The experience of use of intra-arterial digital subtraction angiography(IADSA) was reported, on 100 cases with intracranial diseases. The method of procedure during contrast and interventional treatment was introduced. With the use of IADSA, high resolution image in density could be obtained only using a small quantity of contrast media. IADSA was secure, reliable and useful before and during embolization. It was an good method in diagnosis and treatment of the intracranial diseases especially in cerebrovascular...

The experience of use of intra-arterial digital subtraction angiography(IADSA) was reported, on 100 cases with intracranial diseases. The method of procedure during contrast and interventional treatment was introduced. With the use of IADSA, high resolution image in density could be obtained only using a small quantity of contrast media. IADSA was secure, reliable and useful before and during embolization. It was an good method in diagnosis and treatment of the intracranial diseases especially in cerebrovascular diseases of the brain. (Fig 1~5 see inset P20)

本文报道100例颅内病变数字减影动脉血管造影(IADSA)的检查结果。介绍了IADSA和介入治疗方法。IADSA造影剂用量少、密度分辨力高、安全可靠、实时显像等有利于观察栓塞治疗效果,是颅内疾病特别是颅内血管性疾病较好的诊断和治疗手段。

对经手术证实的20例脑动脉瘤的MRA和IA-DSA的影像进行了对照分析研究,经MRA检出19例(95%)动脉瘤,10mm以下的动脉瘤9例,最小的为4mm,与DSA检出率(19/20)相仿。MRA的定位符合率为84%,低于DSA(95%)。13/19例(68%)在MRA图象上能显示动脉瘤的瘤颈。作者认为MRA是一种新的非侵入性的血管影像方法,可作为脑动脉瘤高危病例的筛选检查,随着MRA技术的进一步完善,MRA有望在神经外科领域替代部分侵入性血管造影检查。

The ability of quickscan(QS)to assess haemodynamically significant lesions in the iliac and femoro-popliteal arteries was studied. Quickscan was prospectively and independently compared to intra-arterial digital subtraction angiography(IADSA) of the if iliac and femoro-popliteal arteries. In 176 patients 757 arterial segments were evaluated. A QS frequency ratio of 1: 3 or greater had a sensitivity of 88%,a specificity of 94% and accuracy of 92% in detecting stenosis>50% diameter (67% area)reduction as shown on IADSA. In the detection of occlusion,QS had a sensitivity of 91%,specificity of 95% and accuracy of 94%. There was significant correlation between area reduction found by QS and the calf/brachial pressure index(CBI) (r=-0. 77,P<0. 01 ). Thirty-seven patients underwent an angioplasty based on QS finding alone. All 37 were successful. The authors conclude that quickscan can provide an inexpensive,quick and non-invasive screening technique for the routine initial assessment of peripheral vascular disease. The results indicate that an agreement with angiography which is as good as duplex scanning. It has potential to replace angiography for workup prior to surgical or catheter intervention,in the assessment of the success of the procedure and its continuing follow-up.

对176名患者的757个动脉段分别做了快速血管扫描(quickscan,QS)及血管造影两项检查。以QS系统血管相邻两点多普勒频移的比率≥1:3作为判断血管存在临界狭窄(血管直径减少50%以上)的阈值。结果:与血管造影结果相比,QS诊断血管临界狭窄的敏感性、特异性和准确性分别为88%、94%和92%;诊断血管闭塞的敏感性、特异性和准确性分别为91%、95%和94%;QS发现血管的狭窄程度与踝肱指数呈明显负相关(r=0.77,P<0.01)。本组中37名患者根据QS检查结果进行了经皮穿刺血管成型术,术中证实病变的存在,效果令人满意。由此表明,在周围血管疾病的诊断中,QS可以作为迅速准确、无创伤、费用低廉的常规检查手段,适合在我国推广应用。
