OBJECTIVE in diabetic patients with critical limb ischaemia (CLI) an inferior success rate following infrainguinal bypass surgery is quite often suggested. The aim of this retrospective analysis was, therefore, to evaluate the graft patency and, particularly, the clinical outcome at 1 year in diabetic compared with non-diabetic patients. MATERIAL AND(More)
Three-dimensional gadolinium MR angiography (3D-Gd-MRA) accurately visualizes the renal arteries with almost no degradation from inplane saturation or motion artifacts. The diagnostic accuracy for detecting and grading of renal artery stenosis, as well as the assessment of other vascular pathology, approaches that of conventional x-ray angiography. For the(More)
BACKGROUND This study was a retrospective review of 19 patients with popliteal artery entrapment syndrome (PAES) treated in a 20-year interval. METHODS The Heidelberg classification of PAES was used, which differentiates three categories of entrapment: in type I the popliteal artery has an atypical course, in type II the muscular insertion is atypical,(More)
OBJECTIVE Evaluation of the therapeutical efficacy of emergency carotid endarterectomy (CEA) in neurologically unstable patients. PATIENTS AND METHODS Three groups of a consecutive series of 71 emergency CEAs performed from 1980 to July 1998 were classified: (1) acute onset of severe stroke (n = 16), (2) progressive stroke/stroke in evolution (n = 34),(More)
Renal artery stenosis with resultant renovascular hypertension has attracted clinical attention because the disease is potentially curable and because numerous diagnostic and therapeutic modalities compete for clinical acceptance. An exercise-mediated disturbance of renal hippurate transport was recently described, and has been implicated as having a role(More)
Between 1980 and 1990, 21 patients with 26 renal artery aneurysms (0.4-16.5 cm in diameter) were diagnosed and treated at the Surgical Center, University of Heidelberg. Surgical reconstructive methods were applied to treat extrarenal and interventional embolization to treat intrarenal aneurysms. The most effective diagnostic method is selective(More)
PURPOSE To evaluate the anatomic morphology of abdominal aortic aneurysms (AAAs) and compose a classification system to facilitate patient selection for endovascular graft (EVG) repair. METHODS Data on 242 consecutive AAA patients evaluated on a nonemergent basis in a 3.5-year period to July 1996 were prospectively entered into a registry. Patients were(More)
OBJECTIVE To report the collaborative data of 3 major European Vascular Units using the 'visceral hybrid' procedure for thoraco-abdominal aortic aneurysms and dissections. METHODS A consecutive series of 107 urgent and elective high-risk patients were included in a prospectively collected database. RESULTS All stents involved the entire thoracic and(More)
The clinical course of 23 patients with 28 renal artery aneurysms (RAAs) is reported. The RAAs were recorded over a period of 10 years. Thirty-five per cent of the RAAs (eight of 23 patients) were detected during the investigation of hypertension, whereas 26% (six of 23 patients) were discovered incidentally while imaging atherosclerotic arterial disease in(More)
This clinical trial aimed to prospectively investigate the morphological structure of infrarenal abdominal aortic aneurysms (AAA) to establish a valid dataset in the preoperative assessment supporting either the conventional or endovascular (TPEG) surgical approach. Regarding both the general feasibility testing and safe TPEG placing, all the anatomic AAA(More)
