Endovascular treatment for subacute and chronic cerebrovascular occlusion: recent progress in research / 介入放射学杂志

ABSTRACT

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.
