Abstract:
Objective To explore the distribution characteristics of intra/extracranial large-artery disturbance in patients with ischemic stroke (IS)/transient ischemic attack (TIA).Methods The medical history information of 169 IS/TIA patients was recorded.The results of laboratory examination,electrocardiogram,echocardiography,abdominal ultrasound and chest radiography were analyzed.At the same time,the intra/extra-cranial large arteries were examined to analyze the degree,distribution and pattern of their disturbance.Results Among them,there were intra/extra-cranial large-arterial stenosis (n =112,66.3％) and small-arterial disturbance (n =57,33.7％).Multiple vascular disturbance pattern was more common in patients with intra/extra-cranial large-arterial stenosis (n =71,63.4％).The incidence of intracranial large-arterial stenosis was significantly higher than that of extracranial large-arterial stenosis (53.8％ vs.35.5％,P ＜ 0.05).And middle cerebral artery was the most commonly affected artery,36 of those were culprit vessels accounting for 73.5％ (36/49).Conclusions The IS/TIA patients have a high incidence of intra/extra-cranial large-arterial stenosis.Multiple vascular disturbance is a more common pattern.The incidence of intracranial large-arterial stenosis is greater than that of extracranial and middle cerebral artery is the most common affected artery.
