PURPOSE To compare a hybrid magnetic resonance (MR) angiography protocol with selective digital subtraction angiography (DSA) in patients with critical limb ischemia. MATERIALS AND METHODS The study was approved by the institutional review board, and written consent was obtained from all patients. Pretreatment DSA and hybrid MR angiography were performed(More)
BACKGROUND Local and regional anesthesia was used in endovascular aortic aneurysm repair (EVAR) shortly after its introduction, and the feasibility has been documented several times. Nevertheless, locoregional anesthesia has not become accepted on a large scale, probably owing to a traditional surgical attitude preferring general anesthesia. This study(More)
Two cases of percutaneous endoluminal exclusion of a subclavian aneurysm with a Dacron-coated nitinol stent are presented. One subclavian aneurysm followed trauma; the other was due to thoracic outlet stenosis which was caused by a cervical rib. In both patients the aneurysm was excluded successfully. The follow-up periods were 22 and 14 months,(More)
There is still controversy as to which surgical method is the most suitable for repair of abdominal aortic aneurysm with concomitant horseshoe kidney (AAA-HSK). We report three cases of AAA-HSK treated with endovascular aneurysm repair. In one of these patients we sacrificed the accessory renal artery by applying coils before the operation. Renal(More)
OBJECTIVES An ex-vivo model for the experimental evaluation of endoluminal thermal procedures for occlusion of saphenous veins was developed. Radiofrequency obliteration (RFO) and endovenous laser therapy (ELT) were compared using this model. DESIGN Experimental ex-vivo treatment study. MATERIALS AND METHODS The model consists of the subcutaneous foot(More)
Vascular injuries of the extremities account for most instances of vascular trauma (ca. 70%), and they entail a risk of amputation about 10-20%. According to the kind of force that has acted, arterial trauma is classified as direct or indirect. The scale of hemorrhage and peripheral ischemia depend on the nature and severity of the arterial lesion. In(More)
In peripheral arterial disease (PAD) risk of thrombosis is high and systemic haemostatic derangement thought contributory. We investigated platelet and coagulatory activity in patients with PAD and sought to find the best disease indicator. Stagnation point flow adhesion-aggregometry (SPAA) enables real-time quantitative assessment of platelet adhesion and(More)
PURPOSE To review the long-term results of primary stent placement in the distal aorta above the bifurcation. METHODS Fourteen patients (8 men; mean age 62 years, range 46-82) underwent primary stent implantation performed by an interdisciplinary radiosurgical team. In 10 patients, a long-term follow-up examination consisting of patient history, clinical(More)
BACKGROUND Bleeding from suture holes during vascular reconstruction, particularly when polytetrafluoroethylene (PTFE) prostheses are used, is still a problem which can lead to intraoperative delay and increased blood loss. The aim of this prospective, randomised, open, controlled multicentre study was to evaluate whether the use of a new local haemostyptic(More)
PURPOSE To compare anesthesia techniques in high-risk versus low-risk patients treated with endovascular aortic aneurysm repair (EVAR) with respect to outcomes. METHODS From July 1997 to August 2004, 5557 patients were enrolled in the EUROSTAR registry by 164 centers. Low-risk and high-risk patients were each divided into 3 groups according to anesthesia(More)
