血管内治疗亚急性及慢性脑动脉闭塞研究进展

摘要

亚急性及慢性脑动脉闭塞是缺血性脑卒中并不常见、但很重要的原因.主要机制是局部血流动力学障碍,理论上改善血流动力学障碍可降低脑卒中发生率,改善预后.目前亚急性及慢性脑动脉闭塞最佳治疗方案尚存争议,介入技术迅速发展使血管内治疗取得了长足进步,但同时也存在一些不足.该文就亚急性及慢性脑动脉闭塞的定义、危害、治疗现状、影像学评估、技术要点、相关并发症等作一综述.%Subacute and chronic cerebrovascular occlusion is an uncommon but an important cause for ischemic stroke.The main pathogenic mechanism is local hemodynamic disorder.Theoretically,the improvement of hemodynamic disorder can reduce the incidence of stroke as well as improve the prognosis.At present,there is still controversy over the optimal therapeutic plan.With the rapid development of interventional techniques,considerable progresses have been made in the endovascular treatment for subacute and chronic cerebrovascular occlusion,although some shortcomings still exist.This article aims to make a comprehensive review about the subacute and chronic cerebrovascular occlusion,focusing on its definition,damage,clinical status of its treatment,imaging evaluation,technical points of endovascular therapy,and procedure-related complications.
