The US National Library of Medicine and National Institutes of Health manage PubMed.gov which comprises of more than 29 million records, papers, reports for biomedical literature, including MEDLINE, life science and medical journals, articles, reviews, reports and books.
BioPortfolio aims to cross reference relevant information on published papers, clinical trials and news associated with selected topics - speciality.
For example view all recent relevant publications on Epigenetics and associated publications and clincial trials.
The growth rate of abdominal aortic aneurysm (AAA) is used as a surrogate marker of rupture risk. Its determination is based on maximum diameter increase. However, AAA expansion presents a significant spatial variability. We aim to record the spatial distribution of regional wall surface expansion.
Vascular surgeons have a central role in managing peripheral artery disease (PAD). This study assessed their knowledge, attitudes, and behaviours regarding pharmacologic risk reduction in PAD and results were compared to a similar 2004 survey conducted by our group.
To assess the ability of a novel, automated CE marked vascular early warning system (VEWS) device to detect peripheral arterial disease in patients with incompressible ankle arteries and non-measurable ankle brachial pressure index (ABPI) secondary to diabetes.
Deep vein thrombosis (DVT) is associated with significant complications, including the development of post-thrombotic syndrome (PTS). Traditional management is with oral anticoagulation, but the endovascular techniques of catheter-directed thrombolysis (CDT), pharmaco-mechanical thrombolysis and venous stenting are now increasingly used. This study aims to review the evidence for these endovascular techniques in the management of acute lower limb DVT, and their role in the reduction of complications such as...
Primary leiomyosarcoma of the inferior vena cava (IVC) is a rare soft tissue sarcoma. Techniques for caval reconstruction after tumor resection vary widely. Our single-center experience serves as one of the largest reviews of caval reconstruction using polytetrafluoroethylene (PTFE) interposition grafts published in the past 10 years.
Optimal stenting strategy for long femoropopliteal artery lesions still remains undefined. Longer stent length has been shown to be associated with increased risk of restenosis. We sought to compare the efficacy of spot versus long stenting in the treatment of femoropopliteal artery disease.
Carotid endarterectomy (CEA) is deemed to restore the blood flow of the carotid and ophthalmic arteries in patients with carotid artery stenosis. However, specific changes in visual function before and after CEA are not well understood; hence, this observational study aimed to investigate the functional and structural changes in vision after CEA in those patients.
Chronic total occlusion (CTO) of femoropopliteal artery (FP) continues to be a lesion subset where maintaining long-term patency after endovascular treatment is challenging. We evaluated the efficacy of cutting balloon angioplasty (CBA) for de novo FP-CTOs in patients with symptomatic lower limb ischemia.
Routine laboratory testing to rule out myocardial infarction (MI) after carotid endarterectomy (CEA) is common in many centers. Its utility in this patient population has not been thoroughly investigated. We hypothesize that routine testing for MI in post-CEA patients is of low-yield and not cost-effective.
The aim of this study is to compare two groups of patients treated for great saphenous vein (GSV) reflux with open surgical saphenofemoral ligation (SFL) and EndoVenous Laser Ablation (EVLA) MATERIALS AND METHODS: Consecutive patients with primary unilateral GSV reflux undergoing EVLA treatment since 2014 were enrolled, and another series of patients treated with SFL was considered. The patients were stratified according to treatment and the results were compared using the propensity score (1:1). The covari...
Renal arteriovenous fistula with renal artery aneurysms and dilated renal veins presents as an infrequent lesion. Endovascular therapy has recently been considered the first-line treatment for these conditions. We report a case of a patient with idiopathic renal arteriovenous fistula concomitant with multiple renal artery aneurysms that was successfully treated by the placement of a covered stent.
The aim of this study was to investigate the effect of preexisting calcification in the inflow artery on maturation and flow volume of an arteriovenous fistula (AVF).
While autogenous venous graft is preferable in below the knee bypass surgery for patients in critical limb ischemia, some 20% of patients will have no suitable vein for grafting, compelling a resort to artificial graft materials. Retrospective sub-group analyses within published studies comparing heparin-bonded PTFE with crude PFTE graft in below the knee bypass suggest that heparin-bonded graft offers superior long-term patency rates, but this has not been prospectively verified in patients with critical l...
To evaluate the short-term outcomes of percutaneous mechanical thrombectomy (PMT) in patients with acute lower limb ischemia (ALI) and to analyze the effect of ALI of different etiologies on the limb salvage.
Neutrophil-to-lymphocyte ratio (NLR) has recently emerged as a useful predictor of cardiovascular risk and adverse outcomes. According to previous studies, an NLR > 5 has the highest sensitivity and specificity for postoperative morbidity and mortality in cardiovascular disease. This study aims to evaluate the NLR in cases of unruptured (uAAA) and ruptured (rAAA) infrarenal abdominal aortic aneurysm (AAA) and to assess the role of NLR as a prognostic marker of 30-day mortality in patients with unruptured an...
Visceral aneurysms are rare entities, with a reported incidence of 0.01-2%. Fibromuscular dysplasia is a non-atherosclerotic, non-inflammatory artery disease which may predispose to aneurysmal degeneration. Schizophrenia has been linked to an increased cardiovascular risk because of the influence of traditional and disease specific risk factors. We report the case of a 44-year old male schizophrenic patient presenting with a ruptured giant aneurysm of superior mesenteric artery, managed by mesenteric ligati...
Successful endovascular repair of thoracic aorta for type B aortic dissection requires correct stent-graft sizing, particularly of distal landing zone which is mainly based on operator experience. The present study aimed to quantitatively define proximal-to-distal tapering of descending thoracic aortic diameter and its consistency.
To describe a single-center experience with the Conformable GORE Thoracic Endoprosthesis (C-TAG) with Active Control System, specifically designed to evaluate the accuracy of proximal and distal deployment and its capability to adapt to the aortic wall.
Causes of acute limb ischemia are classically mainly emboli and thrombosis. Nicolau syndrome, is a very rare complication of intramuscular injection presumed to be related to the inadvertent intravascular injection. It was first reported following intramuscular injection of bismuth salt, but it can occur as a complication of various other drugs. Acute limb ischemia is one of its severe outcome but is rarely encountered and reported.
The aim of this study is to examine the efficacy and safety of Angiojet rheolytic thrombectomy for the treatment of subacute deep venous thrombosis (DVT) in lower limbs.
Drug abuse may affect lower extremity vessels due to ischemia following intra-arterial injections, vasospasm, arterial and venous pseudoaneurysms, arteriovenous fistulae, vasculitis and complicated abscesses. Little is known about the outcomes of Lower Extremity Bypass (LEB) for peripheral arteries disease (PAD) in patients with a history of drug abuse disorder. The aim of this study is to evaluate the outcomes of LEB in this patient population.
Spinal cord ischemia is one of the most unpredictable and feared complication following open surgical or endovascular thoracic aortic repair. Protection of collateral network branches that contribute blood supply to spinal cord is fundamental in the prevention of this catastrophic condition. We report the case of a patient who underwent emergent endovascular treatment for a type B aortic dissection complicated by rupture of the false lumen, with intentional coverage of the left subclavian artery without rev...
Retrograde type A dissection (RTAD) is a serious complication after ascending aorta involved endovascular repair (AAIER). We here report our surgical approach to this serious complication.
