OBJECT Placement of covered stents has emerged as a promising therapeutic option for cerebrovascular diseases. However, the medium- and long-term efficacy and safety of covered stents in the treatment of these diseases remain unclear. The purpose of this study was to evaluate the medium-term clinical and angiographic outcomes of covered stent placement for(More)
PURPOSE The current study evaluates the feasibility and safety of coil embolisation of the anterior communicating artery (ACoA) for the treatment of complicated anterior communicating arterial aneurysms (ACoAAs). METHODS AND MATERIALS Five patients presented with a subarachnoid haemorrhage caused by a ruptured ACoAA. The ACoAA morphologies were well(More)
PURPOSE To assess the feasibility and efficacy of subintimal angioplasty (SA) in the treatment of below-the-ankle arterial occlusion in diabetic patients with chronic critical limb ischemia (CLI). METHODS SA was applied in 37 diabetic patients (24 men; mean age 70.9+/-8.5 years, range 52-88) with chronic CLI and occlusive disease of the dorsalis pedis(More)
PURPOSE To assess the technical feasibility and efficacy of transdorsal-to-plantar (TDP) or transplantar-to-dorsal (TPD) intraluminal re-entry following unsuccessful subintimal angioplasty for arterial occlusion below the ankle. METHODS TDP or TPD retrograde intraluminal re-entry angioplasty was attempted in 8 limbs of 8 diabetic patients (5 men; mean age(More)
BACKGROUND Retrievable temporary stent placement has recently been suggested as a potential treatment for benign esophageal stricture. OBJECTIVE To assess the efficacy of a newly designed cardia stent for the treatment of benign cardia stricture in a canine model compared with groups that received pneumatic dilation or standard esophageal stent insertion.(More)
BACKGROUND The use of short balloons in the treatment of infrapopliteal arterial occlusive disease in diabetic patients often has a poor clinical outcome. PURPOSE To retrospectively evaluate the safety and efficacy of a long over-the-wire (OTW) balloon as a primary percutaneous transluminal angioplasty (PTA) treatment for diabetic infrapopliteal severe(More)
PURPOSE To compare the feasibility and efficacy of recanalizing below-the-knee (BTK) chronic total occlusions (CTOs) between patients with good or poor distal runoff based on magnetic resonance angiography (MRA) scans. METHODS Two hundred long-segment BTK CTOs in 171 limbs of 113 diabetic patients (58 men; mean age 69.8±1.9 years) were divided into good(More)
OBJECT The development and preclinical assessment of new endovascular devices necessitate readily available and reproducible animal models. The purpose of this study was to develop an in vivo carotid siphon model for testing the properties of covered stents specially designed for the intracranial vasculature. METHODS Six carotid siphon-shaped devices were(More)
PURPOSE To compare the use of the Willis stent-graft versus coil embolization for complicated aneurysms in the cisternal segment of the internal carotid artery (ICA). METHODS Thirty-four patients (19 women; mean age 46.7+/-16.8 years, range 3-79) with 36 complicated aneurysms were treated either by Willis covered stents (n = 19) or by coil embolization (n(More)
BACKGROUND AND PURPOSE The aim of this study was to evaluate the anatomical changes and investigate the prevalence in intracranial aneurysm with fenestrations using magnetic resonance angiography (MRA). MATERIALS AND METHODS Between June 2008 and October 2010, 4652 patients (aged 23-73 years) with suspected intracranial aneurysm or other cerebrovascular(More)
