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)
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)
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)
Our aim was to assess the reliability of detecting distal runoff vessels using contrast-enhanced MR angiography (CE-MRA) that were occult on digital subtraction angiography (DSA) for predicting the outcome of endovascular recanalization (ER). This retrospective analysis comprised 63 patients with diabetes (98 limbs) who underwent ER for infrapopliteal(More)
PURPOSE To evaluate the efficacy of the Willis covered stent in the treatment of traumatic pseudoaneurysms of the internal carotid artery (ICA). MATERIALS Thirty-eight patients with traumatic head and neck injury underwent angiography. We evaluated 14 delayed pseudoaneurysms in 13 patients who underwent angiography after treatment with the Willis covered(More)
We investigated immediate/late endoleaks and long-term patency following stent-graft placement for treatment of intracranial aneurysms located within the distal internal carotid artery (ICA) or vertebral artery (VA). Forty-five aneurysms in 41 patients receiving covered stents in three centres were followed. Outcome measures included aneurysm occlusion(More)
BACKGROUND Endovascular embolization for very small cerebral aneurysms (VSCAs) is still controversial. We report our experience with endovascular coil embolization for these lesions and assess the feasibility and effectiveness. METHODS We conducted a review of our experience with endovascular treatment of a series of 19 patients with 20 VSCAs, located at(More)
