Clinical study on 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 (SNMCAO). Methods Eight SNMCAO patients who failed in medical treatment and under - went surgical 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 adn 1 case failed. Four cases occurred perioperative complications, including symptomatic intracranial hemorrhage (2 cases), fransient cerebral ischemic attact (1 case) and stent thrombosis (1 case). Seven to thirty days after operation the modifical Rankin Scale (mRS) 0-2 score were seen in 6 cases, 3 in one case and 4 in one. Four months after operation one case occurred restenosis in the stent. Conclusions For patients with SNMCAO, 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. [ABSTRACT FROM AUTHOR]
