以数字荧光X 线摄影术(DF)为手段的数字减影血管造影(DSA)近几年间进展神速,颇为普及。但静脉DSA(简称IVDSA)不能获得诊断上满意的图像。近来对采用大动脉注射的动脉DSA(简称IADSA)逐渐重视起来。不过它也远非完美无缺,需重新改行传统的脑血管造影者亦不在少数。最近我们施行经肱动脉的选择性脑血管IADSA,获得了不亚于传统脑 In recent years, digital subtraction angiography (DSA) using digital fluorescence radiography (DF) has achieved rapid progress and is becoming more common. However, venous DSA (referred to as IVDSA) can not get a satisfactory diagnosis of the image. Recently, the use of arterial injection of arterial DSA (IADSA) gradually pay attention to it. But it is far from perfect, need to re-divert the traditional cerebral angiography is also a small number. Recently, we performed selective brachial artery IADSA via the brachial artery, obtaining no less than the traditional brain
