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 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 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)
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 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)
PURPOSE The purpose of this article is to evaluate the efficacy and safety of covered stent implantation for large intracranial aneurysms treated with stent-assisted coiling. MATERIALS AND METHODS Seven patients with a cerebral aneurysm were selected for this study. The aneurysms were located at the cavernous segment of the internal carotid artery in(More)
OBJECTIVES To evaluate the efficacy of percutaneous aspiration thrombectomy (PAT) for infrainguinal arterial thromboembolism in patients undergoing endovascular recanalization (EVR) and to investigate the predictors for thromboembolic complications. MATERIALS AND METHODS In total, 23 patients (23 limbs) who underwent PAT for thromboembolism (PAT group,(More)
