对急性缺血性卒中病人进行血管研究将有助于明确血管闭塞的部位与程度,尤其当考虑做溶栓治疗时,血管状况的资料会有助于对病人进行选择。本文旨在确定CT血管造影(CTA)对临床疑及急性半球缺血病人的作用,并评价其在溶栓治疗的病例选择中的作用。本研究将CTA诊断的准确性与多普勒超声(US)和数字减影(DSA)做了比较。 全组40例,男29例,女11例,平均年龄58.2±13.7岁,均为临床有中～重度大脑半球缺血体征(NIHSS评分≥8分,且无改善趋势)。全组40例均做了CTA,22例做了US,7例做了DSA。本组治疗中20例做了溶栓治疗,其中4例为局部注射尿激酶150万
Vascular studies of patients with acute ischemic stroke will help define the location and extent of vascular occlusion, and especially when considering thrombolytic therapy, information on vascular status may be helpful for patient selection. This article aims to determine the role of CT angiography (CTA) in patients with clinical suspicion and acute hemisphere ischemia and to evaluate its role in the selection of thrombolytic therapy. This study compared the diagnostic accuracy of CTA with Doppler ultrasound (US) and digital subtraction (DSA). The whole group of 40 patients, 29 males and 11 females, mean age 58.2 ± 13.7 years, are clinically moderate ~ severe hemispheric ischemic signs (NIHSS score ≥ 8 points, and no improvement trend). All 40 cases were done CTA, 22 cases done US, 7 cases done DSA. Twenty patients underwent thrombolytic therapy in this group of patients, of whom 4 were locally injected with 1.5 million Urokinase
