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

    Acute kidney injury (AKI) complicating percutaneous coronary intervention (PCI) is associated with adverse clinical outcomes. To date, no studies have evaluated the association of blood transfusion with AKI in patients undergoing PCI. We used a retrospective cohort study of all patients with acute coronary syndrome undergoing PCI from CathPCI Registry (n=1 756 864). The primary outcome was AKI defined as the rise in serum creatinine post procedure ≥0.5 mg/dL or ≥25% above baseline values. AKI developed in 9.0% of study sample. Patients with AKI were older, more often women, and had high prevalence of comorbidities, including diabetes mellitus, hypertension, and advanced stages of chronic kidney disease at baseline. Blood transfusion was utilized in 2.2% of patients. In the overall sample, AKI developed in 35.1% of patients who received transfusion versus 8.4% of patients without transfusion (adjusted odds ratio, 4.87 [4.71-5.04]). In the subgroup of patients who sustained bleeding event and received transfusion, the rate of AKI was significantly increased across all preprocedure hemoglobin levels versus no blood transfusion. Similar findings were seen in the subgroup of patients with no bleeding event. Blood transfusion is strongly associated with AKI in patients with acute coronary syndrome undergoing PCI. Further investigation is needed to determine whether a restrictive blood transfusion strategy might improve PCI outcomes by reducing the risk of AKI. © 2016 American Heart Association, Inc.

    Few data exist on temporal evolution of antithrombotic agent use in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI) in Italy. We sought to compare data from the most recent prospective, multicenter, nationwide registries conducted in Italy, namely EYESHOT and SCOPE. EYESHOT enrolled 2585 consecutive ACS patients, both ST-segment elevation myocardial infarction (STEMI) and non-ST elevation ACS (NSTE-ACS), admitted to 203 Italian coronary care units over a 3-week period (2-22 Dec 2013 and 27 Jan-16 Feb 2014). Among patients enrolled in EYESHOT, 1755 (67.9%) underwent PCI (52.6% with STEMI and 47.4% with NSTE-ACS). In the SCOPE registry, a total of 1363 patients undergoing PCI were enrolled over 3 months (15 Feb-15 Apr 2016) in 39 Italian cath lab centers at medium to high PCI volume: 331 (24.3%) with a diagnosis of STEMI and 1032 (75.7%) with a diagnosis of NSTE-ACS. Over 2 years, the use of clopidogrel in the cath lab significantly decreased (from 11% to 8% in STEMI; p=0.06 and from 9% to 5% in NSTE-ACS; p=0.0002), while the administration of ticagrelor dramatically increased (from 14% to 37%; pSCOPE registries, a significant increase in the use of novel P2Y12 receptor inhibitors was observed, both at the time of PCI and at discharge.

    We sought to determine the frequency of use and association between prasugrel and outcomes in acute coronary syndrome patients undergoing percutaneous coronary intervention (PCI) in clinical practice. PROMETHEUS was a multicenter observational registry of acute coronary syndrome patients undergoing PCI from 8 centers in the United States that maintained a prospective PCI registry for patient outcomes. The primary end points were major adverse cardiovascular events at 90days, a composite of all-cause death, nonfatal myocardial infarction, stroke, or unplanned revascularization. Major bleeding was defined as any bleeding requiring hospitalization or blood transfusion. Hazard ratios (HRs) were generated using multivariable Cox regression and stratified by the propensity to treat with prasugrel. Of 19,914 patients (mean age 64.4years, 32% female), 4,058 received prasugrel (20%) and 15,856 received clopidogrel (80%). Prasugrel-treated patients were younger with fewer comorbid risk factors compared with their counterparts receiving clopidogrel. At 90days, there was a significant association between prasugrel use and lower major adverse cardiovascular event (5.7% vs 9.6%, HR 0.58, 95% CI 0.50-0.67, P<.0001) and bleeding (1.9% vs 2.9%, HR 0.65, 95% CI 0.51-0.83, P<.001). After propensity stratification, associations were attenuated and no longer significant for either outcome. Results remained consistent using different approaches to adjusting for potential confounders. In contemporary clinical practice, patients receiving prasugrel tend to have a lower-risk profile compared with those receiving clopidogrel. The lower ischemic and bleeding events associated with prasugrel use were no longer evident after accounting for these baseline differences. Copyright © 2017 Elsevier Inc. All rights reserved.

    To investigate the association of renal insufficiency and clinical outcomes in patients with acute coronary syndrome(ACS). The study was a multi-centre register study including 3,589 ACS patients coming from 39 centers across China who had received percutaneous coronary intervention(PCI) prior to 1st February, 2007. Estimated glomerular filtration rate (eGFR) was calculated for all patients using the 4-variable MDRD equation with the serum creatinine obtained before angiography. The association between renal insufficiency and clinical outcomes and the presence of in-hospital death and bleeding was studied by Fisher's exact test. Multi-variable analysis on the risk factors of in-hospital bleeding was done by logistic regression test. The mean age of the study population was (61.74+/-11.37) years (ranging from 23 years to 92 years)and 76.5% (2,746/3,589) of the population was male. Only 90 patients (2.51%) were known to have chronic kidney disease at the time of admission and 144 patients(4.01%) had serum creatinine levels above 133 micromol/L. However, after the evaluation of renal status by the MDRD equation, 2,250 patients (63.1%)showed a reduction in eGFR of less than 90 mL/min, of whom, 472 (13.1%) even reached the level of moderate renal insufficiency (eGFRchronic total occlusion lesions(CTO) and eight (0.22%) needed shift to coronary artery bypass grafting (CABG) after angiography. Both the presence of CTO lesions and CABG were proved to be associated with decrease of renal function through Fisher's exact test (P= 0.005 8 and 0.041, respectively). The in-hospital mortality rate was 0.47%(17/3 589) which was associated with the degree of renal insufficiency (P=0.001 3). A total of 75 patients(2.09%) of in-hospital bleeding were recorded with 26 patients(0.72%) diagnosed as major bleeding events. 92% (69/75) of the bleeding events occurred after PCI. Bleeding was found to be associated with the degree of renal insufficiency in every type of antithrombotic

    Young women undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) experience greater adverse events than men, potentially due to under-treatment. We sought to compare the 1-year outcomes by sex in patients ≤55 years of age from a contemporary PCI cohort. PROMETHEUS was a retrospective multicenter observational US study comparing outcomes in clopidogrel and prasugrel treated patients following ACS PCI. MACE was defined as a composite of death, myocardial infarction, stroke or unplanned revascularization. Clinically significant bleeding was defined as bleeding requiring transfusion or hospitalization. Hazard ratios were generated using multivariable Cox proportional hazards regression. The study cohort included 4,851 patients of which 1,162 (24.0%) were women and 3,689 (76.0%) were men. In this cohort, the prevalence of diabetes (41.0 vs. 27.9%) and chronic kidney disease (12.7 vs. 7.2%) was higher among women compared with men. Irrespective of sex, prasugrel was used in less than one-third of patients (31.8% in men vs. 28.1% in women, P = 0.01). Unadjusted, 1-year MACE (21.1% vs. 16.2%, P < 0.001) and bleeding (3.6% vs. 2.2%, P = 0.01) was significantly higher in women compared with men, but these results were no longer significant after adjustment for risk (HR 1.13, 95% CI 0.94-1.36 for MACE and HR 1.31, 95% CI 0.85-2.04 for bleeding). Women ≤ 55 years of age undergoing ACS PCI have significantly greater comorbidities than young men. Despite a higher risk clinical phenotype in women, prasugrel use was significantly lower in women than men. Female sex was associated with a significantly higher risk of 1-year MACE and bleeding than male sex, findings that are attributable to baseline differences. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    In patients with non-ST-segment elevation acute coronary syndromes, inhibition of platelet aggregation (IPA) with a potent P2Y 12 inhibitor, ticagrelor, was inferior to tirofiban infusion at 2 hours, indicating that glycoprotein IIb/IIIa inhibitors are still needed. Ticagrelor and eptifibatide bolus only may maximally inhibit platelet aggregation and decrease bleeding, but IPA with ticagrelor and eptifibatide bolus versus 2-hour infusion is unknown. A total of 70 P2Y 12 -naïve patients, with high-risk non-ST-segment elevation acute coronary syndromes, were randomized to ticagrelor and eptifibatide bolus (group 1) versus ticagrelor and eptifibatide bolus with 2-hour infusion (group 2). Levels of IPA with ADP, thrombin receptor-activating peptide, collagen, and high on-treatment platelet reactivity were measured by light transmission aggregometry at baseline and at 2, 6, and 24 hours after percutaneous coronary intervention in both groups. The primary end point, IPA with ADP 20 μmol/L at 2 hours, was 99.59±0.43% in group 1 versus 99.88±1.0% in group 2 ( P zero at 2, 6, and 24 hours in both groups. IPA levels with ADP, thrombin receptor-activating peptide, and collagen were significantly higher at 2 and 6 hours than at 24 hours in both groups. Periprocedural myocardial infarction was not significantly different between the groups. Hemoglobin level was significantly less at 24 hours versus baseline in group 2 (13.35±1.8 versus 12.38±1.8 g/dL, respectively; P hours, which was associated with no significant hemoglobin drop after percutaneous coronary intervention. This obviates the need for eptifibatide 2-hour infusion and might decrease bleeding complications. URL: http://www.clinicaltrials.gov. Unique identifier: NCT01919723. © 2017 The Authors.

    Global Registry of Acute Coronary Events (GRACE) risk score and red blood cell distribution width (RDW) content can both independently predict major adverse cardiac events (MACEs) in patients with acute coronary syndrome (ACS). We investigated the combined predictive value of RDW and GRACE risk score for cardiovascular events in patients with ACS undergoing percutaneous coronary intervention (PCI) for the first time. We enrolled 480 ACS patients. During a median follow-up time of 37.2 months, 70 (14.58%) patients experienced MACEs. Patients were divided into tertiles according to the baseline RDW content (11.30-12.90, 13.00-13.50, 13.60-16.40). GRACE score was positively correlated with RDW content. Multivariate Cox analysis showed that both GRACE score and RDW content were independent predictors of MACEs (hazard ratio 1.039; 95% confidence interval [CI] 1.024-1.055; p risk of MACEs increased with increasing RDW content (p value of combining RDW content and GRACE risk score was significantly improved, also shown by the net reclassification improvement (NRI = 0.352, p value of RDW and GRACE risk score yielded a more accurate predictive value for long-term cardiovascular events in ACS patients who underwent PCI as compared to each measure alone.

    Purpose. Patients may not achieve a clinical benefit after percutaneous cholecystostomy due to the inherent difficulty in identifying patients who truly have infected gallbladders. We attempted to identify imaging and biochemical parameters which would help to predict which patients have infected gallbladders. Methods. A retrospective review was performed of 52 patients undergoing percutaneous cholecystostomy for clinical suspicion of acute cholecystitis in whom bile culture results were available. Multiple imaging and biochemical variables were examined alone and in combination as predictors of infected bile, using logistic regression. Results. Of the 52 patients, 25 (48%) had infected bile. Organisms cultured included Enterococcus, Enterobacter, Klebsiella, Pseudomonas, E. coli, Citrobacter and Candida. No biochemical parameters were significantly predictive of infected bile; white blood cell count >15,000 was weakly associated with greater odds of infected bile (odds ratio 2.0, p = NS). The presence of gallstones, sludge, gallbladder wall thickening and pericholecystic fluid by ultrasound or CT were not predictive of infected bile, alone or in combination, although a trend was observed among patients with CT findings of acute cholecystitis toward a higher 30-day mortality. Radionuclide scans were performed in 31% of patients; all were positive and 66% of these patients had infected bile. Since no patient who underwent a radionuclide scan had a negative study, this variable could not be entered into the regression model due to collinearity. Conclusion. No single CT or ultrasound imaging variable was predictive of infected bile, and only a weak association of white blood cell count with infected bile was seen. No other biochemical parameters had any association with infected bile. The ability of radionuclide scanning to predict infected bile was higher than that of ultrasound or CT. This study illustrates the continued challenge to identify bacterial cholecystitis

    Variability in individual response profiles to antiplatelet therapy, in particular clopidogrel, is a well-established phenomenon. Genetic variations of the cytochrome P450 (CYP) 2C19 enzyme, a key determinant in clopidogrel metabolism, have been associated with clopidogrel response profiles. Moreover, the presence of a CYP2C19 loss-of-function allele is associated with an increased risk of atherothrombotic events among clopidogrel-treated patients undergoing percutaneous coronary interventions (PCI), prompting studies evaluating the use of genetic tests to identify patients who may be potential candidates for alternative platelet P2Y 12 receptor inhibiting therapies (prasugrel or ticagrelor). Areas covered: The present manuscript provides an overview of genetic factors associated with response profiles to platelet P2Y 12 receptor inhibitors and their clinical implications, as well as the most recent developments and future considerations on the role of genetic testing in patients undergoing PCI. Expert commentary: The availability of more user-friendly genetic tests has contributed towards the development of many ongoing clinical trials and personalized medicine programs for patients undergoing PCI. Results of pilot investigations have shown promising results, which however need to be confirmed in larger-scale studies to support the routine use of genetic testing as a strategy to personalize antiplatelet therapy and improve clinical outcomes.

    To evaluate the relationship between aortic inflammation as assessed by {sup 18}F-fluorodeoxyglucose-positron emission tomography ({sup 18}F-FDG-PET) and features of plaque vulnerability as assessed by frequency domain-optical coherence tomography (FD-OCT). We enrolled 30 consecutive non-ST-segment elevation acute coronary syndrome patients undergoing percutaneous coronary intervention. All patients underwent three-vessel OCT before intervention and {sup 18}F-FDG-PET before discharge. Univariable and C-reactive protein (CRP)-adjusted linear regression analyses were performed between features of vulnerability [namely:lipid-rich plaques with and without macrophages and thin cap fibroatheromas (TCFA)] and {sup 18}F-FDG uptake in both ascending (AA) and descending aorta (DA) [measured either as averaged mean and maximum target-to-blood ratio (TBR) or as active slices (TBR{sub max} ≥ 1.6)]. Mean age was 62 years, and 26 patients were male. On univariable linear regression analysis TBR{sub mean} and TBR{sub max} in DA was associated with the number of lipid-rich plaques (β = 4.22; 95%CI 0.05-8.39; p = 0.047 and β = 3.72; 95%CI 1.14-6.30; p = 0.006, respectively). TBR{sub max} in DA was also associated with the number of lipid-rich plaques containing macrophages (β = 2.40; 95%CI 0.07-4.72; p = 0.044). A significant CRP adjusted linear association between the TBR{sub max} in DA and the number of lipid-rich plaques was observed (CRP-adjusted β = 3.58; 95%CI -0.91-6.25; p = 0.01). TBR{sub max} in DA showed a trend towards significant CRP-adjusted association with number of lipid-rich plaques with macrophages (CRP-adjusted β = 2.30; 95%CI -0.11-4.71; p = 0.06). We also observed a CRP-adjusted (β = 2.34; 95%CI 0.22-4.47; p = 0.031) linear association between the number of active slices in DA and the number of lipid-rich plaques.

    Full Text Available Contrast Induced Nephropathy (CIN is a feared complication of numerous radiological procedures that expose patients to contrast media. The most notorious of these procedures is percutaneous coronary intervention (PCI. Not only is this a leading cause of morbidity and mortality, but it also adds to increased costs in high risk patients undergoing PCI. It is thought to result from direct cytotoxicity and hemodynamic challenge to renal tissue. CIN is defined as an increase in serum creatinine by either ≥0.5 mg/dL or by ≥25% from baseline within the first 2-3 days after contrast administration, after other causes of renal impairment have been excluded. The incidence is considerably higher in diabetics, elderly and patients with pre-existing renal disease when compared to the general population. The nephrotoxic potential of various contrast agents must be evaluated completely, with prevention as the mainstay of focus as no effective treatment exists. The purpose of this article is to examine the pathophysiology, risk factors, and clinical course of CIN, as well as the most recent studies dealing with its prevention and potential therapeutic interventions, especially during PCI. The role of gadolinium as an alternative to iodinated contrast is also discussed.

    Ectopic adrenocorticotropic hormone (ACTH)-related Cushing's syndrome can lead to multiple complications including severe immunosuppression. If the ACTH-secreting tumour cannot be found, definitive treatment is surgical adrenalectomy, typically followed by glucocorticoid replacement. Here, we present a case of fulminant respiratory failure secondary to coinfection with Pneumocystis jirovecii and cytomegalovirus in a patient with ectopic ACTH-dependent Cushing's syndrome with occult primary. Due to significant deconditioning, she was unable to undergo definitive adrenalectomy and instead underwent percutaneous microwave ablation of the adrenal glands. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    This study sought to compare clinical outcomes in a contemporary acute coronary syndrome (ACS) percutaneous coronary intervention (PCI) cohort stratified by chronic kidney disease (CKD) status. Patients with CKD exhibit high risks for both thrombotic and bleeding events, thus complicating decision making regarding antiplatelet therapy in the setting of ACS. The PROMETHEUS study was a multicenter observational study comparing outcomes with prasugrel versus clopidogrel in ACS PCI patients. Major adverse cardiac events (MACE) at 90 days and at 1 year were defined as a composite of death, myocardial infarction, stroke, or unplanned revascularization. Clinically significant bleeding was defined as bleeding requiring transfusion or hospitalization. Cox regression multivariable analysis was performed for adjusted associations between CKD status and clinical outcomes. Hazard ratios for prasugrel versus clopidogrel treatment were generated using propensity score stratification. The total cohort included 19,832 patients, 28.3% with and 71.7% without CKD. CKD patients were older with greater comorbidities including diabetes and multivessel disease. Prasugrel was less often prescribed to CKD versus non-CKD patients (11.0% vs. 24.0%, respectively; p < 0.001). At 1 year, CKD was associated with higher adjusted risk of MACE (1.27; 95% confidence interval: 1.18 to 1.37) and bleeding (1.46; 95% confidence interval: 1.24 to 1.73). Although unadjusted rates of 1-year MACE were lower with prasugrel versus clopidogrel in both CKD (18.3% vs. 26.5%; p < 0.001) and non-CKD (10.9% vs. 17.9%; p < 0.001) patients, associations were attenuated after propensity stratification. Similarly, unadjusted differences in 1-year bleeding with prasugrel versus clopidogrel (6.0% vs. 7.4%; p = 0.18 in CKD patients; 2.6% vs. 3.5%; p = 0.008 in non-CKD patients) were not significant after propensity score adjustment. Although risks for 1-year MACE were significantly higher in ACS PCI patients with

    AIM: To present our experience using intravenous sedoanalgesia for percutaneous biliary drainage. MATERIALS AND METHODS: This study comprised 100 patients, all of whom were continuously monitored [electrocardiogram (ECG), blood pressure, pulse oxymetry] and received an initial dose of 2 mg midazolam followed by 0.02 mg fentanyl. Before every anticipated painful procedure, a maintenance dose of 0.01 mg fentanyl was administered. If the procedure continued and the patient became aware, another 1 mg midazolam was given. This was repeated if patients felt pain. A total dose of 0.08 mg fentanyl and 7 mg midazolam was never exceeded. Immediately after the procedure, the nurse was asked to evaluate patients' pain score. The patients were asked 3 h later to complete a visual 10-degree pain score scale. RESULTS: The average dose of fentanyl and midazolam was 0.042 mg (0.03-0.08 mg) and 4.28 mg (2-7 mg), respectively. Only one patient recorded the procedure as painful. The scores given by the attending nurse (1-7 points, mean 2.9) correlated well with those given by the patients (1-6 points, mean 2.72). No complications were noted. CONCLUSION: According to our experience, interventional radiologists practising biliary procedures can administer low doses of midazolam and minimize the doses of fentanyl, without loss of adequate sedation and analgesia.

    While transradial approach to conduct percutaneous coronary interventions offers multiple advantages, the procedure can cause radial artery damage and occlusion. Because radial artery is the preferred site for the creation of an arteriovenous fistula to provide dialysis, patients with chronic kidney disease are particularly dependent on radial artery for their long-term survival. In this retrospective study, we investigated the prevalence of chronic kidney disease in patients undergoing coronary interventions via radial artery. Stage of chronic kidney disease was based on estimated glomerular filtration rate and National Kidney Foundation - Kidney Disease Outcomes Quality Initiative guidelines. A total of 497 patients undergoing transradial percutaneous coronary interventions were included. Over 70.4% (350/497) of the patients had chronic kidney disease. Stage II chronic kidney disease was observed in 243 (69%) patients (estimated glomerular filtration rate = 76.0 ± 8.4 mL/min). Stage III was observed in 93 (27%) patients (estimated glomerular filtration rate = 49 ± 7.5 mL/min). Stage IV chronic kidney disease was observed in 5 (1%) patients (estimated glomerular filtration rate = 25.6 ± 4.3 mL/min) and Stage V chronic kidney disease was observed in 9 (3%) patients (estimated glomerular filtration rate = 9.3 ± 3.5 mL/min). Overall, 107 of 350 patients (30%) had advanced chronic kidney disease, that is, stage III-V chronic kidney disease. Importantly, 14 of the 107 (13%) patients had either stage IV or V chronic kidney disease. This study finds that nearly one-third of the patients undergoing transradial percutaneous coronary interventions have advanced chronic kidney disease. Because many of these patients may require dialysis, the use of radial artery to conduct percutaneous coronary interventions must be carefully considered in chronic kidney disease population.

    Due to the complex anatomical and haemodynamic consequences of hypoplastic left heart syndrome (HLHS), patients with the condition require multistage surgical and supportive interventional treatment. Percutaneous interventions may be required between each stage of surgical palliation, sometimes simultaneously with surgery as hybrid interventions, or after completion of multistage treatment. Recent advances in the field of interventional cardiology, including new devices and techniques, have significantly contributed to improving results of multistage HLHS palliation. Knowledge of the potential interventional options as well as the limitation of percutaneous interventions will enable the creation of safe and effective treatment protocols in this highly challenging group of patients. In this comprehensive review we discuss the types, goals, and potential complications of transcatheter interventions in patients with HLHS.

    Low body mass index (BMI) and serum creatinine are surrogate markers of frailty and sarcopenia. Their relationship with cause-specific mortality in elderly patients undergoing percutaneous coronary intervention is not well studied. We determined long-term cardiovascular and noncardiovascular mortality in 9394 consecutive patients aged ≥65 years who underwent percutaneous coronary intervention from 2000 to 2011. BMI and serum creatinine were divided into 4 categories. During a median follow-up of 4.2 years (interquartile range 1.8-7.3 years), 3243 patients (33.4%) died. In the multivariable model, compared with patients with normal BMI, patients with low BMI had significantly increased all-cause mortality (hazard ratio [HR] 1.4, 95% CI 1.1-1.7), which was related to both cardiovascular causes (HR 1.4, 95% CI 1.0-1.8) and noncardiovascular causes (HR 1.4, 95% CI 1.06-1.9). Compared with normal BMI, significant reduction was noted in patients who were overweight and obese in terms of cardiovascular mortality (overweight: HR 0.77, 95% CI 0.67-0.88; obese: HR 0.80, 95% CI 0.70-0.93) and noncardiovascular mortality (overweight: HR 0.85, 95% CI 0.74-0.97; obese: HR 0.82, 95% CI 0.72-0.95). In a multivariable model, in patients with normal BMI, low creatinine (≤0.70 mg/dL) was significantly associated with increased all-cause mortality (HR 1.8, 95% CI 1.3-2.5) and cardiovascular mortality (HR 2.3, 95% CI 1.4-3.8) compared with patients with normal creatinine (0.71-1.0 mg/dL); however, this was not observed in other BMI categories. We identified a new subgroup of patients with low serum creatinine and normal BMI that was associated with increased all-cause mortality and cardiovascular mortality in elderly patients undergoing percutaneous coronary intervention. Low BMI was associated with increased cardiovascular and noncardiovascular mortality. Nutritional support, resistance training, and weight-gain strategies may have potential roles for these patients undergoing

    To assess whether chronic renal insufficiency and anemia are significant independent and combined predictors of poor long-term outcomes after percutaneous coronary intervention (PCI). We examined the clinical and outcome data of 3770 PCI patients based on the pre-PCI values of glomerular filtration rate (GFR) and hemoglobin (Hb). Depending on their baseline GFR and Hb, the patients were classified into six groups: normal renal function with anemia or not; mild renal impairment with combined anemia or not; severe renal insufficiency with anemia or not. The clinical features and prognosis of patients were compared. Significant differences were found between the groups regarding female gender, age, body mass index, prior history of hypertension, diabetes mellitus, prior stroke, acute coronary syndrome, systolic blood pressure, left ventricular ejection fraction, total serum cholesterol, LDL-C and angiographic features (P renal insufficiency with anemia (HR 4.123, 95% CI 1.637-10.386, P = 0.003), severe renal insufficiency without anemia (HR 5.287, 95% CI 1.627-17.183, P = 0. 006) and severe renal insufficiency with anemia (HR 7.134, 95% CI 2.180-23.342, P = 0.001) having a statistically significant decrease in survival in patients undergoing PCI . Renal insufficiency and anemia are significant independent and combined predictors of long-term mortality in patients undergoing PCI.

    Current guidelines have recommended against coronary revascularization before noncardiac surgery in patients with asymptomatic coronary artery disease. However, myocardial infarction after thoracic aneurysm (TA) repair dramatically increases the morbidity and mortality. Revascularization with coronary artery bypass grafting before TA repair minimizes the incidence of perioperative ischemia. However, the recovery can be prolonged, and a percentage of patients will either never return for aneurysm repair or will develop a rupture during convalescence. Percutaneous coronary intervention (PCI) before TA repair might be preferable. Previous studies examining PCI before major vascular surgery included few patients with TAs. We examined the outcomes of patients undergoing PCI before TA repair. From 1997 to 2012, 592 patients underwent TA repair. Patients presenting for elective repair underwent cardiac catheterization before surgery. Those with significant single- or double-vessel coronary artery disease underwent PCI. The perioperative outcomes were examined and compared with those of patients undergoing TA repair without revascularization. A total of 44 patients (7.4%) underwent PCI with bare metal stents before surgery. No PCI-related complications occurred. Dual antiplatelet therapy was administered for 4 to 6 weeks. No instances of aneurysm rupture occurred in the interval between PCI and surgery. The incidence of stent thrombosis, myocardial infarction, and mortality for those undergoing PCI was 0. No bleeding complications occurred. PCI is safe and efficacious in patients undergoing TA repair. Aneurysm rupture did not occur in the interval before surgery. Antiplatelet therapy did not increase the risk of bleeding complications. Stent thrombosis was not seen. We recommend PCI those with significant single- or double-vessel coronary artery disease before elective TA repair. Copyright © 2014 The American Association for Thoracic Surgery.

    Transradial access (TRA) improves outcome compared with trans-femoral access for the management of patients with acute coronary syndromes. In this setting, it is unknown whether the activation of a pre-hospital alarm system (PHAS) confers additional benefit for the prognosis of patients with ST-segment elevation myocardial infarction (STEMI). We retrospectively analyzed a cohort of patients with a first STEMI who underwent a primary percutaneous coronary intervention (PPCI) at a single center within a prospective cohort of acute coronary syndrome patients (SPUM-ACS). TRA was used in 85% of patients. We assessed how PHAS (n=165) vs. no-PHAS (n=166) activation was associated with the composite outcome of all-cause mortality and recurrence of myocardial infarction (MI) at 1-year follow-up. As secondary outcomes, the individual clinical endpoints were separately assessed for association. Compared with no-PHAS patients, patients in the PHAS group were predominantly women, and presented more frequently with dyslipidemia and cardiac arrest. A significant reduction in the composite outcome of all-cause mortality and recurrent MI at 1-year was observed in the PHAS group, compared with no-PHAS (3.6% vs. 8.5%, p=0.027). When adjusted for age, sex and resuscitation status, PHAS activation remained associated with decreased all-cause mortality and recurrent MI (HR: 0.36 [95% CI: 0.13-0.95]; p=0.040). This study suggests that the benefit of PHAS activation in STEMI patients undergoing PPCI persists also in the era of TRA. Copyright © 2016 European Federation of Internal Medicine.

    Previous studies of contrast-induced acute kidney injury (CI-AKI) were mostly based on selective percutaneous coronary intervention (PCI) cases, and risk factors of CI-AKI after emergency PCI are unclear. The aim of this study was to explore the risk factors of CI-AKI in a Chinese population undergoing emergency PCI. A total of 1061 consecutive patients undergoing emergency PCI during January 2013 and June 2015 were enrolled and divided into CI-AKI and non-CI-AKI group. Univariable and multivariable analyses were used to identify the risk factors of CI-AKI in emergency PCI patients. CI-AKI was defined as an increase in serum creatinine ≥25% or ≥0.5 mg/dl (44.2 μmol/L) above baseline within 3 days after exposure to contrast medium. The incidence of CI-AKI in patients undergoing emergency PCI was 22.7% (241/1061). Logistic multivariable analysis showed that body surface area (BSA) (odds ratio [OR] 0.213, 95% confidence interval [CI]: 0.075-0.607, P= 0.004), history of myocardial infarction (MI) (OR 1.642, 95% CI: 1.079-2.499, P= 0.021), left ventricular ejection fraction (LVEF) (OR 0.969, 95% CI: 0.944-0.994, P= 0.015), hemoglobin (Hb) (OR 0.988, 95% CI: 0.976-1.000, P= 0.045), estimated glomerular filtration rate (OR 1.027, 95% CI: 1.018-1.037, P < 0.001), left anterior descending (LAD) stented (OR 1.464, 95% CI: 1.000-2.145, P= 0.050), aspirin (OR 0.097, 95%CI: 0.009-0.987, P= 0.049), and diuretics use (OR 1.850, 95% CI: 1.233-2.777, P= 0.003) were independent predictors of CI-AKI in patients undergoing emergency PCI. History of MI, low BSA, LVEF and Hb level, LAD stented, and diuretics use are associated with increased risk of CI-AKI in patients undergoing emergency PCI.

    This study aimed to describe the incidence and periprocedural predictors of permanent work disability (PWD) pension among patients ≤50 years old who underwent percutaneous coronary intervention (PCI). Patient records of 910 consecutive patients undergoing PCI at four Finnish hospitals in 2002-2012 were reviewed for baseline and procedural data and late adverse events. Data on permanent work disability (PWD) pension allocation were acquired from the Finnish Centre for Pensions, which governs the statutory pension security in Finland. Mean follow-up was 41 [standard deviation (SD) 31] months. Altogether 103/910 (11.3%) of patients were on PWD by the end of follow-up, 60 (58.3%) for cardiac diagnoses (cumulative freedom from PWD 81% at 7 years). Independent predictors of PWD were post procedural stroke [hazard ratio (HR) 4.7, 95% confidence interval (95% CI) 1.8-11.9], post procedural myocardial infarction (MI) (HR 3.3, 95% CI 1.8-6.0), diabetes (HR 2.0, 95% CI 1.1-3.7), discharge diuretics (HR 3.5, 95% CI 2.1-5.9), and increasing age (HR 1.2, 95% CI 1.1-1.3). Predictors of PWD for cardiac diagnoses were post procedural stroke and MI, discharge diuretics, and use of calcium-channel blockers, diabetes and older age. Patients ≤50 years old undergoing PCI are at a high risk for subsequent permanent disability for cardiac diagnoses. This finding underscores the need for reinforcing adherence to secondary prevention by cardiac rehabilitation and early collaboration with occupational health care professionals.

    The aim of this study was to determine and localize culprit lesion by myocardial perfusion imaging (MPI) in cases of angiographically detected coronary narrowing >or= 75% of at least one coronary artery. One hundred and thirty-two (132) patients with angiographically detected significant coronary narrowing (>or= 75% luminal stenosis of at least one major coronary artery) were studied. All the patients submitted MPI (99m)Tc-MIBI, with pharmacologic dipyridamole stress protocol with concomitant low level bicycle exercise 50W (DipyEX). We measured relative uptake (99m)Tc-MIBI for each myocardial segment using short-axis myocardial tomogram study. A 5-point scoring system was used to assess the difference between uptake degree in stress and rest studies for the same segments, and we created two indices: Sum reversibility score (SRS), Index of sum reversibility score (ISRS). A total of 396 vascular territories (2244 segments) were analyzed before elective percutaneous coronary intervention (ePCI). Overall sensitivity, specificity and accuracy using SRS were 90.2%, 87.5%, and 89.4%, with a positive predictive value of 94.1%. Overall sensitivity, specificity, and accuracy using ISRS were 94.4%, 90.6%, 93.2% and the positive predictive value was 95.7%. DipyEX MPI with the two indices created, SRS and ISRS, significantly improves sensitivity, specificity and accuracy in the determination and localization of culprit lesions in patients undergoing elective PCI.

    Costs of percutaneous coronary interventions (PCI) have an important impact on health care expenditures. Despite the present stress upon the cost-effectiveness issues in medicine, few comprehensive data exist on costs and resource use in different clinical settings. To assess catheterisation laboratory costs related to use of drugs and single-use devices in patients undergoing PCI due to coronary artery disease. Retrospective analysis of 1500 consecutive PCIs (radial approach, n = 1103; femoral approach, n = 397) performed due to ST segment elevation myocardial infarction (STEMI; n = 345) and non ST-segment elevation myocardial infarction (NSTEMI; n = 426) as well as unstable angina (UA; n = 489) and stable angina (SA; n = 241) was undertaken. Comparative cost analysis was performed and shown in local currency units (PLN). The cath lab costs were higher in STEMI (4295.01 ± 2384.54PLN, p costs were positively correlated with X-ray dose, fluoroscopy, and total procedure times. Patients' age negatively correlated with cath lab costs in STEMI/NSTEMI patients. Cath lab costs were higher in STEMI patients compared to other groups. In STEMI/NSTEMI they were lower in older patients. In all analysed groups costs were related to the level of procedural difficulty. In female patients, the costs of PCI performed via radial approach were higher compared to femoral approach. Despite younger age, male patients underwent more expensive procedures.

    Aspirin remains the mainstay of anti-platelet therapy in cardiac patients. However, if a patient is allergic to aspirin and dual anti-platelet therapy is indicated - such as with percutaneous coronary intervention (PCI), then there is no clear guidance. One possibility is aspirin desensitization. A variety of protocols exist for the rapid desensitization of patients with aspirin allergy. The aim of this survey was to assess current knowledge and practice regarding aspirin desensitization in the UK. We conducted a UK wide survey of all UK 116 PCI centers and obtained complete responses from 40 (35.4%) centers. Of these, just 7 (17.5%) centers had previously desensitised patients; 29 (87.9%) centers suggested a lack of a local protocol prevented them from desensitizing, with 10 (30.3%) unsure of how to conduct desensitization. Only 5 (12.5%) centers had a local policy for aspirin desensitization although 25 (64.1%) units had a clinical strategy for dealing with aspirin allergy; the majority (72%) giving higher doses of thienopyridine class drugs. In the UK, there appears to be no consistent approach to patients with aspirin allergy. Patients undergoing PCI benefit from dual anti-platelet therapy (including aspirin), and aspirin desensitization in those with known allergy may facilitate this. Sustained effort should be placed on encouraging UK centers to use desensitization as a treatment modality prior to PCI rather than avoiding aspirin altogether.

Nineteen patients with unilateral clubfeet were retrospectively reviewed from our database from July 2012 to June 2016. The result in all the cases was rated as excellent according to the scale of International Clubfoot Study Group (ICSG. The affected sides were taken as Group CF and the contralateral sides as Group CL. Three-dimensional gait analysis was applied for the functional evaluation of the involved foot. Results. Statistical difference was found in physical parameters of passive ankle dorsiflexion and plantar-flexion. No statistical difference was found in temporal-spatial parameters. There was statistical difference in kinematic parameters of total ankle rotation, ankle range of motion, and internal foot progression angle and in kinetic parameters of peak ankle power. No statistical difference was found in other kinematic and kinetic parameters. Conclusions. It is demonstrated that the procedure of PAT is safe and efficient for correcting the equinus deformity in case of clubfoot management and preserving the main function of Achilles tendon at the minimum of four-year follow-up.

    Buried bumper syndrome (BBS) is a rare complication developed after percutaneous endoscopic gastrostomy (PEG). We report a case of a 38-year-old male patient who sustained severe traumatic brain injury that was complicated with early BBS after PEG tube insertion. On admission, bedside PEG was performed, and 7 days later the patient developed signs of sepsis with rapid progression to septic shock and acute kidney injury. Abdominal CT scan revealed no collection or leakage of the contrast, but showed malpositioning of the tube bumper at the edge of the stomach and not inside of it. Diagnostic endoscopy revealed that the bumper was hidden in the posterolateral part of the stomach wall forming a tract inside of it, which confirmed the diagnosis of BBS. The patient underwent laparotomy with a repair of the stomach wall perforation, and the early postoperative course was uneventful. Acute BBS is a rare complication of PEG tube insertion which could be manifested with severe complications such as pressure necrosis, peritonitis and septic shock. Early identification is the mainstay to prevent such complications. Treatment selection is primarily guided by the presenting complications, ranging from simple endoscopic replacement to surgical laparotomy. PMID:27462190

    In this study, we aimed to investigate the impact of prophylactic intracoronary adenosine administered during percutaneous coronary intervention (PCI) due to unstable angina pectoris on myonecrosis by measuring post-procedural levels of cardiac troponin I (cTnI) and creatine kinase-myocardial band (CK-MB). A total of 122 patients with unstable angina undergoing PCI were included in this single-center, double-blind, randomized study. The patients were randomly allocated to adenosine and placebo groups. In the adenosine group, a single-dose of intracoronary adenosine (100 μg for the right coronary artery and 150 μg for the left coronary artery) was administered. Primary endpoint was post-PCI myonecrosis, which was defined as abnormal levels of periprocedural cTnI. Secondary endpoints were defined as elevated cTnI levels [5 × upper limit of normal (ULN)], abnormal CK-MB levels, angiographic coronary flow measured by Thrombolysis In Myocardial Infarction (TIMI) frame count (TFC), the cumulative incidence of in-hospital death and in-hospital urgent target vessel revascularization (TVR). Clinical and angiographic characteristics of both adenosine (61 patients, 61 ± 9 years) and placebo (61 patients, 59 ± 10 years) groups were similar (p > 0.05 for all). Post-procedural abnormal cTnI levels in the adenosine group were significantly lower than the placebo group (32 % vs. 55 %, p: 0.011). cTnI >5 × ULN (21 % vs. 31 %, p: 0.217) and abnormal CK-MB levels (11 % vs. 19 %, p: 0.263) were similar in both groups. Post-procedural TFCs in the adenosine group were significantly lower than the placebo group (24 ± 4 vs. 27 ± 5, p: 0.004). In-hospital events including death and urgent TVR were not observed in either group. Intracoronary administration of single-dose adenosine in patients with unstable angina undergoing PCI is associated with decreased periprocedural myonecrosis and improved coronary blood flow.

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

    Full Text Available Background: Contrast induced kidney injury is an acute renal dysfunction that is secondary to the administration of radio contrast media. The purpose of this study was to evaluate the levels of urotensin-II (UT-II and endothelin-I (ET-I after contrast media administration in patients undergoing percutaneous coronary interventions. Materials and Methods: In this prospective cohort study, we evaluated 78 patients with coronary artery disease who were scheduled for and ultimately underwent percutaneous coronary interventions. As a contrast material, nonionic contrast media was used in various amounts (70-480 mL. Blood and urine samples were obtained to measure U-II, ET-I just before and at the twenty-fourth hour of percutaneous coronary interventions. Results: Compared to baseline, twenty-fourth hour creatinine levels were significantly increased ( P < 0.001. The twenty-fourth hour serum and urine levels of both UT-II and ET-I were also significantly increased compared to baseline ( P < 0.001 for all and 24 th hour serum and urine UT-II (r = 0.322, P = 0.004; r = 0.302, P = 0.007 respectively, ET-I (r = 0.511, P < 0.001; r = 0.266, P = 0.019 respectively levels were significantly correlated with the amount of contrast media. Conclusion: Our study indicates that; increased UT-II and ET-I levels seem to be a consequence of hazardous effects of contrast media on blood vessels and the kidney.

    The study objective was to assess the effect of music on the physiologic and psychologic parameters in patients undergoing application of a C-clamp after percutaneous coronary interventions (PCI). A repeated-measures randomized controlled trial was used. The study took place in three intensive care units in Hong Kong. Sixty-six patients undergoing application of a C-clamp after PCI were recruited. Physiologic parameters were blood pressure, heart rate, respiratory rate, and oxygen saturation. Psychologic parameters were measured using the University of California at Los Angeles universal pain score. Patients were randomized to receive 45 minutes of music therapy or 45 minutes of an uninterrupted rest period. Three types of music were used, including Chinese classical music, religious music, and Western classical music that had slow beats and was relaxing. The data were collected from September 2004 to December 2005. In the experimental group there were statistically significant reductions in heart rate (P Music is a simple, safe, and effective method of reducing potentially harmful physiologic and psychologic responses arising from pain in patients post-PCI undergoing a C-clamp procedure.

    Hughes-Stovin syndrome is an extremely rare entity. We present a case of a 42-year-old man, who developed deep vein and inferior vena cava (IVC) thrombosis, repeated internal bleeding and pulmonary artery aneurysms (PAAs). The patient presented with massive hemoptysis and with PAAs of a 2.5 cm maximum diameter. We describe the successful percutaneous transhepatic venous embolization of the PAAs due to occluded common vascular pathways to the pulmonary artery.

    Post-cardiac injury syndrome (PCIS) is a syndrome characterized by pericardial and/or pleural effusion, triggered by a cardiac injury, usually a myocardial infarction or cardiac surgery, rarely a minor cardiovascular percutaneous procedure. Nowadays, the post-cardiac injury syndrome, is regaining importance and interest as an emerging cause of pericarditis, especially in developed countries, due to a great and continuous increase in the number and complexity of percutaneous cardiologic procedures. The etiopathogenesis seems mediated by the immunitary system producing immune complexes, which deposit in the pericardium and pleura and trigger an inflammatory response. We present the atypical case of a 76-year-old man presenting with a hydro-pneumothorax, low-grade fever and elevated inflammation markers, after two complex percutaneous coronary interventions, executed 30 and 75 days prior. The clinical features of our case are consistent with the diagnostic criteria of PCIS: prior injury of the pericardium and/or myocardium, fever, leucocytosis, elevated inflammatory markers, remarkable steroid responsiveness and latency period. Only one element does not fit with this diagnosis and does not find any further explanation: the air accompanying the pleural effusion, determining a hydro-pneumothorax and requiring a pleural drainage catheter positioning.

    Controlling cardiovascular risk factors (CVRF) is important for the outcome of interventional practices (percutaneous coronary intervention [PCI]) in ischemic heart disease. The aim is to determine the evolution of the CVRF 6 months after the intervention and their relationship with new events. A descriptive study was conducted on a case series. The variables recorded were: age, sex and chronic kidney disease (CKD), as well as total (TC) and HDL cholesterol, systolic (SBP) and diastolic blood pressure (DBP), smoking habit, and body mass index (BMI), before PCI and after 6 months. The occurrence of death or new PCI during the follow-up was considered an independent variable in a logistic regression analysis. A Pcontrol of CVRF was found. One fifth of the patients had an event in that period, showing association with age and CKD. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

    Numerous studies have reported the relationship between elevated homocysteine (Hcy) levels and the risk of coronary artery disease. However, there is insufficient information about the effects of Hcy levels on long-term clinical outcomes in patients with coronary artery disease undergoing percutaneous coronary intervention (PCI). In the Juntendo-registry cohort from 2003 to 2004, pre-procedural Hcy levels and Hcy thiolactonase activity (HTlase) were measured in 315 consecutive all-comer patients who underwent PCI for stable coronary artery disease or acute coronary syndrome (ACS). Receiver-operating characteristic (ROC) curves were created to assess the optimal cut-off values of Hcy and HTlase. Multivariable Cox proportional hazard regression analysis was used to identify the predictors of clinical outcome. The primary endpoint was all-cause mortality. The patients' mean age was 66±9 years, and 82.5% were males. The median follow-up period was 10.5 years, and overall mortality was 24.5% (73 deaths). On ROC analysis, the optimal cut-off values of Hcy and HTlase were 13.5μmol/L and 230IU/L, respectively. Kaplan-Meier survival analysis showed associations of both higher Hcy levels and lower HTlase activity with worse prognosis (both log-rank p<0.001). On multivariate Cox proportional hazard regression analysis, higher Hcy was strongly associated with the primary outcome, and the adjusted hazard ratio was 3.3 (95% confidence interval, 1.8-5.6; p<0.001). Pre-procedural high Hcy levels and low HTlase activity were associated with worse long-term mortality in Japanese patients undergoing PCI. Moreover, Hcy levels are strongly predictive for mortality, independent of traditional risk factors. This may have implications for risk stratification and the therapeutic approach in this PCI era.

    The subclavian steal syndrome is a rare vascular disease that can be managed by interventional radiology. It is presented the experience with three cases of this syndrome that underwent percutaneous transluminal angioplasty, and a brief literature review is done. Two patients remained asymptomatic 23 and 30 months, respectively, after the procedure. One patient presented with recurrent symptoms 12 months after the dilatation. Considering the low morbidity and good clinical and technical results, percutaneous transluminal angioplasty is the first choice in the subclavian steal syndrome treatment.

    We explored 12-month clinical outcomes of 929 patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) with bare-metal stents (BMS) vs. drug-eluting stents (DES) from the prospective multicenter AFCAS (Atrial Fibrillation undergoing Coronary Artery Stenting) registry. METHODS AND RESULTS: Endpoints included the first occurrence of major adverse cardiac and cerebrovascular events (MACCE), defined as a composite of all-cause death, myocardial infarction (MI), target vessel revascularization, definite/probable stent thrombosis (ST), transient ischemic attack or stroke. Bleeding events were defined according to the Bleeding Academic Research Consortium criteria. Altogether, 673 (72.4%) patients received BMS and 220 (23.7%) at least one DES. Patients treated with DES more often had diabetes and prior ischemic events, and a longer stent length (Pheart failure and were more likely to present with acute ST-elevation MI (P<0.05 for both). At 12-month follow-up, rates and risks of MACCE and total bleeding events were comparable between the groups (22.0% with BMS vs. 19.5% with DES, P=0.51, hazard ratio (HR) 0.89, 95% confidence interval (CI) 0.63-1.25 for DES) and (19.5% vs. 15.0%, respectively, P=0.16, HR 0.75, 95% CI 0.51-1.09 for DES). Definite/probable ST was more frequent in the BMS group (1.9% vs. 0%, respectively, P=0.046). In real-world patients with AF undergoing PCI, DES use was associated with outcomes comparable to those with BMS without excess bleeding complications. More ST was seen in BMS-treated patients.

    Objectives: This study sought to identify clinical and procedural predictors of elevated radiation dose received by patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) and to determine if elevated radiation dose was predictive of mortality in this population. Background: Little data exist regarding the impact of excessive radiation burden on clinical outcomes in patients undergoing PCI. Methods: The study population included 1,039 patients who underwent PCI for an AMI between January 1, 2007 and December 31, 2008 at an academic tertiary care teaching hospital. Cumulative skin dose (measured in milligray [mGy]) was selected as a measurement of patient radiation burden. Clinical and procedural variables were analyzed in multiple logistic and linear regression models to determine predictors of higher skin dose, and its impact was evaluated on all-cause intermediate-term mortality at two years. Results: Median skin dose was 2120 mGy (IQR 1379–3190 mGy) in the overall population, of which 153 (20.8%) patients received an elevated skin dose (defined as a skin dose > 4,000 mGy). Independent predictors of elevated skin dose included male gender, obesity, multivessel intervention, and presentation with a non-ST-elevation MI (NSTEMI) versus an ST-elevation MI (STEMI). Increased skin dose was not predictive of intermediate-term mortality by multivariate analysis in the overall population or in either subgroup of STEMI and NSTEMI. Conclusions: In this contemporary observational study examining patients with AMI undergoing PCI, male gender, obesity, multivessel intervention, and presentation with a NSTEMI were associated with increased radiation exposure.

    Patients with head and neck carcinoma are often provided concurrent chemoradiotherapy (CCRT), but they experience severe mucositis and dysphagia. These side effects can lead to decreased oral intake, resulting in interruption of treatment. In our hospital, from September 2007, all patients with oropharyngeal cancer who were to receive CCRT, were principally offered percutaneous endoscopic gastrostomy (PEG) before the start of treatment, and tube feeding was started when swallowing became impaired, to accomplish the treatment as planned. To evaluate the effect of prophylactic PEG, outcome measures in this study included the frequency of unplanned break from CCRT, nutritional deterioration and required analgesic during CCRT, complication of PEG, and patient satisfaction between 15 patients with PEG and 11 patients without PEG as a control group. Although no significant weight loss occurred in either group, there were fewer patients with a Body Mass Index <18.5 in the PEG group after CCRT than in the control group. Regarding the treatment, most patients were satisfied with their PEG and considered that prophylactic PEG was necessary and helpful in completing the CCRT. This study suggests that prophylactic PEG helps patients to complete CCRT both mentally and nutritionally. (author)

Percutaneous tibial nerve stimulation (PTNS is derived from acupuncture used in Chinese traditional medicine and was first described in the early 1980s. It is a neuromodulation technique used to modulate bladder function and facilitate storage. Being a minimally invasive, easily applicable, but time-consuming treatment, future developments with implantable devices might be the solution for the logistical problems and economic burden associated with PTNS on the long term. This nonsystematic review provides a current overview on PTNS and its effectiveness in the treatment of OAB for both adults and children.

Shortly after stone disintegration, he suffered acute hypoxic and hypotension, and showed cyanoderma of face and chest skin, ocular proptosis, jugular filling and ventricular fibrillation. Dopamine and adrenaline was intravenously injected. The patient was turned over to supine position and external cardiac massage and electric defibrillation were carried out immediately. The patient finally cardioverted. His vital signs subsequently became stable and cyanoderma faded. The patient was eventually discharged from the intensive care unit three days following the event. Conclusion: Severe complications such as cardiac arrest could happen during PCNL. Close monitoring the vital signs is essential for early finding and quick response to rescue.

    Previous studies have shown that aortic valve calcification (AVC) was associated with cardiovascular events and mortality. On the other hand, periprocedural myocardial injury (PMI) in percutaneous coronary intervention (PCI) is a well-known predictor of subsequent mortality and poor clinical outcomes. The purpose of the study was to assess the hypothesis that the presence of AVC could predict PMI in PCI. This study included 370 patients treated with PCI for stable angina pectoris. AVC was defined as bright echoes >1 mm on one or more cusps of the aortic valve on ultrasound cardiography (UCG). PMI was defined as an increase in high-sensitivity troponin T level of >5 times the upper normal limit (>0.070 ng/ml) at 24 hours after PCI. AVC was detected in 45.9% of the patients (n=170). The incidence of PMI was significantly higher in the patients with AVC than in those without AVC (43.5% vs 21.0%, p<0.001). The presence of AVC independently predicted PMI after adjusting for other significant variables (odds ratio 2.26, 95% confidence interval 1.37-3.74, p=0.002). Other predictors were male sex, age, estimated glomerular filtration rate, and total stent length. Furthermore to predict PMI, adding AVC to the established risk factors significantly improved the area under the receiver operating characteristic curves, from 0.68 to 0.72, of the PMI prediction model (p=0.025). The presence of AVC detected in UCG could predict the incidence of PMI.

    Full Text Available Abstract Background Administration of abciximab during primary percutaneous coronary intervention is an effective adjunctive therapy in the treatment of patients with ST-segment elevation myocardial infarction. Recent small-scaled studies have suggested that intracoronary administration of abciximab during primary percutaneous coronary intervention is superior to conventional intravenous administration. This study has been designed to investigate whether intracoronary bolus administration of abciximab is more effective than intravenous bolus administration in improving myocardial perfusion in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention with thrombus aspiration. Methods/Design The Comparison of IntraCoronary versus intravenous abciximab administration during Emergency Reperfusion Of ST-segment elevation myocardial infarction (CICERO trial is a single-center, prospective, randomized open-label trial with blinded evaluation of endpoints. A total of 530 patients with STEMI undergoing primary percutaneous coronary intervention are randomly assigned to either an intracoronary or intravenous bolus of weight-adjusted abciximab. The primary end point is the incidence of >70% ST-segment elevation resolution. Secondary end points consist of post-procedural residual ST-segment deviation, myocardial blush grade, distal embolization, enzymatic infarct size, in-hospital bleeding, and clinical outcome at 30 days and 1 year. Discussion The CICERO trial is the first clinical trial to date to verify the effect of intracoronary versus intravenous administration of abciximab on myocardial perfusion in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention with thrombus aspiration.

    Contrast-induced nephropathy (CIN) is an important complication in the use of iodinated contrast media. The present study aimed to assess the safety and efficacy of prostaglandin E1 (PGE1) in prevention of CIN in patients with high-risk factors undergoing percutaneous coronary intervention (PCI). The study group consisted of 163 patients who had undergone a coronary intervention procedure between January 1, 2012 and October 31, 2012. Study participants were randomly assigned to either the PGE1 group (82 patients) or the control group (81 patients). Patients in the PGE1 group received PGE1 intravenous infusion of 20 ng/kg/min for 6 h before and after the administration of contrast media. The control group received 0.9 % sodium chloride solution for routine hydration only. A nonionic, low-osmolality contrast agent was used in our laboratory at this time. Serum creatinine (Scr) values and estimated glomerular filtration rate were measured before and within 48 h of the administration of contrast agents. CIN was defined as an increase of ≥0.5 mg/dL or ≥ a 25 % increase in Scr concentrations over baseline within 48 h of angiography. The amount of contrast agent administered was similar for the PGE1 and control groups (156 ± 63 vs. 161 ± 68 mL, P > 0.05). The incidence of CIN was lower in the PGE1 group than in the control group (3.7 vs. 11.1 %, P < 0.05). No serious adverse effects were observed. In patients with high-risk factors undergoing PCI, the use of PGE1 for prevention of CIN is safe and efficacious.

    It is not yet clear whether a difference in in-hospital morality between patients with and without renal insufficiency undergoing percutaneous coronary intervention (PCI) exists. Therefore, the aim of the present study was to investigate if such as association exists in Japan. Data from the Tokai Acute Myocardial Infarction Study II were used. This was a prospective study of all 3274 patients admitted with acute myocardial infarction (AMI) to the 15 participating hospitals from 2001 to 2003. We abstracted the baseline and procedural characteristics as well as in-hospital mortality from detailed chart reviews. Patients were stratified into 2 groups according to the estimated creatinine clearance on admission. The creatinine clearance values were available in 2116, 107 of whom had renal insufficiency. The patients with renal insufficiency were more likely to be older, female, not independent in their daily activities, have lower body mass index and higher heart rate values on admission, lower prevalences of hypercholesterolemia and peptic ulcers, greater prevalences of diabetes, angina, previous heart failure, previous renal failure, previous cerebrovascular disease, aortic aneurysm, worse clinical course such as bleeding, and a multivessel coronary disease. Vasopressors, an intra-aortic balloon pump, and mechanical ventilation were frequently used in the patients with renal insufficiency, while thrombolytics were used less frequently. The patients with renal insufficiency had a higher in-hospital mortality rate than those without. Multivariate analysis identified renal insufficiency as an independent predictor of in-hospital death. The results suggest that renal insufficiency is an independent predictor of in-hospital death among AMI patients undergoing PCI.

    We aimed to determine the association between the change in mean platelet volume (MPV) over time and aspirin/ clopidogrel resistance in patients undergoing percutaneous coronary intervention (PCI). The MPV and platelet function were analysed in 302 patients who underwent PCI. MPV changes were associated with increased aspirin reaction units (ARU, r = 0.114; P = 0.047), increased P2Y12 reaction units (PRU, r = 0.193; P = 0.001), and decreased P2Y12% inhibition (PI%, r = - 0.273; P resistant group (≥235 PRU or ≤15% of PI%) showed a significantly higher positive change in MPV (ΔMPV) values than the clopidogrel responder group (0.53 ± 0.78 vs. 0.13 ± 0.69 fL, P resistant and responder groups were 72.6% and 59.3%, respectively. After adjusting for traditional risk factors, the odds ratio in the clopidogrel resistant group with ΔMPV ≥0.2 fL was 4.10 (95% confidence interval; 1.84-9.17). In conclusion, ΔMPV was associated with PRU and PI%; a positive ΔMPV was an independent predictive marker for clopidogrel resistance after PCI.

Methods: Sixty-four patients with STEMI were randomized to PPCI + RIPostC (n=29 and PPCI (n=35 groups. RIPostC consisting of 4 cycles of 5 minutes occlusion/reperfusion by cuff inflation/deflation of the upper arm was started within 1 minute after the first balloon dilatation. Peripheral venous blood samples were collected before PPCI and at 0.5, 8, 24, 48, and 72 hours after PPCI to detect serum creatinine (SCr and creatine kinase-MB (CK-MB. Acute kidney injury (AKI rate and estimated glomerular filtration rate (eGFR were calculated. The transthoracic echocardiography was performed 7 days after PPCI to assess left ventricular ejection fraction (LVEF. Results: The patients in the PPCI + RIPostC group had a lower AKI rate compared with those in the PPCI group (P=0.04. The eGFR after PPCI increased in the PPCI + RIPostC group compared to the PPCI group (P<0.01. The peak of CK-MB concentration in the PPCI + RIPostC group was significantly lower than that in the PPCI group (P<0.01. The area under the curve of CK-MB decreased in the PPCI + RIPostC group compared with that in the PPCI group. LVEF in the PPCI + RIPostC group was significantly higher than that in the PPCI group (P=0.04.

The prognosis of patients with diabetes mellitus and chronic total occlusion (CTO treated with PCI is poorly investigated. Current study evaluates outcome of successful PCI on CTO in patients with and without diabetes. Methods: One hundred and sixty three patients treated with successful PCI on CTO between January 2009 and March 2011 were prospectively identified from the PCI registry at the Madani Heart Center, Tabriz, Iran. Patients were followed for 15±3 months, were evaluated for the occurrence of major adverse cardiac events (MACE comprising death, acute myocardial infarction, and need for repeat revascularization.Results: No differences were found in baseline clinical and procedural variables between patients with (n=34 and without diabetes (n=129, unless for hypertension (p=0.03. Hospitalization period after PCI in diabetics (3.26±0.61 days and non-diabetics (2.86±0.52 days was similar. In-hospital MACE occurred in 8 (23.5% individuals of diabetics and 10 (7.8% individuals of non-diabetics (p=0.02, among them revascularization was significantly higher in diabetics (20.6% vs. 7%, p=0.04.

    Mean platelet volume (MPV) is a well-established marker of platelet activation, and recent studies have shown that platelet activation is central to the processes in the pathophysiology of coronary artery disease (CAD). The study population consisted of 45 patients with stable CAD who underwent successful percutaneous coronary intervention (PCI) with drug-eluting stents. We selected 45 age- and sex-matched control subjects without cardiovascular diseases who did not require antiplatelet therapy. Hematological test was performed 3 times within 1 month before DAPT (baseline), at 2 weeks after PCI (post PCI) and at 9 months after PCI (follow-up). Compared to control subjects, MPV was significantly larger in patients with CAD (10.0 ± 0.6 vs 10.7 ± 0.8 fl, p < 0.01) although there was no significant difference in white blood cell count, hemoglobin, and platelet count between the 2 groups. In patients with CAD, DAPT did not affect platelet count (19.3 ± 4.8 × 10(4)-18.9 ± 4.6 × 10(4)/μl) or MPV (10.7 ± 0.8-10.5 ± 0.9 fl) during the follow-up period. MPV remained to be higher at follow-up in patients with CAD despite DAPT compared to control subjects (10.1 ± 0.7 vs 10.5 ± 0.9 fl, p < 0.05). Our data suggested that MPV might not be suitable for monitoring the effects of DAPT on platelet activity in patients with CAD undergoing PCI.

    The first purpose of this study was to reveal factors affecting the postoperative development of systemic inflammatory response syndrome (SIRS) in patients undergoing standard percutaneous nephrolithotomy (PNL) for renal stones. The second purpose was to determine the role of the preoperative platelet-to-lymphocyte ratio (PLR) and the neutrophil-to-lymphocyte ratio (NLR) in the prediction of SIRS.Matarials and Methods: In total, 192 patients who had undergone conventional PNL for renal stones from 2013 to 2015 were included in the study. SIRS developed postoperatively in 41 (21.3%) patients. The patients were divided into SIRS and non-SIRS groups, and the effects of the PLR, NLR, and other demographic and operative data were investigated to predict the development of SIRS. Variables significant in the univariate analysis were evaluated using a multiple logistic regression model to determine the independent risk factors for developing SIRS after PNL. Univariate analysis revealed significant differences in the preoperative PLR (P 114.1 because of the possibledevelopment of serious complications.

    The purpose of this study was to evaluate the results of treatment of superior vena cava syndrome (SVCS) in patients with benign and malignant disease using expandable metallic stent. From January 1995 to April 2000, 87 expandable stents were implanted in 82 patients (59 men, 23 women; mean age 57.8 years, age range 39-79 years) for the treatment of SVCS. The SVCS was defined as symptomatic bilateral obstruction of venous drainage from head, neck and upper extremities. In 68 patients SVCS was due to malignant neoplasia, and in 14 cases it was due to benign aetiology. All patients were treated with expandable stent. We implanted 81 Wallstent prostheses and 6 Palmaz stents. Adjuvant thrombolysis was applied in 12 patients who required fibrinolysis. After recanalization, the stent was implanted in all cases in SVC (infra- or supra-azygos vein). All patients were treated with heparin of low molecular weight (HBPM) during 6 months. Patency was analyzed according to clinical symptoms and Doppler US or venograms exploration. Technical success was observed in all cases. Clinical success was reached in 78 of 82 patients (95.1%) (absence of symptoms in 2 or 3 days). Four patients suffered immediate thrombosis which required fibrinolitic treatment with a new prosthesis placement in 1 case. The follow-up for the malignant process was of 7.1 months (range 1-39 months) and in benign cases was 31.2 months (range 11-61 months). Sixty-two (91.1%) patients with malignancy died without SVCS symptomatology. All the patients with benign pathology are alive. Clinical primary patency in malignant cases was 87% with assisted patency of 96.2%. Endovascular therapy using metallic stent and thrombolysis is a successful method to treat SVCS due to benign or malignant aetiology. (orig.)

    The failure of conservative treatment of chronic heel pain might cause prolonged disability from continued discomfort and pain, which mandates a further treatment modality. The presentation of the results of percutaneous fenestration of the anteromedial aspect of the calcaneus for symptomatic relief of resistant heel pain syndrome. Between September 2001 and August 2006, 34 patients (38 feet) with chronic heel pain syndrome reported an unacceptable level of pain despite intensive conservative treatment. There were 23 females and 11 males with an average age of 41 years (25-59 years). The average follow-up was 46 months (range, 14-84 months). Clinical evaluation of the intensity of pain (VAS score system), walking distance, standing duration, fascial tenderness, and ankle and subtalar joint motion were evaluated preoperatively and at regular follow-up. The preoperative pain score level was 8.4 (range, 6-10). The mean postoperative VAS for pain at 4 weeks was 5.89 (range, 3-9), at 8 weeks the value was 3.98 (range, 2-7), at 4 months 2.46 (range, 2-5), at 8 months 1.7 (range, 0-3) and at 12 months zero. A clinical improvement was seen in all patients irrespective of the duration of symptoms (p=0.0041). Three heels (7.9%) had partial relief of pain, but after 43 weeks had complete subsidence of pain. Complications include three transient paraesthesias at the distribution of the medial calcaneal nerve that resolved spontaneously after 8 weeks post-surgery. The results suggest the technique of percutaneous fenestration is a significantly effective treatment modality for patients with recalcitrant heel pain syndrome after failed conservative treatment. The described technique may provide a useful method for treating refractory heel spur syndrome without resorting to invasive surgical techniques and warrants further study.

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

    Bilateral adrenalectomy is currently the only available treatment for adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome (ectopic ACTH syndrome) that is refractory to pharmacologic therapy. We describe two patients with refractory ectopic ACTH syndrome who were treated with CT-guided percutaneous microwave ablation of both hyperplastic adrenal glands in a single session: One was not a surgical candidate, and the other had undergone unsuccessful surgery. Following the procedure, both patients achieved substantial decreases in serum cortisol, symptomatic improvement, and decreased anti-hypertensive medication requirements.

In this longitudinal study, we studied the prevalence of metabolic syndrome and its components in 190 patients who were undergoing intermittent ADT. The metabolic syndrome was defined according to the Adult Treatment Panel III criteria. All metabolic parameters, including lipid profile, blood glucose, blood pressures, and waist circumferences of the patients were measured six and 12 months after treatment. Mean age of the patients was 67.5 ± 6.74 years. The incidence of metabolic syndrome after six and 12 months was 6.8% and 14.7%, respectively. Analysis of various components of the metabolic syndrome revealed that patients had significantly higher overall prevalence of hyperglycemia, abdominal obesity, and hypertriglyceridemia in their six- and 12-month followups, but blood pressure has not been changed in the same period except for diastolic blood pressure after six months. Although there was an increased risk of metabolic syndrome in patients receiving intermittent ADT, it was lower than other studies that treated the same patients with continuous ADT. Also it seems that intermittent ADT has less metabolic complications than continuous ADT and could be used as a safe alternative in patients with advanced and metastatic PCa.

    Background: Stevens Johnson Syndrome and Erythema Multiforme are hypersensitivity skin reactions generally arising in the context of multiple causes. Radiation therapy is considered to be one of these causes, although most reports are hindered by concomitant medications. Aim: The aim of this paper was to present a case of Stevens Johnson Syndrome arising in a patient undergoing gynaecological brachytherapy with an unusual presentation. Case:We describe a case of a 56-year-old woman with endometrial cancer undergoing adjuvant gynaecological radiotherapy. While undergoing a gynaecological brachytherapy boost, she developed bilateral conjunctivitis that progressed to oral mucositis and pruritic erythema with sloughing of the skin on her arms and legs but not the torso or irradiated fields (namely the vaginal mucosa). Conclusion: This case illustrates the association of RT/SJS; however, it also raises the question of patients undergoing RT being more susceptible to SJS as opposed to a direct cause of the disease.

    Full Text Available OBJECTIVE: As almost any version of percutaneous nephrolithotomy (PCNL was safely and efficiently applied for adults as well as children without age being a limiting risk factor, the aim of the study was to compare the different characteristics as well as the efficacy, outcome, and safety of the pediatric and adult patients who had undergone mini-PCNL (MPCNL in a single institution. METHODS: We retrospective reviewed 331 renal units in children and 8537 renal units in adults that had undergone MPCNL for upper urinary tract stones between the years of 2000-2012. The safety, efficacy, and outcome were analyzed and compared. RESULTS: The children had a smaller stone size (2.3 vs. 3.1 cm but had smilar stone distribution (number and locations. The children required fewer percutaneous accesses, smaller nephrostomy tract, shorter operative time and less hemoglobin drop. The children also had higher initial stone free rate (SFR (80.4% vs. 78.6% after single session of MPCNL (p0.05. Both groups had low rate of high grade Clavien complications. There was no grade III, IV, V complications and no angiographic embolization required in pediatric group. One important caveat, children who required multiple percutaneous nephrostomy tracts had significant higher transfusion rate than in adults (18.8% vs. 4.5%, p = 0.007. CONCLUSIONS: This contemporary largest-scale analysis confirms that the stone-free rate in pediatric patients is at least as good as in adults without an increase of complication rates. However, multiple percutaneous nephrostomy tracts should be practiced with caution in children.

    Vitamin D deficiency has been consistently linked with cardiovascular diseases. However, results of intervention studies are contradictory. The aim of this study was to evaluate the effect of treatment with calcifediol (25(OH)D 3 ) on the cardiovascular system of patients with non-ST-elevation acute coronary syndrome after percutaneous coronary intervention. A prospective study assessing≥60-year-old patients with non-ST-elevation acute coronary syndrome, coronary artery disease and percutaneous revascularisation. We randomly assigned 41 patients (70.6±6.3 years) into 2 groups: Standard treatment+25(OH)D 3 supplementation or standard treatment alone. Major adverse cardiovascular events (MACE) were evaluated at the conclusion of the 3-month follow-up period. 25(OH)D levels were analysed with regard to other relevant analytical variables and coronary disease extent. Basal levels of 25(OH)D≤50nmol/L were associated with multivessel coronary artery disease (RR: 2.6 [CI 95%:1.1-7.1], P=.027) and 25(OH)D≤50nmol/L+parathormone ≥65pg/mL levels correlated with increased risk for MACE (RR: 4 [CI 95%: 1.1-21.8], P=.04]. One MACE was detected in the supplemented group versus five in the control group (P=.66). Among patients with 25(OH)D levels≤50nmol/L at the end of the study, 28.6% had MACE versus 0% among patients with 25(OH)D>50nmol/L (RR: 1,4; P=.037). Vitamin D deficiency plus secondary hyperparathyroidism may be an effective predictor of MACE. A trend throughout the follow up period towards a reduction in MACE among patients supplemented with 25(OH)D 3 was detected. 25(OH)D levels≤50nmol/L at the end of the intervention period were significantly associated with an increased number of MACE, hence, 25(OH)D level normalisation could improve cardiovascular health in addition to bone health.

    Acute kidney injury (AKI), a common and crucial complication of acute coronary syndrome (ACS) after receiving percutaneous coronary intervention (PCI), is associated with increased mortality and adverse outcomes. This study aimed to develop and validate a risk prediction model for incident AKI after PCI for ACS. We included 82,186 patients admitted for ACS and receiving PCI between 1997 and 2011 from the Taiwan National Health Insurance Research Database and randomly divided them into a training cohort (n = 57,630) and validation cohort (n = 24,656) for risk model development and validation, respectively. Risk factor analysis revealed that age, diabetes mellitus, ventilator use, prior AKI, number of intervened vessels, chronic kidney disease (CKD), intra-aortic balloon pump (IABP) use, cardiogenic shock, female sex, prior stroke, peripheral arterial disease, hypertension, and heart failure were significant risk factors for incident AKI after PCI for ACS. The reduced model, ADVANCIS, comprised 8 clinical parameters (age, diabetes mellitus, ventilator use, prior AKI, number of intervened vessels, CKD, IABP use, cardiogenic shock), with a score scale ranging from 0 to 22, and performed comparably with the full model (area under the receiver operating characteristic curve, 87.4% vs 87.9%). An ADVANCIS score of ≥6 was associated with higher in-hospital mortality risk. In conclusion, the ADVANCIS score is a novel, simple, robust tool for predicting the risk of incident AKI after PCI for ACS, and it can aid in risk stratification to monitor patient care.

    Objective: To evaluate the clinical value of percutaneous transluminal angioplasty with stenting (PTAS) for the treatment of superior vana cava obstructive syndrome (SVCOS). Methods: 15 cases of SVCOS including 10 cases of lung cancer with mediastinal lymphatic metastasis, 3 cases as malignant lymphoma and 2 cases of esophageal cancer with mediastinal lymphadenopathy, were undergone right subclavian vein or elbow vein catheterization for pressure measurement and DSA imaging of SVC with displaying the obstructive characteristics. A self-expanding stent was then implanted through right femoral vein catheterization. Results: 15 cases were all successfully under-taken angioplasty and stenting, except 1 case with a long stricture over 10 cm requiring 2 stents. After successful stent placement, DSA revealed smooth flow of contrast with almost normal diameter of SVC lumen, together with disappearance or relief of SVCOS. The SVC pressure decreased from 30.5±2.3 cmH 2 O down to 8.8 ± 1.5 cmH 2 O after recanalization, with a significant difference in statistics (P<0.01). All the patients were followed up for 6 months and obstructive symptom did not reappear except one case complicated with thrombosis which was treated by regional thrombolysis and balloon dilation leading to obviously improved symptom. Conclusion: PTAS for the treatment of SVCOS is effective, safe, simple and of less complications. (authors)

    Objective: To investigate the feasibility and effect of recanalization of inferior vena cava with percutaneous transluminal angioplasty(PTA)by Inoue-balloon. Methods: Eighty-nine patients with Budd-chiari syndrome (BCS )were treated with PTA by Inoue-balloon. Results: After PTA, the median (interquartile range)diameter of hepatic segment inferior vena cava increased from 0.00 (0.20-0.00) cm to 1.90 (2.00 1.47)cm; (P < 0.001), and the mean pressure of inferior vena cava reduced from (20.63 ± 7.22) mmHg to (12.13 ± 5.60) mmHg; (P < 0.001); with only less serious complications as rupture in two cases and without need of prior minor diameter balloon dilation in Inoue-balloon PTA. Conclusion: The advantages of Inoue- balloon PTA for BCS are more reliable and facile than those of polyethylene balloon, and may take the place in the foreseen future. (authors)

    Von Willebrand disease (vWD) results from quantitative or qualitative deficiency of von Willebrand factor (vWF). The occurrence of myocardial infarction is very rare in patients with vWD. A few case reports of acute coronary syndrome (ACS) in vWD patients are present in the literature, but no definite management recommendations are available for such patients. We report a case of successful percutaneous coronary intervention (PCI) with bare-metal stent (BMS) implantation in a 46-year-old woman with type 1 vWD and history of coronary artery disease (CAD). She received periprocedural dual-antiplatelet therapy for 2 weeks and then continued aspirin without any bleeding complications. The optimal management of patients with vWD and ACS is complex and presents a therapeutic challenge. We propose that dual-antiplatelet therapy can be used safely in most vWD patients presenting with ACS as most of them are type 1 vWD. PCI with BMS can be done safely. Long-term management of these patients requires a systemic approach including hematological consultation, ascertaining vWF levels, as well as patient education and close outpatient follow-up.

    To assess the effectiveness of percutaneous tibial nerve stimulation (PTNS) on adult patients with overactive bladder syndrome, using a systematic review of randomized controlled trials (RCTs), clinical controlled trials (CCTs), and prospective observational cohort studies. A computer-aided literature search was performed in: PubMed, EMBASE and CENTRAL (2000 to November 15, 2011) to identify RCTs, CCTs, and prospective observational cohort studies. The study had to investigate the effect of PTNS on overactive bladder syndrome. The methodological quality of each study was assessed and a qualitative analysis was performed to establish the levels of evidence. Four RCTs and six prospective observational cohort studies were identified. There is strong evidence for the efficacy of PTNS versus a sham treatment. There is limited evidence that the use of PTNS and tolterodine ER is equally effective. No additional effect of a combination of Stoller afferent nerve stimulation (SANS) and anticholinergic medication compared to SANS alone. Most cohort studies suggested decreased frequency and improvement of incontinence and nocturia. However, the level of evidence was insufficient to make any firm conclusions. Because the total duration of all included trials varied between 6 and 12 weeks, so far there is little information on treatment periods. PTNS is efficacious for frequency and urgency urinary incontinence. More high quality studies are needed to improve the level of evidence concerning the efficacy of PTNS with regard to urgency and nocturia, to specify patient selection criteria, optimal treatment modalities and long-term effects as well as the effectiveness in more pragmatic trials.

    occlusion of the cannulated artery was demonstrated in 6.4% of patients. Ultrasound imaging is a reliable method to evaluate the diameter of forearm arteries and track their course in patients undergoing invasive cardiovascular procedures via radial artery access. The diameter of the radial artery by ultrasound evaluation is larger compared to that of the ulnar artery. The diameter of forearm arteries in women is smaller compared to men. A dilatation of the radial artery which may last up to 12 months develops following its percutaneous cannulation. Ultrasound imaging allows detection and monitoring of local complications such as radial artery occlusion. An unfavourable ratio of blood vessel diameter to the size of the used introducer sheath is a predictor of radial artery occlusion. Ultrasound imaging enables reliable evaluation of vascular anomalies involving the radial artery, especially within the distal forearm.

    To study the frequency of restless legs syndrome in patients of end stage renal disease undergoing maintenance hemodialysis. Design: Cross sectional descriptive study. Place and Duration of Study: Department of medicine, CMH Multan from Nov 2010 to April 2011. Patients and Methods: One hundred and ninety four (n=194) patients of End stage renal disease who had been on maintenance hemodialysis for at least 3 months, were included in the study after full informed consent and using consecutive sampling. Patients having dementia, psychiatric illness, pregnancy, hypothyroidism, Parkinson's disease and alcoholics were excluded from the study. Patients who fulfilled all four diagnostic criteria for restless legs syndrome as proposed by International restless legs syndrome study group (IRLSSG), by direct questioning were diagnosed as having restless legs syndrome. Results: The frequency of restless legs syndrome was found to be 12.4% in patients undergoing hemodialysis (10.5% in males versus 16% in females). The mean duration of hemodialysis was higher among RLS positive patients (12.88 +- 5.543 months) as compared to RLS negative patients (6.94 +- 4.610 months). Conclusion: RLS is a frequent, under-diagnosed co-morbidity in patients undergoing maintenance hemodialysis. (author)

    Full Text Available Objective. We aimed to investigate the effect of peritubal local anesthetic and opioid infiltration on pain scores and analgesic consumption in patients who underwent percutaneous nephrolithotomy. Material and Methods. Patients aged between 18 and 65 years and ASA I-III were included in this double-blind, randomized study. The patients were divided into two groups. All patients underwent spinoepidural anesthesia. 20 mL of 0.25 percent bupivacaine + 5 mg morphine (0.5 mL, in Group P (n=66, infiltrated the renal capsule, perinephric fat, muscles, subcutaneous tissue, and skin under fluoroscopy. In Group C (n=64, none of the patients received a peritubal injection. In the first 24 h pain scores, time of the first analgesic demand, the mean number of analgesic demands, and postoperative complications were compared between groups. Results. The mean VAS score at postoperative 8, 12, and 24 h and dynamic VAS score at postoperative 4, 8, 12, and 24 h were significantly lower in Group P. VAS score at postoperative 4 h was not significant. Time of the first analgesic demand was significantly longer in Group P. Conclusion. Our study results suggest that peritubal infiltration of bupivacaine with morphine after percutaneous nephrolithotomy is an effective method for postoperative pain control and reduces analgesic consumption.

    Post lumbar surgery syndrome or failed back surgery syndrome with persistent pain continues to increase over the years. The speculated causes of post lumbar laminectomy syndrome include acquired stenosis, epidural fibrosis, arachnoiditis, radiculopathy, and recurrent disc herniation. Epidural fibrosis may account for as much as 20% to 36% of all cases of failed back surgery syndrome. Percutaneous epidural adhesiolysis has been employed in interventional pain management in the treatment of chronic, refractory low back and lower extremity pain after back surgery. A systematic review of randomized trials and observational studies. To evaluate the effectiveness of percutaneous adhesiolysis in managing chronic low back and lower extremity pain due to post lumbar surgery syndrome. A comprehensive literature search was conducted utilizing electronic databases, as well as systematic reviews and cross references from 1966 through December 2008. The quality of individual articles used in this analysis was assessed by modified Cochrane review criteria for randomized trials and the Agency for Healthcare Research and Quality (AHRQ) criteria for assessment of observational studies. Clinical relevance was evaluated using 5 questions according to the criteria recommended by the Cochrane Review Back Group. Analysis was conducted using 5 levels of evidence, ranging from Level I to III, with 3 subcategories in Level II. The primary outcome measure was pain relief (short-term relief of at least 6 months and long-term relief of more than 6 months). Secondary outcome measures were improvement in functional status, psychological status, return to work, and change in opioid intake. Of the 13 studies considered for inclusion, 3 randomized trials and 4 observational studies met the inclusion criteria for methodologic quality assessment and evidence synthesis based on methodologic quality scores of 50 or more.

    Impaired quality of life and psychological distress are common in irritable bowel syndrome (IBS) and may be associated with unhelpful cognitions. Hypnotherapy (HT) is effective in improving both symptoms and quality of life in patients with IBS, and this study was designed to determine whether this improvement is reflected in cognitive change using a validated scale recently developed for use in such patients. A total of 78 IBS patients completed a validated symptom-scoring questionnaire, the Hospital Anxiety and Depression (HAD) Scale and the Cognitive Scale for Functional Bowel Disorders (FBDs), before and after 12 sessions of gut-focused HT. HT resulted in improvement of symptoms, quality of life and scores for anxiety and depression (all P'scognitions also improved, with reduction in the total cognitive score (TCS; PCognitions were related to symptom severity because the most abnormal cognitive scores were observed in patients with the highest symptom scores (Pcognitive score (Pcognitive score had independence from the other scores and did not serve solely as a proxy for symptom improvement. This study shows that symptom improvement in IBS with HT is associated with cognitive change. It also represents an initial step in unravelling the many possible mechanisms by which treatments such as HT might bring about improvement.

    Full Text Available Background and aim: Patients undergoing percutaneous endoscopic gastrostomy (PEG tube placement often are under antiplatelet therapy with a potential thromboembolic risk if these medications are discontinued. This systematic review aims to assess if maintaining aspirin and/or clopidogrel treatment increases the risk of bleeding following PEG placement. Methods: A systematic search of the MEDLINE, EMBASE, and SCOPUS databases was developed for studies investigating the risk of bleeding in patients on antiplatelet therapy undergoing PEG tube insertion. Summary estimates, including 95 % confidence intervals (CI, were calculated. A fixed or random effects model was used depending on heterogeneity (I². Publication bias risks were assessed by means of funnel plot analysis. Results: Eleven studies with a total of 6,233 patients (among whom 3,665 were undergoing antiplatelet treatment, met the inclusion criteria and were included in the quantitative summary. Any PEG tube placement-related bleeding was found in 2.67 % (95 % CI 1.66 %, 3.91 % of the entire population and in 2.7 % (95 % CI 1.5 %, 4.1 % of patients not receiving antiplatelet therapy. Pooled relative risk (RR for bleeding in patients under aspirin, when compared to controls, was 1.43 (95 % CI 0.89, 2.29; I² = 0 %; pooled RR for clopidogrel was 1.21 (95 % CI 0.48, 3.04; I² = 0 % and for dual antiplatelet therapy, 2.13; (95 % CI 0.77, 5.91; I² = 47 %. No significant publication bias was evident for the different medications analyzed. Conclusion: Antiplatelet therapy was safe among patients undergoing PEG tube insertion. Future prospective and randomized studies with larger sample sizes are required to confirm the results of this study.

    Postural orthostatic tachycardia syndrome is characterized by orthostatic intolerance. Orthostasis (or other mild physical stress) triggers a cascade of inappropriate tachycardia, lightheadedness, palpitations, and often fainting. The underlying defect is sympathetic dysregulation of the heart, which receives its sympathetic tone from the cervical and upper thoracic sympathetic ganglia. Primary hyperhidrosis is also thought to be the result of sympathetic dysregulation. We present the case of a patient treated with CT-guided, percutaneous T2 EtOH sympatholysis for craniofacial hyperhidrosis. The patient also suffered from postural orthostatic tachycardia syndrome for many years and was unresponsive to treatment. Immediately after sympatholysis, the patient experienced resolution of both craniofacial hyperhidrosis and postural orthostatic tachycardia syndrome.

    To examine the effect of abciximab treatment on intensive care length of stay for patients undergoing percutaneous coronary intervention (PCI). A retrospective study conducted in a naturalistic setting. A 2-stage econometric model was used to control for the influence of possible selection bias across categories of patients and for both observable and unobservable factors correlated with each patient's treatment selection and length of stay in intensive care. Multivariate analysis was applied to control for a wide range of factors (patient demographics, insurance provider, health conditions, admission and discharge information, and hospital characteristics) that may influence intensive care length of stay. Retrospective data were obtained from HCIA's Clinical Pathways Database. Patients (n = 13,364) who were hospitalised in any of 87 hospitals across the US over the period from October 1, 1995 to December 1, 1996. After controlling for high-risk indications and selection bias, results indicated that administration of abciximab was associated with a significantly shorter length of stay in intensive care compared with not administering a GPIIb/IIIa inhibitor (0.45 fewer days; p < or = 0.0001). In a subgroup analysis of patients having an acute myocardial infarction (n = 4793), administration of abciximab was also associated with a significantly shorter intensive care stay (0.27 fewer days; p < 0.0001). Results of this study indicate that the administration of abciximab is associated with a reduction in the length of stay in intensive care. This reduction implies potential cost offsets for patients undergoing PCI who receive abciximab.

Thus, we aimed to assess the predictive value of various established and emerging biomarkers for major adverse cardiovascular events (MACE in these patients.Thirty-four patients with symptomatic severe mitral valve insufficiency with a mean STS-Score for mortality of 12.6% and a mean logistic EuroSCORE of 19.7% undergoing MitraClip therapy were prospectively included in this study. Plasma concentrations of mid regional-proatrial natriuretic peptide (MR-proANP, Cystatin C, high-sensitive C-reactive protein (hsCRP, high-sensitive troponin T (hsTnT, N-terminal B-type natriuretic peptide (NT-proBNP, galectin-3, and soluble ST-2 (interleukin 1 receptor-like 1 were measured directly before procedure. MACE was defined as cardiovascular death and hospitalization for heart failure (HF.During a median follow-up of 211 days (interquartile range 133 to 333 days, 9 patients (26.5% experienced MACE (death: 7 patients, rehospitalization for HF: 2 patients. Thirty day MACE-rate was 5.9% (death: 2 patients, no rehospitalization for HF. Baseline concentrations of hsTnT (Median 92.6 vs 25.2 ng/L, NT-proBNP (Median 11251 vs 1974 pg/mL and MR-proANP (Median 755.6 vs 318.3 pmol/L, all p<0.001 were clearly higher in those experiencing an event vs event-free patients, while other clinical variables including STS-Score and logistic EuroSCORE did not differ significantly. In Kaplan-Meier analyses, NT-proBNP and in particular hsTnT and MR-proANP above the median discriminated between those experiencing an event vs event-free patients. This was further corroborated by C-statistics where areas under the ROC curve for prediction of MACE using the respective median values were 0.960 for MR-proANP, 0.907 for NT-proBNP, and 0.822 for hsTnT.MR-proANP and hsTnT strongly

    Percutaneous tibial nerve stimulation (PTNS) is an established treatment for overactive bladder (OAB), especially in women with other concomitant pelvic disorders, such as sexual impairment. To evaluate the impact of PTNS on female sexual dysfunction (FSD) in women undergoing PTNS for OAB and analyze the results. An observational prospective study was conducted in two Italian centers. Consecutive women undergoing PTNS for dry OAB were enrolled from May 2013 to June 2014. All patients were asked to complete the Female Sexual Function Index (FSFI), the OAB short-form questionnaire, and a 24-hour bladder diary at baseline and 3 months later, at the end of the PTNS course. Patients with an FSFI total score no higher than 26.55 at inclusion were considered as presenting with FSD. Patients with an FSFI total score higher than 26.55 after treatment (if the increase in FSFI score was ≥20%) were considered FSD objective responders. Sexuality was assessed using the FSFI. The 24-hour bladder diary and completed OAB short-form questionnaire were assessed before and after PTNS to evaluate OAB symptoms. Forty-one women were evaluable. Twenty-one of 41 women (51%; mean age = 51 ± 10.67 years) were considered affected by FSD at inclusion. All FSFI domains showed statistically significant improvement in women with FSD (P < .05). In particular, 9 of 21 patients with FSD (43%) objectively responded (before treatment: mean FSFI total score = 18.11, range 10.8-26.3; after treatment: mean FSFI total score = 31.04, range 27.6-35). Also, women without FSD at baseline reported statistically significant improvement in their sexual function based on FSFI scores (P < .05). No significant correlations were seen between data questionnaires. PTNS improves sexual function in women with dry OAB. This amelioration is independent of urinary symptoms. Further studies are needed to confirm a possible role of PTNS in treating FSD. Copyright © 2016 International Society for Sexual Medicine

    Full Text Available Rhabdomyolysis is the result of skeletal muscle tissue injury and is characterized by elevated creatine kinase levels, muscle pain, and myoglobinuria. It is caused by crush injuries, hyperthermia, drugs, toxins, and abnormal metabolic states. This is often difficult to diagnose perioperatively and can result in renal failure and compartment syndrome if not promptly treated. We report a rare case of inadvertent rhabdomyolysis and compartment syndrome in a bodybuilder undergoing minimally invasive cardiac surgery. The presentation, differential diagnoses, and management are discussed. Hyperkalemia may be the first presenting sign. Early recognition and management are essential to prevent life-threatening complications.

    Full Text Available Stroke is a rare but serious adverse event associated with percutaneous coronary intervention (PCI. However, the relative risk of stroke between stable patients undergoing a direct PCI strategy and those undergoing an initial optimal medical therapy (OMT strategy has not been established yet. This study sought to investigate if, in patients with stable coronary artery disease (SCAD, an initial strategy PCI is associated with a higher risk of stroke than a strategy based on OMT alone.We performed a meta-analysis of 6 contemporary randomized control trials in which 5673 patients with SCAD were randomized to initial PCI or OMT. Only trials with stent utilization more than 50% were included. Study endpoint was the rate of stroke during follow up.Mean age of patients ranged from 60 to 65 years and stent utilization ranged from 72% to 100%. Rate of stroke was 2.0% at a weighted mean follow up of 55.3 months. On pooled analysis, the risk of stroke was similar between patients undergoing a PCI plus OMT and those receiving only OMT (2.2% vs. 1.8%, OR on fixed effect = 1.24 95%CI: 0.85-1.79. There was no heterogeneity among the studies (I2 = 0.0%, P = 0.15. On sensitivity analysis after removing each individual study the pooled effect estimate remains unchanged.In patients with SCAD an initial strategy based on a direct PCI is not associated with an increased risk of stroke during long-term follow up compared to an initial strategy based on OMT alone.

    We aimed to perform a gender-based meta-analysis of the outcome of bivalirudin versus heparin in patients undergoing percutaneous coronary interventions (PCI). Bivalirudin has been shown to decrease major bleeding when compared to heparin ± glycoprotein IIb/IIIa inhibitors (GPI) in patients undergoing PCI. It is unclear, however, if those differences in outcomes are the same for men and women. We included randomized controlled trials (RCTs) that compared bivalirudin to heparin with or without GPI in patients undergoing PCI and reported outcome data that were stratified by gender. Random effect model was used to pool odds ratio (OR) and 95% confidence intervals (CI). We included 9 trials with 33,224 patients. Bivalirudin decreased major bleeding when compared to heparin plus routine GPI in both men (OR: 0.51, P < 0.001) and women (OR: 0.55, P < 0.001). However, when GPI were used selectively with heparin, the bleeding lowering effect of bivalirudin was statistically significant in men (OR: 0.69, P = 0.02) but not in women (OR: 0.71, P = 0.21). When compared to heparin ± GPI, there was a nonstatistically significant trend toward lower all-cause mortality with bivalirudin in both men (OR: 0.76, P = 0.055) and women (OR: 0.79, P = 0.21). There were no significant differences in major adverse cardiovascular events between heparin and bivalirudin in both men and women. Bivalirudin decreases major bleeding in both men and women when compared to heparin plus routine GPI. However, when compared to heparin alone, the bleeding lowering benefit of bivalirudin is less evident in women. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Recently, concurrent chemoradiotherapy (CCRT) is frequently used for the treatment of oropharyngeal cancer. However, CCRT induces mucositis and dysphagia and causes inadequate oral nutrition intake. Thus, percutaneous endoscopic gastrostomy (PEG) in advance is recently recommended. To evaluate the effectiveness of PEG on nutritional intake, nutritional status, blood test, and grade of mucositis of 29 patients who had CCRT with PEG were investigated retrospectively. The results were statistically compared with those of 13 patients who had CCRT without PEG as a control group. Regarding the total energy, no significant change was observed in the PEG group, while the total energy intake significantly decreased in the control group (P=0.026). A significant correlation was observed between the rate of body weight loss during CCRT and total energy intake (R=0.78). The total energy intake of patients who could maintain body weight was 34.1 kcal/kg/day. Taken together, these results suggested that early nutritional administration using PEG can reduce the weight loss during CCRT. (author)

    To evaluate the effects of sex and anthropometry on clinical outcomes in patients who underwent percutaneous coronary intervention (PCI). From three randomized trials (REal Safety and Efficacy of 3-month dual antiplatelet Therapy following Endeavor zotarolimus-eluting stent implantation, Impact of intraVascular UltraSound guidance on outcomes of Xience Prime stents in Long lesions, Chronic Total Occlusion InterVention with drUg-eluting Stents), we compared 333 pairs of men and women matched by propensity scores, all of whom underwent intravascular ultrasound (IVUS)-guided PCI for complex lesions. For 12 months, the incidence of adverse cardiac events, defined as the composite of cardiac death, target lesion-related myocardial infarction, and target lesion revascularization, was not different between women and men (2.4% vs. 2.4%, p=0.939). Using multivariable Cox's regression analysis, post-intervention minimum lumen area [MLA; hazard ratio (HR)=0.620, 95% confidence interval (CI)=0.423-0.909, p=0.014] by IVUS was a predictor of adverse cardiac events. Height on anthropometry and lesions with chronic total occlusion were significantly related to post-intervention MLA. However, female sex was not independently associated with post-intervention MLA. In an age and sex-adjusted model, patients in the low tertile of height exhibited a greater risk for adverse cardiac events than those in the high tertile of height (HR=6.391, 95% CI=1.160-35.206, p=0.033). Sex does not affect clinical outcomes after PCI for complex lesions. PCI outcomes, however, may be adversely affected by height.

    This study was conducted to determine the association between radial access, guided femoral access, and non-guided femoral access on postprocedural bleeding and vascular complications after percutaneous coronary intervention (PCI). Bleeding events and major vascular complications after PCI are associated with increased morbidity, mortality, and cost. While the radial approach has been shown to be superior to the femoral approach in reducing bleeding and vascular complications, whether the use of micropuncture, fluoroscopy, or ultrasound mitigates these differences is unknown. We conducted a post hoc analysis of women in the SAFE-PCI for Women trial who underwent PCI and had the access method identified (n = 643). The primary endpoint of postprocedure bleeding or vascular complications occurring within 72 hours or at discharge was adjudicated by an independent clinical events committee and was compared based on three categories of access technique: radial, guided femoral (fluoroscopy, micropuncture, ultrasound), or non-guided femoral (none of the aforementioned). Differences between the groups were determined using multivariate logistic regression using radial access as the reference. Of the PCI population, 330 underwent radial access, 228 underwent guided femoral access, and 85 underwent non-guided femoral access. There was a statistically significant lower incidence of the primary endpoint with radial access vs non-guided femoral access; however, there was no significant difference between radial approach and femoral access guided by fluoroscopy, micropuncture, or ultrasound. This post hoc analysis demonstrates that while radial access is safer than non-guided femoral access, guided femoral access appears to be associated with similar bleeding events or vascular complications as radial access.

    Percutaneous coronary intervention (PCI) is the most effective reperfusion modality in patients with acute myocardial infarction (MI). Data concerning long-term survival and functional outcome are sparse. One thousand consecutive patients treated by emergency PCI were systematically ana-lysed in a single-centre registry. Multivariate predictors of in-hospital mortality, post-discharge mortality and late functional capacity were identified. Follow-up was completed for 978 patients. The median clinical follow-up length was 3.2 years. In-hospital and post-discharge mortality were 7.6% and 7.3%, respectively. Annualised post-discharge mortality remained stable over time at 2% per year. Independent predictors of in-hospital death were cardiogenic shock, TIMI flow 6 h. Independent predictors of post-discharge mortality were TIMI flow after PCI <3, prior MI, elevated glucose levels at admission, and increasing age. In contrast, cardiogenic shock, time to patent artery and left ventricular ejection fraction <40% were not independently associated with post-hospital death. At late follow-up, 47% of patients had normal functional capacity and 49.1% were in New York Heart Association functional class II. Predictors of impaired functional capacity at follow-up were age, gender, smoking habits and multivessel coronary disease. Post-discharge mortality after PCI for acute MI was 2% per year. Significant differences exist between predictors of in-hospital and post-discharge mortality. The functional capacity of surviving patients was remarkably good, even when presented in cardiogenic shock.

    Background Evidence suggests that high-dose statin pretreatment may reduce the risk of periprocedural myocardial infarction (PMI) and major adverse cardiac events (MACE) for certain patients; however, previous analyses have not considered patients with a history of statin maintenance treatment. In this meta-analysis of randomized controlled trials (RCTs), we reevaluated the efficacy of short-term high-dose statin pretreatment to prevent PMI and MACE in an expanded set of patients undergoing elective percutaneous coronary intervention. Methods We searched the PubMed/Medline database for RCTs that compared high-dose statin pretreatment with no statin or low-dose statin pretreatment as a prevention of PMI and MACE. We evaluated the incidence of PMI and MACE, including death, spontaneous myocardial infarction, and target vessel revascularization at the longest follow-up for each study for subgroups stratified by disease classification and prior low-dose statin treatment. Results Twenty-four RCTs with a total of 5,526 patients were identified. High-dose statin pretreatment was associated with 59% relative reduction in PMI (odds ratio [OR]: 0.41; 95% confidence interval [CI]: 0.34–0.49; Pstatin pretreatment on MACE was significant for statin-naive patients (OR: 0.69; 95% CI: 0.50–0.95; P = 0.02) and prior low dose statin-treated patients (OR: 0.28; 95% CI: 0.12–0.65; P = 0.003); and for patients with acute coronary syndrome (OR: 0.52; 95% CI: 0.34–0.79; P = 0.003), but not for patients with stable angina (OR: 0.71; 95% CI 0.45–1.10; P = 0.12). Long-term effects on survival were less obvious. Conclusions High-dose statin pretreatment can result in a significant reduction in PMI and MACE for patients undergoing elective PCI. The positive effect of high-dose statin pretreatment on PMI and MACE is significant for statin-naïve patients and patients with prior treatment. The positive effect of high-dose statin pretreatment on MACE is significant for

    In ST-segment elevation myocardial infarction (STEMI), QRS score at presentation ECG may reflect the progression of infarction and facilitate prediction of the degree of myocardial salvage achieved by reperfusion therapy.Methods and Results:Admission electrocardiogram (ECG) was studied in 2,607 patients with STEMI undergoing primary percutaneous coronary intervention (PCI) within 24 h of symptom onset. Patients were classified into 3 groups according to QRS score: low (0-3, n=1,227), intermediate (4-7, n=810), and high (≥8, n=570). An increase of infarct size estimated by median peak creatine phosphokinase was observed as QRS score increased (low score, 1,836 IU/L; inter-quartile range (IQR), 979-3,190 IU/L; intermediate score, 2,488 IU/L; IQR, 1,126-4,640 IU/L; high score, 3,454 IU/L; IQR, 1,759-5,639 IU/L; P<0.001). Higher QRS score was associated with higher long-term mortality (low, intermediate, and high score, 15.6%, 19.7%, and 23.7% at 5 years, respectively; log-rank P<0.001). The positive relationship of QRS score with mortality was consistently seen when stratified by infarct location. The association of high QRS score with increased mortality was most remarkably seen in patients with early (≤2 h) presentation (low, intermediate, and high score: 16.7%, 16.6%, and 28.1% at 5 years, respectively; log-rank P<0.001). Higher QRS score at presentation ECG was associated with larger infarct size, and higher long-term mortality in patients with STEMI undergoing primary PCI. QRS score appears to be important in the early risk stratification for STEMI.

    Full Text Available Background: Myocardial blush grade (MBG, thrombolysis in myocardial infarction (TIMI and corrected TIMI frame count (cT F C are indices of successful angiographic reperfusion. This study sought to determine the predictors of angiographically successful reperfusion including demographic, clinical and angiographic factors in patients with ST elevation myocardial infarction (STEMI undergoing primary percutaneous coronary intervention (pPCI. Materials and Methods: A cross-sectional study of patients with a confirmed diagnosis of STEMI undergoing pPCI was designed. Eligible patients referring to a university heart center were enrolled in the study from March 2012 to December 2012. Successful epicardial reperfusion was defned as TIMI flow grade 3 or cTFC<= 28 frames and successful myocardial reperfusion as MBG 2 or 3. Results: The study population consisted of 100 patients, including 74 males and 26 females, with mean ± standard deviation age of 58.27 ± 11.60 years. Achieving open microvasculature (MBG 2/3 was positively associated with a history of nitrate intake (P = 0.03 and history of calcium channel blocker (CCB intake (P = 0.005. Hyperglycemia was inversely associated with achieving a final cTFC ≤ 28 frames (r = −0.32, P = 0.001. Conclusions: Our findings suggest that patients with a history of nitrate and CCB intake had a higher likelihood of successful PCI. In addition, patients with a higher blood glucose level on admission may have a reduced rate of reperfusion success. Future studies with a larger sample size are recommended to investigate the significant relationships observed in this study.

    2010-02-01

    Full Text Available Abstract Background Clinical trials comparing thrombectomy devices with conventional percutaneous coronary interventions (PCI in patients with acute ST elevation myocardial infarction (STEMI have produced conflicting results. The objective of our study was to systematically evaluate currently available data comparing thrombectomy followed by PCI with conventional PCI alone in patients with acute STEMI. Methods Seventeen randomized trials (n = 3,909 patients of thrombectomy versus PCI were included in this meta-analysis. We calculated the summary odds ratios for mortality, stroke, post procedural myocardial blush grade (MBG, thrombolysis in myocardial infarction (TIMI grade flow, and post procedural ST segment resolution (STR using random-effects and fixed-effects models. Results There was no difference in risk of 30-day mortality (44/1914 vs. 50/1907, OR 0.84, 95% CI 0.54-1.29, P = 0.42 among patients randomized to thrombectomy, compared with conventional PCI. Thrombectomy was associated with a significantly greater likelihood of TIMI 3 flow (1616/1826 vs. 1533/1806, OR 1.41, P = 0.007, MBG 3 (730/1526 vs. 486/1513, OR 2.42, P Conclusions Thrombectomy devices appear to improve markers of myocardial perfusion in patients undergoing primary PCI, with no difference in overall 30-day mortality but an increased likelihood of stroke. The clinical benefits of thrombectomy appear to be influenced by the device type with a trend towards survival benefit with MAT and worsening outcome with mechanical devices.

    Full Text Available OBJECTIVES: Reduced number and impaired function of circulating endothelial progenitor cells (EPCs in patients with chronic kidney disease have been reported. However, there is little data about the association between circulating EPC levels and risk of contrast-induced nephropathy (CIN. The aim of this study was to investigate the relationship between circulating EPCs and CIN in patients after angiography. METHODS AND RESULTS: A total of 77 consecutive patients undergoing elective percutaneous coronary intervention (PCI and percutaneous transluminal angioplasty (PTA were enrolled. Flow cytometry with quantification of EPC markers (defined as CD34+, CD34+KDR+, and CD34+KDR+CD133+ in peripheral blood samples was used to assess EPC number before the procedure. CIN was defined as an absolute increase ≧0.5 mg/dl or a relative increase ≧25% in the serum creatinine level at 48 hours after the procedure. Eighteen (24% of the study subjects developed CIN. Circulating EPC levels were significantly lower in patients who developed CIN than in those without CIN (CD34+KDR+, 4.11±2.59 vs. 9.25±6.30 cells/105 events, P<0.001. The incidence of CIN was significantly greater in patients in the lowest EPC tertile (CD34+KDR+; from lowest to highest, 52%, 15%, and 4%, P<0.001. Using univariate logistic regression, circulating EPC number (CD34+KDR+ was a significant negative predictor for development of CIN (odds ratio 0.69, 95% CI 0.54-0.87, P = 0.002. Over a two-year follow-up, patients with CIN had a higher incidence of major adverse cardiovascular events including myocardial infarction, stroke, revascularization of treated vessels, and death (66.7% vs. 25.4%, P = 0.004 than did patients without CIN. CONCLUSIONS: Decreased EPC level is associated with a greater risk of CIN, which may explain part of the pathophysiology of CIN and the poor prognosis in CIN patients.

    Full Text Available BACKGROUND: Transfusion is a common complication of Percutaneous Coronary Intervention (PCI and is associated with adverse short and long term outcomes. There is no risk model for identifying patients most likely to receive transfusion after PCI. The objective of our study was to develop and validate a tool for predicting receipt of blood transfusion in patients undergoing contemporary PCI. METHODS: Random forest models were developed utilizing 45 pre-procedural clinical and laboratory variables to estimate the receipt of transfusion in patients undergoing PCI. The most influential variables were selected for inclusion in an abbreviated model. Model performance estimating transfusion was evaluated in an independent validation dataset using area under the ROC curve (AUC, with net reclassification improvement (NRI used to compare full and reduced model prediction after grouping in low, intermediate, and high risk categories. The impact of procedural anticoagulation on observed versus predicted transfusion rates were assessed for the different risk categories. RESULTS: Our study cohort was comprised of 103,294 PCI procedures performed at 46 hospitals between July 2009 through December 2012 in Michigan of which 72,328 (70% were randomly selected for training the models, and 30,966 (30% for validation. The models demonstrated excellent calibration and discrimination (AUC: full model  = 0.888 (95% CI 0.877-0.899, reduced model AUC = 0.880 (95% CI, 0.868-0.892, p for difference 0.003, NRI = 2.77%, p = 0.007. Procedural anticoagulation and radial access significantly influenced transfusion rates in the intermediate and high risk patients but no clinically relevant impact was noted in low risk patients, who made up 70% of the total cohort. CONCLUSIONS: The risk of transfusion among patients undergoing PCI can be reliably calculated using a novel easy to use computational tool (https://bmc2.org/calculators/transfusion.

    To review evidence of chronic antipsychotic medication and the association with metabolic syndrome in mentally ill patients. This evidence was used to analyse a cohort of patients with severe mental illness and to deduce a correlation between the prevalence of metabolic syndrome and their dose regimens. Twenty-four male patients undergoing Psychiatric rehabilitation underwent a review of current medication and assessment of risk factors for metabolic syndrome. Assessment criteria was based upon National Cholesterol Education Programme expert panel on detection, evaluation and treatment of high blood cholesterol in adults (Adult Treatment Panel III) (NCEP ATP III) criteria, incorporating waist circumference, raised triglycerides, reduced high density lipoprotein, raised blood pressure and fasting blood glucose. PubMed, Nature and Science Direct databases have been used to compile the medical and scientific background on metabolic syndrome and antipsychotic medication and the effect on patients particularly on high dose. Out of 24 patients, 10 patients (41.7%) were receiving high dose antipsychotics (HDA) and four were on maximum dosage limits of 100%. 8.3% (2/24) patients were receiving only one first generation antipsychotics (FGA), 37.5% (9/24) patients were receiving only one second generation antipsychotic (SGA), 45.8% patients (11/24) were receiving two or more SGA only, and only one patient was receiving two or more FGA. One patient was receiving a combination of FGA and SGA. PRN ("as needed") therapy was not included in this study as their usage was limited. Clozapine was mostly prescribed in these patients (10/24, 41.6%). Four out of the 24 patients refused blood tests therefore were excluded from the following results. In the patients evaluated, 55% (11/20) had confirmed metabolic syndrome. In these patients with metabolic syndrome, 45.4% (5/11) were on HDA and 27.3% (3/11) were on maximum British National Formulary (BNF) limits of 100% of dosage. Four out

    Cardiac manifestations of Marfan syndrome include aortic root dilation and mitral valve prolapse (MVP). Only scant data exist describing MVP in patients with Marfan syndrome undergoing aortic root replacement. We retrospectively analyzed data from 166 MFS patients with MVP who were enrolled in a prospective multicenter registry of patients who underwent aortic root aneurysm repair. Of these 166 patients, 9% had mitral regurgitation (MR) grade >2, and 10% had MR grade 2. The severity of MVP and MR was evaluated by echocardiography preoperatively and ≤ 3 years postoperatively. Forty-one patients (25%) underwent composite graft aortic valve replacement, and 125 patients (75%) underwent aortic valve-sparing procedures; both groups had similar prevalences of MR grade >2 (P=0.7). Thirty-three patients (20%) underwent concomitant mitral valve (MV) intervention (repair, n=29; replacement, n=4), including all 15 patients with MR grade >2. Only 1 patient required MV reintervention during follow-up (mean clinical follow-up, 31 ± 10 months). Echocardiography performed 21 ± 13 months postoperatively revealed MR >2 in only 3 patients (2%). One early death and 2 late deaths occurred. Although the majority of patients with Marfan syndrome who undergo elective aortic root replacement have MVP, only 20% have concomitant MV procedures. These concomitant procedures do not seem to increase operative risk. In patients with MR grade ≤ 2 who do not undergo a concomitant MV procedure, the short-term incidence of progressive MR is low; however, more follow-up is needed to determine whether patients with MVP and MR grade ≤ 2 would benefit from prophylactic MV intervention.

    Microsurgery for lumbar disc herniation that requires surgical intervention has been well described. The methods vary from traditional open discectomy to minimally invasive techniques. All need adequate preanesthetic preparation of patients as general anesthesia is required for the procedure, and nerve monitoring is necessary to prevent iatrogenic nerve injury. Conventional surgical techniques sometimes require the removal of the corresponding lamina to assess the nerve root and herniated disc, and this may increase the risk for posterior instability of the vertebral body. Should this occur, fusion surgery may be needed, further increasing morbidity and cost. We present here a case of lumbar herniated disc fragments causing acute cauda equina syndrome that were endoscopically resected through a transforaminal approach in an awake patient under local anesthesia. Percutaneous endoscopic discectomy under local anesthesia proved to be a better alternative to open back surgery as it made immediate intervention possible, was associated with fewer perioperative complications and morbidity, minimized soft tissue damage, and allowed early rehabilitation with a better outcome and greater patient satisfaction. In addition to these advantages, percutaneous endoscopic discectomy protects other approaches that may be needed in subsequent surgeries, whether open or minimally invasive.

    Background Exposure to traffic-related air pollution (TRAP) is considered to have a carcinogenic effect. The authors previously reported a nonsignificant association between TRAP and cancer risk in a relatively small cohort of myocardial infarction survivors. This study assessed whether TRAP exposure is associated with subsequent cancer in a large cohort of coronary patients. Methods & results Consecutive patients undergoing percutaneous coronary interventions in a major medical centre in central Israel from 2004 to 2014 were followed for cancer through 2015. Residential levels of nitrogen oxides (NO x ) - a proxy for TRAP - were estimated based on a high-resolution national land use regression model. Cox proportional hazards models were constructed to study relationships with cancer. Among 12,784 candidate patients, 9816 had available exposure data and no history of cancer (mean age, 68 years; 77% men). During a median (25th-75th percentiles) follow-up of 7.0 (3.9-9.3) years, 773 incident cases of cancer (8%) were diagnosed. In a multivariable-adjusted model, a 10-ppb increase in mean NO x exposure was associated with hazard ratios (HRs) of 1.07 (95% confidence interval [CI] 1.00-1.15) for all-site cancer and 1.16 (95% CI 1.05-1.28) for cancers previously linked to TRAP (lung, breast, prostate, kidney and bladder). A stronger association was observed for breast cancer (HR = 1.43; 95% CI 1.12-1.83). Associations were slightly strengthened after limiting the cohort to patients with more precise exposure assessment. Conclusion Coronary patients exposed to TRAP are at increased risk of several types of cancer, particularly lung, prostate and breast. As these cancers are amenable to prevention strategies, identifying highly exposed patients may provide an opportunity to improve clinical care.

    Several studies have demonstrated that primary percutaneous coronary intervention (PCI) can result in reperfusion injury. This study aims to investigate the effectiveness of liposomal prostaglandin E1 (Lipo-PGE1, Alprostadil, Beijing Tide Pharmaceutical Co., Ltd.) for enhancing microcirculation in reperfusion injury. In addition, this study determined the optimal administration method for acute ST elevation myocardial infarction (STEMI) patients undergoing primary PCI. Totally, 68 patients with STEMI were randomly assigned to two groups: intravenous administration of Lipo-PGE1 (Group A), and no Lipo-PGE1 administration (Group B). The corrected thrombolysis in myocardial infarction (TIMI) frame count (cTFC) and myocardial blush grade (MBG) were calculated. Patients were followed up for 6 months. Major adverse cardiac events (MACE) were also measured. There was no significant difference in the baseline characteristics between the two groups. The cTFC parameter in Group A was significantly lower than Group B (18.06 ± 2.06 vs. 25.31 ± 2.59, P < 0.01). The ratio of final MBG grade-3 was significantly higher (P < 0.05) in Group A (87.9%) relative to Group B (65.7%). There was no significant difference between the two groups in final TIMI-3 flow and no-reflow. Patients were followed up for 6 months, and the occurrence of MACE in Group A was significantly lower than that in Group B (6.1% vs. 25.9% respectively, P < 0.05). Myocardial microcirculation of reperfusion injury in patients with STEMI, after primary PCI, can be improved by administering Lipo-PGE1.

    Full Text Available Serum alkaline phosphatase (ALP has been shown to be a prognostic factor in several subgroups of patients due to its promotion of vascular calcification. However, the prognostic impact of serum ALP level in ST-segment elevation myocardial infarction (STEMI patients with a relatively low calcification burden has not been determined. We aimed to investigate the association of ALP level measured at time of presentation on clinical outcomes in patients with STEMI requiring primary percutaneous coronary intervention (PCI.A total of 1178 patients with STEMI undergoing primary PCI between 2007 and 2014 were retrospectively enrolled from the INTERSTELLAR registry and classified into tertiles by ALP level (83 IU/L. The primary study outcome was a major adverse cardiac or cerebrovascular event (MACCE, defined as the composite of all-cause death, non-fatal myocardial infarction, non-fatal stroke, and ischemia-driven revascularization.Median follow-up duration was 25 months (interquartile range, 10-39 months. The incidence of MACCE significantly increased as ALP level increased, that is, for the 83 IU/L tertiles incidences were 8.7%, 11.7%, and 15.7%, respectively; p for trend = 0.003. After adjustment for potential confounders, the adjusted hazard ratios for MACCE in the middle and highest tertiles were 1.69 (95% CI 1.01-2.81 and 2.46 (95% CI 1.48-4.09, respectively, as compared with the lowest ALP tertile.Elevated ALP level at presentation, but within the higher limit of normal, was found to be independently associated with higher risk of MACCE after primary PCI in patients with STEMI.

    Objective: To assess the safety and efficacy everolimus-eluting stents (EES) compared with first-generation drug-eluting stents (DES) in patients with acute myocardial infarction (MI) undergoing primary percutaneous coronary intervention (PCI). Background: EES have been associated with improved clinical outcomes compared to paclitaxel-eluting stents (PES) and with similar outcomes compared to sirolimus-eluting stents (SES). Methods: A total of 520 patients who presented with ST-elevation myocardial infarction (STEMI) from 2003 to 2013, who underwent primary PCI with DES, were retrospectively analyzed. Of these, 247 received SES, 136 PES, and 137 EES. Patients were followed up to 2 years for major adverse cardiac events (MACE). Univariate and multivariate models detected correlates to outcome. Results: EES implantation, compared with PES and SES, resulted in comparable rates of MACE (8.8% vs. 16.2%, p = 0.06 and 8.8% vs. 12.6%, respectively, p = 0.26), stent thrombosis, MI, and target lesion revascularization. Patients who received EES had lower rates of all-cause mortality (3.7% vs. 12.6% vs. 9.4%, p = 0.03) at 1-year follow up. However, in the univariate and multivariate analyses, stent type was not independently associated with the primary outcome or with all-cause mortality. Diabetes mellitus and number of stents implanted were independently associated with the primary outcome. Conclusion: While EES seem to be associated with better outcome when compared to PES, the main correlates of STEMI patients are the presence of diabetes and number of stents implanted, and not the type of stent used for intervention.

    Myocardial revascularization by either coronary artery bypass graft surgery (CABG) or percutaneous coronary intervention (PCI) carries the risk of serious complications. Observational data suggest that outcomes may be improved by experienced operators, but there are few studies that have analysed the relationship between mortality and primary operator grade. The aim of this study was to investigate the effect of operator grade (trainee vs. consultant) upon outcomes of revascularization procedures. This was an observational study at a tertiary cardiology centre with accredited training programmes, between 2003 and 2011. A total of 22 697 consecutive patients undergoing either CABG or PCI were included. Associations between operator grade and mortality were assessed by hazard ratios, estimated by Cox regression analyses; 6689 patients underwent CABG, whereas 16 008 underwent PCI. Trainees performed 1968 (29.4%) CABG procedures and 8502 (53.1%) PCI procedures. The proportion of procedures performed by trainees declined over time for both CABG (30.2% in 2003 vs. 26.0% in 2010) and for PCI (58.1% in 2003 vs. 44.5% in 2010). In the unadjusted Cox analysis, consultant operator grade was associated with an increased 5-year mortality after both CABG [HR: 1.26 (95% CI: 1.07-1.47)] and PCI procedures [HR: 1.34 (95% CI: 1.22-1.47)] compared with a trainee operator. However, following multiple adjustment, consultant grade was no longer associated with mortality after either procedure [CABG: HR: 1.02 (95% CI: 0.87-1.20), PCI: HR: 1.08 (95% CI: 0.98-1.20)]. There was no observed detrimental effect on patient outcomes arising from procedures undertaken by trainees working in a structured training environment compared with consultants.

    Red cell distribution width (RDW) is a measure of variation in the size of circulating red blood cells. Recent studies have reported a strong independent relation between elevated RDW and short- and long-term prognosis in various disorders. The aim of the present study was to investigate the relationship between admission RDW-to-platelet ratio (RPR) and in-hospital and long-term prognosis in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). A total of 470 consecutive patients with a diagnosis of STEMI who underwent primary PCI were included in this prospective study. The patients were divided into two groups based on their admission RPR: high (>0.061) RPR group and low (≤0.061) RPR group. The patients were followed for adverse clinical outcomes in-hospital and for up to one year after discharge. In-hospital cardiovascular mortality, major adverse cardiovascular events (MACE), advanced heart failure and cardiogenic shock were significantly higher in the high RPR group (p<0.05). All-cause and cardiovascular mortality, MACE, fatal reinfarction, advanced heart failure, and rehospitalization for cardiac cause were more frequent in the high RPR group in one-year follow-up (p<0.05). High RPR was found to be a significant independent predictor of one-year cardiovascular mortality in multivariate analysis (p=0.003, OR: 3.106, 95% CI: 1.456-6.623). RPR is an inexpensive and readily available biomarker that provides an additional level of risk stratification beyond that provided by conventional risk parameters in predicting long-term MACE and cardiovascular mortality in STEMI.

  4. Serotonin Syndrome in a Patient on Trazodone and Duloxetine Who Received Fentanyl following a Percutaneous Liver Biopsy

    Full Text Available Serotonin syndrome is a rare but potentially life-threatening adverse drug reaction resulting from the use or overuse of serotonergic medications alone or in combination. Mild symptoms, overlapping features with similar conditions and clinician lack of awareness are the major reasons for an often missed diagnosis. Not surprisingly, this condition is significantly underreported as a potential complication of endoscopy if serotonergic medications are used periprocedurally for sedation and analgesia. Here we report the case of a patient with relapsed chronic hepatitis C on antidepressant medications who developed signs and symptoms of serotonin syndrome after a percutaneous liver biopsy. Review of the patient's medication list suggested a possible interaction between her home antidepressants and the post-procedure use of fentanyl for abdominal pain. The patient required monitoring in the medical intensive care unit and stabilized after the administration of benzodiazepines and temporary discontinuation of her home medications. We propose that clinicians need to be aware of the increased risk of serotonin syndrome in the outpatient endoscopy setting, particularly with the wider use of serotonergic antidepressants now available and the repeated number of liver biopsies being performed for management of patients with chronic liver disease.

    Full Text Available Percutaneous nephrolithotomy (PCNL is a technique commonly used to remove large or multiple kidney stones and stones in the inferior calyx, with the advantages of lower morbidity rates, decrease in post-operative pain with faster recovery. Intra-abdominal irrigation fluid extravasation which leads to abdominal hypertension is a rare complication of PCNL with little reports. Early detection of intra-abdominal extravagation is very important to prevent morbidity and mortality. We present two cases and review the literature.

    Patients undergoing percutaneous coronary intervention (PCI) for unstable coronary syndromes have substantial emotional and spiritual distress that may promote procedural complications. Noetic (nonpharmacologic) therapies may reduce anxiety, pain and distress, enhance the efficacy of pharmacologic agents, or affect short- and long-term procedural outcomes. The Monitoring and Actualization of Noetic Training (MANTRA) pilot study examined the feasibility of applying 4 noetic therapies-stress relaxation, imagery, touch therapy, and prayer-to patients in the setting of acute coronary interventions. Eligible patients had acute coronary syndromes and invasive angiography or PCI. Patients were randomized across 5 treatment groups: the 4 noetic and standard therapies. Questionnaires completed before PCI reflected patients' religious beliefs and anxiety. Index hospitalization end points included post-PCI ischemia, death, myocardial infarction, heart failure, and urgent revascularization. Mortality was followed up for 6 months after hospitalization. Of eligible patients, 88% gave informed consent. Of 150 patients enrolled, 120 were assigned to noetic therapy; 118 (98%) completed their therapeutic assignments. All clinical end points were available for 100% of patients. Results were not statistically significant for any outcomes comparisons. There was a 25% to 30% absolute reduction in adverse periprocedural outcomes in patients treated with any noetic therapy compared with standard therapy. The lowest absolute complication rates were observed in patients assigned to off-site prayer. All mortality by 6-month follow-up was in the noetic therapies group. In patients with questionnaire scores indicating a high level of spiritual belief, a high level of personal spiritual activity, a low level of community-based religious involvement, or a high level of anxiety, noetic therapies appeared to show greater reduction in absolute in-hospital complication rates compared with standard

    Our aim was to report on a survey initiated by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) collecting the opinion of the cardiology community on the invasive management of acute coronary syndrome (ACS), before and after the MATRIX trial presentation at the American College of Cardiology (ACC) 2015 Scientific Sessions. A web-based survey was distributed to all individuals registered on the EuroIntervention mailing list (n=15,200). A total of 572 and 763 physicians responded to the pre- and post-ACC survey, respectively. The radial approach emerged as the preferable access site for ACS patients undergoing invasive management with roughly every other responder interpreting the evidence for mortality benefit as definitive and calling for a guidelines upgrade to class I. The most frequently preferred anticoagulant in ACS patients remains unfractionated heparin (UFH), due to higher costs and greater perceived thrombotic risks associated with bivalirudin. However, more than a quarter of participants declared the use of bivalirudin would increase after MATRIX. The MATRIX trial reinforced the evidence for a causal association between bleeding and mortality and triggered consensus on the superiority of the radial versus femoral approach. The belief that bivalirudin mitigates bleeding risk is common, but UFH still remains the preferred anticoagulant based on lower costs and thrombotic risks.

    Full Text Available Abstract Background During percutaneous coronary intervention (PCI, dislodgement of atherothrombotic material from coronary lesions can result in distal embolization, and may lead to increased major adverse cardiovascular events (MACE and mortality. We sought to systematically review the comparative effectiveness of adjunctive devices to remove thrombi or protect against distal embolization in patients with ST-segment elevation myocardial infarction (STEMI undergoing PCI of native vessels. Methods We conducted a systematic literature search of Medline, the Cochrane Database, and Web of Science (January 1996-March 2011, http://www.clinicaltrials.gov, abstracts from major cardiology meetings, TCTMD, and CardioSource Plus. Two investigators independently screened citations and extracted data from randomized controlled trials (RCTs that compared the use of adjunctive devices plus PCI to PCI alone, evaluated patients with STEMI, enrolled a population with 95% of target lesion(s in native vessels, and reported data on at least one pre-specified outcome. Quality was graded as good, fair or poor and the strength of evidence was rated as high, moderate, low or insufficient. Disagreement was resolved through consensus. Results 37 trials met inclusion criteria. At the maximal duration of follow-up, catheter aspiration devices plus PCI significantly decreased the risk of MACE by 27% compared to PCI alone. Catheter aspiration devices also significantly increased the achievement of ST-segment resolution by 49%, myocardial blush grade of 3 (MBG-3 by 39%, and thrombolysis in myocardial infarction (TIMI 3 flow by 8%, while reducing the risk of distal embolization by 44%, no reflow by 48% and coronary dissection by 70% versus standard PCI alone. In a majority of trials, the use of catheter aspiration devices increased procedural time upon qualitative assessment. Distal filter embolic protection devices significantly increased the risk of target revascularization

    Current guidelines recommend prolonged dual antiplatelet therapy (DAPT) for patients with drug-eluting stents (DES) implantation. Nevertheless, optimal discontinuation of DAPT remains a controversy. We performed a meta-analysis of all randomized controlled trials (RCTs) that evaluate optimal discontinuation of DAPT in patients undergoing percutaneous coronary intervention (PCI) with DES. We searched electronic databases including PubMed, Cochrane Library, EMBASE and ClinicalTrials.gov from database RCTs that reported different modes of discontinuation of DAPT in patients with DES. The primary endpoints were all-cause death, cardiovascular death, myocardial infarction (MI) and probably or definite stent thrombosis (ST). Secondary endpoints were repeat revascularization, stroke, major bleeding and net adverse clinical events (NACE). We included 13 RCTs meeting the criteria with a total of 36,749 patients. No significant difference was observed in all-cause death (RR [95% CI]=0.87 [0.75, 1.01], P=0.07, I 2 =0%), cardiovascular death (RR [95% CI]=0.97 [0.79, 1.19], P=0.76, I 2 =0%), repeat revascularization (RR [95% CI]=1.07 [0.92, 1.25], P=0.36, I 2 =0%), and stroke (RR [95% CI]=1.01 [0.80, 1.28], P=0.94, I 2 =0%). Compared with shorter DAPT, longer DAPT was associated with a significant reduction in MI (RR [95% CI]=1.46 [1.26, 1.69], PDES implantation (RR [95% CI]=2.58 [1.85, 3.58], I 2 =0%) and everolimus-eluting stents (EES, RR [95% CI]=1.54 [1.12, 2.11], I 2 =0%). Conversely, there was no difference in thrombotic events in patients with zotarolimus-eluting stents (ZES, RR [95% CI]=1.17 [0.83, 1.63], I 2 =75%) and biodegradable polymer DES (BP-DES, RR [95% CI]=1.15 [0.74, 1.79]). 1) Compared with shorter DAPT, longer DAPT was associated with a significant reduction in thrombotic events (MI and ST) and a higher rate of major bleeding. 2) By the assessment of the trade-off between thrombotic and hemorrhagic events, shorter DAPT was non-inferior to longer DAPT. 3) The

    To develop a system prognostic of outcome in those undergoing allogeneic hematopoietic cell transplantation (allo HCT) for myelodysplastic syndrome (MDS). We examined 2,133 patients with MDS undergoing HLA-matched (n = 1,728) or -mismatched (n = 405) allo HCT from 2000 to 2012. We used a Cox multivariable model to identify factors prognostic of mortality in a training subset (n = 1,151) of the HLA-matched cohort. A weighted score using these factors was assigned to the remaining patients undergoing HLA-matched allo HCT (validation cohort; n = 577) as well as to patients undergoing HLA-mismatched allo HCT. Blood blasts greater than 3% (hazard ratio [HR], 1.41; 95% CI, 1.08 to 1.85), platelets 50 × 10(9)/L or less at transplantation (HR, 1.37; 95% CI, 1.18 to 1.61), Karnofsky performance status less than 90% (HR, 1.25; 95% CI, 1.06 to 1.28), comprehensive cytogenetic risk score of poor or very poor (HR, 1.43; 95% CI, 1.14 to 1.80), and age 30 to 49 years (HR, 1.60; 95% CI, 1.09 to 2.35) were associated with increased hazard of death and assigned 1 point in the scoring system. Monosomal karyotype (HR, 2.01; 95% CI, 1.65 to 2.45) and age 50 years or older (HR, 1.93; 95% CI, 1.36 to 2.83) were assigned 2 points. The 3-year overall survival after transplantation in patients with low (0 to 1 points), intermediate (2 to 3), high (4 to 5) and very high (≥ 6) scores was 71% (95% CI, 58% to 85%), 49% (95% CI, 42% to 56%), 41% (95% CI, 31% to 51%), and 25% (95% CI, 4% to 46%), respectively (P < .001). Increasing score was predictive of increased relapse (P < .001) and treatment-related mortality (P < .001) in the HLA-matched set and relapse (P < .001) in the HLA-mismatched cohort. The proposed system is prognostic of outcome in patients undergoing HLA-matched and -mismatched allo HCT for MDS. © 2016 by American Society of Clinical Oncology.

    Several concerns have emerged regarding the higher risk for stent thrombosis (ST) after drug-eluting stent (DES) implantation, especially in the setting of ST-segment elevation myocardial infarction (STEMI). Few data have been reported so far in patients with diabetes mellitus, which is associated...... with BMS in patients with diabetes who undergo primary percutaneous coronary intervention for STEMI. Published reports were scanned by formal searches of electronic databases (MEDLINE and CENTRAL). All completed randomized trials of DES for STEMI were examined.

    The efficacy of a single oral dose of 0.3M of sodium citrate alone as a prophylaxis against acid aspiration syndrome in obstetric patients undergoing LSCS (elective and emergency) was compared with that of intravenous ranitidine. One group of patients was given 30 ml of 0.3M sodium citrate orally just before the induction of anaesthesia while the other group was given 50mg of ranitidine intravenously together with the 30ml of 0.3M sodium citrate. This was done for both the elective and the emergency groups of patients. There was no significant difference in the mean pH of the gastric aspirate obtained from those given sodium citrate alone and those given sodium citrate and ranitidine in either the elective or the emergency group. However, in the emergency group, those who were given sodium citrate alone tend to have a larger volume of gastric aspiration when compared with those given ranitidine together with the sodium citrate. There were significantly more patients with gastric aspirates of more than 25ml in the emergency group to which sodium citrate alone was given. It would appear that supplementing an intravenous dose of ranitidine with the oral dose of sodium citrate is useful in emergency LSCS as a prophylaxis against acid aspiration syndrome.

    To prospectively evaluate the incidence of post-ablation syndrome (fever and flu-like symptoms) and impact on the quality of life in the first 10 days following percutaneous image-guided cryoablation for renal cell carcinoma (RCC). A prospective study of all cryoablation procedures with biopsy proven RCC was conducted with institutional review board approval between 08/2012 and 04/2016. Sixty-four patients (43 males and 21 females) underwent cryoablation. Mean age was 68 (range 24-86). A telephone questionnaire survey was conducted on days 1, 3, 5, 7 and 10 following cryoablation, and complications were recorded. Data collected included temperature, degree of flu-like symptoms, severity of pain, percentage of pain relief with analgesics, interference with general activity and with work (graded on a 0-10 Numeric Intensity Scale). Following cryoablation, six patients (9%) out of 64 developed post-ablation syndrome. Thirty-three patients (52%) developed flu-like symptoms only, which completely resolved by day 10 in 25 patients (39%). One patient had pyrexia only, which was self- limiting by day 10. Twenty-four patients (38%) were asymptomatic. Pain (mean score = 2.1) and interference on general activities (mean score = 1.8) and work (mean score = 2) following cryoablation peaked on day 3 and improved subsequently. Forty-six patients (72%) had 90-100% pain relief by day 10. No major complications were observed. The full spectrum of post-ablation syndrome following cryoablation occurs in approximately 9% of patients; however, 61% of patients experience flu-like symptoms in the first 10 days, which are self-limiting.

    Potent P2Y 12 inhibitors might offer enhanced benefit against thrombotic events in complex percutaneous coronary intervention (PCI). We examined prasugrel use and outcomes according to PCI complexity, as well as analyzing treatment effects according to thienopyridine type. PROMETHEUS was a multicentre observational study that compared clopidogrel vs prasugrel in acute coronary syndrome patients who underwent PCI (n = 19,914). Complex PCI was defined as PCI of the left main, bifurcation lesion, moderate-severely calcified lesion, or total stent length ≥ 30 mm. Major adverse cardiac events (MACE) were a composite of death, myocardial infarction, stroke, or unplanned revascularization. Outcomes were adjusted using multivariable Cox regression for effect of PCI complexity and propensity-stratified analysis for effect of thienopyridine type. The study cohort included 48.9% (n = 9735) complex and 51.1% (n = 10,179) noncomplex patients. Second generation drug-eluting stents were used in 70.1% complex and 66.2% noncomplex PCI patients (P < 0.0001). Complex PCI was associated with greater adjusted risk of 1-year MACE (hazard ratio [HR], 1.29; 95% confidence interval [CI], 1.20-1.39; P < 0.001). Prasugrel was prescribed in 20.7% of complex and 20.1% of noncomplex PCI patients (P = 0.30). Compared with clopidogrel, prasugrel significantly decreased adjusted risk for 1-year MACE in complex PCI (HR, 0.79; 95% CI, 0.68-0.92) but not noncomplex PCI (HR, 0.91; 95% CI, 0.77-1.08), albeit there was no evidence of interaction (P interaction = 0.281). Despite the use of contemporary techniques, acute coronary syndrome patients who undergo complex PCI had significantly higher rates of 1-year MACE. Adjusted magnitude of treatment effects with prasugrel vs clopidogrel were consistent in complex and noncomplex PCI without evidence of interaction. Copyright © 2018. Published by Elsevier Inc.

    Identifying reperfusion and predicting post procedure risk is important following Percutaneous Coronary Interventions (PCI). An Angiographic Perfusion Score (APS) combining TIMI flow (TFG) and myocardial perfusion (TMPG) grades before and after PCI can accurately measure both epicardial and myocardial perfusion and predict Major Adverse Cardiac Events (MACE). APS was calculated in 226 (88 ST elevation Myocardial Infarction (STEMI) and 138 Non STEMI) patients. Maximum score being 12, reperfusion was defined as failed: 0-3, partial: 4-9, and full APS: 10-12. Thirty day MACE were observed. APS identified reperfusion significantly more than TMPG alone (STEMI: 50.6% vs 11.8% (p APS group (1.8% vs 22.5%) (p APS detects more low risk reperfused patients, post PCI. Copyright © 2012.

    This study compared the performance of Celt ACD ® , a novel stainless steel based vascular closure device versus manual compression (MC) for femoral arteriotomy site hemostasis in patients undergoing percutaneous coronary procedures. Optimal access site management after percutaneous transfemoral procedures remains controversial. Patients enrolled in this multicenter, randomized open label trial underwent 6-F diagnostic or interventional procedures and were assigned 2:1 to Celt ACD ® versus MC. All patients were on full anticoagulation. The primary efficacy end point was time to hemostasis (TTH) and the primary safety end points were 30-day incidence of major procedural and access site related complications. The trial allocated 207 patients to Celt ACD ® (n = 148) versus MC (n = 59) at 5 investigational sites. Baseline characteristics of the two groups were similar. Median TTH was 0 (Interquartile range (IQR): 0, 0.33) in the Celt ACD ® compared to 8 min (IQR: 0, 20; P ACD ® versus 98.1% in the MC group (P = NS). There was a single major adverse event due to device maldeployment and embolization with successful percutaneous retrieval. The 30-day major complication rate was 0.7% in the Celt ACD ® and 0% in the MC group (P = NS). After 6-F percutaneous invasive procedures in fully anticoagulated patients, TTH was significantly reduced in patients assigned to Celt ACD ® compared to patients managed with MC. The 30-day rates of vascular complications were similarly low in both groups. (CELT ACD Trial; NCT01600482) © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Full Text Available Background and Objectives: Patients with chronic kidney disease (CKD are more prone for bleeding following percutaneous renal intervention, as compared to those with normal renal function. Causes are multi-factorial. Finding multiple aneurysms away from the site of renal intervention following initial angioembolization for hemorrhage is very unusual in these patients. Materials and Methods: Clinical and radiological findings of all the patients who underwent renal angiography for post-intervention bleed for a period of 5 years were reviewed and analyzed. Results: A total of 29 patients required angiography for post-intervention hemorrhage. Six patients had recurrence of hemorrhage for which they underwent repeat angiography. Four of these patients had appearance of multiple new aneurysms away from the site of percutaneous nephrostomy (PCN/percutaneous nephrolithotomy (PNL puncture and the site of previous bleeding. All the patients had CKD (creatinine >2.5 mg/dl. They were on prolonged preoperative urinary diversion and had polymicrobial urinary infection. Three patients had candiduria. None of these patients had re-bleeding after repeat embolization and treatment with antibacterial and antifungal agents. Conclusions: Development of multiple aneurysms away from the sites of punctures in patients with CKD following percutaneous intervention is very unusual. Its causation including infection with bacteria and fungus, reaction of embolizing material, and angiopathy needs to be explored.

    Pierre-Robin syndrome (PRS) is often associated with difficulty in endotracheal intubation. We present the use of percutaneous dilational tracheotomy (PDT) for airway management of a newborn with PRS and a glossopharyngeal web. A 2-day-old term newborn with PRS and severe obstructive dyspnea was evaluated by the anesthesiology team for airway management. A direct laryngoscopy revealed a glossopharyngeal web extending from the base of the tongue to the posterior pharyngeal wall. The infant was spontaneously breathing through a 2 mm diameter fistula in the center of this web. It was decided that endotracheal intubation was impossible, and a PDT was planned. The trachea of the newborn was cannulated, using a 20 gauge peripheral venous catheter and a 0.71 mm guide wire was introduced through this catheter. Using 5 French, 7 French, 9 French, and 11 French central venous catheter kit dilators, staged tracheotomy stoma dilation was performed. By inserting a size 3.0 tracheotomy cannula, PDT was successfully completed in this newborn. This case describes the successful use of PDT for emergency airway management of a newborn with PRS and glossopharyngeal web.

    To evaluate (i) local coronary and systemic levels of microparticles (MP) in acute coronary syndrome (ACS) and stable angina pectoris (SAP) patients and (ii) their release after plaque disruption with percutaneous coronary intervention (PCI). MP are small vesicles originating from plasma membranes of cells after activation or apoptosis and are implicated in the pathogenesis of atherosclerosis. Neutrophils play a role in plaque destabilization and shed neutrophil-derived MP that have the potential to drive significant proinflammatory and thrombotic downstream effects. Eight ACS and eight SAP patients were included. Coronary sinus (CS) samples pre-intervention (CS1), 45 s following balloon angioplasty (CS2) and at 45 s intervals following stent deployment (CS3, CS4 and CS5), together with peripheral vein samples, pre- and post-PCI were analysed for neutrophil-derived (CD66b+), endothelial-derived (CD144+), platelet-derived (CD41a+), monocyte-derived (CD14+) and apoptotic (Annexin V+) MP. ELISA for interleukin (IL)-6, myeloperoxidase (MPO) and P-selectin was also performed. CD66b+ MP levels were similar in both groups pre-intervention. Post-PCI, CS levels rose significantly in ACS but not SAP patients (ACS area under the curve (AUC): 549 ± 83, SAP AUC: 24 ± 29, Pderived MP release post-PCI occurs in ACS compared with stable patients, likely to be reflective of plaque MP content in vulnerable lesions. © 2017 The Author(s).

    Full Text Available Background: Acute Coronary Syndrome (ACS is a shift manifestations pattern of ischemic myocardium. Revascularization either with Primary Percutaneous Coronary Intervention (PCI or pharmacological therapy is an optional treatment for ST Elevation Acute Coronary Syndrome (STEACS patients. The aim of the study was to compare the functional capacity using six-minute walking test on STEACS patients who underwent Primary PCI or pharmacological therapy. Methods: A cross sectional study was conducted from September to October 2012 to 35 STEACS patients who were treated after two years. The samples were obtained from the list of patients at Dr. Hasan Sadikin General Hospital. Inclusion criteria consisted of patients diagnosed as STEACS, cooperative and not experiencing cognitive disturbance. The exclusion criteria were STEACS patients with unstable angina or myocardial infarct in the last month, stable exertional angina, and pregnant women. The patients underwent 6 minutes walking test,VO2max was measured using theCalahin and Cooper formula, then Metabolic Equation Task (METs was calculated. Data were analyzed by unpaired T-test. Results: There were 19 Primary PCI and 16 pharmacological therapy patients. The average of age between the two groups was distributed evenly. Most of the STEACS patients were male, had a college/academic degree and were retired. Patients treated with pharmacological therapy had higher average of VO2 max and METs than patients with Primary PCI. There was no significantly differences of METs between those groups (p>0.05 Conclusions: There were no significantly differences of functional capacity in STEACS patients treated with Primary PCI or Pharmacological therapy.

  5. Acute Respiratory Distress Syndrome after Early Successful Primary Percutaneous Coronary Intervention Therapy in Acute Myocardial Infarction: A Case Report

    2005-02-01

    Full Text Available Acute respiratory distress syndrome (ARDS is characterized by acute-onset dyspnea, diffuse bilateral pulmonary infiltration, low pulmonary capillary wedge pressure (PCWP, and an arterial oxygen tension/ inspired oxygen fraction (PaO2/FiO2 ratio of less than 200 mmHg. Acute myocardial infarction (AMI, whether complicated by circulatory arrest, cardiogenic shock, and hypotension or not, was reported as an etiologic factor in the development of ARDS in the prethrombolytic era. In the thrombolytic era, two cases of AMI complicated with ARDS have been reported. ARDS in these two patients resulted from anaphylactic reaction to the thrombolytic agent and not from the hemodynamic consequences of AMI. Development of ARDS during the AMI period has not been reported after early successful primary percutaneous coronary intervention (PCI. Herein, we report a 61-year-old male patient with persistent chest pain who was diagnosed with Killip II anterior ST-segment elevation AMI. He was treated successfully with primary PCI 2.5 hours after the onset of chest pain. Unfortunately, on the third hospital day, acuteonset dyspnea (respiratory rate, 33 beats/min, fever (38.5°C, leukocytosis (white blood cell count, 18,360/μL, and diffuse bilateral pulmonary infiltration were noted. ARDS was diagnosed from the low PCWP (8 mmHg and a PaO2/FiO2 of less than 200 mmHg (160 mmHg. No usual causes of ARDS such as infection, aspiration, trauma, shock, or drug reactions were noted. We assumed that, in this particular patient, the systemic inflammatory response syndrome frequently induced by AMI might have caused this episode of ARDS. This may imply that AMI itself is a possible etiology of ARDS.

    The aim of this study was to explore whether intravenous administration of liposomal prostaglandin E1 (lipo-PGE1) can reduce the incidence of periprocedural myocardial injury (PMI) in patients with unstable angina undergoing an elective percutaneous coronary intervention (PCI). In this randomized-controlled study, a total of 219 patients were randomly assigned to a lipo-PGE1 group (n=110) and a control group (n=109). Patients in the lipo-PGE1 group received 20 μg/day of lipo-PGE1 diluted in 10 ml of normal saline through an intravenous injection over 5 min starting at 3 days before PCI and continuing for 4 days after PCI. In the control group, 10 ml of normal saline was administered using the same method. The primary end point was the occurrence of PMI defined as an elevation of cardiac troponin I above the upper limit of normal within 24 h after the procedure. The secondary end points were (i) changes in inflammatory factors including plasma high-sensitivity C-reactive protein, tumor necrosis factor α, and interleukin 6 before and at 24 h after PCI; (ii) the incidence of major adverse cardiac events in the patients during hospitalization and 30 days of follow-up after discharge, including cardiac deaths, severe heart failure, malignant arrhythmias, and target vessel revascularization. Within 24 h after PCI, the incidence of PMI was significantly lower in the lipo-PGE1 group compared with that in the control group (20 vs. 36.69%, P=0.009). Although the procedure induced a significant increase in high-sensitivity C-reactive protein, tumor necrosis factor α, and interleukin 6 levels, the values were significantly lower in the lipo-PGE1 group than those in the control group at 24 h after PCI (P<0.05). The proportion of thrombolysis in myocardial infarction grade 3 in the lipo-PGE1 group was higher than that in the control group (92.72 vs. 82.56%, P=0.037). There were no significant differences between the lipo-PGE1 group and the control group in the

  7. Heterochromatic genes undergo epigenetic changes and escape silencing in immunodeficiency, centromeric instability, facial anomalies (ICF syndrome.

    Directory of Open Access Journals (Sweden)

    Marie-Elisabeth Brun

    Full Text Available Immunodeficiency, Centromeric Instability, Facial Anomalies (ICF syndrome is a rare autosomal recessive disorder that is characterized by a marked immunodeficiency, severe hypomethylation of the classical satellites 2 and 3 associated with disruption of constitutive heterochromatin, and facial anomalies. Sixty percent of ICF patients have mutations in the DNMT3B (DNA methyltransferase 3B gene, encoding a de novo DNA methyltransferase. In the present study, we have shown that, in ICF lymphoblasts and peripheral blood, juxtacentromeric heterochromatic genes undergo dramatic changes in DNA methylation, indicating that they are bona fide targets of the DNMT3B protein. DNA methylation in heterochromatic genes dropped from about 80% in normal cells to approximately 30% in ICF cells. Hypomethylation was observed in five ICF patients and was associated with activation of these silent genes. Although DNA hypomethylation occurred in all the analyzed heterochromatic genes and in all the ICF patients, gene expression was restricted to some genes, every patient having his own group of activated genes. Histone modifications were preserved in ICF patients. Heterochromatic genes were associated with histone modifications that are typical of inactive chromatin: they had low acetylation on H3 and H4 histones and were slightly enriched in H3K9Me(3, both in ICF and controls. This was also the case for those heterochromatic genes that escaped silencing. This finding suggests that gene activation was not generalized to all the cells, but rather was restricted to a clonal cell population that may contribute to the phenotypic variability observed in ICF syndrome. A slight increase in H3K27 monomethylation was observed both in heterochromatin and active euchromatin in ICF patients; however, no correlation between this modification and activation of heterochromatic genes was found.

Sixty percent of ICF patients have mutations in the DNMT3B (DNA methyltransferase 3B) gene, encoding a de novo DNA methyltransferase. In the present study, we have shown that, in ICF lymphoblasts and peripheral blood, juxtacentromeric heterochromatic genes undergo dramatic changes in DNA methylation, indicating that they are bona fide targets of the DNMT3B protein. DNA methylation in heterochromatic genes dropped from about 80% in normal cells to approximately 30% in ICF cells. Hypomethylation was observed in five ICF patients and was associated with activation of these silent genes. Although DNA hypomethylation occurred in all the analyzed heterochromatic genes and in all the ICF patients, gene expression was restricted to some genes, every patient having his own group of activated genes. Histone modifications were preserved in ICF patients. Heterochromatic genes were associated with histone modifications that are typical of inactive chromatin: they had low acetylation on H3 and H4 histones and were slightly enriched in H3K9Me3, both in ICF and controls. This was also the case for those heterochromatic genes that escaped silencing. This finding suggests that gene activation was not generalized to all the cells, but rather was restricted to a clonal cell population that may contribute to the phenotypic variability observed in ICF syndrome. A slight increase in H3K27 monomethylation was observed both in heterochromatin and active euchromatin in ICF patients; however, no correlation between this modification and activation of heterochromatic genes was found.

    A 31-year-old woman with Cogan syndrome (a rare form of systemic vasculitis) was evaluated for a cold, painful left foot with diminished pulses. Arteriography demonstrated thrombosis of the left popliteal artery with evidence of vasculitis. Thrombolytic therapy was begun with initial success but eventual rethrombosis. After reinitiating thrombolytic therapy combined with intraarterial vasodilator therapy, successful angioplasty was performed with sustained results, at 6-month follow-up

    Introduction: Myofascial pain syndrome (MPS) treatment is challenging with a high recurrence rate and still lacks a clear treatment frame. Therefore research on new, more efficient and long lasting effect treatment modalities is necessary. This study looked at the effects of intravenous laser therapy (IVL) and percutaneous low level laser (PLLL) in the management of shoulder MPS. Methods: In this randomized controlled trial, 30 patients fulfilling inclusion criteria were randomly equally allocated to 3 groups, control, IVL and PLLL. Control group received 12 sessions of placebo low level laser, IVL group received 12 sessions of IVL therapy, and PLLL group received 12 sessions of PLLL therapy. All patients were trained for better body posture, body mechanics, gentle massage of trigger points, stretching exercises of affected muscle (trapezius), and received 10 mg of oral nortriptyline regimen every night for 3 months. Outcomes included pain severity, functional disability, and quality of life. Patients were assessed using Numeric Rating Scale (NRS), Pain Disability Index (PDI), and Short Form Health Survey (SF-12). Data collected were analyzed using analysis of variance (ANOVA), Mann-Whitney and t tests. Results: The mean of PDI and maximum pain intensity during day and night significantly reduced in both PLLL and IVL groups compared to control group. Although pain severity and PDI reduction was more pronounced in IVL group compared to PLLL group, the differences were not statistically significant. Also, quality of life statistically significantly improved in both IVL and PLLL groups compared to control group was more, and although higher in IVL group, the difference was not statistically significant when compared to PLLL group. No side effects were observed in the intervention groups. Conclusion: Intravenous laser and PLLL therapy had a positive effect on pain severity and PDI reduction, and quality of life in this study. Also no adverse event was recorded. Thus

    Less than 2.7% of infants undergoing congenital heart disease operations have difficulty weaning from invasive mechanical ventilation. In such instances, clinicians may choose to perform tracheostomy. Limited literature has examined tracheostomy placement specifically in infants with hypoplastic left heart syndrome (HLHS). This study evaluated the risk factors for tracheostomy placement in infants with HLHS and examined the outcomes of these infants before their first hospital discharge. This retrospective analysis of the Pediatric Heath Information System data set included infants with HLHS who underwent stage 1 Norwood operation, a hybrid procedure, or heart transplant from 2004 through 2013. We identified 5721 infants with HLHS, and 126 underwent tracheostomy placement. Infants in the tracheostomy group had more morbidities and a higher mortality rate across the study period. Diagnosis of chromosomal abnormalities, anomalies of the trachea and esophagus, larynx, diaphragm and nervous system, bilateral vocal cord paralysis, and necrotizing enterocolitis, and procedures including extracorporeal membrane oxygenation support, cardiac catheterization, and gastrostomy tube were independently associated with tracheostomy placement in the study population. Despite an overall increase in rates of tracheostomy performed in infants with HLHS during the study period, the mortality rate did not improve among tracheostomy patients. Several risk factors were identified in infants with HLHS in whom a tracheostomy was placed during their first hospitalization. Despite an overall increase in rates of tracheostomies during the study period, the mortality rate did not improve among these patients. Appropriate family counseling and thorough preoperative case selection is suggested when discussing possible tracheostomy placement in infants with HLHS.

    The study aim was to investigate the long-term prognosis and risk factors of postpericardiotomy syndrome (PPS). We performed a single-center cohort study in 822 patients undergoing nonemergent valve surgery. Risk factors of PPS were evaluated using multivariable logistic regression analysis. We also compared the incidence of reoperation for tamponade at 1 year between patients with and without PPS. Main secondary outcomes were hospital stay and mortality. Of the 822 patients, 119 (14.5%) developed PPS. A higher body mass index (odds ratio (OR) per point increase, 0.94; 95% confidence interval (CI), 0.89-0.99) was associated with a lower risk of PPS, whereas preoperative treatment for pulmonary disease without corticosteroids (OR, 2.55; 95% CI, 1.25-5.20) was associated with a higher risk of PPS. The incidence of reoperation for tamponade at 1 year in PPS versus no PPS was 20.9% versus 2.5% (OR, 15.49; 95% CI, 7.14-33.58). One-year mortality in PPS versus no PPS was 4.2% versus 5.5% (OR, 0.68; 95% CI, 0.22-2.08). Median hospital stay was 13 days (interquartile range, 9-18 days) versus 11 days (interquartile range, 8-15 days) (P = .001), respectively. Despite longer hospital stays and more short-term reoperations for tamponade, patients with PPS had an excellent 1-year prognosis. Copyright © 2016 The American Association for Thoracic Surgery.

    The purpose of the study was to evaluate the feasibility and effectiveness of direct porto-caval shunts in patients with Budd-Chiari syndrome (BCS) in whom there is no access to the hepatic veins during transjugular intrahepatic portosystemic shunt (TIPSS). We included six consecutive patients with fulminant/acute Budd-Chiari syndrome (mean age: 35 years) in whom a conventional TIPSS was not possible due to inaccessible hepatic veins. We performed a direct porto-caval shunt via a transhepatic approach. Patients were followed up by means of clinical examination, laboratory investigations, and Doppler ultrasound. TIPSS implantation from the inferior vena cava (IVC) was successful in all six patients (100%). The median transhepatic shunt length was 9 cm (8-10 cm). No procedure-related complications were observed in our patients. Early shunt occlusion occurred in three out of six patients (50%). In all three of these patients, the stent used to stabilize the shunt ended 1-2 cm before reaching the IVC. All occlusions were successfully recanalized. One of these patients developed recurrent early shunt as well as mesenteric and splenic vein occlusions. She died 7 days after TIPSS placement due to an unmanageable coagulation disorder. The remaining five patients were followed up by planned clinical examination and laboratory investigations (mean follow-up time was 15 months; patient 1 was followed up for 13 months, patient 2 for 14 months, patient 3 for 15 months, and patients 4 and 5 for 16 months) and all displayed a complete and durable resolution of liver failure and ascites without reintervention. In patients with acute liver failure originating from BCS and inaccessible hepatic veins, a direct transhepatic porto-caval shunt can be performed safely and effectively under ultrasound guidance. Future studies in larger patient groups should investigate if the patency of transcaval TIPSS with long transhepatic shunt segments is similar compared to conventional TIPSS via

    Many patients with cancer or other systemic illnesses can experience malnutrition. One way to mitigate malnutrition is by insertion of a percutaneous endoscopic gastrostomy feeding tube (PEG tube). The goal of this retrospective matched cohort study is to evaluate if PEG tube placement improved nutritional status and overall survival (OS) in advanced gastroesophageal (GE) cancer patients who are undergoing anti-neoplastic therapy. GE cancer patients who were treated and evaluated by a nutritionist and had at least 2 nutritionist follow-up visits were identified. Patients with PEG tube were matched to patients that did not undergo PEG placement (non-PEG). Clinical characteristics, GE symptoms reported at nutrition follow-up visits, and OS were recorded. 20 PEG and 18 non-PEG cases met criteria for further analyses. After correction for multiple testing, there were no OS differences between PEG and non-PEG, treatment naive and previously treated. However, PEG esophageal carcinoma has statistically significant inferior OS compared with non-PEG esophageal carcinoma. PEG placement did not significantly reduce the proportion of patients with weight loss between the initial nutrition assessment and 12-week follow-up. In this small study, PEG placement had inferior OS outcome for GE esophageal carcinoma, no improvement in OS for other evaluated groups, and did not reduce weight loss between baseline and 12-week follow-up. Unless there is prospective randomized trial that can show superiority of PEG placement in this population, PEG placement in this group cannot be endorsed.

    This retrospective cohort study evaluated the obstetric outcomes in women with polycystic ovary syndrome (PCOS) and isolated polycystic ovaries (PCO) undergoing in vitro fertilization (IVF) treatment. We studied 104 women with PCOS, 184 with PCO and 576 age-matched controls undergoing the first IVF treatment cycle between 2002 and 2009. Obstetric outcomes and complications including gestational diabetes (GDM), gestational hypertension (GHT), gestational proteinuric hypertension (PET), intrauterine growth restriction (IUGR), gestation at delivery, baby's Apgar scores and admission to the neonatal intensive care unit (NICU) were reviewed. Among the 864 patients undergoing IVF treatment, there were 253 live births in total (25 live births in the PCOS group, 54 in the PCO group and 174 in the control group). The prevalence of obstetric complications (GDM, GHT, PET and IUGR) and the obstetric outcomes (gestation at delivery, birth weight, Apgar scores and NICU admissions) were comparable among the three groups. Adjustments for age and multiple pregnancies were made using multiple logistic regression and we found no statistically significant difference among the three groups. Patients with PCO ± PCOS do not have more adverse obstetric outcomes when compared with non-PCO patients undergoing IVF treatment.

    The metabolic syndrome defined by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) is a predictor of cardiovascular events. However, the significance of metabolic syndrome for cardiovascular events has been not clarified in Japan. The impact of metabolic syndrome and diabetes mellitus on cardiovascular events was investigated, especially in the high risk group after percutaneous coronary intervention. We studied 456 patients (mean age 63±10 years, range 36-88 years) without ischemia on stress thallium-201 single photon emission computed tomography after percutaneous coronary intervention. The diagnosis of metabolic syndrome was made according to the modified NCEP ATP III criteria. Cardiovascular events were examined for mean 3.7±1.8 years (range 2.0-8.7 years). There were 196 patients without diabetes mellitus or metabolic syndrome (Group D-M-), 89 patients without diabetes mellitus but with metabolic syndrome (Group D-M+), 61 patients with diabetes mellitus but without metabolic syndrome (Group D+M-), and 110 patients with both diabetes mellitus and metabolic syndrome (Group D+M+). The event-free survival curve in Group D-M+ was significantly lower than that in Group D-M- (p<0.05), but not different from that in Group D+M-. The survival curve was markedly lower in Group D+M+ than that in Group D-M+ (p<0.005). The Cox proportional hazard model revealed that diabetes mellitus and metabolic syndrome were independent significant risk factors for events. The diagnosis of metabolic syndrome was helpful for identification of patients with high cardiovascular event rate even in patients after percutaneous coronary intervention. The combination of metabolic syndrome and diabetes mellitus markedly increases the risk for cardiovascular events. (author)

    Approximately 5 to 7% of patients undergoing percutaneous coronary intervention (PCI) for the treatment of coronary artery disease require chronic oral anticoagulation (OAC) on top of aspirin and a P2Y 12 receptor antagonist, mainly due to non-valvular atrial fibrillation (AF). The advent of non-vitamin K antagonist oral anticoagulants (NOACs) increased treatment options, while there is cumulative evidence that dual combination of a NOAC and a P2Y 12 receptor antagonist attenuates risk of bleeding, compared to traditional triple therapy, consisting of a vitamin K antagonist (VKA), aspirin, and a P2Y 12 receptor antagonist, without significantly compromising efficacy. Greek AntiPlatElet Atrial Fibrillation (GRAPE-AF, NCT 03362788) is an observational, nationwide study of non-valvular AF patients undergoing PCI, planning to enroll over 1-year period > 500 participants in 25 tertiary and non-tertiary PCI centers in Greece. Key data to be collected pre-discharge include demographics, detailed past medical history, and antithrombotic and concomitant treatment. Patients will be followed up at 1, 6, and 12 months post hospital discharge. Αt each follow-up visit, data on antithrombotic treatment, ischemic, bleeding, and adverse events will be collected. Study's primary endpoint is clinically significant bleeding (Bleeding Academic Research Consortium, BARC ≥ 2) at 12 months, between VKAs and NOACs-treated patients, analyzed using Cox proportional hazards models, by an intention-to-treat principle. An independent endpoint committee will adjudicate all clinical events. This study aims at providing "real-world" information on current antithrombotic treatment patterns and clinical outcome of patients with non-valvular AF undergoing PCI.

    Recently, malnutrition has been shown to be related to worse clinical outcomes in patients with heart failure. However, the association between nutritional status and clinical outcomes in patients with coronary artery disease (CAD) remains unclear. We investigated the prognostic value of malnutrition assessed by the Controlling Nutritional Status (CONUT; range 0-12, higher = worse, consisting of serum albumin, cholesterol and lymphocytes) score in patients with CAD. The CONUT score was measured on admission in a total of 1987 patients with stable CAD who underwent elective percutaneous coronary intervention (PCI) between 2000 and 2011. Patients were divided into two groups according to their CONUT score (0-1 vs. ≥2). The incidence of major adverse cardiac events (MACE), including all-cause death and non-fatal myocardial infarction, was evaluated. The median CONUT score was 1 (interquartile range 0-2). During the median follow-up of 7.4 years, 342 MACE occurred (17.2%). Kaplan-Meier curves revealed that patients with high CONUT scores had higher rates of MACE (log-rank p Nutritional status assessed by the CONUT score was significantly associated with long-term clinical outcomes in patients with CAD. Pre-PCI assessment of the CONUT score may provide useful prognostic information.

    The aim of this study is to investigate the association between fractional flow reserve (FFR) values and change in coronary physiological indices after elective percutaneous coronary intervention (PCI). Decision making for revascularization when FFR is 0.75-0.80 is controversial. A retrospective analysis was performed of 296 patients with stable angina pectoris who underwent physiological examinations before and after PCI. To investigate the differences of coronary flow improvement between territories with low-FFR (zone FFR (0.75-0.80), serial changes in physiological indices including mean transit time (Tmn), coronary flow reserve (CFR), and index of microcirculatory resistance (IMR) were compared between these two groups. Compared to low-FFR territories, grey-zone FFR territories showed significantly lower prevalence of Tmn shortening, CFR improvement, and decrease in IMR (Tmn shorting, 63.9% vs. 87.0%, P 51.3% vs. 63.3%, P = .040) and lower extent of their absolute changes (Tmn shorting, 0.06 (-0.03 to 0.16) vs. 0.22 (0.07-0.45), P zone FFR. Physiological assessment combining FFR and IMR may help identify patients who may benefit by PCI, particularly those in the grey zone. © 2018 Wiley Periodicals, Inc.

    The study aims to evaluate the long-term clinical and technical efficacy of recently developed percutaneously introducible plate electrodes for spinal cord stimulation. Twenty-one patients diagnosed with failed back surgery syndrome (FBSS) or lumboischialgia were implanted with a small profile plate-type electrode. Patients were followed-up long term and were asked at baseline, after trial, and during each follow-up visit to score their pain on a visual analog scale (VAS) for pain now, worst pain last week, least pain last week, and mean pain last week. Pain location, electrophysiologic parameters, and number of reprogrammings were collected as well. Furthermore, each patient was asked if he/she would redo the procedure post trial and at each of the follow-up visits. A total of 21 patients were prospectively followed up long term. With a mean follow-up of 40.8 months, a significant mean reduction in patient self-reported pain from baseline to postoperative of 75.79% pain reduction was seen at follow-up 1 and 62.52% at follow-up 2. A significant decrease was obtained for, respectively, pain at the present moment, VAS pain worst last week, VAS pain least last week, and VAS pain mean last week in comparison with baseline VAS scores. All patients indicated that they would redo the procedure. Percutaneous implantation of small profile paddle leads in patients with FBSS and lumboischialgia produces favorable results over the long term that are at least comparable with surgical implanted paddle leads. The percutaneous approach also allows nonsurgically trained pain physicians to introduce paddle leads. Indices like if patients would redo the procedure may be more appropriate for analyzing long-term outcomes than the arbitrarily taking 50% reduction in VAS scores. © 2013 International Neuromodulation Society.

    Piriformis muscle syndrome (PMS) is a cause of sciatica, leg or buttock pain and disability. The pain is usually increased by muscular contraction, palpation or prolonged sitting. The aim of our paper was to evaluate the feasibility of CT-guided percutaneous botulinic toxin (BTX) injection for the purpose of PMS treatment. Thirty patients suffering from PMS, suspected with clinical and electrophysiological criteria, after imaging examinations excluding other causes of sciatic pain, resulted positive at the lidocaine test and were treated by intramuscular injection of BTX type A under CT guidance. The follow-up (12 months) was performed with clinical examination in all cases and with MR 3 months after the procedure in 9 patients to evaluate the denervative process entity of the treated muscle. In 26 cases relief of symptoms was obtained after 5-7 days. In 4 patients an insufficient relief of pain justified a second percutaneous treatment which was clinically successful. No complications or side effects were recorded after BTX injection. The MR examination showed a signal intensity change of the treated muscle in 7 patients due to the denervative process of PM, whereas in the remaining 2 cases only an atrophy of the treated muscle was detected. Larger series are necessary to confirm these MRI preliminary results. The CT-guided BTX injection in the PMS is an emergent and feasible technique that obtains an excellent local therapeutic effect without risk of imprecise inoculation. (orig.)

    The purpose of this study was to evaluate the economic impact of the Absorb bioresorbable vascular scaffold compared with the Xience everolimus-eluting stent in patients undergoing percutaneous coronary intervention. The ABSORB III trial (Everolimus-Eluting Bioresorbable Scaffolds for Coronary Artery Disease) demonstrated that the Absorb scaffold was noninferior to the Xience stent with respect to target lesion failure at 1 year. Whether health care costs differ between the Absorb scaffold and the Xience stent is unknown. We performed a prospective health economic study alongside the ABSORB III trial, in which patients undergoing percutaneous coronary intervention for stable or unstable angina were randomized to receive the Absorb scaffold (n = 1,322) or Xience stent (n = 686). Resource use data were collected through 1 year of follow-up. Costs were assessed using resource-based accounting (for procedures), MedPAR data (for other index hospitalization costs), and Medicare reimbursements (for follow-up costs and physician fees). Initial procedural costs were higher with the Absorb scaffold than the Xience stent ($6,316 ± 1,892 vs. $6,103 ± 1,895; p = 0.02), driven mainly by greater balloon catheter use and the higher cost of the scaffold in the Absorb group. Nonetheless, index hospitalization costs ($15,035 ± 2,992 for Absorb vs. $14,903 ± 3,449 for Xience; p = 0.37) and total 1-year costs ($17,848 ± 6,110 for Absorb vs. $17,498 ± 7,411 for Xience; p = 0.29) were similar between the 2 groups. Although initial procedural costs were higher with the Absorb scaffold, there were no differences in total 1-year health care costs between the 2 cohorts. Longer term follow-up is needed to determine whether meaningful cost savings emerge after scaffold resorption.

    We aimed to explore the relationship between brain natriuretic peptide (BNP) levels and right ventricular (RV) function in patients with mitral stenosis (MS), and to investigate the hemodynamic parameters that predict reduction of BNP levels after percutaneous mitral valvuloplasty (PMV). Few studies have evaluated BNP in the context of MS, specifically the impact of the RV stroke work (RVSW) on serum BNP levels has not been defined. Thirty patients with symptomatic rheumatic MS in sinus rhythm who were referred for a PMV were enrolled. Right and left heart pressures were obtained before and after valvuloplasty. RVSW index (RVSWI) was calculated by cardiac catheterization. Basal BNP levels were elevated in MS patients and correlated with several hemodynamic parameters including pulmonary pressure, pulmonary vascular resistance index, cardiac index (CI), and RVSWI. In multivariate analysis, CI and RVSWI were independent predictors of raised basal BNP levels. PMV resulted in a significant decrease in the RVSWI with a concurrent increase in CI (2.4 ± 0.43 to 2.9 ± 0.8 L/min/m(2), P = 0.010). Overall, plasma BNP levels significantly decreased from 124 (63/234) to 73 (48/148) pg/ml postvalvuloplasty. Multivariate analysis revealed that the reduction of left atrial (LA) pressure post-PMV was an independent predictor of change in BNP levels. Elevated baseline BNP level in MS patients was independently associated with CI and RVSWI. Plasma BNP levels were reduced after successful PMV, which was associated with the reduction of the LA pressure. © 2013, Wiley Periodicals, Inc.

    Several clinical trials have shown that antagonists of the glycoprotein IIb/IIIa receptor decreased the incidence of death, nonfatal myocardial infarction, and the need for urgent revascularization when administered immediately before or during the 24- to 48-hour period after percutaneous coronary intervention (PCI). However, these agents increased the risk of thrombocytopenia and periprocedural bleeding complications. Therefore, the relation between periprocedural bleeding complications during PCI and long-term outcome was assessed in 6,995 patients in the EXCITE trial. Periprocedural bleeding was classified as none, mild, moderate, and severe. Measured outcomes included the incidence of all-cause mortality or the composite end point (cardiovascular disease) of death, myocardial infarction, or stroke. Subjects were followed up for a median of 210 days (7 months). Mean patient age was 59.1 years, and 21.8% were women. Periprocedural bleeding complications occurred in 1,869 patients (26.7%), and blood transfusion was administered to 189 patients (2.7%). In multivariate analysis, periprocedural bleeding complications were significantly associated with increased risk of the composite outcome for mild (hazard ratio [HR] 0.80, 95% confidence interval [CI] 0.64 to 0.97), moderate (HR 2.38, 95% CI 1.78 to 3.20), and severe bleeding complications (HR 3.55, 95% CI 2.20 to 5.73) during follow-up. Also, the necessity of blood transfusion was an important predictor of the composite end point (HR 2.61, 95% CI 1.96 to 3.60). Patients in the United States were more likely to be administered a blood transfusion than non-US patients independently of cardiovascular risk factors. In conclusion, moderate and severe periprocedural bleeding complications increased the risk of mortality and incident cardiovascular events after PCI.

    Recent randomized clinical trials demonstrated that transradial approach was a preferred approach for primary percutaneous coronary intervention (PCI) in ST-elevation acute myocardial infarction (STEMI). However, clinical outcomes of transradial approach in STEMI have not been adequately evaluated yet in the real-world practice, which includes hemodynamically unstable high-risk patients. We identified 3662 STEMI patients who had primary PCI within 24 h after symptom onset and were treated by transradial (N = 471) or transfemoral (N = 3191) approach in the CREDO-Kyoto AMI registry. In the current analysis, we compared clinical characteristics and long-term outcomes between the 2 groups of patients treated by transradial approach and transfemoral approach. The prevalence of hemodynamically compromised patients (Killip II-IV) was significantly less in the transradial group than in the transfemoral group (19 vs. 25%, P = 0.002). Cumulative 5-year incidences of death/MI/stroke, and major bleeding were not significantly different between the transradial and transfemoral groups (26.7 vs. 25.9%, log-rank P = 0.91, and 11.3 vs. 11.5%, log-rank P = 0.71, respectively). After adjustment for confounders, the risks of the transradial group relative to the transfemoral group were not significant for both death/MI/stroke [Hazard ratio (HR) 1.15, 95% confidence interval (CI) 0.83-1.59, P = 0.41] and major bleeding (HR 1.29, 95% CI 0.77-2.15, P = 0.34). In the subgroup of hemodynamically compromised patients, there were also no significant differences in the risks for death/MI/stroke and major bleeding between the 2 groups. Clinical outcomes of transradial approach were not different from those of transfemoral approach in primary PCI for STEMI in the real-world practice.

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

    This study compared percutaneous tibial nerve stimulation (PTNS) versus electrical stimulation with pelvic floor muscle training (ES + PFMT) in women with overactive bladder syndrome (OAB). 60 women with OAB were enrolled. Patients were randomized into two groups. In group A, women underwent ES with PFMT, in group B women underwent PTNS. A statistically significant reduction in the number of daily micturitions, episodes of nocturia and urge incontinence was found in the two groups but the difference was more substantial in women treated with PTNS; voided volume increased in both groups. Quality of life improved in both groups, whereas patient perception of urgency improved only in women treated with PTNS. Global impression of improvement revealed a greater satisfaction in patients treated with PTNS. This study demonstrates the effectiveness of PTNS and ES with PFMT in women with OAB, but greater improvements were found with PTNS. Copyright® by the International Brazilian Journal of Urology.

    Metformin is used among patients with polycystic ovary syndrome (PCOS), but findings for its effects on outcomes of assisted reproductive technology (ART) have been conflicting. To compare ART outcomes among women with PCOS who were and were not given metformin. Databases were searched for reports published in English between 2002 and 2013, using combinations of the terms "polycystic ovary syndrome," "PCOS," "insulin-sensitizing," and "metformin." Randomized controlled trials of metformin versus placebo among women with PCOS undergoing ART were included if they assessed rates of pregnancy, live birth, spontaneous abortion, multiple pregnancy, and/or ovarian hyperstimulation syndrome (OHSS). Data were extracted from included studies. The Mantel-Haenzel random-effects model was used for meta-analyses. Twelve studies (1516 participants) were included. No significant differences were recorded between metformin and placebo groups for rates of pregnancy (risk ratio [RR] 1.11, 95% CI 0.92-1.33), live birth (RR 1.12, 0.92-1.36), spontaneous abortion (RR 1.00, 0.60-1.67), or multiple pregnancy (RR 0.96, 0.47-1.96). However, OHSS rate was significantly lower among patients who received metformin than among those who received placebo (RR 0.44, 0.26-0.77). Metformin does not improve ART outcomes among patients with PCOS, but does significantly reduce their risk of OHSS. Copyright © 2015 International Federation of Gynecology and Obstetrics.

    Full Text Available AbstractIntroduction Treacher Collins syndrome, or mandibulofacial dysostosis, is a hereditary disorder and is manifested by craniofacial malformations. The incidence is close to one case per 40,000 live births, without relation to gender or race. The infant carrier may present neurological development. This rare syndrome requires documentation of its main clinical and kinetic-functional consequences.Objectives The purpose of this study was to describe the clinical and kinetic-functional findings for a child who has Treacher Collins syndrome and receives treatment in the Physiotherapy Department at the Pestalozzi Association in Goiania, and to present the evolution of motor function and psychomotor development during rehabilitation.Materials and methods The information was obtained through interviews with the mother, and evaluation of the child at nine and eleven months old, using the infant neurological assessment sheet, Inventory Operational Portage (IPO and Gross Motor Function Measure (GMFM.Results The GMFM showed that the child had a higher trend in the items for lying and rolling, sitting, crawling and kneeling and minor changes in the items for standing, walking, running and jumping. In the IPO, the child progressed in all of the assessed areas: infant stimulation, motor development, socialization, self-care, cognition and language.Conclusion The child showed progress in psychomotor development in accordance with that expected for their age and initial assessment. It is suggested that children with this syndrome be treated by multidisciplinary teams in the first years of life, preventing delays and deviations in development.

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

    This study sought to develop a model that predicts bleeding complications using an expanded bleeding definition among patients undergoing percutaneous coronary intervention (PCI) in contemporary clinical practice. New knowledge about the importance of periprocedural bleeding combined with techniques to mitigate its occurrence and the inclusion of new data in the updated CathPCI Registry data collection forms encouraged us to develop a new bleeding definition and risk model to improve the monitoring and safety of PCI. Detailed clinical data from 1,043,759 PCI procedures at 1,142 centers from February 2008 through April 2011 participating in the CathPCI Registry were used to identify factors associated with major bleeding complications occurring within 72 h post-PCI. Risk models (full and simplified risk scores) were developed in 80% of the cohort and validated in the remaining 20%. Model discrimination and calibration were assessed in the overall population and among the following pre-specified patient subgroups: females, those older than 70 years of age, those with diabetes mellitus, those with ST-segment elevation myocardial infarction, and those who did not undergo in-hospital coronary artery bypass grafting. Using the updated definition, the rate of bleeding was 5.8%. The full model included 31 variables, and the risk score had 10. The full model had similar discriminatory value across pre-specified subgroups and was well calibrated across the PCI risk spectrum. The updated bleeding definition identifies important post-PCI bleeding events. Risk models that use this expanded definition provide accurate estimates of post-PCI bleeding risk, thereby better informing clinical decision making and facilitating risk-adjusted provider feedback to support quality improvement.

    Proteinuria was associated with cardiovascular events and mortality in community-based cohorts. The association of proteinuria with mortality and cardiovascular events in patients undergoing percutaneous coronary intervention (PCI) was unknown. The association of urinary dipstick proteinuria with mortality and cardiovascular events (composite of death, myocardial infarction, or nonhemorrhagic stroke) in 5,835 subjects of the EXCITE trial was evaluated. Dipstick urinalysis was performed before PCI, and proteinuria was defined as trace or greater. Subjects were followed up for 210 days/7 months after enrollment for the occurrence of events. Multivariate Cox regression analysis evaluated the independent association of proteinuria with each outcome. Mean age was 59 years, 21% were women, 18% had diabetes mellitus, and mean estimated glomerular filtration rate was 90 ml/min/1.73 m(2). Proteinuria was present in 750 patients (13%). During follow-up, 22 subjects (2.9%) with proteinuria and 54 subjects (1.1%) without proteinuria died (adjusted hazard ratio 2.83, 95% confidence interval [CI] 1.65 to 4.84, p use tool as urinary dipstick may be useful to identify and treat patients at high risk of mortality at the time of PCI.

    Full Text Available Background. High levels of Pentraxin 3 (PTX3 are reported in acute myocardial infarction (AMI. Aim. To investigate circulating levels and gene expression of PTX3 in patients with AMI and stable angina pectoris (AP undergoing PCI. Methods. Ten patients with AP and 20 patients with AMI were included. Blood samples were drawn before PCI in the AP group and after 3 and 12 hours and days 1, 3, 5, 7, and 14 in both groups. Results. Circulating PTX3 levels were higher in AMI compared to AP at 3 and 12 hours (P<0.001 and P=0.003. Within the AMI group, reduction from 3 hours to all later time points was observed (all P≤0.001. Within the AP group, increase from baseline to 3 hours (P=0.022, followed by reductions thereafter (all P<0.05, was observed. PTX3 mRNA increased in the AMI group from 3 hours to days 7 and 14 in a relative manner of 62% and 73%, while a relative reduction from baseline to 3 and 12 hours of 29% and 37% was seen in the AP group. Conclusion. High circulating PTX3 levels shortly after PCI in AMI indicate that AMI itself influences PTX3 levels. PTX3 mRNA might be in response to fluctuations in circulating levels.

    Full Text Available Williams Syndrome (WS is a complex neurodevelopmental disorder associated with a mutation on chromosome 7. Patients with WS usually display dysmorphic facial and musculoskeletal features, congenital heart diseases, metabolic disturbances and cognitive impairment. Structural cardiovascular abnormalities are present in the majority of the children and may provide a substrate for perioperative Sudden Cardiac Death, as presented by several reports, something that creates a great challenge to the anesthetic conduct. We present the case of a 12-year old girl who required anesthetic care for surgical correction of an acquired kyphoscoliosis. Potential anesthesiological implications of WS are subsequently reviewed.

    The role of angiotensin-converting enzyme inhibitors (ACEI) in contrast-induced acute kidney injury (CI-AKI) is controversial. Some studies pointed out that it was effective in the prevention of CI-AKI, while some concluded that it was one risk for CI-AKI, especially for patients with pre-existing renal impairment. The purpose of this study was to assess the influence of benazepril administration on the development of CI-AKI in patients with mild to moderate renal insufficiency undergoing coronary intervention. One hundred and fourteen patients with mild to moderate impairment of renal function were enrolled before coronary angioplasty, who were randomly assigned to benazepril group (n = 52) and control group (n = 62). In the benazepril group, the patients received benazepril tablets 10 mg per day at least for 3 days before procedure. CI-AKI was defined as an increase of ≥ 25% in creatinine over the baseline value or increase of 0.5 mg/L within 72 hours of angioplasty. Patients were well matched with no significant differences at baseline in all measured parameters between two groups. The incidence of CI-AKI was lower by 64% in the benazepril group compared with control group but without statistical significance (3.45% vs. 9.68%, P = 0.506). Compared with benazepril group, estimated glomerular filtration rate (eGFR) level significantly decreased from (70.64 ± 16.38) ml · min⁻¹·1.73 m⁻² to (67.30 ± 11.99) ml · min⁻¹·1.73 m⁻² in control group (P = 0.038). There was no significant difference for the post-procedure decreased eGFR from baseline (ΔeGFR) between two groups (benazepril group (0.67 ± 12.67) ml · min⁻¹·1.73 m⁻² vs. control group (-3.33 ± 12.39) ml · min⁻¹·1.73 m⁻², P = 0.092). In diabetic subgroup analysis, ΔeGFR in benazepril group was slightly lower than that in the control group, but the difference was not statistically significant. Benazepril has a protective effect on mild to moderate impairment of renal function

    Full Text Available Objective: Cushing's syndrome (CS is extremely rare in morbidly obese patients. To date, no occurrences in obese patients with BMI above 60 kg/m2 have been reported in the literature. Case Report: This case report describes a patient who was admitted to the ward of the Clinical Division of Endocrinology and Metabolism of the Medical University of Vienna in preparation for bariatric surgery. The patient was a 49-year-old female who showed morbid obesity (BMI 61.6 kg/m2, hypertension, and substituted hypothyroidism. Preoperative work-up revealed CS due to an adrenal adenoma. Therefore, the patient underwent unilateral adrenalectomy followed by bariatric surgery 6 months later. Conclusion: Since undiagnosed CS might result in severe perioperative complications in a population already at increased risk, this case report underlines the importance of careful endocrine evaluation of morbidly obese patients. After all, even rare endocrine causes should be excluded.

    Dementia represents one of the most challenging health problems. Despite intense research, available therapies have thus far only achieved modest results. Deep brain stimulation (DBS) is an effective treatment option for some movement disorders and is under study for psychiatric applications. Recently, diencephalic DBS revealed selective effects on memory functions, another facet of subcortical DBS. To report a new DBS strategy for the modification of cognitive functions in a patient with severe Parkinson-dementia syndrome. Prospective study with double-blinded sham stimulation period. Departments of Stereotaxy and Functional Neurosurgery and Psychiatry and Psychotherapy, University of Cologne, Cologne, Germany. A 71-year-old man with slowly progressive Parkinson-dementia syndrome. Intervention We inserted 2 electrodes into the nucleus basalis of Meynert in addition to electrodes in the subthalamic nucleus. Main Outcome Measure Improvement of cognitive functions. Turning on the subthalamic nucleus electrodes improved motor symptoms but left cognitive performance almost unchanged. Turning on electrical stimulation of the nucleus basalis of Meynert resulted in markedly improved cognitive functions. The improvement in attention, concentration, alertness, drive, and spontaneity resulted in the patient's renewed enjoyment of former interests and enhanced social communication. Such a broad effect on cognition is consistent with ample experimental evidence revealing that the nucleus basalis of Meynert provides cholinergic innervation to the cortical mantle, complemented by glutaminergic and gamma-aminobutyric acid-transmitting projections from the basal forebrain. These projections provide background tuning facilitating cortical operations. Furthermore, nucleus basalis of Meynert stimulation paired with sensory stimuli can accomplish persistent reorganization of specific processing modules. The improvements in cognitive and behavioral performance in our patient are likely

    In patients undergoing elective partial pancreatectomy, our aim was to evaluate the effect of metabolic syndrome (MS) on postoperative mortality, morbidity, and utilization of hospital resources. Our hypothesis was that MS is associated with worse surgical outcomes after pancreatectomy. Fifteen thousand eight hundred thirty-one patients undergoing elective pancreatectomy from 2005 to 2012 were identified in the Participant User File of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Univariable and multivariable analyses were performed examining the association of MS (defined as body mass index ≥30 kg/m(2), hypertension requiring medications, and diabetes requiring medications and/or insulin) and risk of 30-day mortality, morbidity, and utilization of hospital resources (risk of blood transfusion in the first 72 h after pancreatectomy and prolonged hospital stay, defined as ≥13 days, which was the 75th percentile of this cohort). Multivariable logistic regression models controlled for age, sex, race, pancreatectomy type (distal versus proximal), smoking status, alcohol consumption, functional status, dyspnea, cardiovascular disease, hematocrit, INR, serum albumin, bilirubin, and creatinine. Stratified analyses were conducted by type of pancreatectomy and indication for pancreatectomy (benign versus malignant). On univariate analysis, 1070 (6.8%) patients had MS. MS was associated with increased postoperative morbidity, major morbidity, surgical site infection, septic shock, cardiac event, respiratory failure, pulmonary embolism, blood transfusion, and prolonged duration of hospital stay (P pancreatectomy (P = 0.465). When stratified by distal versus proximal pancreatectomy and benign versus malignant disease, the effect of MS on outcomes appears to be modified by type of pancreatectomy and indication with poorer outcomes observed for distal pancreatectomies and benign indications for resection. MS is an under

    Treatment of chronic low back pain with or without lower extremity pain continues to be a challenge. Epidural steroids are commonly utilized in patients after the failure of conservative treatment. The results of epidural steroid injections have been variable based on the pathophysiology, the route of administration, injected drugs, and utilization of fluoroscopy. In patients resistant to fluoroscopically directed epidural injections, percutaneous epidural adhesiolysis and percutaneous targeted delivery of injections with or without adhesiolysis has been recommended. Percutaneous adhesiolysis has been studied in chronic pain syndromes related to post laminectomy syndrome and spinal stenosis with encouraging results. There is a paucity of literature regarding the effectiveness of the targeted delivery of medications with or without epidural adhesiolysis in patients recalcitrant to epidural steroid injections without a history of surgery and spinal stenosis. A randomized, equivalence trial of percutaneous lumbar adhesiolysis and caudal epidural steroid injections in patients with low back and/or lower extremity pain without post surgery syndrome or spinal stenosis. An interventional pain management practice setting in the United States. The study is designed to evaluate the effectiveness of percutaneous epidural adhesiolysis in managing chronic low back and/or lower extremity pain in patients without post lumbar surgery syndrome or spinal stenosis and compare it with fluoroscopically directed caudal epidural steroid injections The study design includes 120 patients randomly assigned into 2 groups. Group I (60 patients), the control group, will receive caudal epidural injections with catheterization up to S3 with local anesthetic, steroids, and 0.9% sodium chloride solution; Group II (60 patients), the intervention group, will receive percutaneous adhesiolysis with target delivery of lidocaine, 10% hypertonic sodium chloride solution, and non-participate betamethasone

    The long-term risk associated with different coronary artery disease (CAD) presentations in women undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES) is poorly characterized. We pooled patient-level data for women enrolled in 26 randomized clinical trials. Of 11,577 women included in the pooled database, 10,133 with known clinical presentation received a DES. Of them, 5,760 (57%) had stable angina pectoris (SAP), 3,594 (35%) had unstable angina pectoris (UAP) or non-ST-segment-elevation myocardial infarction (NSTEMI), and 779 (8%) had ST-segment-elevation myocardial infarction (STEMI) as clinical presentation. A stepwise increase in 3-year crude cumulative mortality was observed in the transition from SAP to STEMI (4.9% vs 6.1% vs 9.4%; p <0.01). Conversely, no differences in crude mortality rates were observed between 1 and 3 years across clinical presentations. After multivariable adjustment, STEMI was independently associated with greater risk of 3-year mortality (hazard ratio [HR] 3.45; 95% confidence interval [CI] 1.99 to 5.98; p <0.01), whereas no differences were observed between UAP or NSTEMI and SAP (HR 0.99; 95% CI 0.73 to 1.34; p = 0.94). In women with ACS, use of new-generation DES was associated with reduced risk of major adverse cardiac events (HR 0.58; 95% CI 0.34 to 0.98). The magnitude and direction of the effect with new-generation DES was uniform between women with or without ACS (pinteraction = 0.66). In conclusion, in women across the clinical spectrum of CAD, STEMI was associated with a greater risk of long-term mortality. Conversely, the adjusted risk of mortality between UAP or NSTEMI and SAP was similar. New-generation DESs provide improved long-term clinical outcomes irrespective of the clinical presentation in women. Published by Elsevier Inc.

    Purpose: To describe the procedure of percutaneous vertebroplasty and to present our first clinical results of patients treated for benign or malignant painful vertebral body disease. Material and Methods: We performed percutaneous vertebroplasty in 31 painful lesions of the spine. Liquid bone cement was injected into the affected vertebral body using fluoroscopic guidance through a bilateral transpedicular approach. Etiology of the bone disease was assessed by biopsy. Pain intensity was assessed before and 1 week after the procedure by standardized catalogue. Results: Percutaneous vertebroplasty was performed in 17 thoracic and in 14 lumbar spine bodies of benign (n = 23) or malignant (n = 8) disease; no clinically relevant complications occurred. All patients reported significant pain relief 1 week after the intervention. One week after treatment, patients were pain-free in 15/31 vertebral bodies, and reported mild residual pain not necessitating narcotic medication in 16/31 cases. Conclusion: In accordance with the literature, percutaneous vertebroplasty proved to be a highly effective, minimal invasive interventional procedure to treat severely painful bone lesions of benign and malignant origin.

    Full Text Available Although soluble suppression of tumorigenicity 2 (sST2 in serum is known to be associated with ischemic heart disease and heart failure, data regarding its prognostic impact in ST-segment elevation myocardial infarction (STEMI is limited. We evaluated the prognostic impacts of serum sST2 and other serum biomarkers in STEMI patients undergoing primary percutaneous coronary intervention (PCI.Consecutive all 323 patients with STEMI that underwent primary PCI were enrolled. Blood tests and samples were obtained in an emergency room. The primary endpoint was 1-year major adverse cardiovascular and cerebrovascular events (MACCEs, defined as a composite of cardiovascular death, non-fatal MI, non-fatal stroke, and ischemia-driven revascularization.Mean age was 59.1±13.1 years (men 84%. MACCE (20 cardiovascular deaths, 7 non-fatal MI, 4 non-fatal stroke, 7 ischemia-driven revascularizations occurred in 38 patients (12%. After adjusting for confounding factors, Cox regression analysis revealed that high serum sST2 (>75.8 ng/mL mean value, adjusted hazard ratio 2.098, 95% CI 1.008-4.367, p = 0.048 and high serum NT-proBNP level (>400 pg/mL, adjusted hazard ratio 2.606, 95% CI 1.086-6.257, p = 0.032 at the time of presentation independently predicted MACCE within a year of primary PCI. Furthermore, when high serum sST2 level was combined with high serum NT-proBNP level, the hazard ratio of MACCE was highest (adjusted hazard ratio 7.93, 95% CI 2.97-20.38, p<0.001.Elevated serum levels of sST2 or NT-proBNP at the time of presentation were found to predict 1-year MACCE independently and elevated serum levels of sST2 plus NT-proBNP were associated with even poorer prognosis in patients with STEMI undergoing primary PCI.

    Contrast-induced acute kidney injury (CI-AKI) is associated with poor outcome. Whether this association differs in stable coronary artery disease (CAD) as compared to acute coronary syndrome (ACS) patients is unknown. Definitions and Methods: PRODIGY trial patients were defined as stable CAD or ACS according to the initial presentation. CI-AKI was defined as an increase (Δ) of serum creatinine (SCr) ≥25% above baseline. Two endpoints were considered: all-cause death and the composite of death, stroke, or myocardial infarction (MI). The interaction between CI-AKI, clinical setting, and the impact of increasing ΔSCr% cut-offs were also explored. Two thousand three patients were enrolled in the PRODIGY trial, 85 patients were excluded for missing SCr data, leading to a population of 1,918 patients. CI-AKI incidence was 6.7% in stable CAD and 12.2% in ACS patients. CI-AKI was associated with all-cause mortality [adjusted hazard ratio (aHR) of 2.05, 95% confidence interval (CI) 1.38-3.05, P  0.001]. In a large, contemporary, all-comers percutaneous coronary intervention population, CI-AKI was associated with an increased risk of all-cause death and the composite of death, stroke, or MI. While CI-AKI is more common in ACS than in stable CAD patients, its adjusted prognostic impact on the composite endpoint appears to be more pronounced in patients with stable CAD. © 2015 Wiley Periodicals, Inc.

    Purpose: To describe a combined procedure of repositioning and leaving in situ a central venous catheter followed by immediate percutaneous treatment of associated superior vena cava syndrome (SVCS). Methods: Eight patients are presented who have central venous catheter-associated SVCS (n = 6 Hickman catheters, n = 2 Port-a-cath) caused by central vein stenosis (n = 4) or concomitant thrombosis (n = 4). With the use of a vascular snare introduced via the transcubital or transjugular approach, the tip of the central venous catheter could be engaged, and repositioned after deployment of a stent in the innominate or superior vena cava. Results: In all patients it was technically feasible to reposition the central venous catheter and treat the SVCS at the same time. In one patient flipping of the Hickman catheter in its original position provoked dislocation of the released Palmaz stent, which could be positioned in the right common iliac vein. Conclusion: Repositioning of a central venous catheter just before and after stent deployment in SVCS is technically feasible and a better alternative than preprocedural removal of the vascular access

    Unprotected left main (ULM) coronary artery disease is encountered in 3%-10% of coronary angiograms and is associated with high mortality. The survival of patients with ULM disease presenting with acute coronary syndromes (ACS) depends on different variables and is lowest in those with cardiogenic shock (CS). The aim of the present study was to estimate the impact of baseline characteristics on the subsequent clinical outcome in patients treated by percutaneous coronary intervention (PCI) of ULM for ACS. One hundred and thirty-four patients were retrieved from our database and followed by phone or physician visit. Patients were classified into two groups according to their presentation (CS/STEMI group: patients presenting with CS or ST-elevation myocardial infarction; NSTEMI/UA group: patients with non-STEMI or unstable angina). Data collected were baseline characteristics, procedural information, and clinical outcome. The primary endpoint was all-cause mortality at 6-month follow-up. The secondary end point was a composite of cardiac death, myocardial infarction, and any repeat revascularisation, i.e., major adverse cardiac events (MACE). Kaplan-Meier curves were computed for survival. Logistic regression determined that hypercholesterolaemia (OR 6.22, p=0.03), high pre-procedural TIMI score (OR 3.89, p=0.01), preserved left ventricular ejection fraction (OR 1.07, p=0.01) and LM as culprit lesion (OR 8.57, p=0.01) protected against development of CS. Primary outcome occurred in 44% of patients in the CS/STEMI group compared to 6% in the NSTEMI/UA group (p<0.001). MACE were observed in 30 patients (48%) of the CS/STEMI group and in 12 patients (19%) of the NSTEMI/UA group (p=0.001). Acute coronary syndrome due to critical ULM stenosis is associated with high mortality even after successful PCI. Patients presenting with CS or STEMI are at particular risk.

The QoL was assessed using the MacNew Heart Disease Health-Related Quality of Life questionnaire. The group of females scored lower in all the domains of the MacNew Heart Disease Health-Related Quality of Life questionnaire in the initial measurement (B1, in the measurement after 6 months (B2, and in the long-term follow-up measurement (36 months – B3. Despite the fact that both groups achieved improved QoL, its values were higher in the males. The average growth rate of the QoL score in the period from the sixth month to 36th month was higher in females than in males. In the univariate and multivariate analyses, significant independent predictors with a negative influence on the long-term QoL score included female sex (Ρ=−0.190, β=−0.21, age >60 years (Ρ=−0.255, β=−0.186, and diabetes (Ρ=−0.216, β=−0.216.Conclusion: In a 36-month follow-up of ACS patients treated with PCI, there were no statistically significant differences in QoL between sexes. In the entire cohort, there was improvement in QoL, which was higher in the case of the females studied. For the entire group, significant independent determinants of lower QoL 3

    Dual antiplatelet therapy is essential in patients undergoing percutaneous coronary intervention with stent implantation. Hypersensitivity to acetylsalicylic acid (ASA) limits treatment options. Desensitization to ASA has classically been studied in patients with respiratory tract disease. Over the last years, many protocols have been described about ASA desensitization in patients with ischemic heart disease, including acute coronary syndrome and the need for coronary stent implantation. It is important to know the efficacy and safety of ASA desensitization in these patients. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

    adverse psychological characteristics on the prognosis of individuals submitted to percutaneous coronary interventions. No study has addressed this issue in Brazil. OBJECTIVE: To investigate the prevalence of depression, anxiety, psychological stress, and Type D personality and its association with cardiovascular events in patients undergoing percutaneous coronary interventions. METHODS: Psychological characteristics were evaluated by scales: Beck Depression Inventory, Beck Anxiety Inventory, Lipp Inventory for Stress Symptoms for Adults and Type D Personality Scale. The end-point of this study was the occurrence of major cardiovascular events in one-year follow-up. RESULTS: During March and May 2006, 137 patients were included. Type D personality was identified in 34% of the cases, 29% presented anxiety, 25% presented depression and 70% of the patients presented stress. In relation to the frequency of psychological characteristics according to the occurrence of major adverse cardiovascular events, there was no statistical difference between both groups of patients regarding depression (29% vs. 26% p = 0.8, anxiety (33% vs. 23% p = 0.3, stress (76% vs. 65% p = 0.3, and Type D personality (33% vs. 32% p = 0.9. However, the negative affectivity score was significantly higher in the group of patients presenting events (13.9 vs. 9.8 p = 0.01. CONCLUSION: In patients submitted to percutaneous coronary interventions, the prevalence of adverse psychological characteristics was high. One-year major cardiovascular adverse events were associated with baseline negative affectivity, but not with the other psychological characteristics studied

    Full Text Available We present the first case of small cell lung cancer with Lambert-Eaton myasthenic syndrome during hemodialysis (HD. A 72-year-old male patient receiving HD experienced progressive muscle weakness. He was diagnosed with small cell lung cancer with Lambert-Eaton myasthenic syndrome due to an increased serum level of anti-voltage-gated calcium channel antibody and aspiration cytology on endobronchial ultrasonography for the swelling of a subcarinal lymph node. He received chemotherapy consisting of carboplatin (300 mg/m2 and etoposide (50 mg/m2, to which he had a partial response. However, the second therapy course could not be administered because of the unexpected development of severe hematological adverse events, which also prevented him from undergoing further HD. This case indicates that caution should be taken when using chemotherapy for such patients because of hypotension due to chemotherapy, with which it is impossible to undergo HD.

    Full Text Available We present a case of severe tracheobronchial compression from a complex aorto-subclavian aneurysm in a patient with Turner′s syndrome undergoing open surgical repair. Significant airway compression is a challenging situation and requires careful preoperative preparation, maintenance of spontaneous breathing when possible, and consideration of having an alternative source of oxygenation and circulation established prior to induction of general anesthesia. Cardiopulmonary monitoring is essential for safe general anesthesia and diagnosis of unexpected intraoperative events.

    We evaluated the effects of the Xuefu Zhuyu capsule (XFZY) and the Shengmai capsule (SM) on the evolution of syndromes and inflammatory markers in patients with unstable angina pectoris (UAP) after percutaneous coronary intervention (PCI). Ninety patients with UAP after PCI were randomly and equally assigned to three groups: the XFZY group, the SM group, and the placebo group, with 30 patients in each group. Six syndrome factors (including Qi deficiency, yin deficiency, yang deficiency, blood stasis, phlegm, and Qi stagnation) and 4 inflammatory markers (high-sensitivity C-reactive protein (Hs-CRP), endothelins-1 (ET-1), matrix metalloproteinases-9 (MMP-9), and homocysteine (Hcy)) were observed at week 0 and at the 1st, 4th and 12th weeks. In conclusion, the evolution of syndromes present in patients with UAP after PCI followed these trends (1) The deficiency syndromes gradually increased during a 12-week period, but the excess syndromes first gradually decreased and then mildly increased after PCI. (2) XFZY and SM can prevent excess syndromes from increasing in the later stages and prevent deficiency syndromes from increasing in all stages. (3) XFZY and SMcan reduce the levels of the inflammatory markers, especially in the later stages after PCI. PMID:23737852

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

    The purpose of this study was to examine the association between statin use by individuals and the risk for incident diabetes mellitus in patients with acute coronary syndrome (ACS) following percutaneous coronary intervention (PCI). We conducted a retrospective cohort study of patients who were hospitalized for ACS between January 1, 2006, and December 31, 2010, and who had undergone PCI (n=30,665); the data were retrieved from the Taiwan National Health Insurance Research Database. A propensity score technique was used to establish a 1:1 matched cohort for statin users and non-statin users (n=9043 for each group). The risk for incident diabetes mellitus in statin users compared to non-statin users for patients with ACS after PCI was estimated by the multivariable Cox proportional hazards regression model. Statin use was associated with a significant increase of 27% in the risk for new-onset diabetes mellitus (adjusted hazard ratio [HR] 1.27, 95% CI 1.14 to 1.41) compared to non-statin use in the matched cohort. The matched cohort analysis indicated that almost all individual statins were associated with a statistically significant increase in the risk for new-onset diabetes mellitus compared to those without statin use. Our study indicated an association between increased risk for new-onset diabetes mellitus and statin use. Because the benefits of statins in prevention of morbidity and mortality in patients with ACS are well-established, clinical decision making should not be changed for patients with existing cardiovascular disease in whom statin therapy is recommended.

    Neurogenic thoracic outlet syndrome (NTOS) results from compression of the brachial plexus by the clavicle, first rib, and scalene muscles and may develop secondary to repetitive motion of the upper extremity. Athletes routinely perform repetitive motions, and sports requiring significant arm and shoulder use may put the participant at increased risk for NTOS. Competitive athletes who develop NTOS may require first rib resection and scalenectomy (FRRS) for symptomatic relief. However, the effectiveness of FRRS has not previously been studied in this vulnerable population. This is a cross-sectional study of competitive athletes with NTOS who received FRRS by the senior author between 2009 and 2014. Eligible patients were contacted by phone and invited to complete a nine-item survey assessing the long-term effects of FRRS on pain medication use, postoperative physical therapy duration, patient satisfaction, symptom relief, activities of daily living, athletic performance, time to return of athletic performance, and need for other operations. Multivariate analyses of the following risk factors were performed: age, pectoralis minor release, preoperative narcotic use, athletic shutdown, and involvement in a throwing sport. There were 232 competitive athletes who met the inclusion criteria, and 67 of these (age, 14-48 years; 35 male; 99% white) responded to the survey. The average time between surgery and survey completion was 3.9 years (range, 2.2-7.0 years). The most frequent sports conducted by this group were baseball and softball (n = 44 [66%]), volleyball (n = 7 [10%]), and cheerleading and gymnastics (n = 5 [7%]), ranging from high-school to professional levels. The survey results revealed that 96% were improved in pain medication use, 75% would undergo FRRS on the contralateral side if needed, 82% had resolution of symptoms, and 94% were able to perform activities of daily living without limitation; 70% returned to the same or better level of athletic

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

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

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

    The effects of loading doses of statins on clinical outcomes in patients with acute coronary syndrome (ACS) and planned invasive management remain uncertain. To determine if periprocedural loading doses of atorvastatin decrease 30-day major adverse cardiovascular events (MACE) in patients with ACS and planned invasive management. Multicenter, double-blind, placebo-controlled, randomized clinical trial conducted at 53 sites in Brazil among 4191 patients with ACS evaluated with coronary angiography to proceed with a percutaneous coronary intervention (PCI) if anatomically feasible. Enrollment occurred between April 18, 2012, and October 6, 2017. Final follow-up for 30-day outcomes was on November 6, 2017. Patients were randomized to receive 2 loading doses of 80 mg of atorvastatin (n = 2087) or matching placebo (n = 2104) before and 24 hours after a planned PCI. All patients received 40 mg of atorvastatin for 30 days starting 24 hours after the second dose of study medication. The primary outcome was MACE, defined as a composite of all-cause mortality, myocardial infarction, stroke, and unplanned coronary revascularization through 30 days. Among the 4191 patients (mean age, 61.8 [SD, 11.5] years; 1085 women [25.9%]) enrolled, 4163 (99.3%) completed 30-day follow-up. A total of 2710 (64.7%) underwent PCI, 333 (8%) underwent coronary artery bypass graft surgery, and 1144 (27.3%) had exclusively medical management. At 30 days, 130 patients in the atorvastatin group (6.2%) and 149 in the placebo group (7.1%) had a MACE (absolute difference, 0.85% [95% CI, -0.70% to 2.41%]; hazard ratio, 0.88; 95% CI, 0.69-1.11; P = .27). No cases of hepatic failure were reported; 3 cases of rhabdomyolysis were reported in the placebo group (0.1%) and 0 in the atorvastatin group. Among patients with ACS and planned invasive management with PCI, periprocedural loading doses of atorvastatin did not reduce the rate of MACE at 30 days. These findings do not support the routine use

    To compare 30 and 90 day real-world acute myocardial infarction (AMI) and bleeding related rehospitalization rates in acute coronary syndrome (ACS) patients receiving percutaneous coronary intervention (PCI; ACS-PCI) treated with clopidogrel or prasugrel. Using the Premier hospital database, ACS-PCI patients receiving a drug-eluting (DES) or bare-metal (BMS) stent and clopidogrel or prasugrel from July 2009 to June 2011 were analyzed. Patients were included based on the prasugrel US prescribing information (USPI), excluding patients with a history of transient ischemic attack/stroke and patients ≥75 years without diabetes or prior MI. The primary endpoint was 30 day adjusted AMI rehospitalization rate. Secondary endpoints included 90 day AMI and 30 and 90 day bleeding-related rehospitalization rates. Treatment comparisons were adjusted using propensity score stratification. At the index event, prasugrel patients (N = 9404) differed from clopidogrel patients (N = 74,163) by having a lower risk of comorbid conditions associated with bleeding, being more likely younger and male, having ST-elevation MI and receiving a DES. For clopidogrel and prasugrel, respectively, the observed AMI-related rehospitalization rates were 4.7% and 3.9% at 30 days (p < 0.0001) and 6.3% and 5.1% at 90 days (p < 0.0001). After adjustment, prasugrel was associated with ∼10% lower odds of AMI-related rehospitalization (30 days: OR = 0.892 [95% CI: 0.798, 0.998]; 90 days, OR = 0.901 [95% CI: 0.817, 0.994]). Adjusted bleeding-related rehospitalization rates were similar to each other (OR = 1.035 at 30 days [95% CI: 0.765, 1.399]; OR = 0.922 at 90 days [95% CI: 0.725, 1.172]). Treatment adherence was not assessed. Bleeding events not resulting in a hospitalization (e.g. office, outpatient, or emergency room visits), deaths outside the hospital, or readmissions to a hospital outside of the Premier alliance were not captured in the database.

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

    Estimated glomerular filtration rate (eGFR) is a predictor of outcome among patients with non-ST-elevation acute coronary syndrome (NSTE-ACS), but which estimation formula provides the best long-term risk stratification in this setting is still unclear. We compared the prognostic performance of four creatinine-based formulas for the prediction of 10-year outcome in a NSTE-ACS population treated by percutaneous coronary intervention. In 222 NSTE-ACS patients submitted to percutaneous coronary intervention, eGFR was calculated using four formulas: Cockcroft-Gault, re-expressed modification of diet in renal disease (MDRD), chronic kidney disease epidemiology collaboration (CKD-Epi), and Mayo-quadratic. Predefined endpoints were all-cause death and a composite of cardiovascular death, non-fatal reinfarction, clinically driven repeat revascularisation, and heart failure hospitalisation. The different eGFR values showed poor agreement, with prevalences of renal dysfunction ranging from 14% to 35%. Over a median follow-up of 10.2 years, eGFR calculated by the CKD-Epi and Mayo-quadratic formulas independently predicted outcome, with an increase in the risk of death and events by up to 17% and 11%, respectively, for each decrement of 10 ml/min/1.73 m 2 . The Cockcroft-Gault and MDRD equations showed a borderline association with mortality and did not predict events. When compared in terms of goodness of fit, discrimination and calibration, the Mayo-quadratic outperformed the other formulas for the prediction of death and the CKD-Epi showed the best performance for the prediction of events (net reclassification improvement values 0.33-0.35). eGFR is an independent predictor of long-term outcome in patients with NSTE-ACS treated by percutaneous coronary intervention. The Mayo-quadratic and CKD-Epi equations might be superior to classic eGFR formulas for risk stratification in these patients.

    Low cardiac output syndrome remains a serious complication, and accounts for substantial morbidity and mortality in the postoperative course of paediatric patients undergoing surgery for congenital heart disease. Standard prophylactic and therapeutic strategies for low cardiac output syndrome are based mainly on catecholamines, which are effective drugs, but have considerable side effects. Levosimendan, a calcium sensitiser, enhances the myocardial function by generating more energy-efficient myocardial contractility than achieved via adrenergic stimulation with catecholamines. Thus potentially, levosimendan is a beneficial alternative to standard medication for the prevention of low cardiac output syndrome in paediatric patients after open heart surgery. To review the efficacy and safety of the postoperative prophylactic use of levosimendan for the prevention of low cardiac output syndrome and mortality in paediatric patients undergoing surgery for congenital heart disease. We identified trials via systematic searches of CENTRAL, MEDLINE, Embase, and Web of Science, as well as clinical trial registries, in June 2016. Reference lists from primary studies and review articles were checked for additional references. We only included randomised controlled trials (RCT) in our analysis that compared prophylactic levosimendan with standard medication or placebo, in infants and children up to 18 years of age, who were undergoing surgery for congenital heart disease. Two review authors independently extracted data and assessed risk of bias according to a pre-defined protocol. We obtained additional information from all but one of the study authors of the included studies. We used the five GRADE considerations (study limitations, consistency of effect, imprecision, indirectness, and publication bias) to assess the quality of evidence from the studies that contributed data to the meta-analyses for the prespecified outcomes. We created a 'Summary of findings' table to

    Full Text Available Background and Objective. Drug dependence is one of the serious problems around the world. Saffron is one of those beneficial medicinal plants which is embedded with a similar mechanism to methadone (e.g., inhibition of serotonin reuptake. Thus, it can be helpful in reducing the withdrawal symptoms. The aim of this study was to reduce the daily dose of methadone usage and reduce its side effects using saffron in the form of medicinal supplements. Methodology. This study was categorized as a clinical trial. Accordingly, 44 clients of addiction treatment centers in Sabzevar parish were randomly selected to participate in this study in 2016–2017. While the experimental group was treated with methadone syrup and self-made saffron capsules, the control group received methadone syrup and placebo capsules. Results. The results showed that the use of saffron and methadone alleviated the symptoms of withdrawal syndrome (p<0.001. Conclusion. Having reviewed the research participants, it was indicated that the introduction of saffron alleviated the symptoms of withdrawal syndrome in patients undergoing maintenance treatment for opioid addiction. Thus, it seems rational to make use of saffron in combination with methadone in order to alleviate the symptoms of withdrawal syndrome.

    Objective: To present a latest procedures for portal hypertension with preliminary results and evaluate the technical feasibility and efficacy of the portacaval shunt creation through percutaneous transhepatic approach with its potential clinical significance. Methods: Nineteen patients with portal hypertension (17 men; mean age 57 years, range 32-73) were referred for PTPS procedure because of bleeding varices (n=16), intractable ascites (n=2), and hepatopulmonary syndrome (n=1). The severity of liver disease was Child's B in 4 and Child's C in 15. The PTPS was created by a percutaneous transhepatic puncture through left portal vein to the IVC and a polytetrafluoroethylene (PTFE) stent-grafts was placed through a transhepatic approach. Results: Technical and functional successes were achieved in all patients-arerage without any procedure-related complications. The postprocedural portal vein-IVC gradients decreased with a mean 13 cmH 2 O and with average 216 days of follow-up showing no recurrent variceal bleeding and refractory ascites. The primary patency ratefor 365 days was 94.8%, obviously higher than classical TIPS. Conclusions: Portacaval shunt creation using the percutaneous transhepatic technique is secure and feasible with favorable primary patency due to the a straight line shunt construction and provide a good alternative to the standard portosystemic shunt in difficult or impossible circumstances.

    Full Text Available Ultra rapid opioid detoxification (UROD is one of the new methods of detoxification. This method of detoxification involves putting patients under general anesthesia and actively giving them opioid antagonists. The objective of this study was to evaluate effects of anesthesia duration in UROD on severity of withdrawal syndrome. Sixty addicted patients seeking UROD procedure assigned randomly to one of the 2hr, 4hr or 6hr anesthesia duration groups. Premedication and anesthesia procedure (induction and maintenance were the same for three groups. Detoxification was done for all patients with 50 mg oral naltroxane (prior to induction and 20 mg intravenous naloxane (8 mg/bolus and 12 mg/infusion. Blood pressure, heart rate and respiratory rate were automatically measured and recorded every 5 minutes. The severity of withdrawal syndrome was measured and recorded every one hour during anesthesia, 2hours post-anesthesia, and 12 and 24 hours following the induction of anesthesia according to the Wang Scale modified by Lomier (WSMBL. Patients aged 20-58 in three groups. Three cases experienced delirium after detoxification that lasted 24 hours in one. Severity of withdrawal syndrome in patients of groups 2, 4 and 6 hour were 8.7, 7.4 and 5.1 respectively during anesthesia and 12.3, 11.1 and 13.9 after 18 hours of anesthesia. Results of this study showed that, in standard settings, UROD is a safe method for detoxification and has low complications. The withdrawal symptoms during and after anesthesia are low. Shortening the duration of anesthesia has no affect on severity of withdrawal syndrome during and after anesthesia.

    Full Text Available We investigated the clinical usefulness of oral supplementation with a combination product containing alpha-lipoic acid, curcumin phytosome, and B-group vitamins in 180 patients with carpal tunnel syndrome (CTS, scheduled to undergo surgical decompression of the median nerve. Patients in Group A (n=60 served as controls and did not receive any treatment either before or after surgery. Patients in Group B (n=60 received oral supplementation twice a day for 3 months both before and after surgery (totaling 6 months of supplementation. Patients in Group C (n=60 received oral supplementation twice a day for 3 months before surgery only. Patients in Group B showed significantly lower nocturnal symptoms scores compared with Group A subjects at both 40 days and 3 months after surgery (both P values <0.05. Moreover, patients in Group B had a significantly lower number of positive Phalen’s tests at 3 months compared with the other study groups (P<0.05. We conclude that oral supplementation with alpha-lipoic acid, curcumin phytosome, and B-group vitamins twice a day both before and after surgery is safe and effective in CTS patients scheduled to undergo surgical decompression of the median nerve.

    2010-01-01

    Full Text Available Metastatic liver resection following cytoreductive chemotherapy is an accepted treatment for oligometastatic tumor diseases. Although pulmonary complications are frequently reported in patients undergoing liver surgery including liver transplantation, life-threatening acute respiratory failures in the absence of aspiration, embolism, transfusion-related acute lung injury (TRALI, pulmonary infection, or an obvious source of systemic sepsis are rare. We performed an extensive clinical review of a patient undergoing metastatic liver resection who had a clinical course compatible to an acute respiratory distress syndrome (ARDS without an obvious cause except for the surgical procedure and multiple preoperative chemotherapies. We hypothesize that either the surgical procedure mediated by cytokines and tumor necrosis factor or possible toxic effects of oxygen applied during general anesthesia were associated with life-threatening respiratory failure in the patient. Discrete and subclinical inflammated alveoli (probably due to multiple preoperative chemotherapies with substances at potential risk for interstitial pneumonitis as well as chest radiation might therefore be considered as risk factors.

Correctly put into practice by trained professionals, this procedure can prevent patients having to undergo another series of treatments which bear greater risks, to have a longer hospital stay, or even, depending on the case, to have to undergo an operation. Nurses in a radiological unit have an overwhelming role in every step of a percutaneous abscess drainage, a role which can not be carried out by any other personnel. To achieve being up to date in this technique and to perform our function as nurses in the use of this technique are the main objectives of this review.

    Full Text Available Objectives: This study aims to investigate trends of cardiovascular disease (CVD risk factor profiles over 17 years in percutaneous coronary intervention (PCI patients at the Mayo Clinic. Methods: We performed a time-trend analysis within the Mayo Clinic PCI Registry from 1994 to 2010. Results were the incidence and prevalence of CVD risk factors as estimate by the Framingham risk score. Results: Between 1994 and 2010, 25 519 patients underwent a PCI. During the time assessed, the mean age at PCI became older, but the gender distribution did not change. A significant trend towards higher body mass index and more prevalent hypercholesterolemia, hypertension, and diabetes was found over time. The prevalence of current smokers remained unchanged. The prevalence of ever-smokers decreased among males, but increased among females. However, overall CVD risk according to the Framingham risk score (FRS and 10-year CVD risk significantly decreased. The use of most of medications elevated from 1994 to 2010, except for β-blockers and angiotensin converting enzyme inhibitors decreased after 2007 and 2006 in both baseline and discharge, respectively. Conclusions: Most of the major risk factors improved and the FRS and 10-year CVD risk declined in this population of PCI patients. However, obesity, history of hypercholesterolemia, hypertension, diabetes, and medication use increased substantially. Improvements to blood pressure and lipid profile management because of medication use may have influenced the positive trends.

    Full Text Available Werner′s syndrome (WS is a rare autosomal recessive disorder with multisystem manifestations of premature aging from the second decade of life. Cataract is one of the features of WS. Cataract surgery is complicated with postoperative wound dehiscence and bullous keratopathy when the surgery is done by intracapsular or conventional extracapsular method. We report the short-term result of phacoemulsification and Neodymimum Yettrium-Aluminum-Garnet laser (Nd YAG capsulotomy in a case of WS with bilateral cataracts. Postoperatively and post capsulotomy, there was no change in the endothelial cell morphology. There was an 8.6% decrease in endothelial cell count at the end of 15 months postoperatively and 11 months post YAG capsulotomy. This decrease is within the acceptable range of cell loss after phacoemulsification and YAG capsulotomy. To the best of our knowledge, this is the first reported case of YAG laser capsulotomy in WS.

    Rapid maxillary expansion (RME) is a widely used practice in orthodontics. Scientific evidence shows that RME can be helpful in modifying the breathing pattern in mouth-breathing patients. In order to promote the restoration of physiological breathing we have developed a rehabilitation program associated with RME in children. The aim of the study was a literature review and a model of orofacial rehabilitation in children with obstructive sleep apnea undergoing treatment with rapid maxillary expansion. Muscular training (local exercises and general ones) is the key factor of the program. It also includes hygienic and behavior instructions as well as other therapeutic procedures such as rhinosinusal washes, a postural re-education (Alexander technique) and, if necessary, a pharmacological treatment aimed to improve nasal obstruction. The program should be customized for each patient. If RME is supported by an adequate functional rehabilitation, the possibility to change the breathing pattern is considerably amplified. Awareness, motivation and collaboration of the child and their parents, as well as the cooperation among specialists, such as orthodontist, speech therapist, pediatrician and otolaryngologist, are necessary conditions to achieve the goal.

    Guidelines recommendations regarding anticoagulant therapy after percutaneous coronary intervention (PCI) among patients with atrial fibrillation (AF) rely on retrospective, nonrandomized observational data. Currently, patients are treated with triple-therapy (dual antiplatelet therapy [DAPT] + oral anticoagulation therapy), but neither the duration of DAPT nor the level of anticoagulation has been studied in a randomized fashion. Recent studies also suggest dual pathway therapy with clopidogrel plus oral anticoagulation therapy may be superior, and other studies suggest that novel oral anticoagulants such as rivaroxaban may further improve patient outcomes. PIONEER AF-PCI (ClinicalTrials.gov NCT01830543) is an exploratory, open-label, randomized, multicenter clinical study assessing the safety of 2 rivaroxaban treatment strategies and 1 vitamin K antagonist (VKA) treatment strategy in subjects who have paroxysmal, persistent, or permanent nonvalvular AF and have undergone PCI with stent placement. Approximately 2,100 subjects will be randomized in a 1:1:1 ratio to receive either rivaroxaban 15 mg once daily plus clopidogrel 75 mg daily for 12 months (a WOEST trial-like strategy), or rivaroxaban 2.5 mg twice daily (with stratification to a prespecified duration of DAPT 1, 6, or 12 months, an ATLAS trial-like strategy), or dose-adjusted VKA once daily (with stratification to a prespecified duration of DAPT 1, 6, or 12 months, traditional triple therapy). All patients will be followed up for 12 months for the primary composite end point of Thrombolysis in Myocardial Infarction major bleeding, bleeding requiring medical attention, and minor bleeding (collectively, clinically significant bleeding). The PIONEER AF-PCI study is the first randomized comparison of VKA vs novel oral anticoagulant therapy in patients with NVAF receiving antiplatelet therapy after PCI to assess the relative risks of bleeding complications.

    Full Text Available Background: A retrospective study has shown lesser days of hospital stay in patients with increased levels of intra-operative end-tidal carbon dioxide (ETCO 2 . It is probable that hypercapnia may exert its beneficial effects on patients′ outcome through optimization of global hemodynamic and tissue oxygenation, leading to a lower rate of post-operative complications. This study was designed to test the hypothesis that higher values of intra-operative ETCO 2 decrease the rate of post-operative complications. Materials and Methods: In this randomized, double-blind clinical trial, 78 adult patients scheduled for percutaneous nephrolithotomy (PCNL were prospectively enrolled and randomly divided into three groups. ETCO 2 was set and maintained throughout the procedure at 31-33, 37-39 and 43-45 mmHg in the hypocapnia, normocapnia and hypercapnia groups, respectively. The rates of post-operative complications were compared among the three groups. Results: Seventy-five patients completed the study (52 male and 23 female. Ten (38.5%, four (16% and two (8.3% patients developed post-operative vomiting in the hypocapnia, normocapnia and hypercapnia groups, respectively (P = 0.025. The nausea score was significantly lower in the hypercapnic group compared with the other groups (3.9 ± 1.8, 3.2 ± 2.1 and 1.3 ± 1.8 in the hypocapnia, normocapnia and hypercapnia groups, respectively; P = 0.000. Time to return of spontaneous respiration and awakening were significantly decreased in the hypercapnia group compared with the other groups (P < 0.01. Conclusion: Mild intra-operative hypercapnia has a protecting effect against the development of post-operative nausea and vomiting and decreases the duration of emergence and recovery from general anesthesia.

    Besides contrast-induced acute kidney injury(CI-AKI), adscititious vital organ damage such as hypoxic liver injury(HLI) may affect the survival in patients with ST-elevation myocardial infarction (STEMI). We sought to evaluate the prognostic impact of CI-AKI and HLI in STEMI patients who underwent primary percutaneous coronary intervention (PCI). A total of 668 consecutive patients (77.2% male, mean age 61.3±13.3 years) from the INTERSTELLAR STEMI registry who underwent primary PCI were analyzed. CI-AKI was defined as an increase of ≥0.5 mg/dL in serum creatinine level or 25% relative increase, within 48h after the index procedure. HLI was defined as ≥2-fold increase in serum aspartate transaminase above the upper normal limit on admission. Patients were divided into four groups according to their CI-AKI and HLI states. Major adverse cardiovascular and cerebrovascular events (MACCE) defined as a composite of all-cause mortality, non-fatal MI, non-fatal stroke, ischemia-driven target lesion revascularization and target vessel revascularization were recorded. Over a mean follow-up period of 2.2±1.6 years, 94 MACCEs occurred with an event rate of 14.1%. The rates of MACCE and all-cause mortality were 9.7% and 5.2%, respectively, in the no organ damage group; 21.3% and 21.3% in CI-AKI group; 18.5% and 14.6% in HLI group; and 57.7% and 50.0% in combined CI-AKI and HLI group. Survival probability plots of composite MACCE and all-cause mortality revealed that the combined CI-AKI and HLI group was associated with the worst prognosis (pINTERSTELLAR ClinicalTrials.gov number, NCT02800421.).

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

    To assess subclavian vein (SCV) patency and long-term functional outcomes following surgical decompression of the thoracic outlet (SDTO) for Paget-Schroetter Syndrome (PSS). Between January 1978 and January 2013, we identified 33 patients with PSS who underwent SDTO. Demographic, clinical and radiological data were extracted from electronic databases and patient records. All patients were invited to update their follow-up data during dedicated outpatient visits between October and December 2013. Outcome measures included long-term SCV patency and clinical success rates during follow-up. Clinical success was defined as the combined absence of functional symptoms and patient's ability to maintain normal professional activities at final follow-up. The QuickDASH score was also determined. The study population comprised 17 men and 16 women (mean age 34 years; range: 14-53 years) with PSS. Diagnosis was reached by venography (29 cases) or duplex scan (4 cases). SDTO was performed via the transaxillary route (25 cases) or using the combined supra-infraclavicular approach (8 cases). The procedure was carried out within 10 days in 13 patients (early-group), and between 30 to 120 days in the remaining 20 patients (late-group). The former had SCV recanalization obtained actively by thrombolysis (3 cases), thrombectomy (9 cases) or endovenectomy followed by patch venoplasty (1 case). The latter were maintained under chronic oral anticoagulation to allow SCV recanalization. There was neither postoperative death nor major bleeding complications. At a median follow-up of 240 months, 11 SCV remained patent in the early group, while in the other there was 3 re-occlusions, 4 residual stenoses and 5 chronic SCV occlusions. Clinical success was achieved in 73% of patients for the whole cohort, but was significantly better in patients operated on in the early stages (100% vs. 55%; P=0.005). The mean Quick Disabilities of the Arm, Shoulder, and Hand Score was 3.5 (95% CI: 1.5-5.4) in

    Low cardiac output syndrome after cardiac surgery is associated with high morbidity and mortality in patients with impaired left ventricular function. To assess the ability of preoperative levosimendan to prevent postoperative low cardiac output syndrome. Randomized, double-blind, placebo-controlled trial conducted in 13 French cardiac surgical centers. Patients with a left ventricular ejection fraction less than or equal to 40% and scheduled for isolated or combined coronary artery bypass grafting with cardiopulmonary bypass were enrolled from June 2013 until May 2015 and followed during 6 months (last follow-up, November 30, 2015). Patients were assigned to a 24-hour infusion of levosimendan 0.1 µg/kg/min (n = 167) or placebo (n = 168) initiated after anesthetic induction. Composite end point reflecting low cardiac output syndrome with need for a catecholamine infusion 48 hours after study drug initiation, need for a left ventricular mechanical assist device or failure to wean from it at 96 hours after study drug initiation when the device was inserted preoperatively, or need for renal replacement therapy at any time postoperatively. It was hypothesized that levosimendan would reduce the incidence of this composite end point by 15% in comparison with placebo. Among 336 randomized patients (mean age, 68 years; 16% women), 333 completed the trial. The primary end point occurred in 87 patients (52%) in the levosimendan group and 101 patients (61%) in the placebo group (absolute risk difference taking into account center effect, -7% [95% CI, -17% to 3%]; P = .15). Predefined subgroup analyses found no interaction with ejection fraction less than 30%, type of surgery, and preoperative use of β-blockers, intra-aortic balloon pump, or catecholamines. The prevalence of hypotension (57% vs 48%), atrial fibrillation (50% vs 40%), and other adverse events did not significantly differ between levosimendan and placebo.

    Full Text Available Sam J Lehman, Derek P ChewDepartment of Medicine, Flinders University, South Australia, AustraliaAbstract: Bivalirudin is a member of the direct thrombin inhibitor group of anticoagulants. It has been evaluated as an alternative to unfractionated and low-molecular-weight heparins in the settings of percutaneous coronary intervention (PCI and acute coronary syndrome (ACS. Results of clinical trials to date suggest bivalirudin is a viable alternative to the use of a heparin combined with a glycoprotein (GP IIb/IIIa inhibitor in these settings. Thrombin has a central role in coagulation and platelet activation in ACS and during PCI. Its direct inhibition is an attractive target for therapy in these settings. Bivalirudin is a 20 amino acid polypeptide hirudin analog. It displays bivalent and reversible binding to the thrombin molecule, inhibiting its action. Direct inhibition of thrombin with bivalirudin has theoretical pharmacokinetic and pharmacodynamic advantages over the indirect anticoagulants. A reduction in rates of bleeding without loss of anti-thrombotic efficacy has been a consistent finding across multiple clinical trials. There may be economic benefits to the use of bivalirudin if it permits a lower rate of use of the GP IIb/IIIa inhibitors. This article reviews the pharmacology of bivalirudin and clinical trial evidence to date. There are now data from multiple clinical trials and meta-analyses in the setting of ACS and PCI. Early results from the acute catheterization and urgent intervention strategy (ACUITY trial are discussed.

    There has, to date, been no prospective description of the frequency with which police officers encounter individuals who display signs of excited delirium syndrome (ExDS). The ability to document the relationship between signs of excited delirium and subject outcomes and then determine the underlying pathophysiology that results in morbidity and mortality is necessary in order to determine the case definition for ExDS in live individuals. We prospectively evaluated the frequency of signs of ExDS in a cohort of consecutive subjects undergoing use of force by law enforcement officers (LEOs) and determined the frequency with which those features were encountered alone and in combination. Data were collected prospectively for all subjects undergoing use of force (UOF) by LEOs in a single police agency from August 2006 until August 2009. Ten previously published signs of ExDS were prospectively recorded by officers: pain tolerance, constant/near constant physical activity, not responding to police presence, superhuman strength, rapid breathing, not tiring despite heavy physical exertion, naked/inappropriately clothed, sweating profusely, hot to the touch, and attraction to/destruction of glass/reflective surfaces. UOF occurred in 1269 of 1.56 million police-public interactions (0.08%, 95% CI 0.08, 0.086). Of subjects undergoing police use of force, 1101/1269 or 86.8% (95% CI 84.8%, 88.6%) were assessed as having effects of emotional disturbance, drugs, alcohol or a combination of these comorbidities at the scene at the time of the UOF and 837/1269 or 66% (95% CI 63.3, 68.6) were violent at the time of the UOF. Excluding violence, 655/1269 (51.6% 95% CI 48.8, 54.4) had no signs of ExDS at the time of UOF and another 405/1269 (31.9% 95% CI 29.4, 34.6%)) had only one or two signs of ExDS at the time of UOF. The remaining 209/1269 (16.5%, 95% CI 14.5, 18.6) had 3 or more concomitant signs of ExDS at the time of UOF. One person died in our cohort who was experiencing 10

The priority of Chinese herbal medicines (CHMs plus conventional treatment over conventional treatment alone for acute coronary syndrome (ACS after percutaneous coronary intervention (PCI was documented in the 5C trial (chictr.org number: ChiCTR-TRC-07000021. The study was designed to evaluate the 10-year effectiveness of CHMs plus conventional treatment versus conventional treatment alone with decision-analytic model for ACS after PCI. Methods and Results. We constructed a decision-analytic Markov model to compare additional CHMs for 6 months plus conventional treatment versus conventional treatment alone for ACS patients after PCI. Sources of data came from 5C trial and published reports. Outcomes were expressed in terms of quality-adjusted life years (QALYs. Sensitivity analyses were performed to test the robustness of the model. The model predicted that over the 10-year horizon the survival probability was 77.49% in patients with CHMs plus conventional treatment versus 77.29% in patients with conventional treatment alone. In combination with conventional treatment, 6-month CHMs might be associated with a gained 0.20% survival probability and 0.111 accumulated QALYs, respectively. Conclusions. The model suggested that treatment with CHMs, as an adjunctive therapy, in combination with conventional treatment for 6 months might improve the long-term clinical outcome in ACS patients after PCI.

    Aims. To evaluate the efficacy of Chinese herbal medicines (CHMs) plus conventional treatment in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI). Methods and Results. Participants (n = 808) with ACS who underwent PCI from thirteen hospitals of mainland China were randomized into two groups: CHMs plus conventional treatment group (treatment group) or conventional treatment alone group (control group). All participants received conventional treatment, and participants in treatment group additionally received CHMs for six months. The primary endpoint was the composite of cardiac death, nonfatal recurrent MI, and ischemia-driven revascularization. Secondary endpoint was the composite of readmission for ACS, stroke, or congestive heart failure. The safety endpoint involved occurrence of major bleeding events. The incidence of primary endpoint was 2.7% in treatment group versus 6.2% in control group (HR, 0.43; 95% CI, 0.21 to 0.87; P = 0.015). The incidence of secondary endpoint was 3.5% in treatment group versus 8.7% in control group (HR, 0.39; 95% CI, 0.21 to 0.72; P = 0.002). No major bleeding events were observed in any participant. Conclusion. Treatment with CHMs plus conventional treatment further reduced the occurrence of cardiovascular events in patients with ACS after PCI without increasing risk of major bleeding.

    Although the incidence of falls and syncope increase with age, the underlying mechanisms are not fully understood, particularly in very old patients. We report diagnostic outcomes of tilt table and carotid sinus massage (TT/CSM) testing in a population of older old subjects (82% over 80 years of age) referred for TT/CSM from a falls clinic for assessment of syncope or unexplained falls. Prospective observational study between January 1, 2001 and January 1, 2005 involving 290 consecutive subjects undergoing TT/CSM testing according to European Society of Cardiology guidelines for the diagnosis and management of syncope. Combination of TT/CSM provided a positive result in 62% of subjects, and was significantly more likely to be positive in subjects over the age of 80 (68% vs 50%, p=0.001). Carotid sinus syndrome (CSS) was the most common diagnosis, and was significantly more common in subjects over 80 (48% vs 34%, p=0.022) particularly due to a higher incidence of mixed CSS (16% vs 7%, p=0.023). There was no significant difference in the diagnosis of subjects referred due to falls and those reporting syncope (p=0.93). No cardiovascular or neurological adverse events occurred. In our cohort of very elderly patients, the diagnostic accuracy of tilt testing and carotid sinus massage was high and adverse incidents absent when testing was indicated by a geriatrician experienced in the assessment of falls and syncope. We advocate the use of TT/CSM testing as part of a comprehensive falls/syncope assessment for the diagnostic evaluation of older patients presenting with unexplained falls and/or syncope in whom structured assessment has not identified a cause for their symptoms.

    The aim of the present study was to evaluate the effectiveness of the combined administration of myo-inositol and α-lipoic acid in polycystic ovary syndrome (PCOS) patients with normal body mass index (BMI), who had previously undergone intracytoplasmic sperm injection (ICSI) and received myo-inositol alone. Thirty-six of 65 normal-weight patients affected by PCOS who did not achieve pregnancy and one patient who had a spontaneous abortion were re-enrolled and given a cycle of treatment with myo-inositol and α-lipoic acid. For all female partners of the treated couples, the endocrine-metabolic and ultrasound parameters, ovarian volume, oocyte and embryo quality, and pregnancy rates were assessed before and after three months of treatment and compared with those of previous in vitro fertilization (IVF) cycle(s). After supplementation of myo-inositol with α-lipoic acid, insulin levels, BMI and ovarian volume were significantly reduced compared with myo-inositol alone. No differences were found in the fertilization and cleavage rate or in the mean number of transferred embryos between the two different treatments, whereas the number of grade 1 embryos was significantly increased, with a significant reduction in the number of grade 2 embryos treated with myo-inositol plus α-lipoic acid. Clinical pregnancy was not significantly different with a trend for a higher percentage for of myo-inositol and α-lipoic acid compared to the myo-inositol alone group. Our preliminary data suggest that the supplementation of myo-inositol and α-lipoic acid in PCOS patients undergoing an IVF cycle can help to improve their reproductive outcome and also their metabolic profiles, opening potential for their use in long-term prevention of PCOS.

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

    2012-01-01

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

    Full Text Available Aim: to evaluate the effectiveness of short-term PTNS for non-neurogenic OAB in adults systematically by comparing with sham procedure and other treatments. Methods: we performed a systematic review of cohort study. Data sources were MEDLINE, EMBASE, CINAHL, National Library for Health, Cochrane, and google scholar from 2005 through 2015. Meta-analysis was performed using the random effects model. Heterogeneity of effects was assessed by calculating I2 statistic. Statistical analysis was performed using Review Manager 5.3 for RCT meta-analysis. Results: we analized 11 randomised controlled trial (RCT and five prospective non-comparative studies with variable success rate. Based on percentage of responders, the results were 37.3% - 81.8% in PTNS group, 0% - 20.9% in sham group, 54.8% in anti-muscarinic group, and 89.7% in multimodal group. The decrease of voiding symptoms episodes per day was found in PTNS (0.7-4.5, sham (0.3-1.5, and anti-muscarinic (0.6-2.9 groups. In meta-analysis of four RCTs, the results favour PTNS over sham procedure with overall risk ratio of 7.32(95% CI of 1.69-32.16, p=0.09, I2=54%. Conclusion: there is an evidence of effectiveness of short term PTNS in treatment of non-neurogenic OAB. PTNS is proven significantly better than sham procedure. Key words: overactive bladder, percutaneous tibial nerve stimulation, sham, anti-muscarinic, voiding symptoms.

    2012-06-01

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

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

    This study sought to assess device-specific outcomes after implantation of bare-metal stents (BMS), zotarolimus-eluting Endeavor Sprint stents (ZES-S), paclitaxel-eluting stents (PES), or everolimus-eluting stents (EES) (Medtronic Cardiovascular, Santa Rosa, California) in all-comer patients undergoing percutaneous coronary intervention. Few studies have directly compared second-generation drug-eluting stents with each other or with BMS. We randomized 2,013 patients to BMS, ZES-S, PES, or EES implantation. At 30 days, each stent group received up to 6 or 24 months of clopidogrel therapy. The key efficacy endpoint was the 2-year major adverse cardiac event (MACE) including any death, myocardial infarction, or target vessel revascularization, whereas the cumulative rate of definite or probable stent thrombosis (ST) was the key safety endpoint. Clinical follow-up at 2 years was complete for 99.7% of patients. The MACE rate was lowest in EES (19.2%; 95% confidence interval [CI]: 16.0 to 22.8), highest in BMS (32.1%; 95% CI: 28.1 to 36.3), and intermediate in PES (26.2%; 95% CI: 22.5 to 30.2) and ZES-S (27.8%; 95% CI: 24.1 to 31.9) groups (chi-square test = 18.9, p = 0.00029). The 2-year incidence of ST in the EES group (1%; 95% CI: 0.4 to 2.2) was similar to that in the ZES-S group (1.4%; 95% CI: 0.7 to 2.8), whereas it was lower compared with the PES (4.6%, 95% CI: 3.1 to 6.8) and BMS (3.6%; 95% CI: 2.4 to 5.6) groups (chi-square = 16.9; p = 0.0001). Our study shows that cumulative MACE rate, encompassing both safety and efficacy endpoints, was lowest for EES, highest for BMS, and intermediate for PES and ZES-S groups. EES outperformed BMS also with respect to the safety endpoints with regard to definite or probable and definite, probable, or possible ST.

    Chronic kidney disease (CKD) is a powerful predictor of major cardiovascular events and stent thrombosis (ST) in patients undergoing percutaneous coronary interventions (PCI). No randomized data are available to compare, and guide the selection of type of stent between bare metal (BMS) or drug eluting stent (DES) in this population. We performed a post-hoc analysis of the PROlonging Dual antiplatelet treatment after Grading stent-induced Intimal hyperplasia studY (PRODIGY) trial, in which stable or unstable patients with coronary artery disease undergoing PCI were randomized 1:1:1:1 to receive BMS, paclitaxel- (PES), zotarolimus- (ZES-S), or everolimus- (EES) eluting stent. A total of 2003 patients were randomized, and 22 patients were excluded for missing serum creatinine leading to a final population of 1981 patients. Primary outcome was definite or probable ST. We also assessed MACE (myocardial infarction, stroke, or death), and all-cause death, as secondary outcome. CKD, defined with estimated glomerular filtration rate <60ml/min/1.73m(2), was found in 373 patients (18.8%). The incidence of ST at 2years was 5.1% in CKD and 2.1% in non-CKD patients (HR 2.57, 95% confidence interval (CI) 1.46 to 4.52, p<0.001). At multivariable regression we found that patients randomized to EES or ZES-S, but not PES, had lower risk of ST at two years as compared with BMS: adjusted HR=0.288, 95% CI [0.107-0.778, p=0.014] and HR=0.394, 95% CI [0.164-0.947, p=0.037] respectively. The number of patients needed to be treated to prevent 1 ST with an EES vs BMS was 20 in CKD and 50 in patients without CKD. EES patients had the lowest incident MACE events 26.4% as compared to BMS 35.1%, ZES-S 33.0%, or PES 35.7% patients, p=0.551. All-cause death was lowest in ZES-S group 10.6% as compared to BMS 18.1%, PES 25.5% and EES 14.9%, p=0.040. We found no significant interaction between DAPT duration (6 vs 24months) and stent type on primary outcome, PINT=0.47 for BMS, PINT=0.57 for PES, PINT

    To assess the additional effect of sudden visceral fat reduction by omentectomy on metabolic syndrome, acute-phase reactants, and inflammatory mediators in patients with grade III obesity (G-III O) undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB). Twenty-two patients were randomized into two groups, LRYGB alone or with omentectomy. Levels of interleukin-6, C-reactive protein, tumor necrosis factor-alpha, leptin, adiponectin, glucose, total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides, as well as clinical characteristics, were evaluated before surgery and at 1, 3, 6, and 12 months after surgery. Results were compared between groups. Baseline characteristics were comparable in both groups. Mean operative time was significantly higher in the group of patients who underwent omentectomy (P acute-phase reactants, and inflammatory mediators. Omentectomy does not have an ancillary short-term significant impact on the components of metabolic syndrome and does not induce important changes in the inflammatory mediators in patients undergoing LRYGB. Operative time is more prolonged when omentectomy is performed.

    1998-01-01

    Percutaneous endoscopic gastrostomy is an increasingly utilized method of enteral nutrition in patients who for a variety of reasons, are unable to swallow or possess a high risk of aspiration. This method has replaced both surgical gastrostomy and the prolonged used of nasogastric tubes since its creation, in 1980. The most frequent indications are severe neurological diseases such as cerebrovascular accidents, Parkinson's, multiple sclerosis and other processes such as severe trauma, multi-infarct dementia or diverse head and neck tumors. The procedure involves the performance of an upper endoscopy in the usual manner, followed by an insertion of a plastic catheter percutaneously in the area of maximum contact between the gastric and abdominal walls, under direct endoscopic view. Then, a guidewire is introduced through the lumen of the catheter and is enlaced by a polypectomy snare passed through the working channel of the endoscope, utilizing the guidewire to tie the distal portion of the feeding tube, which will be pulled to its final position. The complications associated to this procedure are minimal, most of them related to the endoscopy itself, like reactions to sedation, aspiration of oropharyngeal secretions, etc. There is also a possibility of local infection at the insertion site, perforation of the colon and excessive leaking of gastric contents around the tube, and for these reasons the procedure should only be performed by trained physicians, familiarized with the management of these events. The goal of this review is to illustrate the reader about the indications, contral indications, complications and general considerations in the patients who will have a percutaneous endoscopic gastrostomy.

    2010-12-01

    To assess the safety and feasibility of ambulatory percutaneous nephrolithotomy (PCNL). PCNL is the gold standard for the management of large renal stones. Although tubeless PCNL has been previously described, no case series have been published of ambulatory PCNL. The criteria for ambulatory PCNL were: single tract, stone-free status documented by flexible nephroscopy, adequate pain control, and satisfactory postoperative hematocrit level and chest radiographic findings. Patient information, including operating room and fluoroscopy times, stone size and Hounsfield units, and number of needle punctures, were collected prospectively. The time spent in the recovery room, in addition to the amount of narcotics used in the recovery room and at home, was documented. Of 10 patients, 8 had nephrostomy tracts established intraoperatively by the urologist and 2 had preoperative nephrostomy tubes placed. The median operating and fluoroscopy time was 83.5 and 4.45 minutes, respectively. The median stone diameter was 20 mm (800 Hounsfield units) in addition to a patient with a staghorn calculus. The patients spent a median of 240 minutes in the recovery room and had received a median of 19.25 mg of morphine equivalents. Only 3 patients (30%) used narcotics at home. No intraoperative complications occurred, and none of the patients required transfusions. Two postoperative complications developed: a deep vein thrombosis requiring outpatient anticoagulation and multiresistant Escherichia coli infection requiring intravenous antibiotics. In highly selected patients, ambulatory PCNL is safe and feasible. More patients are needed to verify the criteria for patients undergoing the ambulatory approach. Copyright © 2010 Elsevier Inc.

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

    To determine the triggers of blood transfusion in patients undergoing percutaneous nephrolithotomy (PCNL). The percutaneous surgery database was retrospectively reviewed to identify patients with postoperative haemorrhage and need for blood transfusion. Blood loss was estimated by the postoperative drop in haemoglobin factored by the quantity of any blood transfusion. Various patients and procedure-related factors were assessed for association with total blood loss or blood transfusion requirement using stepwise univariate, forward multivariate regression analysis. A total of 326 procedures were performed in 316 patients. Two hundred and thirty two procedures were included in the study. There were 167 males and 65 females. The mean age was 41+14 years. The mean haemoglobin drop was 1.68 +1.3 gm/dL. The overall blood transfusion rate was 14.2%. Stepwise multivariate regression analysis showed that female gender (p = 0.003), staghorn stone (p = 0.023), stone fragmentation with ultrasound (p = 0.054) and chronic renal failure (p = 0.001) were significantly predictive of the need for blood transfusion. Chronic renal failure, female gender, presence of staghorn calculi and stone fragmentation using ultrasonic device were predictive of blood transfusion in this cohort of patients. (author)

    Carpal tunnel syndrome is a compression neuropathy of the median nerve at the wrist; its symptoms include neuropathic pain and sensory and motor disturbance distributed by the median nerve. Carpal tunnel syndrome and hypercholesterolemia have similar backgrounds, but the effect of these similarities on postoperative outcomes has not been reported. Using multivariate analysis, the authors analyzed the relationship between prognostic factors, including the presence of hypercholesterolemia, and subjective postoperative outcomes of patients with idiopathic carpal tunnel syndrome. Of 168 hands with carpal tunnel syndrome that were treated surgically, 141 that were followed up and assessed 1 year postoperatively or thereafter were included. The mean postoperative follow-up period was 40.8 months. Surgery was performed through a small palmar skin incision under local anesthesia. The outcomes were postoperative symptoms, including pain and numbness, and overall Kelly assessment. Preoperative numbness and pain resolved and alleviated in 94 of 141 hands and was diminished in 59 of 64 hands. Univariate analysis showed that postoperative numbness and Kelly assessment were significantly associated with hypercholesterolemia. Multivariate analysis showed that postoperative numbness was significantly associated with smoking and hypercholesterolemia, and Kelly assessment was significantly associated with smoking (adjusted OR, 3.3; 95 percent CI, 1.1 to 10; p = 0.04) and hypercholesterolemia (adjusted OR, 2.9; 95 percent CI, 1.4 to 6.3; p = 0.01). Hypercholesterolemia, usually a systemic condition in sites other than the hand, is associated with the subjective evaluation of postoperative symptoms in patients with idiopathic carpal tunnel syndrome.

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

    Full Text Available Background: Myocardial ischemia is one of several causes of prolonged QT dispersion. The aim of this study was to evaluate the effect that percutaneous coronary intervention has on the depolarization and repolarization parameters of surface electrocardiography in patients with chronic stable angina.Methods: We assessed the effects of full revascularization in patients with chronic stable angina and single-vessel disease who underwent percutaneous coronary intervention. Twelve-lead electrocardiograms were recorded before intervention and 24 hours subsequently. We measured parameters including QRS duration, QT and corrected QT durations, and JT and corrected JT duration in both electrocardiograms and compared the values.Results: There were significant differences between the mean QRS interval (0.086 ± 0.01sec vs. 0.082 ± 0.01 second; p value = 0.01, mean corrected QT dispersion (0.080 ± 0.04 sec vs. 0.068 ± 0.04 sec; p value = 0.001, and mean corrected JT dispersion (0.074 ± 0.04 sec vs. 0.063 ± 0.04 sec; p value = 0.001 before and after percutaneous coronary intervention. No significant differences were found between the other ECG parameters.Conclusion: Our data indicate that the shortening of corrected QT dispersion and corrected JT dispersion in patients undergoing percutaneous coronary intervention is prominent.

    Saxena, Amol; Yun, Andrew

    The purpose of the present study was to describe a minimally invasive percutaneous technique for plating Weber B distal fibular fractures and to evaluate its efficacy by measuring patient outcomes and hardware removal rates. The data from 17 patients undergoing percutaneous plating of a distal fibular (Weber B) fracture were prospectively studied. A 4- to 6-hole semitubular plate with 3 screws was used for percutaneously plating. The Roles and Maudsley score was used to assess the patients' activity level. All fibular fractures had healed clinically and radiographically by 8 weeks after surgery. The postoperative Roles and Maudsley scores had improved significantly. The time required to return to activity was 4.3 ± 2.0 months. Hardware removal was required in 3 patients during the study period, which had an average of almost 4 years postoperatively. The results of the present study have demonstrated that percutaneous plating is an effective surgical option for treating Weber B distal fibular fractures.

    To present the technique of percutaneous transpedicular biopsy and debridement of discs in diagnosis and management of discitis. Fifteen patients underwent disc biopsy through a transpedicular approach with local anesthesia and fluoroscopic guidance. An attempt was made to debride the disc as much as possible. A surgical vacuum drain was deployed through the transpedicular tract when there was persistent drainage. Fifteen patients underwent percutaneous transpedicular disc biopsy and debridement of disc for suspected discitis. Three patients underwent biopsy only and 12 underwent percutaneous discectomy. Six patients had at least one positive culture. Eight patients who underwent discectomy had immediate improvement of pain or neurologic symptoms, obviating emergency surgical debridement of the disc. Four patients did not improve and underwent surgical debridement and fusion. Transpedicular biopsy of the disc is an effective technique for adequate tissue retrieval and diagnosis of discitis. Adequate debridement in selected patients with antibiotic therapy may be definitive. Epidural extension of discitis and massive vertebral destruction precludes percutaneous treatment.

    Full Text Available The surgical management of pediatric stone disease has evolved significantly over the last three decades. Prior to the introduction of shockwave lithotripsy (SWL in the 1980s, open lithotomy was the lone therapy for children with upper tract calculi. Since then, SWL has been the procedure of choice in most pediatric centers for children with large renal calculi. While other therapies such as percutaneous nephrolithotomy (PNL were also being advanced around the same time, PNL was generally seen as a suitable therapy in adults because of the concerns for damage in the developing kidney. However, recent advances in endoscopic instrumentation and renal access techniques have led to an increase in its use in the pediatric population, particularly in those children with large upper tract stones. This paper is a review of the literature focusing on the indications, techniques, results, and complications of PNL in children with renal calculi.

    Interventional radiology plays a major role in the management of bone tumors. Many different percutaneous techniques are available. Some aim to treat pain and consolidate a pathological bone (cementoplasty); others aim to ablate tumor or reduce its volume (sclerotherapy, thermal ablation). In this article, image-guided techniques of primary and secondary bone tumors with vertebroplasty, ethanol injection, radiofrequency ablation, laser photocoagulation, cryoablation, and radiofrequency ionization (coblation) will be reviewed. For each modality, the principles, the indications, and the results will be presented. The technical choice depends on the therapeutic intent-curative or palliative-and the need for consolidation, but also on the general status of the patient and the other therapeutic options. For the most complex cases, combined treatments can be required. However, the less disabling technique should always be considered first.

    Objective: To assess the implementation of Percutaneous Nephrolithotomy (PCNL) in renal stone management and evaluate the factors for efficacy and safety of PCNL. Study Design: Case series. Place and Duration of Study: Department of Urology at Jinnah Postgraduate Medical Centre, Karachi, from January 2008 to December 2011. Methodology: Patients aged above 12 years of age, irrespective of gender with normal renal function, mean stone size > 2 cm, lower pole stones > 1 cm, and ESWL failure were selected. After the procedure, on the first postoperative day, a plain abdominal radiograph was obtained to verify stone clearance. A nephrostomy tube was clamped overnight and subsequently removed when no residual stone which needs second sitting was seen. Results: In 175 patients, 62.86% (n=110) were male and the mean age was 35 A +- 9.56 years. One hundred and seventeen (66.85%) patients were primarily stone free and 13.71% (n=24) patients needed a second look procedure, thus, a total of 80.57% (n=141) patients were stone free in the same admission. Complications included failure in 4.0% (n=7) patients, bleeding in 8.57% (n=15) patients, a small residual stone in 15.43% (n=27) patients; and puncture site pain almost in every patient. Transient fever occurred in 55.43% (n=97) patients, urinary leakage in 8.57% (n=15) patients, urinary tract infections in 5.14% (n=9) patients, ureteric colic in 3.43% (n=6) patients, colonic injury in 0.57% (n=1) patient; and nephrectomy was required in 0.57% (n=1) patient due to severe bleeding. One patient (0.57%) expired due to anaesthesia complications. Conclusion: Percutaneous nephrolithotomy (PCNL) has a good success rate. There is minimal blood loss, and few major complications.

    Full Text Available Venoarterial extracorporeal membrane oxygenation (VA ECMO is widely used in patients with cardiogenic shock. Insufficient decompression of the left ventricle (LV is considered a major factor preventing adequate LV recovery. A 40-year-old male was diagnosed with acute myocardial infarction, and revascularization was performed using percutaneous stenting. However, cardiogenic shock occurred, and VA ECMO was initiated. Severe LV failure developed, and percutaneous transaortic catheter venting (TACV was incorporated into the venous circuit of VA ECMO under transthoracic echocardiography guidance. The patient was successfully weaned from VA ECMO. Percutaneous TACV is an effective, relatively noninvasive, and rapid method of LV decompression in patients undergoing VA ECMO.

    Drug dependence is one of the serious problems around the world. Saffron is one of those beneficial medicinal plants which is embedded with a similar mechanism to methadone (e.g., inhibition of serotonin reuptake). Thus, it can be helpful in reducing the withdrawal symptoms. The aim of this study was to reduce the daily dose of methadone usage and reduce its side effects using saffron in the form of medicinal supplements. This study was categorized as a clinical trial. Accordingly, 44 clients of addiction treatment centers in Sabzevar parish were randomly selected to participate in this study in 2016-2017. While the experimental group was treated with methadone syrup and self-made saffron capsules, the control group received methadone syrup and placebo capsules. The results showed that the use of saffron and methadone alleviated the symptoms of withdrawal syndrome ( paddiction. Thus, it seems rational to make use of saffron in combination with methadone in order to alleviate the symptoms of withdrawal syndrome.

    We investigated the use of a 3-hr treatment with hemodiafiltration, initiated soon after emergency or urgent coronary angiography in acute coronary syndrome (ACS) patients with associated severe renal and cardiac dysfunction. Patients with ACS and severe combined renal and cardiac dysfunction have a particularly high mortality risk. In them, the ideal strategy to both optimize treatment of coronary disease and minimize renal injury risk is currently unknown. This was an interventional study. ACS patients (STEMI and NSTEMI) with associated severe renal (eGFR ≤30 ml/min/1.73 m(2) ) and cardiac (LVEF ≤40%) dysfunction, admitted at La Spezia Hospital renal replacement therapy during hospitalization (7% vs. 27%; P = 0.04). Our pilot study suggests that, in ACS patients with severe renal and cardiac insufficiency, treatment with an aggressive prophylactic hemodiafiltration session after urgent or emergency coronary angiography seems to be associated with a relevant improvement in survival. © 2014 Wiley Periodicals, Inc.

    The association of chronic renal insufficiency with outcomes after percutaneous coronary intervention (PCI) in the current era of drug-eluting stents and modern antithrombotic therapy has not been well characterized. We queried the 2007-2011 Nationwide Inpatient Sample databases to identify all patients aged ≥18 years who underwent PCI. Multivariable logistic regression was used to compare in-hospital outcomes among patients with chronic kidney disease (CKD), patients with end-stage renal disease (ESRD), and those without CKD or ESRD. Of 3 187 404 patients who underwent PCI, 89% had no CKD/ESRD; 8.6% had CKD; and 2.4% had ESRD. Compared to patients with no CKD/ESRD, patients with CKD and patients with ESRD had higher in-hospital mortality (1.4% versus 2.7% versus 4.4%, respectively; adjusted odds ratio for CKD 1.15, 95% CI 1.12 to 1.19, Pacute coronary syndrome or stable ischemic heart disease. In patients undergoing PCI, chronic renal insufficiency is associated with higher in-hospital mortality, higher postprocedure hemorrhage, longer average length of stay, and higher average hospital charges. © 2015 The Authors.

    Full Text Available The dynamic evolution of therapeutic options including the use of vitamin K antagonists (VKA, non-vitamin K oral anticoagulants (NOAC, more potent antiplatelet drugs as well as new generation drug-eluting stents could lead to the view that the current recommendations on the management of patients with percutaneous coronary intervention (PCI requiring oral anticoagulation do not keep up with the results of several clinical studies published within the last 5 years. In the present overview, we summarize the recent advances in antithrombotic management used in atrial fibrillation patients undergoing PCI for stable coronary artery disease or acute coronary syndrome (ACS. The safety and efficacy of prasugrel and ticagrelor taken with oral anticoagulants also remain to be established in randomized trials; therefore the P2Y12 inhibitor clopidogrel on top of aspirin or without is now recommended to be used together with a VKA or NOAC. It is still unclear which dose of a NOAC in combination with antiplatelet agents and different stents should be used in this clinical setting and whether indeed NOAC are safer compared with VKA in such cardiovascular patients. Moreover, we discuss the use of anticoagulation in addition to antiplatelet therapy for secondary prevention in patients with ACS. To minimize bleeding risk in anticoagulated patients following PCI or ACS, the right agent should be prescribed to the right patient at the right dose and supported by regular clinical evaluation and laboratory testing, especially assessment of renal function when a NOAC is used.

    Hospital de Quemados del Gobierno de la Ciudad de Buenos Aires (Burn Center) is one of the reference hospitals of the Medical Radiological Emergency Response Network of Argentina. In the frame of an agreement between the Burn Center and the Nuclear Regulatory Authority of Argentina, a research project for an approach based on diagnosis and therapy of cutaneous radiation induced lesions is in progress. Individual radiosensitivity assessment was conducted in patients included in this research protocol that showed acute and/or late cutaneous reactions with grades 3 and 4 of the Toxicity criteria of the Radiation Therapy Oncology Group (RTOG) and the European organization for research and treatment of cancer (EORTC). DNA repair capacity and its kinetics were evaluated in human peripheral blood lymphocytes using alkaline comet assay and micronucleus test. In this paper, two representative cases, in which the research protocol was applied, are presented. Therapeutic response and its correlation with radiosensitivity test results are described. Case 1: female patient undergoing external radiotherapy for invasive ductal breast cancer that presented acute cutaneous radiotoxicity, grade 3 (confluent moist epithelitis, )that led to treatment break. Case 2: male patient undergoing coronary angioplasty (interventional radiology), which developed late cutaneous radiotoxicity, grade 4 (ulceration at the dorsal region). Patients were treated with: topic administration of trolamine and silver sulfadiazine with lidocaine, associated with systemic administration of pentoxiphiline and anti-oxidants. The therapeutic response was evaluated through clinical follow-up, serial photographic record and complementary tests (tele thermography and high frequency ultrasonography). Case 1 response was positive (favorable) with early local recovery and complete remission of signs and symptoms after 5 months. Both MN frequencies and comet assay showed values compatible with normal radiosensitivity

    PurposeThe purpose of this study was to determine the feasibility, safety, and early effectiveness of percutaneous image-guided ablation as second-line treatment for symptomatic soft-tissue vascular anomalies (VA).Materials and MethodsAn IRB-approved retrospective review was undertaken of all patients who underwent percutaneous image-guided ablation as second-line therapy for treatment of symptomatic soft-tissue VA during the period from 1/1/2008 to 5/20/2014. US/CT- or MRI-guided and monitored cryoablation or MRI-guided and monitored laser ablation was performed. Clinical follow-up began at one-month post-ablation.ResultsEight patients with nine torso or lower extremity VA were treated with US/CT (N = 4) or MRI-guided (N = 2) cryoablation or MRI-guided laser ablation (N = 5) for moderate to severe pain (N = 7) or diffuse bleeding secondary to hemangioma–thrombocytopenia syndrome (N = 1). The median maximal diameter was 9.0 cm (6.5–11.1 cm) and 2.5 cm (2.3–5.3 cm) for VA undergoing cryoablation and laser ablation, respectively. Seven VA were ablated in one session, one VA initially treated with MRI-guided cryoablation for severe pain was re-treated with MRI-guided laser ablation due to persistent moderate pain, and one VA was treated in a planned two-stage session due to large VA size. At an average follow-up of 19.8 months (range 2–62 months), 7 of 7 patients with painful VA reported symptomatic pain relief. There was no recurrence of bleeding at five-year post-ablation in the patient with hemangioma–thrombocytopenia syndrome. There were two minor complications and no major complications.ConclusionImage-guided percutaneous ablation is a feasible, safe, and effective second-line treatment option for symptomatic VA.

    The purpose of this study was to evaluate the efficacy and safety of percutaneous vertebroplasty for patients with symptomatic osteoporotic vertebral compression fractures adjacent to lumbar instrumented circumferential fusion. Between January 2005 and June 2010, eighteen patients in the authors' institution with lumbar instrumented circumferential fusion had adjacent symptomatic osteoporotic vertebral compression fractures. The patients received percutaneous vertebroplasty using polymethylmethacrylate bone cement augmentation. Radiographs and magnetic resonance imaging were used. The visual analog pain scale and modified Brodsky's criteria were used to compare clinical outcomes pre- and postoperatively. Minimum follow-up was 18 months. Dual-energy x-ray absorptiometry scan confirmed osteoporosis in all patients. The average interval between fusion surgery and sustaining osteoporotic vertebral compression fractures was 24.8 months. The average interval between sustaining osteoporotic vertebral compression fractures and undergoing percutaneous vertebroplasty was 49.3 days. One-level percutaneous vertebroplasty was performed in 13 patients, and 2 levels were performed in 5 patients. The patients' visual analog pain scale scores improved by an average of 53 points postoperatively. Fifteen patients returned to preinjury activities of daily living. The average restoration of the fractured vertebral body height was 12.1%. No major surgery-related complications, occurred except asymptomatic cement leakage in 3 patients. Elderly patients undergoing lumbar instrumented fusion surgery should be aware of the possibility of adjacent vertebral compression fractures. Percutaneous vertebroplasty is a minimally invasive and effective procedure to treat such adjacent segment disease. Copyright 2012, SLACK Incorporated.

    Percutaneous drainage of the bile ducts is an established procedure for malignant obstructions, in which a histological diagnosis is often not obtained. We describe the biopsy technique of obstructive lesions through biliary drainage access, using a 7F endoscopic biopsy forceps, widely available; some are even reusable. This technique applies to lesions of the hepatic ducts, of the common hepatic duct and of all extension of the common bile duct. RESUMO A drenagem percutânea das vias biliares é um procedimento estabelecido para obstruções malignas, nos quais, muitas vezes, não se consegue um diagnóstico histológico. Descrevemos a técnica de biópsia da lesão obstrutiva através do acesso de drenagem biliar, utilizando um fórcipe de biópsia endoscópica 7F, amplamente disponível e alguns reutilizáveis. Esta técnica aplica-se a lesões dos ductos hepáticos, do hepático comum e de toda extensão do colédoco.

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

    Significant advances have been achieved in the outcomes of patients with myelodysplastic syndromes (MDS) after both HLA-matched sibling donor transplants (MSDT) and non-MSDT, the latter including HLA-matched unrelated donor (MUDT) and haplo-identical donor transplants (HIDT). In this retrospective study, we analyzed the data of 85 consecutive patients with MDS who received allogeneic HSCT between Dec 2007 and Apr 2014 in our center. These patients comprised 38 (44.7%) who received MSDT, 29 (34.1%) MUDT, and 18 (21.2%) HIDT. The median overall survival (OS) was 60.2 months, the probabilities of OS being 63%, 57%, and 48%, at the first, second, and fifth year, respectively. Median OS post-transplant (OSPT) was 57.2 months, the probabilities of OSPT being 58%, 55%, and 48% at the first, second, and fifth year, respectively. The survival of patients receiving non-MSDT was superior to that of MSDT, median OSPT being 84.0 months and 23.6 months, respectively (P = 0.042); the findings for OS were similar (P = 0.028). We also found that using ATG in conditioning regimens significantly improved survival after non-MSDT, with better OS and OSPT (P = 0.016 and P = 0.025). These data suggest that using ATG in conditioning regimens may improve the survival of MDS patients after non-MSDT. PMID:28262717

    The effectiveness of sodium citrate as a prophylaxis against acid aspiration syndrome was studied in 3 groups of obstetric patients. Group I was the control group which consisted of 20 patients in established labour who were not likely to require caesarean section. No antacid had been given to these patients. Group II consisted of 20 patients who underwent elective caesarean section, while Group III consisted of another 20 patients who underwent emergency caesarean section. Group II and III were given 30ml of 0.3M sodium citrate as soon as they arrived in the operation theatre. The gastric content was aspirated after the induction of anaesthesia and at the end of surgery just before extubation. The volume was measured and a sample sent for pH analysis. Sodium citrate was found to increase the gastric pH significantly in both Group II and III patients when compared with Group I patients who underwent emergency caesarean section. We conclude that 30ml of 0.3M sodium citrate is effective in increasing gastric pH though it tends to be associated with an increase in gastric volume.

    Full Text Available Dressler Syndrome (DS is a febrile illness secondary to an inflammatory reaction involving the pleura and pericardium. It is more common in patients who have undergone surgery that involves opening the pericardium. However, DS has also been described following myocardial infarction and as an unusual complication after percutaneous procedures such as coronary stent implantation, after implantation of epicardial pacemaker leads and transvenous pacemaker leads, and following blunt trauma, stab wounds, and heart puncture. Pericardial effusions often accompany the syndrome and may develop into early or late postoperative cardiac tamponade and even recurrent cardiac tamponade. The syndrome is also characterized by pericardial or pleuritic pain, pleural effusions, pneumonitis, and abnormal ECG and radiography findings.

    Full Text Available Introduction and objectives: Rotational coronary angiography (RCA requires less contrast to be administered and can prevent the onset of contrast-induced nephropathy (CIN during invasive coronary procedures. The aim of the study is to evaluate the impact of RCA on CIN (increase in serum creatinine ≥0.5 mg/dL or ≥25% after an acute coronary syndrome. Methods: From April to September 2016, patients suffering acute coronary syndromes who underwent diagnostic coronary angiography, with the possibility of ad hoc coronary angioplasty, were prospectively enrolled. At the operator's discretion, patients underwent RCA or conventional coronary angiography (CCA. CIN (primary endpoint, as well as analytical, angiographic and clinical endpoints, were compared between groups. Results: Of the 235 patients enrolled, 116 patients received RCA and 119 patients received CCA. The RCA group was composed of older patients (64.0 ± 11.8 years vs. 59.7 ± 12.1 years; p = 0.006, a higher proportion of women (44.8 vs. 17.6%; p < 0.001, patients with a lower estimated glomerular filtration rate (76 ± 25 vs. 86 ± 27 ml/min/1.73 m2; p = 0.001, and patients who underwent fewer coronary angioplasties (p < 0.001 compared with the CCA group. Furthermore, the RCA group, received less contrast (113 ± 92 vs. 169 ± 103 ml; p < 0.001, including in diagnostic procedures (54 ± 24 vs. 85 ± 56 ml; p < 0.001 and diagnostic-therapeutic procedures (174 ± 64 vs. 205 ± 98 ml; p = 0.049 compared with the CCA group. The RCA group presented less CIN (4.3 vs. 22.7%; p < 0.001 compared to the CCA group, and this finding was maintained in the regression analysis (Adjusted relative risk: 0.868; 95% CI: 0.794–0.949; p = 0.002. There were no differences in clinical endpoints between the groups. Conclusions: RCA was associated

    Full Text Available Background: The purpose of this study was to compare the three different strategies, intravenous (IV hydroxylethyl starch (HES, IV human albumin (HA, and oral Cabergoline (Cb in the prevention of ovarian hyperstimulation syndrome (OHSS. Materials and Methods: In this prospective randomized clinical trial, 91 women at high risk of developing OHSS were allocated into the three groups, group one received 2 vial (2 × 50 ml IV HAs, in group two, 1000 ml of 6% HES was administered IV, both groups 30 min after oocyte retrieval within 4 h. Group three, 31 infertile patients received oral Cb 0.5 mg daily for 7 days after oocyte retrieval. Patients were visited 14 ± 1 days after in-vitro fertilization and if β-human chorionic gonadotropin level >10, transvaginal ultrasonography was performed 2 weeks later to confirm intrauterine pregnancy. Patients were followed up weekly for 3 months for signs of OHSS and were also informed about the signs of OHSS and asked to contact immediately if any symptoms of were detected. Results: None of the participants in group HES developed severe OHSS and only 3 patients (10% developed mild to moderate OHSS. The incident of severe OHSS was significantly higher in albumin group compared to Cb and HES group (P = 0.033 and P < 0.001, respectively. Also, the probability of developing severe OHSS was higher in Cb group than group HES (P = 0.031. Conclusion: The findings from this study suggest that administration of 1000 ml of HES 6% has a higher prophylactic effect compared to administration of IV HA and oral Cb.

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

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

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

    2003-01-01

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

After the second procedure complete or satisfactory pain relief was reported in all patients. There were no complications in four patients. One patient developed transient motor deficit after the first procedure. Other complications (nausea/vomiting, headache, ipsilateral neck pain, postcordotomy dysesthesia) were mild and transient. CONCLUSION: CT-guided percutaneous cordotomy is a useful procedure for the treatment of severe unilateral cancer pain syndromes. The procedure can be repeated on the other side at least 1 week later. These results show that the success on the second side appears to be similar to the first side with low complication rate for both procedures.

    Given the recent trends in growing per capita radiation dose from medical sources, there have been increasing concerns over patient radiation exposure. Patients with kidney stones undergoing percutaneous nephrolithotomy (PNL) are at particular risk for high radiation exposure. There exist several risk factors for increased radiation exposure during PNL which include high Body Mass Index, multiple access tracts, and increased stone burden. We herein review recent trends in radiation exposure, radiation exposure during PNL to both patients and urologists, and various approaches to reduce radiation exposure. We discuss incorporating the principles of As Low As reasonably Achievable (ALARA) into clinical practice and review imaging techniques such as ultrasound and air contrast to guide PNL access. Alternative surgical techniques and approaches to reducing radiation exposure, including retrograde intra-renal surgery, retrograde nephrostomy, endoscopic-guided PNL, and minimally invasive PNL, are also highlighted. It is important for urologists to be aware of these concepts and techniques when treating stone patients with PNL. The discussions outlined will assist urologists in providing patient counseling and high quality of care.

    To present our experience in patients with spina bifida with severe spinal abnormality undergoing percutaneous nephrolithotomy (PCNL) for large stone burden. A retrospective review identified five spina bifida patients with abnormal spinal curvature who had a PCNL for large kidney stones. The mean age was 28 years. In two patients, stones were on the concave side of the scoliotic spine further limiting percutaneous access. Mean stone burden was 940 mm2. All patients were paraplegic, three patients had symptomatic stone disease. We performed initial percutaneous renal access in radiology department and staged nephrolithotomy in operating room. Tract dilatation was accomplished using Amplatz dilators and a 24 Ch or 26 Ch nephroscope was used. Fragmentation and stone removal were accomplished in all patients using pneumatic and or ultrasound lithotripter and a retrieval grasper. No anaesthetic complications were recorded. One patient required multiple percutaneous tracts, four had single tract to access stones. Three patients were stone free after PCNL. One required second PCNL through the same tract and another patient had multiple adjunctive ESWL. All five patients were stone clear after the final procedure. Two patients required blood transfusion. No patient had major complication or admission to intensive care unit. Percutaneous nephrolithotomy in patients with spina bifida is challenging but safe. Detailed pre-operative anaesthetic assessment and precise uroradiological evaluation of renal anatomy is essential. Second-look PCNL and additional ESWL/URS treatment may be required to completely clear stones.

    Rashid, Ashraf O.

    2017-01-01

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

  6. Percutaneous cryoablation for hepatocellular carcinoma

    2016-12-01

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

    Objective To estimate the risk of death or severe harm due to bone cement implantation syndrome (BCIS) among patients undergoing hip hemiarthroplasty for fractured neck of femur. Setting Hospitals providing secondary and tertiary care throughout the National Health Service (NHS) in England and Wales. Participants Cases reported to the National Reporting and Learning System (NRLS) in which the reporter clearly describes severe acute patient deterioration associated with cement use in hip hemiarthroplasty for fractured neck of femur (assessed independently by two reviewers). Outcome measures Primary—number of reported deaths, cardiac arrests and periarrests per year. Secondary—timing of deterioration and outcome in relation to cement insertion. Results Between 2005 and 2012, the NRLS received 62 reports that clearly describe death or severe harm associated with the use of cement in hip hemiarthroplasty for fractured neck of femur. There was one such incident for every 2900 hemiarthroplasties for fractured neck of femur during the period. Of the 62 reports, 41 patients died, 14 were resuscitated from cardiac arrest and 7 from periarrest. Most reports (55/62, 89%) describe acute deterioration occurring during or within a few minutes of cement insertion. The vast majority of deaths (33/41, 80%) occurred on the operating table. Conclusions These reports provide narrative evidence from England and Wales that cement use in hip hemiarthroplasty for fractured neck of femur is associated with instances of perioperative death or severe harm consistent with BCIS. In 2009, the National Patient Safety Agency publicised this issue and encouraged the use of mitigation measures. Three-quarters of the deaths in this study have occurred since that alert, suggesting incomplete implementation or effectiveness of those mitigation measures. There is a need for stronger evidence that weighs the risks and benefits of cement in hip hemiarthroplasty for fractured neck of femur. PMID

Design: This is a prospective, randomized, double-blind, proof-of-concept study. Setting: This study was carried out at a tertiary care center. Material and Methods: A total of 125 patients diagnosed with PCOS defined as per the ESHRE/ASRM Rotterdam criteria (2003 undergoing IVF in antagonist protocol were randomized into two groups. Group A: single dose of GnRHa 0.2 mg, 35 h prior to oocyte retrieval, and Group B: 0.2 mg GnRHa 35 h prior to oocyte retrieval + repeat dose of 0.1 mg 12 h following the 1st dose. 12 h post-trigger, luteinizing hormone (LH, progesterone (P4, and follicle-stimulating hormone (FSH values were estimated. Statistical Analysis: Continuous variables were expressed as mean ± standard deviation and categorical variables as proportions where applicable. Independent sample t-test was used for continuous variables which were normally distributed and Mann–Whitney U-test for data not normally distributed. Chi-square test or Fisher's exact test was used for categorical variables where appropriate. Odds ratio (OR with 95% confidence intervals (CIs was calculated. In addition, receiver operating characteristic curve was used to evaluate the post-trigger LH, P4, and FSH values at 12 h as predictors of oocyte maturity. Main Outcome Measures: Primary outcome: maturity rate of the oocytes. Secondary outcomes: oocyte yield, fertilization rate, availability of good quality embryos on day 3, blastocyst conversion, OHSS rates, post-trigger serum LH (IU/L, FSH (IU/L, and P4 (ng/mL levels implantation rate and clinical pregnancy rate. Results: A higher number of mature (metaphase II oocytes were obtained in Group B compared to Group A (OR of 0.47; CI: 0.38–0

  11. Increased pressure within the abdominal compartment: intra-abdominal hypertension and the abdominal compartment syndrome.

    Roberts, Derek J; Ball, Chad G; Kirkpatrick, Andrew W

    2016-04-01

    This article reviews recent developments related to intra-abdominal hypertension (IAH)/abdominal compartment syndrome (ACS) and clinical practice guidelines published in 2013. IAH/ACS often develops because of the acute intestinal distress syndrome. Although the incidence of postinjury ACS is decreasing, IAH remains common and associated with significant morbidity and mortality among critically ill/injured patients. Many risk factors for IAH include those findings suggested to be indications for use of damage control surgery in trauma patients. Medical management strategies for IAH/ACS include sedation/analgesia, neuromuscular blocking and prokinetic agents, enteral decompression tubes, interventions that decrease fluid balance, and percutaneous catheter drainage. IAH/ACS may be prevented in patients undergoing laparotomy by leaving the abdomen open where appropriate. If ACS cannot be prevented with medical or surgical management strategies or treated with percutaneous catheter drainage, guidelines recommend urgent decompressive laparotomy. Use of negative pressure peritoneal therapy for temporary closure of the open abdomen may improve the systemic inflammatory response and patient-important outcomes. In the last 15 years, investigators have better clarified the pathogenesis, epidemiology, diagnosis, and appropriate prevention of IAH/ACS. Subsequent study should be aimed at understanding which treatments effectively lower intra-abdominal pressure and whether these treatments ultimately affect patient-important outcomes.

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

    A sensation of self-awareness on the relativity of our certainties comes over looking to the huge amount of data on antithrombotic therapies assessed in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). This sensation can be compared to the so-called "overview effect", a cognitive shift in awareness reported by some astronauts during spaceflight, often while viewing the Earth from orbit. In this review we will mention drugs floated like meteors in the Universe of STEMI treatment and we will discuss the body of evidence on oral and intravenous antithrombotic therapies for patients undergoing pPCI.

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

    2006-01-01

    As the number of critically ill patients requiring tracheotomy for prolonged ventilation has increased, the demand for a procedural alternative to the surgical tracheostomy (ST) has also emerged. Since its introduction, percutaneous dilatational tracheostomies (PDT) have gained increasing popularity. The most commonly cited advantages are the ease of the familiar technique and the ability to perform the procedure at the bedside. It is now considered a viable alternative to (ST) in the intensive care unit. Evaluation of PDT procedural modifications will require evaluation in randomized clinical trials. Regardless of the PDT technique, meticulous preoperative and postoperative management are necessary to maintain the excellent safety record of PDT. PMID:16356203

    Full Text Available The continuous innovations in technology, instrumentations, and techniques allow urologists to perform percutaneous nephrolithotomy (PCNL with increasing efficacy. Although recent advances have facilitated the procedure, some steps are still challenging. A thorough review of the recent urologic literature was performed to identify these improvements in PCNL technique. The newer developments mainly focused on multimodal imaging techniques, miniaturisation of instruments, tracking and navigation systems during access to the stone, and robotic systems. Further studies are necessary to better define the benefits of these new fruitful developments which remain an active research field.

    The authors performed percutaneous drainage of lung abscesses in 12 patients. Indications for drainage were septicemia and persistence or worsening of radiographic findings. These lung abscesses were refractory to intravenous antibiotics and to bronchial toilet. Etiology of the abscesses included pneumonia (most frequently), trauma, postoperative development, infected necrotic neoplasm, and infected sequestration. Guidelines for drainage included passage of the catheter through contiguously abnormal lung and pleura, inability of the patient to cough, and/or bronchial obstruction precluding bronchial drainage. Cure was achieved in 11 of 12 patients. Catheters were removed on an average of 16 days after insertion. Antibiotics were administered an average of 18 days before drainage. No major complications occurred

    Percutaneous endoscopic gastrostomy tube feeding is a safe and effective method of providing long-term enteral nutrition in patients who are unable to swallow and offers important advantages over nasogastric tub feeding. The indications of this procedure have been received and over 7 years of practice on 103 patients and 128 procedures have been experienced with Ponsky pull techniques. All patients were given vitamin K and a prophylactic antibiotic (chephalotine) prior to testing. 1.56% of major deadly complications have been reports both for reflux and aspiration at 48 and 72 hours post treatment. The most common minor complication was wound infection in 8.9% of patients. There was no further mortality during testing or while undergoing treatment in the following 30 days. All patients were suffering from post heart attack dementia and stroke (CVA) at a rate of 23.3% and 21.4%, respectively. Percutaneous endoscopic gastrostomy has become the method of choice to sustain long-term enteral nutrition.

    Full Text Available We describe the unexpected case of a 70-year-old man, with medical history of ischemic heart disease and surgery for aneurysm of abdominal aorta, who comes to the emergency department complaining of low-back pain without other symptoms or signs of organic failure. After a few hours we see a deterioration of physical conditions with pulmonary oedema, increase of blood pressure, changing in the ECG pattern, and worsening of left ventricular function with progressive increase of biomarkers for myocardial necrosis. So this pain has revealed the premature symptom of an acute coronary syndrome (ACS. After a short time a subsequent cardiac arrest complicates the clinical situation. After resuscitation, the patient undergoes successfully to coronary angiography and performed a percutaneous transluminal coronary angioplasty (PTCA.

    2011-01-01

    Aim: To assess patient outcome in a consecutive series of patients with myeloma and spinal metastases who underwent percutaneous vertebroplasty. Materials and methods: Data were gathered prospectively on all patients undergoing percutaneous vertebroplasty between June 2001 and June 2010. Outcome measures included visual analogue pain scores (VAS) and Roland–Morris Questionnaire (RMQ) in patients treated since 2005 as well as complications and long-term outcome in all patients. Results: One hundred and twenty-eight patients underwent percutaneous vertebroplasty for myeloma (n = 41) or spinal metastases (n = 87) over a 9 year period. VAS scores fell from 7.75 ± 1.88 pre-vertebroplasty to 4.77 ± 2.69 post-vertebroplasty (p = 0.001). RDQ scores improved from 18.55 ± 4.79 to 13.5 ± 6.96 (p = 0.001). Complications were recorded in three patients: cement extension to vena cava (n = 1), local haematoma (n = 1), and loss of sensation over T1 dermatome (n = 1). The Kaplan–Meier estimate of 5 year survival post-vertebroplasty was 40% for patients with myeloma and 25% for those with metastases. Conclusion: This large prospective study demonstrates percutaneous vertebroplasty reduces pain and improves disability in patients from intractable pain from myeloma or spinal metastases and now forms an important part of the multimodality treatment for these patients.

    Percutaneous techniques have increasingly gained popularity in recent years. The application of technological innovation, including neuromonitoring techniques, has the potential to increase the safety and efficacy of these procedures. Thirty patients suffering from osteoporotic dorsolumbar burst fracture were prospectively enrolled in this study. The patients underwent percutaneous fenestrated pedicle screw fixation augmented with polymethylmethacrylate (PMMA) injection. A novel surgeon-dedicated neuromonitoring device was used in order to increase the safety and the accuracy of the screw insertion. A second group of 30 patients who did not undergo neuromonitoring during percutaneous pedicle screw placement, matched for demographic characteristics, constituted the control group. A total of 296 screws were inserted. All treated patients had a good outcome, documented by an improvement in visual analogue scale (VAS) scores. Excellent trajectories were achieved in all patients. Cobb's angle and anterior vertebral height were satisfactorily restored in all study group patients. Three misplaced screws in three patients and a case of PMMA leakage without neurological deficits were observed in the control group, whereas no complication was recorded in the study group (p = 0.03). Neuromonitoring in cement-augmented percutaneous pedicle screw placement appears to improve surgeon confidence during surgery, reducing the risk of screw misplacement or cement leakage.

    Purpose: To evaluate the feasibility, safety, and clinical benefits of percutaneous laser ablation (PLA) in patients with unresectable primary and metastatic adrenocortical carcinoma (ACC). Patients and methods: Four patients with hepatic metastases from ACC and a Cushing's syndrome underwent ultrasound-guided PLA. In one case the procedure was performed also on the primary tumor. Results: After three sessions of PLA, the primary tumor of 15 cm was ablated by 75%. After 1-4 (median 1) sessions of PLA, five liver metastases ranging from 2 to 5 cm were completely ablated, while the sixth tumor of 12 cm was ablated by 75%. There were no major complications. Treatment resulted in an improvement of performance status and a reduction of the daily dosage of mitotane in all patients. The three patients with liver metastases presented a marked decrease of 24-h urine cortisol levels, an improved control of hypertension and a mean weight loss of 2.8 kg. After a median follow-up after PLA of 27.0 months (range, 9-48 months), two patients have died of tumor progression, while two other patients remain alive and free of disease. Conclusions: Percutaneous laser ablation is a feasible, safe and well tolerated procedure for the palliative treatment of unresectable primary and metastatic ACC. Further study is required to evaluate the impact of PLA on survival.

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

    Full Text Available Background: Percutaneous tracheostomy is a routine procedure in the intensive care unit (ICU. Some surgeons perform percutaneous tracheostomies using bronchoscopy believing that it increases safety. The purpose of this study was to evaluate percutaneous tracheostomy in the trauma population and to determine whether the use of a bronchoscope decreases the complication rate and improves safety. Methods: A retrospective review was completed from January 2007 to November 2010. Inclusion criteria were trauma patients undergoing percutaneous tracheostomy. Data collected included age, Abbreviated Injury Score by region, Injury Severity Score, ventilator days, and outcomes. Complications were classified as early (occurring within 24 h after the procedure. Results: During the study period, 9,663 trauma patients were admitted, with 1,587 undergoing intubation and admission to the ICU. Tracheostomies were performed in 266 patients and 243 of these were percutaneous; 78 (32% were performed with the bronchoscope (Bronch and 168 (68% without bronchoscope (No Bronch. There were no differences between the groups in Abbreviated Injury Score by region, Injury Severity Score, probability of survival, ventilator days, and length of ICU or overall hospital stay. There were 16 complications, 5 (Bronch and 11 (No Bronch. Early complications were primarily bleeding (Bronch 3% vs. No Bronch 4%, not statistically significant. Late complications included tracheomalacia, tracheal granulation tissue, bleeding, and stenosis; Bronch 4% versus No Bronch 3%, (not statistically significant. One major complication occurred, with loss of airway and cardiac arrest, in the bronchoscopy group. Conclusion: Percutaneous tracheostomy was safely and effectively performed by an experienced surgical team both with and without bronchoscopic guidance with no difference in the complication rates. This study suggests that the use of bronchoscopic guidance during tracheostomy is not routinely

    1999-10-01

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

    This paper examines the feasibility of using Holmium: yttrium-aluminum-garnet (YAG) laser to permanently obliterate the cystic duct and then using chemical sclerosants to ablate the gallbladder mucosa. Percutaneous cholecystostomy was performed in 30 domestic pigs. The cystic duct was cannulated and while the laser fiber was withdrawn at a rate of 0.5 cm/sec, pulsed laser energy (10 Hz) was delivered. Animals were sacrificed immediately (n = 7), at 72 hours (n = 4), and 6 weeks (n = 19). In the 6-week group, gallbladder sclerosis (95% alcohol plus sodium tetradecyl sulfate) was performed in 13 animals immediately after occluding the cystic duct. Control animals were included in each group

    The introduction of drug-eluting stents and advances in catheter techniques have led to increasing acceptance of percutaneous coronary intervention (PCI) as a viable alternative to coronary artery bypass graft (CABG) for unprotected left main disease. Current guidelines state that it is reasonable to consider unprotected left main PCI in patients with low to intermediate anatomic complexity who are at increased surgical risk. Data from randomized trials involving patients who are candidates for either treatment strategy provide novel insight into the relative safety and efficacy of PCI for this lesion subset. Herein, we review the current data comparing PCI with CABG for left main disease, summarize recent guideline recommendations, and provide an update on technical considerations that may optimize clinical outcomes in left main PCI.

    To assess the role of percutaneous catheter drainage (PCD) in the management of tuberculous ilio-psoas abscesses, twenty-two patients with 26 tuberculous ilio-psoas abscesses were subjected to PCD under real time US guidance taking help of a pre-procedure CT for planning the route of catheter insertion. Complete cure of the ilio-psoas abscesses could be achieved in 22 of 26 abscesses (84.6%). Average duration of drainage was 10 days. US/ CT follow-up ranged from 3-24 months. PCD was a failure in four abscesses (15.4%). Two patients, one with bilateral abscesses, had recurrent abscesses while one patient had an abscess associated with extensive spondylo-discitis. No significant complication was encountered in the study. PCD is a simple, safe and very effective (success rate 84.6%) alternative to surgical drainage in the management of tuberculous ilio-psoas abscesses. (author)

    Percutaneous dilation Tracheotomy (PDT) is becoming a popular alternative to surgical tracheotomy. In our hospital, we recently adopted the use of the PDT in intensive care unit patients. The objective [corrected] of this investigation is to characterize and quantify the rate of complications for PDT. A prospective study of 60 PDT performed at different intesive care units, betweem September 2002 to July 2003. The intraoperative time for PDT was 8 minutes. Complications included 6 cases of mild intraoperative hemorrhage, 1 case of moderate intraoperative hemorrhage, 4 cases of mild postoperative hemorrhage and 1 case of subcutaneous emphysema. PDT is a good alternative to surgical tracheotomy and should be added to the otolaryngologists armamentarium of surgical airway procedures.

    Pancreatic ductal adenocarcinoma is a highly aggressive tumor with an overall 5-year survival rate of less than 5%. Prognosis and treatment depend on whether the tumor is resectable or not, which mostly depends on how quickly the diagnosis is made. Chemotherapy and radiotherapy can be both used in cases of non-resectable pancreatic cancer. In cases of pancreatic neoplasm that is locally advanced, non-resectable, but non-metastatic, it is possible to apply percutaneous treatments that are able to induce tumor cytoreduction. The aim of this article will be to describe the multiple currently available treatment techniques (radiofrequency ablation, microwave ablation, cryoablation, and irreversible electroporation), their results, and their possible complications, with the aid of a literature review.

    The aim of this study was to assess (1) the incidence of patent foramen ovale (PFO) in carcinoid syndrome (CS) and (2) the feasibility of percutaneous closure procedure in selected patients with CS. One hundred eight patients were prospectively studied: 54 with CS and an age- and gender-matched control group. All patients underwent conventional and contrast echocardiography. Patients with clinical signs of dyspnea (New York Heart Association class > or =III), cyanosis, carcinoid heart disease (CHD), and severe PFO were referred for the percutaneous closure of PFO. The prevalence of PFO was 41% in patients with CS and 22% in the control group (p = 0.03) and was significantly higher in patients with CHD (59%, p = 0.009). Four patients (14% of those with CHD) were referred for the percutaneous closure of PFO, and 3 patients ultimately underwent PFO closure (using Amplatzer septal occluders). At 6-month follow-up, New York Heart Association class was improved in all patients, as well as arterial blood gas results (p = 0.04) and 6-minute walking distance (p = 0.03), but all patients presented residual right-to-left shunts. In conclusion, this prospective study demonstrates that in patients with CHD, the prevalence of PFO is high and that percutaneous closure of PFO is feasible, with a reduction in symptoms but with residual shunting.

    Full Text Available ABSTRACT Purpose To assess effectiveness and durability of Solifenacin (SS versus tibial nerve stimulation (PTNS versus combination therapy (PTNS + SS in women with overactive bladder syndrome (OAB. Materials and Methods 105 women with OAB were divided randomly into three groups of 35 patients each. In group A women received SS, in group B women underwent PTNS, in group C women underwent combination of PTNS + SS. Improvements in OAB symptoms were assessed with OABSS questionnaire; patients’ quality of life was assessed with OAB-q SF questionnaire. Evaluation of effectiveness of treatments was performed with PGI-I questionnaire. OABSS and PGI-I were also assessed monthly for ten months. Results All treatments were effective on symptoms. PTNS showed a greater effectiveness than SS, but PTNS + SS was more effective than SS and PTNS. Furthermore, PTNS + SS showed a greater duration of effectiveness than PTNS and SS. Conclusions Combination of PTNS with SS showed more effectiveness and more durability than PTNS and SS alone.

  4. Long-term outcome of successful percutaneous transluminal angioplasty of the fibular artery in diabetic foot syndrome and single-vessel calf perfusion depends on doppler wave pattern at the forefoot.

    2010-02-01

    In the diabetic foot syndrome (DFS) due to peripheral artery disease, the fibular artery is often the only vessel which can be revascularised. Because the fibular artery does not have a direct connection to the plantar arch, the clinical result of fibular artery PTA is dependent upon the extent of collateralization at the ankle. Therefore, successful PTA of the fibular artery with resulting biphasic doppler waves at the ankle can lead to either biphasic or monophasic post-occlusive doppler wave patterns at the forefoot. We evaluated prospectively the association of the forefoot doppler wave form on long-term clinical outcome in patients with DFS after successful PTA of the fibular artery. 44 patients with occluded calf vessels and DFS Wagner 2-4 underwent primary successful fibular artery PTA resulting in biphasic ankle doppler wave. According to doppler wave form at the forefoot, patients were divided into 1) a biphasic or 2) a monophasic group. Up to 45 months, we documented doppler wave forms, clinical course, restenosis, reinterventions, wound healing, major- and minor amputations. PTA resulted in a biphasic doppler wave at the forefoot in 26 (59 %), in 18 (41 %) in a monophasic wave pattern. Biphasic forefoot doppler wave was strongly correlated with longer event-free survival (35 bi- vs. 5.5 months monophasic, p = 0.0018) and complete wound healing (69 % s bi- vs. 44 % vs. monophasic p = 0.0309). Major amputations: 2 / 26 (8 %) in the biphasic and in 3 / 18 (17 %) in the monophasic group. Second revascularisation procedures were more often necessary in the monophasic group (7 / 18 (39 % vs. 2 / 26 (8 %)). After successful PTA of the fibular artery, monophasic doppler wave patterns at the forefoot denote insufficient collateralization and are associated with poor outcome. If successful fibular artery PTA results only in monophasic forefoot doppler, additional crural or pedal bypass should be strongly contemplated.

    We report a case of a 36-year-old woman at 34 weeks of gestation complicated with Marfan syndrome who underwent Bentall type aortic replacement surgery due to Stanford type A aortic dissection after undergoing caesarean section. Since this patient exhibited severe hypotension before coming to the operating room, it was very difficult to determine whether the cardiac surgery or caesarean section should be performed first. In this case, the caesarean section was performed first, followed by Bentall's surgery. Although intra-aortic balloon pumping and percutaneous cardiopulmonary support were required after weaning from the cardiopulmonary bypass, she was discharged on post-operative day (POD) 40 and the baby was discharged on POD 60, without signs of cerebral palsy. Unfortunately, this patient died on POD 57, due to heart failure. We discuss how to determine the priority of surgeries for patients who require emergency surgery for cardiovascular disease during pregnancy.

    Percutaneous endoscopic gastrostomy (PEG) can improve nutritional status and reduce the amount of time needed to feed neurologically impaired children. We evaluated the characteristics, complications, and outcomes of neurologically impaired children treated with PEG. We retrospectively reviewed the records of 32 neurologically impaired children who underwent PEG between March 2002 and August 2008 at our medical center. Forty-two PEG procedures comprising 32 PEG insertions and 10 PEG exchanges, were performed. The mean follow-up time was 12.2 (6.6) months. Mean patient age was 9.4 (4.5) years. The main indications for PEG insertion were swallowing difficulty with GI bleeding due to nasogastric tube placement and/or the presence of gastroesophageal reflux disease (GERD). The overall rate of complications was 47%, with early complications evident in 25% of patients and late complications in 22%. The late complications included one gastro-colic fistula, two cases of aggravated GERD, and four instances of wound infection. Among the 15 patients with histological evidence of GERD before PEG, 13 (87%) had less severe GERD, experienced no new aspiration events, and showed increased body weight after PEG treatment. PEG is a safe, effective, and relatively simple technique affording long-term enteral nutritional support in neurologically impaired children. Following PEG treatment, the body weight of most patients increased and the levels of vomiting, GI bleeding, and aspiration fell. We suggest that PEG with post-procedural observation be considered for enteral nutritional support of neurologically impaired children.

  8. Infective complication following percutaneous nephrolithotomy

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Percutaneous nephrolithotomy (PCNL is a minimally invasive procedure for patients with large renal and upper ureteric stones. Although it is less invasive than open surgery, infection is still the most common complication arising from this procedure and some patients develop septicemia and septic shock, resulting in increase in mortality and morbidity. The incidence of septic shock following PCNL is 1%; however, its mortality rate is as high as 66–80%. Endourologists who perform this procedure need to know how to prevent and manage this common complication. Large calculi, staghorn calculi, positive pelvic urine and stone culture, prolonged operative time, and diabetes are factors that increase the incidence of postoperative infection. Recently, several studies suggested the importance of intraoperative microbiologic evaluation of factors such as intraoperative pelvic urine and stone cultures for selection of suitable postoperative antibiotics. The selection of prophylactic antibiotics, postoperative antibiotics, and specific PCNL techniques play an important role in preventing infection following PCNL. We reviewed the general background, the factors, and role of intraoperative microbiologic evaluation in the management of post-PCNL infection.

    2009-01-01

    This is one of the first books to deal specifically with imaging in percutaneous musculoskeletal interventions. The use of different imaging modalities during these procedures is well described. In the first chapter, the basic procedures and different guidance techniques are presented and discussed. The ensuing chapters describe in exhaustive detail the abilities and uses of imaging in guiding procedures ranging from biopsy and joint injection to management of pain and tumors. These procedures are extensively documented in adults as well as in the pediatric population. The third part of the book describes the different indications for vascular interventions in musculoskeletal lesions. The final chapter focuses on ultrasound-guided interventions, as they are more common and tend to be fashionable. The book is well illustrated with carefully chosen and technically excellent images. Each of the 18 chapters is written by an expert of international repute, making this book the most current and complete treatment of the subject available. It should be of great interest to interventional radiologists and also musculoskeletal and general radiologists. (orig.)

    2017-01-01

    Background Percutaneous coronary intervention (PCI)—using a catheter to place a stent to keep blood vessels open—is increasingly used for high-risk patients who cannot undergo surgery. Cardiogenic shock (when the heart suddenly cannot pump enough blood) is associated with a high mortality rate. The percutaneous ventricular assist device can help control blood pressure and increase blood flow in these high-risk conditions. This health technology assessment examined the benefits, harms, and budget impact of the Impella percutaneous ventricular assist device in high-risk PCI and cardiogenic shock. We also analyzed cost-effectiveness of the Impella device in high-risk PCI. Methods We performed a systematic search of the literature for studies examining the effects of the Impella percutaneous ventricular assist device in high-risk PCI and cardiogenic shock, and appraised the evidence according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria, focusing on hemodynamic stability, mortality, major adverse cardiac events, bleeding, and vascular complications. We developed a Markov decision-analytical model to assess the cost- effectiveness of Impella devices versus intra-aortic balloon pumps (IABPs), calculated incremental cost-effectiveness ratios (ICERs) using a 10-year time horizon, and conducted sensitivity analyses to examine the robustness of the estimates. The economic model was conducted from the perspective of the Ontario Ministry of Health and Long-Term Care. Results Eighteen studies (one randomized controlled trial and 10 observational studies for high-risk PCI, and one randomized controlled trial and six observational studies for cardiogenic shock) were included in the clinical review. Compared with IABPs, Impella 2.5, one model of the device, improved hemodynamic parameters (GRADE low–very low) but showed no significant difference in mortality (GRADE low), major adverse cardiac events (GRADE low

Between 1985 and 2011, 7649 consecutive patients underwent PCI, and data from 69 young adults (age ≤40 years) and 4255 old adults (age ≧65 years) were analyzed. A Cox proportional hazards regression analysis was used to determine the independent predictors of a composite endpoint that included all-cause death and acute coronary syndrome (ACS) during the follow-up period. The mean age of the 69 young patients was 36.1±4.9 years, and 96% of them were men. Approximately 30% were current smokers, and their body mass index (BMI) was 26.7±5.0kg/m(2). The prevalence of diabetes and hypertension was 33% and 48%, respectively. All patients had ≥1 conventional cardiovascular risk factor. At a median follow-up of 9.8 years, the overall death rate was 5.8%, and new-onset ACS occurred in 8.7%. Current smoking was an independent predictor of the composite endpoint (hazard ratio 4.46, confidence interval 1.08-19.1, p=0.04) for young adults. Current smoking and obesity (high BMI) are the important clinical characteristics in young Japanese coronary heart disease patients who undergo PCI. The long-term prognosis in young patients is acceptable, but current smoking is a significant independent predictor of death and the recurrence of ACS in young Japanese coronary heart disease patients who are obese.

    Full Text Available For patients who are unable to meet their nutritional needs orally, enteral feeding via a percutaneous approach has become the mainstay of therapy. However, traditional enteral feeding methods, such as percutaneous endoscopic gastrostomy, may not be viable options for patients with severe gastroparesis or gastric outlet obstruction. Direct percutaneous endoscopic jejunostomy (DPEJ is an enteral access method that was first described more than 20 years ago and has gained popularity among gastroenterologists. This review discusses the indications for and contraindications to DPEJ, the procedure, the application of DPEJ in specific subsets of patients with gastrointestinal disorders, and presents a brief tabular summary of complications and success rates of DPEJ in case series published since 2000.

    Objective: To investigate the stiffness of lumbar spine after the injury caused by percutaneous diskectomy and evaluate the efficiency of percutaneous lumbar diskectomy by biomechanical study. Methods: Four fresh lumbar specimens were used to analyse load-displacement curves in the intact lumbar spine and vertical disc-injured lumbar spine. The concepts of average flexibility coefficient (f) and standardized average flexibility coefficient (fs) were also introduced. Results: The load-displacement curves showed a good stabilization effect of the intact lumbar spine and disc-injured lumbar spine in flexion, extension, right and left bending. The decrease of anti-rotation also can be detected (P<0.05). Conclusion: In biomechanical study, percutaneous lumbar diskectomy is one of the efficiency methods to treat lumbar diac hernia

  16. Percutaneous management of staghorn renal calculi

    Lee, Won Jay

    1989-01-01

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

    Full Text Available Intracranial extradural collection may cause an increase in intracranial pressure, requiring rapid emergency treatment to reduce morbidity and mortality. We described an alternative CT-guided percutaneous access for extradural collection drainage. We report a case of a patient with previous craniectomy for meningioma ressection who presented to the Emergency Department with symptoms of intracranial hypertension. Brains CT showed a extradural collection with subfalcine herniation. After multidisciplinary discussion a CT-guided percutaneous drainage through previous burr hole was performed. The patient was discharged after 36 hours of admission, without further symptoms. We describe a safe and effective alternative percutaneous access for extradural collection drainage in patients with previous burr hole.

    Preoperative and postoperative renography with 99mTechnetium-diethylene-triamine pentaacetic acid was performed on 33 patients who were free of renal scarring, infection, and obstruction and who underwent percutaneous renal stone removal. Although there was a transient decrease in renal function postoperatively in some patients, statistically significant reductions in renal function occurred only in 1 patient with an arteriovenous malformation that was embolized and in 1 patient who had a postoperative ureteropelvic junction stricture. The creation of more than one nephrostomy tract did not affect the results. In the absence of serious complications, percutaneous nephrostomy does not have a significant effect on renal function.

    The present report describes a case of percutaneous cryotherapy in a 36-year-old woman with a large and painful pectoral venous malformation. Cryoablation was performed in a single session for this 9-cm mass with 24 h hospitalisation. At 2- and 6-month follow-up, the pain had completely disappeared, and magnetic resonance imaging demonstrated a significant decrease in size. Percutaneous cryoablation shows promise as a feasible and apparently safe method for local control in patients with symptomatic venous vascular malformations.

    Full Text Available CONTEXT: Since the first percutaneous nephrostomy performed by Goodwin in 1954, technical advances in accessing the kidneys via percutaneous puncture have increased the use of this procedure and thus the complications too. Among these complications, digestive tract damage is not common. DESIGN: Case report. CASE REPORT: We report a duodenal lesion that was corrected using surgical exploration and we touch on the therapeutic options, which may be conservative or interventionist. We chose conservative treatment, which has been approached in diverse manners in the literature.

    2014-01-01

    Full Text Available Coronary artery perforation is an uncommon complication in patients with coronary heart disease undergoing percutaneous coronary intervention. However, pericardial tamponade following coronary artery perforation may be lethal, and prompt treatment is crucial in managing such patients. Balloon occlusion and the reversal of anticoagulant activity are the common methods used to prevent cardiac tamponade by reducing the amount of bleeding. Herein, we discuss the pros and cons of currently used occlusion types for coronary perforation. Optimal balloon occlusion methods should reduce the amount of bleeding and ameliorate subsequent myocardial ischemia injury, even during cardiac surgery.

    Full Text Available Purpose: Percutaneous endoscopic gastrostomy (PEG can improve nutritional status and reduce the amount of time needed to feed neurologically impaired children. We evaluated the characteristics, complications, and outcomes of neurologically impaired children treated with PEG. Methods: We retrospectively reviewed the records of 32 neurologically impaired children who underwent PEG between March 2002 and August 2008 at our medical center. Forty-two PEG procedures comprising 32 PEG insertions and 10 PEG exchanges, were performed. The mean follow-up time was 12.2 (6.6 months. Results: Mean patient age was 9.4 (4.5 years. The main indications for PEG insertion were swallowing difficulty with GI bleeding due to nasogastric tube placement and/or the presence of gastroesophageal reflux disease (GERD. The overall rate of complications was 47%, with early complications evident in 25% of patients and late complications in 22%. The late complications included one gastro-colic fistula, two cases of aggravated GERD, and four instances of wound infection. Among the 15 patients with histological evidence of GERD before PEG, 13 (87% had less severe GERD, experienced no new aspiration events, and showed increased body weight after PEG treatment. Conclusion: PEG is a safe, effective, and relatively simple technique affording long-term enteral nutritional support in neurologically impaired children. Following PEG treatment, the body weight of most patients increased and the levels of vomiting, GI bleeding, and aspiration fell. We suggest that PEG with post-procedural observation be considered for enteral nutritional support of neurologically impaired children.

    Purpose: We present our experience of utilizing peripheral nerve electrostimulation as a complementary monitoring technique during percutaneous thermal ablation procedures; and we highlight its utility and feasibility in the prevention of iatrogenic neurologic thermal injury. Methods: Peripheral motor nerve electrostimulation was performed in 12 patients undergoing percutaneous image-guided thermal ablations of spinal/pelvic lesions in close proximity to the spinal cord and nerve roots. Electrostimulation was used in addition to existing insulation (active warming/cooling with hydrodissection, passive insulation with CO{sub 2} insufflation) and temperature monitoring (thermocouples) techniques. Impending neurologic deficit was defined as a visual reduction of muscle response or need for a stronger electric current to evoke muscle contraction, compared with baseline. Results: Significant reduction of the muscle response to electrostimulation was observed in three patients during the ablation, necessitating temporary interruption, followed by injection of warm/cool saline. This resulted in complete recovery of the muscle response in two cases, while for the third patient the response did not improve and the procedure was terminated. No patient experienced postoperative motor deficit. Conclusion: Peripheral motor nerve electrostimulation is a simple, easily accessible technique allowing early detection of impending neurologic injury during percutaneous image-guided thermal ablation. It complements existing monitoring techniques and provides a functional assessment along the whole length of the nerve.

    To assess the ablative effectiveness, the oncological and cosmetic efficacy of image-guided percutaneous cryoablation in the treatment of single breast nodules with subclinical dimensions after identification with ultrasonography (US), mammography, magnetic resonance (MRI) and characterization by vacuum assisted biopsy. Fifteen women with a mean age of 73 {+-} 5 years (range 64-82 years) and lesion diameter of 8 {+-} 4 mm were undergoing cryotherapy technology with a single probe under US-guidance associated with intra-procedural lymph-node mapping and excision of the sentinel node. All the patients underwent surgical resection (lumpectomy) from 30 to 45 days after the percutaneous ablation. The iceball size generated by the cryoprobe during the procedure at minus 40 C was 16 x 41 mm. In 14 of the 15 patients was observed a complete necrosis of the cryo-ablated lesion both in post-procedural MRI follow-up and anatomo-pathological evaluation after surgical resection. In one case there was a residual disease in post-procedural MRI and postoperative histological examination, probably justified by an incorrect positioning of the probe. The percutaneous cryoablation as a ''minimally invasive'' technique can provide excellent oncological and cosmetic results on selected cases handled by experienced operators by using the tested devices.

    Full Text Available Background: percutaneous dilatational tracheostomy was invented by ciaglia in 1985. With advent of various instruments, various methods such as Fantoni, Grigges and etc, it became a widesepreadly used method of tracheostomy, especially in intensive care unit wards. In our country this was began in 2005, along with many work shops conducted by anesthesiology department of Tehran University of Medical sciences, with help of specialist from Turin University from ITALY. Case report: In this report two patients who underwent percutaneous dilatational tracheostomy are presented, and are compared with patients who had undergo surgical tracheostomy. Their long and short term complications such as bleeding, injury extents, and recovery was studied and presented. Conclusion: Tracheostomy is an opening in front of neck, in to the trachea, through which breathing is made possible. Percutaneous Dilatational Ttracheostomy (PDT is a method of tracheostomy, in which the need for surgery and transfer of patient to operation room is alleviated. Dispite various benefits, PDT has a few short term and long term drawbacks, which are cartilage fracture, injury to vital structures, perforation of posterior wall, sever bleeding displacement of tube, tracheo-esophageal fistula and trache-oinnominate fistula. Incidence of these complications are lower than surgical tracheostomy. Global reports, especialllly from countries with large scale experiences present a different statistic regarding its success as an alternative method for patients with long surveillance and under mechanical ventilation.

    To evaluate the safety and efficacy of percutaneous CT-guided cryoablation of the pudendal nerve for the treatment of refractory pudendal neuralgia. Eleven patients were selected to undergo percutaneous CT-guided cryoablation of the pudendal nerve based on established diagnostic criteria. Brief Pain Inventory questionnaires were administered prior to the procedure, during the immediate 24 h post procedure, and 45 days and 6 months following the procedure. Prior to treatment, the average level of pain on a scale from 0 (no pain) to 10 (worst pain imaginable) was 7.6, with pain described as ''burning'' (80%), ''pulling'' (37.5%), ''crushing'' (50%), ''pressure'' (84.5%), ''throbbing'' (50%), ''knife-life'' (52%), and ''other'' (60%). At 24 h, 45 days, and 6 months post-treatment, pain intensity dropped to 2.6, 3.5, and 3.1, respectively (p < 0.005). There were no procedure-related complications. CT-guided percutaneous cryoablation may represent a safe and efficacious option for selected patients with refractory pudendal neuralgia. (orig.)

    Full Text Available INTRODUCTION : Percutaneous nephrolithotomy (PCNL is the most frequently performed surgery for stone disease at our institution. Nearly 100 PCNL procedures are being performed in a year at our institution. Septicemia following PCNL can be catastrophic despite sterile preoperative urine and prophylactic antibiotics. Infected stones, obstructed kidneys , and comorbidit y have been held responsible. In this study we analyzed various culture specimens, namely Mid - stream urine (MSU, renal pelvic urine and crushed stones. MATERIALS AND METHODS : We performed a prospective clinical study in all our patients undergoing PCNL b etween January 2013 and December 2014. MSU was sent for culture and sensitivity testing (C&S one day prior to surgery. Percutaneous access into the ipsilateral pelvicaliceal system is achieved under image intensification using a fine, 14 gauge Kellet need le. Urine from the pelvicaliceal system is first aspirated and sent as pelvic urine C&S. Stone fragments are collected to be proces0sed for C&S. The data collected were divided into 3 main groups, that is MSU C&S, pelvic urine C&S and stone C&S. RESULTS : A total of 83 patients were included in the study, of this MSU C&S was positive in 9/83 (10.8% patients, Pelvic C&S in 10 /73 (13.7% patients and Stone C&S in 25/83 (30.1% patients. Out of 25 cases of stone culture positive patients 17 patients develope d Systemic Inflammatory Response Syndrome (SIRS but only 2 patients developed SIRS in MSU C & S positive patients. CONCLUSIONS: The results of our study suggest that positive stone C&S is the better predictor of potential urosepsis than MSU. Stone cultur e is available only after surgery but appears to be the best guide for antibiotic therapy in case of sepsis. So the routine collection of stone for C&S will be beneficial

    To evaluate outcome of percutaneous tension band wiring for transverse fractures of the patella. 16 men and 7 women aged 27 to 65 (mean, 40) years underwent percutaneous tension band wiring for transverse fractures of the patella with a displacement of >3 mm. Pain, operating time, mobility, functional score, and complications were evaluated. 20 patients underwent successful percutaneous tension band wiring. The remaining 3 patients in whom closed reduction failed underwent open reduction and tension band wiring. The mean operating time was 46 (range, 28-62) minutes. The mean follow-up period was 20 (range, 15-30) months. At the latest follow-up, all patients had regained full extension. The objective score was excellent in 20 patients and good in 3, whereas the subjective score was excellent in 17, good in 5, and fair in one. All patients had radiological union at week 8. One patient had patellofemoral arthritis (secondary to a postoperative articular step). Two patients developed superficial infections, which resolved after antibiotic therapy. Mean thigh muscle wasting was 0.7 (range, 0.4-1) cm. Three patients encountered hardware problems (impingement/irritation of the skin over the knee) necessitating implant removal. Percutaneous tension band wiring is a viable option for transverse fractures of the patella.

  5. Percutaneous phenol block of the upper thoracic sympathetic chain with computed tomography guidance. A new technique

    Energy Technology Data Exchange (ETDEWEB)

    Dondelinger, R.F.; Kurdziel, J.C.

    Twenty-one percutaneous neurolyses of the upper thoracic sympathetic chain were performed in 12 patients with CT guidance by a single injection of 1 to 3 ml of phenol at the level of Th3. Results were assessed after a follow-up period varying from 4 to 33 months. Three patients with hyperhidrosis had immediate and complete disappearance of symptoms, but only one patient remained dry. In 7/14 procedures done for Raynaud's disease symptoms disappeared or diminished. These long term results are competitive with surgery. Three transitory Horner syndromes and one pneumothorax occurred.

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

    The aim of this study was to assess clinical benefit of the Echo-guided ProGlide technique in patients undergoing percutaneous transfemoral transcatheter aortic valve implantation (TF-TAVI). The efficacy of the Echo-guided ProGlide technique during percutaneous TF-TAVI was not previously clarified. A total of 121 consecutive patients who underwent percutaneous TF-TAVI at our institution between February 2014 and July 2017 were enrolled in this study. According to the introduction of this novel technique in March 2016, patients were divided into two groups (echo-guided group who underwent TAVI from March 2016 to July 2017, n = 63; not echo-guided group who underwent TAVI from February 2014 to February 2016, n = 58). The incidence of major vascular complications, defined per the Valve Academic Research Consortium-2 criteria, and ProGlide complications including acute femoral artery stenosis or occlusion and bleeding requiring any intervention. The incidence of major vascular complication and ProGlide complication were significantly lower in the echo-guided group than in not echo-guided group (1.6% vs 17.2%, P guided ProGlide technique was independently associated with prevention of ProGlide complications (odds ratio, 0.11; 95% confidential interval, 0.01-0.76; P = 0.03). This novel Echo-guided ProGlide technique was associated with a lower rate of major vascular complications, particularly ProGlide complications during percutaneous TF-TAVI. © 2017, Wiley Periodicals, Inc.

  12. Injury to the anterior tibial system during percutaneous plating of a proximal tibial fracture.

    Science.gov (United States)

    Gary, Joshua L; Sciadini, Marcus F

    2012-07-01

    Minimally invasive osteosynthesis of proximal tibial fractures has grown in popularity in recent years. This article describes a patient with a Schatzker type VI proximal tibial fracture (AO/OTA type 41.C3) and previous compartment syndrome treated with definitive fixation 8 weeks after initial injury with a precontoured proximal tibial plate and a distal targeting device. Brisk bleeding occurred during percutaneous insertion of a cortical screw at the midshaft of the tibia. Surgical exploration revealed sidewall tearing of the anterior tibial artery and vein, which were clipped at the screw insertion site. After the bleeding was controlled, the patient had a strong palpable posterior tibial pulse with no palpable dorsalis pedis pulse, and the foot remained well perfused. Function of the deep peroneal nerve was normal postoperatively. Previous concerns regarding the percutaneous treatment of proximal tibial fractures have focused on the risks of damage to the superficial peroneal nerve from distal screws. Based on cadaveric studies, percutaneously and laterally based screw placement in the distal tibial metaphysis threatens injury to the anterior tibial system. However, with alterations to the normal anatomy caused by severe trauma, previously described safe zones may be changed and neurovascular structures may be exposed to risk in locations that were previously thought safe.

    Percutaneous endoscopic gastrostomy feeding provides enteral nutrition to patients with neurological dysphagia. Thirty-day mortality rates of 4-26% have been reported, with pneumonia being the common cause post-percutaneous endoscopic gastrostomy insertion. This retrospective analysis of percutaneous endoscopic gastrostomy tube insertions in Malta (January 2008 - June 2010) compares the incidence of pneumonia in patients fed through a nasogastric tube versus in those fed via a percutaneous endoscopic gastrostomy tube. We analyzed the indications, poor prognostic factors and mortality for percutaneous endoscopic gastrostomy insertion. Ninety-seven patients underwent percutaneous endoscopic gastrostomy insertion. Fifty-four patients received nasogastric feeds before percutaneous endoscopic gastrostomy feeds. Patients on nasogastric feeds developed 32 episodes of pneumonia over a total of 7884 days of feeds (1 every 246 days). Patients with percutaneous endoscopic gastrostomy feeds after a period of nasogastric feeds developed 48 pneumonia episodes over 36,238 days (1 every 755 days). Patients with percutaneous endoscopic gastrostomy feeds without previous nasogastric feeds developed 28 pneumonia episodes over 23,983 days (1 every 856 days), and this was statistically significant (χ 2 test p value nasogastric feeds. However, pneumonia is still the major cause of death among percutaneous endoscopic gastrostomy patients.

    Purpose. To determine the clinical variables associated with bacteriuria in patients undergoing primary percutaneous antegrade urinary drainage procedures in order to predict the utility of routinely obtaining urine cultures at the time of the procedure. Methods. Between October 1995 and March 1998 urine cultures were prospectively obtained in all patients undergoing a primary percutaneous antegrade urinary drainage procedure. One hundred and eighty-seven patients underwent 264 procedures. Results were available in 252 cases. Culture results were correlated with clinical, laboratory, and demographic variables. Anaerobic cultures were not uniformly performed. Results. Urine cultures were positive in 24 of 252 (9.5%) cases. An indwelling or recently removed ipsilateral device (catheter or stent) and a history of previous cystectomy with urinary diversion were significant predictors of a positive culture. Patients without either of these predictors, and without clinical or laboratory evidence of infection, were rarely found to have positive cultures. Conclusion. The likelihood of a positive urine culture can be predicted on the basis of the aforementioned clinical variables. In the absence of these clinical indicators routine urine cultures are neither useful nor cost-effective

    Total knee arthroplasty (TKA) is a common procedure resulting in significant post-operative pain. Percutaneous cryoneurolysis targeting the infrapatellar branch of the saphenous nerve and anterior femoral cutaneous nerve could relieve post-operative knee pain by temporarily blocking sensory nerve conduction. A retrospective chart review of 100 patients who underwent TKA was conducted to assess the value of adding perioperative cryoneurolysis to a multimodal pain management program. The treatment group consisted of the first 50 patients consecutively treated after the practice introduced perioperative (five days prior to surgery) cryoneurolysis as part of its standard pain management protocol. The control group consisted of the 50 patients treated before cryoneurolysis was introduced. Outcomes included hospital length of stay (LOS), post-operative opioid requirements, and patient-reported outcomes of pain and function. A significantly lower proportion of patients in the treatment group had a LOS of ≥2days compared with the control group (6% vs. 67%, ppain intensity and pain interference at two- and six-week follow-up, respectively. Perioperative cryoneurolysis in combination with multimodal pain management may significantly improve outcomes in patients undergoing TKA. Promising results from this preliminary retrospective study warrant further investigation of this novel treatment in prospective, randomized trials. III. Copyright © 2016 The Authors.

  16. Emergency bypass post percutaneous atrial ablation: a case report.

    LENUS (Irish Health Repository)

    Hargrove, M

    2010-11-01

    A 34-year-old male undergoing percutaneous atrial ablation procedure for paroxysmal fibrillation required emergency sternotomy for cardiac tamponade. The patient had been anticoagulated and had received plavix and aspirin prior to and during the ablation procedure. Seven units of red cell concentrate had been transfused in the cardiac catherisation laboratory. On arrival in theatre, the patient was hypotensive, but was awake on induction of anaesthesia. No recordable blood pressure with non-invasive monitoring was observed. A sternotomy was immediately performed and, on evacuation of the pericardium, a bleeding site was not visible. The patient was commenced on cardiopulmonary bypass. Bleeding site was identified and the defect closed. The patient was weaned from cardiopulmonary bypass with minimal inotropic support and made an uneventful recovery. Bypass time was 38 minutes. A literature review showed a 1% incidence of post-ablation bleeding(1). The incidence of reverting to bypass for such an event has not been reported previously. During these procedures, it might be wise to have the cardiothoracic team notified while atrial ablation procedures are being performed in the cardiac catheterization laboratory.

    Full Text Available Objective To share our experience in percutaneous nephrolithotomy (PCNL procedures in patients with horseshoe kidney. Materials and Methods The data of 7 patients undergoing PCNL were analyzed retrospectively. Preoperative clinical and laboratory data of patients (including complete urinalysis, complete blood count, serum biochemistry, and coagulation tests were recorded. The stone surface area (mm2 was calculated by graph paper tracing of two dimensional projection of the stone on a plain film of the kidneys, ureters and bladder (KUB in the anteroposterior view by investigators. In addition, per-operative and post-operative findings were evaluated. Success and complication rates (according to the classification of Clavien were also determined. Results The mean stone surface area was 1234 (range 250-2460 mm2 mm2. Six patients were treated through a single tract, and one patient required additional access. Access was directed to the middle calyx (n=2, superior calyx (n=4, middle and inferior calyx (n=1 through the supracostal (n=2 and subcostal (n=5 areas. Mean operative time was 131 (range 70-215 minutes minutes. Stone-free rate after single session PCNL was 71% (n=5 and increased to 86% (n=6 with a post-operative secondary ureterorenoscopy procedure. Complications including bleeding necessitating blood transfusion (Clavien grade 2 and prolonged drainage (Clavien degree 3a were occurred in only 2 patients (24%. Conclusion PCNL is a safe and successful procedure in patients with horseshoe kidney and comparable with PNL procedures in patients with normal renal anatomy

    The aim of this study was to retrospectively evaluate the results of pediatric percutaneous nephrolithotomy (PNL) cases, and discuss the results and necessity of non-contrast computerized tomography (CT) in these cases. In all, 48 pediatric patients who underwent PNL were retrospectively evaluated. Before PNL, either intravenous urography or CT was performed. In all patients, we evaluated the PNL time, scopy time with stone burden, and complications. During the PNL procedure, we switched to open surgery in two cases: in one because of renal pelvis perforation and in the other because of transcolonic access. In one patient who was scheduled to undergo PNL, we performed open surgery, primarily because we detected a retrorenal colon with CT. The stone burden in 45 patients who underwent PNL was 445 ± 225 mm(2), the PNL time was 51 ± 23 min, and the scopy time was 6.1 ± 2.7 min. We removed nephrostomy tubes 1-4 days after the procedure. In two patients, 24 h after removal of nephrostomy tubes, we inserted double J stents because of prolonged urine extravasation from the tract. In all, 34 of the 45 patients were stone-free, 5 patients had clinically insignificant stone fragments, and 6 patients had residual stones. PNL is a safe and effective method in the treatment of pediatric patients with kidney stones. Clinical experience is the most important factor in obtaining stone-free results. CT should be performed in all pediatric patients in order to prevent colon perforation.

    The original concept of percutaneous, radiological abscess drainage was confined to well circumscribed, solitary abscesses, that could be reached by a short access avoiding transgression of uninvolved organs or compartments. With increasing experience criteria for percutaneous abscess drainage have been expanded to radiological treatment of pancreatic, periappendiceal, diverticular, interloop and mediastinal abscesses and fluid collections. The authors present their experience with percutaneous treatment of such 'complicated' abscesses in 140 patients. (orig.) [de

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

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

    Regional anesthesia is commonly used in children. Our hypothesis was that percutaneous ultrasound-guided (PERC) rectus sheath blocks would result in lower postoperative pain scores compared to intraoperative (IO) rectus sheath blocks following umbilical hernia repair. A single-institution randomized blinded trial was conducted in pediatric patients undergoing elective umbilical hernia repair. The primary outcome was mean postoperative Wong-Baker pain score. Secondary outcomes included narcotic requirements and length of postoperative stay. Fifty-eight patients were included: 28 PERC and 30 IO. Operating room time was significantly longer in the PERC group (41 vs. 35min, pblocks resulted in similar mean postoperative pain scores. There were no differences in secondary outcomes such as time to first narcotic, narcotic requirements, and length of stay. The additional resources required to complete a percutaneous ultrasound-guided rectus sheath block may not be warranted. Randomized controlled trial. Level I. Copyright © 2017 Elsevier Inc.

    Currently there is no consensus regarding the use of bilateral simultaneous percutaneous surgery for Hallux valgus treatment. Although the technique described in M. Prado's book, recommends operating only one foot at a time there are no published studies confirming it. The aim of this study was to evaluate whether there is a difference between the results of patients that have been percutaneously operated on one foot and those operated on both feet at the same surgical time for mild to moderate Hallux valgus correction. We did a retrospective single centre evaluation of 93 feet (61 patients) with Hallux valgus operated percutaneously. 29 patients were operated unilaterally (group I) and 32 bilaterally simultaneously (group II) between 2005 and 2009. The Metatarsophalangeal angle (MPA), Intermetatarsal angle (IMA) and Distal metatarsal articular angle (DMAA) were evaluated pre- and postoperatively. The AOFAS score, the degree of patients' satisfaction and the complications were evaluated postoperatively. The mean follow-up was 24.0 months in group I, and 28.0 in group II. The average postoperative AOFAS score was 86.8, 82.9 in group I and 88.6 in group II (p>0.05). 90.6% were satisfied or very satisfied in group I, and 89.7% in group II (p>0.05). There was no statistically significant difference (p>0.05) in the average correction of MPA, DMAA, and IMA. The complications rate was similar in both groups. The similar results obtained in both groups suggest that the simultaneous bilateral percutaneous surgery gives equivalent results to the unilateral, which has an important socioeconomic impact since there is only one recovery time for both feet.

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

    A completely percutaneous approach to infrarenal abdominal aortic aneurysm (AAA) endografting has the theoretic benefits of being minimally invasive and more expedient. Our goal was to demonstrate the utility of this approach using a suprarenal fixation device and a suture-mediated closure system. We conducted a single-institution, retrospective review of 14 patients who underwent percutaneous AAA repair with the Zenith device between August 2003 and March 2007. Immediate and delayed access-related outcomes were examined over a mean follow-up of 12.1+/-2.0 months. Mean AAA size was 5.6 cm. Immediate arterial closure and technical success rate was 96% (27/28 vessels). One immediate hemostatic failure required open surgical repair. Over follow-up, one vessel required operative repair for new-onset claudication. No other immediate or delayed complications (thrombosis, pseudoaneurysm, infection, or deep venous thrombosis) were detected. A percutaneous approach for the treatment of AAA has several advantages over femoral artery cutdown but also has its own unique set of risks in the immediate and late postoperative period. Ultimately, the "preclose technique" can be safely applied for the Zenith device despite its large-bore delivery system.

    Objective: To discuss the method and effectiveness of percutaneous drainage for hepatic abscess under CT guidance. Methods: 20 patients were enrolled into this retrospective research, including 13 males and 7 females with age form 18 to 84 yrs. The diagnosis were made by clinical examination, laboratory test and CT imaging. Hepatic abscess focus involved right lobe in 9 cases, left lobe of 6 cases, both lobes with 5 cases. All patients received percutaneous abscess drainage subsequently. Results: There were 14 cases with solitary abscess, in which 9 disappeared completely after single procedure of aspiration under CT guidance, 1 disappeared after twice aspirations. Multiple or multi-lobular abscesses were found in six cases, which were treated by aspirating the larger one first or by splitting multi-aspiration. In all cases, drainage catheters were placed and lavage was done with a mean time of 19.2 days together with intravenous antibiotics. There was no recurrence until the end-piont of research. Conclusions: Percutaneous CT-guided aspiration and drainage is an effective way in the treatment of hepatic abscess. (authors)

    Medical clinicians are used to being consulted by patients who want to restore their youthful appearance. Although structural changes to the face and body may be achieved with surgery, for example, face lifts, the impression of youth also relies heavily on young-looking skin. It is desirable to have thicker and tighter skin to properly fulfill the desire for youth. Percutaneous collagen induction offers an antiaging effect to improve the appearance of old skin. It allows us to improve our patients' skin from the inside outward as well as from the surface. Experience has shown that percutaneous collagen induction works optimally when combined with a scientific skin care program to restore a youthful appearance. In addition, the same technique has proven to be very effective in minimizing acne scars and burn scars by removing scar collagen and replacing it with normal collagen. Consequently, scar contractures and depressed scars are improved. With the introduction of percutaneous collagen induction therapy in 1997, a simple and fast method was developed with regard to safely treating wrinkles and scars and producing lasting smoothness. As opposed to ablative laser treatments, the epidermis remains intact and is not damaged. For this reason, the operation can be safely repeated if needed, and it can be also applicable to regions where laser treatments or deep peelings cannot be done.

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

    Patients with chest pain who present to emergency departments have a significantly higher incidence of acute coronary syndrome (ACS) than patients with chest pain presenting to outpatient settings, so emergency department clinicians should have a lower threshold for considering ACS as an etiology. Evaluating patients with suspected ACS in the emergency department involves obtaining a history, physical examination, electrocardiograms (ECGs), and cardiac troponin measurements in conjunction with risk calculators. These parameters cannot be used individually because, for example, a normal ECG result does not exclude ACS and troponin levels can be elevated in many conditions. All patients with suspected ACS should receive aspirin, if not contraindicated, as soon as possible. Those with an ST-segment elevation myocardial infarction (STEMI) or those without STEMI who are in unstable condition should be triaged to undergo reperfusion therapy, typically via percutaneous coronary intervention (PCI), within 120 minutes of first medical contact. If that time limit cannot be met because the patient must be transferred to a PCI-capable facility, fibrinolytic therapy should be initiated within 30 minutes of presentation if STEMI is present. (Fibrinolytic therapy is contraindicated for myocardial infarction without STEMI.) Patients also should receive nitroglycerin to relieve angina and beta blockers if not contraindicated.

    2016-05-01

    Full Text Available Percutaneous coronary intervention (PCI improves symptoms and prognosis in ischemia-inducing, functionally significant, coronary lesions. Use of fractional flow reserve allows physicians to investigate the ischemia-inducing potential of a specific lesion and can be used to guide coronary revascularization, especially in multivessel coronary artery disease. Fractional flow reserve-guided PCI has been extensively investigated. Results show that deferral of stenting in non-significant lesions is safe, whereas deferral of stenting in functionally significant lesions worsens outcome. FFR-guided PCI improves outcome in multivessel disease over angiography-guided PCI. Until recently, there was little known about the long-term outcome of FFR-guided revascularization and its validity in acute coronary syndromes. This review aims to address the new evidence regarding long-term appropriateness of FFR-guided PCI, the need for hyperemia to evaluate functional severity, and the use of FFR in acute coronary syndromes.

    Full Text Available OBJECTIVES: To identify predictors of in-hospital mortality in patients with acute myocardial infarction undergoing pharmacoinvasive treatment. METHODS: This was an observational, prospective study that included 398 patients admitted to a tertiary center for percutaneous coronary intervention within 3 to 24 hours after thrombolysis with tenecteplase. ClinicalTrials.gov: NCT01791764 RESULTS: The overall in-hospital mortality rate was 5.8%. Compared with patients who survived, patients who died were more likely to be older, have higher rates of diabetes and chronic renal failure, have a lower left ventricular ejection fraction, and demonstrate more evidence of heart failure (Killip class III or IV. Patients who died had significantly lower rates of successful thrombolysis (39% vs. 68%; p = 0.005 and final myocardial blush grade 3 (13.0% vs. 61.9%; p<0.0001. Based on the multivariate analysis, the Global Registry of Acute Coronary Events score (odds ratio 1.05, 95% confidence interval (CI 1.02-1.09; p = 0.001, left ventricular ejection fraction (odds ratio 0.9, 95% CI 0.89-0.97; p = 0.001, and final myocardial blush grade of 0-2 (odds ratio 8.85, 95% CI 1.34-58.57; p = 0.02 were independent predictors of mortality. CONCLUSIONS: In this prospective study that evaluated patients with ST-segment elevation myocardial infarction treated by a pharmacoinvasive strategy, the in-hospital mortality rate was 5.8%. The Global Registry of Acute Coronary Events score, left ventricular ejection fraction, and myocardial blush were independent predictors of mortality in this high-risk group of acute coronary syndrome patients.

    Introduction: When the non-operative treatment of tennis elbow fails to improve the symptoms a surgical procedure can be performed. Many different techniques are available. The percutaneous release of the common extensor origin was first presented by Loose at a meeting in 1962. Despite the simplicity of the operation and its effectiveness in relieving pain with minimal scarring this procedure is still not widely accepted. This study presents the long-term results of percutaneous tennis elbow release in patients when conservative measures including local steroid injections have failed to relieve the symptoms. Patients and Methods: Percutaneous release of the extensor origin was performed in 24 consecutive patients (seven male and seventeen female), providing 30 elbows for this study. The age of the patients ranged from 26 to 71 years with mean age of 55 years. The technique involved a day case procedure in the operating theatre using local anaesthesia without the need for a tourniquet. The lateral elbow was infiltrated with 5mls 1% lignocaine and 5mls 0.5% bupivicaine with 1:200,000 adrenaline. All operations were performed by the senior author. The patients were assessed post operatively by using DASH (disabilities of arm, shoulder and hand) score and Oxford elbow scores. The mean follow up period was 36 months (1-71months). Results: Twenty one patients returned the DASH and Oxford elbow questionnaires. Four patients were lost in the follow up. The post operative outcome was good to excellent in most patients. Eighty seven percent of patients had complete pain relief. The mean post-op DASH score was 8.47 (range 0 to 42.9) and the mean Oxford elbow score was 42.8 (range 16 to 48). There were no complications reported. All the patients returned to their normal jobs, hobbies such as gardening, horse riding and playing musical instruments. Conclusion: In our experience Percutaneous release of the epicondylar muscles for humeral epicondylitis has a high rate of success

    Limited information exists on whether changes in medical practices over the study decades have affected the outcomes of acute coronary syndrome (ACS) patients who undergo early coronary artery bypass surgery (CABG) during index hospitalisation. Data on trends for early CABG referral and associated outcomes were obtained among 11,485 ACS patients enrolled in the biennial Acute Coronary Syndrome Israeli Surveys (ACSIS) 2000-2010. Among 11,485 patients, 566 (5%) were referred to early CABG. These patients displayed higher risk characteristics, including Killip class >II, anterior myocardial infarction, greater left ventricular dysfunction, and more frequent use of mechanical ventilation and intra-aortic balloon pump (all ptrend over the study decade (6.7% - 1.7%; p<0.001). One year survival was similar between patients referred to early CABG during the late (years: 2006-2010) vs. early (years: 2000-2005) period (85.7% vs. 90%; log-rank p-value=0.15), whereas, among patients who didn't undergo early CABG, and underwent percutaneous coronary intervention (PCI) or medical management only, enrolment during the late periods was associated with a significant survival benefit (91.5% vs. 88.1%; log-rank p-value<0.001). Over the study decade there was a significant decline in referral for early CABG, without a difference in the one-year mortality between the early and non-early CABG group.

    Since the spine is one of the most complex joint structures in the human body, its surgical treatment requires careful planning and high degree of precision to avoid any unwanted neurological compromises. In addition, comprehensive biomechanical analysis can be very helpful because the spine is subject to a variety of load. In case for the osteoporotic spine in which the structural integrity has been compromised, it brings out the double challenges for a surgeon both clinically and biomechanically. Thus, we have been developing an integrated medical image system that is capable of doing the both. This system is called orthopedic surgical analyzer and it combines the clinical results from image-guided examination and the biomechanical data from finite element analysis. In order to demonstrate its feasibility, this system was applied to percutaneous vertebroplasty. Percutaneous vertebroplasty is a surgical procedure that has been recently introduced for the treatment of compression fracture of the osteoporotic vertebrae. It involves puncturing vertebrae and filling with polymethylmethacrylate (PMMA). Recent studies have shown that the procedure could provide structural reinforcement for the osteoporotic vertebrae while being minimally invasive and safe with immediate pain relief. However, treatment failures due to excessive PMMA volume injection have been reported as one of complications. It is believed that control of PMMA volume is one of the most critical factors that can reduce the incidence of complications. Since the degree of the osteoporosis can influence the porosity of the cancellous bone in the vertebral body, the injection volume can be different from patient to patient. In this study, the optimal volume of PMMA injection for vertebroplasty was predicted based on the image analysis of a given patient. In addition, biomechanical effects due to the changes in PMMA volume and bone mineral density (BMD) level were investigated by constructing clinically

    Thrombosis of a prosthetic valve is a serious complication in patients with prosthetic heart valves. Thrombolysis is the initial choice of treatment. Patients who do not respond to thrombolysis are subjected to surgery which carries a high risk. We report a case series of 5 patients with prosthetic mitral valve thrombosis who did not respond to thrombolysis and were subjected to percutaneous manipulation of the prosthetic valves successfully and improved. Five patients who were diagnosed to have prosthetic mitral valve thrombosis and failed to respond to a minimum of 36 h of thrombolysis (persistent symptoms with increased gradients, abnormal findings on fluoroscopy),were subjected to percutaneous treatment after receiving proper consent. None of them had a visible thrombus on transthoracic echocardiogram. All patients underwent transseptal puncture following which a 6F JR4 guiding catheter was passed into the left atrium. The valve leaflets were repeatedly hit gently under fluoroscopic guidance till they regained their normal mobility. Mean age was 38.8 years. Average peak and mean gradients prior to the procedure were 38 and 25 and after the procedure were 12 and 6 mm of Hg respectively. All patients had successful recovery of valve motion on fluoroscopy with normalization of gradients and complete resolution of symptoms. None of the patients had any focal neurological deficits, embolic manifestations or bleeding complications. Percutaneous manipulation of prosthetic valves in selected patients with prosthetic valve thrombosis who do not respond to thrombolytic therapy is feasible and can be used as an alternative to surgery.

    2017-08-01

    Full Text Available Background The local injection of novel cardioprotective study drugs prior to percutaneous coronary intervention could cause embolisation of thrombus, resulting in increased reperfusion injury and subsequent infarct size. The aim of this study was to assess the safety of the delivery of an intracoronary therapy delivered during primary percutaneous coronary intervention for acute myocardial infarction prior to the re-establishment of thrombolysis in myocardial infarction III flow. Methods One hundred sixty-seven patients with acute myocardial infarction successfully reperfused through primary percutaneous coronary intervention and undergoing Cardiac MRI within the first week after reperfusion were studied. Patients either underwent the delivery of an intracoronary agent (IMP or placebo prior to balloon dilatation ( n  = 80 or standard primary percutaneous coronary intervention procedure ( n  = 117. Results Baseline characteristics were similar between the two groups. There were a similar number of successful procedures (IC IMP 75 (93.8% vs. No IMP 114, (97.4%, p  = 0.374, rates of no-reflow (IC IMP 1 (1.3% vs. No IMP 2 (1.7%, p  = 0.99 and levels of ST segment resolution (88.5% IC IMP vs. No IC IMP 87.0%, p  = 0.669 between the two groups. Similar levels of microvascular obstruction were seen between the two groups with a trend to reduced infarct size, and improved ejection fractions in the IMP group. Lower MACE rates were seen in the IMP group. Conclusion The local intracoronary infusion of potential cardioprotective agents prior to the restoration of TIMI flow in patients undergoing primary percutaneous coronary intervention for acute myocardial infarction appears to be safe and does not increase microvascular damage. This route should be considered when testing novel cardioprotective agents.

    Full Text Available Psychosocial stress and activation of neutrophil granulocytes are increasingly recognized as major risk factors of coronary artery disease (CAD, but the possible relationship of these two factors in CAD patients is largely unexplored. Activation of neutrophils was reported to be associated with stenting; however, the issue of neutrophil state in connection with percutaneous coronary intervention (PCI is incompletely understood from the aspect of stress and its hypothalamic-pituitary-adrenal axis (HPA background. Thus, we aimed to study cortisol- and ACTH-associated changes in granulocyte activation in patients undergoing PCI.Blood samples of 21 stable angina pectoris (SAP and 20 acute coronary syndrome (ACS patients were collected directly before (pre-PCI, after (post-PCI and on the following day of PCI (1d-PCI. Granulocyte surface L-selectin, CD15 and (neutrophil-specific lactoferrin were analysed by flow cytometry. Plasma cortisol, ACTH, and lactoferrin, IL-6 were also assayed. In both groups, pre- and post-PCI ratios of lactoferrin-bearing neutrophils were relatively high, these percentages decreased substantially next day; similarly, 1d-PCI plasma lactoferrin was about half of the post-PCI value (all p≤0.0001. Post-PCI ACTH was reduced markedly next day, especially in ACS group (SAP: p<0.01, ACS: p≤0.0001. In ACS, elevated pre-PCI cortisol decreased considerably a day after stenting (p<0.01; in pre-PCI samples, cortisol correlated with plasma lactoferrin (r∼0.5, p<0.05. In 1d-PCI samples of both groups, ACTH showed negative associations with the ratio of lactoferrin-bearing neutrophils (SAP: r = -0.601, p<0.005; ACS: r = -0.541, p<0.05 and with plasma lactoferrin (SAP: r = -0.435, p<0.05; ACS: r = -0.609, p<0.005.Pre- and post-PCI states were associated with increased percentage of activated/degranulated neutrophils indicated by elevated lactoferrin parameters, the 1d-PCI declines of which were associated with plasma

    2010-01-01

    Brachymetatarsia is not an unusual deformity and is often associated with functional and cosmetic issues that warrant surgical reconstruction. Lengthening of the affected metatarsal can be undertaken on an acute basis in a single operative procedure that involves the use of a bone graft or by means of gradual callus distraction. Because of the risk of metatarsophalangeal joint malalignment, it is important for the surgeon to take steps to stabilize the joint during the lengthening process. In this report, a percutaneous method of callus distraction for repair of brachymetatarsia and maintenance of metatarsophalangeal joint alignment is presented.

    Thirty-one carotid artery stenoses were produced in thirty dogs by three different techniques. Twenty-three of these could be cured by transfemoral percutaneous catheter dilatation. High grade tight stenoses may present resistance which cannot be overcome by the catheter. Histological examination of the dilated vessels showed circumscribed changes in the vessel wall, with destruction of elastic membranes. From our experience of catheter dilatation of pelvic and lower limb arteries and of renal arteries, we consider it feasible to use this technique in selected patients with carotid stenosis. (orig.)

    A 70-year-old man with a painful vertebral metastasis was treated with combined percutaneous cryoablation and vertebroplasty therapy (CVT) in one session. The patient was suffering from diffuse visceral metastasized cholangiocarcinoma. After several weeks of back pain, magnetic resonance imaging documented a single L2 bone metastasis. In consultation with the oncologists, palliative combined CVT was administered with the aim of obtaining pain relief and bone stabilization. In our experience this combined treatment is safe and effective for immediate pain relief in painful bone metastases when other standard palliative treatments have failed

    This paper determines whether radiation therapy (RT) is a risk factor for infectious complications (particularly hepatic abscess formation) related to percutaneous biliary drainage (PBD). The authors retrospectively reviewed the charts of 98 consecutive patients who had undergone PBD for obstruction. In 34 patients with benign obstruction, three infectious complications occurred, none of which were hepatic abscess or fatal sepsis. In 39 patients who had malignant obstruction but did not have cholangiocarcinoma, 13 infectious complications occurred, including two hepatic abscesses and three cases of fatal sepsis. Of the 25 patients with cholangiocarcinoma, 15 underwent RT; in these 15 patients, 14 infectious complications occurred, including six hepatic abscesses and two cases of fatal sepsis

    The robustness of immune responses to an antigen could be dictated by the route of vaccine inoculation. Traditional smallpox vaccines, essentially vaccinia virus strains, that were used in the eradication of smallpox were administered by percutaneous inoculation (skin scarification). The modified vaccinia virus Ankara is licensed as a smallpox vaccine in Europe and Canada and currently undergoing clinical development in the United States. MVA is also being investigated as a vector for the delivery of heterologous genes for prophylactic or therapeutic immunization. Since MVA is replication-deficient, MVA and MVA-vectored vaccines are often inoculated through the intramuscular, intradermal or subcutaneous routes. Vaccine inoculation via the intramuscular, intradermal or subcutaneous routes requires the use of injection needles, and an estimated 10 to 20% of the population of the United States has needle phobia. Following an observation in our laboratory that a replication-deficient recombinant vaccinia virus derived from the New York City Board of Health strain elicited protective immune responses in a mouse model upon inoculation by tail scarification, we investigated whether MVA and MVA recombinants can elicit protective responses following percutaneous administration in mouse models. Our data suggest that MVA administered by percutaneous inoculation, elicited vaccinia-specific antibody responses, and protected mice from lethal vaccinia virus challenge, at levels comparable to or better than subcutaneous or intramuscular inoculation. High titers of specific neutralizing antibodies were elicited in mice inoculated with a recombinant MVA expressing the herpes simplex type 2 glycoprotein D after scarification. Similarly, a recombinant MVA expressing the hemagglutinin of attenuated influenza virus rgA/Viet Nam/1203/2004 (H5N1) elicited protective immune responses when administered at low doses by scarification. Taken together, our data suggest that MVA and MVA

    Percutaneous pulmonary valvuloplasty is the preferred interventional procedure for pulmonary valve stenosis. The aim of this study was to evaluate the effectiveness of this technique, assess the factors leading to its success, and determine the long-term results in the pediatric population. The study included 53 patients with pulmonary valve stenosis undergoing percutaneous balloon valvuloplasty between December 1985 and December 2000. Right ventricular size and functional echocardiographic parameters, such as pulmonary regurgitation and residual transvalvular gradient, were assessed during long-term follow-up. Peak-to-peak transvalvular gradient decreased from 74 mmHg [interquartile range, 65-100 mmHg] to 20 mmHg [interquartile range, 14-34 mmHg]. The procedure was unsuccessful in 2 patients (3.77%). The immediate success rate was 73.58%. Follow-up ranged from 10 years to 24 years (median, 15 years). During follow-up, all patients developed late pulmonary regurgitation which was assessed as grade II in 58.4% and grade III in 31.2%. There was only 1 case of long-term restenosis (2.1%). Severe right ventricular dilatation was observed in 27.1% of the patients. None of the patients developed significant right ventricular dysfunction. Pulmonary valve replacement was not required in any of the patients. Percutaneous balloon valvuloplasty is an effective technique in the treatment of pulmonary valve stenosis with good long-term results. Copyright © 2013 Sociedad Española de Cardiología.

    PurposeThe Habib™ VesOpen Catheter is a new endovascular radiofrequency ablation (RFA) device used to treat malignant portal obstruction. The purpose of this study was to evaluate the clinical feasibility and safety of RFA with this device.MethodsWe collected the clinical records and follow-up data of patients with malignant portal obstruction treated with percutaneous endovascular portal RFA using the Habib™ VesOpen Catheter. Procedure-related complications, improvement of symptoms, portal patency, survival, and postoperative biochemical tests were investigated.ResultsThe 31 patients enrolled in the study underwent 41 successful endovascular portal RFA procedures. Patients were divided into a portal-stenting (PS) group (n = 13), which underwent subsequent portal stenting with self-expandable metallic stents, and a non-stenting (NS) group (n = 18), which did not undergo stenting. No procedure-related abdominal hemorrhage or portal rupture occurred. Postablation complications included abdominal pain (n = 26), fever (n = 13), and pleural effusion (n = 15). Improvements in clinical manifestations were observed in 27 of the 31 patients. Of the 17 patients experiencing portal restenosis, 10 underwent successful repeat RFA. The rate of successful repeat RFA was significantly higher in the NS group than in the PS group. Median portal patency was shorter in the PS group than in the NS group. No mortality occurred during the 4 weeks after percutaneous endovascular portal RFA.ConclusionsPercutaneous endovascular portal RFA is a feasible and safe therapeutic option for malignant portal obstruction. Prospective investigations should be performed to evaluate clinical efficacy, in particular, the need to evaluate the necessity for subsequent portal stenting.

    A staged approach of percutaneous coronary intervention (PCI) followed by minimally invasive valve surgery (MIVS) is an alternative to the conventional combined coronary artery bypass and valve surgery for patients with concomitant coronary artery and valve disease. Limited data exist on degree of the completeness of revascularization achieved with this approach and its impact on outcomes. A total of 138 patients, who underwent a staged approach between January 2009 and June 2013, were retrospectively evaluated. Coronary angiograms were reviewed by two cardiologists blinded to outcomes and were then categorized into two groups: complete or incomplete revascularization, which was defined as ≥1 major epicardial coronary arteries of at least 2.0 mm diameter with ≥70% untreated obstruction after the index PCI and before MIVS. Complete and incomplete revascularization was achieved in 105 (76%) and 33 (24%) patients, respectively. The patients with incomplete revascularization had a lower ejection fraction, a higher STS score, and more prior myocardial infarctions and multi-vessel coronary artery disease. There were no differences in the post-operative complications, 30-day mortality, or 3-year survival (84 vs. 83%, P = 0.68). After a median follow-up of 29 months, incompletely revascularized patients had a higher incidence of acute coronary syndrome (2.9 vs. 12.9%, P = 0.05). In patients undergoing a staged approach of PCI followed by MIVS, incomplete revascularization did not significantly impact the short or mid-term survival, but was associated with an increased incidence of acute coronary syndrome at follow-up. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

    more than 6 months. For this systematic review, 45 studies were identified. Of these, for percutaneous adhesiolysis there were 7 randomized controlled trials and 3 observational studies which met the inclusion criteria. For spinal endoscopy, there was one randomized controlled trial and 3 observational studies. Based upon 7 randomized controlled trials showing efficacy, with no negative trials, there is Level I or strong evidence of the efficacy of percutaneous adhesiolysis in the treatment of chronic refractory low back and lower extremity pain. Based upon one high-quality randomized controlled trial, there is Level II to III evidence supporting the use of spinal endoscopy in treating chronic refractory low back and lower extremity pain. The evidence is Level I or strong that percutaneous adhesiolysis is efficacious in the treatment of chronic refractory low back and lower extremity pain. Percutaneous adhesiolysis may be considered as a first-line treatment for chronic refractory low back and lower extremity pain. The evidence is Level II to III that spinal endoscopy is effective in the treatment of chronic refractory low back and lower extremity pain.

    The aim of this study was to determine the risk of scaffold thrombosis (ST) after percutaneous coronary intervention (PCI) with placement of an ABSORB bioresorbable vascular scaffold (BVS) (Abbott Vascular, Santa Clara, California) by conducting a systematic review and meta-analysis. PCI with BVS placement holds great potential, but concern has recently been raised regarding the risk of ST. MEDLINE/PubMed, Cochrane CENTRAL, and meeting abstracts were searched for all studies that included outcomes data for patients after PCI with BVS placement. For studies comparing BVSs with drug-eluting stents (DES), pooled estimates of outcomes, presented as odds ratios (ORs) with 95% confidence intervals (CIs), were generated with random-effects models. Our analysis included 10,510 patients (8,351 with a BVS and 2,159 with DES) with a follow-up of 6.4 ± 5.1 months and 60 ± 11 years of age; 78% were male, 36% had stable angina, and 59% had acute coronary syndrome (ACS). Among patients with a BVS, cardiovascular death occurred in 0.6%, myocardial infarction (MI) in 2.1%, target lesion revascularization in 2.0%, and definite/probable ST in 1.2% of patients. Of BVS patients, 0.27% had acute ST and 0.57% had subacute ST. Meta-analysis demonstrated that patients who received a BVS were at a higher risk of MI (OR: 2.06, 95% CI: 1.31 to 3.22, p = 0.002) and definite/probable ST (OR: 2.06, 95% CI: 1.07 to 3.98, p = 0.03) compared with patients who received DES, whereas there was a trend toward decreased all-cause mortality with a BVS (OR: 0.40, 95% CI: 0.15 to 1.06, p = 0.06). Patients undergoing PCI with a BVS had increased definite/probable ST and MI during follow-up compared with DES. Further studies with long-term follow-up are needed to assess the risk of ST with a BVS. Copyright © 2016 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.

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

    Twenty-one Kimray-Greenfield, 33 bird's nest, and 19 Amplatz vena cava filters were placed percutaneously. The Kimray-Greenfield filter was the most difficult to insert. The major problem was the insertion site, which required venipuncture with a 24-F catheter. Minor hemorrhage was frequent, and femoral vein thrombosis occurred in four patients. No migration, caval thrombosis, or pulmonary emboli were seen after Kimray-Greenfield filter placement. The bird's nest filter was relatively easy to insert, although in two cases the filter prongs could not be adequately seated in the wall of the inferior vena cava. Three patients with bird's nest filters had thrombosis below the filter, and three filters migrated to the heart. One migrated filter could not be removed. One patient had multiple small pulmonary emboli at autopsy. No other pulmonary emboli after filter placement were noted. The Amplatz filter was the easiest of the three filters to insert. Only one patient with an Amplatz filter had thrombosis of the vena cava below the filter. No filter migrations were documented, and no recurrent pulmonary emboli were found on clinical or radiologic follow-up. The Amplatz vena cava filter is easier to place than percutaneous Kimray-Greenfield or bird's nest filters, has a low complication rate, and has proven to be clinically effective in preventing pulmonary emboli

    Full Text Available Introduction: Increasing global prevalence of nephrolithiasis has resulted in the development of new minimally invasive techniques and has also led to the resurgence of established methods such as percutaneous nephrolithotomy (PCNL. This procedure is now recommended as the first option for the treatment of single large or multiple renal stones and those in the inferior calyx. This study was done to assess the complications of PCNL and their management, in our centre. Methods: Medical records of 144 patients who underwent PCNL at Lumbini Medical College Teaching Hospital, during the last one year were reviewed. The demographic data, size, tract number and location of the calculi, and intraoperative and postoperative complications were evaluated. The various parameters of the calculi were evaluated. Descriptive analysis with frequencies was done. Results: Complications occurred in 13 (9.02% patients. Post operative bleeding occurred in seven (4.8% patients, out of which one patient developed pseudoaneurysms and the other developed arteriovenous fistula. One patient developed hypovolemic shock immediately after surgery. Frequent blockage of urine, excessive drainage of urine from the drain site, hemothorax and colonic perforation was seen in one  patient each. One patient had mortality due to post operative bleeding. Complications increased with the number and size of stones and number and site of the tracts. Conclusion: Percutaneous nephrolithotomy has low complication rate in experienced hands and complications depend upon stone size, history of open stone surgery, tract number, and tract location.

    To evaluate the therapeutic efficacy of percutaneous cryotherapy for inoperable patients with malignant pulmonary nodules. We enrolled 14 patients (7 males, 7 females, average age 68.8 years) who had inoperable lung malignancy in this study from August 2006 through July 2009. We evaluated the therapeutic efficacy of cryotherapy for complete or incomplete ablation by follow up chest CT. Using Kaplan Meier statistical methods, we estimated the survival of patients who had undergone cryotherapy and we investigated post cryotherapy complications. Five of the 14 patients underwent complete ablation (35.7%), while 9 of 14 patients underwent incomplete ablation (64.3%). The change in mean size before procedure and at last follow up CT in the complete and incomplete ablation were as follows: 13.2 {+-} 7.6 mm {yields} 3.8 {+-} 2.7 mm, and 18.1 {+-} 6.2 mm {yields} 33.7 {+-} 17.9 mm, respectively. The median survival of patients in the complete and the incomplete groups were 51.5 months and 24 months, respectively. One patient developed a small pneumothorax, which resolved spontaneously. Two patients developed hemoptysis after the procedure, which was controlled within a day. Percutaneous cryotherapy may be an effective and safe therapeutic method for inoperable patients with malignant pulmonary nodules.

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

    To evaluate safe access route and success rate of percutaneous drainage of pelvic fluid collection. The 35 percutaneous drainages of pelvic fluid collection under the CT and fluorosocpic guidance were done in 32 patients. The anterior transabdominal approach was done in 20 patients, while the nine patients used the transgluteal approach through greater sciatic foramen. Three patients, who had septated or noncommunicating abscesses, underwent drainage using both approaches. The catheter was removed when the patient's symptom and laboratory data were improved or the amount of drainage and the size of fluid collection were markedly reduced. Success, partial success and failure were classified. The causes of fluid collection were complication of intraabdominal operation in 27 patient. The diagnosis after drainage included abscess (21), loculated ascites (6), and hematoma (4). The 27 cases (30 procedure) were treated successfully and the mean duration of catheter insertion was 10 days. The partial successes were two cases (2 procedures), which had palliative purpose. Three cases (3 procedures) were failed, which were multiple loculated ascites of pancreatic origin (2) and recurrent abscess (1). The significant complication during the procedure or drainage was not noted

    Thoracolumbar vertebral fracture incidents usually occur secondary to a high velocity trauma in young patients and to minor trauma or spontaneously in older people.Osteoporotic vertebral fractures are the most common osteoporotic fractures and affect one-fifth of the osteoporotic population.Percutaneous fixation by 'vertebroplasty' is a tempting alternative for open surgical management of these fractures.Despite discouraging initial results of early trials for vertebroplasty, cement augmentation proved its superiority for the treatment of symptomatic osteoporotic vertebral fracture when compared with optimal medical treatment.Early intervention is also gaining ground recently.Kyphoplasty has the advantage over vertebroplasty of reducing kyphosis and cement leak.Stentoplasty, a new variant of cement augmentation, is also showing promising outcomes.In this review, we describe the additional techniques of cement augmentation, stressing the important aspects for success, and recommend a thorough evaluation of thoracolumbar fractures in osteoporotic patients to select eligible patients that will benefit the most from percutaneous augmentation. A detailed treatment algorithm is then proposed. Cite this article: EFORT Open Rev 2017;2:293-299. DOI: 10.1302/2058-5241.2.160057.

    Different factors can determine the outcomes of percutaneous nephrolithotomy (PNL). We analyzed the effect of tract length (TL) on outcomes after PNL. We performed a retrospective review of patients undergoing PNL between 2006 and 2011. Patients with preoperative computed tomography (CT), one percutaneous access tract and follow-up imaging within 3 months were included. TL was defined as distance between the skin to the calyx of puncture as measured on preoperative CT. Measurements were independently performed by two urologists and the average was used for analysis. Stone-free rate (SFR) was defined as zero fragments on follow-up imaging. Factors independently associated with the likelihood of being stone-free after PNL were determined using multivariable analysis adjusted for TL, location of access, the presence of incomplete or complete staghorn calculi and type of follow-up imaging. Complications (Clavien score) were independently assessed. A total of 222 patients were included. Median stone burden and body mass index (BMI) was 239.4 mm(2) and 30.5 [interquartile range (IQR): 25.7-36.2]. The median TL was 85.0 mm (IQR: 70.3-100.0) and highly correlated with BMI (ρ = 0.66, p PNL. PNL is a safe and effective treatment for stones in patients with differing body habitus.

    Thirty patients with obstructive jaundice with plasma bilirubin values greater than 200 mumol/L were randomized at the time of percutaneous transhepatic Cholangiography to undergo immediate or delayed surgery. The patients who had preoperative percutaneous transhepatic biliary drainage (PTBD) for 13.8 +/- 5.8 days had fewer surgical complications than did patients who underwent immediate surgery (p less than 0.02), although when the complications of PTBD were included this advantage was diminished. Immediate surgery caused greater deterioration of renal function as measured by plasma urea, plasma B 2-microglobulin, phosphate clearance, uric acid clearance, and maximal concentrating ability than occurred after PTBD or delayed surgery. The improvement in phosphate clearance that followed PTBD was sustained through delayed surgical treatment, indicating better tubular function in these patients. This article supports the concept that preoperative PTBD will reduce surgical morbidity and will result in less renal impairment than will immediate surgery. However, the morbidity rates of the PTBD procedure will preclude its wide use.

    To describe outcomes of patients with malignant biliary obstruction who undergo salvage percutaneous biliary drainage after occlusion of endoscopic biliary stents. A single-center retrospective review was performed of 47 patients (25 men, 22 women) who underwent percutaneous biliary drainage for recurrent obstruction after endoscopic stent placement between 2005 and 2015. Primary malignancies were bile duct (n = 13), colorectal (n = 11), gallbladder (n = 7), pancreas (n = 5), hepatocellular (n = 4), and other (n = 7). Indication for salvage drain placement was infection (n = 19) and jaundice or need to decrease bilirubin (n = 28). Kaplan-Meier and Cox regression methods were used for survival analysis. Logistic and multivariate regressions were employed to identify factors associated with survival. Median survival after salvage biliary drain placement was 1.8 months (95% confidence interval [CI], 1.3-2.7). Elevated international normalized ratio (INR) ≥ 1.5 before drainage was associated with poorer survival after drainage (median survival 0.7 months vs 2.4 months, P drainage (1.2 months vs 5.4 months, P drainage. Elevated bilirubin and INR before drainage portend a poor prognosis. Copyright © 2016 SIR. Published by Elsevier Inc. All rights reserved.

    To examine the value of magnetic resonance (MR) imaging for predicting the occurrence of skin burns in patients with venous malformations who undergo percutaneous alcohol embolization was the objective of the study. Pre-procedural MR imaging at 1.5 T from 40 patients with venous malformations who had undergone percutaneous alcohol embolization was retrospectively reviewed by two observers for these features: anatomic location, definition (well-defined or ill-defined), and the presence of skin, subcutaneous tissue, muscle, tendon, bone, joint, and deep venous system involvement. One observer recorded the length of skin involvement and volume of the malformation. Univariate and multivariate analysis tests were used to determine whether an association between the occurrence of skin burns and MR imaging features existed. The anatomic locations of the venous malformations were the lower extremity (20 out of 40), upper extremity (11 out of 40), trunk (four out of 40), head/neck (three out of 40) and pelvis (two out of 40). Of the 40 subjects, 15% (six out of 40) experienced skin burns. There was a significant association between the absence of muscle involvement (p=0.0198) as well as the length of skin involvement (p=0.027), with the occurrence of skin burns. Malformation size and all other features were not significantly associated with skin burns. Skin burns in patients with venous malformations treated with alcohol embolization are associated with the length of skin involvement and with the absence of deeper tissue involvement, as depicted on MR imaging.

    A novel 1-step percutaneous access sheath NS has been developed that allows the insertion of a dilating balloon and renal access sheath in a single step. We present the initial human experience with this sheath. We performed a retrospective chart and database review of the initial 30 consecutive patients undergoing percutaneous nephrostolithotomy using the NS. Data collected included patient demographics, operative and recovery parameters, and complications. Mean patient age was 50.4 years (range 11 to 81), mean body mass index was 31.63 kg/m(2) (range 17.1 to 65) and mean preoperative stone area was 6.23 cm(2) (range 1 to 14.6). Six and 3 patients had full and partial staghorn calculi, respectively. Access was achieved via the upper pole in 16 patients, middle pole in 7 and lower pole in 7. Mean operative time was 114.8 minutes (range 61 to 237). Mean estimated blood loss was 145.5 cc (range 10 to 500) and mean postoperative hospital stay was 4.89 days (range 2 to 14). A total of 23 patients (76.7%) had no residual calculi on postoperative computerized tomography, 5 (16.7%) had residual fragments 4 mm or less and 2 (6.7%) had residual stone fragments greater than 4 mm. There were no complications related to the NS. The NS is safe, easy to use and has potential advantages compared to currently available renal access sheaths.

    The aim of this study was to describe our initial experience with a gold flexible linear fiducial marker and to evaluate the safety and technical and clinical efficacy of stereotactic body radiotherapy using this marker for malignant liver tumors. Between July 2012 and February 2015, 18 patients underwent percutaneous fiducial marker placement before stereotactic body radiotherapy for malignant liver tumors. We evaluated the technical and clinical success rates of the procedure and the associated complications. Technical success was defined as successful placement of the fiducial marker at the target site, and clinical success was defined as the completion of stereotactic body radiotherapy without the marker dropping out of position. All 18 fiducial markers were placed successfully, so the technical success rate was 100% (18/18). All 18 patients were able to undergo stereotactic body radiotherapy without marker migration. Thus, the clinical success rate was 100% (18/18). Slight pneumothorax occurred as a minor complication in one case. No major complications such as coil migration or bleeding were observed. The examined percutaneous fiducial marker was safely placed in the liver and appeared to be useful for stereotactic body radiotherapy for malignant liver tumors

    Adjacent segment disease (ASD) requiring treatment or re-operation is a common problem after surgery on the lumbar spine. The hypothesis of this retrospective study was that ASD occurs less often following lumbar spine fusion in patients who undergo percutaneous minimally invasive (MIS) instrumentation than in those in whom open instrumentation is used. A case-control study was performed on consecutive patients who had undergone staged single or two level anterior lumbar interbody fusion for degenerative conditions followed by open or MIS instrumentation from 2002 to 2005 in our institution. ASD was defined as that necessitating additional procedures for new symptoms related to an adjacent lumbar dermatome. One hundred and seventeen patients met the inclusion criteria. Of these, 53 had been followed up by chart or medical record review for longer than one year. There were 23 patients in the MIS group and 30 in the open group. Of the 30 patients in the open group, 9 had developed ASD (30%). Of the 23 patients in the MIS group, 7 had developed ASD (30%). This difference is not statistically significant (P = 1.00). Contrary to our hypothesis, there was no significant difference in incidence of ASD in patients who had underwent open versus percutaneous instrumentation following anterior lumbar interbody fusion. © 2014 Chinese Orthopaedic Association and Wiley Publishing Asia Pty Ltd.

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

    Objective: To present a preliminary latest procedure for portal hypertension and evaluate the technical feasibility and efficacy of portacaval shunt creation through the percutaneous transhepatic approach in order to make a hemodynamic comparison with that of the classic TIPS. Methods: Thirty-eight patients with portal hypertension (36 men; mean age 57 years, range 32-73) were referred for PTPS procedure because of bleeding varices (n=36), intractable ascites (n=1), and hepatopulmonary syndrome (n=1). The severity of liver disease was classified as Child-Pugh B in 27 and C in 11. The PTPS was created by a percutaneous transhepatic puncture into right portal vein and then through left portal vein to the hepatic segment of IVC followed by a prefabrication stress stent-graft placement at the very site. Results: Technical and functional success of 100% was achieved in all patients, without related complications. The postprocedural portal vein-IVC gradients mean 13 cmH 2 O was achieved with the follow-up period mean 493 days. No recurrence of variceal bleeding and controlled refractory ascites were achieved, and still more with primary patency rate of the involved vascular structure up to 94.8% at 365 days, much better than classic TIPS. Conclusions: Portacaval shunt creation using the prefabrication stress stent via percutaneous transhepatic technique is safe and feasible. the compact coincidence was obtained between the stent and the involved vessel with restoration of intrahepatic portal venous hemodynamics together with partial lowering of portal venous pressure and guaranteeing intrahepatic perfusion through right portal vein. It is also obviously to have postoperative prevention of shunt restenoses and lowering postoperative incidence of hepato-encephalopathy. (authors)

    Celiac trunk (CT) compression syndrome caused by the median arcuate ligament (MAL) is a rarely diagnosed disease because of its nonspecific symptoms, which cause a delay in the correct diagnosis. Intestinal ischemia occurs, which causes symptoms of abdominal angina. One method of treatment for this disease is surgical release of the CT - the intersection of the MAL. Laparoscopy is the first step of the hybrid technique combined with percutaneous angioplasty and stenting of the CT. To demonstrate the usefulness and advantages of the laparoscopic approach in the treatment of Dunbar syndrome. Between 2013 and 2016 in the General and Minimally Invasive Surgery Department of the Medical Sciences Faculty of the University of Warmia and Mazury in Olsztyn, 6 laparoscopic procedures were performed because of median arcuate ligament syndrome. During the laparoscopy the MAL was cut with a harmonic scalpel. One month after laparoscopy 5 patients had Doppler percutaneous angioplasty of the CT with stent implantation in the Vascular Surgery Department in Pomeranian Medical University in Szczecin. In one case, there was a conversion of laparoscopic surgery to open due to unmanageable intraoperative bleeding. In one case, postoperative ultrasound examination of the abdominal cavity demonstrated the presence of a large hematoma in the retroperitoneal space. All patients reported relief of symptoms in the first days after the operation. The hybrid method, combining laparoscopy and angioplasty, seems to be a long-term solution, which increases the comfort of the patient, brings the opportunity for normal functioning and minimizes the risk of restenosis.

    Although patients may experience a quick recovery followed by rapid discharge after percutaneous coronary interventions (PCIs), continuity of care from hospital to home can be particularly challenging. Despite this fact, little is known about the experiences of care across the interface between secondary and primary healthcare systems in patients undergoing PCI. To explore how patients undergoing PCI experience continuity of care between secondary and primary care settings after early discharge. The study used an inductive exploratory design by performing in-depth interviews of 22 patients at 6-8 weeks after PCI. Nine were women and 13 were men; 13 were older than 67 years of age. Eight lived remotely from the PCI centre. Patients were purposively recruited from the Norwegian Registry for Invasive Cardiology. Interviews were analysed by qualitative content analysis. Patients undergoing PCI were satisfied with the technical treatment. However, patients experienced an unplanned patient journey across care boundaries. They were not receiving adequate instruction and information on how to integrate health information. Patients also needed help to facilitate connections to community-based resources and to schedule clear follow-up appointments. As high-technology treatment dramatically expands, healthcare organisations need to be concerned about all dimensions of continuity. Patients are witnessing their own processes of healthcare delivery and therefore their voices should be taken into greater account when discussing continuity of care. Nurse-led initiatives to improve continuity of care involve a range of interventions at different levels of the healthcare system.
