The use of cerebral angiography (ANGIO) to select patients for carotid endarterectomy (CEA) has been limited by concern about the risk of complications of the procedure. The authors sought to determine the rate of neurologic complications at both an academic medical center (AMC) and a community hospital (CH).
The authors reviewed the records of 569 patients undergoing ANGIO. Any documentation of stroke, transient neurologic event, myocardial infarction, or death occurring in the 24 hours after the procedure was recorded. The rate of neurologic complications at the AMC and CH were compared to published studies.
The overall complication rate was 0.5% for stroke and 0.4% for TIA. There was no difference between the AMC and CH. One of the strokes was of moderate severity and four of the five patients with complications subsequently underwent endarterectomy.
The rate of major neurologic complications due to ANGIO may be lower than expected, even when performed in a non-academic setting. Awareness of local ANGIO complication rates is important when selecting patients for CEA.
由于担心脑血管造影术（ANGIO）相关并发症的风险，该技术在选择颈动脉内膜切除术（CEA）患者中的应用受到限制。作者试图确定学术医疗中心（AMC）和社区医院（CH）的神经并发症发生率。
作者回顾了569例接受ANGIO检查患者的记录。记录术后24小时内发生的任何中风、短暂性神经事件、心肌梗死或死亡的记录。将AMC和CH的神经并发症发生率与已发表的研究进行比较。
中风的总体并发症发生率为0.5%，短暂性脑缺血发作（TIA）为0.4%。AMC和CH之间没有差异。其中一次中风为中度严重程度，五名并发症患者中有四名随后接受了内膜切除术。
即使在非学术环境中进行，ANGIO导致的主要神经并发症发生率可能低于预期。在为CEA选择患者时，了解当地ANGIO并发症发生率很重要。
