摘要: Objective: To discuss the changes of carotid atherosclerosis and intracranial arterial hemodinamics in patients with essential hypertension. Methods: One hundred and seven patients with essential hypertension were divided into two groups: The simple hypertension group (n = 63) and hypertension complicated by cardio-cerebrovascular diseases group (n = 44). In addition, 53 healthy persons were selected as the control group. The pitents were detected with color Doppler flow imaging (CDFI) and transcranial Doppler ultrasonography (TCD), and the results were analyzed retrospectively. Results: The results of TCD examination of intracranial arteries suggested that the end-diastolic blood velocity in the simple hypertension group and hypertension complicated by cardio-cerebrovascular disease group were significantly lower than that in the control group (P < 0.01); and both the pulsitive index and vascular resistance index were higher than the control group (P < 0.01). The detectable rates of increased carotid intima-media thickness (IMT) and plaques in the group of simple hypertension group were 73.02% (46/ 63) and 50.79% (32/63); the detectable rates of increased IMT and plaques in the hypertension complicated by cardio-cerebrovascular disease group were all 100%, and they were significantly higher than those in the control group [20.75% (11/53) and 19.98% (9/53; P < 0.01)]. Conclusion: Essential hypertension is an important risk factor for intracranial arteriosclerosis. CDFI combined with TCD may objectively evaluate the changes of hemodinamics of intracranial and extracranial arteries in patients with essential hypertension.
