OBJECT.: The purpose of this study was to report the authors' experiences in stent-assisted coil embolization (SAC) ruptured wide-necked aneurysms acute period and evaluate incidence risk factors for periprocedural complications.A total 72 patients were recruited between March 2007 June 2012. All met following criteria: 1) presence intracranial saccular aneurysms, 2) patient underwent SAC treatment those within hours rupture. with clinically poor grades or hydrocephalus external ventricular...

Background Flow diverters are used for the treatment of intracranial aneurysms. Surface modification may decrease thrombogenicity flow but details unknown. Optical coherence tomography (OCT) is an intravascular imaging test with high resolution which identifies neointimal growth over stents. We compared development neointima in a diverter and stents without surface swine model. Methods In this study we implanted four devices (two each carotid artery) pigs. The were Pipeline Flex embolization...
Controversy remains about the optimal treatment for blood blister--like aneurysms (BBAs).To evaluate clinical and angiographic outcomes after reconstructive BBA with stent coil.Thirty-four patients (6 men, 28 women; mean age, 47.3 years) ruptured BBAs underwent coil. Posttreatment courses were retrospectively evaluated.Initial treatments ≥ 2 overlapping stents or without coiling (n = 28) single 6). Three rebled on days 9, 11, 15 treatment, resulting in 1 death. Except 3 who died early, 31...
Object The aim of this study is to demonstrate the differences between new Low-profile Visualized Intraluminal Support (LVIS Blue) stenting device and Flow Redirection Endoluminal Device (FRED) using a series bench-top evaluations optical coherence tomography (OCT) images in cadaveric preparation basilar artery. Methods first part evaluation was microscopic documentation metal coverage for LVIS Blue FRED stents. OCT cerebral vessels deployed stents were acquired intravascular imaging. from...
<h3>BACKGROUND AND PURPOSE:</h3> There are only a few reports on the feasibility and safety of stents used in PICA, clinical angiographic follow-up results have not been fully addressed. We report our experiences treating PICA origin or vertebral artery−PICA lesions by using self-expanding as adjuvant rescue therapy with results. <h3>MATERIALS METHODS:</h3> Six patients were treated stent placements from artery to PICA. Two had dissecting aneurysm involving origin, 3 aneurysms, 1 segmental...
This study investigated the effects of granulocyte colony-stimulating factor (G-CSF) on glial scar formation after spinal cord injury (SCI) in rats and compared therapeutic between G-CSF granulocytemacrophage (GM-CSF) to evaluate as a potential substitute for GM-CSF clinical application.Rats were randomly assigned 1 4 groups: sham-operated group (Group 1), an SCI without treatment 2), treated with 3), 4). administered via intraperitoneal injection immediately SCI. The functional recovery,...
To evaluate the rate of neointimal development and thrombus formation surface-modified flow diverters in single antiplatelet therapy (SAPT) using optical coherence tomography (OCT) a porcine model.We divided 10 experimental pigs into two groups. One group (n=6) received dual (DAPT) other (n=4) SAPT. Four stents (two per carotid artery) were implanted both The used Pipeline Flex embolization device (PED Flex), with Shield technology Shield), Solitaire AB stent. All animals underwent weekly...
No evidence is available on the benefits of preventive suboccipital decompressive craniectomy (SDC) for patients with cerebellar infarction. The purpose this matched case-control study was to investigate whether SDC associated good clinical outcomes in infarction and evaluate its predisposing factors.Between March 2007 September 2015, 28 underwent SDC. We performed propensity score matching establish a proper control group among 721 during same period. Group A (n=28) consists those who SDC,...
Antiplatelet therapy, where regimens are tailored based on platelet function testing, has been introduced into neurointerventional surgery. This nationwide registry study evaluated the effect and safety of antiplatelet therapy in stent assisted coiling for unruptured aneurysms compared with conventional using a standard regimen.This enrolled 1686 patients 44 participating centers who received between January 1, 2019 December 31, 2019. The regimen (aspirin clopidogrel) was used all group...
Object Vascular endothelial growth factor (VEGF) has been investigated as a therapy for many disorders and injuries involving ischemia. In this report, we constructed evaluated hypoxia-inducible VEGF expression system treatment spinal cord injury (SCI). Methods The plasmid was using the erythropoietin (Epo) enhancer with Simian virus 40 (SV40) promoter (pEpo-SV-VEGF) or RTP801 (pRTP801-VEGF). of in vitro after transfection into N2A cells. plasmids were then injected rat cords contusion...
The purpose of this study was to report the authors' preliminary experience using self-expanding closed-cell stents deployed in small arteries (< 2 mm diameter) treat intracranial aneurysms.A total 31 patients were studied. All subjects met following criteria: 1) they received an Enterprise stent for treatment a wide-necked aneurysm or dissecting as part stent-salvage procedure; and 2) had parent artery that no atherosclerotic stenosis. Procedure-related complications follow-up sizes...
The operative risk and natural history rupture for the treatment of unruptured intracranial aneurysms (UIAs) should be evaluated. purpose this study was to report our experience with treating UIAs outline clinical factors associated procedure-related major neurological complications.We treated 1158 in 998 patients over last 14 years. All underwent operation performed by a single microvascular surgeon two interventionists at institution. Patient factors, aneurysm outcomes were analyzed...
Transvenous embolization is an effective method for treating dural arteriovenous fistulas (DAVFs) of the transverse-sigmoid sinus (TSS). However, in cases complicated DAVFs, it difficult to preserve patency sinus. The authors describe technical details a new reconstructive technique using transvenous balloon-assisted Onyx as another treatment option patient with extensive and complex DAVF left TSS. A microcatheter compliant balloon catheter were navigated into internal jugular vein placed at...
Stent-assisted coiling of intracranial aneurysms arising from small vessels (≤ 2.0 mm) is a common procedure. However, data regarding its treatment outcomes are scarce. This study evaluated the clinical and radiologic stent-assisted using low-profile stents for parent arteries.From November 2015 to October 2020, sixty-four patients with 66 arteries ≤2.0 mm were treated Low-Profile Visualized Intraluminal Support Junior (LVIS Jr) or Neuroform Atlas stent in single institution. The...
Resection of the anterior clinoid process (ACP) for clipping an internal carotid-posterior communicating artery aneurysm is rarely needed. However, preoperative awareness necessity clinoidectomy essential safe lesions. We investigated predictive value in treating aneurysms.We retrospectively reviewed all patients with a posterior treated past 5 years. Only who underwent both computed tomographic angiography and 4-vessel digital subtraction were included this study. measured several angles...
