BACKGROUND AND PURPOSE The rate of PICA occlusion after flow-diverting stent placement for vertebral and vertebrobasilar artery aneurysms is not known. The purpose of this study is to determine the medium-term rate of PICA patency and risk factors for occlusion after such aneurysm treatment. MATERIALS AND METHODS Patients were identified who had vertebral or vertebrobasilar artery aneurysms a...

OBJECTIVE To compare the efficacy of suprapapillary and transpapillary methods of transhepatic biliary metallic stent placement in malignant biliary strictures and to specify the indications of each method applied. MATERIALS AND METHODS Stents were placed in 59 patients. Strictures were categorized as type A (within 3 cm of the ampulla, n = 27), type B (over 3 cm from ampulla, n = 7), type C ...

BACKGROUND The prevalence and treatment of peripheral arterial disease in the Caribbean is not well documented. The aim of this study was to review the results from a small hospital in the Caribbean. METHODS One-hundred and eight infra-inguinal arterial reconstructions on 90 patients were retrospectively reviewed Patients were classified according to the categories suggested by the Ad Hoc Com...

OBJECTIVES To evaluate the safety and efficacy of endovascular intervention with angioplasty and stent placement in patients with transplant renal artery stenosis. METHODS All patients diagnosed with transplant renal artery stenosis and graft dysfunction or resistant systemic hypertension who underwent endovascular treatment with stenting from February 2011 to April 2016 were included in this...

BACKGROUND To improve the longterm outcome after CABG, several strategies have been used using arterial conduits. Our 20 years experience with the right gastroepiploic artery (GEA) graft was evaluated. METHODS AND RESULTS In 1352 patients having CABG with the GEA graft, (1092 men, mean 63 years, 99% multivessel disease, and mean EF 0.51), internal thoracic artery, saphenous vein, and radial a...

BACKGROUND Laparoscopic salpingostomy is a well-established treatment for patients with tubal pregnancy who desire to retain fertility. Another approach that preserves the fallopian tube is medical treatment. We compared systemic methotrexate and laparoscopic salpingostomy in the treatment of tubal pregnancy. Outcome measures were treatment success, tubal preservation, and homolateral tubal pat...

BACKGROUND Coronary artery bypass graft (CABG) surgery is the standard of care in the treatment of advanced coronary artery disease, and its long-term results are affected by the failure of bypass grafts. The aim of the present study was to evaluate the early patency rate in coronary bypass grafts. METHODS A total of 107 consecutive patients who underwent CABG were included in this study. Ear...

OBJECTIVES Composite grafting using the right internal thoracic artery (RITA) is occasionally performed when the in situ RITA does not have sufficient length to reach the target vessel. In this study, we assessed the clinical and angiographic outcomes of coronary artery bypass grafting (CABG) with V-composite grafting (defined as a distance between the proximal anastomosis of the RITA and the a...

Keywords Arteriovenous graft Hemodialysis Thrombosis Vascular access failure is known as a principal cause of morbidity of end stage renal disease (ESRD) patients. The major reason for vascular access failure is the neointimal hyperplasia which leads to venous thrombosis and stenosis. The efficacy of different pharmacological therapies has been studied in increasing the vascular access patency ...

INTRODUCTION The Authors reports their experience with the use of femoro-femoral cross-over bypass graft in the management of acute lower limb ischaemia. PATIENTS AND METHODS Fourteen femoro-femoral bypass graft were performed for acute lower limb ischaemia due to unilateral thrombosis of iliac and femoral artery in 8 cases, late unilateral occlusion of a branch of previous aortobifemoral byp...
