Vascular ultrasound assessment of internal carotid artery dissection and vertebral artery dissection and the difference analysis of lumen recanalization / 中国脑血管病杂志

ABSTRACT

Objectives To diagnose and test cervical artery dissection (CAD) during the follow-up by color Doppler flow imaging (CDFI) and to analyze and compare the differences of internal carotid artery dissection ( ICAD) and stenosis degree of vertebral artery dissection ( VAD) , and lumen recanalization. Methods From January 2016 to December 2018 , a total of 136 consecutive patients (160 dissecting vessels) with CAD of intramural hematoma type diagnosed by CDFI and confirmed by high-resolution MRI and/or CT angiography in Xuanwu Hospital .Capital Medical University were enrolled retrospectively. They were divided into ICAD group (n =66, with 75 ICADs) and VAD group (n =70,with 85 VADs).The gender, age,risk factors,cerebral ischemic symptoms, and CDFI manifestations were compared in the patients between the two groups. They were followed up at 3,6, and 12 months after onset. The patients with CAD were reexamined, and the difference of recanalization rate between the two groups was compared. Results There was a statistically significant difference in the mean age and proportion of hypertension between the ICAD group and the VAD group (both P 0. 05); there was significant difference in the degree of vascular stenosis (P 0. 05) between the VAG group and the ICAD group. Conclusions ICAD was different from VAD in the degree of lumen stenosis and the rate of lumen recanalization at different follow-up time. CDFI had good test and follow-up re-examination values for CAD.
