OBJECTIVE To evaluate long-term clinical performance and angiographic patency of automated proximal venous anastomoses following clampless coronary artery bypass (C-CAB). METHODS Observational study in patients submitted for isolated C-CAB and at least one proximal aortosaphenous anastomosis performed with an automated connector (Cardica PAS-Port) including 152 consecutive patients (165 devic...

BACKGROUND Extracranial-to-intracranial (EC-IC) arterial bypass is a technically demanding procedure used to treat complex cerebral artery diseases. The indications, proper surgical techniques, and outcomes of this procedure have been under debate over the recent decades. METHODS Between January 2004 and December 2012, 28 patients, including patients with cerebral artery occlusion, intracrani...

OBJECTIVE To evaluate the application of a microsurgical two-layer anastomosis technique in the treatment of failed vasectomy reversal. METHODS A microsurgical two-layer anastomosis was used in a series of 24 patients with confirmed anastomotic obstruction after previous vasectomy reversal. The patients were followed up for 9 months to 6 years, and the efficacy of the procedure was evaluated ...

AIM The aim of this paper was to study the impact of risk factors on long-term results of above-knee prosthetic femoropopliteal bypass for critical ischemia. METHODS One hundred and eleven consecutive operations (108 patients) were done between January 1990 and December 2001. All cases were prospectively registered. The patient characteristics were subjected to univariate analysis using the l...

A review of randomized controlled trials and observational cohort studies found in the PubMed, Embase, Cochrane databases through April 2021. In 26 comprising 26,845 patients who were treated by uncoated balloon (UCB) (17,770) or drug-coated (DCB) (9075) angioplasty for lower extremity peripheral arterial disease (LE-PAD), DCB was associated with significantly vessel restenosis, reduction major...

AIMS Preliminary reports indicate that sirolimus-eluting stents reduce the risk of restenosis after percutaneous infrapopliteal artery revascularization. We conducted a prospective, randomized, multi-centre, double-blind trial comparing a polymer-free sirolimus-eluting stent with a placebo-coated bare-metal stent in patients with either intermittent claudication or critical limb ischaemia who h...

arteriovenous fistulae traditionally have been placed in the upper extremity. experience with groin hemodialysis access has been discouraging because of high infection rates and associated limb amputation. the aim of this study was to determine infection rates, patency rates, and possible predictive factors for prosthetic thigh angioaccess outcomes in our hemodialysis patient population. a pros...

PURPOSE To report the long-term follow-up results of peripheral cutting balloon incision and dilatation (PCBID) after failed high-pressure balloon dilatation in patients with benign ureteral and biliary strictures. MATERIALS AND METHODS The study included 9 patients (5 males and 4 females) who underwent successful PCBID procedures. Of these, 4 patients had biliary strictures; 2 of them had ch...

Vasectomy is a simple and reliable method of male contraception. A growing number of men after vasectomy request vasectomy reversal due to various reasons. The pregnancy rate is lower than the patency rate after vasovasostomy and the pregnancy rate is time dependent. In this study, we evaluated the influence of reproductive tract obstruction on expression of epididymal proteins and their restor...

BACKGROUND Stenting has been shown to improve patency after femoral artery revascularization compared with balloon angioplasty. Limited data are available evaluating endovascular treatment for obstructive lesions of the popliteal artery. METHODS AND RESULTS This prospective, randomized, multicenter trial compared primary nitinol stent placement to percutaneous transluminal balloon angioplasty...
