Covered stent placement has emerged as a promising therapeutic option for intracranial vascular lesions. However, in-stent stenosis and occlusion continue to be important concerns with the use of a covered stent, which is more thrombogenic than other types of stents. The purpose of this study was to determine predictors of in-stent stenosis and occlusion(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)
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)
BACKGROUND AND AIM To retrospectively analyze and compare the clinical efficacy of temporary stent insertion with pneumatic dilation of the same diameter in the treatment of achalasia based on a long-term follow up. METHODS A total of 101 treated achalasia patients were divided into a pneumatic dilation group (Group A, n = 38) and a temporary stent(More)
BACKGROUND/AIMS To investigate whether temporary placement of a paclitaxel or rapamycin eluting stent is more effective to reduce stenting induced inflammatory reaction and scaring than a bared stent in benign cardia stricture models. MATERIALS AND METHODS Eighty dog models of stricture were randomly divided into a control group (CG, n=20, no stent(More)
OBJECTIVES 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). METHODS This retrospective analysis comprised 63 patients with diabetes (98 limbs) who underwent ER for(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)
BACKGROUND Trans-venous embolisation has been accepted as the preferred treatment for dural carotid-cavernous fistulae (DCCF). However, such an approach is not always feasible. In this circumstance, trans-arterial embolisation with low concentration n-butyl-cyanoacrylate glue (NBCA) may be a feasible alternative. We report our results and experience of this(More)
OBJECTIVE To review the literature on flow-diverting device (FDD) treatments for intracranial aneurysms (IAs) and to compare the safety and efficacy of FDDs with coil embolization treatment (CET) for IAs using a meta-analysis of published studies. METHODS A systematic electronic search was conducted of PubMed, Springer Link, EBSCO, and the Cochrane(More)
OBJECTIVE 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). METHODS Forty-five aneurysms in 41 patients receiving covered stents in three centres were followed. Outcome measures included(More)
