Over a two-year period, 167 patients with symptoms of transient ischaemic attacks or suspected minor stroke underwent intravenous digital subtraction angiography (DSA) of the carotid arteries. There were no major complications. Ninety-six patients had abnormal angiograms, 60 normal studies, and in 11 patients (7%) the examination was not of diagnostic quality, mostly because of motion artifacts. In 86 patients no therapeutic consequences resulted from the DSA examination. Twenty-six patients were referred for vascular surgery, and 34 patients had either anticoagulation or aspirin therapy. In 10 patients a primary medical cause was found for their cerebral vascular symptoms. It is concluded that intravenous DSA of the carotid arteries in patients with transient ischaemic attack is a safe, diagnostically useful procedure, that can also be used on an outpatient basis.
在两年期间，167例有短暂性脑缺血发作症状或疑似轻度中风的患者接受了颈动脉静脉数字减影血管造影（DSA）检查。未发生重大并发症。96例患者血管造影异常，60例检查正常，11例患者（7%）的检查结果不具有诊断价值，主要是由于运动伪影。86例患者的DSA检查未产生治疗后果。26例患者被转诊接受血管手术，34例患者接受了抗凝或阿司匹林治疗。10例患者的脑血管症状找到了原发性医学病因。结论是，短暂性脑缺血发作患者的颈动脉静脉DSA是一种安全、具有诊断价值的检查方法，也可在门诊进行。
