- W2361221856 abstract "【Objective】 To explore TIA patients intracranial or extracranial blood vessel lesion.【Methods】 Examined 64-slice spiral CT angiography(CTA),Transcranial Doppler(TCD) and color Ultrasonography in the 45 TIA patients,observed the anomal conditions.【Results】 In the 45 TIA patients with examined 64-slice spiral CT angiography(CTA),there are 40 cases of patients and 116 blood vessels with intracranial or extracranial angiostenosis or obstruction.Abnormal rate is 88.9%.The patients of intracranial angiostenosis or obstruction(61.1%) are higher than patients of extracranial angiostenosis or obstruction(38.9%).The patients of extracranial internal carotid are the most in the patients of extracranial angiostenosis(44.4%),however,the patients of intracranial internal carotid are the most in the patients of intracranial angiostenosis(32.3%).Incidence rate(74.2%) of serious angiostenosis or obstruction patients with frequency(≥2/d) and short time(≤1 h) is higher than the patients with infrequent and long time(1 h).The difference of the two groups is statistically significant(P 0.05).Abnormal blood vessels examined patients with TCD(75.6%) is 94.4 % of abnormal blood vessels with CTA.85 blood vessels that Blood flow velocity increased examined with TCD are more than 65 blood vessels examined with CTA.Through color Ultrasonography,the results are carotid arteries angiostenosis or obstruction of 16 cases,35 arteries angiostenosis or obstruction,7 vertebral arteries angiostenosis or obstruction.Detection rate of Carotid arteries or vertebral arteries angiostenosis or obstruction with color Ultrasonography is lower than with CTA.【Conclusion】 Incidence rate of TIA patients intracranial or extracranial angiostenosis or obstruction is high.Abnormal rate examined with CTA is 88.9%.Incidence rate of intracranial angiostenosis or obstruction is higher than extracranial angiostenosis or obstruction.Incidence rate of serious angiostenosis or obstruction patients with frequency and short time is higher than the patients with infrequent and long time.The difference of the two groups is statistically significant." @default.
