作者对有症状的椎动脉夹层分离患者作了回顾分析,旨在确定复式超声检查和经颅多普勒超声检查(TCD)在椎动脉无创伤性诊断中的价值。 对象为由脑血管造影证实的椎动脉夹层分离患者10例(男8,女2,24～58岁,平均36岁)。病人都作了脑血管造影、复式超声检查、TCD、头颅CT或MRI。 10例中CT检查有6例阳性。7例做了MRI,CT阴性的病人中有2例MRI阳性。共发现小脑梗塞6例,延髓外侧梗塞3例,2例CT和MRI正常。
The authors retrospectively analyzed patients with symptomatic vertebral artery dissection to determine the value of duplex and transcranial Doppler ultrasonography (TCD) in noninvasive vertebral artery diagnosis. The subjects were confirmed by cerebral angiography in 10 cases of dissection of vertebral artery dissection (male 8, female 2,24 to 58 years, mean 36 years). All patients underwent angiography, duplex ultrasound, TCD, cranial CT or MRI. CT examination in 10 cases were positive in 6 cases. Of the 7 patients who had MRI, 2 were MRI positive in patients with CT negative. A total of 6 cases of cerebellar infarction were found, 3 cases of lateral medullary infarction, 2 cases of normal CT and MRI.
