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)
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)
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)
BACKGROUND This study evaluated the ability of endovascular optical coherence tomography (eOCT) to detect qualitative tissue alteration and quantitative changes of vein wall thickness and vein lumen diameter comparing endovenous radiofrequency ablation (RFA) and endovenous laser therapy (ELT) in an established ex vivo model. METHODS Endoluminal eOCT was(More)
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)
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)
BACKGROUND In peripheral arterial disease (PAD) atherosclerosis is disseminated and thrombosis risk is high. We have not only shown the platelets of PAD patients to by hyperreactive and aspirin resistant, but have recently verified them to be hypersensitive to heparin as well. In the present study we have begun to clarify the mechanisms underlying these(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)
The release of the neuronal protein S-100B into the circulation has been suggested as an early indication of cellular brain damage. The objective of this prospective pilot study was to determine S-100B serum levels in patients undergoing cross-clamping during carotid endarterectomy (CEA) and to correlate the results with the monitoring of somatosensory(More)
