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)
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)
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)
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)
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)
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)
OBJECTIVE To determine the efficacy, safety and primary follow-up results of a guidewire looping technique for the treatment of infrapopliteal arteries. MATERIALS AND METHODS From October 2006 to May 2008, an intraluminal angioplasty of the infrapopliteal arteries was attempted in 200 consecutive patients. Altogether, 417 infrapopliteal lesions, with(More)
BACKGROUND To evaluate the efficacy of flow-diverting devices (FDDs) used in the treatment for intracranial aneurysms (IAs), we performed a meta-analysis of published literature on FDDs. METHODS A systematic electronic database search was conducted using MEDLINE, PubMed, Springer, and EBSCO for all accessible articles on FDDs published until December(More)
BACKGROUND We determined the feasibility of, and tissue response to silicone-covered biodegradable magnesium- and plastic-stent insertion into the esophagus in rabbits. METHODS The mechanical compression-recovery characteristics and degradation behaviors of the magnesium stent were investigated in vitro. A total of 45 rabbits were randomly divided into a(More)
OBJECTIVE To prospectively investigate predictors for good restoration of blood flow of below-the-knee (BTK) chronic total occlusions (CTOs) after endovascular therapy in diabetes mellitus (DM) patients. MATERIALS AND METHODS A total of 120 long-segmental (≥ 5 cm) BTK, CTOs in 81 patients who underwent recanalization were included in this study. After(More)
