锁骨下动脉盗血的椎动脉和桡动脉血流分析

Analysis in the blood flow of vertebral and radial artery in subclavian steal

目的 分析比较 19例锁骨下动脉盗血患者锁骨下动脉、椎动脉和桡动脉间血流速关系。方法 用经颅多普勒超声诊断仪检测其血流速 ,并进行比较。结果 患侧反向椎动脉血流与桡动脉血流有显著相关性 (P<0 .0 5 ) ;锁骨下动脉与反向椎动脉及桡动脉血流速间无相关性 (P>0 .0 5 )。结论 锁骨下动脉盗血患者桡动脉血流速取决于侧支循环建立的完善与否。当侧支代偿好时桡动脉血流可完全正常 ;

Objective To analyze the relationship of the blood flow among the subclavian,vertebral and radial artery in 19 patients with subclavian steal syndrom (SSS).Methods To test blood flow velocity with TCD and analyze in statistics.Results It is obviously relation between radialis artery and reverse blood flow of vertebral artery ( P <0.05) in SSS.It is not correlative beween subclavian artery and reverse blood flow of vertebral and radialis flow.Conclusions The radialis velocity is determined by collateral circulation.When the collateral circulation is good,the radialis velocity may be normal,Whereas,the risk of brain ischemia would be increase.
