Background Coil embolization of intracranial aneurysms is being increasingly used; however, thromboembolic events have become a major periprocedural complication. Objective To determine the safety and efficacy prophylactic tirofiban in patients with ruptured aneurysms. Methods Tirofiban was administered as an intravenous bolus (8.0 μg/kg over 3 min) followed by maintenance infusion (0.10 μg/kg/min) before stent deployment or after completion single coiling. Dual oral antiplatelet therapy...
Purpose To investigate the safety and outcome of intracranial stenting for atherosclerotic stenosis (IAS). Materials Methods Between July 2007 April 2013, 433 consecutive patients with IAS >70% underwent Wingspan stenting, data were prospectively analyzed. Results Intracranial was successful in 429 (99.1%), mean rate improved from prestenting (82.3± 7.6)% to poststenting (16.6 ± 6.6)%. During 30-day perioperative period, 29 (6.7%) developed stroke. The total stroke significantly (P <0.01)...
Background Thromboembolic complications after stenting of intracranial aneurysms may be affected by antiplatelet administration. Aims This retrospective study aimed to assess the safety intravenous tirofiban versus loading dose oral clopidogrel for preventing thromboembolism in stent-assisted coiling aneurysms. Methods From January 2006 December 2013, 281 patients with cerebral were treated stent-coiling using two strategies comparison: initial strategy (a ≥300 mg followed dual antiplatelet,...
To investigate the safety and long-term effect of using Wingspan stent for severe symptomatic atherosclerotic basilar artery stenosis (≥70%).Between July 2007 April 2013, we had 91 consecutive patients (age range 41-82 years old) with (70-99%) who underwent stenting at our center. All stenosis-related temporary ischemic attack or strokes. We analyzed demographic data, pre- post-procedural cerebral angiography, technical success rate, peri-procedural complications, clinical imaging...
To evaluate feasibility and safety of transvenous embolization for brain arteriovenous malformations (AVMs). Between November 2016 August 2017, a endovascular protocol was implemented at the Henan Provincial People's Hospital consecutive patients with ruptured AVMs. Therapeutic decision making based on Spetzler-Martin grade, AVM location, pattern venous drainage, angioarchitecture. Transvenous combined transarterial support. Complete angiographic obliteration nidus objective treatment. Among...
Abstract From May 2003 to 2010, a total of 9 patients with severe hemobilia after percutaneous transhepatic cholangial drainage (PTCD) were diagnosed using superselective angiography and cholangiography, then treated interventional procedures. Two hepatic arterio-biliary fistula underwent proximal distal arterial embolization the responsible vessel. Six pseudoaneurysm had occlusion embolization. Another patient biliary-portal vein received biliary fully covered stent placement. The effects...
The efficacy and safety of transvenous embolization for brain arteriovenous malformations remains unclear, given the very limited number cases reported. This prospective study was performed to assess this technique in ruptured AVMs. Twenty-one consecutive patients with AVMs who underwent were prospectively followed between November 2016 2018. Spetzler-Martin grade I 3 (14.3%), II four (19.0%), III eleven (52.4%), IV three (14.3%). complete AVM occlusion rate calculated from 6-month follow-up...
Drug-eluting coronary stents have been used for patients with vertebral artery stenosis to prevent the occurrence of in-stent restenosis which affects therapeutic efficacy angioplasty and stenting.However, results are inconsistent. 1A new cerebrovascular sirolimus-eluting stent system (Maurora, Alain Biotechnology Co. Ltd., Beijing, China), 2 different from Apollo systems (Apollo, MicroPort Scientific Corp., Shanghai, China) made 316L stainless steel, 3 adopts L605 cobalt-chromium alloy that...
The aim of this study was to evaluate the safety and efficacy multimodal reperfusion therapy (MMRT) for tandem internal carotid artery middle cerebral arterial (TIM) occlusions. Cases TIM occlusion were collected retrospectively reviewed. analyzed objects included etiology, sites occlusion, collateral flow, location size infarcts. Combined with mechanical recanalization techniques its complications, National Institute Health Stroke Scale (NIHSS) score imaging data that derived pre-...
To investigate the perioperative complications of transvenous embolization ruptured intracranial arteriovenous malformations.A total 27 patients with malformations underwent were enrolled from November 2016 to May 2020 in our prospective database. Perioperative and angiographic characteristics analyzed retrospectively.Complete disappearance nidus occured 22 (88%) 25 technically feasible AVMs immediately after embolization. Two cases partially treated by transarterial due failure...
The objective of this study was to evaluate the feasibility and outcomes transvenous endovascular embolization (TVE) for superficial intracranial arteriovenous malformations (AVMs).After collecting clinical imaging data, a prospective series 11 patients presenting with AVMs were treated by using approach between November 2016 October 2018.Ten (90.9%) had ruptured before TVE. mean nidus size 3.27 ± 1.47 cm, median Spetzler-Martin grade II. rate immediate angiographic occlusion 90.9% (10/11)....
Transarterial and transvenous embolization methods are considered effective safe approaches for the treatment of cavernous sinus dural arteriovenous fistula (CSDAVF). Here., we report angioarchitectural features clinical outcomes CSDAVF in patients treated with either inferior arterial approach (IAA) or petrosal (IPSA).The data 32 at our institution from May 2008 to 2014 were retrospectively analyzed. All underwent routine diagnostic digital subtraction angiography (DSA) before surgery....
Abstract Introduction Brain arteriovenous malformation (bAVM) might have a higher risk of rupture after partial embolization, and previous studies shown that some metrics vascular stability are related to bAVM risk. Objective To analyze in patients embolization. Methods Twenty‐four who underwent embolization were classified into the short‐term, medium‐term, long‐term groups, according time interval between surgery. The control group consisted 9 surgery alone. Hemodynamic changes measured by...
Intracranial arteriovenous malformations (AVMs) are congenital anomalies of the blood vessels. Three traditional methods AVMs therapy have evolved to treat AVMs: microsurgery, stereotactic radiosurgery and transarterial embolization. The principle treatment involves eliminating nidus, which is source hemorrhage, without compromising normal arterial drainage venous brain. More recently, transvenous approach in treating was popularized by successful models for dural fistulas peripheral...
<h3>Purpose</h3> Due to limited data of 69 cases reported up now, the transvenous embolization for brain AVMs is still considered an unproven salvage therapy. Our aim was explore safety and curability treatment. <h3>Materials methods</h3> Between November 2016 2018, 21 consecutive patients with ruptured who underwent were prospectively followed. The Spetzler-Martin grade was: I II (33.3%, n = 7), III (52.4%, 11), IV V (14.3%, 3). Safety evaluated by observing procedure-related complications...
