Abstract:
【Objective】To observe the hemorrheological changes in lacunar cerebral infarction(LCI) patients with arteriopathy of middle and small arteries.【Methods】The hemorrheological changes of cerebral arteries in 85 LCI patients without arteriopathy of large artery confirmed by cervical vessels color ultrasonography and magnetic resonance image(MRI)were observed by transcranial Doppler ultrasonography(TCD).The correlation of the hemorrheological changes with age and blood pressure(BP) of arteries was investigated.The above indexes were compared with those in 25 healthy volunteers confirmed by encephalography in the same age group.【Results】The mean blood flow rates of cerebral middle,anterior and posterior artery in LCI patients were(62.09?16.90)cm?s~(-1),(50.42?13.11)(cm?s~(-1),)and(32.33?7.55)cm?s~(-1) respectively,lower than(69.65?19.20)cm?s~(-1),(57.75?16.75)cm?s~(-1),and(38.75?8.81)cm?s~(1) respectively in the healthy volunteers(P0.05).【Conclusion】The arteriopathy of small artery in LCI patients can cause the mild decrease of blood flow rate and the increase of pulsating index.There exists a correlation of pulsating index with age and arterial blood pressure.
