395 patients (236 males, mean age 55.6 years: 159 females, mean age 52.2 years) with suspected transient ischaemic attacks or previous strokes underwent intraarterial digital subtraction angiography (IADSA) over a 3-year period ending in March 1991. All procedures were performed via the femoral approach and the majority consisted of arch studies followed by selective catheterization. 253 (64.1%) of the patients had extracranial vascular disease confirmed at angiography. A retrospective analysis of the patients' records was made to extract all possible complications. Complications were defined as any untoward symptoms or signs occurring within 48 h and which could have been related to the angiogram. Neurological complications occurred in 15 (3.89%) patients. 10 (2.5%) patients had transient complications which resolved completely within 24 h. In three (0.8%) patients the neurological deficit was reversible, recovering fully within 6 days. Two (0.52%) patients were left with residual disability from stroke at 10 days. The permanent neurological complication rate is in the lower range of the rates recorded in previous conventional angiographic studies. We conclude that IADSA is a relatively safe and reliable form of investigation in patients with suspected cerebral vascular disease.
在截至1991年3月的3年时间里，395例疑似短暂性脑缺血发作或既往有中风病史的患者（236例男性，平均年龄55.6岁；159例女性，平均年龄52.2岁）接受了动脉内数字减影血管造影（IADSA）检查。所有操作均通过股动脉途径进行，大多数检查包括主动脉弓造影，随后进行选择性导管插入术。253例（64.1%）患者在血管造影时被证实存在颅外血管疾病。对患者的记录进行了回顾性分析，以提取所有可能的并发症。并发症定义为在48小时内出现的任何不良症状或体征，且可能与血管造影有关。15例（3.89%）患者发生了神经系统并发症。10例（2.5%）患者出现短暂性并发症，在24小时内完全缓解。3例（0.8%）患者的神经功能缺损是可逆的，在6天内完全恢复。2例（0.52%）患者在10天时因中风留下了残留残疾。永久性神经系统并发症发生率处于以往传统血管造影研究记录的较低水平。我们得出结论，IADSA是疑似脑血管疾病患者一种相对安全可靠的检查方式。
