动脉硬化患者与健康人椎动脉血流量对比研究

Comparative study of vertebral arterial blood flow between arteriosclerosis patients and healthy people

目的 运用彩色多普勒超声（CDUS）对健康人及椎动脉硬化患者椎动脉血流量进行对比研究,探讨动脉硬化对椎动脉血流量的影响.方法 选取进行椎动脉检查的患者285例,根据有无椎动脉硬化分为正常组（135例）及动脉硬化组（150例）.运用CDUS技术测量椎动脉平均流速（TAMV）及椎动脉内径（D）,计算单侧椎动脉血流量及总血流量.结果 动脉硬化组椎动脉TAMV及总血流量均低于正常组（P＜0.05）,2组椎动脉D左侧均高于右侧,差异具有统计学意义（P＜0.05）.结论 动脉硬化可降低椎动脉TAMV及总血流量,且椎动脉D以左侧优势为主.

Objective To conduct comparative study of vertebral artery blood flow of arteriosclerosis patients and healthy people using color Doppler ultrasound （CDUS）, and to discuss the effect of arteriosclerosis on vertebral arterial blood flow. Methods Two hundred and eighty-five cases of vertebral artery test were collected and divided in to normal group of one hundred and thirty-five cases and vertebral artery sclerosis group of one hundred and fifty eases according to the presence of vertebral artery sclerosis. Time averaged maximum velocity （TAMV） and vertebral artery diameter（D） of vertebral artery were measured using CDUS technique. Unilateral vertebral artery blood flow and total blood flow were calculated. Results The vertebral artery TAMV and total blood flow of arteriosclerosis group was both lower than that of normal group （P〈0.05）. Left side vertebral artery diameters of the two groups were higher than that of the right side. Conclusions Arteriosclerosis can reduce vertebral artery TAMV and blood flow. The inner diameter of the left side vertebral artery dominates the artery blood flow.
