Long-term graft outcome after renal arterial reconstruction during living related kidney transplantation.

Background/objectives: The aim of this retrospective study was to evaluate the repair of vascular variations/pathologies in living donor kidney transplantations in a single centre over a 15-year period.

Methods: Between 01/1997 and 05/2012, 338 living donor renal transplantations were performed in the Department for Endovascular and Vascular Surgery, University of Düsseldorf, Germany. Twenty-four of them showed disorders, like multiple renal arteries (MRA), atherosclerotic stenosis or fibromuscular dysplasia (FMD) needing vascular repair before transplantation.

Time is brain?--Surgical revascularization of acute symptomatic occlusion of the internal carotid artery up to one week.

Background: Clinical outcome and surgical success rate of open surgical reconstruction for acute symptomatic internal carotid artery (ICA) occlusion up to 1 week after stroke onset were analyzed to determine a cutoff time, after which risk exceeds clinical benefit.

Methods: From November 1997 to March 2007, a total of 5369 patients were examined at the authors' stroke unit; 502 from this cohort underwent ICA reconstruction. A subgroup of 49 patients underwent surgical revascularization of acute ICA occlusion within 168 hr at a mean of 42.

Renal artery revascularization after unsuccessful percutaneous therapy: a single centre experience.

Purpose: This retrospective review describes the long time effect of surgical revascularization after unsuccessful early or mid-term failure of percutaneous transluminal renal angioplasty (PTRA).

Methods: From January 1995 to January 2005, 60 out of 696 patients operated due to renal artery occlusive disease (17 fibromuscular dyplasia (FMD): mean age, 33.4 years; 43 atherosclerotic disease (ASD): mean age, 62.

Visceral artery aneurysms--follow-up of 23 patients with 31 aneurysms after surgical or interventional therapy.

Purpose: Visceral artery aneurysms (VAA) are rare forms of vascular pathology, with an incidence of 0.1% to 0.2% in routine autopsies.

Prospective randomized trial of operative vs interventional treatment for renal artery ostial occlusive disease (RAOOD).

Introduction And Objectives: Patients with either renovascular hypertension (RVH) and/or renal insufficiency (RI) due to renal artery ostial occlusive disease (RAOOD) can successfully undergo an open surgical reconstruction procedure (OSRP), but since the publication of Blum et al(1) percutaneous balloon stent angioplasty (PTRA + stent) leaving a small part of the stent within the aorta has become very popular. However, balloon dilatation and stenting does not remove the atherosclerotic plaque, which is often heavily calcified but leads to disruption of the plaque causing myointimal hyperplasia and recurrent stenosis. Therefore, a comparison of the two treatment modalities concerning complications and durability in a prospective randomized design was felt to bring more insight to the discussion.

Spontaneous rupture of collateral venous aneurysm in a patient with agenesis of the inferior vena cava: a case report.

We present a case of rupture of collateral venous vessels in the presence of agenesis of the inferior vena cava in a young woman. The embryologic development, pitfalls in diagnosis, and options for treatment in cases with agenesis of the inferior vena cava are discussed.
