Background Endovascular therapy has been shown to be effective in patients with acute cerebral large‐vessel occlusion, but real‐world efficacies are unknown. Methods and Results We conducted a prospective registry at 46 centers between October 2014 January 2017. Eligible were those who aged 20 years or older, hospitalized within 24 hours of the onset. enrolled both consecutive treated without endovascular therapy. included thrombectomy, balloon angioplasty, stenting, local fibrinolysis,...
Because of its high complication rate, the endovascular treatment (EVT) anterior communicating artery (ACoA) aneurysms less than 3 mm in maximum diameter remains controversial. We evaluated EVT tiny ruptured ACoA with Guglielmi detachable coils (GDCs).We treated 19 a <or=3 GDCs. The pretreatment Hunt and Hess score was grade 1 four patients, 2 six, 4 three. patients were clinically assessed before after multiple angiographic follow-up studies.All EVTs successful; there no aneurysm...
Our aim was to assess the feasibility of carotid artery stent placement (CAS) for calcified lesions.Using embolic protection devices (EPDs), we performed 51 CAS procedures in 43 patients with severe stenosis accompanied by plaque calcification. Before intervention, all lesions were subjected multidetector-row CT. The arc circumferential calcification measured on axial source images at site maximal luminal stenosis, and total volume determined. angiographic outcome immediately after CAS,...
A 38-year-old man presented with a dissecting aneurysm of the left proximal posterior inferior cerebellar artery (PICA) manifesting as Wallenberg’s syndrome. The patient was treated by endovascular occlusion and parent artery. Immediately after treatment, PICA territory supplied collateral circulation via ipsilateral anterior Seven days later, endogenous revascularization distal had occurred from meningeal (PMA). This unusual thought to occur through pre-existing anastomotic channel between...
This study retrospectively reviewed 227 patients with ruptured solitary cerebral aneurysm who underwent endovascular embolization detachable coils between March 1997 and 2006 to establish the incidence of rebleeding after treatment for identify risk factors. The site size aneurysm, interval rebleeding, outcome were investigated in six (2.6%) rebled treatment. Four had large or giant aneurysms located on internal carotid artery at origin posterior communicating artery. was less than 1 year...
A 17-year-old woman presented with a rare aneurysm at the junction of persistent primitive trigeminal artery (PPTA) and internal carotid (ICA) manifesting as left abducens nerve paresis. The ICA were both successfully occluded coils. balloon occlusion test used HyperForm microcatheter to seal PPTA ICA, which is very important determine optimal treatment strategy for aneurysm.
After coil embolization for an aneurysm, edema surrounding the aneurysm revealed by magnetic resonance imaging (MRI) is rarely seen and usually associated with neurological symptoms. Perianeurysmal was found postoperative MRI in three out of 182 patients cerebral which treated Guglielmi Detachable Coil (GDC), symptoms developed simultaneously. In cases where improved conservative medical treatment, a temporary increase volume due to thrombus formation, may result edema. were not alleviated...
A 62-year-old man experienced transient episodes of vertigo associated with left upper extremity weakness. Cerebral angiography showed 75% right internal carotid artery (ICA) stenosis and divergence a persistent primitive hypoglossal (PPHA) distal to the stenosis. The area was at high position he had past medical history congestive heart failure, which contraindicated endarterectomy (CEA). Therefore, stenting (CAS) performed single balloon protection. stenotic restored discharged without...
Changes in the cerebral blood flow (CBF) are important for planning postoperative care patients treated by carotid artery stenting (CAS). The relationship between intraprocedural changes angiographic circulation time (CCT) and perioperative CBF were retrospectively studied 49 CAS procedures performed 46 with stenosis. CCT, defined as interval timing of maximal opacification at terminal portion internal cortical vein, was determined referring to time-density curves data obtained from routine...
The rates of hemodynamic depression (HD) and thromboembolism were compared in 95 carotid artery stenting (CAS) procedures performed 87 patients with severe stenosis using self-expandable braided Elgiloy stents (Wallstent) 52 slotted-tube Nitinol (Precise) 43 procedures. blood pressure, pulse rate, neurological signs recorded at short intervals during after CAS. All underwent diffusion-weighted magnetic resonance imaging within 5 days the procedure. incidences hypotension, bradycardia, both...
An 87-year-old man presented with extracranial vertebral artery (VA) occlusion and progressive vertebrobasilar ischemia despite maximal medical management. Cerebral angiography showed left proximal VA occlusion, termination of the right at ipsilateral posterior inferior cerebellar artery, hypoplastic bilateral communicating arteries. Although stump ostium was not visualized, distal patent reconstituted via muscular branches from subclavian (SCA). Endovascular angioplasty a stent for...
Stent-assisted coil embolization (SACE) is used to address wide-necked or complex aneurysms. However, periprocedural and/or late in-stent thrombosis (IST) elicit neurological events. We investigated the incidence and timed development of acute IST during SACE with braided- laser-cut stents in a retrospective study. Between May 2013 April 2018, we evaluated 11 ISTs that occurred course 185 procedures (self-expandable stent, n = 128; braided 57). The onset was measured from time stent...
We investigated the safety and efficacy of consciousness sedation with dexmedetomidine (DEX) during endovascular treatment patients acute cerebral infarction. Between April 2014 November 2016, 38 stroke underwent thrombectomy (EVT) under local anesthesia DEX sedation. The continuous intravenous administration low-dose (0.3-0.4 μg/kg/h) was started before entering operating room. Patients not completely immobilized received an iv bolus pentazocine (PTZ) and/or (0.5-0.6 μg/kg/h). EVT performed...
