颅内夹层动脉瘤自然病史及其血管内治疗的研究进展

Advances in natural history and endovascular treatment of intracranial artery dissection

颅内夹层动脉瘤(IAD)是一种发生于颅内动脉的特殊类型的动脉瘤,其可以因破裂导致蛛网膜下腔出血、夹层向腔内突出导致缺血性卒中,还可以因管腔的极度扩张产生压迫症状,发生相关事件后有较高的致残率以及致死率.但IAD的自然转归尚不明确,治疗的适应证有待进一步把握.另外,IAD具有不同的临床特征,治疗方式的选择也各有不同.该文通过对于IAD自然病史、新型血管内治疗方式和预后的研究进行综述,对临床上IAD治疗适应证的把握和治疗方式的新选择提供一定参考.

Intracranial artery dissection(IAD)is a special kind of intracranial aneurysm,which could lead to subarachnoid hemorrhage caused by disruption of aneurysms,ischemic stroke owing to artery dissection resulting in stenosis,and mass effect due to excessive expansion of vessel.It is a high risk of morbidity and mortality if those complications are happening.However,the natural history of IAD is unclear,and the indiction of endovascular treatment for IAD is still further to explore.In addition,there is a various option of endovascular treatment for IAD because of its different characteristics.Therefore,this review give an overview of previous studies concerning the natural history,new measures of endovascular treatment,and prognosis for IAD in this review in order to provide some references for indication and treatment options in patients with IAD.
