OBJECTIVE Randomized comparison of endovascular repair (EVAR) with open repair (OR) in patients with a ruptured abdominal aortic aneurysm (RAAA). BACKGROUND Despite advances in operative technique and perioperative management RAAA remains fraught with a high rate of death and complications. Outcome may improve with a minimally invasive surgical technique:(More)
PURPOSE To evaluate anatomical suitability and application rate for endovascular repair of patients with a ruptured abdominal aortic aneurysm (RAAA). METHODS The Amsterdam Acute Aneurysm trial is a multicenter randomised trial comparing open with endovascular treatment in patients with a RAAA (International Standard Randomized Controlled Trial Number(More)
BACKGROUND Spinal cord ischemia is a rare complication after open surgical repair for ruptured abdominal aortic aneurysms (rAAA). The use of emergency endovascular aortic aneurysm repair (eEVAR) is increasing, and paraplegia has been observed in a few patients. The objective of this study was to assess the incidence and pathogenesis of spinal cord ischemia(More)
PURPOSE To assess interobserver and intraobserver agreement on presence of rupture and determining suitability for endovascular repair (EVAR) on CT angiography (CTA) of patients with a suspected ruptured abdominal aortic aneurysm (RAAA). METHODS For the Amsterdam Acute Aneurysm study, a randomised multicenter trial (ISRCTN66212637), we register all(More)
PURPOSE To evaluate stent-graft and aneurysm wall motions during the cardiac cycle using cine magnetic resonance imaging (MRI) to identify mechanisms of long-term failure of endovascular aneurysm repair (EVAR). METHODS Prior to and after EVAR in 7 patients with abdominal aortic aneurysms (AAA), 12 MRI images per cardiac cycle were acquired in transverse,(More)
AIM Complication rates after laparoscopic cholecystectomy vary but are still reported to be up to 17 %. Identifying risk factors for an adverse complication outcome could help to reduce morbidity after laparoscopic cholecystectomy. Our aim was to analyze whether surgeon volume is a vital issue for complication outcome. METHODS All complications-minor,(More)
INTRODUCTION Abdominal aortic aneurysm (AAA) is an age-related disease. In an aging population, the prevalence of AAA is likely to increase. Open AAA repair in patients aged >80 years is often not considered because of their advanced age as such or because of comorbidities. In addition, little is known about the natural history in such patients or survival(More)
BACKGROUND Radiofrequency ablation (RFA) is associated with an excellent outcome in the treatment of great saphenous vein (GSV) incompetence. The use of thermal energy as a treatment source requires the instillation of tumescence anesthesia. Mechanochemical endovenous ablation (MOCA) combines mechanical endothelial damage, using a rotating wire, with the(More)
OBJECTIVES Mechanochemical endovenous ablation is a novel technique for the treatment of great saphenous vein and small saphenous vein incompetence which combines mechanical injury of the endothelium with simultaneous infusion of liquid sclerosant. The main objective of this study was to evaluate early occlusion. METHODS All consecutive patients who were(More)
