and analgesics are often administered to achieve conscious sedation for diagnostic and therapeutic procedures. Appropriate concerns have been raised regarding post procedure delirium related to peri-procedural medication in the elderly. The objective of this study was to investigate the effect of premedication on new onset delirium and procedural care in elderly patients. Methods Patients≥70 years old and scheduled for elective cardiac catheterization were randomly assigned to receive either oral diphenhydramine and diaze-pam (25 mg/5 mg) or no premedication. All patients underwent a mini mental state exam and delirium assessment using confusion assess-ment method prior to the procedure and repeated at 4 h after the procedure and prior to discharge. Patients’ cooperation during the procedure and ease of post-procedure were measured using Visual Analog Scale (VAS). The degree of alertness was assessed immediately on arrival to the floor, and twice hourly afterwards using Observer’s Assessment of Alertness/Sedation Scale (OAA/S). Results A total of 93 patients were enrolled. The mean age was 77 years, and 47 patients received premedication prior to the procedure. None of the patients in either group developed delirium. Patients’ cooperation and the ease of procedure was greater and pain medication requirement less both during and after the procedure in the pre-medicated group (P < 0.05 for both). Nurses reported an improvement with patient management in the pre-medicated group (P=0.08). Conclusions In conclusion, premedication did not cause delirium in elderly patients undergoing cardiac catheterization. The reduced pain medication requirement, perceived procedural ease and post procedure management favors premedication in elderly patients undergoing cardiac catheterization.

A 77-year-old woman underwent an acute evolving type A aortic dissection mimicking acute myocardial infarction. Two pathophysiologic mechanisms are discussed: either thrombosis migrating from a previously treated giant aneurism of proximal left anterior descending or a local arterial complication due to left main stenting. Recognition of these occurrences in the catheterization laboratory is important to look immediately for surgery.

    We present a robust method to register three-dimensional echocardiography (echo) images to magnetic resonance images (MRI) based on anatomical features, which is designed to be used in the registration pipeline for overlaying MRI-derived roadmaps onto two-dimensional live x-ray images during cardiac catheterization procedures. The features used in image registration are the endocardial surface of the left ventricle and the centre line of the descending aorta. The MR-derived left ventricle surface is generated using a fully automated algorithm, and the echo-derived left ventricle surface is produced using a semi-automatic segmentation method provided by the QLab software (Philips Healthcare) that it is routinely used in clinical practice. We test our method on data from six volunteers and four patients. We validated registration accuracy using two methods: the first calculated a root mean square distance error using expert identified anatomical landmarks, and the second method used catheters as landmarks in two clinical electrophysiology procedures. Results show a mean error of 4.1 mm, which is acceptable for our clinical application, and no failed registrations were observed. In addition, our algorithm works on clinical data, is fast and only requires a small amount of manual input, and so it is applicable for use during cardiac catheterization procedures.

    Full Text Available Abstract Background Significant bacteriuria (SBU and urinary tract infections (UTIs are common in patients with spina bifida and neuropathic detrusor sphincter dysfunction. Laboratory agar plated culture is the gold standard to establish SBU. It has the disadvantage of diagnostic and subsequent therapeutic delay. Leukocyte esterase tests (LETs and dip slides proved to be useful in the general populations to exclude SBU and UTI. The aim of this study was to evaluate the reliability of LET and dip slide in children with spina bifida without symptoms of UTI. The reliability in children with asymptomatic SBU was not studied before. Methods In one hundred and twelve children with spina bifida on clean intermittent catheterization LETs and dip slides were compared with laboratory cultures. Both tests and agar plated cultures were performed on catheterized urine samples. The hypothesis was that the home tests are as accurate as laboratory cultures. Results A SBU was found in 45 (40% of the 112 laboratory cultures. A negative LET excluded SBU (negative predictive value 96%, while a positive LET had a positive predictive value of 72%. The false positive rate was 28%. Dip slide determination of bacterial growth had no added value, other than serving as transport medium. Conclusions In spina bifida children, leukocyte esterase testing can be used to exclude significant bacteriuria at home, while dip slide tests have no added value to diagnose or exclude significant bacteriuria.

    The need to bypass to the brachial artery is rare. Over a five-year period, 16 patients had suffered iatrogenic post-catheterization injuries of the upper extremity. We have performed 16 bypasses, in 16 patients, mean age was 65 years (range 47-75), to the brachial artery originating from an artery proximal to the shoulder joint. In all cases, the axillary artery was the donor artery. All bypasses were created by using the cephalic vein with the in situ technique and distal anastomoses were made to a distance-free section of brachial artery. No operative mortality, neurological complications or major upper-extremity amputation was associated with the procedure. Life-long-conduit analysis showed 75% patency in the five-year period. After iatrogenic post-catheterization trauma of arterial system of upper extremity, bypasses from axillary to brachial artery with the cephalic vein with the in situ technique is a safe operation with satisfactory long-term patency.

    Introduction: Central venous catheter placement is an effective alternative vascular access for dialysis in patients with chronic renal failure. The purpose of this study was to evaluate the insertion of central venous catheters for hemodialysis using angiographic techniques in patients with previous multiple catheterizations in terms of efficacy of the procedure and early complications. Materials and methods: Between 2008 and 2010, the vascular access team of our hospital placed 409 central venous catheters in patients with chronic renal failure. The procedure was performed using the Seldinger blind technique. In 18 (4.4%) cases it was impossible to advance the guidewire, and so the patients were transported to the angiography suite. Results: Using the angiographic technique, the guidewire was advanced in order to position the central venous catheter. The latter was inserted into the subclavian vein in 12 (66.6%) cases, into the internal jugular vein in 4 (22.2%) and into the femoral vein in 2 (11.1%) cases. There was only one complicated case with severe arrhythmia in 1 (5.5%) patient. Conclusion: Our results suggest that insertion of central venous catheters using angiographic techniques in hemodialysis patients with previous multiple catheterizations is a safe and effective procedure with few complications and high success rates.

    Full Text Available Bachground & aim: Pulse oximetry and cardiac catheterization are concerned in the treatment of children with congenital heart disease. Diagnosis of arterial oxygen saturation in patients with congenital heart disease (CHD can be used to assess and manage their effecacy. The purpose of this study was to compare pulse oximetry and cardiac catheterizations in treatment manage of children with congenital heart disease. Methods: In the present cross sectional study, 110 patients with cyanic and non syani heart disease were studied undergoing right and left heart catheterization by pulse oximetry of index finger and simultaneously, oxygen saturation was measured by cardiac catheterization. Data were analyzed with SPSS software by using Pearson correlation and linear regression. Results: A significant correlation was seen between arterial oxygen saturation measured by pulse oximetry and arterial oxygen saturation (p<0.0001 as well as heart rate, electrocardiogram and pulse oximetry (p<0.0001 respectively. Furthermore, the presence of cyanosis (p=0.001, digital clubbing of the fingers ((p=0.001, low oxygen saturation in the superior vena cava and right atrium (p=0.002 can reduce the accuracy of pulse oximetry for detection of arterial oxygen saturation. The mean right atrial pressure can effect on accuracy of pulse oximetry to detect heartbeat (p=0.034. Maximum sensitivity and specificity for detection of pulse oximetry oxygen saturation was 88 % and 88 heart rate per minute. Conclusion: Pulse oximetric is a useful tool for estimating the arterial oxygen saturation and heart rate in children with congenital heart disease (CHD and is a non-invasive method in comparison with cardiac catheterization.

    Full Text Available Abstract Background A vaginal fistula is a devastating condition, affecting an estimated 2 million girls and women across Africa and Asia. There are numerous challenges associated with providing fistula repair services in developing countries, including limited availability of operating rooms, equipment, surgeons with specialized skills, and funding from local or international donors to support surgeries and subsequent post-operative care. Finding ways of providing services in a more efficient and cost-effective manner, without compromising surgical outcomes and the overall health of the patient, is paramount. Shortening the duration of urethral catheterization following fistula repair surgery would increase treatment capacity, lower costs of services, and potentially lower risk of healthcare-associated infections among fistula patients. There is a lack of empirical evidence supporting any particular length of time for urethral catheterization following fistula repair surgery. This study will examine whether short-term (7 day urethral catheterization is not worse by more than a minimal relevant difference to longer-term (14 day urethral catheterization in terms of incidence of fistula repair breakdown among women with simple fistula presenting at study sites for fistula repair service. Methods/Design This study is a facility-based, multicenter, non-inferiority randomized controlled trial (RCT comparing the new proposed short-term (7 day urethral catheterization to longer-term (14 day urethral catheterization in terms of predicting fistula repair breakdown. The primary outcome is fistula repair breakdown up to three months following fistula repair surgery as assessed by a urinary dye test. Secondary outcomes will include repair breakdown one week following catheter removal, intermittent catheterization due to urinary retention and the occurrence of septic or febrile episodes, prolonged hospitalization for medical reasons, catheter blockage, and

  10. A preliminary discussion of angiographic anatomy and variations of rabbit hepatic vessels and catheterization methods of hepatic artery

    International Nuclear Information System (INIS)

    Objective: To study the normal angiographic anatomy and variations of rabbit hepatic vessels, and explore the optimal method for hepatic artery catheterization. Methods: 30 rabbits were divided into two groups randomly. Modified surgical method and interventional method were used to catheterize hepatic artery respectively, and followed by angiography to demonstrate the normal anatomy and variations of rabbit celiac artery, hepatic artery and portal vein. Results: The route and distribution of rabbit celiac artery and hepatic artery were very different from human's. The commonly seen variation showed the differences in branching bifurcation of hepatic-gastric artery, with the incidence of 13.3%. The rates of successfully hepatic artery catheterization with surgical and interventional methods were 86.6%(13/15) and 80%(12/15) respectively (P>0.05). The surgical method will not be successful, whenever there's variation. Conclusion: The normal anatomy and variation of rabbit celiac artery and hepatic artery are quite different from human's. Both surgical and interventional catheterizations could be rather successful but possessing advantages and disadvantages of each its own. (authors)

    "Successful" adrenal vein catheterization in primary aldosteronism (PA) is often defined by a ratio of >3:1 of cortisol in the adrenal vein vs the inferior vena cava. Non-use of corticotropin (ACTH) during sampling may increase the apparent failure rate of adrenal vein catheterization due to lower cortisol levels. A retrospective study was performed on all patients with confirmed unilateral PA between June 2005 and August 2011. Adrenal vein sampling (AVS) included simultaneous bilateral baseline samples with repeat sampling 15 minutes after intravenous infusion of 250 μg of Cortrosyn (ACTH-S). Successful catheter placement was judged as adrenal cortisol:IVC cortisol of >3:1, applied to both baseline and ACTH-S samples and lateralization of aldosteronism was judged as normalized aldosterone/cortisol (A/C) ratio >3 times the contralateral A/C ratio. In ACTH-S samples, 94% of right-sided catheterizations were biochemically successful with 100% success on the left. Among baseline samples, only 47% of right- and 44% of left-sided samples met the 3:1 cortisol criteria. However, 95% of apparent "failed" baseline cortisol sets still showed lateralization of A/C ratios that matched the ultimate pathology. Non-ACTH-stimulated samples may be incorrectly judged as failed catheter placement when a 3:1 ratio is used. ACTH-stimulated sampling is the preferred means to confirm catheterization during AVS.

    Full Text Available Introduction: Central venous catheterization (CVC can be an important component of the management of patients with severe sepsis and septic shock. CVC, however, is a time- and resource-intensive procedure associated with serious complications. The effects of the absence of shock or the presence of relative contraindications on undertaking central line placement in septic emergency department (ED patients eligible for early goal-directed therapy (EGDT have not been well described. We sought to determine the association of relative normotension (sustained systolic blood pressure >90 mmHg independent of or in response to an initial crystalloid resuscitation of 20 mL/kg, obesity (body mass index [BMI] ≥30, moderate thrombocytopenia (platelet count <50,000 per μL, and coagulopathy (international normalized ratio ≥2.0 with unattempted CVC in EGDT-eligible patients. Methods: This was a retrospective cohort study of 421 adults who met EGDT criteria in 5 community EDs over a period of 13 months. We compared patients with attempted thoracic (internal jugular or subclavian CVC with those who did not undergo an attempted thoracic line. We also compared patients with any attempted CVC (either thoracic or femoral with those who did not undergo any attempted central line. We used multivariate logistic regression analysis to calculate adjusted odd ratios (AORs. Results: In our study, 364 (86.5% patients underwent attempted thoracic CVC and 57 (13.5% did not. Relative normotension was significantly associated with unattempted thoracic CVC (AOR 2.6 95% confidence interval [CI], 1.6-4.3, as were moderate thrombocytopenia (AOR 3.9; 95% CI, 1.5-10.1 and coagulopathy (AOR 2.7; 95% CI, 1.3-5.6.

    The pulsatile flow of blood in a catheterized blood vessel is analyzed. The flow of blood in vessel is modeled as the flow of two immiscible fluids. The fluid in the core region is characterized as a non-Newtonian viscoelastic fluid satisfying the constitutive equation of an Oldroyd-B fluid. The fluid in the peripheral region is treated as a Newtonian fluid. The catheter inside the vessel is modeled as a rigid tube of very small radius. The resulting differential system for velocity in each region is computed numerically by finite-difference scheme and analytically by Laplace transform. A comparison of numerical solution with Laplace transform solution is carried out. Various physical quantities of interest through the computed velocity are also analyzed. PMID:27548476

    Urinary tract infections (UTIs) are among the most common infectious diseases of humans, with Escherichia coli being responsible for >80% of all cases. Asymptomatic bacteriuria (ABU) occurs when bacteria colonize the urinary tract without causing clinical symptoms and can affect both catheterized...... patients (catheter-associated ABU [CA-ABU]) and noncatheterized patients. Here, we compared the virulence properties of a collection of ABU and CA-ABU nosocomial E. coli isolates in terms of antibiotic resistance, phylogenetic grouping, specific UTI-associated virulence genes, hemagglutination...... with that previously described for the prototype ABU E. coli strain, 83972. This is the first global gene expression analysis of E. coli CA-ABU strains. Overall, our data suggest that nosocomial ABU and CA-ABU E. coli isolates possess similar virulence profiles....

    Abdominal aortic aneurysms (AAAs) are a rare entity in the pediatric population. Children with mycotic (infectious) AAA in particular are at risk of life-threatening rupture due to their rapid expansion coupled with aortic wall thinning and deterioration. Here, we present the case of a 10-month-old infant with prior 2-staged repair for hypoplastic left heart syndrome that was incidentally discovered to have a mycotic AAA on abdominal ultrasound (US) for evaluation of renovascular hypertension. Before the time of evaluation with US, the infant had developed methicillin-resistant Staphylococcus aureus bacteremia 3 days after cardiac catheterization with percutaneous thoracic aortic balloon angioplasty. She had normal aortic contours on contrasted computed tomography scan of the abdomen approximately 2 weeks before the aforementioned US evaluation. This infant subsequently underwent open aneurysmorrhaphy with cryopreserved vein patch angioplasty with resolution of her aneurysmal segment.

    Among patients with unstable angina pectoris, those with crescendo angina seem to be at high risk for death and myocardial infarction. We reviewed the clinical, arteriographic, and hemodynamic findings in 218 consecutive catheterized patients with unstable angina. Unstable angina was defined as ischemic cardiac pain at rest associated with transient ECG changes but no evidence for acute myocardial infarction. Patients were divided into two groups according to the duration of symptoms: 134 patients with crescendo angina (new, or increasing, rest pain with previous ischemic symptoms present for more than three months) and 84 with recent onset angina (symptoms present for less than three months). Compared with patients with recent onset symptoms, patients with crescendo angina had more extensive coronary disease and lower ejection fractions, which may explain their poor prognosis.

    BACKGROUND: Pig islet xenotransplantation has the potential to overcome the shortage of donated human islets for islet cell transplantation in type 1 diabetes. Testing in non-human primate models is necessary before clinical application in humans. Intraportal islet transplantation in monkeys is usually performed by surgical infusion during laparotomy or laparoscopy. In this paper, we describe a new method of percutaneous transhepatic portal catheterization (PTPC) as an alternative to current methods of islet transplantation in rhesus monkeys. METHODS: We performed ultrasound-guided PTPC in five adult rhesus monkeys weighing 7-8 kg, with portal vein catheterization confirmed by digital subtraction angiography. We monitored for complications in the thoracic and abdominal cavity. To evaluate the safety of ultrasound-guided PTPC, we recorded the changes in portal pressure throughout the microbead transplantation procedure. RESULTS:  Ultrasound-guided PTPC and infusion of 16 000 microbeads/kg body weight into the portal vein was successful in all five monkeys. Differences in the hepatobiliary anatomy of rhesus monkeys compared to humans led to a higher initial complication rate. The first monkey died of abdominal hemorrhage 10 hours post-transplantation. The second suffered from a mild pneumothorax but recovered fully after taking only conservative measures. After gaining experience with the first two monkeys, we decreased both the hepatic puncture time and the number of puncture attempts required, with the remaining three monkeys experiencing no complications. Portal pressures initially increased proportional to the number of transplanted microbeads but returned to pre-infusion levels at 30 minutes post-transplantation. The changes in portal pressures occurring during the procedure were not significantly different. CONCLUSIONS: Ultrasound-guided PTPC is an effective, convenient, and minimally invasive method suitable for use in non-human primate models of

    Full Text Available Background: Although some investigations have shown higher rates of successful first attempt and fewer attempts by using ultrasound-guided Internal Jugular Vein (IJV catheterization, arterial puncture is still common.. Objectives: The present study aimed to investigate US-guided catheterization of the right IJV via medial-oblique technique and also compare this technique to short-axis technique in open-heart surgery patients.. Patients and Methods: In this randomized clinical trial, 80 patients referred to cardiac operating room of Namazi hospital, Shiraz, Iran from March to July 2014 were selected using census method. Block randomization with website was also done. Then, the patients were divided into two groups of 40, Short Axis Group (SAG and Medial-Oblique Group (M-OG. For short-axis technique, patient’s head was positioned at zero degree angulation with his trunk. For medial-oblique technique, on the other hand, patient’s head was tilted to left to 45 degrees between the head and trunk. Sex, age, Body Mass Index (BMI, access time, guidewire time, cannulation time, total attempts for catheterization, first, second, and third attempt success, arterial puncture, hematoma, bleeding, and catheter malposition were recorded. The overlap between the carotid artery and IJV in zero- and 45-degree angulation was estimated through ultrasound print. After all, Kolmogorov-Smirnov test was used to assess normal distribution of the data. Then, the data were analyzed through Student’s t-test, Mann-Whitney U test, and chi-square test. P < 0.05 was considered as statistically significant.. Results: The results showed no significant differences between the two groups regarding the duration of different catheterization steps (P = 0.376. In all the cases in both groups, accessing the vein was successful with three attempts or less. There were no clinical complications of catheterization in the two groups.

    Full Text Available Aims: The aim of the study was to measure airway patency objectively during dexmedetomidine sedation under radiographic guidance in spontaneously breathing pediatric patients scheduled for cardiac catheterization procedures. Subjects and Methods: Thirty-five patients in the age group 5-10 years scheduled for cardiac catheterization procedures were enrolled. All study patients were given loading dose of dexmedetomidine at 1 mg/kg/min for 10 min and then maintenance dose of 1.5 mg/kg/h. Radiographic airway patency was assessed at the start of infusion (0 min and after 30 min. Antero-posterior (AP diameters were measured manually at the nasopharyngeal and retroglossal levels. Dynamic change in airway between inspiration and expiration was considered a measure of airway collapsibility. Patients were monitored for hemodynamics, recovery time and complications. Statistical Analysis: Student paired t-test was used for data analysis. P < 0.05 was considered significant. Results: Minimum and maximum AP diameters were compared at 0 and 30 min. Nasopharyngeal level showed significant reduction in the minimum (6.27 ± 1.09 vs. 4.26 ± 1.03, P < 0.0001 and maximum (6.51 ± 1.14 vs. 5.99 ± 1.03, P < 0.0001 diameters. Similarly retroglossal level showed significant reduction in the minimum (6.98 ± 1.09 vs. 5.27 ± 1.15, P < 0.0001 and maximum (7.49 ± 1.22 vs. 6.92 ± 1.12, P < 0.0003 diameters. The degree of collapsibility was greater at 30 min than baseline ( P < 0.0001. There was a significant decrease in heart rate ( P < 0.0001, and the average recovery time was 39.86 ± 12.22 min. Conclusion: Even though airway patency was maintained in all children sedated with dexmedetomidine, there were significant reductions in the upper airway dimensions measured, so all precautions to manage the airway failure should be taken.

  4. Evaluation of radiation doses and dose conversion coefficients for pediatric cardiac catheterization procedures

    International Nuclear Information System (INIS)

    Pediatric cardiac catheterization covers both diagnostic and therapeutic procedures that range from simple to complex and can subject pediatric patients to varying radiation doses. There is limited information on radiation doses delivered by pediatric cardiac catheterization procedures and there is no recommended reference dose levels established yet. The study aims to determine the variation in patient radiation doses in terms of dose area product values and effective doses; determine factors that contribute to high doses to optimize protection; and determine the effective dose conversion coefficient. It is also aimed to provide data to help in the establishment of reference dose levels. A total of 761 pediatric patients belonging to age groups 0, 1, 5 and 10 years who undergo diagnostic and three selected therapeutic procedures at King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia are included in the study. Therapeutic procedures include COA, PDA and pulmonary procedures. Fluoroscopy and cine radiography are used in all procedures. Patient demography (weight, age, gender and height), radiographic technique factors, fluoroscopy and cine time, frame rate, and dose area product values are taken from patients records. Results show that the kVp varies by ± 1 kVp between procedures and by ± 6 kVp between AP and oblique + lateral projection for all procedures. The mA for lateral and oblique is about 40-70% higher than for AP. Effective doses for each procedure are estimated from the DAP values. The mean DAP and effective dose per procedure are analyzed for correlation with patient equivalent cylindrical diameter, weight, fluoroscopy time and number of frames. Initial results show that age group 0 and 1 year old have the highest mean value for effective dose (11.3 and 13.8 mSv respectively) for pulmonary procedure. Pooling all ages for each procedure, the pulmonary and PDA procedures gave the highest mean values for effective dose (10 and 8.2 m

    Full Text Available Internal jugular vein (IJV catheterization is a routine technique in the intensive care unit. Ultrasound (US guided central venous catheter (CVC insertion is now the recommended standard. However, mechanical complications still occur due to non-visualization of the introducer needle tip during US guidance. This may result in arterial or posterior venous wall puncture or pneumothorax. We describe a new technique of (IJV catheterization using US, initially the depth of the IJV from the skin is measured in short-axis and then using real time US long-axis view guidance a marked introducer needle is advanced towards the IJV to the defined depth measured earlier in the short axis and the IJV is identified, assessed and cannulated for the CVC insertion. Our technique is simple and may reduce mechanical complications of US guided CVC insertion.

    Nearly 4 million patient procedures performed annually in US cardiac catheterization laboratories utilize contrast media to achieve vessel opacification. The amount of contrast media used is variable and depends on the complexity of the procedure, the method of contrast delivery as well as the skill-level of the operator. Since the total amount of contrast used for each procedure can have both patient safety and economic implications, it is essential for cardiologists to have the ability to control contrast delivery such that optimal angiographic image quality is achieved using the least amount of contrast. Although the complication rate associated with cardiac catheterization remains low, the most common serious complication, contrast-induced nephropathy (CIN), is associated with poor prognosis and a high mortality rate. Numerous interventional strategies for preventing and reducing the severity of CIN have demonstrated varying degrees of clinical benefit, but none has been shown to reliably prevent this serious complication. To date, the most effective approach for reducing the risk of CIN is to properly hydrate the patient and to minimize the amount of contrast media administered. Automated injection systems are intended for use in virtually all cardiac catheterization procedures and have numerous features which can provide potential advantages over traditional methods. With automated injection technology the operator is able to control and precisely monitor contrast delivery. Additionally, the MEDRAD Avanta Fluid Management Injection System utilizes a sterile contrast reservoir which eliminates the need to discard unused contrast in individual opened containers following each procedure. Considering that an average of 50% of opened contrast media is wasted using manual injection methods, this savings can provide a substantial economic benefit. Automated systems also facilitate the use of smaller (5 French) catheter sizes. Precise flow control and the use of

    Full Text Available Abstract Background The extent to which medical residents are involved in the teaching and supervision of medical procedures is unknown. This study aims to evaluate the teaching and supervision of junior residents in central venous catheterization (CVC by resident-teachers. Methods All PGY-1 internal medicine residents at two Canadian academic institutions were invited to complete a survey on their CVC experience, teaching, and supervision prior to their enrolment in a simulator CVC training curriculum. Results Of the 69 eligible PGY-1 residents, 32 (46% consenting participants were included in the study. There were no significant baseline differences between participants from the two institutions in terms of sex, number of ICU months completed, previous CVC training received, number of CVCs observed and performed. Only 16 participants (50% received any CVC training at baseline. Of those who received any training, 63% were taught only by senior resident-teachers. A total of 81 CVCs were placed by 17 participants. Thirty-two CVCs (45% were supervised by resident-teachers. Conclusions Resident-teachers play a significant role both in the teaching and supervision of CVCs placed by junior residents. Educational efforts should focus on preparing residents for their role in teaching and supervision of procedures.

    Full Text Available Central venous catheterization (CVC is a common procedure performed daily for its outnumbered indications, complication rates range are up to 15%. The previous puncture with a fine needle with the Seldinger technique can reduce even more the possible complications, guaranteeing a high percentage of success. The objective was to determine the number of CVC per puncture with Seldinger technique performed by general surgery residents and identify number and type of mechanical complications, related to the residence year. A descriptive transversal cut study has been carried out, between March and November of 2014. A number of 243 patients were evaluated, observing that 41% of the cases were to measure CVP and hemodynamic monitoring; 76% of the punctures were done by 1º and 2º year residents, presenting only 10% on mechanic complications, most frequently on arterial puncture. In conclusion, previous puncture with needle with the Seldinger technique is safer, more secure, lower cost, and reduces the number of complications, it is a variant puncture under ultrasound guidance.

    Full Text Available Cardiac catheterization laboratories are experiencing phenomenal change, as their volume increases and cases become more complex. In the search for the perfect angiographic result, interventional cardiologists have explored numerous therapeutic complementary devices that are used in the cath labs to facilitate achieving this elusive prize. Unfortunately, these adjunctive interventional devices are lacking in the majority of cath labs all around developing countries including those in Middle East /North Africa region (MENA region. In fact, most of coronary interventions here became restricted to implantation of bare metal stents or drug-eluted stents with or without simple balloon predilatation or post-dilatation. The limited adoption of complementary devices reflects concerns of the high costs for these devices, un-suitability for their re-sterilization, having their own learning curve with compelling continuous need for high level of training.In this review, we will summarize the evidence base concerning most of the important therapeutic complementary cardio-vascular interventional devices and comment on challenges facing the more widespread adoption of their use in MENA region .Hopefully, this objective analysis would help fostering their further growth and penetration into the markets, making them part of daily practice

    To evaluate the usefulness of ultrasonography for diagnosis of portal vein thrombosis (PVT) associated with the umbilical venous catheterization (UVC). We reviewed the abnormal ultrasonography of 54 patients with UVC. We observed echogenic thrombus in the portal vein by ultrasonography which has a 5-10 MHz linear transducer. We evaluated the frequency of PVT, the relationship between PVT and duration of UVC, and the location of catheter tip (Group I (n=41): above the diaphragm, Group II (n=9): between the diaphragm and the liver, Group III (n=4): below the liver), the location of thrombus on US, and the change of PVT on the follow-up ultrasonography. PVT was identified in the 7 neonates (13%) among the 54 neonates with UVC. The frequency of PVT was 5% on group I, 45% on group II and 25% on group III. The 6 cases among the 7 cases(86%) of PVT were localized to the umbilical portion of the left portal vein, and there were completely resolved (n=4) or regressed (n=1) on the follow-up ultrasonography(n=5). Remaining one case of PVT was located in the right, left, and main portal veins with collateral formation, and cavernous transformation occurred on the follow-up. Most PVTs by UVC are localized to the umbilical portion of left portal vein. Ultrasonography is a useful modality to diagnose PVT by UVC.

    Full Text Available Abstract Background Patterns of care for acute myocardial infarction (AMI strongly depend on the availability of on-site cardiac catheterization facilities. Although the management found at hospitals without on-site catheterization does not lead to increased mortality, little it known about its impact on resource utilization and non-fatal outcomes. Methods We identified all patients (n = 35,289 admitted with a first AMI in the province of Quebec between January 1, 1996 and March 31, 1999 using population-based administrative databases. Medical resource utilization and non-fatal and fatal outcomes were compared among patients admitted to hospitals with and without on-site cardiac catheterization facilities. Results Cardiac catheterization and PCI were more frequently performed among patients admitted to hospitals with catheterization facilities. However, non-invasive procedures were not used more frequently at hospitals without catheterization facilities. To the contrary, echocardiography [odds ratio (OR, 2.04; 95% confidence interval (CI, 1.93–2.16] and multi-gated acquisition imaging (OR, 1.24; 95% CI, 1.17–1.32 were used more frequently at hospitals with catheterization, and exercise treadmill testing (OR, 1.02; 95% CI, 0.91–1.15 and Sestamibi/Thallium imaging (OR, 0.93; 95% CI, 0.88–0.98 were used similarly at hospitals with and without catheterization. Use of anti-ischemic medications and frequency of emergency room and physician visits, were similar at both types of institutions. Readmission rates for AMI-related cardiac complications and mortality were also similar [adjusted hazard ratio, recurrent AMI: 1.02, 95% CI, 0.89–1.16; congestive heart failure: 1.02; 95% CI, 0.90–1.15; unstable angina: 0.93; 95% CI, 0.85–1.02; mortality: 0.99; 95% CI, 0.93–1.05].

    The jugular vein catheterism (JVC) is adopted for blood access in patients with acute renal failure, in chronic renal failure and when patients show failure of traditional vascular access. The technique of catheter insertion in the jugular vein is quick and easy. Usually correct catheter positioning, before starting the dialytic procedure, is controlled by chest X-ray or by intra-cavitary electrocardiogram. The aim of this work is to evaluate the feasibility of the real-time ultrasound guidance to control the correct positioning of the catheter instead of the usual chest X-ray control. We have studied 158 patients with JVC insertion before the hemodialytic procedure; 54 patients have undergone both ultrasound and a chest X-ray control while 104 were only submitted to ultrasound control. The ultrasound procedure includes an under xifoid scanning, with a convex 3.5 Mhz drill to evaluate the four heart cavities. When the right atrium is identified a second operator rapidly infuses in the venous catheter 15 ml of physiological solution thus creating a blood turbolence easily observed in real time as a light jet inside the atrium. This turbolence appears to be the main evidence for good catheter positioning and we were able to show the light jet in 156 (98%) patients. All light jet positive patients were submitted to the hemodialytic procedure without any complications during and after dialysis. We concluded that the intraoperative ultrasound control technique is an alternative to the chest X-ray evaluation because it offers the possibility for safe intraoperative immediate control thus reducing the total costs of the procedure.

    To determine the usefulness and safety of radiological placement of a central venous catheter by prospectively comparing the results of interventional radiology and blind surgery. For placement of a central venous catheter, the blind surgical method was used in 78 cases (77 patients), and the interventional radiological method in 56 cases (54 patients). The male to female ratio was 66:68, and the patients' mean age was 48 (range, 18-80) years. A tunneled central venous catheter was used in 74 cases, and a chemoport in 60. We evaluated the success and duration of the procedures, the number of punctures required, and ensuing complications, comparing the results of the two methods. The success rates of the interventional radiological and the blind surgical procedure were 100% and 94.8%, respectively. The duration of central catheterization was 3-395 (mean, 120) day, that of chemoport was 160.9 days, and that of tunneled central venous catheter was 95.1 days. The mean number of punctures of the subclavian vein was 1.2 of interventional radiology, and 2.1 for blind surgery. The mean duration of the interventional radiology and the blind surgical procedure was, respectively, 30 and 40 minutes. The postprocedure complication rate was 27.6% (37 cases). Early complications occurred in nine cases (6.7%): where interventional radiology was used, there was one case of hematoma, and blind surgery gave rise to hematoma (n=2), pneumothorax (n=2), and early deviation of the catheter (n=4). Late complications occurred in 32 cases (23.9%). Interventional radiology involved infection (n=4), venous thrombosis (n=1), catheter displacement (n=2) and catheter obstruction (n=5), while the blind surgical procedure gave rise to infection (n=5), venous thrombosis (n=3), catheter displacement (n=4) and catheter obstruction (n=8). The success rate of interventional radiological placement of a central venous catheter was high and the complication rate was low. In comparison with the blind

    Occupational exposure to scattered radiation and protective equipment was assessed in 4 medical institutions in Kyushu, Japan. The areas where scattered radiation occurred, the scattered radiation dose in the operator's position, fluoroscopy time, the number of cinematography sessions, and annual number of patients were assessed, and the annual scattered radiation dose to the operator was estimated. Approximately 90% of scattered radiation was generated by the subject and the collimator. Measurement of scattered radiation during coronary arteriography yielded a dose of 255-1200 [{mu}Sv/hr.] during fluoroscopy and 3.8-26.7 [{mu}Sv/10 sec.] during radiography. The duration of fluoroscopy for ablation was much longer than during general examinations and PTCA, suggesting a possible contribution to occupational exposure. The data for the past 5 years show no marked change in total number of catheterizations, but the number of ablations has rapidly increased. Ablation requires specific skills, and thus it is frequently performed by only a few staff members, resulting in exposure being concentrated in a few specific persons. The estimated doses of scattered radiation to the eyes and thyroid gland, which are assumed to be the most highly exposed sites, were 116.2 [mSv/year] during fluoroscopy and 8.9 [mSv/year] during radiography, for a total of 125.1 [mSv/year]. This dose is very close to the maximum occupational exposure dose recommended by International Commission on Radiological Protection (ICRP), i.e., 150 [mSv/year]. A protective device that does not impose a burden on the operator or limit the functions of x-ray units was installed on top of the examining table as a measure to reduce the occupational dose. In an experiment using this device the scattered radiation dose during inguinal puncture decreased from 0.8 [mSv/hr.] to 0.02 [mSv/hr.], and the shielding rate was 2.5%. The dose was reduced 97.5%. The authors conclude that radiological personnel must make

    In this paper, we proposed a novel master-slave robotic catheterization system with force feedback for VIS (Vascular Interventional Surgery). The force feedback to the operator on the master side is the key factor to improve the safety during VIS. The developed system used the MR (magneto rheological) fluid to realize force feedback, and it used the developed multidimensional monitoring interface to realize the visualization of force feedback, the developed multidimensional monitoring interface can monitor the motion information of the catheter and contact force between catheter tip or side wall and blood vessel wall, and the motion data of the catheter was collected and generated diagram for reference to surgeon. We have developed a force sensor array to detect the contact force between catheter tip or side wall and blood vessel wall. The force information was detected by the developed contact force sensor array when the catheter contacted with the blood vessel. The force feedback and multidimensional information monitoring interface evaluation experiments were done, the tracking characteristic evaluation experiments were also carried out, the experimental results indicated that the developed novel robotic catheterization system with force feedback and visualization of force feedback is effective for VIS, it can improve the safety during VIS.

  6. Entrance radiation doses during paediatric cardiac catheterizations performed for diagnosis or the treatment of congenital heart disease

    International Nuclear Information System (INIS)

    The purpose of this study was to estimate the radiation exposure of children, during cardiac catheterizations for the diagnosis or treatment of congenital heart disease. Radiation doses were estimated for 45 children aged from 1 d to 13 y old. Thermoluminescent dosemeters (TLDs) were used to estimate the posterior entrance dose (DP), the lateral entrance dose (DLAT), the thyroid dose and the gonads dose. A dose-area product (DAP) meter was also attached externally to the tube of the angiographic system and gave a direct value in mGy cm2 for each procedure. Posterior and lateral entrance dose values during cardiac catheterizations ranged from 1 to 197 mGy and from 1.1 to 250.3 mGy, respectively. Radiation exposure to the thyroid and the gonads ranged from 0.3 to 8.4 mGy to 0.1 and 0.7 mGy, respectively. Finally, the DAP meter values ranged between 360 and 33,200 mGy cm2. Radiation doses measured in this study are comparable with those reported to previous studies. Moreover, strong correlation was found between the DAP values and the entrance radiation dose measured with TLDs. (authors)

    The extracorporeal membrane oxygenation (ECMO) cannula has the potential for obstructing flow to the lower limb, thus causing severe ischemia and possible limb loss. We evaluated the safety and clinical efficacy of percutaneous distal perfusion catheterization in preventing limb ischemia. Between March 2013 and February 2015, 28 patients with distal perfusion catheterization after ECMO were included in this retrospective study. The technical success was evaluated by Doppler ultrasound at the popliteal level after saline injection via distal perfusion catheter. Clinical success was assessed when at least one of the following conditions was met: restoration of continuous peripheral limb oximetry value or presence of distal arterial pulse on Doppler ultrasound evaluation or resolution of early ischemic sign after connecting the catheter with ECMO. Twenty-six patients with early ischemia were successfully cannulated with a distal perfusion catheter (92.8%). Clinical success was achieved in 12/28 (42.8%) patients; 8/10 (80.0%) patients with survival duration exceeding 7 days and 4/18 (22.2%) patients with survival duration less than 7 days, respectively. A percutaneous distal perfusion catheter placement was a feasible tool with safety and efficacy in preventing lower limb ischemia for patients with prolonged common femoral arterial cannulation for ECMO.

    central venous thrombosis. Logistic regressive analysis revealed that high level of homocysteic acid was the important risk factor for central venous thrombosis in HD patients with indwelling catheterization of the internal jugular vein.Conclusions The prevalence of central venous thrombosis in Chinese HD patients with indwelling catheterization of the internal jugular vein is quite high, especially in those patients with diabetes mellitus, malignant tumor, high levels of serum lipoprotein and homocysteic acid. Its clinical symptoms are insidious but dangerous. High level of homocysteic acid may be the important risk factor for central venous thrombosis in Chinese HD patients with indwelling catheterization of the internal jugular vein.

    To determine the efficacy of embolization with super-selective catheterization of the internal iliac arterial branches to treat heavily injured trauma patients with pelvic arterial bleeding. A retrospective analysis was performed using the medical records of 37 patients who underwent trans-arterial embolization for trauma-associated pelvic arterial hemorrhage in a regional trauma center between July 2010 and July 2013. In each patient, hemodynamic stability, embolization level, elapsed time for trans-arterial embolization, clinical outcome and embolization-related complications were evaluated. Comparison of elapsed time, and presence of complication was done according to embolization level. Transarterial embolization was conducted in 37 patients. Hemodynamic stability of each patient was classified into hemodynamic stable (n = 9), and unstable (n = 28). Twenty-nine of 37 patients underwent embolization after super-selective catheterization of more than 2nd order branch of internal iliac artery with a microcatheter, and 8 patients underwent proximal internal iliac artery embolization without super-selective catheterization. The mean elapsed procedure time for super-selective embolization (34.76 ± 20.0 minutes) was not significantly longer than proximal internal iliac artery embolization (33.87 ± 16.73 minutes, p = 0.215). Pelvic arterial embolization with super-selective catheterization is a safe and feasible treatment for heavily injured patients with trauma-associated pelvic arterial bleeding.

    The unsteady flow characteristics of blood are analyzed through a catheterized stenotic artery with post-stenotic dilatation. A rigid tube with a pair of abnormal wall segments in close proximity to each other is employed to geometrically simulate the diseased artery. A micropolar fluid model is used to capture the rheological characteristics of the streaming blood in the annulus. The mild stenosis approximation is employed to derive the governing flow equation which is then solved using a robust finite difference method. Particular attention is paid to the effects of geometrical parameters of the arterial wall and rheological parameters of the blood on axial velocity, flow rate, resistance impedance and wall shear stress. The global behavior of blood is also analyzed through instantaneous pattern of streamlines. PMID:26541601

  13. The primary experimental study of self-made percutaneous catheterized thrombectomy device for acute massive pulmonary embolism

    International Nuclear Information System (INIS)

    Objective: To evaluate efficacy, feasibility and safety of the self-made percutaneous catheterized thrombectomy divice in animal model for thrombus removal. Methods: Seven dogs were selected, with acute massive pulmonary embolism animal models created by injecting thrombi into the pulmonary arterial trunk via percutaneous femoral vein approach. After half an hours the catheter sheath was inserted into the occluded pulmonary artery through right femoral vein in 5 dogs, left femoral vein in 1 dog and right internal jugular vein in another one. The procedure began to remove the thrombi with simultaneous recording the thrombectomy time and the blood volume drainage. Blood gass was tested before and after embolization together with those of thrombi removement, continuously monitored pulmonary arterial pressure and intermittently performed angiography. The mean time form vascular recanalization to euthanasia was 2 hours, and then the lung specimens were resected for histological examination. Results: One animal died of pulmonary arterial penetration during thrombi removal, but others were all alive by the end of the test. Mean time of removing thrombi was 2.4 minutes with mean volume blood drainage of 84 ml. Angiograms showed the approximately complete patency of the pulmonary arterial trunk after reopening of occlusion but still with remnont thrombi within distal branches and arterial pressure with blood gas returned to normal level. Pathology revealed the recanalization of pulmonary arterial trunk but with thromi still staying in the distal branches, and effusion around the arteries. Conclusions: The self-made percutaneous catheterized thrombectomy device is effective, feasible and comparatively safe in the treatment of acute massive pulmonary embolism in this primary test.

    Full Text Available Introduction: Nowadays, assessment of brain oxygen saturation, which is simply appliable and noninvasive method, can provide the anesthesia plans to be optimized according to the needs of the brain, which is the main target organ. Brain may be exposed to hypoxia due to supply-demand imbalance of oxygen not only in general anesthesia procedures but also in sedation practices. The aim of the study is to compare the effects of dexmedetomidine and propofol which are widely used agents for pediatric catheterization procedures on brain oxygen saturation using Fore-Sight. Material and Methods: A total of 44 patients undergoing diagnostic cardiac catheterization between 1 and 18 years old were included in the study. All patients, who were randomly divided into two groups, had ASA physical status I-II. In Group Propofol (Group P, n = 22,induction of sedation was made by midazolam (0.5 mg,iv + propofol (1m/kg,iv, and in Group Dexmedetomidine (Group D, n = 22, induction of sedation was made by midazolam (0.5 mg,iv +dexmedetomidine (1mcg/kg, iv. Throughout the sedation, cerebral tissue oxygen saturation (SctO 2 was recorded by Fore-Sight in addition to routine monitoring. Results: There were no statistically significant differences between the groups in terms of demographic data, hemodynamic data and sedation scores. On other hand, statistically significant decreases in cerebral tissue oxygen saturation were detected especially at 5th and 10th minutes, in Group D, while cerebral oxygenation level did not decrease in Group P. Though, statistically significant difference was determined between two groups in terms of cerebral oxygen saturation, the obtained data was not interpreted as cerebral desaturation. Conclusion: As a conclusion, there was a statistically significant but clinically insignificant decrease in cerebral tissue oxygen saturation in dexmedetomidine group compared to propofol group. Although it does not seem to be important in hemodynamic

Mean age was 35±5 years consisting of 40 females and 12 males. Valve area, Pulmonary artery systolic pressure (PAP, E (Maximum Velocity of mitral valve at the beginning of diastole & Em (Maximum rate of mitral annular motion at the beginning of diastole which is recorded through septal or lateral wall annulus site velocity and left atrial (LA size were also measured by echocardiography and PCWP & PAP through catheterism. All patients had normal ejection fraction (EF and coronary arteries; there was no other valvular diseases and shunts. Results: There was a significant correlation between PAP in echocardiography and catheterism. Mean PAP was 53±19 mmHg in echocardiography and 53.9±17.8mmHg in catheterism. There wasn't any correlation between PCWP in echocardiography and catheterism (P=0.33 and also no relation between PCWP and mitral valve area (MVA or LA size (P=0.2. E/Em ratio increased in severe MS cases.Conclusion: E/Em ratio and suggested formula would overestimate the wedge pressure so echocardiography is not a reliable method for measuring PCWP in severe MS. Em velocity and E/Em ratio may be used for estimating MS severity.

    Ultrasound-guided procedures may be easier to perform when the operator's eye axis, needle puncture site, and ultrasound image display form a straight line in the puncture direction. However, such methods have not been well tested in clinical settings because that arrangement is often impossible due to limited space in the operating room. We developed a wireless remote display system for ultrasound devices using a tablet computer (iPad Mini), which allows easy display of images at nearly any location chosen by the operator. We hypothesized that the in-line layout of ultrasound images provided by this system would allow for secure and quick catheterization of the radial artery. We enrolled first-year medical interns (n = 20) who had no prior experience with ultrasound-guided radial artery catheterization to perform that using a short-axis out-of-plane approach with two different methods. With the conventional method, only the ultrasound machine placed at the side of the head of the patient across the targeted forearm was utilized. With the tablet method, the ultrasound images were displayed on an iPad Mini positioned on the arm in alignment with the operator's eye axis and needle puncture direction. The success rate and time required for catheterization were compared between the two methods. Success rate was significantly higher (100 vs. 70 %, P = 0.02) and catheterization time significantly shorter (28.5 ± 7.5 vs. 68.2 ± 14.3 s, P method as compared to the conventional method. An ergonomic straight arrangement of the image display is crucial for successful and quick completion of ultrasound-guided arterial catheterization. The present remote display system is a practical method for providing such an arrangement.

    Objective To explore the influence of repeatedly PICC catheterized on catheter tip position. Methods We analyzed the catheter tip position of patients who located PICC in one level three class-A hospital in Beijing from May to October in 2014. A total of 381 effective medical records were collected and divided into having the history of catheterization group and having no history of catheterization group depending on patients whether catheterized before. The patients having the history catheterization were divided into ipsilateral catheter group(B1 group)and no ipsilateral catheter group(B0 group),the catheter tip position was compared. Results The best catheter tip position for patients having the history of catheterization was 30. 79% , which was lower than patients having no history group of 52. 66%(χ2 = 17. 565,P < 0. 01),and the patients of having catheterization history group had the incidence rate of shallow catheterization(47. 74% )higher than 35. 40% in the no catheterization history group(χ2 = 5. 817,P < 0. 05). The patients of having catheterization history group happened the incidence of catheter tip position acquired dystopia of venae subclavia higher than patients having no catheterization history group(P < 0. 05). The best catheter tip position had lower rate in the B1 group comparing with B0 group,but the patients acquired dystopia of venae subclavia in the B1 group was lower than the patients in the B0 group(P < 0. 05). Conclusions Multiple PICC catheterization reduces the accuracy of catheter tip position,and impacts the safety and reservation of PICC. We should minimize the non-planned extubation incidences. If patients require re-catheterizaiton,we should select the opposite limbs to catheterize without catheterizaiton contraindication to ensure the safe of PICC catheterization.%目的:探讨多次 PICC 置管对导管尖端位置的影响。方法对2014年5—10月北京市某三级甲等医院肿瘤科 PICC 置管患者的导管尖端

    Accidental subclavian artery cannulation is an uncommon but potentially serious complication of central venous catheterization. Removal of a catheter inadvertently placed in the subclavian artery can lead to substantial bleeding, as achieving hemostasis in this area through manual compression presents considerable difficulty. Additionally, surgical treatment might be unsuitable for high-risk patients due to comorbidities. Here, we report a case of an inadvertently-inserted 11.5-French hemodialysis catheter in the subclavian artery during internal jugular venous catheterization. We performed percutaneous closure of the subclavian artery using three 6-French Perclose Proglide® devices with a balloon tamponade in the proximal part of the subclavian artery. Closure was completed without embolic neurological complications. PMID:27482271

    Paediatric cardiac catheterizations may result in the administration of substantial amounts of iodinated contrast media and ionizing radiation. The aim of this work was to investigate the effect of iodinated contrast media in combination with in vitro and in vivo X-ray radiation on lymphocyte DNA. Six concentrations of iodine (15, 17.5, 30, 35, 45, and 52.5 mg of iodine per mL blood) represented volumes of iodinated contrast media used in the clinical setting. Blood obtained from healthy volunteers was mixed with iodinated contrast media and exposed to radiation doses commonly used in paediatric cardiac catheterizations (0 mGy, 70 mGy, 140 mGy, 250 mGy and 450 mGy). Control samples contained no iodine. For in vivo experimentation, pre and post blood samples were collected from children undergoing cardiac catheterization, receiving iodine concentrations of up to 51 mg of iodine per mL blood and radiation doses of up to 400 mGy. Fluorescence microscopy was performed to assess γH2AX-foci induction, which corresponded to the number of DNA double-strand breaks. The presence of iodine in vitro resulted in significant increases of DNA double-strand breaks beyond that induced by radiation for ≥ 17.5 mg/mL iodine to blood. The in vivo effects of contrast media on children undergoing cardiac catheterization resulted in a 19% increase in DNA double-strand breaks in children receiving an average concentration of 19 mg/mL iodine to blood. A larger investigation is required to provide further information of the potential benefit of lowering the amount of iodinated contrast media received during X-ray radiation investigations.

    Background Isolated pulmonary valve stenosis (PS) makes up 6-9% of all congenital heart defects among children. The initial gold standard for diagnosis, follow-up of PS is by echocardiography. However, the most accurate diagnosis still remains to be measurement of the pressure gradient through transcatheterization. The purpose of this study is to compare the difference between the echocardiographic data to the cardiac catheterization data on the diagnosis, treatment, and follow-up in patients...

  2. Suspension model for blood flow through a catheterized arterial stenosis with peripheral layer of plasma free from cells

    2016-06-01

    The present article describes the blood flow in a catheterized artery with radially symmetric and axially asymmetric stenosis. To understand the effects of red cell concentration, plasma layer thickness and catheter size simultaneously, blood is considered by a two-layered model comprising a core region of suspension of all the erythrocytes (particles) supposed to be a particle-fluid mixture and a peripheral zone of cell-free plasma. The analytical expressions for flow features, such as fluid phase and particle phase velocities, flow rate, wall shear stress and resistive force are obtained. It is witnessed that the presence of the catheter causes a substantial increase in the frictional forces on the walls of arterial stenosis and catheter, shear stress and flow resistance, in addition to that, have occurred due to the presence of red cells concentration (volume fraction density of the particles) and the absence of peripheral plasma layer near the wall of the stenosed artery. The introduction of an axially asymmetric nature of stenosis and plasma layer thickness causes significant reduction in flow resistance. One can notice that the two-phase fluid (suspension model) is more profound to the thickness of peripheral plasma layer and catheter than the single-phase fluid.

    Full Text Available OBJECTIVE Anesthetic management for interventional cardiac procedures/cardiac catheterization in pediatric patients is challenging. Cardiac anomalies vary from simple to complex congenital cardiac anomalies, shunts may be present at multiple levels and patients may be profoundly cyanotic, may be with ventricular dysfunction. They usually require sedation and analgesia to maintain steady stable state. In adults, such type of procedures can be well managed with local anesthesia. METHODS Fifty patients were included in the study. They were randomly divided into two groups- Group A (n=25 patients received femoral N. block along with IV sedation and analgesia while group B (n=25 patients received only IV sedation and analgesia. Both groups were compared for hemodynamics, pain score and requirement of IV anesthetic agents and any complications if come up. RESULTS Group A patients required IV ketamine 3.24mg/kg (±0.31SD as compared to 5.58mg/kg (±1.6SD in group B, which suggests significantly reduced requirement of IV anesthetic agents in group where femoral nerve block has been given. Hemodynamic parameters remained stable and comparable (no statistically significant variation Pain score was less in group A patients than group B. CONCLUSION It has been observed that Group A patients required less dosages of IV anesthetic agents, with stable hemodynamics and less pain score and sedation score as compared to group B patients.

    We present a feasibility study on hybrid echocardiography (echo) and x-ray image guidance for cardiac catheterization procedures. A self-tracked, remotely operated robotic arm with haptic feedback was developed that attached to a standard x-ray table. This was used to safely manipulate a three-dimensional (3D) trans-thoracic echo probe during simultaneous x-ray fluoroscopy and echo acquisitions. By a combination of calibration and tracking of the echo and x-ray systems, it was possible to register the 3D echo images with the 2D x-ray images. Visualization of the combined data was achieved by either overlaying triangulated surfaces extracted from segmented echo data onto the x-ray images or by overlaying volume rendered 3D echo data. Furthermore, in order to overcome the limited field of view of the echo probe, it was possible to create extended field of view (EFOV) 3D echo images by co-registering multiple tracked echo data to generate larger roadmaps for procedure guidance. The registration method was validated using a cross-wire phantom and showed a 2D target registration error of 3.5 mm. The clinical feasibility of the method was demonstrated during two clinical cases for patients undergoing cardiac pacing studies. The EFOV technique was demonstrated using two healthy volunteers.

    The use of checklists is recommended for the assessment of competency in central venous catheterization (CVC) insertion. To explore the use of a global rating scale in the assessment of CVC skills, this study seeks to compare its use with two checklists, within the context of a formative examination using simulation. Video-recorded performances of CVC insertion by 34 first-year medical residents were reviewed by two independent, trained evaluators. Each evaluator used three assessment tools: a ten-item checklist, a 21-item checklist, and a nine-item global rating scale. Exploratory principal component analysis of the global rating scale revealed two factors, accounting for 84.1% of the variance: technical ability and safety. The two checklist scores correlated positively with the weighted factor score on technical ability (0.49 [95% CI 0.17-0.71] for the 10-item checklist; 0.43 [95% CI 0.10-0.67] for the 21-item checklist) and negatively with the weighted factor score on safety (-0.17 [95% CI -0.48-0.18] for the 10-item checklist; -0.13 [95% CI -0.45-0.22] for the 21-item checklist). A checklist score of 80% on both checklists. All these candidates committed serious errors. In conclusion, the practice of universal adoption of checklists as the preferred method of assessment of procedural skills should be questioned. The inclusion of global rating scales should be considered. PMID:21877217

    For wild and domestic felids, electroejaculation (EE) is the most common semen collection method. However, the equipment is expensive, there is a risk of urine contamination and animals usually show strong muscular contraction despite general anesthesia. Accordingly, we tested the feasibility of a different approach using urethral catheterization (UC) in seven African lions, previously described for domestic cats only. After general anesthesia with the α2-agonist medetomidine (which also stimulates semen release into the urethra) and ketamine, a transrectal ultrasound was performed to locate the prostate. A commercial dog urinary catheter (2.6 or 3.3 mm in diameter) was advanced approximately 30 cm into the urethra to allow semen collection into the lumen of the catheter by capillary forces. After retraction, sperm volumes between of 422.86 ± 296.07 μl yielded motility of 88.83 ± 13.27% (mean ± SD) with a mean sperm concentration of 1.94 × 10(9)/ml. Here we describe a simple, field friendly and effective method to attain highly concentrated semen samples with excellent motility in lions and potentially other wild felid species as an alternative to electroejaculation.

    The radial artery (RA) is a commonly used conduit for coronary artery bypass grafting, and recent studies have demonstrated that it provides superior long-term patency rates to the saphenous vein in most situations. In addition, the RA is also being used with increasing frequency as the access point for coronary angiography and percutaneous coronary interventions. However, there has been concern for many years that these transradial procedures may have a detrimental impact on the function of RA grafts used in coronary artery bypass grafting, and there is now comprehensive evidence that such interventions cause morphologic and functional damage to the artery in situ. Despite this, there remain remarkably few studies investigating the use of previously cannulated RAs as grafts in coronary artery bypass surgery, and there are no clear guidelines on the use of the RA in coronary artery bypass grafting after its catheterization. This article will review concisely the evidence that transradial procedures cause damage to the RA, and discuss the impact this could have on previously cannulated RAs used as coronary artery bypass grafting conduits. On the basis of the evidence assessed, we make a number of recommendations to both surgeons and cardiologists regarding use of the RA in cardiovascular procedures. PMID:27572880

    In this study, the influence of patient size on organ and effective dose conversion coefficients (DCCs) was investigated for a representative interventional fluoroscopic procedure-cardiac catheterization. The study was performed using hybrid phantoms representing an underweight, average and overweight American adult male. Reference body sizes were determined using the NHANES III database and parameterized based on standing height and total body mass. Organ and effective dose conversion coefficients were calculated for anterior-posterior, posterior-anterior, left anterior oblique and right anterior oblique projections using the Monte Carlo code MCNPX 2.5.0 with the metric dose area product being used as the normalization factor. Results show body size to have a clear influence on DCCs which increased noticeably when body size decreased. It was also shown that if patient size is neglected when choosing a DCC, the organ and effective dose will be underestimated to an underweight patient and will be overestimated to an underweight patient, with errors as large as 113% for certain projections. Results were further compared with those published for a KTMAN-2 Korean patient-specific tomographic phantom. The published DCCs aligned best with the hybrid phantom which most closely matched in overall body size. These results highlighted the need for and the advantages of phantom-patient matching, and it is recommended that hybrid phantoms be used to create a more diverse library of patient-dependent anthropomorphic phantoms for medical dose reconstruction.

    Background Hemodynamic evaluation is crucial for the management of patients with pulmonary hypertention. Clinicians often prefer a rapid and non-invasive method. This study aimed to examine the feasibility of transthoracic echocardiography for the measurements of hemodynamic parameters in patients with pulmonary hypertension.Methods A prospective single-center study was conducted among 42 patients with pulmonary hypertension caused by different diseases. Transthoracic echocardiography and right-heart catheterization were performed within 24 hours. Pulmonary artery systolic, diastolic and mean pressure (PASP, PADP and PAMP), cardiac output (CO), and pulmonary capillary wedge pressure (PCWP) were measured by both methods. A linear correlation and a Bland-Altman analysis were performed to compare the two groups of hemodynamic parameters.Results A good correlation was found between invasive and non-invasive measurements for PASP (r=0.96), PADP (r=0.85), PAMP (r=0.88), CO (r=0.82), and PCWP (r=0.81). Further agreement analysis done by the Bland-Altman method showed that bias and a 95% confidence interval for PASP, PADP, and CO were clinically acceptable while great discrepancies existed for PAMP and PCWP.Conclusions The non-invasive measurements by PASP, PADP, and CO in patients with pulmonary hypertension correlate well with the invasive determinations. Transthoracic echocardiography (TTE) was inappropriate for estimating PCWP and PAMP.

    Abstract Objective: to compare the incidence of vascular complications in patients undergoing transfemoral cardiac catheterization with a 6F introducer sheath followed by 3-hour versus 5-hour rest. Methods: randomized clinical trial. Subjects in the intervention group (IG) ambulated 3 hours after sheath removal, versus 5 hours in the control group (CG). All patients remained in the catheterization laboratory for 5 hours and were assessed hourly, and were contacted 24, 48, and 72 h after hospital discharge. Results: the sample comprised 367 patients in the IG and 363 in the GC. During cath lab stay, hematoma was the most common complication in both groups, occurring in 12 (3%) IG and 13 (4%) CG subjects (P=0.87). Bleeding occurred in 4 (1%) IG and 6 (2%) CG subjects (P=0.51), and vasovagal reaction in 5 (1.4%) IG and 4 (1.1%) CG subjects (P=0.75). At 24-h, 48-h, and 72-h bruising was the most commonly reported complication in both groups. None of the comparisons revealed any significant between-group differences. Conclusion: the results of this trial show that reducing bed rest time to 3 hours after elective cardiac catheterization is safe and does not increase complications as compared with a 5-hour rest.

    To assess feasibility of proper hepatic artery catheterization using a 3D model obtained from preprocedural computed tomographic angiography (CTA), fused with real-time fluoroscopy, during transarterial chemoembolization of hepatocellular carcinoma. Twenty consecutive cirrhotic patients with hepatocellular carcinoma undergoing transarterial chemoembolization were prospectively enrolled onto the study. The early arterial phase axial images of the preprocedural CTA were postprocessed on an independent workstation connected to the angiographic system (Innova 4100; GE Healthcare, Milwaukee, WI), obtaining a 3D volume rendering image (VR) that included abdominal aorta, splanchnic arteries, and first and second lumbar vertebrae. The VR image was manually registered to the real-time X-ray fluoroscopy, with the lumbar spine used as the reference. The VR image was then used as guidance to selectively catheterize the proper hepatic artery. The procedure was considered successful when performed with no need for intraarterial contrast injections or angiographic acquisitions. The procedure was successful in 19 (95 %) of 20 patients. In one patient, celiac trunk angiography was required for the presence of a significant ostial stenosis that was underestimated at computed tomography. Time for image reconstruction and registration was <10 min in all cases. The use of preprocedural CTA model with fluoroscopy enables confident and direct catheterization of the proper hepatic artery with no need for preliminary celiac trunk angiography, thus reducing radiation exposure and contrast media administration.

    Full Text Available La punción percutánea de la arteria radial para la realización de procedimientos por cateterismo ha ganado aceptación debido a una eficacia similar a la obtenida con el acceso femoral. En el presente trabajo evaluamos los resultados obtenidos con la punción repetida de esta arteria. En un total de 182 accesos radiales se realizaron 17 punciones repetidas, y mediante ellas, 20 procedimientos (9 coronariografías y 11 angioplastias. Se obtuvo éxito del acceso en 15 punciones repetidas (88.2% y éxito del procedimiento en todos los casos cuando logramos éxito del acceso. Si bien el grupo es pequeño es suficiente para mostrar que la punción repetida de la arteria radial es factible y permite una alta tasa de éxito de los procedimientos con una disminución ostensible de las complicaciones locales.The radial artery approach for percutaneous cardiac interventions has gained worldwide acceptance due to the similar results obtained by the femoral artery access. In this paper, we report our experience with repeated puncture of the radial artery. One hundred and eighty two radial artery access procedures were performed, in 17 interventions the puncture was repeated once or twice, with a total of 20 therapeutic catheterizations (9 coronary angiographies, 11 angioplasties. There was no therapeutic failure through the radial approach but, we successfully gained access in 88.2% (15/17 of the re-interventions cases. Although an experience with a low number of cases, we had a very high successful therapeutic rate, and also a remarkable lowering of local complications, this shows the feasibility and potential of this technique.

    Full Text Available PURPOSE: To determine adherence rate and variables associate with patients' adherence to Clean Intermittent Self Catheterization (CISC. MATERIALS AND METHODS: Patients refereed to CISC training program between July 2006 and May 2008, were prospectively evaluated with urodynamic, 3 days bladder diary (BD and WHOQoL-bref questionnaire. After training to perform CISC, patients were evaluated at 2 weeks, monthly for 6 months and at 12 months with clinical visits and BD. Patients were considered adherent if they were performing at least 80% of the initial recommendation. RESULTS: Sixty patients (50.4 ± 19.9 years old were trained to perform CISC (21 female and 39 male. Out of them, 30 (50% had neurogenic and 30 (50% had a non-neurogenic voiding dysfunction. The adherence rate at 6 and 12 months was 61.7%, 58%, respectively. Patients < 40 years old had adherence rate of 86%. Women and neurogenic patients had higher adherence rate than their counterparts (p = 0.024 and p = 0.016, respectively. In the WHOQoL-bref, patients that adhere to the program had a significant higher score on psychological and social relationships domains. There was not difference in pre and post training WHOQoL-bref scores. Educational background, marriage status, detrusor leak point pressure, Bladder Capacity, number of leakage episodes did not play a role on the adherence rate. CONCLUSION: Patients in CISC program present a reasonable adherence after one year. Women, neurogenic voiding dysfunction and patients under 40 years old were significantly more adherents. The psychological and social relationship status seems to positively interfere on adherence. CISC did not affect patient's QoL evaluated by WHOQoL-bref.

    Objective: To study the correlation of low-dose 64-row multi-detector computed tomography (MDCT) with echocardiography and cardiac catheterization angiography (CCA) in the assessment of pulmonary arterial anatomy in children with cyanotic congenital heart disease (CCHD). Materials and methods: This prospective study included 105 children (74 males, 31 females) with CCHD, in the age group of 2 months to 20 years, who underwent 64-row MDCT examination (low-dose CT protocol), echocardiography and CCA for the assessment of pulmonary arteries, including visualization, presence of confluence, stenosis and collaterals. Statistical analysis was performed using the non-parametric statistical analysis test to evaluate the concordance or discordance between echocardiography, MDCT and CCA. Results: 64-row MDCT detected significantly more main and branch pulmonary arteries, patent pulmonary confluences, and more cases of pulmonary artery stenosis. CCA detected more major aorto-pulmonary collaterals than MDCT, whereas echocardiography failed to identify these major aorto-pulmonary collaterals. The effective CT radiation dose to patients less than 2 years of age was in the range of 0.7–2.5 mSv, where as the dose in patients more than 2 years of age ranged from that of 2.1 to 4.2 mSv, which is much less than the radiation dose reported in cardiac catheterization angiography. Conclusion: In cases where cardiac MRI cannot be performed, or is not sufficiently informative, low-dose 64-row MDCT correlates well with CCA and can provide adequate information about pulmonary arterial anatomy in children with cyanotic congenital heart disease, and can replace invasive cardiac catheterization angiography with markedly reduced radiation dosage to the patient.

    Cardiac output during right-sided heart catheterization is an important variable for patient selection of advanced therapies (cardiac transplantation and left ventricular assist device implantation). The Fick method to determine cardiac output is commonly used and typically uses estimated oxygen consumption (VO2) from 1 of 3 published empirical formulas. However, these estimation equations have not been validated in patients with heart failure and reduced ejection fraction (HFrEF). The objectives of the present study were to determine the accuracy of 3 equations for estimating VO2 compared with direct measurement of VO2 and determine the extent clinically significant error occurred in calculating cardiac output of patients with HFrEF. Breath-by-breath measurements of VO2 from 44 patients who underwent cardiac catheterization (66% men; age, 65 ± 11 years, left ventricular ejection fraction, 22 ± 6%) were compared with the derived estimations of LaFarge and Miettinen, Dehmer et al, and Bergstra et al. Single-sample t tests found only the mean difference between the estimation of LaFarge and Miettinen and the measured VO2 to be nonsignificant (-10.3 ml/min ± 6.2 SE, p = 0.053). Bland-Altman plots demonstrated unacceptably large limits of agreement for all equations. The rate of ≥25% error in the equations by LaFarge and Miettinen, Dehmer et al, and Bergstra et al occurred in 11%, 23%, and 45% of patients, respectively. Misclassification of cardiac index derived from each equation for 2 clinically important classifications: cardiogenic shock-21%, 23%, and 32% and hypoperfusion-16%, 16%, and 25%; respectively. In conclusion, these findings do not support the use of these empiric formulas to estimate the VO2 at rest in patients with HFrEF who underwent right-sided heart catheterization.

    Left atrium and/or left ventricle dilatation on echocardiography is considered to be an indication for closure of ventricular septal defects (VSD). No study has addressed the accuracy of using dilated left heart chambers when defining significant left-to-right shunting quantified by cardiac catheterization in isolated small or moderate VSDs. In this study, the relation between dilated left heart chambers, measured by echocardiography, and left-to-right ventricle shunting, quantified by cardiac catheterization, was evaluated in patients with isolated VSD. The medical records of all patients with isolated VSD who had undergone catheterization from 1996 to 2010 were examined retrospectively. Normative data for left heart chambers adjusted for body weight (BW) and body surface area (BSA) were used. The pulmonary-to-systemic flow ratio (Qp:Qs) was calculated by an oximetry technique. A total of 115 patients (mean age 7.3 ± 5 years) fulfilled the inclusion criteria. There was a statistically significant difference in terms of Qp:Qs between the patient groups with normal and dilated left heart chambers, when adjusted for BW and BSA (p = 0.001 and p = 0.002, respectively). But the relationships between Qp:Qs and left heart chamber sizes on echocardiography were not strong enough to be useful for making surgical decisions, as left heart chamber dilatation was not significantly associated with Qp:Qs ≥ 2 (p = 0.349 when adjusted for BW, p = 0.107 when adjusted for BSA). Left heart chamber dilatation was significantly associated with Qp:Qs ≥ 1.5 only when it was adjusted for BSA (for BW p = 0.022, for BSA p = 0.006). As a result, left heart chamber dilatation measured by echocardiography does not show significant left-to-right ventricle shunting, as quantified by catheterization. We still advocate that catheter angiography should be undertaken when left heart chambers are dilated in echocardiography in order to make decisions about closing small- to moderate-sized VSD.

    Sequential sampling from animals challenged with highly pathogenic organisms, such as haemorrhagic fever viruses, is required for many pharmaceutical studies. Using the guinea pig model of Ebola virus infection, a catheterized system was used which had the benefits of allowing repeated sampling of the same cohort of animals, and also a reduction in the use of sharps at high biological containment. Levels of a PS-targeting antibody (Bavituximab) were measured in Ebola-infected animals and uninfected controls. Data showed that the pharmacokinetics were similar in both groups, therefore Ebola virus infection did not have an observable effect on the half-life of the antibody.

    Full Text Available Medication errors are the most common cause of iatrogenic adverse events. They can lead to severe complications, including prolonged hospitalization, unnecessary diagnostic tests and treatments, and even death. Objective:We set to explore the impact of introducing standardized cath lab order forms on medication errors, quality of patient care and staff satisfaction. This was a single center observational study conducted in a tertiary cardiac center in Saudi Arabia. We enrolled a total of 100 consecutive patients who underwent diagnostic or interventional cardiac catheterization before or after the introduction of standardized order forms. The cohort was divided into two equal groups. We compared medication prescription errors (as defined by hospital formulary between the two groups. We also studies the impact of the standardized order forms on peri-procedural care including laboratory tests order completion, peri-procedural fluid and diabetes management, anticoagulant, diuretic and analgesia management. We have also employed a structured questionnaire to assess staff satisfaction with the use of these forms implementation of standardized order forms resulted in significant reduction of prescription errors from 32.0% to 0.0% (p = 0.025. There was also a significant improvement in patient care as indicated by improvement in the rates of completion of laboratory orders that improved from 76.0% to 96.0% after the implementation of order forms (p = 0.004, proper fluid management (100% vs. 86.0%, p = 0.023 and better peri-procedural diabetic management (see attached table. There was also improvement in the monitoring of the vascular access site (80% vs. 100%, p = 0.004 that resulted in reduction in access site related complications (6% vs. 0%. We administered a satisfaction questionnaire to 61 participants (nurses, physicians and pharmacists. The mean total satisfaction score was 62.8 for pharmacists, 50.4 for nurses and 48.6 for physicians

Urinary liver-type fatty acid binding protein (L-FABP increases along with tubular hypoxia and may be a detector of systemic circulation injury. The aim of this study was to evaluate the clinical usefulness of detecting increases in urinary L-FABP levels due to administration of CM, as a prognostic biomarker for cardiovascular disease in patients without occurrence of CM-induced nephropathy undergoing cardiac catheterization procedure (CCP. Methods: Retrospective longitudinal analyses of the relationship between urinary L-FABP levels and occurrence of cardiovascular events were performed (n=29. Urinary L-FABP was measured by ELISA before CCP, and at 6, 12, 24, and 48 hours after CCP. Results: Urinary L-FABP levels were significantly higher at 12 hours (P<0.05 and 24 hours (P<0.005 after CCP compared with before CCP, only in the patients with occurrence of cardiovascular events (n=17, but not in those without cardiovascular events (n=12. The parameter with the largest area under the curve (0.816 for predicting the occurrence of cardiovascular events was the change in urinary L-FABP at 24 hours after CCP. The difference in urinary L-FABP levels (ΔL-FABP ≥11.0 µg/g creatinine between before CCP and at 24 hours after CCP was a risk factor for the occurrence of cardiovascular events (hazard ratio, 4.93; 95% confidence interval, 1.27–19.13; P=0.021. Conclusion: Measurement of urinary L-FABP before CCP and at 24 hours after CCP in patients with mild to moderate renal dysfunction may be an important indicator for risk

    The aim of this study was to evaluate the influence that different protocols of urethral catheterization after pharmacological induction (Ur.Ca.P.I.) may have on the semen quality of the domestic cat. The study has been divided into two experiments: one in which different dosages of medetomidine administrated are evaluated and the second one in which the timing of the catheterization after pharmacological induction is tested. In the first experiment, 18 cats were sedated with the recommended dosage of medetomidine (130 μg/kg i.m.) while the other 18 were sedated with a lower dose of the same drug (50 μg/kg i.m.). In the second experiment, three groups were implemented, each containing 25 subjects. In group 1, the semen collection was performed immediately once the pharmacological effect of the drug was reached; in group 2, the semen collection was performed three times every 5 min after the pharmacological effect was reached; finally, in group 3, Ur.Ca.P.I. was performed 20 min after the pharmacological effect was reached. All the different protocols permitted sperm collection, nevertheless the first experiment showed a better quality in terms of volume, concentration, total number of spermatozoa (p sedation with 130 μg/kg of medetomidine leads to a better quality sperm collection than 50 μg/kg does.

    Mercy, a 4 state health system, conducted an FDA-sponsored demonstration whereby prototype unique device identifiers (UDIs) of coronary stents were implemented in its electronic information systems for safety surveillance and research. To accomplish this, a multi-disciplinary team implemented a point of use barcode scanning inventory management system in all 5 Mercy cardiac catheterization laboratories. The system's potential for improving inventory management and tracking Cath Lab supplies was felt to be sufficiently compelling for system deployment outside of the context of the demonstration. Further, it was felt to be useful for all Cath Lab renewable supplies and not just coronary stents. Benefits included preventing procedure delays, lowering costs, and increasing revenue. Finally, the system is extensible to all implanted medical devices and generalizable to most hospitals. PMID:27343161

    Children diagnosed with congenital heart disease often undergo cardiac catheterization for their treatment, which involves the use of ionizing radiation and therefore a risk of radiation-induced cancer. The purpose of this study was to calculate the effective and equivalent organ doses (H{sub T}) in those children and estimate the risk of exposure-induced death. Fifty-three children were divided into three groups: atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA). In all procedures, the exposure conditions and the dose-area product meters readings were recorded for each individual acquisition. Monte Carlo simulations were run using the PCXMC 2.0 code and mathematical phantoms simulating a child's anatomy. The H{sub T} values to all irradiated organs and the resulting E and risk of exposure-induced death values were calculated. The average dose-area product values were, respectively, 40 {+-} 12 Gy.cm{sup 2} for the ASD, 17.5 {+-} 0.7 Gy.cm{sup 2} for the VSD and 9.5 {+-} 1 Gy.cm{sup 2} for the PDA group. The average E values were 40 {+-} 12, 22 {+-} 2.5 and 17 {+-} 3.6 mSv for ASD, VSD and PDA groups, respectively. The respective estimated risk of exposure-induced death values per procedure were 0.109, 0.106 and 0.067%. Cardiac catheterizations in children involve a considerable risk for radiation-induced cancer that has to be further reduced. (orig.)

    To assess the incidence of and risk factors for acute adverse drug reactions (ADRs) (occurring within 1 h) following iopromide administration in cardiac catheterization in Chinese 'real-world' practice. Acute ADRs following iopromide administration during coronary angiography or percutaneous coronary intervention (PCI) have not been systematically evaluated in China. TRUST was a prospective, multicenter, observational study conducted at 63 centers in China. Patients received iopromide (300 or 370 mgI/mL) during coronary angiography or PCI (n = 17,513). Acute ADRs occurred in 66 patients (0.38%); ADRs were mild in 58 patients (0.33%) and severe in two patients (0.01%). Most acute ADRs manifested as allergy-like symptoms such as nausea/vomiting [39 patients (0.22%)] and/or rash [15 patients (0.09%)]. The rate of acute ADRs was lower among patients who received premedication (6/3349; 0.18 %) than those who did not (60/14,164; 0.42%; p = 0.0379), and among those who did receive pre-procedural hydration (10/7993; 0.13%) compared with those who did not (56/9520; 0.59%; p contrast media increased the risk of ADRs, while premedication with corticosteroids, pre-procedural hydration and contrast volume Contrast quality was rated as 'Excellent' in 99.1% of patients. The incidence of acute ADRs was very low with iopromide in cardiac catheterization in China. The risk of acute ADRs increased in patients contrast media. Premedication with corticosteroids and pre-procedural hydration may prevent acute ADRs in at-risk patients. PMID:26058857

    Background The relationship between traffic-related air pollution (TRAP) and risk factors for cardiovascular disease needs to be better understood in order to address the adverse impact of air pollution on human health. Objective We examined associations between roadway proximity and traffic exposure zones, as markers of TRAP exposure, and metabolic biomarkers for cardiovascular disease risk in a cohort of patients undergoing cardiac catheterization. Methods We performed a cross-sectional study of 2,124 individuals residing in North Carolina (USA). Roadway proximity was assessed via distance to primary and secondary roadways, and we used residence in traffic exposure zones (TEZs) as a proxy for TRAP. Two categories of metabolic outcomes were studied: measures associated with glucose control, and measures associated with lipid metabolism. Statistical models were adjusted for race, sex, smoking, body mass index, and socioeconomic status (SES). Results An interquartile-range (990 m) decrease in distance to roadways was associated with higher fasting plasma glucose (β = 2.17 mg/dL; 95% CI: –0.24, 4.59), and the association appeared to be limited to women (β = 5.16 mg/dL; 95% CI: 1.48, 8.84 compared with β = 0.14 mg/dL; 95% CI: –3.04, 3.33 in men). Residence in TEZ 5 (high-speed traffic) and TEZ 6 (stop-and-go traffic), the two traffic zones assumed to have the highest levels of TRAP, was positively associated with high-density lipoprotein cholesterol (HDL-C; β = 8.36; 95% CI: –0.15, 16.9 and β = 5.98; 95% CI: –3.96, 15.9, for TEZ 5 and 6, respectively). Conclusion Proxy measures of TRAP exposure were associated with intermediate metabolic traits associated with cardiovascular disease, including fasting plasma glucose and possibly HDL-C.

    In the United States alone, there are currently approximately 14.5 million cancer survivors, and this number is expected to increase to 20 million by 2020. Cancer therapies can cause significant injury to the vasculature, resulting in angina, acute coronary syndromes (ACS), stroke, critical limb ischemia, arrhythmias, and heart failure, independently from the direct myocardial or pericardial damage from the malignancy itself. Consequently, the need for invasive evaluation and management in the cardiac catheterization laboratory (CCL) for such patients has been increasing. In recognition of the need for a document on special considerations for cancer patients in the CCL, the Society for Cardiovascular Angiography and Interventions (SCAI) commissioned a consensus group to provide recommendations based on the published medical literature and on the expertise of operators with accumulated experience in the cardiac catheterization of cancer patients.

    One of the most treatable causes of lower back pain and associated sciatica is lumbar disc herniation (LDH), which is characterized by rupture of the hard outer wall (annulus fibrosis) in a lumbar intervertebral disc. In the current study, we aimed to: (1) develop and characterize a rat model of sciatica induced by LDH, while introducing a novel method of epidural catheterization; (2) use this model to evaluate the effect of osthole on pain due to LDH, and (3) gain insight into the mechanisms through which osthole affects sciatica induced by LDH. The results indicate that our newly developed rat model maintained mechanical allodynia for 28 days without reduction. Moreover, cyclooxygenase-2 (COX-2) and nitric oxide synthase (NOS) were overexpressed in the associated inflammatory response, which is consistent with clinical manifestations of the disease. We then used this model to study the effect and mechanisms through which osthole affected pain due to LDH. Our study suggests that osthole is capable of reversing hyperalgesia due to LDH, potentially through modulation of activity of COX-2 and NOS, two important proteins for the exacerbation of pain due to LDH. Finally, a molecular modeling simulation showed that osthole has unique binding capabilities to both NOS and COX-2. As the model-induced mechanical hyperalgesia response was consistent, and the position of the catheter tip and the extension/spreading of the drug in the epidural space were reliable, this study developed an improved model to study remedies for sciatic pain. Moreover, our studies demonstrate that osthole may be a feasible treatment for the reduction of pain due to hyperalgesia. PMID:23018204

    Full Text Available Introduction: We aimed to develop a classification method to discriminate ventricular septal defect and atrial septal defect by using severalhemodynamic parameters.Patients and Methods: Forty three patients (30 atrial septal defect, 13 ventricular septal defect; 26 female, 17 male with documentedhemodynamic parameters via cardiac catheterization are included to study. Such parameters as blood pressure values of different areas,gender, age and Qp/Qs ratios are used for classification. Parameters, we used in classification are determined by divergence analysismethod. Those parameters are; i pulmonary artery diastolic pressure, ii Qp/Qs ratio, iii right atrium pressure, iv age, v pulmonary arterysystolic pressure, vi left ventricular sistolic pressure, vii aorta mean pressure, viii left ventricular diastolic pressure, ix aorta diastolicpressure, x aorta systolic pressure. Those parameters detected from our study population, are uploaded to multi-layered artificial neuralnetwork and the network was trained by genetic algorithm.Results: Trained cluster consists of 14 factors (7 atrial septal defect and 7 ventricular septal defect. Overall success ratio is 79.2%, andwith a proper instruction of artificial neural network this ratio increases up to 89%.Conclusion: Parameters, belonging to artificial neural network, which are needed to be detected by the investigator in classical methods,can easily be detected with the help of genetic algorithms. During the instruction of artificial neural network by genetic algorithms, boththe topology of network and factors of network can be determined. During the test stage, elements, not included in instruction cluster, areassumed as in test cluster, and as a result of this study, we observed that multi-layered artificial neural network can be instructed properly,and neural network is a successful method for aimed classification.

    Background Primary percutaneous coronary intervention (PCI) has been clearly identified as the first therapeutic option for patients with acute ST-segment elevation myocardial infarction (STEMI). The importance of reducing door-to-balloon (D2B) time has gained increased recognition. This study aimed to assess the feasibility, safety and efficacy of the strategy of direct ambulance transportation of patients with acute STEMI to catheterization lab to receive primary PCI.Methods The study population included 141 consecutive patients with chest pain and ST-segment elevation who were admitted to the catheterization laboratory directly by the ambulance and underwent primary PCI (DIRECT group).Another 145 patients with STEMI randomly selected from the PCI database, were served as control group (conventional group); they were transported to catheterization laboratory from emergency room (ER). The primary endpoint of D2B time,and secondary endpoint of in-hospital and 30-day major adverse cardiac events (MACE, including death, non-fatal reinfarction, and target vessel revascularization) were compared.Results Baseline and procedural characteristics between the two groups were comparable, except more patients in the DIRECT group presented TIMI 0-1 flow in culprit vessel at initial angiogram (80.1% and 73.8%, P=0.04). Comparing to conventional group, the primary endpoint of D2B time was reduced ((54±18) minutes and (112±55) minutes, P <0.0001)and the percentage of patients with D2B <90 minutes was increased in the DIRECT group (96.9% and 27.0%, P<0.0001).The success rate of primary PCI with stent implantation with final Thrombolysis in Myocardial Infarction (TIMI) 3 flow was significantly higher in the DIRECT group (93.8% and 85.2%, P=0.03). Although no significant difference was found at 30-day MACE free survival rate between the two groups (95.0% and 89.0%, P=0.06), a trend in improving survival status in the DIRECT group was demonstrated by Kaplan-Meier analysis

    Background: Right ventricular function predicts outcome in patients with pulmonary hypertension (PH). Therefore accurate assessment of right ventricular function is essential to graduate severity, assess follow-up, and response to therapy. Purpose: To evaluate whether PH severity could be assessed using electrocardiography-gated CT (ECG-gated CT) functional parameters. A further objective was to evaluate cardiac output (CO) using two ECG-gated CT methods: the reference Simpson technique and the fully automatic technique generated by commercially available cardiac software. Material and Methods: Our institutional review board approved this study; patient consent was not required. Twenty-seven patients who had undergone ECG-gated CT and right heart catheterization (RHC) were included. Two independent observers measured pulmonary artery (PA) diameter, PA distensibility, aorta diameter, right ventricular cardiac output (CT-RVCO) and right ventricular ejection fraction (CT-RVEF) with automatic and Simpson techniques on ECG-gated CT. RHC-CO and mean pulmonary arterial pressure (mPAP) were measured on RHC. Relationship between ECG-gated CT and RHC measurements was tested with linear regression analysis. Results: Inter-observer agreement was good for all measurements (r > 0.7) except for CT-RVCO calculated with Simpson's technique (r = 0.63). Pulmonary artery (PA) distensibility was significantly correlated to mPAP (r = -0.426, P = 0.027). CT-RVEF was correlated with mPAP only when issued from Simpson technique (r = -0.417, P = 0.034). CT-RVEF was not significantly correlated to RHC-CO (P > 0.2). CT-RVCO measured with Simpson technique (r = 0.487, P = 0.010) and automatic segmentation (r = 0.549, P 0.005) correlated equally with RHC-CO. Conclusion: CT-RVEF and CT-RVCO measured on ECG-gated CT are significantly correlated, respectively, to mPAP and RHC-CO in this population with severe reduction of the right ventricular ejection fraction and could be useful for

    Purpose: until now, no mechanical closure devices were available to achieve fast and secure hemostasis for vessel closure after catheterization of small arterial vessels. Material and methods: eighty patients were randomized to evaluate the effect on hemostasis by use of a chitosan pad (Chito-Seal, Abbott Vascular Devices, Galway/Ireland) in comparison to manual compression after diagnostic transbrachial arterial catheterization. Hemostasis after three minutes and one hour as well as local development of a hematoma after one and twenty-four hours were assessed. Results: the use of chitosan pads significantly decreased the bleeding time in the first three minutes after manual compression time (p < 0.01). Significant decrease in bleeding risk at three minutes by use of the chitosan closure pads was also found in subgroups of patients with hypertension (p < 0.001) or diabetes (p < 0.01) and also in patients under anticoagulation therapy (p < 0.01). In addition, long-term protection from bleeding complications such as the risk of hematoma was decreased by the use of chitosan closure pads one hour (p < 0.01) or twenty-four hours (p < 0.001) after catheter removal. Conclusion: the use of an intravascular anchor or suture system is not safely applicable in these vessels due to the small diameter of the brachial artery. Our results document a significant improvement in hemostasis by using chitosan pads in these cases. (orig.)

    Purpose: To compare the success and immediate complication rates of the anatomical landmark method (group 1) and the radiologically (combined real-time ultrasound and fluoroscopy) guided technique (group 2) in the placement of central venous catheters in emergent hemodialysis patients. Material and Methods: The study was performed prospectively in a randomized manner. The success and immediate complication rates of radiologically guided placement of central venous access catheters through the internal jugular vein (n = 40) were compared with those of the anatomical landmark method (n 40). The success of placement, the complications, the number of passes required, and whether a single or double-wall puncture occurred were also noted and compared. Results: The groups were comparable in age and sex. The indication for catheter placement was hemodialysis access in all patients. Catheter placement was successful in all patients in group 2 and unsuccessful in 1 (2.5%) patient in group 1. All catheters functioned adequately and immediately after the placement (0% initial failure rate) in group 2, but 3 catheters (7.5% initial failure rate) were non-functional just after placement in group 1. The total number of needle passes, double venous wall puncture, and complication rate were significantly lower in group 2. Conclusion: Percutaneous central venous catheterization via the internal jugular vein can be performed by interventional radiologists with better technical success rates and lower immediate complications. In conclusion, central venous catheterization for emergent dialysis should be performed under both real-time ultrasound and fluoroscopic guidance.

    The Ovation Stent Graft System is a new trimodular endoprosthesis for the treatment of abdominal aortic aneurysms. A long nitinol stent with anchors serves the suprarenal fixation, whereas inflatable rings in the main body achieve sealing. This dissociation precludes the presence of a nitinol skeleton in the endograft, thus, avoiding competing for the same space within the delivery system, enabling the latter to achieve ultra-low profiles. However, the lack of nitinol support may render the endograft's docking limb prone to collapse in cases of narrow aortoiliac anatomy. We present a case of challenging contralateral limb catheterization, facilitated effectively through the brachial access. Preparing for the brachial route remains a useful and time-sparing adjunctive measure that guarantees the device's safety and effectiveness in challenging anatomies. PMID:25433281

    In the Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness (ESCAPE) trial, use of a pulmonary artery catheter did not significantly affect advanced heart failure outcomes. However, the success of achieving the targeted hemodynamic goals of pulmonary capillary wedge pressure (PCWP) of 15 mm Hg and right atrial pressure (RAP) of 8 mm Hg and the association of these goals with clinical outcomes were not addressed. Furthermore, goals with 2 independent variables, PCWP and RAP, left room for uncertainties. We assessed the ability of a single hemodynamic target to achieve a threshold sum of PCWP and RAP as a predictor of all-cause mortality, death-or-transplantation (DT), or death-or-rehospitalization (DR) at 6 months in the pulmonary artery catheter-guided treatment arm of ESCAPE (n = 206). Patients with a posttreatment PCWP + RAP of <30 mm Hg had characteristics similar to those of the population who achieved the ESCAPE hemodynamic goals. This group had 8.7% mortality, 13.0% DT, and 58.7% DR at 6 months. The contrasting cohort with PCWP + RAP of ≥30 mm Hg had 45.3% mortality, 54.7% DT, and 84.9% DR at 6 months, with greater relative risk (RR) of death (RR 5.76), DT (RR 4.92), and DR (RR 1.80) and higher prevalence of jugular venous pulsation, edema, hepatomegaly, and ascites at admission and discharge. In conclusion, PCWP + RAP of 30 mm Hg posttreatment, obtained early in the index hospitalization, may represent as a simple congestion index that has prognostic value for heart failure survival and readmission rates at 6 months and as a warning signal for more aggressive intervention, thus warranting further validation.

    Full Text Available Several protective measures have been described to prevent contrast-induced nephropathy (CIN. This study is aimed to evaluate the effect of a high dose of N-acetylcysteine (NAC plus hydration, a low dose of NAC plus ascorbic acid and hydration or hydration alone on the prevention of CIN in high-risk patients undergoing elective coronary artery intervention. We conducted a randomized, prospective, placebo-controlled trial of 105 high-risk patients undergoing elective cardiac catheterization. The patients were divided into three different groups: Group A (n = 30, NAC 1200 mg orally before angiography and 1200 mg orally twice daily for three doses along with good hydration; Group B (n = 30, NAC 600 mg before angiography and 600 mg orally twice daily for three doses plus ascorbic acid (3000 mg one dose before angiography and 2000 mg two doses after angiography and good hydration; and Group C (n = 45, hydration with 0.9% saline started just before contrast media injection and continued for 12 h at a rate 1.0 mL/kg/min after angiography or 0.5 mL/kg/h in cases with overt heart failure for 12 h. CIN was defined as an increase in serum creatinine of >25% of baseline or an absolute increase of 0.5 mg/dL above baseline after 48 h. The incidence of CIN was significantly lower in Group A (6.66% compared with Group B (16.66% or Group C (17.77%. The difference between Groups A and B and between Groups A and C was also highly significant (P = 0.001. In contrast, the difference between Groups B and C was not statistically significant (P = 0.37. Our study indicates that high doses of NAC plus hydration provide better protection against CIN than combination therapy of NAC and ascorbic acid plus hydration, or hydration alone.

    Increasingly, imaging administrators are gaining oversight for the cardiac cath lab as part of imaging services. Significant daily challenges include physician and staff demands, as well as patients who in many cases require higher acuity care. Along with strategic program driven responsibilities, the management role is complex. Critical elements that are the major impacts on cath lab management, as well as the overall success of a cardiac and vascular program, include program quality, patient safety, operational efficiency including inventory management, and customer service. It is critically important to have a well-qualified cath lab manager who acts as a leader by example, a mentor and motivator of the team, and an expert in the organization's processes and procedures. Such qualities will result in a streamlined cath lab with outstanding results. PMID:22720540

    Objective To establish rabbit model of embolic middle cerebral artery occlusion stroke with clots through selective transfemoral internal carotid catheterization(ICA), and evaluate the feasibility and stability of the technique. Methods A total of 30 New Zealand white rabbits were enrolled, either gender, with mean age of 14-month old and mean body weight of 4.1 kg, which were divided into control group(n=10) and experimental group(n = 20). Both groups received selective transfemoral ICA and angiography, with 1-5 clots injected in experimental group and only the contrast media injected in control group. Digital subtraction angiography (DSA) was performed to observe cerebral vascular obstruction, the modified Bederson scoring was used to observe neurologic impairment, CT perfusion was performed to observe cerebral blood perfusion, and diffusion weighted imaging (DWI) and 2, 3, 5 -triphenyltetrazolium chloride (TTC) staining were used to observe cerebral infarction. Results Seventeen (85 %) embolic rabbit stroke models in experimental group were successfully established, which manifested occlusion of middle cerebral arteries, neurologic deficits, abnormalities of perfusion, DWI and TTC staining. Three embolic rabbit stroke models were failed, because internal carotid arteries were occluded in 2 rabbits and recanalization occurred in occluded middle cerebral artery in 1 rabbit. No abnormality was observed in control animals. There was obvious difference in CT parameters between 2 groups. Conclusion It is demonstrated that the technique for establishing rabbit models of embolic middle cerebral arteries occlusion stroke with clots through selective transfemoral ICA is simple, micro invasive and reliable. Selection of appropriate clots and familiarity with the anatomy and variation of ICA could obviously improve the stability and reproducibility of focal cerebral ischemia model in rabbits.%目的 经股动脉途径行选择性颈内动脉插管建立兔大脑中动

Meta-analysis was conducted by u-sing Rev Man 5. 1, or descriptive analysis was performed. Results Four quasi-randomized controlled trials and 14 cohort studies involving 6233 patients were included. The results of meta-analysis showed that PICCs inserted through the cephalic vein developed significantly higher incidence of phlebitis than through the basilic vein[OR = 0. 12, 95%CI(0. 04,0. 38) ,P = 0. 0002]. PICCs placed via the cephalic vein had more significant difficulty in advancing the catheters than via the basilic veins[OR = 0. 26,95%CI(0. 10, 0. 67) ,P = 0. 005]. No statistical differences were found in catheterization success rate and incidence of complications when PICCs inserted in both arms. Conclusion PICC placement through basilic vein shows advantages in improving catheterization success rate and reducing complications. Influence of PICC placement through different arms on catheterization success rate and complications should be further studied. PICCs placed on the affected arm of breast cancer surgery should be very cautious.%目的 系统评价经不同静脉和上肢置入PICC对穿刺置管成功率、并发症发生率的影响.方法 计算机检索Cochrane图书馆、JBI循证护理中心图书馆、MEDLINE、EMbase、CBM、CNKI辅

    Full Text Available OBJECTIVE: to seek the best evidence available in the literature concerning the knowledge produced and related to the techniques of intermittent and indwelling urinary catheterization, so as to place the nursing care given to patients submitted to urinary catheterization on a scientific foundation and to prevent urinary tract infections. METHOD: the literature search was undertaken in the Pubmed and Cochrane databases for the development of the integrative review. The sample was of 34 articles. These were analyzed by two independent researchers using an instrument adapted for ascertaining the level of evidence and the grade of recommendation, in addition to the use of the Jadad scale. RESULTS: the evidence available related to the nursing care for patients submitted to urinary catheterization is: the infection rate in the urinary tract does not alter whether the perineum is cleaned with sterile water or not, or with the use of povidone-iodine solution or chlorhexidine; or using clean or sterile technique. The use of an intermittent catheter with clean technique results in low rates of complications or infections compared to the use of an indwelling catheter. The removal of the catheter in up to 24 hours after surgery and the use of an antimicrobial-impregnated or hydrophilic-coated catheter reduce urinary tract infection . CONCLUSIONS: there are controversies in relation to periurethral cleansing technique, the type of material the catheter is made of, and some procedures for the maintenance and removal of the catheter. This review's results represent an updating of the nurse's conducts and decision-making for the prevention of urinary tract infections in urinary catheterization.OBJETIVO: buscar las mejores evidencias disponibles en la literatura sobre el conocimiento producido y relacionado a la técnica de cateterismo urinario intermitente y de demora para apoyar científicamente el cuidado de enfermería prestado al paciente sometido al

    Traditional methods of identifying partial anomalous pulmonary venous connection to the right atrium in the presence of an atrial defect are not always reliable. Twenty patients were studied with a new technique in which the catheter is introduced into the right superior pulmonary vein followed by echocardiographic assessment of the catheter position in relation to the left atrium and atrial septum. The insertion site of the right pulmonary veins was detected in every patient and in ten patients has been verified at operation. This approach can be performed rapidly and appears to be accurate as well as reliable.

    Full Text Available Venous malformations are rare but possible findings too, constituting a further risk factor for central venous catheter procedures. Herein we describe a case of death because of an innominate vein perforation by a catheter that incidentally was tucked into a sacciform malformation. Even if the technology advancement is constantly offering us new investigation tools, up to now diagnostic options are limited in the detection of those malformations that could potentially lead to dramatic complications as the described one. The present work raises the awareness about rare venous anomalies and their potential clinical implications. A proper literature review and diagnostic implementation proposal are reported.

    Full Text Available Aims and Objectives: The risk assessment of epidural hematoma due to catheter placement in patients undergoing cardiac surgery is essential since its benefits have to be weighed against risks, such as the risk of paraplegia. We determined the risk of the catheter-related epidural hematoma in cardiac surgery based on the cases reported in the literature up to September 2012. Materials and Methods: We included all reported cases of epidural catheter placement for cardiac surgery in web and in literature from 1966 to September 2012. Risks of other medical and non-medical activities were retrieved from recent reviews or national statistical reports. Results: Based on our analysis the risk of catheter-related epidural hematoma is 1 in 5493 with a 95% confidence interval (CI of 1/970-1/31114. The risk of catheter-related epidural hematoma in cardiac surgery is similar to the risk in the general surgery population at 1 in 6,628 (95% CI 1/1,170-1/37,552. Conclusions: The present risk calculation does not justify not offering epidural analgesia as part of a multimodal analgesia protocol in cardiac surgery.

    Prior validation studies have established that simultaneously measured catheter (cath) and Doppler mean pressure gradients (MPG) correlate closely in evaluation of aortic stenosis (AS). In clinical practice, however, cath and Doppler are rarely performed simultaneously; which may lead to discrepant results. Accordingly, our aim was to ascertain agreement between these methods and investigate factors associated with discrepant results. We reviewed findings in 100 consecutive evaluations for AS performed in 97 patients (mean age 72 +/- 10 yr) in which cath and Doppler were performed within 6 weeks. We recorded MPG, aortic valve area (AVA), cardiac output, and ejection fraction (EF) by both methods. Aortic root diameter, left ventricular end-diastolic dimension (LVIDd) and posterior wall thickness (PWT) were measured by echocardiography and gender, heart rate, and heart rhythm were also recorded. An MPG discrepancy was defined as an intrapatient difference > 10 mmHg. Mean pressure gradients by cath and Doppler were 36 +/- 22 mmHg and 37 +/- 20 mmHg, respectively (P = 0.73). Linear regression showed good correlation (r = 0.82) between the techniques. An MPG discrepancy was found in 36 (36%) of 100 evaluations; in 19 (53%) of 36 evaluations MPG by Doppler was higher than cath, and in 17 (47%) of 36, it was lower. In 33 evaluations, EF differed by >10% between techniques. Linear regression analyses revealed that EF difference between studies was a significant predictor of MPG discrepancy (P = 0.004). Women had significantly higher MPG than men by both cath and Doppler (43 +/- 25 mmHg versus 29 +/- 15 mmHg [P = 0.001]; 42 +/- 23 mmHg versus 32 +/- 15 mmHg [P = 0.014], respectively). Women exhibited discrepant results in 23 (47%) of 49 evaluations versus 13 (25%) of 51 evaluations in men (P = 0.037). After adjustment for women's higher MPG, there was no statistically significant difference in MPG discrepancy between genders (P = 0.22). No significant interactions between MPG and aortic root diameter, relative wall thickness (RWT), heart rate, heart rhythm, cardiac output, and time interval between studies were found. In clinical practice, significant discrepancies in MPG were common when cath and Doppler are performed nonsimultaneously. No systematic bias was observed and Doppler results were as likely yield lower as higher MPGs than cath. EF difference was a significant predictor of discrepant MPG. Aortic root diameter, relative wall thickness, heart rate, heart rhythm, cardiac output, presence or severity of coronary artery disease, and time interval between studies were not predictors of discrepant results.

    Purpose: Comparison of the efficacy of VasoSeal {sup trademark} and a mechanical compression system (Compressar {sup trademark}) for percutaneous hemostasis after femoral arterial catheterization of patients with arterial occlusive disease. Materials and Methods: 60 patients underwent either diagnostic angiography or interventional procedures. The level of anticoagulation, blood pressure, and activation clotting time were recorded, and the time to hemostasis after sheath removal was measured. VasoSeal {sup trademark} application was considered ''successful'' if the compression time was less than two minutes. On the subsequent day as well as 4 months later, color coded Doppler ultrasound was performed to register treatment success and potential (late) complications. Results: 57 patients qualified for inclusion in this study. In 21 of the 26 patients who underwent the procedure with the VasoSeal {sup trademark}, immediate hemostasis was achieved within 1.75 minutes. In all 31 patients who had the Compressar {sup trademark} applied, hemostasis was successful with a mean compression time of 17.4 minutes. Thus, VasoSeal {sup trademark} significantly reduced hemostasis time irrespective of anticoagulation status, but it had a much higher incidence of minor local complications (bleeding, hematoma) compared to the control group (34.6% vs. 5.8%). The technical success was lower with VasoSeal {sup trademark} than with Compressar {sup trademark} (81% vs. 100%). Both groups had no severe or late complications. Conclusion: According to our results, VasoSeal {sup trademark} does not provide a suitable alternative compared to the effective, safe and cheap application of Compressar {sup trademark} as a hemostatic device.

METHODS: Cohort prospective study, evaluating adult patients admitted in a teaching intensive care unit (ICU. Catheter placement was performed by an ICU medical resident. The patient's baseline characteristics, vessel's position and operator experience were the evaluated variables. The main outcomes were cannulation success rate and incidence of major complications. RESULTS: A total of 118 consecutive patients were enrolled between May 2008 and November 2009. The success rate of ultrasound guided catheter placement was 90% (106/118, 77% in the first attempt. Major complications occurred in 4% of the cases (n = 5 and were not associated with the analyzed variables. Inability to place the guide wire was the reason for 58% (7/12 of the failures. Operators with more than 15 previous ultrasound guided cannulations had an increased success rate (95% vs. 79%, p = 0.01 and increased failure was related to previous catheterization (26% vs. 7%, p = 0.02.

    cardiac catheterization, according to the Adaptation Theory of Calista Roy. It was developed in a cardiology unit in a hospital in Fortaleza, CE, from January to July, 2005. A semi-structured interview was used, with 18 elderly patients, in pre-catheterization period. The analysis identified the nursing diagnoses: alteration in the maintenance of the health, anxiety, fear and alteration in the family process. The nursing actions were: to create a trust climate for the aged before the exam; to listen and to respect feelings faiths and referring values to the situation; to guide the patient with relationships to the procedure. The use of this theory, allowed in recognizing that patients, by means of incentives, can unchain answers some positive times other negative times, fitting to the nurse to act as mediator.

    Full Text Available Background: Contrast-induced nephropathy (CIN represents an increasing healthcare burden and challenge especially in the scenario of increasing frequency of diagnostic imaging and interventional procedures. Frequency of CIN varies widely depending on the population. There is paucity of data regarding CIN in our population. The risk of CIN is elevated and is of clinical importance in patients with estimated glomerular filtration rate (GFR 60 ml/mt and GFR 30 – 60 ml/mt. Patients who developed CIN were followed up with serum creatinine measurement on the 5th day post procedure. Results: Among 850 patients enrolled for the study, 15 patients were lost for follow-up. Of the rest 835 patients, 535(64% were having GFR > 60ml /mt and 300 (36% having GFR of 30-60 ml/mt. The procedure was coronary angiography in 795(95% patients and percutaneous coronary intervention (PCI in 40 (5% patients. CIN occurred in 5 patients (0.59 %. 3 of 300 patients in the group with GFR 30 – 60 ml/mt and 2 of 535 patients in the group with GFR > 60ml/mt had CIN (1% vs 0.4% (p value 0.260 NS. Among the 500 hypertensives in the study population, 3 (0.6% developed CIN. CIN was seen in 4 out of 635 diabetics (0.6%, where as it occurred in 1 out of 200 non diabetics (0.5% (p value 0.589 NS. 4 among 100 patients with LV dysfunction and 1 out of 735 patients with normal LV function developed CIN (4% vs 0.13% (p value 0.001 . Conclusions: Overall incidence of CIN is low in the study population. Even in the group with low GFR, incidence of CIN is low. Left ventricular dysfunction is the only risk factor predicting development of CIN.

Currently, they are part of the standard medical care for oncohematologic patients. However, apart from mechanical and thrombotic complications, there are also complications associated with biofilm development inside the catheters. These biofilms increase the cost of medical assistance and extend hospitalization. The most frequently involved micro-organisms in these infections are gram-positive cocci. Many efforts have been made to understand biofilm formation within the lumen catheters, and to resolve catheter-related infection once it has been established. Apart from systemic antibiotic treatment, the use of local catheter treatment (ie, antibiotic lock technique is widely employed. Many different antimicrobial options have been tested, with different outcomes, in clinical and in in vitro assays. The stability of antibiotic concentration in the lock solution once instilled inside the catheter lumen remains unresolved. To prevent infection, it is mandatory to perform hand hygiene before catheter insertion and manipulation, and to disinfect catheter hubs, connectors, and injection ports before accessing the catheter. At present, there are still unresolved questions regarding the best antimicrobial agent for catheter-related bloodstream infection treatment and the duration of concentration stability of the antibiotic solution within the lumen of the port.

    The design principles that drove the development of a new cardiovascular x-ray digital flat panel (DFP) detector system are presented, followed by assessments of imaging and dose performance achieved relative to other state of the art FPD systems. The new system (GE Innova 2100 IQ TM) incorporates a new detector with substantially improved DQE at fluoroscopic (73%@1μR) and record (79%@114uR) doses, an x-ray tube with higher continuous fluoro power (3.2kW), a collimator with a wide range of copper spectral filtration (up to 0.9mm), and an improved automatic x-ray exposure management system. The performance of this new system was compared to that of the previous generation GE product (Innova 2000) and to state-of-the art cardiac digital x-ray flat panel systems from two other major manufacturers. Performance was assessed with the industry standard Cardiac X-ray NEMA/SCA and I phantom, and a new moving coronary artery stent (MCAS) phantom, designed to simulate cardiac clinical imaging conditions, composed of an anthropomorphic chest section with stents moving in a manner simulating normal coronary arteries. The NEMA/SCA&I phantom results showed the Innova 2100 IQ to exceed or equal the Innova 2000 in all of the performance categories, while operating at 28% lower dose on average, and to exceed the other DFP systems in most of the performance categories. The MCAS phantom tests showed the Innova 2100 IQ to be significantly better (p << 0.05) than the Innova 2000, and significantly better than the other DFP systems in most cases at comparable or lower doses, thereby verifying excellent performance against design goals.

    The purpose of the study is to assess the impact of superselective neurotransmitter metabolic therapy in patients in a vegetative state. Superselective intraarterial infusion was conducted on 26 patients with relevant international criteria for the diagnosis of vegetative state. Comprehensive assessment of neurologic symptoms and severity of low metabolism on PET scan allowed to select the vascular pool, for the catheter installation. The catheter was placed either in the carotid or the vertebrobasilar pool. Infusion of neurotransmitter agents was conducted for 7 days continuously. Control of the level of metabolism of labeled glucose in the brain (PET) was performed within 2 weeks after arterial infusion. 14 out of 26 patients showed a positive trend of changes in energy metabolism of the brain. However, only 7 out of 14 patients showed further recovery of consciousness. The data confirms that the delivery path and a combination of medications play a definite role in the effectiveness of vegetative state therapy. PMID:21692220

    Two-dimensional-three-dimensional (2D-3D) registration between intra-operative 2D digital subtraction angiography (DSA) and pre-operative 3D computed tomography angiography (CTA) can be used for roadmapping purposes. However, through the projection of 3D vessels, incorrect intersections and overlaps between vessels are produced because of the complex vascular structure, which makes it difficult to obtain the correct solution of 2D-3D registration. To overcome these problems, we propose a registration method that selects a suitable part of a 3D vascular structure for a given DSA image and finds the optimized solution to the partial 3D structure. The proposed algorithm can reduce the registration errors because it restricts the range of the 3D vascular structure for the registration by using only the relevant 3D vessels with the given DSA. To search for the appropriate 3D partial structure, we first construct a tree model of the 3D vascular structure and divide it into several subtrees in accordance with the connectivity. Then, the best matched subtree with the given DSA image is selected using the results from the coarse registration between each subtree and the vessels in the DSA image. Finally, a fine registration is conducted to minimize the difference between the selected subtree and the vessels of the DSA image. In experimental results obtained using 10 clinical datasets, the average distance errors in the case of the proposed method were 2.34±1.94mm. The proposed algorithm converges faster and produces more correct results than the conventional method in evaluations on patient datasets. PMID:26824922

    International Nuclear Information System (INIS)

    We report a 12-year-old boy who presented with abdominal pain and who was found to have an aneurysm of the abdominal aorta (AAA). The patient was born from a quadruplet pregnancy induced by in vitro fertilization. Postnatal transient respiratory distress required assisted ventilation that had been monitored by two consecutive umbilical arterial catheters (UAC). AAA is a rare condition in childhood. Infection and/or trauma are known to be the most frequent causes. Most of the reported cases have occurred in children in whom a UAC had been placed during the neonatal period. In this patient the delay between UAC placement and diagnosis was considerable. At the time of this report the patient had remained well during a follow-up of 8 years after treatment. (orig.)

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the dose received by health professionals in the hemodynamic sector of a university hospital in Sao Paulo city. A self-applied questionnaire was used to delineate the profile of health professionals, taking into account sociodemographic variables and variables related to the work with ionizing radiation. The assessment of occupational doses was performed by consulting of the individual dose records of the institution database from 2000 to 2009. A total of 240 records was evaluated, corresponding to 38 active professionals (2009), divided in different professional category: physician, nurses, radiologic technologists and nursing assistants. The annual doses were compared with the limits established by national regulatory authorities. Based on the effective doses received and recorded during the studied period, experimental measures were performed with TL dosimeters in five physicians to evaluate the equivalent dose, in the left hand, during hemodynamic procedures. In addition, the radioprotection measures adopted by health professionals were verified. This study allowed delineating the profile of medical staff that integrates the hemodynamic service as well as knowing the distribution of their doses in relation to limits over the years. (author)

    1989-01-01

    Infusion thrombophlebitis is a common troublesome complication of intravenous therapy. This study compared peripheral intravenous Teflon and Vialon catheters. The incidence of phlebitis, bacterial adherence and mechanical resistance (distortion) were assessed on 170 catheters, 85 of each type. The Vialon catheter resulted in less phlebitis than the Teflon one (18 vs. 35; p less than 0.01). During the period 49 to 72 h after the insertion of the catheter, the risk of phlebitis in the Teflon group was twice that in the Vialon group. The study of bacterial adherence using a semi-quantitative culture method demonstrated that 9.0% of the catheters were infected with Staphylococcus epidermidis. There was no statistically significant difference between the two groups (5.7% Vialon group vs. 12.5% Teflon group). The Teflon catheters were much more distorted than vialon catheters: 1.7% vs. 55.7% in the macroscopic study; 1.75% vs. 8.2% in the microscopic study. As Vialon softens at body temperature, it would seem likely that it generates a lesser degree of endothelial injury, explaining the lower rate of phlebitis with Vialon catheters. PMID:2633660

Given her history of opioid tolerance and after an informative discussion, a continuous femoral PNB was planned for in this 34-year-old female undergoing TKR. A Humate-P intravenous infusion was started and the patient was positioned supinely. Using sterile technique with ultrasound guidance, a Contiplex 18 Gauge Tuohy needle was advanced in plane through the fascia iliaca towards the femoral nerve. A nerve catheter was threaded through the needle and secured without complications. Postoperatively, a levobupivacaine femoral catheter infusion was maintained, and twice daily Humate-P intravenous infusions were administered for 48 hours; enoxaparin thromboprophylaxis was initiated thereafter. The patient was discharged uneventfully on postoperative day 4. Given documentation of delayed, unheralded bleeding from PNB in coagulopathic patients, we recommend individualized PNB in vWD patients. Multidisciplinary team involvement is required to guide factor supplementation and thromboprophylaxis, as is close follow-up to elicit signs of bleeding throughout the delayed postoperative period.

    We report a 12-year-old boy who presented with abdominal pain and who was found to have an aneurysm of the abdominal aorta (AAA). The patient was born from a quadruplet pregnancy induced by in vitro fertilization. Postnatal transient respiratory distress required assisted ventilation that had been monitored by two consecutive umbilical arterial catheters (UAC). AAA is a rare condition in childhood. Infection and/or trauma are known to be the most frequent causes. Most of the reported cases have occurred in children in whom a UAC had been placed during the neonatal period. In this patient the delay between UAC placement and diagnosis was considerable. At the time of this report the patient had remained well during a follow-up of 8 years after treatment. (orig.)

    Coronary angiogram is an imperative tool for diagnosis of coronary artery diseases, in which cine-angiography is a commonly used method. Although the angiography proceeds under radiation, the potential risk of radiation exposure for both the patients and the operators was seldom noticed. In this study, the absorbed radiation dose in stored-fluorography mode was compared with that in cine-angiography mode by using optically simulated luminescent dosimeters to realize their effects on radiation dose. Patients received coronary angiogram via radial artery approach were randomized into the stored-fluorography group (N=30) or the cine-angiography group (N=30). The excluded criteria were: 1. women at pregnancy or on breast feeding, 2. chronic kidney diseases with glomerular filtration rate less than 60 mL/min. During the coronary angiogram, absorbed dose of the patients and the operator radiation exposure was measured with optically simulated luminescent dosimeter (OSLD). The absorbed dose of the patients in the stored-fluorography group (3.13±0.25 mGy) was apparently lower than that in the cine-angiography group (65.57±5.37 mGy; Pcine-angiography (0.6519μGy). Compared with traditional cine-angiography mode, the stored-fluorography mode can apparently reduce radiation exposure of the patients and the operator in coronary angiogram.

    Myeloid sarcoma (MS) is a rare extramedullary myeloid tumour. It has been reported in various sites, including lymph node, bone, skin, soft tissue, various organs and the CNS. It may precede or occur concurrently with acute myeloid leukemia. Urinary bladder involvement is extremely uncommon. We report a 70-year-old female who had MS of the urinary bladder, presented with frank and persistent hematuria associated with lower abdominal pain. She subsequently had tumour seeding in the abdominal skin via percutaneous suprapubic catheter. Tumours from both the urinary bladder and skin showed immature cells that were immunoreactive toward LCA (focal), MPO (strong), CD99 (weak) and CD117 (weak). Summary of cases in the literature is presented. The potential of its misdiagnosis and the useful markers for the diagnosis of MS are discussed. PMID:21874752

    Full Text Available Abstract Background A central venous catheter (CVC currently represents the most frequently adopted intravenous line for patients undergoing infusional chemotherapy and/or high-dose chemotherapy with hematopoietic stem-cell transplantation and parenteral nutrition. CVC insertion represents a risk for pneumothorax, nerve or arterial punctures. The aim of this prospective observational study was to explore the safety and efficacy of CVC insertion under ultrasound (US guidance and to confirm its utility in clinical practice in cancer patients. Methods Consecutive adult patients attending the oncology-hematology department were eligible if they had solid or hematologic malignancies and required CVC insertion. Four types of possible complication were defined a priore: mechanical, thrombotic, infection and malfunctioning. The patient was placed in Trendelenburg's position, a 7.5 MHZ puncturing US probe was placed in the supraclavicular site and a 16-gauge needle was advanced under real-time US guidance into the last portion of internal jugular vein. The Seldinger technique was used to place the catheter, which was advanced into the superior vena cava until insertion into right atrium. Within two hours after each procedure, an upright chest X-ray and ultrasound scanning were carried out to confirm the CVC position and to rule out a pneumotorax. CVC-related infections, symptomatic vein thrombosis and malfunctioning were recorded. Results From December 2000 to January 2009, 1,978 CVC insertional procedures were applied to 1,660 consecutive patients. The procedure was performed 580 times in patients with hematologic malignancies and 1,398 times those with solid tumors. A single-needle puncture of the vein was performed on 1,948 of 1,978 procedures (98.48%; only eighteen attempts among 1,978 failed (0.9%. No pneumotorax, no major bleeding, and no nerve puncture were reported; four cases (0.2% showed self-limiting hematomas. The mean lifespan of CVC was 189.7 +/- 18.6 days (range 7-701. Symptomatic deep-vein thrombosis of the upper limbs developed in 48 patients (2.42%. Catheter-related infections occurred in 197 (9.96% of the catheters inserted. They were successfully treated with antibiotics and only in 48 (2.9% patients definitive CVC removal was required for infection and/or thrombosis or malfunctioning. Conclusions This study represents the largest published series of consecutive patients with cancer undergoing CVC insertion under US guidance; this procedure allowed the completion of the therapeutic program for 1,930/1,978 (97.6% of the catheters inserted. The absence of pneumotorax and other major complications indicates that US guidance should be mandatory for CVC insertion in patients with cancer.

    In this paper, we have discussed the influence of copper nanoparticles on a blood flow through composite stenosed artery with permeable walls. The nature of blood is discussed mathematically by considering it as viscous nanofluid. The study is carried out for a blood vessel under mild stenosis approximations and expressions of the temperature, velocity, resistance impedance to flow, wall shear stress and the pressure gradient is obtained by using corresponding boundary conditions. Results for the effects of permeability on blood flow through composite stenosis have been discussed graphically. The considered analysis also summarizes that the drug copper nanoparticles are efficient to reduce hemodynamics of stenosis and could be helpful to predict important uses for biomedical applications. Results indicate that nanoparticles are helpful as drug carriers to minimize the effects of resistance impedance to blood flow or coagulation factors due to stenosis. PMID:27393802

    Background/Purpose: Compared with trans-femoral percutaneous coronary intervention (TFI), trans-radial PCI (TRI) has a lower risk of bleeding, access site complications and hospital costs, and is preferred by patients. However, TRI accounts for a minority of PCIs in the US, and there is currently little research that explores why. Methods/Material: We conducted a national survey in February 2013 to assess perceptions of TRI vs. TFI, and barriers to TRI adoption and implementation among interventional cardiologists employed by the US Veterans Health Administration (VHA), and linked these data to site-level TRI annual rates for 2013. Results: We received 78 completed surveys (32% response rate). Respondents at sites that perform few or no TRIs identified increased radiation exposure as the greatest barrier while at sites that perform a high percentage of TRIs respondents identified the steep learning curve as the greatest barrier. Majorities of survey respondents at all sites rated TRI as superior on 5 of 7 criteria, including patient comfort and bleeding complications, but rated TFI as superior on procedure time and procedure success. Conclusions: Even interventional cardiologists at sites that perform few or any TRIs recognized the superiority of TRI for patient comfort and safety, but rated it inferior to TFI on procedure time and technical results. Interventional cardiologists at high-TRI labs rated TRI as equivalent on procedure time and technical results. Efforts to increase TRI adoption and implementation may be more successful if they emphasize that procedure times and technical results depend on achieving proficiency. - Highlights: • Sites with few TRIs identified increased radiation exposure as the greatest barrier. • Sites with many TRIs identified the steep learning curve as the greatest barrier. • TFI was rated superior on procedure time and procedure success. • TRI was rated superior on all other criteria.

    Background: Adenosine is the gold standard for augmenting coronary flow during fractional flow reserve (FFR) testing of intermediate coronary stenoses. However, intravenous infusion is time-consuming and intracoronary injection is subject to variability. Regadenoson is a newer adenosine alternative administered as a single intravenous bolus during nuclear stress testing, but its efficacy and safety during FFR testing have been evaluated only in small, single-center studies. Methods: We pooled data from 5 academic hospitals, in which patients undergoing clinically-indicated FFR prospectively underwent comparison of intravenous adenosine infusion (140–175 mcg/kg/min) versus regadenoson bolus (400 mcg). Hemodynamics and symptoms with adenosine were recorded until maximal hyperemia occurred, and after returning to baseline hemodynamics, regadenoson was administered and monitoring was repeated. In a subset of patients with coronary flow data, average peak velocity (APV) at the distal flow sensor was recorded. Results: Of 149 patients enrolled, mean age was 59 ± 9 years, 76% were male, and 54% underwent testing of the left anterior descending artery. Mean adenosine-FFR and regadenoson-FFR were identical (0.82 ± 0.10) with excellent correlation of individual values (r = 0.96, p < 0.001) and no difference in patient-reported symptoms. Four patients (2.6%) had discrepancies between the 2 drugs for the clinical decision-making cutoff of FFR ≤ 0.80. Coronary flow responses to adenosine and regadenoson were similar (APV at maximal hyperemia 36 cm/s for both, p = 0.81). Conclusions: Regadenoson single-bolus administration has comparable FFR, symptoms, and coronary flow augmentation when compared with standard intravenous adenosine infusion. With its greater ease of administration, regadenoson may be a more “user-friendly” option for invasive ischemic testing.

    The hierarchical interaction between electrical signals of the brain and heart is not fully understood. We hypothesized that the complexity of cardiac electrical activity can be used to predict changes in encephalic electricity after stress. Most methods for analyzing the interaction between the heart rate variability (HRV) and electroencephalography (EEG) require a computation-intensive mathematical model. To overcome these limitations and increase the predictive accuracy of human relaxing states, we developed a method to test our hypothesis. In addition to routine linear analysis, multiscale entropy and detrended fluctuation analysis of the HRV were used to quantify nonstationary and nonlinear dynamic changes in the heart rate time series. Short-time Fourier transform was applied to quantify the power of EEG. The clinical, HRV, and EEG parameters of postcatheterization EEG alpha waves were analyzed using change-score analysis and generalized additive models. In conclusion, the complexity of cardiac electrical signals can be used to predict EEG changes after stress.

  11. A new design of a lead-acrylic shield for staff dose reduction in radial and femoral access coronary catheterization

    International Nuclear Information System (INIS)

    Today's standard radiation protection during coronary angiography and percutaneous coronary interventions is the combined use of lead acrylic shields and table-mounted lower body protection. Ambient dose measurements, however, have shown that these protection devices need improvement. Using an anthropomorphic physical phantom, various scenarios were investigated with respect to personnel exposure: (a) enlarging the shield (b) adding a flexible protective curtain to the bottom side of the shield, and (c) application of radioprotective patient drapes. For visualization of the dose reduction effect, Monte Carlo simulations were performed. The flexible curtain in contact with the patient's body reduces the ambient dose rate at the operator's position by up to (87.5 % ± 7.1) compared to the situation with the bare shield. The use of both the flexible curtain and the patient drape reduces the ambient dose rate by up to (90.8 % ± 7). Similar results were achieved for the assisting personnel when they were positioned next to the operator. In addition, the enlarged shield provides better protection of the head region of tall operators. Adding a flexible protective curtain to the bottom side of the shield can protect operators from high doses, especially for body parts which are not protected by lead aprons, e.g. head, and eye lenses. This may be important with respect to lower dose limits for eye lenses in future. The protective effect in real-life working conditions is still being evaluated in an ongoing clinical study.

    Since cone-beam computed tomography (CT) has been adapted for use with a C-arm system it has brought volumetric CT capabilities in the interventional suite. Although cone-beam CT image resolution is far inferior to that generated by traditional CT scanners, the system offers the ability to place an access needle into position under tomographic guidance and use the access to immediately begin a fluoroscopic procedure without moving the patient. We describe a case of a “jailed” enlarging internal iliac artery aneurysm secondary to abdominal aortic aneurysm repair, in which direct percutaneous puncture of the internal iliac artery aneurysm sac was performed under cone-beam CT guidance.

    We report on 6 women with continuous urinary incontinence as a late complication of an indwelling urethral catheter for neurogenic bladder. Pressure necrosis by the balloon resulted in progressive destruction of the entire urethra, with subsequent incontinence despite the catheter. Surgical attempts at bladder neck closure to correct the incontinence generally have been unsuccessful. Instead of supravesical urinary diversion, we performed transvaginal closure of the bladder neck and percutaneous placement of a permanent suprapubic tube cystostomy. All 6 patients remained dry after closure and none has shown upper urinary tract deterioration at followup for as long as 5 years. PMID:4040980

    The electrocardiogram (ECG) is the most widely used imaging tool helping in diagnosis and initial management of patients presenting with symptoms compatible with acute coronary syndrome. Acute ischemia affects the configuration of the QRS complexes, the ST segments and the T waves. The ECG should be read along with the clinical assessment of the patient. ST segment elevation (and ST depression in leads V1 -V3 ) in patients with active symptoms usually indicates acute occlusion of an epicardial artery with ongoing transmural ischemia. These patients should be triaged for emergent reperfusion therapy per current guidelines. However, many patients have ST segment elevation secondary to nonischemic causes. ST depression in leads other than V1 -V3 usually are indicative of subendocardial ischemia secondary to subocclusion of the epicardial artery, distal embolization to small arteries or spasm supply/demand mismatch. ST depression may also be secondary to nonischemic etiologies, such as left ventricular hypertrophy, cardiomyopathies, etc. Knowing the clinical scenario, comparison to previous ECG and subsequent ECGs (in cases that there are changes in the quality or severity of symptoms) may add in the diagnosis and interpretation in difficult cases. This review addresses the different ECG patterns, typically seen in patients with active symptoms, after resolution of symptoms and the significance of such changes when seen in asymptomatic patients.

    A hybrid X-ray and magnetic resonance imaging system (XMR) has been proposed as an interventional guidance for cardiovascular catheterisation procedure. However, very few hospitals can benefit from the XMR system because of its limited availability. In this paper we describe a new guidance strategy for cardiovascular catheterisation procedure. In our technique, intra-operative patient position is estimated by using a chest surface reconstructed from a photogrammetry system. The chest surface is then registered with the same surface derived from pre-procedure magnetic resonance (MR) images. The catheterisation procedure can therefore be guided by a roadmap derived from the MR images. Patients were required to hold the breath at end expiration during MRI acquisition. The surface matching accuracy is improved by using a robust trimmed iterative closest point (ICP) matching algorithm, which is especially designed for incomplete surface matching. Compared to the XMR system, the proposed guidance strategy is low cost and easy to set up. Experimental data were acquired from 6 volunteers and 1 patient. The patient data were collected during an electrophysiology procedure. In 6 out of 7 subjects, the experimental results show our method is accurate in term of reciprocal residual error (range from 1.66m to 3.75mm) and constant (closed-loop TREs range from 1.49mm to 3.55mm). For one subject, trimmed ICP failed to find the optimal transform matrix (residual = 4.89, TRE = 9.32) due to the poor quality of the photogrammetry-reconstructed surface. More studies are being carried on in clinical trials.

    The purpose of this study was to evaluate the dose received by health professionals in the hemodynamic sector of a university hospital in Sao Paulo city. A self-applied questionnaire was used to delineate the profile of health professionals, taking into account sociodemographic variables and variables related to the work with ionizing radiation. The assessment of occupational doses was performed by consulting of the individual dose records of the institution database from 2000 to 2009. A total of 240 records was evaluated, corresponding to 38 active professionals (2009), divided in different professional category: physician, nurses, radiologic technologists and nursing assistants. The annual doses were compared with the limits established by national regulatory authorities. Based on the effective doses received and recorded during the studied period, experimental measures were performed with TL dosimeters in five physicians to evaluate the equivalent dose, in the left hand, during hemodynamic procedures. In addition, the radioprotection measures adopted by health professionals were verified. This study allowed delineating the profile of medical staff that integrates the hemodynamic service as well as knowing the distribution of their doses in relation to limits over the years. (author)

    The management of refractory cardiac arrest during invasive coronary procedures has substantial logistical challenges and is typically associated with disappointing outcomes. We describe the case of a young woman with recalcitrant ventricular fibrillation due to acute anterior ST-elevation myocardial infarction caused by occlusion of her proximal left anterior descending artery. Survival without neurological deficit or organ failure was achieved following primary percutaneous reperfusion and a total of 52 min of intra-procedural chest compression support, made possible by the use of an automated chest compression device.

    Full Text Available Mediastinal hematoma is a rare complication following insertion of a central venous catheter with only few cases reported in the English literature. We report a case of a 71-year-old female who was admitted for elective chemoport placement. USG guided right internal jugular access was attempted using the Seldinger technique. Resistance was met while threading the guidewire. USG showed a chronic clot burden in the RIJ. A microvascular access was established under fluoroscopic guidance. Rest of the procedure was completed without any further issues. Following extubation, the patient complained of right-sided chest pain radiating to the back. Chest X-ray revealed a contained white out in the right upper lung field. She became hemodynamically unstable. Repeated X-ray showed progression of the hematoma. Median Sternotomy showed posterior mediastinal hematoma tracking into right pleural cavity. Active bleeding from the puncture site at RIJ-SCL junction was repaired. Patient had an uneventful recovery. Injury to the central venous system is the result of either penetrating trauma or iatrogenic causes as in our case. A possible explanation of our complication may be attributed to the forced manipulation of the dilator or guidewire against resistance. Clavicle and sternum offer bony protection to the underlying vital venous structures and injuries often need sternotomy with or without neck extension. Division of the clavicle and disarticulation of the sternoclavicular joint may be required for optimum exposure. Meticulous surgical technique, knowledge of the possible complications, and close monitoring in the postprocedural period are of utmost importance. Chest X-ray showed to be routinely done to detect any complication early.

  4. Clinically Significant Contrast Induced Acute Kidney Injury after Non-Emergent Cardiac Catheterization - Risk Factors and Impact on Length of Hospital Stay

    International Nuclear Information System (INIS)

    Objective: To evaluate the frequency and risk factors associated with clinically significant contrast-induced nephropathy (CIN) in patients undergoing non-emergent coronary angiography. Study Design: Descriptive study. Place and Duration of Study: The Aga Khan University Hospital, Karachi, from January 2005 to December 2007. Methodology: Case records of patients who underwent coronary angiography with a serum creatinine of >= 1.5 mg/dl at the time of procedure were evaluated. Clinically significant contrast induced nephropathy (CSCIN) was defined as either doubling of serum creatinine from baseline value within a week following the procedure or need for emergency hemodialysis after the procedure. Results: One hundred and sixteen patients met the inclusion criteria. Mean age was 64.0 +- 11.5 years, 72% were males. Overall prevalence of CIN was 17% (rise of serum creatinine by A= 0.5 mg/dl) while that of clinically significant CIN (CSCIN) was 9.5% (11 patients). Patients with CSCIN had significantly lower left ventricular ejection fraction (p = 0.03, OR: 0.24; 95% CI = 0.06 A= 0.91) and higher prevalence of cerebrovascular disease (p < 0.001, OR: 14.66; 95% CI = 3.30 - 65.08). Mean baseline serum creatinine was significantly higher, 3.0 +- 1.5 vs. 2.0 +- 1.1 mg/dl (p = 0.03, OR: 1.47; 95% CI = 1.03 - 2.11) whereas mean GFR estimated by Cockcroft-Gault formula was significantly lower at 25 +- 7.4 vs. 41.0 +- 14.6 ml/minute (p = 0.001, OR = 0.89, 95% CI = 0.84 A= 0.95) at the time of procedure in patients with CSCIN. Mean length of hospital stay was significantly higher in this group compared to those without CIN, 9.0 +- 5.1 vs. 3.0 +- 3.2 days (p = 0.001, OR = 1.31, 95% CI = 1.12 - 1.54). Multivariate analysis revealed low GFR (p = 0.001, OR = 0.88; 95% CI = 0.82 - 0.95) and low ejection fraction (p = 0.03, OR = 0.20; 95% CI = 0.04 - 0.91) to be independent factors associated with CSCIN. No significant differences were noted between the two groups in patients with hypertension, diabetes and heart failure. Conclusion: CSCIN is a significant concern in high risk groups despite prophylaxis. Patients with lower EF, cerebrovascular disease and low GFR at the time of procedure are more likely to have CIN.

  5. Clinical assessment of cardiac performance in chronic lung diseases by using RI multi-gated cardiac pool scan and pulmonary artery catheterization

    International Nuclear Information System (INIS)

    To evaluate biventricular function at rest and hypoxic load in patients with chronic lung diseases, we examined radionuclide angiography in 6 normal controls, 19 patients with chronic obstructive lung diseases (COLD), 14 patients with restrictive lung diseases (RLD), using ECG-gated cardiac blood pool scans, and 7 patients (3 COLD, 4 RLD) were examined by the pulmonary artery catheter. After suitable background correction, left and right ventricular ejection fractions (LVEF and RVEF) were calulated by the formula : RVEF or LVEF = (end-diastole counts- end-systole counts)/end-diastole counts. Cardiac performance was measured at rest and after 20 minutes low oxygen (15 %) load. The results were as follows: 1) RVEF (%) at rest in the RLD group (46.6 ± 8.3 %) was less than that in the control group, and the COLD group (48.7 ± 8.7 %, 48.4 ± 12.4 %). 2) The responses to hypoxia in the COLD group and the RLD group showed absolute increases in RVEF of 8.7 ± 14.1 % and 7.4 ± 8.9 %, and also, mean pulmonary pressure (MPAP), cardiac index (CI) and pulmonary vascular resistance were increased significantly. These results suggest that in patients with chronic lung diseases, RV functions are after-hypoxic load-dependent and multiple cardiac pool image would be of value in the estimation of cardiac performance.

MÉTODOS: Estudo prospectivo, considerando 1.656 cinean-giocoronariografias seguidas de aortografia, entre janeiro/2002 e fevereiro/2004, de pacientes encaminhados à cineangiocoronariografia diagnóstica com história ou não de hipertensão arterial sistêmica (HAS. RESULTADOS: Dos 1.656 pacientes, a idade média foi de 61,6 ± 11,8 anos, 53,8% eram do sexo masculino, 10,2% eram diabéticos, 63,8% apresentavam coronariopatia obstrutiva. A presença de EAR maior que 50% foi observada em 228 (13,8% pacientes, e em 25 (1,5% destes, ocorreu bilateralmente. A coronariopatia obstrutiva foi definida como estenose que causa redução do lúmen do vaso em 50% ou mais, em um, dois ou três vasos principais, denominados uniarterial, biarterial ou triarterial, respectivamente.A quantificação era realizada através da análise visual da angiografia. Comparando os grupos com e sem EAR > 50%, observou-se diferença estatisticamente significativa quanto a gênero, idade, ocorrência de diabete melito, PA e função ventricular esquerda. Não houve diferença significativa, no entanto, quanto à ocorrência de obstrução coronariana > 50%. Quando, porém, a EAR considerada é > 70%, observa-se diferença significativa quanto a PA, associação à obstrução coronariana > 50% e à disfunção ventricular esquerda, maiores no grupo com EAR. CONCLUSÃO: A prevalência de EAR neste estudo foi comparável àquela das grandes casuísticas da literatura e, em razão de sua importância pela associação com HAS e doença renal terminal (DRT e suas seqüelas, devemos estar atentos para seu diagnóstico angiográfico.OBJECTIVE: To determine the prevalence of renal artery stenosis (RAS in patients who have undergone cineangiocoronariography. METHODS: Prospective study of cineangiocoronariography and aortography examinations conducted between January 2002 and February 2004 on 1,656 hypertensive and normotensive patients who underwent the examinations to confirm the diagnosis of obstructive coronary artery disease or valve disease. RESULTS: The average age of the 1,656 patients was 61.6 ± 11.8 years. Eight hundred and ninety-one (53.8% were male, 169 (10.2% were diabetic and 1,054 (63.8% presented obstructive coronary artery disease. Renal stenosis greater than 50% was observed in 228 (13.8% patients, and 25 (1.5% had bilateral stenosis. Obstructive coronary artery disease was defined as stenosis greater than or equal to 50% of the vessel lumen, in one, two or three main arteries, classified as single, double or triple vessels, respectively. Quantification was conducted using visual analysis of the angiography. Comparison of the groups with and without renal artery obstruction > 50%, revealed significant statistical differences in relation to gender, age, diabetes mellitus, blood pressure and left ventricular function. However, no statistical difference was noted in relation to the occurrence of coronary artery obstructions > 50%. Nevertheless, renal artery obstructions > 70%, revealed significant differences in relation to blood pressure, coronary artery obstructions > 50% and left ventricular function, which were all higher in the renal artery obstruction group. CONCLUSION: The prevalence of RAS found in our study was comparable to that reported by major medical literature case studies. RAS is associated with systemic hypertension (SH, end-stage renal disease (ESRD and its sequelae, emphasizing how important it is that we are aware of possible candidates for angiographic diagnosis of this disease.

    Full Text Available Justificación: la mayor área de crecimiento en el uso de propofol ha sido para sedación en salas de operaciones y centros diagnósticos. El dolor a la inyección de propofol es un problema clínico común. Ha habido muchos intentos para reducir el dolor, sin embargo, la inhibición completa no se ha logrado. Métodos: se diseñó una fórmula para la recolección de datos, la cual se aplicó a los pacientes sedados para colonoscopia en la Sala de Endoscopia del Hospital San Juan de Dios. En la citada fórmula se incluyó la escala de dolor a la inyección de propofol, según lo establecido por McCrirrick, y se registraron las variables demográficas, localización y calibre del catéter venoso utilizado, así como los fármacos administrados concomitantemente. Los datos de la fórmula fueron completados por el médico anestesiólogo a cargo de la sedación, y revisados por el investigador. Resultados: un 58% de los pacientes no presentó dolor a la inyección de propofol; un 24,8% presentó dolor leve; un12,8%, dolor moderado, y un 1,7%, dolor intenso. Estadísticamente, el grupo de pacientes al que se le administró propofol en una vía colocada en fosa antecubital, presentó menos dolor que aquellos pacientes a los cuales se les colocó vía en dorso de mano, muñeca o cara anterior de antebrazo (p=0,006. Conclusión: la mejor forma de reducir el dolor a la inyección de propofol, consiste en utilizar una cánula venosa en la fosa antecubital para su administración.Background: The use of propofol has seen its greatest growth in the operating room and diagnostic centers. Pain associated with propofol injection is a common clinical issue. There have been many attempts to reduce pain, however, complete inhibition has not been achieved. Methods: Data was colected from patients sedated with propofol in the Endoscopy room at San Juan de Dios Hospital. The data obtained included the McCrirrick pain on propofol injection scale, demographic variables, caliber and location of venous catheters, as well as concomitant medications. The data was recorded by the treating anesthesiologist and reviewed by the researcher. Results: 58% of patients did not experience pain on propofol injection; 24,8% experienced mild pain, 12,8% moderate pain, and 1,7% severe pain. Statistically, the group of patients that received propofol through a venous catheter in the antecubital fossa, experienced less pain than those with a venous catheter placed in the hand, wrist, or anterior forearm. (p=0,006. Conclusion: The best way to reduce pain on propofol injection is to place the venous catheter in the antecubital fossa.

    目的:探讨全麻单侧膝关节置换术( TKA)患者术中是否留置导尿对患者术后发生尿路刺激症状的影响。方法2015年12月—2016年2月将95例拟行初次单膝TKA手术患者随机分为术前非留置导尿管( NIC)组和术前留置导尿管( IC)组。 IC组( n=48)全麻后留置尿管,于术后24 h内拔除导尿管;NIC组患者( n=47)术中不进行导尿。比较两组术后24 h内尿潴留、尿路刺激征等症状及主观感受。结果 NIC组患者术后出现尿潴留3例,尿路刺激0例,IC组术后出现尿潴留1例、尿路刺激5例,两组尿潴留、尿路刺激发生率比较,差异无统计学意义( P>0.05);两组均无尿路感染发生。术后NIC组患者镇静程度评估量表评分为(3.89±0.31)分,IC 组为(4.06±0.24)分,两组比较差异有统计学意义(t=-2.941,P0.05) . No urinary tract infection cases in two groups. The score of sedative degree of patients in the NIC group was (3.89±0.31), and was (4.06±0.24) in the IC group (t=-2.941,P<0.05).Conclusions The risk of urinary irritation was higher in IC group than in NIC group when received total anesthesia in TKA. Indwelling urinary catheter is not routinely needed in TKA, non-indwelling urinary catheter can contribute to increasing the comfort of surgery.

    Approximately 10 per cent of patients referred for coronary arteriography because of chest pain have angiographically normal coronary arteries and no other heart disease. We examined the functional status of 57 patients who had undergone catheterization (23 men and 34 women), all of whom were told that their hearts were normal, that their pain was noncardiac, and that no limitation on activity was necessary. At a mean follow-up time of 16 +/- 7.7 months, 27 of the 57 patients (47 per cent) still described their activity as limited by chest pain (before catheterization, 42 of 57 or 74 per cent); 29 of 57 (51 per cent) were unable to work (before catheterization, 36 of 57 or 63 per cent); and 25 of 57 (44 per cent) still believed that they had heart disease (before catheterization, 45 of 57 or 79 per cent). Use of medical facilities was significantly reduced after catheterization (P comunication and rehabilitation. PMID:7421961

  4. A Clinical Nurse Specialist-Directed Initiative to Reduce Postoperative Urinary Retention in Spinal Surgery Patients.

    Science.gov (United States)

    Hoke, Nicole; Bradway, Christine

    2016-08-01

    : Postoperative urinary retention (POUR) is the inability to void when the bladder is full after surgery. It is a common complication in postoperative patients, especially in patients undergoing spinal surgery. At our institution, patients who were discharged from the postanesthesia care unit (PACU) to the inpatient surgical unit typically had bladder distention and a bladder volume of more than 450 mL. In an effort to address this situation, an interprofessional group of advanced practice RNs and physicians formed a team, reviewed the existing literature, examined the PACU nursing practice guideline for evaluating and managing POUR, and devised a quality improvement (QI) project to raise the PACU nursing staff's awareness of the potential for POUR among postoperative patients and to develop an updated nursing practice algorithm for the evaluation and management of POUR in spinal surgery patients. A description of the QI process, including the revised algorithm and pre- and postintervention results, is reported here. In the preintervention group (n = 42), 19 indwelling urinary catheterizations were documented in patient records; no use of intermittent catheterization was documented. In the postintervention group (n = 43), seven indwelling urinary catheterizations were documented in patient records; the use of intermittent catheterization was documented in 11. As a result of our intervention, we decreased the number of indwelling urinary catheters inserted in the PACU, and supported the PACU nursing staff in more frequent and appropriate use of intermittent catheterization in patients undergoing spinal surgery.

  5. Transradial approach to cardiovascular interventions: an update.

    Sachdeva, Shilpa; Saha, Sibu

    2014-06-01

    Background Since the first cardiac catheterization in 1929, the procedure has continually evolved with advances in understanding, capabilities, and ease of operation. Though historically performed by cut down of the brachial artery, cardiologists soon learned that transfemoral access was both easier to perform and more efficacious with regard to patient outcome. In the last 20 years, the transradial approach has been adopted, and is being utilized with increasing frequency. Methods We conducted a survey of literature published concerning safety, efficacy, cost-effectiveness, and global uptake of transradial catheterization with specific attention to how transradial interventions compare with transfemoral interventions. Results This review of literature indicates that when performed by an experienced interventionalist, radial catheterization is as effective as femoral catheterization and has additional benefits of shorter length of hospital stay and reduced patient costs. Transradial access is superior to transfemoral access in some, but not all, clinical scenarios; in addition, it is an effective alternative for catheterization in patients contraindicated for transfemoral procedures. Adoption of radial access in the United States is at a faster rate than previously expected, though rate of use varies drastically worldwide. Conclusion The transradial approach is an excellent option for carrying out cardiovascular interventions, and will be adopted by more cardiologists in the upcoming years. PMID:25075159

    Full Text Available Introduction: Percutaneous subclavian vein catheterization is one of the most common invasive procedures performed in cardiac surgery. The aim of this study was to compare left and right subclavian vein catheter placement via the infraclavicular approach in patients who undergo coronary artery bypass graft (CABG surgery.Methods: This prospective, randomized clinical trial was performed in193 patients. The technique applied for cannulation was infraclavicular approach for both the right and the left sides. Subclavian vein of other side was attempted only when catheterization at initial side was unsuccessful at two attempts. The success and complication rates were compared for the two sides.Results: On193 patients, catheterization attempts were performed. 177 catheterizations (91.7% were successful during the first attempt, 105 (92.1% on the right side and 72 (91.1% on the left side. There was no significant difference between success rate and side of catheterization. Malposition of the catheter tip on the right side (9.6% was significantly more than the left side (0% (P= 0.003. The differences in other complications on two sides were statistically insignificant.Conclusion: Compared with the right side, insertion of the cannula on the left side resulted in fewer catheter tip misplacements. Incidence of cannulation failure and other complications were similar on both sides.

Diverticula may be asymptomatic or lead to lower urinary tract symptoms. Rarely, the diverticulum may initially present as a scrotal mass. Case presentation We report the case of a male 45-year-old Arab with paraplegia who presented with a mass in the peno-scrotal junction. He had in his medical history iterative prolonged urethral catheterizations associated with urine leakage through the urethral meatus upon applying compression. Diagnosis confirmation of urethral diverticula is obtained by retrograde urethrography. The patient underwent a diverticulectomy with urethroplasty. Conclusion Male acquired urethral diverticula can be found in patients who have a spinal cord injury because of prolonged urethral catheterization. Clinical presentations are different and sometimes can be misleading. Retrograde urethrography is the key to diagnosis and open surgery is the treatment of reference.

  9. Persistent elevation of neutrophil/lymphocyte ratio associated with new onset atrial fibrillation following percutaneous coronary intervention for acute st segment elevation myocardial infarction

    International Nuclear Information System (INIS)

    Increasing evidence suggests that inflammation plays an important role in initiation and maintaining of atrial fibrillation (AF). The Neutrophil to Lymphocyte (N/L) Ratio is an easily derived and readily available parameter that has emerged as marker of inflammation with predictive and prognostic value. We investigated the association between N/L ratio and incidence of atrial fibrillation in patients undergoing cardiac catheterization for acute ST-segment elevation myocardial infarction (STEMI). Methods: This cross sectional descriptive study was carried out at New York Hospital Queens. We retrospectively analysed clinical, hematologic and angiographic data of 290 patients who underwent coronary angiography with stent placement for acute ST-segment elevation myocardial infarction between 2008-2011. Results: Study cohort of 290 patients had mean age 63.3 ± 13.0 years consisting of 81.4% male. The N/L ratio was measured at time points: <6 hours pre-catheterization, <12, 48 and 96 hours post catheterization. Patients who developed AF (n=40, 13.8%), had higher post catheterization N/L ratios at 48 hours (median 5.23 vs 3.00, p=0.05) and 96 hours (median 4.67 vs 3.56, p=0.03), with no differences in the immediate pre and post procedural measurements, <6 hours pre catheterization (median 2.49 vs 2.82, p=0.467) and <12 hours post catheterization (median 5.93 vs 5.03, p=0.741) respectively. Conclusion: In conclusion, these findings support an inflammatory aetiology contributing to new onset AF following percutaneous coronary intervention for acute STEMI. Further studies are warranted to elucidate these findings. (author)

    @@ Urinary retention is a common urological emergency.Sometimes multi-line tube catheterization is used to treat this urological emergency condition.In this instance, multi-line tube catheterization is considered to be a fast and helpful method, yet it does not treat the root cause.In addition, acupuncture therapy is another unique way used to treat this medical condition, but it is less helpful than the method of thermal acupuncture and massage therapy.therefore, the author used warm needle moxibustion and massage to treat urinary retention-urological emergency, and the report is as follows.

    2014-01-01

    Full Text Available Urethral stricture is a common condition that can lead to serious complications such as urinary infections and renal insufficiency secondary to urinary retention. Treatment options include catheterization, urethroplasty, endoscopic internal urethrotomy, and dilation. Optical internal urethrotomy offers faster recovery, minimal scarring, and less risk of infection, although recurrence is possible. However, technical difficulties associated with poor visualization of the stenosis or of the urethral lumen may increase procedural time and substantially increase the failure rates of internal urethrotomy. In this report we describe a technique for urethral catheterization via a suprapubic, percutaneous approach through the urinary bladder in order to facilitate endoscopic internal urethrotomy.

    Intra-arterial infusion of chemotherapy into the ophthalmic artery for treatment of retinoblastoma has been realized after catheterization of the internal carotid and temporary balloon occlusion beyond the orifice of the ophthalmic artery, or more recently after superselective canulation of the ophthalmic artery by a microcatheter. The superselective catheterization of the ophthalmic artery could be cumbersome because of the implantation of the ostium on the carotid siphon or because of the tortuosity of the carotid siphon. We report our experience of using a retrograde approach through the posterior communicating artery that allows a more direct angle of access to the origin of the ophthalmic artery. (orig.)

  14. The Reten-World survey of the management of acute urinary retention: preliminary results.

    Emberton, Mark; Fitzpatrick, John M

    2008-03-01

    Acute urinary retention (AUR) is a urological emergency characterized by a sudden and painful inability to pass urine. It represents a significant worldwide public health issue, as mortality within the year following an AUR episode appears much higher than in the general population, especially in younger patients. Management of AUR involves immediate bladder catheterization usually followed, until recently, by prostatic surgery. The greater morbidity and mortality associated with emergency surgery (within a few days after AUR), and the potential morbidity associated with prolonged catheterization (bacteriuria, fever, urosepsis) has led to an increasing use of a trial without catheter (TWOC). TWOC involves catheter removal after 1-3 days, allowing 23-40% of patients to void successfully, so that surgery can be performed at a later stage, if needed. Use of an alpha(1)-blocker before a TWOC may also be of help, as it has been demonstrated that it increases the chances of successful voiding after catheter removal. In the UK, this TWOC policy has resulted in a progressive decrease in the number of surgical procedures following a first episode of AUR, with the detriment of a slight increase in the AUR recurrence rate. Currently, there is no consensus on the optimal management of AUR in terms of type of catheterization, duration of catheterization and management following catheterization. The Reten-World survey is aimed at assessing current practice in the management of AUR in France, Asia, Latin America, North Africa and the Middle East. Interim results based on 3785 men with AUR associated with benign prostatic hyperplasia show that a urethral catheter is inserted in most cases (87%). Following this initial step, a TWOC after a median of 3 days' catheterization has become standard practice worldwide, with only a minority of men (6%) undergoing immediate surgery. Treatment with an alpha(1)-blocker before a TWOC improves the chances of success, regardless of the duration

    To reduce the risk of catheter-associated urinary tract infection (CAUTI), limiting use of indwelling catheters is encouraged with alternative collection methods and early removal. Adverse effects associated with such practices have not been described. We also determined if CAUTI preventative measures increase the risk of catheter-related complications. We hypothesized that there are complications associated with early removal of indwelling catheters. We described complications associated with indwelling catheterization and intermittent catheterization, and compared complication rates before and after policy updates changed catheterization practices. We performed retrospective cohort analysis of trauma patients admitted between August 1, 2009, and December 31, 2013 who required indwelling catheter. Associations between catheter days and adverse outcomes such as infection, bladder overdistention injury, recatheterization, urinary retention, and patients discharged with indwelling catheter were evaluated. The incidence of CAUTI and the total number of catheter days pre and post policy change were similar. The incidence rate of urinary retention and associated complications has increased since the policy changed. Practices intended to reduce the CAUTI rate are associated with unintended complications, such as urinary retention. Patient safety and quality improvement programs should monitor all complications associated with urinary catheterization practices, not just those that represent financial penalties. PMID:27657581

    Precise visualization of the pulmonary vasculature is mandatory for adequate treatment of patients with pulmonary atresia and ventricular septal defect (PA-VSD). Aortopulmonary collateral arteries (APCs) can be visualized by selective injections of contrast agent in the catheterization laboratory. To evaluate multidetector CT (MDCT) and different image postprocessing methods for analysis of complex pulmonary blood supply in patients with PA-VSD. Eight patients (6 weeks to 27.8 years of age) with PA-VSD and APCs underwent MDCT and cardiac catheterization. Using multiplanar reformatting, volume rendering and semiautomatic segmentation algorithms, the aorta, pulmonary arteries and APCs were displayed. MDCT and cardiac catheterization were analyzed by two independent observers. MDCT accurately imaged central pulmonary arteries (n=8), aortopulmonary shunts (n=2), right ventricular to pulmonary artery conduits (n=2) and origin, course and intrapulmonary connections of APCs (n=25), compared to X-ray angiography. A high correlation was found between the MDCT vessel diameter measurements by two independent observers (n=70, r=0.96, P<0.01) and between MDCT and angiographic vessel diameter measurements (n=68, r=0.96, P<0.01). Using three-dimensional imaging software, a complex pulmonary blood supply can be non-invasively and accurately imaged with high-resolution MDCT. This technique may help to reduce the number of cardiac catheterizations or guide interventional or surgical therapy. (orig.)

    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.

    2003-01-01

    Objective: To investigate the angiographic characteristics and the interventional catheterization techniques of hepatocellular carcinoma (HCC) fed by aberrant hepatic arteries arising from the superior mesenteric artery (SMA), namely SMA type. Methods: Digital subtraction angiography (DSA) manifes-tations and the data from interventional treatment in 41 cases of SMA type HCCs were retrospectively reviewed. The frequency of the aberrant arteries was summed up statistically and their anatomic charac-teristics (such as origin, course, branches and distribution) and the relationship with catheterization were described and analyzed. Results: Of 350 HCC cases, SMA type HCCs were found in 41 cases (11.9%),including accessory right hepatic artery (15 cases, 36.5%), replaced right hepatic artery (16 cases, 39.0%),common hepatic artery (8 cases, 19.5%) and celiac artery arising from SMA (2 cases, 5.0%). Of the 31 cases with accessory or replaced right hepatic arteries, right hepatic arteries were small or absent on celiac angiograph in 29 cases (94.0%), and there was an avascular zone on the right liver. Superselective catheter-ization was successfully performed in 25 cases (61%) by using RH catheter, but the rest acquired successful superselective catheterization by using Cobra, Simmon catheters and microcatheters. Conclusion: SMA type is a commonly seen variation of hepatic arterial blood supply. A knowledge of this is very important in transcatheter arterial chemoembolization for HCC.

    Background In 1981, Mitrofanoff described a procedure to create a continent urinary stoma for clean intermittent catheterization. Since then several procedures have been described including Yang-Monti ileovesicostomy for effective catheterization. Objectives We report on our experience from the use of Monti’s procedure in children at our center. Patients and Methods Children Monti’s procedure for congenital conditions or neuropathic bladder formed the study group. All these children, post-operatively were taught clean intermittent catheterization (CIC) and put on a regime using a 14/16 Fr catheter every 3 hours. The children were followed regularly at 3, 6, 12, 18 and 24months post-operatively, with special attention paid to any problems with catheterization and incontinence. Results During the period from Jan 2000 to Dec 2011, at our center, 19 children less than eighteen years of age underwent urinary diversion with Yang-Monti’s catheterizable stoma. The indications for urinary diversion was neuropathic bladder in eight, exstrophy bladder in seven , valve bladder syndrome in three and persistent urethral stricture in one. None of the children found CIC difficult during the post-operative period and there was no hindrance to the passage of the catheter. Conclusions Although the appendix remains the tissue of choice for creation of catherterizable stoma, the Yang-Monti ileovesicostomy is effective, convenient conduit for children. Long-term complications are minimal and children find this comfortable to do CIC. PMID:24282789

  12. Percutaneous Treatment of Splenic Cystic Echinococcosis: Results of 12 Cases

    International Nuclear Information System (INIS)

    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

    Full Text Available Introduction: The aim of this study was to present the incidence of the vascular complications that had to be surgically treated during the two-year period of transfemoral cardiac catheterization procedure and to identify the risk factors associated with the complications.Methods: A retrospective two-year study of post-catheterization complications with the six-month postoperative follow-up and analysis of risk factors was done. Patients with cardiovascular diseases who underwent therapeutic or diagnostic coronary angiography in the period of 2012-2013 were included in the study. A total of 1320 patients were subjected to catheterization for coronary angiography, of which 24 had vascular complications that had to be surgically treated. Indications for operative treatment included rapid growth of pseudoaneurysm, hemorrhage, large hematoma, hemodynamic instability, failure of the targeted compression therapy.Results: Twenty-four patients experienced some kind of post-operative complication. Infection and dehiscence of surgical wound were the two most common complications. There were no fatalities. The average length of a hospitalization was 4 days. The important risk factors are gender (women more than man, obesity, concomitant use of anticoagulation therapy and antiplatelet therapy after catheterization.Conclusion: Insufficient length of the compression of the punctured place and increased risks of a pseudoaneurysm formation, such as female gender, obesity, and use of a combined anticoagulant therapy are the main causes of these complications. Late vascular complications are not uncommon.

    Fifty-two patients undergoing cardiac catheterization and subsequently found to have significant coronary artery disease (CAD) were given structured psychiatric interviews before catheterization. Nine of these patients met criteria for major depressive disorder. All 52 patients were contacted 12 months after catheterization, and the occurrence of myocardial infarction, angioplasty, coronary bypass surgery and death was determined. Results of the study show that major depressive disorder was the best predictor of these major cardiac events during the 12 months following catheterization. The predictive effect was independent of the severity of CAD, left ventricular ejection fraction, and the presence of smoking. Furthermore, with the exception of smoking, there were no statistically significant differences between those patients with major depressive disorder and the remaining patients on any variable studied. The possible mechanisms relating major depressive disorder to subsequent cardiac events are discussed. It is concluded that major depressive disorder is an important independent risk factor for the occurrence of major cardiac events in patients with CAD. PMID:2976950

    Full Text Available Proteus mirabilis strains ability to form biofilm is a current topic of a number of research worldwide. In this study the biofilm formation of P. mirabilis strains derived from urine of the catheterized and non-catheterized patients has been investigated. A total number of 39 P. mirabilis strains isolated from the urine samples of the patients of dr Antoni Jurasz University Hospital No. 1 in Bydgoszcz clinics between 2011 and 2012 was used. Biofilm formation was evaluated using two independent quantitative and qualitative methods with TTC (2,3,5-triphenyl-tetrazolium chloride and CV (crystal violet application. The obtained results confirmed biofilm formation by all the examined strains, except quantitative method with TTC, in which 7.7% of the strains did not have this ability. It was shown that P. mirabilis rods have the ability to form biofilm on the surfaces of both biomaterials applied, polystyrene and polyvinyl chloride (Nelaton catheters. The differences in ability to form biofilm observed between P. mirabilis strains derived from the urine of the catheterized and non-catheterized patients were not statistically significant.

    Full Text Available OBJECTIVE: To evaluate the role of right heart catheterization in the diagnosis of pulmonary arterial hypertension (PAH. METHODS: We evaluated clinical, functional, and hemodynamic data from all patients who underwent right heart catheterization because of diagnostic suspicion of PAH-in the absence of severe left ventricular dysfunction (LVD, significant changes in pulmonary function tests, and ventilation/perfusion lung scintigraphy findings consistent with chronic pulmonary thromboembolism-between 2008 and 2013 at our facility. RESULTS: During the study period, 384 patients underwent diagnostic cardiac catheterization at our facility. Pulmonary hypertension (PH was confirmed in 302 patients (78.6%. The mean age of those patients was 48.7 years. The patients without PH showed better hemodynamic profiles and lower levels of B-type natriuretic peptide. Nevertheless, 13.8% of the patients without PH were categorized as New York Heart Association functional class III or IV. Of the 218 patients who met the inclusion criteria, 40 (18.3% and 178 (81.7% were diagnosed with PH associated with LVD (PH-LVD and with PAH, respectively. The patients in the HP-LVD group were significantly older than were those in the PAH group (p < 0.0001. CONCLUSIONS: The proportional difference between the PAH and PH-LVD groups was quite significant, considering the absence of echocardiographic signs suggestive of severe LVD during the pre-catheterization investigation. Our results highlight the fundamental role of cardiac catheterization in the diagnosis of PAH, especially in older patients, in whom the prevalence of LVD that has gone undiagnosed by non-invasive tests is particularly relevant.

    Full Text Available Background: The optimal bladder management method should preserve renal function and minimize the risk of urinary tract complications. The present study is conducted to assess the overall incidence of urinary tract infections (UTI and other urological complications in spinal cord injury patients (SCI, and to compare the incidence of these complications with different bladder management subgroups. Materials and Methods: 545 patients (386 males and 159 females of traumatic spinal cord injury with the mean age of 35.4±16.2 years (range, 18 - 73 years were included in the study. The data regarding demography, bladder type, method of bladder management, and urological complications, were recorded. Bladder management methods included indwelling catheterization in 224 cases, clean intermittent catheterization (CIC in 180 cases, condom drainage in 45 cases, suprapubic cystostomy in 24 cases, reflex voiding in 32 cases, and normal voiding in 40 cases. We assessed the incidence of UTI and bacteriuria as the number of episodes per hundred person-days, and other urological complications as percentages. Results: The overall incidence of bacteriuria was 1.70 / hundred person-days. The overall incidenceof urinary tract infection was 0.64 / hundered person-days. The incidence of UTI per 100 person-days was 2.68 for indwelling catheterization, 0.34 for CIC, 0.34 for condom drainage, 0.56 for suprapubic cystostomy, 0.34 for reflex voiding, and 0.32 for normal voiding. Other urological complications recorded were urethral stricture (n=66, 12.1%, urethritis (n=78, 14.3%, periurethral abscess (n=45, 8.2%, epididymorchitis (n=44, 8.07%, urethral false passage (n=22, 4.03%, urethral fistula (n=11, 2%, lithiasis (n=23, 4.2%, hematuria (n=44, 8.07%, stress incontinence (n=60, 11%, and pyelonephritis (n=6, 1.1%. Clean intermittent catheterization was associated with lower incidence of urological complications, in comparison to indwelling catheterization. Conclusions

    Isolated coarctation of the aorta (CoA) occurs in 6-8 % of patients with congenital heart disease. After successful relief of obstruction, patients remain at risk for aortic aneurysm formation at the site of the repair. We sought to determine the diagnostic utility of echocardiography compared with advanced arch imaging (AAI) in diagnosing aortic aneurysms in pediatric patients after CoA repair. The Congenital Heart Databases from 1996 and 2009 were reviewed. All patients treated for CoA who had AAI defined by cardiac magnetic resonance imaging (MRI), computed tomography (CT), or catheterization were identified. Data collected included the following: type, timing, and number of interventions, presence and time to aneurysm diagnosis, and mortality. Patients were subdivided into surgical and catheterization groups for analysis. Seven hundred and fifty-nine patients underwent treatment for CoA during the study period. Three hundred and ninety-nine patients had at least one AAI. Aneurysms were diagnosed by AAI in 28 of 399 patients at a mean of 10 ± 8.4 years after treatment. Echocardiography reports were available for 380 of 399 patients with AAI. The sensitivity of echocardiography for detecting aneurysms was 24 %. The prevalence of aneurysms was significantly greater in the catheterization group (p Aneurysm was also diagnosed earlier in the catheterization group compared with the surgery group (p = 0.02). Multivariate analysis showed a significantly increased risk of aneurysm diagnosis in patients in the catheterization subgroup and in patients requiring more than three procedures. Aortic aneurysms continue to be an important complication after CoA repair. Although serial echocardiograms are the test of choice for following-up most congenital cardiac lesions in pediatrics, our data show that echocardiography is inadequate for the detection of aneurysms after CoA repair. Because the time to aneurysm diagnosis was shorter and the risk greater in the

    Background Guidelines for triaging patients for cardiac catheterization recommend a risk assessment and noninvasive testing. We determined patterns of noninvasive testing and the diagnostic yield of catheterization among patients with suspected coronary artery disease in a contemporary national sample. Methods From January 2004 through April 2008, at 663 hospitals in the American College of Cardiology National Cardiovascular Data Registry, we identified patients without known coronary artery disease who were undergoing elective catheterization. The patients’ demographic characteristics, risk factors, and symptoms and the results of noninvasive testing were correlated with the presence of obstructive coronary artery disease, which was defined as stenosis of 50% or more of the diameter of the left main coronary artery or stenosis of 70% or more of the diameter of a major epicardial vessel. Results A total of 398,978 patients were included in the study. The median age was 61 years; 52.7% of the patients were men, 26.0% had diabetes, and 69.6% had hypertension. Noninvasive testing was performed in 83.9% of the patients. At catheterization, 149,739 patients (37.6%) had obstructive coronary artery disease. No coronary artery disease (defined as <20% stenosis in all vessels) was reported in 39.2% of the patients. Independent predictors of obstructive coronary artery disease included male sex (odds ratio, 2.70; 95% confidence interval [CI], 2.64 to 2.76), older age (odds ratio per 5-year increment, 1.29; 95% CI, 1.28 to 1.30), presence of insulin-dependent diabetes (odds ratio, 2.14; 95% CI, 2.07 to 2.21), and presence of dyslipidemia (odds ratio, 1.62; 95% CI, 1.57 to 1.67). Patients with a positive result on a noninvasive test were moderately more likely to have obstructive coronary artery disease than those who did not undergo any testing (41.0% vs. 35.0%; P<0.001; adjusted odds ratio, 1.28; 95% CI, 1.19 to 1.37).

  9. Occupational exposures from selected interventional radiological procedures

    International Nuclear Information System (INIS)

    The number of radiology and cardiology interventional procedures has significantly increased in recent years due to better diagnostic equipment resulting in an increase in radiation dose to the staff and patients. The assessment of staff doses was performed for cardiac catheterization and for three other non-cardiac procedures. The scattered radiation distribution resulting from the cardiac catheterization procedure was measured prior to the staff dose measurements. Staff dose measurements included those of the left shoulder, eye, thyroid and hand doses of the cardiologist. In non-cardiac procedures doses to the hands of the radiologist were measured for nephrostomy, fistulogram and percutaneous transluminal angioplasty procedures. Doses to the radiologist or cardiologist were found to be relatively high if correct protection was not observed. (author)

We report a case of severe bleeding in a 37-year-old man resulting from celiac trunk stretching after a motorcycle crash. Because direct celiac trunk catheterization was not possible, a retrograde catheterization of the common hepatic artery was performed via the superior mesenteric artery. Two vascular plugs (type IV) were released, and the exclusion of the celiac trunk origin was completed with the deployment of an aortic cuff. The patient's clinical condition immediately improved, and after 6 months' follow-up, imaging confirmed the complete exclusion of the celiac trunk.

    Since urethral Foley catheterization is usually easy and safe, serious complications related to this procedure have been rarely reported. Herein, we describe a case of intraperitoneally placed urethral catheter via verumontanum presenting as intraperitoneal bladder perforation in a chronically debilitated elderly patient. A 82-yr-old male patient was admitted with symptoms of hematuria, lower abdominal pain after traumatic Foley catheterization. The retrograde cystography showed findings of intraperitoneal bladder perforation, but emergency laparotomy with intraoperative urethrocystoscopy revealed a tunnel-like false passage extending from the verumontanum into the rectovesical pouch between the posterior wall of the bladder and the anterior wall of the rectum with no bladder injury. The patient was treated with simple closure of the perforated rectovesical pouch and a placement of suprapubic cystostomy tube. PMID:21935283

    Full Text Available Occlusions of major vessels in patients with congenital heart disease may occur due to a variety of factors. These occlusions are often felt to be best addressed surgically; however, we and others have been successful in recanalizing most of these vessels in the catheterization laboratory. Most of these patients will require multiple procedures in the catheterization laboratory to ensure vessel patency and to facilitate vessel growth. Physicians performing the procedure should have a thorough understanding of the anatomic considerations for the intended procedure and have access to a variety of devices and equipment to optimize the result of the procedure. In this article, we review some of the technical aspects that are vital for the success of the procedure.

  16. Uterine arterial chemoembolization combined with curettage for the treatment of cesarean scar pregnancy

    International Nuclear Information System (INIS)

    Objective: To evaluate uterine arterial chemoembolization combined with curettage in treating cesarean scar pregnancy. Methods: Super-selective bilateral uterine arterial catheterization and angiography was performed in 64 patients with cesarean scar pregnancy (duration of amenorrhea 43-84 days), which was followed by arterial infusion of MTX and embolization with Gelfoam particles. Then curettage was carried out. The technical success rate and the therapeutic results were observed and analyzed. Results: Technical success in catheterization and in performing chemoembolization was achieved in all 64 patients. The pregnant tissues were successfully cleared away in 62 patients. The average blood loss during curettage procedure was 21.4 ml. For the remaining two patients lesion resection together with repair of lower segment was employed. No severe complications occurred after the treatment. Conclusion: Uterine arterial chemoembolization combined with curettage is a safe,minimally-invasive and effective treatment for cesarean scar pregnancy. It is worth popularizing this technique in clinical practice. (authors)

    A study was undertaken to assess the efficacy and safety of femoral venous catheterization for resuscitation of critically ill patients in the emergency department setting. From May 1982 to April 1983, 100 attempts were made at percutaneous insertion of a large-bore catheter into the femoral veins of patients presenting to our emergency department in cardiac arrest or requiring rapid fluid resuscitation. Eighty-nine attempts were successful. Insertion was generally considered easy, and flow rates were excellent. The only noted complications were four arterial punctures and one minor groin hematoma. This study suggests that short-term percutaneous catheterization of the femoral vein provides rapid, safe, and effective intravenous access. PMID:6703430

    2003-01-01

    Objective: To explore the risk factors of nosocomial infection in severe craniocerebral trauma and the way of prevention.Methods: The clinical data of 387 patients with severe craniocerebral trauma were reviewed.Results: The total nosocomial infection rate of this study was 22.99%. Pulmonary nosocomial infection presented most frequently. The G-bacilli were the most common infectious bacteria. The mortality rate of the infection group was 38.20%.Conclusions: Complications of nosocomial infection affect the prognosis of craniocerebral trauma patients. Nosocomial infection is related to the age of the patients, craniocerebral trauma severity, unreasonable utilization of antibiotics and invasive operations, such as tracheal cannula, mechanical ventilation, urethral catheterization and deep venous catheterization. Patients with severe craniocerebral trauma should be carefully treated and nursed to avoid nosocomial infection. In order to reduce the rate of nosocomial infection, intensive measurement should be adopted.

  19. Clinical course of cor pulmonale investigated after an interval of one year by thallium-201 myocardial SPECT scintigraphy

    International Nuclear Information System (INIS)

    Cor pulmonale was evaluated in 13 patients with chronic lung disease by thallium-201 myocardial SPECT scintigraphy together with pulmonary function tests and right heart catheterization. One year later, we performed this scintigraphy again to investigate the clinical course of the cor pulmonale. In 6 of 13 patients with respiratory failure (Pao2 less than 60 Torr), a remarkable progression in cor pulmonale was noted after one year, despite outpatient oxygen therapy. If the patients were admitted because of acute exacerbation of respiratory failure, the cor pulmonale was found to have worsened. In contrast, patients with acute exacerbation due to respiratory infection or causes other than respiratory failure, showed little change in cor pulmonale. Although patients with a marked progression of cor pulmonale tended to have poor pulmonary function data and elevated pulmonary arterial pressure, the clinical course of cor pulmonale could not be predicted from the initial pulmonary function tests or right heart catheterization.

    2016-01-01

    Recently, the use of paravertebral block (PVB) during thoracic surgery has been re-evaluated, as it is not inferior to epidural anaesthesia for postoperative pain control, and has been associated with fewer complications (e.g., hematoma of epidural, hypotension, urinary retention, postoperative nausea and vomiting). No reports have described intraoperative catheterization for PVB during single-incision thoracoscopic surgery (SITS) as distinct from thoracotomy or multi-ports video-assisted thoracoscopic surgery. We describe a case of SITS bullectomy using a chest wall pulley for lung excision to treat primary spontaneous pneumothorax and 25 catheterizations for PVB during SITS that have been performed since June 2013. Our novel technique is both easy and safe. It is ideal to combine PVB with SITS because both methods are less invasive. PMID:26346002

    The prevalence of urinary complications after various anorectal operations was studied in a group of 273 patients. The overall prevalence of urinary complications was 26.7%; most of these complications affected men between 41 and 50, mainly after hemorrhoidectomy. In 10.6% of patients, bladder catheterization was needed. These urinary complications result from nervous reflexes originating from the anus and determined by the operative trauma and/or rectal distinction. In the treatment of these urinary complications, the role of the muses is essential for reassuring the patients. Parasympathomimetic drugs are often efficient. Urinary catheterization must be delayed until the 18th hour. Fluid restriction may be useful to prevent urinary retention. PMID:14870531

    Butreau-Lemaire, M; Botto, H

    1997-09-01

    The concept of nosocomial urinary tract infection now corresponds to a precise definition. It is generally related to bladder catheterization, constitutes the most frequent form of nosocomial infection (30 to 50% of infections), and represents the third most frequent portal of entry of bacteraemia. The organism most frequently isolated is Escherichia coli; but the flora is changing and the ecological distribution is continually modified. Despite their usually benign nature, these nosocomial infections can nevertheless influence hospital mortality; they increase the hospital stay by an average of 2.5 days and their treatment represents a large share of the antibiotic budget. Prevention of these infections is therefore essential, with particular emphasis on simple and universally accessible measures: very precise indications for vesical catheterization, use of closed circuit drainage, maximal asepsis when handling catheters, after washing the hands.

    Full Text Available In the United States, duloxetine has been approved for the treatment of major depressive disorder, diabetic peripheral neuropathic pain and fibromyalgia in the adult population. Data regarding the use of duloxetine in the pediatric population, however, are very limited. Femoral nerve injury is a rare complication of cardiac catheterization. In the case described, duloxetine contributed to a successful multimodal treatment program for peripheral neuropathic pain due to femoral neuropathy in an adolescent with ‘reactive depression’ and conversion symptoms. To the best of the authors’ knowledge, the present article is only the third such report on this dual use of duloxetine in children and adolescents, and the first report of such treatment following femoral neuropathy induced by cardiac catheterization.

    Dextrocardia is a rare congenital anomaly with a prevalence of 1 in 10,000 births. The incidence of coronary artery disease in such patients is thought to be similar to that of the general public, however, patients are seldom seen during routine clinical practice and at the cardiac catheterization laboratory. Patients with this condition and acute myocardial ischemia may pose challenges at presentation, clinical and diagnostic findings and at cardiac catheterization. In this report, a male patient presenting with acute inferior myocardial infarction and three-vessel coronary artery disease was managed successfully with emergency primary angioplasty and later elective multivessel stenting. This is the first combined primary and later multivessel stenting to be reported in a single patient with dextrocardia and situs inversus. The clinical findings, details of the procedures and literature review will be discussed.

    @@ Drs. Rigatem, Rigatelli, and Trivellato present a complete retrospective review of the prevalence of congenital coronary abnormalities in a cohort of consecutive adult patients catheterized at their institution and compare them to younger patients < 65 years of age.They review in detail the clinical implications of these findings and then offer an algorithm for management. This article is particularly timely and significant as we move into an era of non-invasive coronary imaging with CT,MRI, and improved echo that will allow ns to make these diagnoses more often and with greater accuracy in younger patients. This will have a significant impact on the nanagement of symptomatic patients diagnosed at catheterization but also on asymptomatic patients diagnosed on screening evaluations.

  7. Hemoperitoneum in a peritoneal dialysis patient from a retroperitoneal source.

    Balsera, Cristina; Guest, Steven

    2013-01-01

    Hemoperitoneum in peritoneal dialysis patients is a known but infrequent complication. Hemoperitoneum is more frequent in women because of its association with a variety of gynecologic presentations such as reflux menstruation, ovulation, endometrial tissue implants within the peritoneal cavity (endometriosis), and bleeding follicular cysts. Other intraperitoneal causes of hemoperitoneum include minor catheter or abdominal trauma, vascular anomalies, or hepatic or splenic cysts. Less frequently encountered is a presentation of hemoperitoneum from a retroperitoneal source. These presentations result either from peritoneal inflammation and subsequent peritoneal bleeding or retroperitoneal cavity pathology rupturing into the peritoneal cavity. Here, we present the case of a peritoneal dialysis patient presenting with hemoperitoneum several days after undergoing cardiac catheterization. The catheterization was complicated by a large retroperitoneal hematoma. Details of the case are reported, and other retroperitoneal causes of hemoperitoneum are reviewed.

    Ureteroarterial fistulas (UAFs) are defined as an abnormal communication between one of the major arteries and the ureter. Urologists most frequently encounter iatrogenic fistulas occurring in patients with a history of pelvic extirpative surgery, chronic ureteral catheterization, and history of pelvic radiation. We present two cases of UAFs in patients with no history of prior radiation, who underwent open radical cystectomy and robot-assisted radical cystectomy with intracorporeal ileal conduit. Both patients developed postoperative ureteroileal anastomotic leaks that were managed with indwelling ureteral catheters. Furthermore, both patients were having left-sided UAF after presenting with nonlife threatening gross hematuria, which became brisk and pulsatile during ureteral stent exchange. Endovascular stenting was performed in both patients with resolution of hemorrhage and full recovery. In one patient, nephrostomy tubes were placed and ureteral catheters were removed; the second patient was managed with continued ureteral catheterization without further episodes of hematuria.

    Subcutaneous adipose tissue lipolysis was studied in vivo by Fick's arteriovenous (a-v) principle using either calculated (microdialysis) or directly measured (catheterization) adipose tissue venous glycerol concentration. We compared results during steady-state (rest and prolonged continuous...... exercise), as well as during non-steady-state (onset of exercise and early exercise) experimental settings. Fourteen healthy women [age: 74 +/- 1 (SE) yr] were studied at rest and during 60-min continuous bicycling at 60% of peak O(2) uptake. Calculated and measured subcutaneous abdominal adipose tissue...... adipose tissue venous glycerol concentration. Despite several methodological limitations inherent to both techniques, the results strongly suggest that microdialysis and catheterization provide similar estimates of subcutaneous adipose tissue lipolysis in steady-state experimental settings like rest...

  10. Loss of Guide Wire: A Rare Complication of Intra-Aortic Balloon Pump Insertion

    2015-10-01

    Full Text Available At the final stages of a coronary artery bypass graft operation on a 64-year-old man, an experienced physician attempted to insert an intra-aortic balloon pump into the femoral artery via the Seldinger technique. However, while the balloon pump was being passed over the guide wire, the latter was completely lost.The guide wire should be held at the tip at all times to prevent passage into the vessel. Strict adherence to this rule will prevent guide-wire loss, which is, albeit rare and completely avoidable, a potentially life-threatening complication of central vein or artery catheterization, with reported fatality rates of up to 20% when the whole wire is lost. The literature contains several reports on guide-wire loss during central venous, arterial, and hemodialysis catheterization, but we report for the first time the loss of a guide wire as a rare complication of intra-aortic balloon pump insertion.

    Full Text Available The bases and technical cares for the neuro-radiological study of the aorto-cervical and spinal vessels employing the retrograde catheterization according to Seldinger technic and with the Odman-Ledin catheters are reported. The authors recommend type II neuroleptanalgesia as anesthesical sedative and the use of percutaneous punction of the femoral artery or, by choice, of the axilar or humeral artery. For the selective catheterization by femoral via, they make previously an aortography, in order to know the anatomy of the supra-aortic vessels, with control through the image-inten-sifier or fluoroscopy. They employ manual injection for the study of the supra-aortic vessels and a Gidlung injector for the contrast of the ascending aorta. Complications are discussed.

    Subclavian artery pseudoaneurysm that induced from central venous catheterization through the internal jugular vein is relatively uncommon. However, the management of subclavian artery pseudoaneurysm remains a challenge because of their non-compressibility of deep locality and relationship to important surrounding anatomy, such as the origin of vertebral artery. In this paper, the authors report a patient with larger iatrogenic subclavian arterial pseudoaneurysm near the origin of vertebral artery, that was treated successfully by endovascular covered stent and coils.

    In the Ticlid or Plavix Post-Stents (TOPPS) trial, 1016 patients undergoing successful coronary stent placement were randomized to receive aspirin and either ticlopidine or clopidogrel. In this trial, the dosages and regimens of ticlopidine and clopidogrel resembled more closely those used in most catheterization laboratories than did the two previous randomized trials comparing ticlopidine and clopidogrel. The results of the TOPPS trial support the current practice of substituting ticlopidine for clopidogrel in stent patients.

    Hyperglycemia in the hospitalized setting is common, especially in patients that receive nutritional support either continuously or intermittently. As the liver and muscle are the major sites of glucose disposal, we hypothesized their metabolic adaptations are sensitive to the pattern of nutrient delivery. Chronically catheterized, well-controlled depancreatized dogs were placed on one of three isocaloric diets: regular chow diet once daily (Chow) or a simple nutrient diet (ND) that was given...

    The transmastoid branch of the occipital artery is an important supply to posterior fossa vascular malformations and tumors and is often difficult to catheterize due to tortuosity and a transforaminal course. In very difficult situations, we can try to induce spasm of the occipital artery just beyond the origin of the mastoid branch by repeated passages of the microcatheter/wire. This induces a temporary ‘ligation’ like effect so that the microcatheter can then be manipulated into the mastoid...

    Right ventricular failure (RVF) is an underestimated problem in intensive care. This review explores the physiology and pathophysiology of right ventricular function and the pulmonary circulation. When RVF is secondary to an acute increase in afterload, the picture is one of acute cor pulmonale, as occurs in the context of acute respiratory distress syndrome, pulmonary embolism and sepsis. RVF can also be caused by right myocardial dysfunction. Pulmonary arterial catheterization and echocardi...

    We report a rare, but serious, complication of a malpositioned umbilical venous catheter in a term male infant who developed laceration, hematoma, and necrosis of liver, ascites, and left-sided obstructive uropathy secondary to extravasation of total parenteral nutrition. Abdominal paracentesis confirmed the presence of parenteral nutrition in the peritoneal cavity. Although, the umbilical venous catheterization is a common intravenous access used in neonatal intensive care units, judicious continued monitoring of its use should be practiced to avoid serious complications.

    Sparklines, embedded contextual information graphics, can help reduce diagnostic errors by highlighting trends in data, simplifying cognitive tasks and providing context for decision making. Examples applied to heparin induced thrombocytopenia, cardiac catheterization and pediatric viral illness illustrate the concept. Sparklines are ideal in situations where the limited textual data representations obfuscate interpretation, the graphic aids interpretation of the data, or the graphic guides decision making.

    Introduction: The Foley catheter has been widely assumed to be an effective means of draining the bladder. However, recent studies have brought into question its efficacy. The objective of our study is to further assess the adequacy of Foley catheter for complete drainage of the bladder. Materials and Methods: Consecutive catheterized patients were identified from a retrospective review of contrast enhanced and non-contrast enhanced computed tomographic (CT) abdomen and pelvis studies completed from 7/1/2011-6/30/2012. Residual urine volume (RUV) was measured using 5mm axial CT sections as follows: The length (L) and width (W) of the bladder in the section with the greatest cross sectional area was combined with bladder height (H) as determined by multiplanar reformatted images in order to calculate RUV by applying the formula for the volume (V) of a sphere in a cube:V=(π/6)⁎L⁎W⁎H). Results: RUVs of 167 (mean age 67) consecutively catheterized men (n=72) and women (n=95) identified by CT abdomen and pelvis studies were calculated. The mean RUV was 13.2 mL (range: 0.0 mL-859.1 mL, standard deviation: 75.9 mL, margin of error at 95% confidence:11.6 mL). Four (2.4%) catheterized patients had RUVs of >50 mL, two of whom had an improperly placed catheter tip noted on their CT-reports. Conclusions: Previous studies have shown that up to 43% of catheterized patients had a RUV greater than 50 mL, suggesting inadequacy of bladder drainage via the Foley catheter. Our study indicated that the vast majority of patients with Foley catheters (97.6%), had adequately drained bladders with volumes of <50 mL. (author)

    The past decade has witnessed significant developments in the use of catheter-based therapies in cardiovascular medicine. We sought to assess the educational opportunities for cardiac surgery trainees to determine their readiness for participation in these strategies. A web-based survey was distributed to current residents, recent graduates, and program directors in Canadian cardiac surgery residency programs from 2008-2013. The survey was distributed to 110 residents and graduates. Forty-five percent completed the survey. Thirty-five percent expressed that they experienced resistance organizing their rotations because they had to compete with non-cardiac surgery colleagues, and 6 were denied local cardiac catheterization rotations. By the end of the rotation, 56% were comfortable performing a diagnostic cardiac catheterization independently. Exposure to being the operator performing diagnostic catheterization was significantly associated with the positive perception of being able to perform a diagnostic catheterization independently (odds ratio [OR], 5.14; 95% confidence interval [CI], 1.33-19.81; P = 0.017). Eighty-eight percent of respondents expressed the need for more exposure in catheter-based rotations. Seven of 11 program directors completed the survey. All believed such rotations should be mandatory and foresaw a bigger role for hybrid catheter-based/cardiac surgery procedures in the future. Trainees and program directors perceive that increased exposure to catheter-based therapies is important to career development as a cardiac surgeon. This survey will contribute to the development of a cardiac surgery training curriculum as we foresee more hybrid and team procedures.

    Urethral condyloma is a therapeutic challenge. This article reports the case of a patient with spinal cord injury with the incidental finding of a massive spread of urethral condyloma. After removal of the condyloma with biopsy forceps neither recurrence of the condyloma nor a urethral stricture occurred. In patients where intermittent catheterization is performed, condyloma may be dispersed into the bladder, therefore, prompt endoscopic removal is crucial. As condyloma frequently recurs even after complete removal regular controls are mandatory. PMID:22801816

    AMP-activated protein kinase (AMPK) has been postulated as a super-metabolic regulator, thought to exert numerous effects on skeletal muscle function, metabolism, and enzymatic signaling. Despite these assertions, little is known regarding the direct role(s) of AMPK in vivo, and results obtained in vitro or in situ are conflicting. Using a chronically catheterized mouse model (carotid artery and jugular vein), we show that AMPK regulates skeletal muscle metabolism in vivo at several levels, w...
