Of 440 patients with spontaneous subarachnoid haemorrhage in whom an aneurysm was suspected, 60 had a negative angiogram. A second angiogram performed 1-4 weeks later revealed an aneurysm in 5 of 40 cases. Of these patients, 3 had a second haemorrhage. In all cases, diffuse bleeding, with involvement of the anteroinferior interhemispheric fissure, was present on CT. There were three aneurysms of the anterior communicating artery and two of the carotid siphon. The reasons for the false-negative angiograms and the usefulness of repeated angiography are discussed.
在440例疑似患有动脉瘤的自发性蛛网膜下腔出血患者中，60例血管造影结果为阴性。1 - 4周后进行的第二次血管造影显示，40例中有5例存在动脉瘤。在这些患者中，3例再次出血。所有病例的CT检查均显示弥漫性出血，累及前下半球间裂。有3个前交通动脉动脉瘤和2个颈内动脉虹吸部动脉瘤。文中讨论了血管造影假阴性的原因以及重复血管造影的作用。
