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

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

    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.

    Patients undergoing acute left main (LM) coronary artery revascularization have a high mortality and natriuretic peptides such as N-terminal pro-B-type (NT-proBNP) have been shown to have prognostic value in patients with acute coronary syndromes. The present study looked at the prognostic value of NT-proBNP in these patients. We studied all consecutive patients undergoing acute LM coronary artery percutaneous coronary intervention between January 2005 and December 2008 in whom NT-proBNP was measured (n=71). We analyzed the clinical characteristics and the short- and long-term outcomes in relation to NT-proBNP level at admission. Median NT-proBNP was 1,364 ng/L, ranging from 46 to 70,000 ng/L. NT-proBNP was elevated in 63 (89%) patients and was ≥1,000ng/L in 42 (59%). Log NT-proBNP (hazard ratio [HR] 3.51, 95% confidence interval [CI] 1.55-7.97, P=0.003) and left ventricular ejection fraction (HR 0.95, 95%CI 0.91-0.99, P=0.007) were predictors for all-cause mortality. Log NT-proBNP was the only independent significant predictor of cardiovascular mortality. In-hospital mortality was 0% for patients with NT-proBNP value for NT-proBNP in patients undergoing acute LM coronary artery intervention.

    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.

    Peri-procedural myocardial infarction (PMI) occurs in a small but significant portion of patients undergoing percutaneous intervention (PCI). The underlying mechanisms are complex and may include neurohormonal activation and release of vasoactive substances resulting in disruption of the coronary microcirculation. Endothelin in particular has been found in abundance in atherosclerotic plaques and in systemic circulation following PCI, and may be a potential culprit for PMI through its action on microvascular vasoconstriction, and platelet and neutrophil activation. In this study we aim to characterize the behavior of the coronary microcirculation during a PCI with the index of microvascular resistance (IMR) and the effect of peri-procedural endothelin antagonism. The ENDORA-PCI trial is a randomized, double-blind, placebo-controlled, single-center clinical trial designed to evaluate the efficacy of endothelin antagonism in attenuating the peri-procedural rise in IMR as a surrogate marker for PMI. The patients of interest are those with non-ST elevation acute coronary syndrome (NSTEACS) undergoing PCI, and we aim to recruit 52 patients overall to give the study a power of 80 % at an α level of 5 %. Patients will be randomized in a 1:1 fashion to either Ambrisentan, an endothelin antagonist, or placebo, prior to their PCI. IMR will be measured before and after PCI. The primary endpoint is the difference in peri-procedural changes in patients' IMR between the two groups. The ENDORA-PCI study will investigate whether endothelin antagonism with Ambrisentan attenuates the peri-procedural rise in IMR in patients with NSTEACS undergoing PCI, and thus potentially the risk of PMI.

    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.

    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).

    Abstract Aims The aim of this study was to investigate the association between hypothyroidism and major adverse cardiovascular and cerebral events (MACCE) in patients undergoing percutaneous coronary intervention (PCI). Methods and results Two thousand four hundred and thirty patients who underwent PCI were included. Subjects were divided into two groups: hypothyroidism ( n = 686) defined either as a history of hypothyroidism or thyroid-stimulating hormone (TSH) ≥5.0 mU/mL, and euthyroidism ( n = 1744) defined as no history of hypothyroidism and/or 0.3 mU/mL ≤ TSH hypothyroidism were further categorized as untreated ( n = 193), or those taking thyroid replacement therapy (TRT) with adequate replacement (0.3 mU/mL ≤ TSH hypothyroidism compared with those with euthyroidism (MACCE: HR: 1.28, P = 0.0001; myocardial infarction (MI): HR: 1.25, P = 0.037; heart failure: HR: 1.46, P = 0.004; revascularization: HR: 1.26, P = 0.0008; stroke: HR: 1.62, P = 0.04). Compared with untreated patients or those with inadequate replacement, adequately treated hypothyroid patients had a lower risk of MACCE (HR: 0.69, P = 0.005; HR: 0.78, P = 0.045), cardiac death (HR: 0.43, P = 0.008), MI (HR: 0.50, P = 0.0004; HR: 0.60, P = 0.02), and heart failure (HR: 0.50, P = 0.02; HR: 0.52, P = 0.017). Conclusion Hypothyroidism is associated with a higher incidence of MACCE compared with euthyroidism in patients undergoing PCI. Maintaining adequate control on TRT is beneficial in preventing MACCE.

    2010-01-01

    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.

    Background and aims: Cardiovascular disease (CVD) is the leading cause of death in the Middle East. We sought to study the prevalence and coexistence of 6 cardiovascular risk factors (RFs) among patients who underwent percutaneous coronary intervention (PCI), and to evaluate the impact of age and gender on the presence of multiple RFs. In this prospective, multicenter study, 2426 consecutive patients were enrolled. Mean age was 59.0 ± 10.1 years and 500 (20.6%) were women. Acute coronary syndrome and stable coronary disease were the indications for PCI in 77.1% and 22.9%, respectively. Hypertension was present in 62.3%, diabetes in 53.8%, hypercholesterolemia in 48.8%, smoking in 43.5%, family history of premature CVD 39.4% and obesity in 28.8%. Only 3.8% did not have any of these RFs. Presence of ⩾3 and ⩾4 RFS was observed in 57.4% and 29.5% of patients, respectively. Presence of ⩾3 RFs was more common in women than men (69.0% vs. 54.5%, p  Eastern population undergoing PCI. More than half and more than one-fourth of the patients had at least 3 or 4 RFs; respectively. More women than men and more middle aged patients than older or younger patients had significantly higher rates of presence of multiple RFs.

    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. (author). 9 refs., 3 figs

    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.

    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

    This is a prospective multicenter registry designed to evaluate the incidence of adverse cardiovascular events in Middle Eastern patients undergoing percutaneous coronary interventions (PCI). The registry was also designed to determine the predictors of poor outcomes in such patients. We enrolled 2426 consecutive patients who underwent PCI at 12 tertiary care centers in Jordan between January 2013 and February 2014. A case report form was used to record data prospectively at hospital admission, discharge, and 12 months of follow-up. Mean age was 56 ± 11 years, females comprised 21% of the study patients, 62% had hypertension, 53% were diabetics, and 57% were cigarette smokers. Most patients (77%) underwent PCI for acute coronary syndrome. In-hospital and 1-year mortality rates were 0.78% and 1.94%, respectively. Definite or probable stent thrombosis occurred in 9 patients (0.37%) during hospitalization and in 47 (1.94%) at 1 year. Rates of target vessel repeat PCI and coronary artery bypass graft surgery at 1 year were 3.4% and 0.6%, respectively. The multivariate analysis revealed that cardiogenic shock, congestive heart failure, ST-segment deviation, diabetes, and major bleeding were significantly associated with higher risk of 1-year mortality. In this first large Jordanian registry of Middle Eastern patients undergoing PCI, patients treated were relatively young age population with low in-hospital and 1-year adverse cardiovascular events. Certain clinical features were associated with worse outcomes and may warrant aggressive therapeutic strategies.

    Full Text Available Gastrointestinal obstruction is a common preterminal event in patients with gastric and pancreatic cancer who often undergo palliative bypass surgery. Although endoscopic palliation with self-expandable metallic stents has emerged as a safe and effective alternative to surgery, experience with this technique remains limited. In particular, a proximal jejunal obstruction requires more technical expertise than a duodenal obstruction. Palliative treatment modalities include both surgical and nonsurgical approaches. In this report, we describe the successful placement of self-expandable metallic stents at the proximal jejunum using a combination of percutaneous endoscopic, intraoperative, and transstomal stenting. Usually endoscopy is not indicated in cases of proximal jejunal obstruction, but some cases may require palliative endoscopy instead of bypass operation.

    Full Text Available Selecting an ideal antithrombotic therapy for elderly patients with atrial fibrillation (AF undergoing percutaneous coronary intervention (PCI can be challenging since they have a higher thromboembolic and bleeding risk than younger patients. The current study aimed to assess the efficacy and safety of triple therapy (TT: oral anticoagulation plus dual antiplatelet therapy: aspirin plus clopidogrel in patients ≥75 years of age with atrial fibrillation (AF undergoing percutaneous coronary intervention (PCI.A prospective multicenter study was conducted from 2003 to 2012 at 6 Spanish teaching hospitals. A cohort study of consecutive patients with AF undergoing PCI and treated with TT or dual antiplatelet therapy (DAPT was analyzed. All outcomes were evaluated at 1-year of follow-up.Five hundred and eighty-five patients, 289 (49% of whom were ≥75 years of age (79.6±3.4 years; 33% women were identified. TT was prescribed in 55.9% of patients at discharge who had a higher thromboembolic risk (CHA2DS2VASc score: 4.23±1.51 vs 3.76±1.40, p = 0.007 and a higher bleeding risk (HAS-BLED ≥3: 88.6% vs 79.2%, p = 0.02 than those on DAPT. Therefore, patients on TT had a lower rate of thromboembolism than those on DAPT (0.6% vs 6.9%, p = 0.004; HR 0.08, 95% CI: 0.01-0.70, p = 0.004. Major bleeding events occurred more frequently in patients on TT than in those on DAPT (11.7% vs 2.4%, p = 0.002; HR 5.2, 95% CI: 1.53-17.57, p = 0.008. The overall mortality rate was similar in both treatment groups (11.9% vs 13.9%, p = 0.38; however, after adjustment for confounding variables, TT was associated with a reduced mortality rate (HR 0.33, 95% CI: 0.12-0.86, p = 0.02.In elderly patients with AF undergoing PCI, the use of TT compared to DAPT was associated with reduced thromboembolism and mortality rates, although a higher rate of major bleeding.

    Loin pain haematuria syndrome (LPHS) is a severe renal pain condition of uncertain origin and often resistant to treatment. Nephrectomy and renal autotrasplantation have occasionally been performed in very severe cases. Its pathogenesis is controversial. A 40-year-old hypertensive lady was diagnosed with LPHS after repeated diagnostic imaging procedures had ruled out any renal, abdominal or spinal conditions to justify pain. Notwithstanding treatment with three drugs, she had frequent hypertensive crises during which the loin pain was dramatically exacerbated. Vascular causes of the pain and hypertension were investigated and excluded. Her renal function was normal. The patient was referred to a multidisciplinary pain clinic, but had no significant improvement in her pain symptoms despite the use of non-steroidal anti-inflammatory drugs, adjuvant antidepressants and opioid-like agents. The pain and the discomfort were so severe that her quality of life was very poor, and her social and professional activities were compromised. Nephrectomy and renal autotransplantation have occasionally been performed in these cases. Since visceral pain signals flow through afferent sympathetic fibres, we felt that percutaneous catheter-based radiofrequency ablation of the renal sympathetic nerve fibres (recently introduced for the treatment of drug-resistant hypertension) could be valuable for pain relief. We treated the patient with radiofrequency ablation (Medtronic Symplicity Catheter) applied only to the right renal artery. After a 6-month follow-up, the patient is pain free and normotensive with all drugs withdrawn. She has experienced no hypertensive crises in the meantime. This observation suggests that percutaneous sympathetic denervation could prove to be an effective mini-invasive strategy for the treatment of chronic renal pain, and LPHS in particular.

    To determine the gender differences in cardiovascular risk profile and outcomes among patients undergoing percutaneous coronary intervention (PCI). Methods: In a prospective multicenter study of consecutive Middle Eastern patients managed with PCI from January 2013 to February 2014 in 12 tertiary care centers in Amman and Irbid, Jordan. Clinical and coronary angiographic features, and major cardiovascular events were assessed for both genders from hospital stay to 1 year. Results: Women comprised 20.6% of 2426 enrolled patients, were older (mean age 62.9 years versus 57.2 years), had higher prevalence of hypertension (81% versus 57%), diabetes (66% versus 44%), dyslipidemia (58% versus 46%), and obesity (44% versus 25%) compared with men, p less than 0.001. The PCI for ST-segment elevation myocardial infarction was indicated for fewer women than men (23% versus 33%; p=0.001). Prevalence of single or multi-vessel coronary artery disease was similar in women and men. More women than men had major bleeding during hospitalization (2.2% versus 0.6%; p=0.003) and at one year (2.5% versus 0.9%; p=0.007). There were no significant differences between women and men in mortality (3.1% versus 1.7%) or stent thrombosis (2.1% versus 1.8%) at 1 year. Conclusion: Middle Eastern women undergoing PCI had worse baseline risk profile compared with men.Except for major bleeding, no gender differences in the incidence of major adverse cardiovascular events were demonstrated.

    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.

    The advent of potent antiplatelet and antithrombotic agents over the past decade has resulted in significant improvement in reducing ischemic events in acute coronary syndrome (ACS). However, the use of antiplatelet and antithrombotic combination therapy, often in the settings of percutaneous coronary intervention (PCI), has led to an increase in the risk of bleeding. In patients with non-ST elevation myocardial infarction treated with antithrombotic agents, bleeding has been reported to occur in 0.4%–10% of patients, whereas in patients undergoing PCI, periprocedural bleeding occurs in 2.2%–14% of cases. Until recently, bleeding was considered an intrinsic risk of antithrombotic therapy, and efforts to reduce bleeding have received little attention. There have been increasing data demonstrating that bleeding is associated with adverse outcomes, including myocardial infarction, stroke, and death. Therefore, it is imperative to optimize patient outcomes by adopting pharmacological and nonpharmacological strategies to minimize bleeding while maximizing treatment efficacy. In this paper, we present a review of the bleeding classifications used in large-scale clinical trials in patients with ACS and those undergoing PCI treated with antiplatelets and antithrombotic agents, adverse outcomes, particularly mortality associated with bleeding complications, and suggested predictive risk factors. Potential mechanisms of the association between bleeding and mortality and strategies to reduce bleeding complications are also discussed. PMID:21915172

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

    Full Text Available Background and Aims: Neuraxial anaesthesia has recently become popular for percutaneous nephrolithotomy (PCNL. We conducted a study comparing general anaesthesia (GA with segmental (T6–T12 epidural anaesthesia (SEA for PCNL with respect to anaesthesia and surgical characteristics. Methods: Ninety American Society of Anesthesiologists Physical Status-I and II patients undergoing PCNL randomly received either GA or SEA. Overall patient satisfaction was the primary end point. Intraoperative haemodynamics, epidural block characteristics, post-operative pain, time to rescue analgesic, total analgesic consumption, discharge times from post-anaesthesia care unit, surgeon satisfaction scores and stone clearance were secondary end points. Parametric data were analysed by Student's t-test while non-parametric data were compared with Mann–Whitney U-test. Results: Group SEA reported better patient satisfaction (P = 0.005. Patients in group GA had significantly higher heart rates (P = 0.0001 and comparable mean arterial pressures (P = 0.24. Postoperatively, time to first rescue analgesic and total tramadol consumption was higher in Group GA (P = 0.001. Group SEA had lower pain scores (P = 0.001. Time to reach Aldrete's score of 9 was shorter in group SEA (P = 0.0001. The incidence of nausea was higher in group GA (P = 0.001; vomiting rates were comparable (P = 0.15. One patient in group SEA developed bradycardia which was successfully treated. Eight patients (18% had hypertensive episodes in group GA versus none in group SEA (P = 0.0001. One patient in GA group had pleural injury and was managed with intercostal drain. Stone clearance and post-operative haemoglobin levels were comparable in both groups. Conclusion: PCNL under SEA has a role in selected patients, for short duration surgery and in expert hands.

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

    Bivalirudin use as a procedural anticoagulant in patients undergoing percutaneous coronary intervention (PCI) is associated with a lower incidence of thrombocytopaenia compared to other antithrombotic agents. We aimed to evaluate the prognostic impact of baseline thrombocytopaenia and early changes in platelet counts among patients undergoing PCI with exclusive use of bivalirudin. We evaluated 7,505 patients who underwent PCI over a period of eight years. Patients who received unfractionated heparin and glycoprotein IIb/IIIa receptor inhibitors were specifically excluded. Eight hundred and fifty-eight (11.4%) patients had baseline thrombocytopaenia and 451 (6.0%) developed acquired thrombocytopaenia. After adjustment for potential covariates, moderate to severe acquired thrombocytopaenia was the strongest independent predictor (HR 4.34, 95% CI: 2.13-8.84; pevents, which included major adverse cardiac events and major bleeding complications. Age, male gender, baseline platelet count and intra-aortic balloon pump (IABP) insertion were independent predictors of in-hospital acquired thrombocytopaenia. After a mean follow-up of 2.6±1.7 years, moderate to severe baseline thrombocytopaenia (HR 2.42, 95% CI: 1.79-3.29; p67 k) were significant predictors of mortality. In patients undergoing PCI with bivalirudin, moderate to severe baseline and acquired thrombocytopaenia along with severe changes in platelet count are associated with higher long-term mortality.

    Periprocedural myocardial injury (PMI) following percutaneous coronary intervention (PCI) has received great attention due to its significant association with mortality and morbidity. Accordingly, cardioprotection during PCI is one of the important therapeutic concerns. Regarding the potential cardiovascular benefits of pentoxifylline this study was performed to evaluate whether the pretreatment pentoxifylline could reduce PMI in patients who are undergoing elective PCI. A randomized clinical trial on 85 patients undergoing elective PCI was performed. The intervention group (n = 41) received 1200 mg pentoxifylline in divided doses plus the standard treatment before PCI, while the control group (n = 44) received the standard treatment. For assessing myocardial damage during PCI, the levels of CK-MB and troponin-I were measured at baseline, 8, and 24 h after the procedure. Then, patients were followed up for a 1-month period regarding the major adverse cardiac effect. Comparing with the control group, no significant change of CK-MB at 8 (p = 0.315) and 24 h (p = 0.896) after PCI was documented in pentoxifylline group. Similarly, no significant change was found in troponin-I at 8 (p = 0.141) and 24 h (p = 0.256) after PCI. This study could not support the pretreatment with pentoxifylline in the prevention of PMI in patients undergoing elective PCI. However, the trend was toward the potential benefit of pentoxifylline.

    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.

    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.

    Percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) has undergone impressive progress during the last decade, both in strategies and equipment. It is unknown whether technical refinement has translated into improved outcomes in women undergoing CTO-PCI. A total of 2002 consecutive patients (17% females, mean age 65.2 ± 10.7 years) undergoing PCI of at least one CTO lesion at our center between 01/2005 and 12/2013 were evaluated. The incidence of adverse events was compared between two time series (2005-2009 and 2010-2013). A significant increase in adverse lesion characteristics over time was noted in both, women and men (p men but not in women (p trend  men and p trend =0.9 in women). The incidence of procedural complications was significantly higher in women as compared to men and increased over the study period in women (p men. Accordingly, multivariate logistic regression analysis identified female sex as a strong predictor of PCI-related complications in recent years, while this was not the case in earlier years (adjusted HR 2.03, 95% CI 0.62-6.6, p = 0.2 and adjusted HR 4.7, 95% CI 1.8-12.3, p = 0.002, respectively, p men (log rank = 0.046), while no changes were observed in women. While higher success rates and a reduced rate of MACE have been achieved in men, the incidence of procedural complications in women undergoing CTO-PCI has increased over time.

    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)

    Rates of referral to cardiac rehabilitation after percutaneous coronary intervention (PCI) have been historically low despite the evidence that rehabilitation is associated with lower mortality in PCI patients. This study sought to determine the prevalence of and factors associated with referral to cardiac rehabilitation in a national PCI cohort, and to assess the association between insurance status and referral patterns. Consecutive patients who underwent PCI and survived to hospital discharge in the National Cardiovascular Data Registry between July 1, 2009 and March 31, 2012 were analyzed. Cardiac rehabilitation referral rates, and patient and institutional factors associated with referral were evaluated for the total study population and for a subset of Medicare patients presenting with acute myocardial infarction. Patients who underwent PCI (n = 1,432,399) at 1,310 participating hospitals were assessed. Cardiac rehabilitation referral rates were 59.2% and 66.0% for the overall population and the AMI/Medicare subgroup, respectively. In multivariable analyses, presentation with ST-segment elevation myocardial infarction (odds ratio 2.99; 95% confidence interval: 2.92 to 3.06) and non-ST-segment elevation myocardial infarction (odds ratio: 1.99; 95% confidence interval: 1.94 to 2.03) were associated with increased odds of referral to cardiac rehabilitation. Models adjusted for insurance status showed significant site-specific variability in referral rates, with more than one-quarter of all hospitals referring rehabilitation. Site-specific variation in referral rates is significant and is unexplained by insurance coverage. These findings highlight the potential need for hospital-level interventions to improve cardiac rehabilitation referral rates after PCI. Copyright © 2015 American College of Cardiology Foundation.

    Postconditioning can affect the infarct size in acute myocardial infarction (AMI). However, few studies show an effect of different postconditioning cycles on AMI aged patients. This study sought to assess the effect of different postconditioning cycles on prognosis in aged patients with AMI who underwent primary percutaneous coronary intervention (PCI). 74 aged patients were randomly assigned to three groups. Control group; PC-1 group accepted postconditioning 4 cycles of 30 s inflation and 30 s deflation; PC-2 group accepted postconditioning 4 cycles of 60 s. Creatine kinase MB (CK-MB), troponin I (cTnI), high-sensitive C-reactive protein (hs-CRP) and corrected Thrombolysis in Myocardial Infarction (TIMI) frame counts (CTFC) were analyzed before andafter treatment. All patients received an echocardiographic examination for whole heart function, wall motion score index (WMSI) and single-photon emission computed tomography (SPECT) examination at 7 days and 6 months after treatment. S: The peak of CK-MB, postoperative 72 h cTnI and CTFC were significantly attenuated by postconditioning when compared with the control group. The hs-CRP of the postconditioning group was lower than the control group 24 h postoperative. No difference was observed between PC-1 and PC-2 group about the effect described above. At 7 days, heart function in the postconditioning group was improved when compared with the control group. At 6 months, the WMSI and SPECT score significantly reduced in the PC-2 group compared with the control and PC-1 groups, but there was no difference among the three groups about echo data except the left ventricular end-systolic diameter. Postconditioning is significantly beneficial to prognosis in aged patients with AMI. The cardiac protective effect of 4 cycles of 60 s procedure was observed in WMSI and SPECT. It is favorable to implement this procedure in aged patients with AMI in clinic.

    To investigate initial pain relief and subsequent recurrence after percutaneous balloon compression (PBC) and describe its association with the nature of trigeminal pain, previous procedures, or other clinical factors. A total of 222 patients with medically refractory trigeminal pain treated with PBC at Mayo Clinic Florida between 1998 and 2017 were enrolled into this study. Patients were divided into those with typical trigeminal neuralgia (TN) and those with atypical trigeminal pain. The postprocedural rate of pain recurrence and associations between patient characteristics and recurrence were studied. One hundred fifty-two patients had TN and 70 patients had atypical pain. At the last follow-up, 158 patients had excellent pain relief, 37 had good pain relief, 11 had fair pain relief, and 16 had poor pain relief. The median duration of follow-up was 31.1 months. Patients with atypical pain were less likely to have an excellent result compared with patients with typical pain (61.4% vs. 82.9%; P < 0.001). Recurrence was observed in 103 patients (46.4%) and was associated with previous procedures (hazard ratio, 1.658; 95% confidence interval, 1.09-2.49; P = 0.017). Other clinical factors were not significant. Our study demonstrates the safety and efficacy of PBC, with 88% of patients pain-free at last follow-up. Patients with atypical pain have worse outcomes, and patients with previous procedures have a higher risk of recurrence. Repeat surgery does not decrease efficacy. We recommend conservative parameter selection at the initial procedure. Copyright © 2018 Elsevier Inc. All rights reserved.

    Prediabetes is an independent risk factor for cardiovascular disease. However, data on the long term adverse clinical outcomes of prediabetic patients undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) are scarce. The study population comprised 674 consecutive non-diabetic patients who underwent elective PCI between April 2007 and November 2010. Prediabetes was defined as hemoglobin A1c (HbA1c) of 5.7% to 6.4%. Two-year cumulative clinical outcomes of prediabetic patients (HbA1c of 5.7% to 6.4%, n=242) were compared with those of a normoglycemic group (prediabetes group. There was no significant difference between the two groups in coronary angiographic parameters, except for a higher incidence of diffuse long lesion in the prediabetes group. For prediabetic patients, trends toward higher incidences of binary restenosis (15.6% vs. 9.8 %, p=0.066) and late loss (0.71±0.70 mm vs. 0.59±0.62 mm, p=0.076) were noted. During the 24 months of follow up, the incidence of mortality in prediabetic patients was higher than that in normoglycemic patients (5.5% vs. 1.5%, p=0.007). In our study, a higher death rate and a trend toward a higher incidence of restenosis in patients with prediabetes up to 2 years, compared to those in normoglycemic patients, undergoing elective PCI with contemporary DESs. © Copyright: Yonsei University College of Medicine 2018.

    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.

    Membranous obstruction is the most common cause of Budd-Chiari syndrome in Orientals. Recently, percutaneous transluminal balloon angioplasty (PTBA) has been successfully applied as a treatment of membranous obstruction. We evaluated etiologies and clinical manifestations in our cases and the usefulness of PTBA. Twelve cases of Budd-Chiari syndrome were analyzed. 50.3 years was the average age of the cases (ranging from 37 to 67 years). Major symptoms or signs were superficial collateral vessels on the chest or the abdomen in 6 cases, ascites in 3, abdominal pain in 4, hepatomegaly in 4, splenomegaly in 3, melena or hematemesis in 2, and leg edema in 2. Upper gastrointestinal endoscopy showed esophageal varices in 6 cases and two of these 6 cases had gastric varices. Of 8 cases with liver cirrhosis, 4 were classified as Child-Pugh class A and 4 as B. Four patients with cirrhosis had concurrent hepatocellular carcinoma including 1 patient who was HBs Ag positive. Etiologies were membranous obstruction in 11 cases and protein C deficiency in 1 case. The main site of obstruction was IVC in 8 and hepatic vein in 4. PTBA was successfully performed in 8 cases of membranous obstruction. During the mean follow-up period of 27.6 months (12-40 months), there were no reobstructions except in 2 cases. The most common cause of Budd-Chiari syndrome in our cases was membranous obstruction of IVC. Percutaneous transluminal balloon angioplasty is a very useful treatment method.

RESULTS: We demonstrate intact cTnI and 9...... degradation products [molecular weight (MW) 12.0-23.5 kDa]. The bands were comparable in MW to degradation fragments in STEMI. Their early rise in intensity, occurring within few minutes after the alcohol injection, emphasizes how susceptible troponin bands are to chemical/ischemic insults. Moreover, two...... additional bands were visible in the PTSMA population. CONCLUSION: This work describes the degradation products of troponin I in HOCM patients undergoing PTSMA. The detected bands appear fast and are similar to degradations following STEMI. This model contributes to our knowledge of the degradation patterns...

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 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 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. Follow-up events in diabetic and non-diabetic groups were 12 (35.3% and 37 (28.5%, respectively (p was not significant. Conclusion: In patients undergoing successful PCI on CTO, diabetes is associated with higher in-hospital adverse events; however diabetes does not affect long term outcomes in these patients.

    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.

    Microalbuminuria (MA) is considered a major risk factor predisposing to cardiovascular morbidity and mortality. Outcomes after percutaneous coronary intervention (PCI) for patients with acute myocardial infarction (AMI) complicated by MA have been well described. However, data regarding admission MA and coronary and myocardial flow are scant. The aims of this study were to evaluate the effects of admission MA on coronary blood flow and prognosis in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary PCI. Did elevated admission microalbuminuria predict poor myocardial blood flow and 6-month mortality in ST-segment elevation myocardial infarction patients undergoing primary percutaneous coronary intervention? A total of 247 patients undergoing primary PCI for STEMI within 12 hours after symptom onset were studied. Patients were divided into 2 groups according to admission urinary albumin extraction rate (UAER): (1) an MA group (UAER 20-200 µg/min), and (2) a normoalbuminuria (NA) group (UAER < 20 µg/min). Microalbuminuria was observed in 108 patients. Univariate analyses showed statistical differences between the NA and MA groups in serum creatine level, plasma glucose level, and peak creatine kinase level on presentation. Thrombolysis In Myocardial Infarction (TIMI) flow grades (TFGs) 0-2 in the MA group were more frequent (9.4% vs 21.2%, P < 0.05) than in the NA group, and corrected TIMI frame count was higher (23.9 ± 18.5 vs 29.8 ± 23.5, P < 0.05). Admission MA was an independent predictor of poor myocardial perfusion (adjusted relative risk: 3.14, 95% confidence interval: 0.99-6.78) and a higher rate of 6-month mortality in STEMI patients undergoing primary PCI (adjusted relative risk: 1.58, 95% confidence interval: 0.74-3.39). Admission MA levels are associated with impaired myocardial flow and poor prognosis in STEMI patients undergoing primary PCI. © 2012 Wiley Periodicals, Inc.

    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

    Cigarette smokers with ST-segment elevation myocardial infarction (STEMI) may present different response to potent antithrombotic therapy compared to nonsmokers. We assessed the impact of smoking status and intracoronary abciximab in patients with STEMI undergoing primary percutaneous coronary...... intervention (PCI). We pooled data from 5 randomized trials comparing intracoronary versus intravenous abciximab bolus in patients undergoing primary PCI. The primary end point was the composite of death or reinfarction at a mean follow-up of 292 ± 138 days. Of 3,158 participants, 1,369 (43.3%) were smokers......, and they had a lower risk of the primary end point in crude, but not in adjusted analyses (hazard ratio [HR] 0.87, 95% confidence interval [CI] 0.63 to 1.21, p = 0.405). Intracoronary versus intravenous abciximab was associated with a significant reduction in the risk of primary end point among smokers (3...

    Cardiac troponin detected by new-generation, highly sensitive assays predicts clinical outcomes among patients with stable coronary artery disease (SCAD) treated medically. The prognostic value of baseline high-sensitivity cardiac troponin T (hs-cTnT) elevation in SCAD patients undergoing elective percutaneous coronary interventions is not well established. This study assessed the association of preprocedural levels of hs-cTnT with 1-year clinical outcomes among SCAD patients undergoing percutaneous coronary intervention. Between 2010 and 2014, 6974 consecutive patients were prospectively enrolled in the Bern Percutaneous Coronary Interventions Registry. Among patients with SCAD (n=2029), 527 (26%) had elevated preprocedural hs-cTnT above the upper reference limit of 14 ng/L. The primary end point, mortality within 1 year, occurred in 20 patients (1.4%) with normal hs-cTnT versus 39 patients (7.7%) with elevated baseline hs-cTnT (P<0.001). Patients with elevated hs-cTnT had increased risks of all-cause (hazard ratio 5.73; 95% confidence intervals 3.34-9.83; P<0.001) and cardiac mortality (hazard ratio 4.68; 95% confidence interval 2.12-10.31; P<0.001). Preprocedural hs-TnT elevation remained an independent predictor of 1-year mortality after adjustment for relevant risk factors, including age, sex, and renal failure (adjusted hazard ratio 2.08; 95% confidence interval 1.10-3.92; P=0.024). A graded mortality risk was observed across higher tertiles of elevated preprocedural hs-cTnT, but not among patients with hs-cTnT below the upper reference limit. Preprocedural elevation of hs-cTnT is observed in one fourth of SCAD patients undergoing elective percutaneous coronary intervention. Increased levels of preprocedural hs-cTnT are proportionally related to the risk of death and emerged as independent predictors of all-cause mortality within 1 year.

    The presence of metabolic syndrome in men with prostate cancer (PCa) undergoing androgen-deprivation therapy (ADT), especially intermittent type, has not been completely evaluated. The aim of this study is to evaluate metabolic syndrome in men with PCa undergoing intermittent ADT. 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.

    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)

    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.

    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)

    Because of recent changes in criteria for coverage for inpatient hospital stays, most nonacute percutaneous coronary intervention (PCI) procedures are reimbursed on an outpatient basis regardless of underlying patient risk. Downstream effects of these changes on the risk profile of patients undergoing outpatient PCI have not been evaluated. Using the American College of Cardiology National Cardiovascular Data Registry's CathPCI Registry, we assessed temporal trends in risk profiles and rates of hospital admission among 999 279 patients undergoing PCI qualifying for outpatient reimbursement. We estimated mortality and bleeding risk using validated models from the registry. From 2009 to 2014, the proportion of outpatients not admitted to a hospital after PCI increased from 32.8% to 66.3% (Prisk for predicted mortality increased significantly from 17.0% to 19.8% during the study period (Prisk for mortality. Among patients undergoing PCI procedures that qualify for outpatient reimbursement, there has been a temporal decrease in postprocedure hospital admission. Concomitantly, the proportion of these outpatients at high risk for mortality has significantly increased over time. These data suggest that current reimbursement classification could be improved by incorporating patient risk to appropriately match the necessary resources to the needed level of care. © 2016 American Heart Association, Inc.

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

    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.

    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.

    Laron syndrome (LS), which can be defined as primary growth hormone resistance or insensitivity, is a rare genetic disease inherited by an autosomal recessive trait. Although it is undistinguishable from growth hormone deficiency, LS has high levels of growth hormone, but insulin-like growth factor (IGF-1) cannot be synthesized. Mecasermin treatment is the only option for the patients who suffer from LS. This study aims to research cardiac findings of children with LS, who receive treatment with mecasermin. The study enrolled five children four males and one female, 4 M/1 F with LS, two of whom were siblings with a mean age of 6.3±2.1 years, a body weight of 13.36±4.74 kg, a height of 88±8.7 cm, and a body mass index (BMI) of 16.47±3.35. Their demographic data were obtained from their family and files. The children received mecasermin via subcutaneous injection at 0.04-0.12 μg/kg doses twice per day. The duration of mecasermin treatment was 8-53 months. All of them were examined clinically by electrocardiogram and echocardiogram. Their cardiac examinations were normal, except for one case, who had systolic murmur at cardiac auscultation. Arrhythmia was not observed on their electrocardiograms. The echocardiograms did not show a significant congenital cardiac anomaly. Their cardiac measure and functions were within normal ranges. The echocardiogram of the child with the murmur showed mitral and tricuspid insufficiency. The Doppler images showed pulmonary hypertension findings. These findings were proven by angiography. The vasoreactivity test results of that patient were negative. No reason could be found for the observed pulmonary hypertension. We diagnosed this finding as a primary pulmonary hypertension and Bosentan therapy was started. In this study, we showed that cardiac findings were consistent with previous studies. To the best of our knowledge, the observed pulmonary hypertension in children with LS, who received treatment with or without mecasermin

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

    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.

    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.

    Full Text Available It is not known whether biomarkers of hemodynamic stress, myocardial necrosis, and renal function might predict adverse outcome in patients undergoing percutaneous repair of severe mitral valve insufficiency. 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

    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.

    Acute coronary syndrome (ACS) is an important cause of mortality and morbidity in the general population. Recent advances in percutaneous coronary intervention (PCI) and optimal medical treatment have helped to improve the prognosis of patients with ACS. The previous reports indicated that women with ACS have a higher risk of adverse outcomes. However, sex differences in clinical outcomes with contemporary coronary revascularization and medical therapy for ACS have not been elucidated. We analyzed data from 676 consecutive patients with ACS (female, n = 166; male, n = 510) who were treated by emergency PCI between 2011 and 2014 at Juntendo Shizuoka Hospital. The patients were grouped according to sex. We defined major adverse cardiovascular events as a composite of all-cause death and ACS recurrence at 1 year and compared rates of major adverse cardiac events (MACE) between the groups. Women were older (75.4 ± 11.0 vs. 66.2 ± 12.2 years) and had a higher rate of multi-vessel disease, chronic kidney disease, and Killip IV at presentation. The cumulative rate of MACE at 1 year was significantly higher among women than men (17.5 vs. 10.2 %, p = 0.02, log-rank test). However, the association between women and a higher risk of MACE was attenuated after adjusting for age (HR 1.25, 95 % CI 0.77-2.00, p = 0.36) and other variables (HR 0.93, 95 % CI 0.36-2.44, p = 0.88). Adjustment for age and other risk factors attenuated sex differences in mid-term clinical outcomes among patients with ACS after emergency PCI.

    This randomized clinical trial compared the effects of adding US-guided percutaneous electrolysis into a program consisting of manual therapy and exercise on pain, related-disability, function and pressure sensitivity in subacromial pain syndrome. Fifty patients with subacromial pain syndrome were randomized into manual therapy and exercise or percutaneous electrolysis group. All patients received the same manual therapy and exercise program, one session per week for 5 consecutive weeks. Patients assigned to the electrolysis group also received the application of percutaneous electrolysis at each session. The primary outcome was Disabilities of the Arm, Shoulder and Hand (DASH). Secondary outcomes included pain, function (Shoulder Pain and Disability Index-SPADI) pressure pain thresholds (PPTs) and Global Rating of Change (GROC). They were assessed at baseline, post-treatment, and 3, and 6 months after treatment. Both groups showed similar improvements in the primary outcome (DASH) at all follow-ups (P=0.051). Subjects receiving manual therapy, exercise, and percutaneous electrolysis showed significantly greater changes in shoulder pain (P0.91) for shoulder pain and function at 3 and 6 months in favour of the percutaneous electrolysis group. No between-groups differences in PPT were found. The current clinical trial found that the inclusion of US-guided percutaneous electrolysis in combination with manual therapy and exercise resulted in no significant differences for related-disability (DASH) than the application of manual therapy and exercise alone in patients with subacromial pain syndrome. Nevertheless, differences were reported for some secondary outcomes such as shoulder pain and function (SPADI). Whether or not these effects are reliable should be addressed in future studies Perspective This study found that the inclusion of US-guided percutaneous electrolysis into a manual therapy and exercise program resulted in no significant differences for disability

    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)

    Full Text Available MitraClip system implantation is used inhigh-risk patients with severe mitral regurgitation.anesthetic management for mitral clip implantation. The study included 34patients scheduled for MitraClip implantations in the catheterization laboratory. An arterial line and central venous line were inserted under local anesthesia before induction. Epinephrine was started before induction and milrinone infusion was started after induction. The anesthetic technique for induction and maintenance was the same for all patients. All patients were hemodynamically stable intra- and postoperatively. The intervention was successful in 33 cases and aborted in one case because of severe posteromedial leaflet tethering. The epinephrine and milrinone were weaned and all patients were extubated, except, one case mortality happened within the first 8 hours postoperatively. Percutaneous mitral valve repair with MitraClip implantation is a successful alternative in high-risk patients with symptomatic severe mitral regurgitation. Starting epinephrine before anesthetic induction and milrinone infusion induction resulted in decreased pulmonary artery pressure, increased ejection fraction and maintained arterial blood pressure during procedure inspite of worse preoperative conditions.

    Elevated serum uric acid (eSUA) was associated with unfavorable outcome in patients with ST-segment elevation myocardial infarction (STEMI). However, the effect of eSUA on myocardial reperfusion injury and infarct size has been poorly investigated. Our aim was to correlate eSUA with infarct size, infarct size shrinkage, myocardial reperfusion grade and long-term mortality in STEMI patients undergoing primary percutaneous coronary intervention. We performed a post-hoc patients-level analysis of two randomized controlled trials, testing strategies for myocardial ischemia/reperfusion injury protection. Each patient underwent acute (3-5 days) and follow-up (4-6 months) cardiac magnetic resonance. Infarct size and infarct size shrinkage were outcomes of interest. We assessed T2-weighted edema, myocardial blush grade (MBG), corrected Thrombolysis in myocardial infarction Frame Count, ST-segment resolution and long-term all-cause mortality. A total of 101 (86.1% anterior) STEMI patients were included; eSUA was found in 16 (15.8%) patients. Infarct size was larger in eSUA compared with non-eSUA patients (42.3 ± 22 vs. 29.1 ± 15 ml, P = 0.008). After adjusting for covariates, infarct size was 10.3 ml (95% confidence interval 1.2-19.3 ml, P = 0.001) larger in eSUA. Among patients with anterior myocardial infarction the difference in delayed enhancement between groups was maintained (respectively, 42.3 ± 22.4 vs. 29.9 ± 15.4 ml, P = 0.015). Infarct size shrinkage was similar between the groups. Compared with non-eSUA, eSUA patients had larger T2-weighted edema (53.8 vs. 41.2 ml, P = 0.031) and less favorable MBG (MBG < 2: 44.4 vs. 13.6%, P = 0.045). Corrected Thrombolysis in myocardial infarction Frame Count and ST-segment resolution did not significantly differ between the groups. At a median follow-up of 7.3 years, all-cause mortality was higher in the eSUA group (18.8 vs. 2.4%, P = 0.028). eSUA may affect myocardial

    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.

    To determine the cost-effectiveness of drug-eluting stents (DES) compared with bare-metal stents (BMS) in patients requiring a percutaneous coronary intervention in France, using a recent meta-analysis including second-generation DES. A cost-effectiveness analysis was performed in the French National Health Insurance setting. Effectiveness settings were taken from a meta-analysis of 117 762 patient-years with 76 randomised trials. The main effectiveness criterion was major cardiac event-free survival. Effectiveness and costs were modelled over a 5-year horizon using a three-state Markov model. Incremental cost-effectiveness ratios and a cost-effectiveness acceptability curve were calculated for a range of thresholds for willingness to pay per year without major cardiac event gain. Deterministic and probabilistic sensitivity analyses were performed. Base case results demonstrated that DES are dominant over BMS, with an increase in event-free survival and a cost-reduction of €184, primarily due to a diminution of second revascularisations, and an absence of myocardial infarction and stent thrombosis. These results are robust for uncertainty on one-way deterministic and probabilistic sensitivity analyses. Using a cost-effectiveness threshold of €7000 per major cardiac event-free year gained, DES has a >95% probability of being cost-effective versus BMS. Following DES price decrease, new-generation DES development and taking into account recent meta-analyses results, the DES can now be considered cost-effective regardless of selective indication in France, according to European recommendations.

    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.

    Patients with diabetes mellitus (DM) are at higher risk for adverse outcomes following percutaneous coronary intervention (PCI). To determine whether outcomes have improved over time, we analyzed data from 2,838 consecutive patients with medically treated DM, including 1,066 patients (37.6%) treated with insulin, in the National Heart, Lung, and Blood Institute Dynamic Registry undergoing PCI registered in waves 1 (1997-1998), 2 (1999), 3 (2001-2002), 4 (2004), and 5 (2006). We compared baseline demographics and 1-year outcomes in the overall cohort and in analyses stratified by recruitment wave and insulin use. Crude mortality rates by chronological wave were 9.5%, 12.5%, 8.9%, 11.6%, and 6.6% (P value(trend) = .33) among those treated with insulin and, respectively, 9.7%, 6.5%, 4.1%, 5.4%, and 4.7% (P value(trend) = .006) among patients treated with oral agents,. The adjusted hazard ratios of death, myocardial infarction (MI), and overall major adverse cardiovascular events (death, MI, revascularization) in insulin-treated patients with DM in waves 2 to 5 as compared with wave 1 were either higher or the same. In contrast, the similar adjusted hazard ratios for oral agent-treated patients with DM were either similar or lower. Significant improvements over time in adverse events by 1 year were detected in patients with DM treated with oral agents. In insulin-treated diabetic patients, despite lower rates of repeat revascularization over time, death and MI following PCI have not significantly improved. These findings underscore the need for continued efforts at optimizing outcomes among patients with DM undergoing PCI, especially those requiring insulin treatment. Copyright © 2011 Mosby, Inc.

    The aim of this study was to evaluate the clinical utility of the new bleeding criteria, proposed by the Bleeding Academic Research Consortium (BARC), compared with the old criteria for determining the action of physicians in contact with bleeding events, after percutaneous coronary intervention (PCI). The BARC criteria were independently associated with an increased risk of 1-year mortality after PCI, and provided a predictive value, in regard to 1-year mortality. The standardized bleeding definitions will be expected to help the physician to correctly analyze the bleeding events, to select an optimal treatment, and to objectively compare the results of multiple trials and registries. All the patients undergoing PCI from June to September 2012 were prospectively enrolled. Patients who experienced a bleeding event were further classified, based on three different bleeding severity criteria: BARC, Thrombolysis In Myocardial Infarction (TIMI), and Global Use of Strategies To Open coronary arteries (GUSTO). The primary outcome was the occurrence of bleeding events requiring interruption of antiplatelet therapy (IAT) by physicians. A total of 376 consecutive patients were included in this study. Total bleeding events occurred in 46 patients (12.2%). BARC type ≥2 bleeding occurred in 30 patients (8.0%); however, TIMI major or minor bleeding, and GUSTO moderate or severe bleeding occurred in 6 (1.6%) and 11 patients (2.9%), respectively. Of the 46 patients, 28 (60.9% of patients) required IAT. On receiver-operating characteristic curve analysis, bleeding defined BARC type ≥2 effectively predicted IAT, with a sensitivity of 89.3%, and a specificity of 98.5% (pdefinition may be a more useful tool for the detection of bleeding with clinical relevance, for patients undergoing PCI.

    Full Text Available Objectives. To investigate the efficacy and safety of perioperative endocrine therapy (PET for patients with Cushing’s syndrome (CS undergoing retroperitoneal laparoscopic adrenalectomy (RLA. Methods. The novel, simplified PET modality of 82 patients who underwent RLA procedures for CS were studied. Clinical manifestations were observed for all patients on days 1 and 5 postoperatively, and clinical data, such as blood pressure (BP, levels of serum cortisol, adrenocorticotropin (ACTH, blood glucose, and electrolytes, were acquired and analyzed. Results. Supraphysiological doses of glucocorticoid were administered during the perioperative period, and the dosage was reduced gradually. In all 82 cases, the RLAs were performed successfully without any perioperative complication, such as steroid withdrawal symptoms. The patient’s symptoms and signs were improved quickly and safely during the hospital days. The serum cortisol and potassium levels were rather stable on days 1 and 5 postoperatively, and most were within the normal range. The clinical manifestations, serum levels of cortisol, ACTH, and potassium in most patients restored to normal gradually after several months (mean, 6.7 ± 1.2 months, except for one patient undergoing bilateral adrenalectomy. Conclusions. This perioperative endocrine therapy for patients with Cushing’s syndrome (mainly for adrenocortical adenoma undergoing retro-laparoscopic adrenalectomy is both effective and safe.

    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.

    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.

    Previous studies explored the association between hemorheological alterations and acute myocardial infarction, pointing out the role of hematological components on microvascular flow. The aim of this study was to evaluate the association between blood viscosity and infarct size, estimated by creatine kinase (CK) peak activity and cardiac Troponin I (cTnI) peak concentration in ST-segment elevation myocardial infarction (STEMI) patients after primary percutaneous coronary intervention (PCI). The study population included 197 patients with diagnosis of STEMI undergoing PCI. Hemorheological studies were performed by assessing whole blood viscosity (measured at shear rates of 0.512 s(-1) and 94.5 s(-1)) and plasma viscosity using the Rotational Viscosimeter LS 30 and erythrocyte deformability index by Myrenne filtrometer. Significant correlations between CK peak activity, cTnI peak concentration, left ventricular ejection fraction and hemorheological variables were observed. At linear regression analysis (adjusted for age, gender, traditional cardiovascular risk factors, renal dysfunction, timeliness of reperfusion, pre-PCI TIMI flow, infarct location, multivessel disease and previous coronary artery disease) leukocytes and whole blood viscosity at 0.512 s(-1) and 94.5 s(-1) were independently and positively associated with infarct size. These results demonstrate a significant and independent association between hemorheology and infarct size in STEMI patients after PCI suggesting that blood viscosity, in a condition of low flow, might worsen myocardial perfusion leading to an increased infarct size. The measurement of whole blood viscosity in STEMI patients could help to identify those who may benefit from new therapeutic strategies.

    Catheter-related bladder discomfort (CRBD) is the most distressing symptom in patients due to intraoperative urinary catheterization. Amikacin significantly inhibits detrusor contraction evoked by prejunctional stimulation. The aim of this study is to evaluate the efficacy of amikacin in prevention of CRBD in patients undergoing percutaneous nephrolithotomy. Study areas were operation theater and postanesthesia care unit of the Department of Anesthesiology, SGPGIMS, Lucknow. One hundred adult patients of either sex were randomly assigned into two groups of fifty each. Patients in control group received normal saline whereas patients in amikacin group received amikacin 10 mg/kg just before induction. Grading of CRBD was done as none, mild, moderate, and severe by a blinded observer at 0, 1, 6, 12, and 24 h after surgery. Data were analyzed using Student's t -test and Chi-square test among groups. Incidence of CRBD was compared with Chi-square test whereas severity was analyzed by the test of proportions (Z-test). Visual analog score was compared using Mann-Whitney U-test for surgical site pain. Incidence of CRBD in control group was 66% as compared to 44% observed in amikacin group ( P < 0.05). During intergroup comparison at different time points, incidence of CRBD was reduced at 1 and 6 h in the amikacin group ( P < 0.05). Significant reduction in the severity of CRBD (moderate) was also observed at 1 h in the amikacin group ( P < 0.05). At rest of the time points, there was no significant difference. Amikacin can significantly reduce the incidence and severity of CRBD in the first few hours after surgery.

    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.

    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.

    The use of bivalirudin versus unfractionated heparin monotherapy in patients without ST-segment-elevation myocardial infarction is not well defined. The study population consisted of patients enrolled in the Evaluation of Drug-Eluting Stents and Ischemic Events (EVENT) registry with either non-ST-segment-elevation acute coronary syndromes or stable ischemic heart disease, who underwent percutaneous coronary intervention with either unfractionated heparin or bivalirudin monotherapy. Propensity score matching was used to adjust for baseline characteristics. The primary bleeding (in-hospital composite bleeding-access site bleeding, thrombolysis in myocardial infarction major/minor bleeding, or transfusion) and primary (in-hospital death/myocardial infarction) and secondary ischemic outcomes (death/myocardial infarction/unplanned repeat revascularization at 12 months) were evaluated. Propensity score matching yielded 1036 patients with non-ST-segment-elevation acute coronary syndromes and 2062 patients with stable ischemic heart disease. For the non-ST-segment-elevation acute coronary syndrome cohort, bivalirudin use was associated with lower bleeding (difference, -3.3% [-0.8% to -5.8%]; P=0.01; number need to treat=30) without increase in either primary (difference, 1.2% [4.1% to -1.8%]; P=0.45) or secondary ischemic outcomes, including stent thrombosis (difference, 0.0% [1.3% to -1.3%]; P=1.00). Similarly, in the stable ischemic heart disease cohort, bivalirudin use was associated with lower bleeding (difference, -1.8% [-0.4% to -3.3%]; P=0.01; number need to treat=53) without increase in either primary (difference, 0.4% [2.3% to -1.5%]; P=0.70) or secondary ischemic outcomes, including stent thrombosis (difference, 0.0% [0.7% to -0.7%]; P=1.00) when compared with unfractionated heparin monotherapy. Among patients with non-ST-segment-elevation acute coronary syndromes or stable ischemic heart disease undergoing percutaneous coronary intervention, bivalirudin use

    The purpose of this study was to compare ultrasound-guided percutaneous tendon fenestration to platelet-rich plasma (PRP) injection for treatment of greater trochanteric pain syndrome. After Institutional Review Board approval was obtained, patients with symptoms of greater trochanteric pain syndrome and ultrasound findings of gluteal tendinosis or a partial tear (Pain scores were recorded at baseline, week 1, and week 2 after treatment. Retrospective clinic record review assessed patient symptoms. The study group consisted of 30 patients (24 female), of whom 50% were treated with fenestration and 50% were treated with PRP. The gluteus medius was treated in 73% and 67% in the fenestration and PRP groups, respectively. Tendinosis was present in all patients. In the fenestration group, mean pain scores were 32.4 at baseline, 16.8 at time point 1, and 15.2 at time point 2. In the PRP group, mean pain scores were 31.4 at baseline, 25.5 at time point 1, and 19.4 at time point 2. Retrospective follow-up showed significant pain score improvement from baseline to time points 1 and 2 (P.99). Our study shows that both ultrasound-guided tendon fenestration and PRP injection are effective for treatment of gluteal tendinosis, showing symptom improvement in both treatment groups. © 2016 by the American Institute of Ultrasound in Medicine.

    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.

    Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are two of the most severe, rare, and life-threatening adverse reactions to medications. Their incidence is approximately two patients per million population per year. Several cases have been reported in the literature in which SJS and TEN have occurred in patients with a neoplasm undergoing radiation therapy and who are taking an anticonvulsant. We report a case of SJS-TEN that developed in a 51-year-old woman with nonresectable non-small-cell lung cancer during treatment with phenobarbital plus radiation therapy for bone metastases but in whom the irradiated areas did not exhibit the SJS skin reaction. To our knowledge, no similar cases have been reported in the literature. (author)

    Full Text Available Background. Polycystic ovarian syndrome (PCOS women undergoing in vitro fertilization and embryo transfer (IVF-ET treatment always attain a low cumulative pregnancy rate disaccording with the satisfactory number of oocytes. Objective. We aim to evaluate the status of coagulation and fibrinolytic system in PCOS patients undergoing controlled ovarian hyperstimulation (COH process. Method. Of the 97 women, 30 patients with PCOS composed the study group; 67 women of child-bearing age with normal endocrine function composed the control group. All participants underwent GnRH agonist standard long protocol, and plasma HCY, FVIII, FX, and D-dimer levels as well as hormone parameters were measured at day of full downregulation, hCG priming, and embryos transfer. Results. On day of full downregulation, FX levels were significantly higher in PCOS group (P<0.01. On hCG priming day, FX and estrogen levels in PCOS group were higher than in the control group and FVIII levels were significantly lower on day of embryos transfer whereas FX and E2 levels were significantly higher in PCOS group. Conclusion. Hypercoagulable state during peri-implantation phase would probably lead to poor microcirculation of endometrium and be one of the most important disadvantages of successful implantation and subsequent clinical pregnancy.

    To determine the predictors of periprocedural blood transfusion and the association of transfusion on outcomes in high risk patients undergoing endoluminal percutaneous vascular interventions (PVI) for peripheral arterial disease. Between 2010-2014 at 47 hospitals participating in a statewide quality registry, 4.2% (n = 985) of 23,273 patients received a periprocedural blood transfusion. Transfusion rates varied from 0 to 15% amongst the hospitals in the registry. Using multiple logistic regression, factors associated with increased transfusion included female gender (OR = 1.9; 95% CI: 1.6-2.1), low creatinine clearance (1.3; 1.1-1.6), pre-procedural anemia (4.7; 3.9-5.7), family history of CAD (1.2; 1.1-1.5), CHF (1.4; 1.2-1.6), COPD (1.2; 1.1-1.4), CVD or TIA (1.2; 1.1-1.4), renal failure CRD (1.5; 1.2-1.9), pre-procedural heparin use (1.8; 1.4-2.3), warfarin use (1.2; 1.0-1.5), critical limb ischemia (1.7; 1.5-2.1), aorta-iliac procedure (1.9; 1.5-2.5), below knee procedure (1.3; 1.1-1.5), urgent procedure (1.7; 1.3-2.2), and emergent procedure (8.3; 5.6-12.4). Using inverse weighted propensity matching to adjust for confounders, transfusion was a significant risk factor for death (15.4; 7.5-31), MI (67; 29-150), TIA/stroke (24; 8-73) and ARF (19; 6.2-57). A focused QI program was associated with a 28% decrease in administration of blood transfusion (p = 0.001) over 4 years. In a large statewide PVI registry, post procedure transfusion was highly correlated with a specific set of clinical risk factors, and with in-hospital major morbidity and mortality. However, using a focused QI program, a significant reduction in transfusion is possible.

    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

    Previous studies have indicated that berberine is an effective insulin sensitizer with comparable activity to metformin (Diabetes 2006, 55, 2256). Reduced insulin sensitivity is reportedly a factor adversely affecting the outcome of IVF in patients with polycystic ovary syndrome (PCOS) (Human Reproduction 2006, 21, 1416). Our objective was to evaluate the clinical, metabolic and endocrine effects of berberine vs metformin in PCOS women scheduled for IVF treatment and to explore the potential benefits to the IVF process. We performed a prospective study in 150 infertile women with PCOS undergoing IVF treatment. Patients were randomized to receive berberine, metformin or placebo tablets for 3 months before ovarian stimulation. The clinical, endocrine, metabolic parameters and the outcome of IVF. Compared with placebo, greater reductions in total testosterone, free androgen index, fasting glucose, fasting insulin and HOMA-IR, and increases in SHBG, were observed in the berberine and metformin groups. Three months of treatment with berberine or metformin before the IVF cycle increased the pregnancy rate and reduced the incidence of severe ovarian hyperstimulation syndrome. Furthermore, treatment with berberine, in comparison with metformin, was associated with decreases in BMI, lipid parameters and total FSH requirement, and an increase in live birth rate with fewer gastrointestinal adverse events. Berberine and metformin treatments prior to IVF improved the pregnancy outcome by normalizing the clinical, endocrine and metabolic parameters in PCOS women. Berberine has a more pronounced therapeutic effect and achieved more live births with fewer side effects than metformin. © 2013 John Wiley & Sons Ltd.

    To assess the long-term cost-effectiveness of 12 months treatment of prasugrel compared to clopidogrel in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) in the Spanish health care system. A Markov state transition model was developed to estimate health outcomes, quality adjusted life years (QALYs), life years (LY), and costs over patients' lifetimes. Clinical inputs were based on an analysis of the TRITON-TIMI 38 clinical trial. Hospital readmissions captured during the trial in a sub-study of patients from eight countries (and subsequent re-hospitalisations modelled to accrue beyond the time horizon of the trial), were assigned to Spanish diagnosis-related group payment schedules to estimate hospitalisation costs. Mean total treatment costs were ?11,427 and ?10,910 for prasugrel and clopidogrel respectively. The mean cost of the study drug was ?538 higher for prasugrel vs. clopidogrel, but rehospitalisation costs at 12 months were ?79 lower for prasugrel due to reduced rates of revascularisation. Hospitalisation costs beyond 12 months were higher with prasugrel by ?55, due to longer life expectancy (+0.071 LY and +0.054 QALYs) associated with the decreased nonfatal myocardial infarction rate in the prasugrel group. The incremental cost per life year and QALY gained with prasugrel was ?7,198, and ?9,489, respectively. Considering a willingness-to-pay threshold of ?30,000/QALY gained in the Spanish setting, prasugrel represents a cost-effective option in comparison with clopidogrel among patients with ACS undergoing PCI.

    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 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 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.

    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.

    Prior percutaneous coronary intervention (PCI) is increasingly encountered in acute coronary syndrome (ACS) patients, with uncertain significance. We sought to evaluate the impact of prior PCI in ACS patients. Patients with ACS enrolled in the prospective PROSPECT registry underwent three-vessel intravascular ultrasound and virtual histology evaluation after successful PCI of the culprit lesion(s). We identified patients with prior PCI (>6 months before index ACS) and compared their outcomes to those without prior PCI. Time-to-event for major adverse cardiac events (MACE) was estimated up to three years, and the independent association between prior PCI and MACE was evaluated in a multivariable model. Among 696 patients enrolled, 77 (11.1%) had prior PCI. They were older and more likely to have prior myocardial infarction, chronic kidney disease, and congestive heart failure. At three years, patients with prior PCI had significantly higher rates of cardiac death, rehospitalisation for worsening angina, and MACE (adjusted HR=1.73 [95% CI: 1.09, 2.75], p=0.02), independent of other comorbidities and intravascular ultrasound findings. Prior PCI was noted in over 10% of patients with ACS and was associated with higher mortality and morbidity, independent of other comorbidities. Prior PCI should be considered a high-risk feature when evaluating ACS patients.

    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.

    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.

  6. 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.

    Background/Purpose. May-Thurner syndrome is an uncommon disease entity in which the left common iliac vein is compressed by the right common iliac artery with subsequent development of deep vein thrombosis and chronic venous insufficiency. We report our experience on the treatment of extensive iliofemoral deep venous thrombosis due to May-Thurner syndrome using endovascular techniques. Methods. The study group comprised 21 patients (8 men, 13 women; mean age 51 years) diagnosed with May-Thurner syndrome by venogram. Eighteen patients were treated with catheter-guided thrombolysis; 3 patients with short segment involvement did not require thrombolysis. After completion of the thrombolytic therapy, the residual venous narrowing was treated by balloon angioplasty and/or placement of a self-expandable stent. Results. The mean total dose of urokinase was 4.28 ± 1.89 million units, and the mean duration of infusion was 72 ± 35 hr. Eighteen of the 21 patients received stent deployment. The mean diameter of the stents was 12.9 ± 2.0 mm. Initial technical successes with immediate symptom resolution were achieved in 20 of the 21 patients (95%). We performed a follow-up venogram 6 months after procedure and checked clinical symptoms at outpatient clinics (mean follow-up duration 10.8 months). Among the patients who received stent implantation, 2 had recurrent thrombotic occlusion during the follow-up period. Three patients, who did not receive stent implantation, all had recurrent thrombosis. There were no major bleeding complications except in 1 patient who developed retroperitoneal hematoma. Conclusion. Catheter-guided thrombolysis and angioplasty with stent implantation is a safe and effective method for the treatment of May-Thurner syndrome

    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.

    Sinusoidal obstruction syndrome, previously known as veno-occlusive disease (VOD/SOS), is a complication in patients undergoing haemopoietic stem cell transplantation (HSCT). Severe VOD/SOS, including progression to multi-organ failure, has resulted in a mortality of greater than 80%. Defibrotide's varying pharmacological actions, particularly on endothelial cells, make it is a useful agent to consider for prophylaxis and treatment of VOD/SOS. Barriers to its routine use include the high acquisition cost and the fact that neither the oral or parenteral formulations are licensed products in many countries at this time. This review summarises available literature on the use of defibrotide in the management of VOD/SOS. Publications consist predominantly of single centre cohort studies and case series. Available evidence indicates that defibrotide is effective in the management of VOD/SOS. Using defibrotide prophylaxis should also be considered, especially in the paediatric setting, where there are available results from a large, open label, randomized controlled trial. Patient outcome data from the larger studies and compassionate programs can inform consensus recommendations on dosing regimen and criteria for the treatment of VOD/SOS with defibrotide in the adult population. The reviewed literature indicates an effective and safe dose for treatment is 25mg/kg/day, continued for at least 14days or until complete response is achieved. Further studies are required to determine the optimal dose and duration of treatment in both paediatric patients and adults. Recent recommendations and a phase 3 trial using historical controls indicate that defibrotide should be included as a pharmacotherapy option in protocols guiding management of VOD/SOS.

    Objective: To study the prognostic risk factors of male patients with coronary heart disease in stent placement era. Methods: One hundred and four patients were enrolled in this study (aged 64.9 ± 9.6 years) including 61 diagnosed as acute myocardial infarction, and 43 as unstable angina with followed up 11.9 ± 8.7 months. All factors including demographic factors, non-interventional work-up, associated clinical complications and results of coronary artery angiography reached a model of Logistic regression analysis. Results: Based on MACE (major adverse cardiac events), as quantitative factors, diseased proximal middle left anterior descending artery was a significant independent variable (P<0.05), and its coefficient was 22.00. Conclusions: Diseased proximal middle left anterior descending coronary artery is the prognostic factor of MACE in male patients with acute coronary syndrome. (authors)

    To investigate the safety of a novel percutaneous circulatory support device during high-risk percutaneous coronary intervention (PCI). The Reitan catheter pump (RCP) consists of a catheter-mounted pump-head with a foldable propeller and surrounding cage. Positioned in the descending aorta the pump creates a pressure gradient, reducing afterload and enhancing organ perfusion. Ten consecutive patients requiring circulatory support underwent PCI; mean age 71 +/- 9; LVEF 34% +/- 11%; jeopardy score 8 +/- 2.3. The RCP was inserted via the femoral artery. Hemostasis was achieved using Perclose sutures. PCI was performed via the radial artery. Outcomes included in-hospital death, MI, stroke, and vascular injury. Hemoglobin (Hb), free plasma Hb (fHb), platelets, and creatinine (cre) were measured pre PCI and post RCP removal. The pump was inserted and operated successfully in 9/10 cases (median 79 min). Propeller rotation at 10,444 +/- 1,424 rpm maintained an aortic gradient of 9.8 +/- 2 mm Hg. Although fHb increased, there was no significant hemolysis (4.7 +/- 2.4 mg/dl pre vs. 11.9 +/- 10.5 post, P = 0.04, reference 20 mg/dl). Platelets were unchanged (pre 257 +/- 74 x 10(9) vs. 245 +/- 63, P = NS). Renal function improved (cre pre 110 +/- 27 micromol/l vs. 99 +/- 28, P = 0.004). The RCP was not used in one patient following femoral introducer sheath related aortic dissection. All PCI procedures were successful with no deaths or strokes, one MI, and no vascular complications following pump removal. The RCP can be used safely in high-risk PCI patients. This device may be an alternative to other percutaneous systems when substantial cardiac support is needed. (c) 2009 Wiley-Liss, Inc.

    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

    This study sought to determine the effect of radial access on outcomes in women undergoing percutaneous coronary intervention (PCI) using a registry-based randomized trial. Women are at increased risk of bleeding and vascular complications after PCI. The role of radial access in women is unclear. Women undergoing cardiac catheterization or PCI were randomized to radial or femoral arterial access. Data from the CathPCI Registry and trial-specific data were merged into a final study database. The primary efficacy endpoint was Bleeding Academic Research Consortium type 2, 3, or 5 bleeding or vascular complications requiring intervention. The primary feasibility endpoint was access site crossover. The primary analysis cohort was the subgroup undergoing PCI; sensitivity analyses were conducted in the total randomized population. The trial was stopped early for a lower than expected event rate. A total of 1,787 women (691 undergoing PCI) were randomized at 60 sites. There was no significant difference in the primary efficacy endpoint between radial or femoral access among women undergoing PCI (radial 1.2% vs. 2.9% femoral, odds ratio [OR]: 0.39; 95% confidence interval [CI]: 0.12 to 1.27); among women undergoing cardiac catheterization or PCI, radial access significantly reduced bleeding and vascular complications (0.6% vs. 1.7%; OR: 0.32; 95% CI: 0.12 to 0.90). Access site crossover was significantly higher among women assigned to radial access (PCI cohort: 6.1% vs. 1.7%; OR: 3.65; 95% CI: 1.45 to 9.17); total randomized cohort: (6.7% vs. 1.9%; OR: 3.70; 95% CI: 2.14 to 6.40). More women preferred radial access. In this pragmatic trial, which was terminated early, the radial approach did not significantly reduce bleeding or vascular complications in women undergoing PCI. Access site crossover occurred more often in women assigned to radial access. (SAFE-PCI for Women; NCT01406236). Copyright © 2014 American College of Cardiology Foundation. Published by Elsevier Inc

    It is unknown which definition of contrast-induced acute kidney injury (CI-AKI) in the setting of percutaneous coronary interventions is best associated with inpatient mortality and whether this association is stable across patients with various preprocedural serum creatinine (SCr) values. We applied logistic regression models to multiple CI-AKI definitions used by the Kidney Disease Improving Global Outcomes guidelines and previously published studies to examine the impact of preprocedural SCr on a candidate definition's correlation with the adverse outcome of inpatient mortality. We used likelihood ratio tests to examine candidate definitions and identify those where association with inpatient mortality remained constant regardless of preprocedural SCr. These definitions were assessed for specificity, sensitivity, and positive and negative predictive values to identify an optimal definition. Our study cohort included 119,554 patients who underwent percutaneous coronary intervention in Michigan between 2010 and 2014. Most commonly used definitions were not associated with inpatient mortality in a constant fashion across various preprocedural SCr values. Of the 266 candidate definitions examined, 16 definition's association with inpatient mortality was not significantly altered by preprocedural SCr. Contrast-induced acute kidney injury defined as an absolute increase of SCr ≥0.3 mg/dL and a relative SCr increase ≥50% was selected as the optimal candidate using Perkins and Shisterman decision theoretic optimality criteria and was highly predictive of and specific for inpatient mortality. We identified the optimal definition for CI-AKI to be an absolute increase in SCr ≥0.3 mg/dL and a relative SCr increase ≥50%. Further work is needed to validate this definition in independent studies and to establish its utility for clinical trials and quality improvement efforts. Copyright © 2016 Elsevier Inc.

    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.

    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.

    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)

    Full Text Available Freeman-Sheldon syndrome (FSS or “whistling face” syndrome is a rare congenital disorder complicated by characteristic facial deformities and muscular contractures. We report on a 64-year-old male patient presenting for surgical replacement of his aortic valve and review the available literature on anesthetic considerations and perioperative management principles. FSS frequently poses a significant challenge to airway management and gaining vascular access. Moreover, these patients are reportedly at risk for developing malignant hyperthermia (MH or neuroleptic malignant syndrome.

    Full Text Available Bartter′s syndrome is an unusual (estimated incidence is 1.2 per million people but important congenital form of secondary hyperaldosteronism; due to abnormalities in renal handling of electrolytes. It is associated with hypertrophy and hyperplasia of the juxtaglomerular cells, normal blood pressure, and hypokalemic alkalosis withoutedema.We present a 22-year-old woman with Bartter′s syndrome underwent bilateral sagittal split osteotomy to correct mandibular prognathic. The anesthetic management of Bartter′s syndrome should be relevant to the pathophysiology of the syndrome. Therefore, it should be directed toward maintaining cardiovascular stability, control of associated fluid, electrolyte and acid-base derangements, and the prevention of renal damage.

    Few data are available regarding the optimal management of ST-elevation myocardial infarction patients with clinically defined spontaneous reperfusion (SR). We report on the characteristics and outcomes of patients with SR in the primary percutaneous coronary intervention era, and assess whether immediate reperfusion can be deferred. Data were drawn from a prospective nationwide survey, ACSIS (Acute Coronary Syndrome Israeli Survey). Definition of SR was predefined as both (1) ≥70% reduction in ST-segment elevation on consecutive ECGs and (2) ≥70% resolution of pain. Of 2361 consecutive ST-elevation-acute coronary syndrome patients in Killip class 1, 405 (17%) were not treated with primary reperfusion therapy because of SR. Intervention in SR patients was performed a median of 26 hours after admission. These patients were compared with the 1956 ST-elevation myocardial infarction patients who underwent primary reperfusion with a median door-to-balloon of 66 minutes (interquartile range 38-106). Baseline characteristics were similar except for slightly higher incidence of renal dysfunction and prior angina pectoris in SR patients. Time from symptom onset to medical contact was significantly greater in SR patients. Patients with SR had significantly less in-hospital heart failure (4% versus 11%) and cardiogenic shock (0% versus 2%) ( P <0.01 for all). No significant differences were found in in-hospital mortality (1% versus 2%), 30-day major cardiac events (4% versus 4%), and mortality at 30 days (1% versus 2%) and 1 year (4% versus 4%). Patients with clinically defined SR have a favorable prognosis. Deferring immediate intervention seems to be safe in patients with clinical indices of spontaneous reperfusion. © 2017 The Authors.

    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.

    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.

    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.

    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.)

    Full Text Available BACKGROUND Coronary heart disease has become an epidemic since 20th century. Deaths due to the same are increasing of around 17.5 million deaths in year 2012. The deaths are increasing more in developing countries and metabolic syndrome is a cluster of disorders, which are promoting the development of coronary artery diseases. The disorders include central obesity, insulin resistance, dyslipidaemia and hypertension. Increasing prevalence, changing lifestyle and progression of the disease without obvious symptoms had led to increasing morbidity and mortality. The non-infectious epidemic of the century is posing great challenges to healthcare and research in development of more infrastructure and funds to prevent and treat the disease. MATERIALS AND METHODS A total of 100 patients diagnosed with CAD and posted for Coronary Angiogram (CAG in ICCU at KIMS Hospital, Hubballi, were studied over a period of one and a half year. Cases were categorised according to ATPIII and new IDF criteria for metabolic syndrome and compared. Clinical evaluation, ECG, lipid profile and 2D-echo was done. Statistical analysis done using unpaired t-test, Mann-Whitney tests, Chi-square test and Kappa statistics. RESULTS Of the total 100, 57 had metabolic syndrome by either ATP criteria or IDF criteria. Kappa=0.859 (p-value 150 mg/dL and DM or FBS >100 mg/dL (p value <0.001. The mean values of SBP (144.0 vs. 120.8, DBP (85.6 vs. 73.8 and waist circumference (95.4 vs. 87.7 was statistically significant (p value <0.01 between patients with metabolic syndrome and without metabolic syndrome with IDF criteria (p value <0.001. It was observed LAD (28.1% was the most common vessel involved individually. There was no much significance related to metabolic syndrome. Incidence of CAD was more common in patients with metabolic syndrome than other group. CONCLUSION The prevalence of metabolic syndrome was high in patients with CAD.

    Full Text Available Eisenmenger′s syndrome is a cyanotic congenital heart disease that includes pulmonary hypertension with reversed or bidirectional shunt associated with septal defects or patent ductus arteriosus. The decreased systemic vascular resistance associated with pregnancy increases the degree of right to left shunting, thereby carrying substantial risk to both the mother and the foetus. The maternal mortality rate of pregnancy in the presence of Eisenmenger′s syndrome is reported to be as high as 30-70%. We present a case of a 22-year-old primigravida with Eisenmenger′s syndrome who gave birth at 37 weeks of gestation via caesarean section to a live female baby under general anaesthesia. On the third post-operative day, the patient developed tachycardia, tachypnoea, hypotension and decrease in oxygen saturation despite supplemental oxygen, clinically suspected pulmonary thromboembolism. We describe the anaesthetic management for caesarean section and its complications in a patient with Eisenmenger′s syndrome. Although pregnancy should be discouraged in women with Eisenmenger′s syndrome, it can be successful.

    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.

    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.

    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 < 0.0001). High CONUT scores showed a significant increase in the incidence of MACE compared with low CONUT scores, even after adjusting for confounding factors (hazard ratio: 1.64, 95% confidence interval 1.30-2.07, p < 0.0001). Adding CONUT scores to a baseline model with established risk factors improved the C-index (p = 0.02), net reclassification improvement (p = 0.004) and integrated discrimination improvement (p = 0.0003). 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.

    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.

    Full Text Available ABSTRACT Introduction 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. Materials and Methods 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. Results 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. Conclusion This study demonstrates the effectiveness of PTNS and ES with PFMT in women with OAB, but greater improvements were found with PTNS.

    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.

    This study aimed to evaluate the effect of methylprednisolone on prevention of ovarian hyperstimulation syndrome (OHSS) in polycystic ovarian syndrome (PCOS) patients undergoing in-vitro fertilisation (IVF). This randomised controlled trial was carried out between November 2009 and December 2013. A total of 219 eligible patients were randomly allocated for treatment (n = 108) or control groups (n = 111). The treatment group received oral methylprednisolone starting from the first day of stimulation. These patients also received an intravenous dose of methylprednisolone on the days of egg collection and embryo transfer. The control group received no glucocorticoid treatment to prevent OHSS. Nineteen percent of patients (18/93) who received methylprednisolone developed OHSS compared with 16.5% (15/91) in the control group and no significant difference was found (p = .61). There were no significant differences between treatment and control groups in the rates of implantation (10% versus 11%, p = .77) and clinical pregnancy (23.2% versus 17.7%, p = .46). Methylprednisolone did not reduce the incidence and severity of OHSS in PCOS patients undergoing IVF and no improvement in clinical outcomes was observed. Impact statement No significant differences were found in OHSS incidence and clinical outcomes between women who received methylprednisolone and control group. There seems to be no benefit for the routine use of glucocorticoids in IVF/ICSI treatments.

    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.

    Full Text Available Jennifer Vergara-Jimenez, Pierluigi TricociDepartment of Medicine-Cardiology, Duke Clinical Research Institute, Durham, North Carolina, USAAbstract: Abciximab is a widely studied glycoprotein IIb/IIIa inhibitor, specifically in the setting of patients undergoing percutaneous coronary intervention (PCI. The populations studied have included patients with non-ST-segment acute coronary syndromes, ST-segment elevation myocardial infarction, and elective PCI. This large amount of information provides a clear efficacy and safety profile of the drug, although a few questions on the use of abciximab still exist, particularly on its use and preference in the setting of newer antiplatelet and antithrombotic medications. In this article we review the most relevant data from randomized clinical trials with abciximab in patients undergoing PCI and discuss the recent guideline recommendation on use during PCI.Keywords: abciximab, percutaneous coronary intervention, glycoprotein inhibitor

    To determine whether there is a difference in 2-year prognosis among patients across the spectrum of coronary artery disease undergoing percutaneous coronary intervention (PCI). We analyzed all consecutive patients undergoing PCI at a single center from 1/1-12/31/2013. Clinical presentations were compared between sexes according to baseline clinical, angiographic, and procedural characteristics and 2-year (mean 730 ± 30-day) outcomes. We grouped 10 724 consecutive patients based on sex and clinical presentation. Among patients with ST-elevation myocardial infarction (STEMI), rates of all-cause death (6.7% vs 1.4%) and cardiac death (3.8% vs 1.1%) were significantly higher in women than in men (P presenting with ACS. After multivariable adjustment, female sex was not an independent predictor of outcomes in STEMI (hazard ratio [HR] for all-cause death: 1.33, 95% confidence interval [CI]:0.52-3.38; P = 0.55; HR for cardiac death: 0.69, 95%CI: 0.23-2.09, P = 0.51], but was still an independent predictor of bleeding in STEMI (HR: 3.53, 95%CI: 1.26-9.91, P = 0.017). Among STEMI patients, women had worse 2-year mortality after PCI therapy, but female sex was not an independent predictor of mortality after adjustment for baseline characteristics. In STEMI patients, women were at higher bleeding risk than men after PCI, even after multivariable adjustment. © 2017, Wiley Periodicals, Inc.

    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.

    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.

    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 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 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.

    Since older age is a strong predictor of not only bleeding but also of ischemic events, understanding the risk:benefit profile of bivalirudin in the elderly undergoing primary percutaneous coronary intervention (pPCI) for ST-segment elevation (STEMI) is important. For this, we aim to compare elderly with young patients, who all underwent pPCI for STEMI and randomly received either bivalirudin or heparin. We performed a patient-level pooled analysis (n=5800) of two large randomized trials. A total of 2149 (37.1%) elderly patients (>65 years of age) with STEMI were enrolled and randomly assigned to either bivalirudin or heparin with or without a GPI (control group) before pPCI. Clinical outcomes at 30 days were analyzed. In elderly patients, bivalirudin significantly reduced non-CABG major bleeding (7.1% vs 10.4%; PST (0.4% vs 1.5%; PST, or all-cause death, when compared with heparin with or without GPI. In a large group of elderly patients enrolled in the EUROMAX and HORIZONS-AMI trials, bivalirudin was associated with lower 30-day rates of non-CABG major bleeding, subacute ST and NACE, with similar 30-day rates of acute ST and mortality.

    2003-09-01

    Percutaneous tracheostomy is safe and highly effective in well-trained hands in establishing a long-term artificial airway. Most alleged contraindications and some suggestions on how the procedures should be performed likely stem from early trials when only "perfect candidates" were chosen. Most of those contraindications should not be viewed as prohibitions, but as suggestions related to the skill level and training of the operator. We have used this technique in many situations where the small incision and tamponading effect of the tracheostomy tube has been quite beneficial, in selected patients with coagulapathies and severe venous congestion from superior cava syndromes as well as thyroid cancers, and in whom operative approaches would have been difficult. Knowing one's level of expertise and comfort in choosing and rejecting patients and procedures accordingly is the key to keeping PT a procedure with an excellent safety record. As the experience with PT grows, more and more perceived contraindications will disappear. Studies will address the role of PT in children and as a means of establishing emergent airway access. Also, the exact coagulation limits will need to be established. Few contraindications will most likely remain absolute, such as active infections over the proposed entry site, uncontrollable bleeding disorders and excessive ventilatory and oxygenation requirements. In our institution, taking into account these absolute contraindications, fewer than 5% of patients in need of a tracheostomy in the intensive care unit will undergo a primary open procedure.

    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.

    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.

    Elevated heart rate (HR) is associated with mortality in a number of heart diseases. We examined the long-term prognostic significance of HR at discharge in a contemporary population of patients with stable angina (SAP), non-ST-segment elevation acute coronary syndromes (NSTE-ACS), and ST-segment elevation myocardial infarction (STEMI) revascularized with percutaneous coronary intervention (PCI). Patients from the BASKET-PROVE trial, an 11-center randomized all-comers trial comparing bare-metal and drug-eluting stenting in large coronary vessels, were included. Discharge HR was determined from a resting ECG. Long-term outcomes (7 days to 2 years) were evaluated for all-cause mortality and cardiovascular death and non-fatal myocardial infarction. A total of 2029 patients with sinus rhythm were included, 722 (35.6%) SAP, 647 (31.9%) NSTE-ACS, and 660 (32.5%) STEMI. Elevated discharge HR was associated significantly with all-cause mortality: when compared to a reference of 90 bpm. For cardiovascular death/myocardial infarction, a discharge HR >90 bpm was associated with a hazard ratio of 6.2 (2.5-15.5, pacute coronary syndromes an elevated discharge HR was independently associated with poor prognosis. Conversely, a HR <60 bpm at discharge was associated with a good long-term prognosis irrespective of indication for PCI. © 2013.

    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.

    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

    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

    The number of patients with atrial fibrillation undergoing percutaneous coronary intervention (PCI) is increasing. Since these patients have a CHA 2 DS 2 -VASc score of 1 or higher, they should be treated with oral anticoagulation to prevent stroke. However, combination therapy with oral anticoagulation for prevention of embolic stroke and dual platelet inhibition for prevention of coronary thrombosis significantly increases bleeding complications. The optimal combination, intensity and duration of antithrombotic combination therapy is still not known. In the rather small randomized WOEST trial, the combination of a vitamin K antagonist (VKA) and clopidogrel decreased bleeding compared to the conventional triple therapy with VKA, clopidogrel and aspirin. In the PIONEER AF-PCI trial, two rivaroxaban-based treatment regimens significantly reduced bleeding complications compared to conventional triple therapy without increasing embolic or ischemic complications following PCI. Dual therapy with rivaroxaban and clopidogrel appeared to provide an optimal risk-benefit ratio. In the RE-DUAL PCI trial, dual therapy with dabigatran also reduced bleeding complications compared to conventional triple therapy. With respect to the composite efficacy end point of thromboembolic events (myocardial infarction, stroke, or systemic embolism), death, or unplanned revascularization dabigatran-based dual therapy was non-inferior to VKA-based triple therapy. The upcoming trials AUGUSTUS with apixaban and ENTRUST-PCI with edoxaban will further examine the use of NOACs in this setting. While recent guidelines recommend NOAC-based dual therapy in only a subset of patients (those who are at increased risk of bleeding), the available data now suggest that this should be the preferred choice for the majority of patients. Adding aspirin to this primary choice for up to 4 weeks in patients at especially high ischemic risk would likely prevent atherothrombotic events, but this needs further

    This study aimed to evaluate the effect of prolonged full-dose bivalirudin infusion in real-world population with ST-elevation myocardial infarction (STEMI). Subgroup data as well as meta-analysis from randomized clinical trials have shown the potency of postprocedural full-dose infusion (1.75 mg/kg/h) of bivalirudin on attenuating acute stent thrombosis (ST) after primary percutaneous coronary intervention (PCI). In this multicenter retrospective observational study, 2047 consecutive STEMI patients treated with bivalirudin during primary PCI were enrolled in 65 Chinese centers between July 2013 and May 2016. The primary outcome was acute ST defined as ARC definite/probable within 24 hours after the index procedure, and the secondary endpoints included total ST, major adverse cardiac or cerebral events (MACCE, defined as death, reinfarction, stroke, and target vessel revascularization), and any bleeding at 30 days. Among 2047 STEMI patients, 1123 (54.9%) were treated with postprocedural bivalirudin full-dose infusion (median 120 minutes) while the other 924 (45.1%) received low-dose (0.25 mg/kg/h) or null postprocedural infusion. A total of three acute ST (0.3%) occurred in STEMI patients with none or low-dose prolonged infusion of bivalirudin, but none was observed in those treated with post-PCI full-dose infusion (0.3% vs 0.0%, P=.092). Outcomes on MACCE (2.1% vs 2.7%, P=.402) and total bleeding (2.1% vs 1.4%, P=.217) at 30 days showed no significant difference between the two groups, and no subacute ST was observed. Post-PCI full-dose bivalirudin infusion is safe and has a trend to protect against acute ST in STEMI patients undergoing primary PCI in real-world settings. © 2017 John Wiley & Sons Ltd.

    2013-10-01

    Myelodysplastic syndromes (MDS) include a group of hematopoietic malignancies characterized by dysplastic changes, ineffective hematopoiesis and variable risk of leukemic progression. At diagnosis, 86% of MDS patients are ≥60 years. Azacitidine, the only drug that prolongs life in high-risk (HR)-MDS patients, adds a median of only 9.5 months to life. Allogeneic stem cell transplantation (alloSCT) remains the only potentially curative approach. Despite recent improvements including use of reduced intensity conditioning (RIC) that decrease transplant-related mortality, alloSCT continues to be used rarely in elderly MDS. There is paucity of data regarding outcomes of RIC alloSCT in elderly MDS patients, especially in direct comparison with azanucleosides. In this paper, the authors discuss the recent Markov decision analysis by Koreth et al. in which investigators demonstrated superior survival of patients with HR-MDS aged 60-70 years who underwent RIC alloSCT in comparison with those who were treated with azanucleosides.

    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.

    Abstract Rationale: Sugammadex is a cylodextrin derivate that encapsulates steroidal neuromuscular blocker agents and is reported as a safe and well-tolerated drug. In this case report, we present a patient who developed grade 3 anaphylaxis just after sugammadex administration. Patient concerns: A 22-year-old woman with diagnosis of Weaver syndrome was scheduled for bilateral mammoplasty and resection of unilateral accessory breast tissue resection. Anesthesia was induced and maintained by propofol, rocuronium, and remifentanil. At the end of the operation, sugammadex was administered and resulted in initially hypotension and bradycardia then the situation worsened by premature ventricular contraction and bigeminy with tachycardia, bronchospasm, and hypoxia. Diagnosis: The Ring and Messmer clinical severity scale grade 3 anaphylactic reaction occurred just after sugammadex injection and the patient developed prolonged hypotension with recurrent cardiac arrhythmias in postoperative 12 hours. Interventions: Treatment was initiated bolus injections of ephedrine, epinephrine, lidocaine, steroids and antihistaminic and continued with lidocaine bolus dosages and norepinephrine infusion for the postoperative period. Outcomes: The general condition of the patient improved to normal 3 hours after the sugammadex injection, and she was moved to the intensive care unit. At 2nd and 8th hours of intensive care unit follow-up, she developed premature ventricular contraction and bigeminy with the heart rate of 130 to 135 beats/min, which returned to sinus rhythm with 50 mg lidocaine. After that, no symptoms were observed and the patient was discharged to plastic surgery clinic at the following day. Lessons: Sugammadex may result in life-treating anaphylactic reaction even in a patient who did not previously expose to drug. Moreover, prolonged cardiovascular collapse and cardiac arrhythmias may occur. PMID:29505006

    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.

    From March 87 to March 92, fifty eight patients were referred to our department for percutaneous endoscopic gastrostomy (PEG). The modality of the feeding tube insertion is described. The most common indications for placement were neurologic disorders in 62% of the cases (n = 36) and malignant diseases in 32% (n = 19). The success rate of the technique was 98.3% (n = 57). No procedure-related mortality was observed. A low rate of major complication (1.7%) and minor complication (10.5%) was noted. Feeding tubes were removed in 21% of patients (n = 12); none of them with malignant disease. Survival curve analysis demonstrated that 50% of patients died within 3 months of PEG placement. Such results raise questions about the selection of patients undergoing PEG. Our experience of patients undergoing PEG. Our experience suggests that PEG is easy and safe, even in debilitated patients, having an acceptable life expectancy.

    Acute coronary syndromes (ACSs) are life-threatening conditions associated with acute myocardial ischaemia. There are three main types of ACS: ST segment elevation myocardial infarction (STEMI), non-ST segment elevation myocardial infarction (NSTEMI) and unstable angina (UA). One treatment for ACS is percutaneous coronary intervention (PCI) plus adjunctive treatment with antiplatelet drugs. Dual therapy antiplatelet treatment [aspirin plus either prasugrel (Efient(®), Daiichi Sankyo Company Ltd UK/Eli Lilly and Company Ltd), clopidogrel or ticagrelor (Brilique(®), AstraZeneca)] is standard in UK clinical practice. Prasugrel is the focus of this review. The remit is to appraise the clinical effectiveness and cost-effectiveness of prasugrel within its licensed indication for the treatment of ACS with PCI and is a review of National Institute for Health and Care Excellence technology appraisal TA182. Four electronic databases (MEDLINE, EMBASE, The Cochrane Library, PubMed) were searched from database inception to June 2013 for randomised controlled trials (RCTs) and to August 2013 for economic evaluations comparing prasugrel with clopidogrel or ticagrelor in ACS patients undergoing PCI. Clinical outcomes included non-fatal and fatal cardiovascular (CV) events, adverse effects of treatment and health-related quality of life (HRQoL). Cost-effectiveness outcomes included incremental cost per life-year gained and incremental cost per quality-adjusted life-year (QALY) gained. An independent economic model assessed four mutually exclusive subgroups: ACS patients treated with PCI for STEMI and with and without diabetes mellitus and ACS patients treated with PCI for UA or NSTEMI and with and without diabetes mellitus. No new RCTs were identified beyond that reported in TA182.

    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

    The study was to access the association between resting heart rate (RHR) and one-year risk of major adverse cardiovascular events (MACE) in acute coronary syndrome (ACS) patients after percutaneous coronary intervention (PCI). Patients with ACS after PCI (n = 808) were prospectively followed-up for MACE. RHR was obtained from electrocardiogram. MACE was defined as a composite of cardiac death, nonfatal recurrent myocardial infarction, ischemic-driven revascularization, and ischemic stroke. The association between RHR and one-year risk of MACE was assessed using Cox proportional hazards regression model. Compared with patients with RHR >76 bpm, the adjusted hazard ratio (AHR) was 0.51 (95% confidence intervals [CI]: 0.23-1.14; P = 0.100) for patients with RHR 76 bpm were at higher risk of MACE during one-year follow-up compared with patients with RHR 61-76 bpm. An elevated RHR ≥ 61 bpm was associated with increased risk of one-year MACE in ACS patients. © 2015 by the Society for Experimental Biology and Medicine.

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

    Full Text Available Central anticholinergic syndrome (CAS following general anesthesia (GA is a well known syndrome in children and adults. Many cases of CAS have been previously reported in the literature. However, there are only two reports of post resuscitation CAS after administration of small doses of atropine. Hereby, we report a case of CAS in a child undergoing complete dental restoration under GA after receiving a small dose of atropine to reverse hypoxia induced bradycardia. Intraoperative events such as hypoxia or cardiac arrest may play a role as triggers for CAS. However, we cannot establish a causal relationship between the occurrence of CAS and such critical events.

    Central anticholinergic syndrome (CAS) following general anesthesia (GA) is a well known syndrome in children and adults. Many cases of CAS have been previously reported in the literature. However, there are only two reports of post resuscitation CAS after administration of small doses of atropine. Hereby, we report a case of CAS in a child undergoing complete dental restoration under GA after receiving a small dose of atropine to reverse hypoxia induced bradycardia. Intraoperative events such as hypoxia or cardiac arrest may play a role as triggers for CAS. However, we cannot establish a causal relationship between the occurrence of CAS and such critical events.

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

    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.

    Previous studies suggest the higher the red blood cell distribution width (RDW) the greater the risk of mortality in patients with coronary artery disease (CAD). However, the relationship between RDW and long-term outcome in CAD patients undergoing percutaneous coronary intervention (PCI) with a drug-eluting stent (DES) remains unclear. This study was designed to evaluate the long-term effect of RDW in patients treated with drug-eluting stent for CAD. In total of 2169 non-anemic patients (1468 men, mean age 60.2 ± 10.9 years) with CAD who had undergone successful PCI and had at least one drug-eluting stent were included in this study. Patients were grouped according to their baseline RDW: Quartile 1 (RDW<12.27%), Quartile 2 (12.27% ≤ RDW <13%), Quartile 3 (13% ≤ RDW<13.5%), and Quartile 4 (RDW ≥ 13.5). The incidence of in-hospital mortality and death or myocardial infarction was significantly higher in Quartiles 3 and 4 compared with Quartile 1 (P<0.05). After a follow-up of 29 months, the incidence of all-cause death and stent thrombosis in Quartile 4 was higher than in Quartiles 1, 2, and 3 (P<0.05). The incidence of death/myocardial infarction/stroke and cardiac death in Quartile 4 was higher than in Quartiles 1 and 2 (P<0.05). Multivariate Cox regression analysis showed that RDW was an independent predictor of all-cause death (hazard ratio (HR) = 1.37, 95% confidence interval (CI) = 1.15-1.62, P<0.001) and outcomes of death/myocardial infarction/stroke (HR = 1.21, 95% CI = 1.04-1.39, P = 0.013). The cumulative survival rate of Quartile 4 was lower than that of Quartiles 1, 2, and 3 (P<0.05). High RDW is an independent predictor of long-term adverse clinical outcomes in non-anemic patients with CAD treated with DES.

    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.

    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.

    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

    Children with congenital heart disease often undergo heart surgery at a young age. They are at risk for postoperative low cardiac output syndrome (LCOS) or death. Milrinone may be used to provide inotropic and vasodilatory support during the immediate postoperative period. This review examines the effectiveness of prophylactic postoperative use of milrinone to prevent LCOS or death in children having undergone surgery for congenital heart disease. Electronic and manual literature searches were performed to identify randomised controlled trials. We searched CENTRAL, MEDLINE, EMBASE and Web of Science in February 2014 and conducted a top-up search in September 2014 as well as clinical trial registries and reference lists of published studies. We did not apply any language restrictions. Only randomised controlled trials were selected for analysis. We considered studies with newborn infants, infants, toddlers, and children up to 12 years of age. Two review authors independently extracted data according to a pre-defined protocol. We obtained additional information from all study authors. Three of the five included studies compared milrinone versus levosimendan, one study compared milrinone with placebo, and one compared milrinone verus dobutamine, with 101, 242, and 50 participants, respectively. Three trials were at low risk of bias while two were at higher risk of bias. The number and definitions of outcomes were non-uniform as well. In one study comparing two doses of milrinone and placebo, there was some evidence in an overall comparison of milrinone versus placebo that milrinone lowered risk for LCOS (risk ratio (RR) 0.52, 95% confidence interval (CI) 0.28 to 0.96; 227 participants). The results from two small studies do not provide enough information to determine whether milrinone increases the risk of LCOS when compared to levosimendan (RR 1.22, 95% CI 0.32 to 4.65; 59 participants). Mortality rates in the studies were low, and there was insufficient evidence to

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

    Objective: To investigate the clinical effect of mechanical aspiration thrombectomy with adjunctive PTA and stenting for iliac vein compression syndrome with lower extremity deep venous thrombosis. Materials and Methods: The clinical data of 184 patients who had iliac vein compression syndrome with lower extremity DVT were analyzed retrospectively. The healthy femoral vein was accessed, then a 12-14 F sheath was introduced via a guide wire to aspirate thrombus in the iliofemoral; For the cases with femoropopliteal thrombus, the thrombus was macerated and pulled by Fogarty balloon catheter, then performing mechanical aspiration thrombectomy. After thrombus removal, PTA and stenting were performed on stenosis or occlusion of common iliac vein that displayed on venography. Results: The thrombus removal rate: Grade Ⅲ 80.89% and Grade Ⅱ 19.02%. The circumference of affected limbs at 15 cm above and below knee joints were (43.9±4.7) cm and (31.5±4.1) cm, respectively, after being discharged from hospital, the differences were statistical significance (t=6.43, t=-5.79, both P=0.000)compared to be hospitalized. The follow -up result: the treatment efficiency was 97.75%. The stent patency rate of postoperation at 6, 12, and 24 months were 97.19%, 94.94%, 92.13%, respectively, on sonography or digital subtract angiography. Conclusion: Mechanical aspiration thrombectomy with adjunctive venoplasty for iliac vein compression syndrome with lower extremity deep venous thrombosis is an effective and safe therapy having notable therapeutic effect in short l middle-term follow-up and shorter hospitalization time.

    The CHA2DS2-VASC score, used for embolic risk stratification in atrial fibrillation (AF), has been reported recently to predict adverse clinical outcomes in patients with acute coronary syndrome (ACS), regardless of having AF. We investigated the correlation between the CHA2DS2-VASC score and contrast-induced nephropathy (CIN) in patients with ACS who underwent urgent percutaneous coronary intervention (PCI). A total of 1,408 patients were enrolled in the study. The CHA2DS2-VASC score was calculated for each patient. Based on the receiver operating characteristic analysis, the study population was divided into 2 groups: CHA2DS2-VASC score ≤3 group (n = 944) and CHA2DS2-VASC score ≥4 group (n = 464). Patients were then reallocated to 2 groups according to the presence or absence of CIN. CIN was defined as a rise in serum creatinine >0.5 mg/dl or >25% increase in baseline within 72 hours after PCI. Overall, 159 cases (11.3%) of CIN were diagnosed. Receiver operating characteristic curve analysis revealed good diagnostic value of CHA2DS2-VASC score in predicting CIN (area under the curve 0.769, 95% confidence interval 0.733 to 0.805; p high score had a higher frequency of CIN (23.9% vs 5.1%; p <0.001), and multivariate analysis identified the CHA2DS2-VASC score of ≥4 as an independent predictor of CIN. In conclusion, CHA2DS2-VASC score can be used as a new, simple, and reliable tool to predict CIN in patients with ACS who underwent urgent PCI. Copyright © 2016 Elsevier Inc. All rights reserved.

    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

    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

    BACKGROUND: Early stent thrombosis (ST) within 30 days after primary percutaneous coronary intervention in ST-segment-elevation myocardial infarction is a serious event. We sought to determine the predictors of and risk of mortality after early ST according to procedural antithrombotic therapy...... with bivalirudin compared with heparin±GPI because of increased ST within 4 hours after primary percutaneous coronary intervention. However, the mortality attributable to early ST was significantly lower after bivalirudin than after heparin±GPI. CLINICAL TRIAL REGISTRATION: URL: http....... METHODS AND RESULTS: In a patient-level pooled analysis from the Harmonizing Outcomes With Revascularization and Stents in Acute Myocardial Infarction (HORIZONS-AMI) and European Ambulance Acute Coronary Syndrome Angiography (EUROMAX) trials, we examined 30-day outcomes in 4935 patients undergoing primary...

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

    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.

    Bradycardia on presentation is frequently observed in patients with right coronary artery ST-segment elevation myocardial infarction, but it is largely unknown whether it predicts poor angiographic or clinical outcomes in that patient population. We sought to determine the prognostic implications of admission heart rate (AHR) in patients with ST-segment elevation myocardial infarction and a right coronary artery culprit lesion. We analyzed 1460 patients with ST-segment elevation myocardial infarction and a right coronary artery culprit lesion enrolled in the randomized HORIZONS-AMI (Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction) trial who underwent primary percutaneous coronary intervention. Patients presenting with high-grade atrioventricular block were excluded. Outcomes were examined according to AHR range (AHR 100 beats per minute). Angiographic analysis showed no significant association between AHR and lesion location or complexity. On multivariate analysis, admission bradycardia (AHR ST-segment elevation myocardial infarction and a right coronary artery culprit lesion undergoing primary percutaneous coronary intervention, admission bradycardia was not associated with increased mortality or major adverse cardiac events at 1 year.

    High platelet reactivity (HPR) was studied in patients presenting with ST-segment elevation myocardial infarction (STEMI) due to stent thrombosis (ST) undergoing immediate percutaneous coronary intervention (PCI). HPR on P2Y 12 inhibitors (HPR-ADP) is frequently observed in stable patients who have experienced ST. The HPR rates in patients presenting with ST for immediate PCI are unknown. Consecutive patients presenting with definite ST were included in a multicenter ST registry. Platelet reactivity was measured before immediate PCI with the VerifyNow P2Y 12 or Aspirin assay. Platelet reactivity was measured in 129 ST patients presenting with STEMI undergoing immediate PCI. HPR-ADP was observed in 76% of the patients, and HPR on aspirin (HPR-AA) was observed in 13% of the patients. HPR rates were similar in patients who were on maintenance P2Y 12 inhibitor or aspirin since stent placement versus those without these medications. In addition, HPR-ADP was similar in patients loaded with a P2Y 12 inhibitor shortly before immediate PCI versus those who were not. In contrast, HPR-AA trended to be lower in patients loaded with aspirin as compared with those not loaded. Approximately 3 out of 4 ST patients with STEMI undergoing immediate PCI had HPR-ADP, and 13% had HPR-AA. Whether patients were on maintenance antiplatelet therapy while developing ST or loaded with P2Y 12 inhibitors shortly before undergoing immediate PCI had no influence on the HPR rates. This raises concerns that the majority of patients with ST have suboptimal platelet inhibition undergoing immediate PCI. Copyright © 2017 American College of Cardiology Foundation.

    Wolff-Parkinson-White (WPW) syndrome is an uncommon cardiac condition where there is an abnormal band of atrial tissue connecting atria and ventricles which can electrically bypass atrioventricular node. The anaesthetic management in these patients is challenging as life threatening complications can occur perioperatively like paroxysmal supraventricular tachycardia and atrial fibrillation. Also, regional anaesthetic technique like subarachnoid block is a safe and cost effective alternative to general anaesthesia as it avoids polypharmacy. We report the successful anaesthetic management of Wolff Parkinson White syndrome in a primi with hydatiform mole posted for suction and evacuation.

    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.

    The purpose of the present study was to determine the prognostic value of N-terminal pro-brain natriuretic peptide (NT-pro-BNP), among other serum biomarkers, on cardiac magnetic resonance (CMR) imaging parameters of cardiac function and infarct size in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention. We measured NT-pro-BNP, cardiac troponin T, creatinine kinase-MB fraction, high-sensitivity C-reactive protein, and creatinine on the patients' arrival at the catheterization laboratory in 206 patients with ST-segment elevation myocardial infarction. The NT-pro-BNP levels were divided into quartiles and correlated with left ventricular function and infarct size measured by CMR imaging at 4 to 6 months. Compared to the lower quartiles, patients with nonanterior wall myocardial infarction in the highest quartile of NT-pro-BNP (> or = 260 pg/ml) more often had a greater left ventricular end-systolic volume (68 vs 39 ml/m(2), p pro-BNP level of > or = 260 pg/ml was the strongest independent predictor of left ventricular ejection fraction in patients with nonanterior wall myocardial infarction compared to the other serum biomarkers (beta = -5.8; p = 0.019). In conclusion, in patients with nonanterior wall myocardial infarction undergoing primary percutaneous coronary intervention, an admission NT-pro-BNP level of > or = 260 pg/ml was a strong, independent predictor of left ventricular function assessed by CMR imaging at follow-up. Our findings suggest that NT-pro-BNP, a widely available biomarker, might be helpful in the early risk stratification of patients with nonanterior wall myocardial infarction.

    Asymptomatic acute ischemic stroke (aAIS) following primary percutaneous coronary intervention (p-PCI) in patients with acute coronary syndrome (ACS) has not been studied in detail. Of 75 patients who underwent p-PCI, 26 (34.7%) developed aAIS as determined by diffusion-weighted magnetic resonance imaging (MRI). Including the approach to the coronary artery (via lower limb or right upper limb), 23 factors were compared between patients with (n=26) and without (n=49) aAIS. Age, hypertension, smoking, plasma glucose levels, Killip grade, right coronary artery (RCA) as culprit vessel, percutaneous coronary intervention (PCI) time, and the frequency of device insertion into the coronary artery differed in a statistically significant manner. However, multivariate analysis showed that the RCA (odds ratio 3.477) and the frequency of device insertion (1.375) were independent factors linked to the incidence of aAIS. Moreover, anterior or posterior location and left or right cerebral circulation of aAIS were equivalent in both approaches. Cranial MRI images following emergency PCI revealed that 34.7% of the patients with ACS had aAIS that might be caused by manipulating the catheter or devices in the ascending aorta, micro-air bubble embolism during injection, or micro-thrombus embolism derived from the ACS lesions during the PCI procedure.

    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.

    2012-11-01

    We describe our technique of percutaneous suprapubic catheter insertion with special reference to steps that help to avoid common complications of haematuria and catheter misplacement. The procedure is performed using a stainless steel reusable trocar under local infiltrative anaesthesia, usually at the bedside. After clinical confirmation of a full bladder, the trocar is advanced into the bladder through a skin incision. Once the bladder is entered, the obturator is removed and the assistant inserts a Foley catheter followed by rapid balloon inflation. Slight traction is applied to the catheter for about five minutes. Patients with previous lower abdominal surgery, an inadequately distended bladder or acute pelvic trauma do not undergo suprapubic catheterisation using this method. The procedure was performed in 72 men (mean age: 42.4 years, range: 18-78 years) with urinary retention with a palpable bladder. The average duration of the procedure was less than five minutes. No complications were noted in any of the patients. Trocar suprapubic catheter insertion is a safe and effective bedside procedure for emergency bladder drainage and can be performed by resident surgeons. The common complications associated with the procedure can be avoided with a few careful steps.

    This retrospective cohort study evaluated the cumulative live birth rate in women with polycystic ovary syndrome (PCOS) and isolated polycystic ovaries (PCO) undergoing in-vitro fertilisation (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. The main outcome measure was cumulative live birth in the fresh plus all the frozen embryo transfers combined after the same stimulation cycle. Women in both the PCOS (n = 104) and isolated PCO groups (n = 184) had higher ovarian response parameters compared to age-matched controls (n = 576), and higher rates of withholding fresh embryo transfer for risk of ovarian hyperstimulation syndrome (OHSS). The actual incidence of moderate to severe OHSS was significantly higher in the PCOS (11.5 %) but not the isolated PCO group (8.2%) compared to controls (4.9%). The live birth rates in the fresh cycle were comparable among the 3 groups, but the PCOS group had a significantly higher miscarriage rate compared to the other 2 groups. Cumulative live birth rate was significantly higher in the isolated PCO group (60.3%), but not the PCOS group (50.0%), compared to controls (47.5%). Women in the isolated PCO group, but not the PCOS group, had a significantly higher cumulative live birth rate compared to controls. This could be explained by the quantitative effect of the higher number of transferable embryos obtained per stimulation cycle, which is uncompromised by the unfavourable embryo competence otherwise observed in PCOS.

    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.

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

    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.

    Conflicting data have been reported on the effects of low-osmolar and iso-osmolar contrast media on contrast-induced acute kidney injury (CI-AKI). In particular, no clinical trial has yet focused on the effect of contemporary contrast media on CI-AKI, epicardial flow, and microcirculatory function in patients with ST-segment elevation acute myocardial infarction who undergo primary percutaneous coronary intervention. The Contrast Media and Nephrotoxicity Following Coronary Revascularization by Angioplasty for Acute Myocardial Infarction (CONTRAST-AMI) trial is a prospective, randomized, single-blind, parallel-group, noninferiority study aiming to evaluate the effects of the low-osmolar contrast medium iopromide compared to the iso-osmolar agent iodixanol on CI-AKI and tissue-level perfusion in patients with ST-segment elevation acute myocardial infarction. Four hundred seventy-five consecutive, unselected patients who underwent primary percutaneous coronary intervention were randomized to iopromide (n = 239) or iodixanol (n = 236). All patients received high-dose N-acetylcysteine and hydration. The primary end point was the proportion of patients with serum creatinine (sCr) increases ≥25% from baseline to 72 hours. Secondary end points were Thrombolysis In Myocardial Infarction (TIMI) myocardial perfusion grade, increase in sCr ≥50%, increase in sCr ≥0.5 or ≥1 mg/dl, and 1-month major adverse cardiac events. The primary end point occurred in 10% of the iopromide group and in 13% of the iodixanol group (95% confidence interval -9% to 3%, p for noninferiority = 0.0002). A TIMI myocardial perfusion grade of 0 or 1 was present in 14% of patients in the 2 groups. No differences between the 2 groups were found in any of the secondary analyses of sCr increase. No significant difference in 1-month major adverse cardiac events was found (8% vs 6%, p = 0.37). In conclusion, in a population of unselected patients with ST-segment elevation acute myocardial infarction

    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.

    The prevalence and impact of early ventricular arrhythmias (ventricular tachycardia [VT]/ventricular fibrillation [VF]) occurring before mechanical revascularization for acute ST segment elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention are poorly understood. We sought to investigate the association between early VT/VF and long-term clinical outcomes using data from the Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction trial. Among 3,602 patients with STEMI, 108 patients (3.0%) had early VT/VF. Baseline clinical characteristics were similar in patients with versus without early VT/VF. Patients with early VT/VF had shorter symptom-to-balloon times and lower left ventricular ejection fraction and underwent more frequent thrombectomy compared with patients without early VT/VF. Adjusted 3-year rates of all-cause death (15.7% vs 6.5%; adjusted hazard ratio 2.62, 95% confidence interval 1.48 to 4.61, p stent thrombosis (13.7% vs 5.7%; adjusted hazard ratio 2.74, 95% confidence interval 1.52 to 4.93, p Stents in Acute Myocardial Infarction trial, VT/VF occurring before coronary angiography and revascularization in patients with STEMI was strongly associated with increased 3-year rates of death and stent thrombosis.

    Full Text Available A 28-year-old female who underwent live donor liver transplantation 3 years prior presented after percutaneous liver biopsy with abdominal and shoulder pain, nausea, vomiting, and elevated liver enzymes. Computed tomography (CT showed an intrahepatic and subcapsular hematoma. There was a progressive increase in liver enzymes, bilirubin, and INR and a decline in hemoglobin. Subsequent CT imaging revealed flattening of the portal vein consistent with compression by the enlarging hematoma. Liver failure ensued and the patient required urgent retransplantation. The explant demonstrated ischemic necrosis of greater than 90% of the liver parenchyma. We report this case of “Hepatic Compartment Syndrome” leading to fulminant hepatic failure.

    Full Text Available 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.

    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

    Aim: Supine hypotensive syndrome (SHS) can occur in women in the second half of pregnancy due to compression of the aorta and inferior vena cava by the gravid uterus. This results in a decrease in cardiac output with effects ranging from transient asymptomatic hypotension to cardiovascular collapse. SHS can be easily avoided by left lateral tilt positioning. We undertook a nationwide survey to assess the awareness amongst senior computed tomography (CT) radiographers of the potential risk of SHS in women in this patient group, and to identify the extent to which preventative practices and protocols are in place. Methods and materials: A questionnaire was sent to superintendent CT radiographers at all acute NHS Trusts in England and Wales examining awareness of the risk of SHS and the preventative practices and protocols currently used. Results: Completed questionnaires were received from 64% institutions. Of respondents who scan women in this patient group, only 44% were aware of the risk of SHS. No institution had a written protocol specifying positioning of women in this patient group. Seventy-five percent of institutions never employed oblique positioning. Eighty-five percent felt that specific guidelines from the Society of Radiographers or Royal College of Radiologists would be helpful. Conclusion: Current awareness and practices for preventing this easily avoidable but potentially harmful condition are inadequate. Central guidance would be welcomed by a large majority of respondents.

    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.

    Patients with Williams syndrome (WS) undergoing cardiac surgery are at risk for major adverse cardiac events (MACE). Prevalence and risk factors for such events have not been well described. We sought to define frequency and risk of MACE in patients with WS using a multicenter clinical registry. We identified cardiac operations performed in patients with WS using the Society of Thoracic Surgeons Congenital Heart Surgery Database (2000-2012). Operations were divided into 4 groups: isolated supravalvular aortic stenosis, complex left ventricular outflow tract (LVOT), isolated right ventricular outflow tract (RVOT), and combined LVOT/RVOT procedures. The proportion of patients with MACE (in-hospital mortality, cardiac arrest, or postoperative mechanical circulatory support) was described and the association with preoperative factors was examined. Of 447 index operations (87 centers), median (interquartile range) age and weight at surgery were 2.4 years (0.6-7.4 years) and 10.6 kg (6.5-21.5 kg), respectively. Mortality occurred in 20 patients (5%). MACE occurred in 41 patients (9%), most commonly after combined LVOT/RVOT (18 out of 87; 21%) and complex LVOT (12 out of 131; 9%) procedures, but not after isolated RVOT procedures. Odds of MACE decreased with age (odds ratio [OR], 0.99; 95% confidence interval [CI], 0.98-0.99), weight (OR, 0.97; 95% CI, 0.93-0.99), but increased in the presence of any preoperative risk factor (OR, 2.08; 95% CI, 1.06-4.00), and in procedures involving coronary artery repair (OR, 5.37; 95% CI, 2.05-14.06). In this multicenter analysis, MACE occurred in 9% of patients with WS undergoing cardiac surgery. Demographic and operative characteristics were associated with risk. Further study is needed to elucidate mechanisms of MACE in this high-risk population. Copyright © 2015 The American Association for Thoracic Surgery. Published by Elsevier Inc. All rights reserved.

    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

    Importance Low cardiac output syndrome after cardiac surgery is associated with high morbidity and mortality in patients with impaired left ventricular function. Objective To assess the ability of preoperative levosimendan to prevent postoperative low cardiac output syndrome. Design, Setting, and Participants 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). Interventions 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. Main Outcomes and Measures 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. Results 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.

    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.

    Full Text Available Aims. 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.

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

    The 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

    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.

    Conclusions: Percutaneous image-guided RFA is an option in patients where most other tumor management modalities have been exhausted or rejected. RFA may not be free from side effects such as postablation syndrome, pain, and there may be other serious complications such as bleeding, but based on our observations, percutaneous image-guided RFA of tumors is a safe palliative and therapeutic treatment option.

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

    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)

    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 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.

    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.

    The aim of this study was to evaluate the prognostic value of soluble CD40 ligand (sCD40L) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing a primary percutaneous coronary intervention (PCI). The prognostic value of sCD40L has been documented in patients with acute coronary syndrome; however, its value in acute STEMI remains unclear. We prospectively enrolled 499 consecutive STEMI patients (397 men, 102 women) undergoing primary PCI. The study population was divided into tertiles on the basis of admission sCD40L values. The high sCD40L group (n=168) included patients with a value in the third tertile (≥0.947 mg/l) and the low sCD40L group (n=331) included patients with a value in the lower two tertiles (0.947 mg/l) is a powerful independent predictor of 1-year all-cause mortality (odds ratio: 3.68; 95% confidence interval: 1.54-8.77; P=0.003). The results of this study suggest that a high sCD40L level at admission is associated with increased in-hospital and 1-year all-cause mortality rates in patients with STEMI undergoing primary PCI.

    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

    Acute kidney injury (AKI) is a common complication after coronary angiography. Early biomarkers of this disease are needed since increase in serum creatinine levels is a late marker. To assess the usefulness of urinary kidney injury molecule-1 (uKIM-1), neutrophil gelatinase-associated lipocalin (uNGAL) and liver-type fatty acid-binding protein (uL-FABP) for early detection of AKI in these patients, comparing their performance with another group of cardiac surgery patients. Biomarkers were measured in 193 patients, 12 h after intervention. In the ROC analysis, AUC for KIM-1, NGAL and L-FABP was 0.713, 0.958 and 0.642, respectively, in the coronary angiography group, and 0.716, 0.916 and 0.743 in the cardiac surgery group. Urinary KIM-1 12 h after intervention is predictive of AKI in adult patients undergoing coronary angiography, but NGAL shows higher sensitivity and specificity. L-FABP provides inferior discrimination for AKI than KIM-1 or NGAL in contrast to its performance after cardiac surgery. This is the first study showing the predictive capacity of KIM-1 for AKI after coronary angiography. Further studies are still needed to answer relevant questions about the clinical utility of biomarkers for AKI in different clinical settings.

    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

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

    Full Text Available 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.

    Sugammadex is a cylodextrin derivate that encapsulates steroidal neuromuscular blocker agents and is reported as a safe and well-tolerated drug. In this case report, we present a patient who developed grade 3 anaphylaxis just after sugammadex administration. A 22-year-old woman with diagnosis of Weaver syndrome was scheduled for bilateral mammoplasty and resection of unilateral accessory breast tissue resection. Anesthesia was induced and maintained by propofol, rocuronium, and remifentanil. At the end of the operation, sugammadex was administered and resulted in initially hypotension and bradycardia then the situation worsened by premature ventricular contraction and bigeminy with tachycardia, bronchospasm, and hypoxia. The Ring and Messmer clinical severity scale grade 3 anaphylactic reaction occurred just after sugammadex injection and the patient developed prolonged hypotension with recurrent cardiac arrhythmias in postoperative 12 hours. Treatment was initiated bolus injections of ephedrine, epinephrine, lidocaine, steroids and antihistaminic and continued with lidocaine bolus dosages and norepinephrine infusion for the postoperative period. The general condition of the patient improved to normal 3 hours after the sugammadex injection, and she was moved to the intensive care unit. At 2nd and 8th hours of intensive care unit follow-up, she developed premature ventricular contraction and bigeminy with the heart rate of 130 to 135 beats/min, which returned to sinus rhythm with 50 mg lidocaine. After that, no symptoms were observed and the patient was discharged to plastic surgery clinic at the following day. Sugammadex may result in life-treating anaphylactic reaction even in a patient who did not previously expose to drug. Moreover, prolonged cardiovascular collapse and cardiac arrhythmias may occur.

  10. SERUM ELECTROLYTES AND OUTCOME IN PATIENTS UNDERGOING ENDOSCOPIC GASTROSTOMY

    Directory of Open Access Journals (Sweden)

    Joana VIEIRA

    Full Text Available ABSTRACT BACKGROUND: Percutaneous endoscopic gastrostomy (PEG is a gold standard for long term enteral feeding. Neurologic dysphagia and head/neck cancer are the most common indications for PEG as they can lead to protein-energy malnutrition and serum electrolyte abnormalities, with potential negative impact on metabolic balance. Refeeding syndrome may also be related with severe electrolyte changes in PEG-fed patients and contribute to poor prognosis. OBJECTIVE: This study aims to evaluate the changes in serum concentrations of the main electrolytes and its possible association with the outcome. METHODS: Retrospective study of patients followed in our Artificial Nutrition Clinic, submitted to PEG from 2010 to 2016, having head/neck cancer or neurologic dysphagia, who died under PEG feeding. Serum electrolytes (sodium, potassium, chlorine, magnesium, calcium and phosphorus were evaluated immediately before the gastrostomy procedure. Survival after PEG until death was recorded in months. RESULTS: We evaluated 101 patients, 59 with electrolyte alterations at the moment of the gastrostomy. Sodium was altered in 32 (31.7%, magnesium in 21 (20.8%, chlorine in 21 (20.8%, potassium in 14 (13.8%, calcium in 11 (10.9 % and phosphorus in 11 (10.9%. The survival of patients with low sodium (<135 mmol/L was significantly lower when compared to patients with normal/high values, 2.76 months vs 7.80 months, respectively (P=0.007. CONCLUSION: Changes in serum electrolytes of patients undergoing PEG were very common. More than half showed at least one abnormality, at the time of the procedure. The most frequent was hyponatremia, which was associated with significantly shorter survival, probably reflecting severe systemic metabolic distress.

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

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

    To identify and map the course of the peripheral branches of the cranial nerve preoperatively and percutaneously. Prospective study. Preoperative percutaneous nerve mapping performed prior to the operation under deep sedation or general anesthesia without muscle paralysis. Private office surgery suite, freestanding surgery center, and regional medical centers. A total of 142 patients undergoing head and neck surgery and facial plastic surgery between August 1994 and July 1999. Monopolar probe was used for nerve stimulation. Electromyographic reading was done through intramuscular bipolar recording electrodes. The equipment used was a nerve monitor. The mandibular divisions were tested in 142 cases, the frontal division in 60 cases, the accessory nerve in 12 cases, and the hypoglossal nerve in 3 cases. Satisfactory mappings were obtained in 115 cases of the mandibular division, 49 cases of the frontal division, 8 cases of the accessory division, and 1 case of the hypoglossal nerve. Preoperative percutaneous nerve mapping is a new method of identifying the location of the peripheral branches of the cranial nerves. Identifying and mapping the course of peripheral branches of the cranial nerves safely assists the head and neck surgeon in the placement of incisions in a favorable location and in the dissection of the area involving the nerves. Mapping alerts the surgeon to an area containing a nerve and allows the surgeon to avoid just the specific area where a nerve is present, preventing large-scale abandonment of unmapped areas for fear of potential nerve damage.

    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.

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

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

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

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

    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.

    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

    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.

    Rapid prototyping is a technique used for creating computer images in three dimensions more efficiently than classic techniques. Percutaneous nephrolithotomy (PCNL) is a popular method to remove kidney stones; however, broader use by the urologic community has been hampered by the morbidity associated with needle puncture to gain access to the renal calix (bleeding, pneumothorax, hydrothorax, inadvertent colon injury). A training model to improve technique and understanding of renal anatomy could improve complications related to renal puncture; however, no model currently exists for resident training. We created a training model using the rapid prototyping technique based on abdominal CT images of a patient scheduled to undergo PCNL. This allowed our staff and residents to train on the model before performing the operation. This model allowed anticipation of particular difficulties inherent to the patient's anatomy. After training, the procedure proceeded without complication, and the patient was discharged at postoperative day 1 without problems. We hypothesize that rapid prototyping could be useful for resident education, allowing the creation of numerous models for research and surgical training. In addition, we anticipate that experienced urologists could find this technique helpful in preparation for difficult PCNL operations.

    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

    We evaluated the effectiveness and clinical usefulness of percutaneous renal biopsy by using automated biopsy gun under the real-time ultrasonographic guidance that was performed in 17 patients with diffuse renal disease. We retrospectively analysed the histopathological diagnosis and the patients' status after percutaneous renal biopsy.Adequate amount of tissue for the histologic diagnosis could be obtained in al patients. Histopathologic diagnosis included the minimal change nephrotic syndrome in 6 patients, the membrano proliferative glomerulonephritis in 4,the membranous glomerulonephritis in 2, the glomerulosclerosis in 2, Ig A nephropathy in 2, and the normal finding in 1. Significant complication occurred in only one patient who developed a transient loss of sensation at and around the biopsy site. In conclusion, automated biopsy gun was a very useful device in performing percutaneous biopsy for diffuse renal disease with a high success rate and a low complication rate

    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.

  16. Percutaneous tracheostomy: a comprehensive review

    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

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

    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.

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

    Immediate reopening of acutely occluded coronary arteries via primary percutaneous coronary intervention (PCI) is the treatment of choice to salvage the ischemic myocardium in the setting of ST-segment elevation myocardial infarction (STEMI). However, the sudden re-initiation of blood flow achieved with PCI can lead to a local acute inflammatory response with further endothelial and myocardial damage. This phenomenon, described as 'reperfusion injury', has been recognized for several decades, yet no pharmacologic intervention has so far succeeded in reducing myocardial damage linked to reperfusion. FX06 is a naturally occurring peptide derived from the neo-N-terminus of fibrin (Bbeta(15-42)). It prevents leukocyte migration through the gap junctions of endothelial cells. Experimental studies have shown that FX06 inhibits the binding of the proinflammatory fibrin E1 fragment to VE-cadherin expressed in the adherence junction. It represents a novel approach to reducing local and systemic inflammation, including myocardial reperfusion injury, in the adherens junction. The present multicenter, double-blind, randomized, placebo-controlled study is designed to test the hypothesis that FX06 injection during and immediately after primary PCI can reduce infarct size in patients with STEMI. The primary outcome measure of efficacy in this study is the degree of myocardial salvage calculated as the difference between the perfusion defect before and after PCI, determined by myocardial perfusion scintigraphy during rest. Further, infarct size at the end of the index hospitalization, as well as at 4 months, will be measured by cardiac magnetic resonance imaging. The present position paper describes the rationale, design and the methods utilized in this trial. 2007 S. Karger AG, Basel

    To gain insight into the ovarian stromal blood flow in women with polycystic ovary syndrome (PCOS) as compared with women with normal ovulation, good ovarian reserve, and infertility and to evaluate the role of stromal flow in these patients to predict clinical pregnancy in an assisted reproductive technologies setting. A prospective observational cohort study. A university-affiliated reproductive medicine unit. Eighteen consecutive patients with PCOS (study) compared with 101 patients with normal ovulation and infertility (control), undergoing their first IVF-ET treatment at our unit. Women with low ovarian reserve were excluded a priori from evaluation. Basal ovarian reserve parameters and stromal flow studies were conducted as routinely performed in our unit, in a natural cycle before starting treatment. None. Basal ovarian endocrine, sonographic, and stromal flow studies were compared between the groups. After completion of treatment, the stromal flow studies were compared between conception and nonconception cycles. Patients' characteristics and basal ovarian reserve, including endocrine and sonographic parameters, were similar between the PCOS and control groups. Only antral follicle count and LH/FSH ratio were higher in the PCOS as compared with the control group, corresponding to 15.11 ± 6.05 versus 9.05 ± 4.77 and 1.14 ± 0.64 versus 0.79 ± 0.37, respectively. Basal stromal flow indices were similar between the PCOS group and the group with normal ovulation and good ovarian reserve. Clinical pregnancy rate per initiated cycle was 50.0% and 39.6% in the PCOS and control groups, respectively, with no significant difference. Flow indices were similar between conception cycles in the PCOS and control groups. As well, the indices did not differ significantly between conception and nonconception cycles within the PCOS and control groups. Basal ovarian stromal blood flow does not differ between women with PCOS and women with normal ovulation, good ovarian

    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

  6. Percutaneous biliary drainage and stenting

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

    The 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)

    The prognostic value of cystatin C (CysC) has been documented in patients with acute coronary syndrome without ST-segment elevation. However, its value in acute ST-segment elevation myocardial infarction (STEMI) remains unclear. The aim of this study was to evaluate the prognostic value of CysC in patients with STEMI undergoing primary percutaneous coronary intervention (PCI). We prospectively enrolled 475 consecutive STEMI patients (mean age 55.6±12.4 years, 380 male, 95 female) undergoing primary PCI. The study population was divided into tertiles based on admission CysC values. The high CysC group (n=159) was defined as a value in the third tertile (>1.12 mg/L), and the low CysC group (n=316) included those patients with a value in the lower two tertiles (≤1.12 mg/L). Clinical characteristics and in-hospital and one-month outcomes of primary PCI were analyzed. The patients of the high CysC group were older (mean age 62.8±13.1 vs. 52.3±10.5, P1.12 mg/L) was found to be a powerful independent predictor of one-month cardiovascular mortality (odds ratio, 5.3; 95% confidence interval, 1.25-22.38; P=.02). These results suggest that a high admission CysC level was associated with increased in-hospital and one-month cardiovascular mortality in patients with STEMI undergoing primary PCI.

    The aim of this study was to evaluate the prognostic value of D-dimer in patients with STEMI undergoing primary percutaneous coronary intervention (PCI). The prognostic value of D-dimer has been documented in patients with acute coronary syndrome without ST-segment elevation. However, its value in acute ST-segment elevation myocardial infarction (STEMI) remains unclear. We prospectively enrolled 453 consecutive STEMI patients (mean age 55.6 ± 12.4 years, 364 male, 89 female) undergoing primary PCI. The study population was divided into tertiles based on admission D-dimer values. The high D-dimer group (n = 151) was defined as a value in the third tertile [>0.72 ug/ml fibrinogen equivalent units (FEU)], and the low D-dimer group (n = 302) included those patients with a value in the lower two tertiles (≤0.72 ug/ml FEU). Clinical characteristics, in-hospital and 6-month outcomes of primary PCI were analyzed. The patients of the high D-dimer group were older (mean age 60.1 ± 13.5 versus 52.4 ± 10.6, P 0.72 ug/ml FEU) was found to be a powerful independent predictor of 6-month all-cause mortality (odds ratio: 10.1, 95% confidence interval: 1.24-42.73, P = 0.03). These results suggest that a high admission D-dimer, level was associated with increased in-hospital cardiovascular mortality and 6-month all-cause mortality in patients with STEMI undergoing primary PCI.

    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.

    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

    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

    Antegrade placement of ureteral stents has successfully achieved in 41 of 46 ureters. When it was difficult to advance ureteral stents through the lesion, it was facilitated by retrograde guide-wire snare technique through urethra. Complications associated with the procedure were non-function of ureteral stent by occlusion, upward migration,and spontaneous fracture of ureteral stent. These complications were managed by percutaneous nephrostomy and removal of ureteral stents by guide-wire snare technique and insertion of a new ureteral stent. While blood cell in urine was markedly increased in about 50% of patients following the procedure.

    A case is reported of a cystic craniopharyngioma involving the floor and walls of the third ventricle. Pronounced anterograde and retrograde amnesia were documented preoperatively by formal testing. Rapid improvement in both new learning capacity and remote memory occurred after percutaneous twist drill drainage of the cystic portion of the tumour. The relevance of these observations to the amnesic syndrome and its neuropathological basis is discussed. Images PMID:1011035

    Patients with diabetes mellitus have reduced longevity after acute coronary syndromes and revascularization. However, knowledge of the long-term complication rates and patterns from an everyday life setting is lacking. Consecutive patients undergoing percutaneous coronary intervention included in the Swedish Coronary Angiography Angioplasty Registry (SCAAR) between 2006 and 2010 and with no previous revascularization were prospectively followed up for combined cardiovascular events (first of all-cause mortality, myocardial infarction, stroke, and heart failure) until December 31, 2010. The mean follow-up period was 920 days (SD, 530 days). Differences in background and procedural characteristics were adjusted for in a multivariate Cox regression model. Of 58 891 patients, mean age 67 years, 19% had diabetes mellitus; 27% of them were on diet treatment, 33% on oral glucose lowering, and 40% on insulin treatment. At admission, cardiovascular risk factors, multiple coronary vessel, and left main stem disease were more frequent in patients with diabetes mellitus and their revascularization was less often complete. The adjusted risk for combined cardiovascular events was higher in patients on insulin (hazard ratio [95% confidence interval], 1.63 [1.55-1.72]), on oral treatment (1.23 [1.15-1.31]), and on diet alone (1.21 [1.12-1.29]) compared with patients without diabetes mellitus. Insulin-treated patients ran an increased risk of restenosis (1.54 [1.39-1.71]) and stent thrombosis (1.56 [1.25-1.96]). The prognosis after a first percutaneous coronary intervention is more severe in patients with diabetes mellitus, in particular, in patients treated with insulin, with higher rates of mortality, cardiovascular events, and stent thrombosis over the following 5 years. © 2015 American Heart Association, Inc.

    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.

    In The Netherlands, more than 30.000 patients undergo a percutaneous coronary intervention every year, during which a coronary stent implantation will be performed in 90% of the cases. It is estimated that more than 5 million coronary stent implantations will be performed worldwide this year. While these numbers are impressive, however, coronary stents still have as a limitation the possibility of stent thrombosis. This has been and is an important stimulus for the development of both coronary stents, from a bare metal stent via a drug eluting stent to the present-day development of bio-absorbable stents, and anti-platelet drugs,from acenocoumarol to thieropyridines. The possibility of shortening the period of use of this powerful medication by developing new kinds of non-thrombogenic stents would, for example, make it possible to achieve significant reductions in subsequent bleeding during (dental) procedures.

    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.

    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.

    Chiao-Hsiung Chuang

    2008-11-01

    Full Text Available The rendezvous technique, combining percutaneous and endoscopic procedures, is a safe and effective method to achieve biliary cannulation if an endoscopic approach fails. The two procedures in this technique can be carried out simultaneously or in stages. A simultaneous approach is reported to be associated with fewer complications, and patients undergoing this approach can recover and be discharged more rapidly. Here, we report a complication of pneumoperitoneum in a patient who underwent percutaneous and endoscopic procedures simultaneously for the removal of a common bile duct stone. It was supposed that prolonged air insufflation during endoscopy forced intestinal air to track into the peritoneal cavity through the bile ducts and the puncture tract. Accordingly, a short wait before removing the percutaneous catheter to deflate the intestinal air will be helpful to avoid such a complication.

    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.

    Since its introduction in late 1970's, percutaneous nephrolithotomy (PNL) has undergone an evolution in both equipment and technique. This evolution still continues today in the era of minimally invasive treatment options, and is evidenced by the numerous publications. PNL is generally advantageous...... in the management of large renal stones (>1.5-2 cm) with high stone-free rates and considerable complication rates. However this technique is especially competing with retrograde intrarenal surgery and laparoscopic techniques. Therefore the CROES Global PNL Study Group prospectively collected data of over 5800...... patients managed with PNL worldwide and analyzed the data in detail, producing more than 25 scientific papers.

    2012-10-23

    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.

    Percutaneous transluminal angioplasty (PTA) is a non-operative therapeutic procedure to the dilation of stenosis or to the recanalization of occlusion in atherosclerotic arteries using of dilatation catheters. PTA was performed 37 times in 34 patients with arteriosclerotic for 1 year and 4 months from March, 1982 to June, 1983 at department of radiology, Klinikum Barmen/west Germany. The results were as follows; 1. The male to female ratio was 2 : 1 and peak age range was from 61 to 70. 2. The most common indication was clinical stage II b with 19 cases (51.3%). 3. PTA was performed most commonly in superficial femora artery in 25 cases (67.5%). 4. Acute major complication occurred in 2 cases (5.4%). PTA is a alternative or complementary therapeutic procedure to vascular surgery.

    1992-09-01

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

    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.

    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.

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

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

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

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

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

  7. Systemic inflammatory response syndromes in the era of interventional cardiology.

    Science.gov (United States)

    2018-04-12

    Systemic inflammatory response syndrome (SIRS), initially reported after cardiovascular surgery, has been described after various interventional cardiology procedures, including endovascular/thoracic aortic repair (EVAR/TEVAR), implantation of heart rhythm devices, percutaneous coronary intervention (PCI), electrophysiology procedures (EP), and transcatheter aortic valve implantation (TAVI). In these settings, a comprehensive understanding of the triggers, pathogenesis as well as a common diagnostic/therapeutic algorithm is lacking and will be discussed in this review. SIRS occurs in about 40% and 50% of patients undergoing TEVAR/EVAR and TAVI respectively; it affects 0.1% of patients undergoing implantation of heart rhythm devices. Prevalence is unknown after PCI or EP. Clinical presentation includes fever, dyspnoea/tachypnoea, tachycardia, weakness, chest pain and pericardial/pleural effusion. Several triggers can be identified, related to implanted devices, biomaterial, and procedural aspects (prolonged hypotension, aneurysm thrombus manipulation, active fixation atrial leads, coronary microembolization, balloon dilatation/stent implantantation, contrast medium, coronary/myocardial microperforation). Nonetheless, these triggers share three main pathogenic pathways leading to SIRS clinical manifestations: leucocytes activation, endothelial injury/activation, and myocardial/pericardial injury. Therapy consists of non-steroidal agents, with corticosteroids as second-line treatment in non-responders. Although a benign evolution is reported after implantation of heart rhythm devices, PCI and EP, major adverse events may occur after EVAR/TEVAR and TAVI at short- and mid-term follow up.

    2015-04-01

    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.

    Full Text Available A 56-year-old woman with no medical history presented to the emergency department complaining of oppressive chest pain of three hours of duration triggered by walking. An electrocardiogram (ECG performed at hospital admission showed ST-segment depression and T-wave inversion in left precordial and inferior leads. Serum troponin I levels were above the normal values. Non ST-segment elevation acute coronary syndrome (NSTEACS was diagnosed and an invasive approach with a percutaneous coronary intervention was performed. No obstructive coronary lesions were observed. However a tortuous coronary fistula emerging from the left-anterior descending coronary artery to the pulmonary artery was observed. Coronary arterio-venous fistulas are present in 0.002% of the general population and in 0.25% of patients undergoing cardiac catheterization for any cause. Most of them are asymptomatic. Ischemic symptoms may develop but are infrequent in patients with no atherosclerotic disease.

    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.)

  15. Percutaneous distraction lengthening in brachymetacarpia.

    Science.gov (United States)

    Volpi, Alexander D; Fragomen, Austin T

    2011-08-08

    Brachymetacarpia is a condition manifesting a shortened metacarpal that is caused by early closure of the epiphyseal plate and believed to arise idiopathically. The correction for brachymetacarpia is usually for cosmetic reasons as brachymetacarpia does not impair function. The literature indicates several different approaches to lengthening digits, including single-stage lengthening and rapid distraction lengthening with a bone graft. However, gradual distraction is the preferred method due to excellent cosmetic outcomes and few postoperative complications. This article reports a case of brachymetacarpia treated with distraction lengthening using a minimally invasive, percutaneous approach. A 16-year-old girl presented with a shortened left ring finger and underwent surgery to correct the deformity. The left ring finger measured 12 mm shorter than her right ring finger; however, there was normal mobility at the joints. In the operating room, an external fixator was attached using 4 self-drilling, self-tapping pins through several 3-mm skin incisions. The total fixation time was 14 weeks; however, the achieved length of 12 mm was achieved 6 weeks postoperatively. The healing index of the fixation period was 81 days/cm. The postoperative course and fixation period were uneventful, with no complications except for 2 pin infections that were treated with oral antibiotics. The method of gradual distraction lengthening in this case successfully achieved the desired length and yielded an excellent cosmetic result. Copyright 2011, SLACK Incorporated.

    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

  18. Percutaneous management of staghorn renal calculi

    International Nuclear Information System (INIS)

    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 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.

    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.

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

  4. Balloon Occlusion Types in the Treatment of Coronary Perforation during Percutaneous Coronary Intervention

    Directory of Open Access Journals (Sweden)

    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.

    2008-01-01

    Clopidogrel has become standard treatment after urgent percutaneous coronary revascularization. Due to its enhanced and irreversible platelet inhibition, patients undergoing urgent surgical revascularization have a higher risk of bleeding complications and transfusions. Therefore, the effect of preoperative continuous administration of clopidogrel on the incidence of hemorrhagic complications in patients undergoing off-pump coronary artery bypass surgery with acute coronary syndrome was evaluated. From March 2004 to September 2006, 172 patients with acute coronary syndrome underwent isolated off-pump coronary artery bypass surgery; 70 (40.7%) and 102 (59.3%) of these patients did or did not take clopidogrel before surgery respectively. Seventy patients in each group were matched using propensity scores and associations between preoperative continuous administration of clopidogrel and postoperative bleeding, hemostatic reoperation, blood products received, the need for multiple transfusions and early graft patency by coronary computed tomography were assessed. Univariate analysis showed the continuous clopidogrel group had similar levels of postoperative bleeding for 24 h (601.4±312.6 ml vs 637.2±452.4 ml, p=0.616) and rates of reexploration (1.4% vs 1.4%), perioperative blood transfusion (33.3% vs 34.3%, p>0.05) and platelet transfusion (2.9% vs 7.1%, p=0.44) compared with the non-continuous group. Preoperative continuous administration of clopidogrel did not increase the risk of hemorrhagic complications in patients with acute coronary syndrome undergoing isolated off-pump coronary artery bypass surgery. These findings indicate that surgery after clopidogrel treatment in patients with acute coronary syndrome should not be delayed until platelet function returns to normal because they may have a higher risk of recurrent myocardial ischemic events.

    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 The incidence of splenic abscesses is currently 0.14–0.7% with a reported mortality of 0–47%. The diagnosis of splenic abscess which has ruptured into the abdomen is often overlooked because of its rarity and its misleading clinical presentations. Percutaneous coronary interventions (PCIs and coronary stenting procedures increased from 184,000 to 885,000 (from 335 to 1,550 and from 3,000 to 770,000 (from 5 to 1,350 per one million inhabitants, respectively. A 40-year-old Asian male presented to our emergency department with upper abdominal pain 5 days after a percutaneous transluminal coronary angioplasty. Clinical examination raised the possibilities of acute pancreatitis and intraabdominal sepsis. An initial ultrasound of the abdomen and blood tests were negative. A computed tomography scan of the abdomen revealed a splenic abscess that had ruptured into the abdomen. Pus culture revealed a multidrug-resistant strain of Klebsiella pneumoniae that was sensitive to meropenem. The patient recovered quickly after open surgical drainage and antibiotic therapy. As this is the second case of splenic abscess and the first case report of a ruptured splenic abscess following a PCI, it will be rational to administer a short course of antibiotic prophylaxis for high-risk immunocompromised patients who are undergoing percutaneous transluminal coronary intervention.

    To analyse the effectiveness of percutaneous treatment of central venous obstruction in patients undergoing hemodialysis. In 100 patients, 107 central venous strictures (56 subclavian (occlusion:21, stenosis:35) and 51 innominate (occlusion:23,stenosis:28)) were assessed, and 170 percutaneous angioplasty procedures were performed. Balloon dilation of the venous lumen was the preferred mode, but if dilation was incomplete we inserted a stent at the site of the stricture. Technical success, procedural complications and the long-term patency rate were evaluated, and the patency difference according to location and degree of stricture, the existence of DM, and any history of central catheter insertion was also determined. We inserted 52 stents in 170 procedures, in 157 (92.4%) of which initial technical success was achieved. Stent migration occurred in two cases and balloon rupture in three. The 6- and 12-month primary patency rates were 46.2% and 24.1%, respectively, and the mean patency rate was 8.5 months. The 1-, 2-and 3-year accumulative patency rates were 59.8%, 47.5% and 35.7%, respectively, and the mean patency rate was 23.5 months. Other than in the history of central catheter insertion, there were no statistically significant differences in patency rates (p=0.0128). In hemodialysis patients with a central venous stricture, percutaneous angioplasty is a safe and useful procedure, but to maintain long-term central venous patency, repeated interventions are required

    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.

    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 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

    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

    Rouse, Nicole C; Maibach, Howard I

    2016-01-01

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

    To determine anatomic and hemodynamic echocardiographic predictors for patent ductus arteriosus (PDA) device vs coil closure. Seventy-six patients who were referred for elective transcatheter PDA closure were enrolled in the study. All patients underwent full echocardiogram including measurement of the PDA pulmonary end diameter, color flow width and extent, peak and end-diastolic Doppler gradients across the duct, diastolic flow reversal, left atrial dimensions and volume, left ventricular sphericity index, and volumes. The study group was subdivided into 2 subgroups based on the mode of PDA closure whether by coil (n = 42) or device (n = 34). Using univariate analysis there was a highly significant difference between the 2 groups as regard the pulmonary end diameter measured in both the suprasternal and parasternal short-axis views as well as the color flow width and color flow extent (P closure group had statistically significant higher end-systolic and end-diastolic volumes indexed, left atrial volume, and diastolic flow reversal. Receiver operating characteristic curve analysis showed a pulmonary end diameter cutoff point from the suprasternal view > 2.5 mm and from parasternal short-axis view > 2.61 mm to have the highest balanced sensitivity and specificity to predict the likelihood for device closure (AUC 0.971 and 0.979 respectively). The pulmonary end diameter measured from the suprasternal view was the most independent predictor of device closure. The selection between PDA coil or device closure can be done on the basis of multiple anatomic and hemodynamic echocardiographic variables. © 2017 Wiley Periodicals, Inc.

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

    The aim of this study was to develop a method for estimating DMSA SPECT renal function on each renal pole in order to evaluate the effect of percutaneous nephrolithotripsy by focusing the measurements on the region through which the percutaneous approach is performed. Twenty patients undergoing percutaneous nephrolithotripsy between November 2010 and June 2012 were included in this study. Both Planar and SPECT-DMSA studies were carried out before and after nephrolithotripsy. The effect of percutaneous nephrolithotripsy was evaluated by estimating the total renal function and the regional renal function of each renal pole. Despite PCNL has been previously reported as a minimally invasive technique, our results showed regional renal function decreases in the treated pole in most patients, affecting the total renal function in a few of them. A quantification method was used for estimating the SPECT DMSA renal function of the upper, inter polar and lower renal poles. Our results confirmed that total renal function was preserved after nephrolithotripsy. Nevertheless, the proposed method showed that the regional renal function of the treated pole decreased in most patients (15 of 20 patients), allowing us to find differences in patients who had not shown changes in the total renal function obtained from conventional quantification methods. In conclusion, a method for estimating the SPECT DMSA renal function focused on the treated pole enabled us to show for the first time that nephrolithotripsy can lead to a renal parenchymal damage restricted to the treated pole.

    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.

    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.)

    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

    We aimed to assess the association between arterial hypertension and bleeding in patients undergoing percutaneous coronary intervention (PCI). The impact of arterial hypertension on bleeding risk of patients with coronary artery disease undergoing PCI is unknown. This study included 14,180 patients who underwent PCI. Bleeding was defined using the Bleeding Academic Research Consortium (BARC) criteria. Arterial hypertension was defined as treatment with antihypertensive drugs or a systolic blood pressure >140 mm Hg and/or diastolic blood pressure value >90 mm Hg documented on at least 2 occasions. The primary outcome was bleeding rate within 30 days of PCI. Overall, 11,066 patients (78.0%) had arterial hypertension. Bleeding events occurred in 1,232 patients with arterial hypertension and 278 patients without arterial hypertension (11.1% vs 8.9%; odds ratio [OR] = 1.28, 95% confidence interval [CI] 1.11-1.46, P arterial hypertension and 175 patients without arterial hypertension (6.6% vs 5.6%: OR = 1.19 [1.01-1.41], P = 0.049). Non-access-site bleeding occurred in 502 patients with and 103 patients without arterial hypertension (4.5% vs 3.3%; OR = 1.39 [1.12-1.72], P = 0.003). After adjustment, arterial hypertension was significantly associated with any bleeding (adjusted OR = 1.41 [1.19-1.67], P arterial hypertension increased the risk of non-access-site bleeding (P = 0.002), whereas systolic blood pressure at the time of PCI increased the risk of access site bleeding (P = 0.018). Arterial hypertension is associated with increased risk of bleeding during PCI procedures. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

    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.

    Cangrelor is an intravenously administered P2Y 12 receptor antagonist with very fast, potent, and quickly reversible action. In the CHAMPION PHOENIX trial, cangrelor provided an improved anti-ischemic protection compared with clopidogrel, without increasing the risk of severe bleeding. Cangrelor is currently approved by drug regulating authorities for patients undergoing percutaneous coronary intervention (PCI) without prior treatment with a P2Y 12 receptor antagonist and not receiving a glycoprotein IIb/IIIa inhibitor, while its use is endorsed with a class IIb recommendation by the European Society of Cardiology guidelines. Several subanalyses of CHAMPION PHOENIX trial have tried to elucidate the role of cangrelor in PCI, including its usefulness during a 2-hour landmark analysis, impact on intraprocedural stent thrombosis, and reduction in myocardial infarction (MI) rate. The influence of gender, geographic region, access site, and bivalirudin use on cangrelor's effects has also been reported. In patients with ST elevation MI and in clinical scenarios of disturbed absorption of oral antiplatelet agents or in need of an intravenous agent, cangrelor may surpass oral agents' drawbacks. Transitioning to an oral agent is mandatory following cangrelor infusion discontinuation, although ticagrelor may be administered earlier without any pharmacodynamic interaction. Nevertheless, the clinical role of cangrelor in conjunction with administration of prasugrel or ticagrelor remains unclear. Accruing real-life experience is expected to improve our understanding of cangrelor's role in everyday clinical practice.

    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

  13. 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.

    Purpose: The aim of the present study was to record and identify the frequency of complications following percutaneous nephrostomy, replacement of nephrostomy drains and percutaneous insertion of ureteral endoprostheses.Methods: During a 10-year period 341 patients were referred to our department with indications for percutaneous nephrostomy and/or percutaneous insertion of a ureteral endoprosthesis, and a total of 1036 interventional procedures were performed (nephrostomy, catheter change, stenting).Results: There were three major complications (0.29%): two patients died during the first 30 days after the procedure, due to aggravation of their condition caused by the procedure, and one patient had retroperitoneal bleeding requiring surgery. There were 76 complications of intermediate severity (7.33%): catheter or stent displacement (n = 37, 3.57%) catheter occlusion (n = 18, 1.73%), hematuria (n = 12, 1.16%), and urinary tract infection (n = 9, 0.87%). The 55 minor complications (5.3%) comprised inflammation of the skin at the site of insertion of the percutaneous catheter.Conclusion: The small number of complications observed during acts of interventional uroradiology prove transcutaneous manipulations to be safe medical procedures

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

    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

    The sphenopalatine ganglion (SPG) has been assumed to be involved in the genesis of several types of facial pain, including Sluder's neuralgia, trigeminal neuralgia, persistent idiopathic facial pain, cluster headache, and atypical facial pain. The gold standard treatments for SPG-related pain are percutaneous procedures performed with the aid of fluoroscopy or CT. In this technical note the authors present, for the first time, an SPG approach using the aid of a neuronavigator.

    The percutaneous treatment of pericardial effusion resulting in cardiac tamponade has undergone an evolution in recent years with the use of less invasive drainage techniques in selected cases. To determine optimal therapy modalities for oncology patients with malignant pericardial tamponade (MPT), the authors review their institutional experience with percutaneous needle puncture routes, means of imaging-guided drainage and percutaneous management of the pericardial fluid effusion (pericardial sclerosis and balloon pericardiotomy). Advantages and limits of the percutaneous techniques will be compared to the surgical treatment. (orig.)

    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.

    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.

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

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

    Frederik M. Zimmermann, MD

    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.

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

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

    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

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

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

    The large number of pace-makers introduced transvenously has resulted in increasing the number of complications, amongst which infections and dislocations are prominent. It is usually necessary to remove the electrode, which can be attempted percutaneously by using a Dormia basket, a loop or forceps. Amongst the complications of this procedure are tears to the myocardium, with the risk of pericardial tamponade, or tears of the tricuspid valve leading to tricuspid insufficiency. Consequently, thoracic surgical intervention should be available if necessary. Four successful procedures are described. (orig.) [de

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

    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

    Renal artery stenosis is a frequent complication of kidney transplantation (10%). Percutaneous transluminal angioplasty (PTA) has recently been proposed as a potential therapeutic procedure. Twelve transplant patients with arterial stenosis underwent PTA. The procedure was successful in 10 cases (83.3%). Restenosis occurred in 2 patients (16.7%); both of them underwent PTA successfully. No complications occurred. A considerable improvement in glomerular filtration rate and a reduction in high blood pressure were observed in all patients after successful PTA. The authors belive PTA to be the therapy of choice in the treatment of arterial stenoses in kidney transplant patients

    OBJECTIVES: The aim of this study was to assess the safety of the concurrent administration of a clopidogrel and prasugrel loading dose in patients undergoing primary percutaneous coronary intervention. BACKGROUND: Prasugrel is one of the preferred P2Y12 platelet receptor antagonists for ST-segment.......62, p = 0.36). CONCLUSIONS: This observational, nonrandomized study of ST-segment elevation myocardial infarction patients suggests that the administration of a loading dose of prasugrel in patients pre-treated with a loading dose of clopidogrel is not associated with an excess of major bleeding events...

    Full Text Available 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

    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.

    Full Text Available Abstract Objective: To evaluate the percutaneous transhepatic approach to the treatment of biliary strictures in pediatric patients undergoing liver transplantation. Materials and Methods: This was a retrospective study of data obtained from the medical records, laboratory reports, and imaging examination reports of pediatric liver transplant recipients who underwent percutaneous transhepatic cholangiography, because of clinical suspicion of biliary strictures, between 1st September 2012 and 31 May 2015. Data were collected for 12 patients, 7 of whom were found to have biliary strictures. Results: In the 7 patients with biliary strictures, a total of 21 procedures were carried out: 2 patients (28.6% underwent the procedure twice; 3 (42.8% underwent the procedure three times; and 2 (28.6% underwent the procedure four times. Therefore, the mean number of procedures per patient was 3 (range, 2–4, and the average interval between them was 2.9 months (range, 0.8–9.1 months. The drainage tube remained in place for a mean of 5.8 months (range, 3.1–12.6 months. One patient presented with a major complication, hemobilia, which was treated with endovascular embolization. Clinical success was achieved in all 7 patients, and the mean follow-up after drain removal was 15.4 months (range, 5.3–26.7 months. Conclusion: The percutaneous transhepatic approach to treating biliary strictures in pediatric liver transplant recipients proved safe, with high rates of technical and clinical success, as well as a low rate of complications.

    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.

    While routine renal imaging following ureteroscopy for urinary calculi has been recommended to screen for asymptomatic "silent" obstruction, the rate of silent obstruction following percutaneous nephrolithotomy (PCNL) remains poorly defined, and no consensus recommendations exist on routine postoperative imaging. At our institution, we sought to assess the incidence of silent hydronephrosis (SH), as a screen for obstruction, following PCNL. The records of all 162 patients who met study inclusion criteria were reviewed. Of this group, 112 patients presented for their scheduled renal ultrasonography 4 - 6 weeks following stent removal to screen for SH. Asymptomatic patients found to have ultrasonographic evidence of hydronephrosis were further analyzed. SH was noted in 16% (18/112) of patients. Two required subsequent ureteroscopic stone extraction (1.8%), one of which also underwent endoureterotomy for a ureteral stricture. Four patients (22%) had stable hydronephrosis and declined functional imaging, 2 patients (11%) had a known partial ureteropelvic junction obstruction and declined intervention. SH resolved spontaneously in 50% (9/18) with a mean time to resolution of 6.3 months. There was no difference in stone complexity based on Guy's stone score between groups, 2.8 (± 0.92) vs. 2.4 (± 1.03), p = 0.34. Although not statistically significant, patients with SH were more likely to have had residual stone fragments postoperatively, 39% (7/18) vs. 19% (18/94), p = 0.067. SH following, PCNL was identified in 16% of this screened population, with the majority requiring no intervention. However, SH may be attributed to residual stone or stricture, which may have been otherwise unrecognized in up to 2% of patients undergoing PCNL. Consideration should be given for routine postoperative ultrasound to screen for silent obstruction following PCNL.

    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.

    Acute cerebrovascular accident (CVA) after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) and coronary artery disease (CAD) is associated with high morbidity and mortality. Nationwide Inpatient Sample from 1998 to 2008 was utilized to identify 1,552,602 PCIs performed for ACS and CAD. We assessed temporal trends in the incidence, predictors and prognostic impact of CVA in a broad range of patients undergoing PCI. The overall incidence of CVA was 0.56% (95% confidence interval (CI), 0.55%–0.57%). The incidence of CVA remained unchanged over the study period (adjusted p for trend = 0.2271). The overall mortality in the CVA group was 10.76% (95% CI, 10.1%–11.4%). The adjusted odds ratio (OR) of CVA for in-hospital mortality was 7.74 (95% CI, 7.00–8.57; p<0.0001); this remained high but decreased over the study period (adjusted p for trend <0.0001). Independent predictors of CVA included older age (OR, 1.03, 95% CI, 1.02–1.03; p<0.0001), disorder of lipid metabolism (OR, 1.31, 95% CI, 1.24–1.38; p<0.001), history of tobacco use (OR, 1.21, 95% CI, 1.10–1.34; p=0.0002), coronary atherosclerosis (OR 1.56, 95% CI, 1.43–1.71; p<0.0001), and IABP use (OR 1.39, 95% CI, 1.09–1.77; p=0.0073). A nomogram for predicting the probability of CVA achieved a concordance index of 0.73 and was well calibrated. In conclusion, the incidence of CVA associated with PCI has remained unchanged from 1998–2008 in face of improved equipment, techniques and adjunctive pharmacology. The risk of CVA associated in-hospital mortality is high; however, this risk has declined over the study period. PMID:24952927

    in their symptoms and patients who were inoperable because of any of the following reasons: (1) Exhausted conventional treatment options, (2) technical and anatomical contraindications to conventional treatment, (3) medical comorbidities precluding surgery, (4) patient refusal, (5) recurrent tumors, and (6) advanced tumor stage. Conventional Treatment has been defined as surgical resection, radiotherapy, and/or chemotherapy, although the patient eligibility for each treatment may vary. Patients with the following were excluded: (1) Severe coagulopathy, (2) heart, renal, or liver failure, (3) lesions within 1 cm of gall bladder, hilum, bowel wall, and major blood vessels, (4) patient with any metal implant, (5) patients in sepsis, and (6) tumor adjacent to structures at risk (main bile ducts, pericardium, stomach, or bowel). The duration of procedure as well as ablation of tumor free margin was significantly related to the size of the tumor. As the size of tumor increased, duration of procedure increased significantly. A good tumor-free margin also needs to be ablated for optimum results as it prevents residual tumors and recurrences in the future. We observed that tumors sized <3.1 cm were optimal in this regard. Most common adverse event in postprocedure period was pain in and around ablation site. Post-RFA syndrome is also a common and benign self-limiting side effect. Patient counseling and proper selection of patients in the early stages of malignancy can enhance the efficacy of the procedure and patient satisfaction. Percutaneous image-guided RFA is an option in patients where most other tumor management modalities have been exhausted or rejected. RFA may not be free from side effects such as postablation syndrome, pain, and there may be other serious complications such as bleeding, but based on our observations, percutaneous image-guided RFA of tumors is a safe palliative and therapeutic treatment option.

    Full Text Available The study has been designed to compare the outcome of percutaneous nephrolithotomy with (Group A or without nephrostomy tube (Group B for the management of renal stone disease. JJ stents were given to all cases of both groups. Comparison of outcome between groups shows that urinary leakage time was significantly longer in Group B than that in Group A (24.0 ± 6.2 vs 7.3 ± 3.9 hours;  p<0.001. Visual analogue pain score was also significantly high in Group B than in Group A (4.7 ± 0.8 vs 2.4 ± 0.5; p<0.035. Patients in Group B stayed in hospital on an average 4 days, while the Group A patients stayed in hospital on an average 2.5 days (p<0.029. The mean hemoglobin decrease in 24 hours in Group B and in Group A (0.5 ± 0.4 and 0.5 ± 0.4 respectively did not show any significant difference (p<0.895. In conclusion, percutaneous nephrolithotomy without nephrostomy tube can be practiced in the management of selective cases of renal stones diseases.

    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.

  2. Percutaneous treatment of intervertebral disc herniation.

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

    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.

    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

    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.

    Perirenal hematoma after a renal biopsy is a common complication that usually resolves spontaneously, but this rarely requires transfusions or surgical/radiological intervention. We report here on a case of a renal perforating artery that was mistaken for renal arterial bleeding in a 53-year-old woman who was complicated with perirenal hematoma after undergoing a percutaneous renal biopsy. On the color and pulsed wave Doppler ultrasonography, linear blood flow was seen in the perirenal hematoma, which extended perpendicularly from the renal parenchyma into the perirenal space, and this linear blood flow exhibited an arterial pulse wave. On CT angiography, the renal perforating artery was demonstrated as a curvilinear vessel coursing tangentially to the renal margin and we decided that it was a pseudolesion caused by the renal perforating artery. A renal perforating artery may be mistaken for renal arterial bleeding after a percutaneous renal biopsy. A renal perforating artery and arterial bleeding can be differentiated by the location and shape seen on a color Doppler examination and the pulse waves characteristics

    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.

    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

    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.

  12. Use of clopidogrel in the reduction of myocardial damage during percutaneous coronary intervention

    Full Text Available Arijit Dasgupta, Debabrata MukherjeeGill Heart Institute, University of Kentucky, Lexington, KY, USAAbstract: It is estimated that approximately a quarter of patients undergoing coronary intervention may have significant post-procedural creatinine (CK/creatinine kinase myocardial band (CK-MB elevations and approximately half may have post-procedural troponin elevations. Current data suggest that periprocedural infarction is associated with short-, intermediate-, and long-term adverse outcomes, most notably mortality. This review examines the role of clopidogrel in decreasing periprocedural myonecrosis following percutaneous coronary intervention (PCI. Clopidogrel is an important pharmacologic agent used to reduce myocardial infarction post-coronary intervention as assessed directly by the evaluation of cardiac biomarkers and indirectly by the evaluation of short-term ischemic events. The optimal dose of clopidogrel is considered to be at least 300 mg given 6 to 15 hours prior to PCI but there is considerable evidence to suggest that a loading dose of 600 mg given 2 to 6 hours prior to PCI may be more efficacious in limiting post-coronary intervention events. The benefit obtained from clopidogrel appears independent of and incremental to that of other antiplatelet and antithrombotic agents used during and after coronary intervention.Keywords: percutaneous coronary intervention, myonecrosis, clopidogrel, antiplatelet agents, myocardial infarction

    To evaluate expansion of image-guided interventional cryoablation techniques usually employed for pain management to address the feasibility, safety, and efficacy of treatment for a urologic condition with otherwise limited treatment options, premature ejaculation (PE). Prospective institutional review board approval was obtained, and 24 subjects with PE were enrolled. All patients underwent unilateral percutaneous computed tomography-guided cryoablation of the dorsal penile nerve (DPN). Postprocedural intravaginal ejaculatory latency times (IELTs) and PE Profile (PEP) results served as outcome variables. In addition, subjects were asked whether they would have the procedure done again based on their experience at the 180- and 360-day marks. The technical success rate was 100%. Baseline average IELT was 54.7 seconds ± 7.8 (n = 24), which increased to a maximum of 256 seconds ± 104 (n = 11; P = .241) by day 7 and decreased to 182.5 seconds ± 87.8 (n = 6; P = .0342) by day 90. The mean IELT remained at 182.5 seconds ± 27.6 at day 180 (n = 23; PIELTs significantly improved at 180 and 360 days, and 83% of subjects reported that they would undergo the procedure again if given the same opportunity. There were no procedure-related complications. CT-guided percutaneous unilateral cryoablation of the DPN is a feasible, safe, single-day outpatient procedure for the treatment of symptomatic PE.

    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.

    Until a few years ago diagnosis of congenital saccular intrahepatic dilatation of bile ducts (Caroli's syndrome) was established intraoperatively or postmortem only. Intravenous cholangiocholecystography and intraoperative cholangiography will often furnish insufficient information. Preoperative diagnosis has become possible for some time now via percutaneous transhepatic and endoscopic retrograde cholangiography. Basing on a case history it is shown that non-invasive diagnosis of Caroli's syndrome has now become possible without the risk of a possible life-threatening cholangitis relapse. This is the merit of new techniques such as sonography and computerized tomography. (orig.) [de

    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.

    Endovascular aneurysm repair (EVAR) with percutaneous femoral access (PEVAR) has several potential advantages. Morbidly obese (MO) patients present unique anatomical challenges and have not been specifically studied. This study examines the trends in the use of PEVAR and its surgical outcomes compared with open femoral cutdown (CEVAR) in MO patients. The American College of Surgeons National Surgical Quality Improvement Program files for the years 2005 to 2013 were reviewed. The study included all MO patients (body mass index [BMI] ≥40 kg/m 2 ) undergoing EVAR. Patients were categorized as having CEVAR if they had any one of 11 selected Current Procedural Terminology (American Medical Association, Chicago, Ill) codes describing an open femoral procedure. The PEVAR group included any remaining patients who had only codes for EVAR and endovascular procedures. Linear correlation was used to evaluate temporal trends in the use of PEVAR among MO patients. Baseline comorbidities and surgical outcomes were compared between the PEVAR and CEVAR groups using χ 2 tests or t-tests. There were 833 MO patients (470 CEVAR and 363 PEVAR) constituting 3.0% of all patients undergoing EVAR. The use of PEVAR in MO patients significantly increased from 27.3% of total EVARs in the years 2005 to 2006 to 48.6% in 2013 (P = .039). The two groups had similar baseline characteristics, including age, BMI, comorbidities, and emergency procedures, except for history of severe chronic obstructive pulmonary disease (29.6% CEVAR vs 22.6% PEVAR; P = .024). PEVAR patients had shorter duration of anesthesia (244 vs 260 minutes; P = .048) and shorter total operation time (158 vs 174 minutes; P = .002). PEVAR patients had significantly decreased wound complications (5.5% vs 9.4%; P = .039). There was a trend towards PEVAR patients being more likely to be discharged home than to a facility (93.6% vs 87.8%; P = .060). There was no difference in any other complication or mortality.

    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)

    Practice guidelines recommend dual antiplatelet therapy with aspirin and clopidogrel for patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS) regardless of in-hospital management strategy. Prasugrel-a thienopyridine adenosine diphosphate receptor antagonist that provides...... higher and less variable levels of platelet inhibition than clopidogrel-has demonstrated benefit when used to treat ACS patients undergoing percutaneous coronary intervention. However, the optimal approach to antiplatelet therapy for high-risk, medically managed NSTE ACS patients remains uncertain...... revascularization procedures for their index event. Patients will be randomly allocated to prasugrel + aspirin versus clopidogrel + aspirin for a median duration of 18 months.

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

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

    In recent years, the radial artery (RA) has become an alternative vascular access site for percutaneous coronary procedures, and the ulnar artery (UA) is another possibility. The objective of this study was to investigate the anatomy of the forearm arteries with ultrasound (US) and to evaluate the effect of the anatomy of the right RA (RRA) on the outcomes of transradial coronary procedures. The 638 patients undergoing transradial coronary procedures were examined with US for measurement of the diameters of the forearm arteries and determination of their anatomical abnormalities before the procedures. The next day the incidence of RA occlusion was recorded. The diameters of the radial and ulnar arteries were similar (P>0.05). The procedure time was longer in patients with anatomical abnormalities (Pforearm arteries of Chinese people are similar. The small diameter and anatomical abnormalities of the RRA could result in longer procedure time, more incidence of procedure failure and RA occlusion.

    Full Text Available The presented article focuses on the important matters of development of intraoperative and postoperative complications in patients with urolithiasis undergoing percutaneous operative treatment for coral calculus of a solitary or sole functioning kidney. Complications of percutaneous X-ray-endoscopic operations in these patients always require careful medical and diagnostic approach, as they can lead to oppression of an already impaired solitary kidney function and, as a consequence, can have life-threatening nature. They are divided into two groups: intraoperative and postoperative complications. Intraoperative complications include: bleeding, damage of the renal pelvis in the course of creating of puncture access, perforation of internal organs, loss of stroke. Postoperative complications include: development of acute inflammation in a single kidney, bleeding, urinoma or hematoma development, progression of renal failure, leave of residual concretions, organ loss. There is a sufficient amount of data on the development of complications after percutaneous endoscopic surgeries in the literature, but very few works are devoted to a solitary kidney matter. The object of this study was the group of patients with urolithiasis, coral nephrolithiasis by a solitary or a single functioning kidney, who were on treatment in the urology department of the N.I. Pirogov City Clinical Hospital No. 1 from January 2007 to July 2014. All patients underwent percutaneous operative treatment for the removal of coral calculi.
