“…Third, patients with high anatomic risks for PTAS have been excluded from the trial. 17 This study includes only M1 stenosis. Basilar artery, which carries a higher procedural risk for stenting according to some authors, are included in SAMMPRIS trial but not in this study.…”

“…which could be avoided by proper patient screening. 17 We hypothesized intracranial angioplasty and stenting plus medical therapy was better than medical therapy alone in patients with symptomatic severe MCA stenosis who are at low risk for endovascular therapy. We started a prospective, randomized, controlled, single-center clinical trial to test this hypothesis in 2007 in Xuanwu Hospital.…”

Another study demonstrated anatomic features related to high complication rate of intracranial angioplasty and stenting, Background and Purpose-To investigate the efficacy and safety of percutaneous transluminal angioplasty and stenting (PTAS) for symptomatic middle cerebral artery stenosis compared with standard medical treatment in a low-risk Chinese population. Methods-A prospective, randomized, controlled, single-center clinical trial was conducted comparing PTAS with medical treatment for symptomatic middle cerebral artery stenosis (≥70%). Patients were enrolled according to 1:1 enroll ratio (PTAS: medical). The PTAS group received stenting or balloon angioplasty, whereas the medical treatment group received standard medical treatment (aspirin 100 mg plus clopidogrel 75 mg/d), and all the patients were under strict control of the risk factors. The end point events were any kind of ipsilateral stroke or transient ischemic attack, or death from any origin during 1-year follow-up. Results-The enrollment was stopped after 70 patients were enrolled from August 2007 to December 2010, with a 30-day rate of end point events of 8.3% versus 5.9% (P=0.69) for PTAS and medical group, respectively, and 1-year rate of end point events of 19.4% versus 17.6% (P=0.85), respectively. There was no significant difference in baseline characteristics between the 2 groups. The mean follow-up time, which was ongoing, was 9.9 ± 3.9 and 9.7 ± 4.4 months, respectively. Among the risk factors, hypertension was the independent related to the outcome (P=0.015). Conclusions-This study showed that endovascular treatment is as safe but not better than medical treatment for symptomatic middle cerebral artery stenosis in a low-risk Chinese population. History of hypertension increases the risk of recurrent ischemic events.

“…In types B and C, however, the risk was high, and effective dilatation could not be achieved in many patients. 6) To overcome such problems with the balloon catheter, metal stents were introduced with a high expectation, and their effectiveness and favorable therapeutic results have been reported. 7,8) We used coronary stenosis in majority of cases.…”

“…A revascularização endovascular pode beneficiar pacientes com comprometimento hemodinâmico devido a atero s c l e rose intracraniana 2 7 . A indicação da angioplastia com ou sem stent é feita com o insucesso do tratamento clínico e tem sido empregada em combinação com trombólise intra-arterial (IA), pro p i c i a ndo restauração do diâmetro vascular e reduzindo as complicações locais, entretanto, os resultados variam conforme a complexidade das lesões 28 . São exemplos desta situação a refratariedade da oclusão ao trombolítico, a reoclusão da artéria submetida à trombólise, presença de estenose crítica na origem da artéria vertebral após à lise de um tro m b o distal à estenose 2 9 .…”

. O fórum de "Opinião Nacional" foi realizado em São Paulo-SP, no dia 1º de julho de 2004. Os temas de trabalho foram divididos para análise inicial por grupos de 5 a 6 neuro l o g i s t a s . Os coordenadores do presente tema foram os Drs. Cesar N. Raffin e Jefferson Gomes Fernandes. Um esboço de texto foi proposto para análise em plenário em leitura pública. Comentários, críticas e sugestões de mudanças foram amplamente debatidos por este plenário e incorporados ao texto final, redigido pelo grupo responsável pelo tema. RESUMO -Este artigo apresenta as conclusões sobre revascularização clínica e intervencionista no acidente vascular cerebral isquêmico agudo, um dos temas discutidos na reunião "Opinião Nacional sobre o Tr a t a m e n t o do AVC". Tratou-se de reunião promovida e coordenada pela Sociedade Brasileira de Doenças Cere b ro v a s c u l a re s , com neurologistas especializados em doenças cere b ro v a s c u l a res, que analisaram e discutiram as evidências e experiências atuais sobre o uso de trombólise e técnicas intervencionistas em pacientes com acidente vascular c e rebral isquêmico agudo.PALAVRAS-CHAVE: acidente vascular cerebral agudo, trombólise, opinião nacional. Clinical and interventional revascularization in the acute ischemic stroke: national opinionABSTRACT -The Brazilian Stroke Society constituted a committee composed by specialists from diff e rent are a s of Brazil that emitted a viewpoint called "National Opinion" , considering the interventional pro c e d u res and t h rombolysis in the treatment of the acute ischemic stroke.
