Clinical study on endovascular recanalization of symptomatic non ⁃ acute middle cerebral artery occlusion

Objective To assess the feasibility, safety and short⁃term outcomes of angioplasty and stenting for patients with symptomatic non⁃acute middle cerebral artery occlusion (SNAMCAO). Methods Eight SNAMCAO patients who failed in medical treatment and underwent endovascular recanalization, were collected from January to December 2019. The success rate, perioperative complications, prognosis and stent restenosis were summarized. Results In 8 cases, 7 cases succeeded and one case failed. Four cases occurred perioperative complications, including symptomatic intracranial hemorrhage (2 cases), transient ischemic attact (1 case) and stent thrombosis (1 case). Seven to 13d after operation the modifical Rankin Scale(mRS)0-2 score were seen in 6 cases, 3 in one case and 4 in one case. Four months after operation one case occurred restenosis in the stent. Conclusions For patients with SNAMCAO, if medical treatment is not effective, endovascular recanalization can be considered, but the recanalization technique is complicated and the incidence of complications is still high. Therefore, the safety and necessity of endovascular recanalization need to be strictly evaluated. DOI：10.3969/j.issn.1672⁃6731.2020.06.008
