摘要 目的探讨蛛网膜下腔出血(subarachnoid hemorrhage,SAH)患者首次数字减影血管造影(digital subtractionangiography,DSA)呈阴性的原因及诊疗策略。方法对近年来44例首次DSA呈阴性的SAH病人的临床资料进行回顾性分析,并在出血后2~3周进行DSA复查,分析其阴性结果及原因。结果 DSA阴性组在性别、年龄、Hunt-Hess分级及Fish-er分级、高血压诱因与DSA阳性组比较差异均有统计学意义(P<0.05);对首次DSA阴性患者2~3周后行DSA复查,6例诊断为动脉瘤或血管畸形,脑周围非动脉瘤性蛛网膜下腔出血(PNSAH)患者14例中,复查DSA亦无阳性发现,20例患者原因不明。结论对首次DSA检查结果呈阴性的SAH病人,中脑周围非动脉瘤性蛛网膜下腔出血临床过程及预后相对良性,可不必重复造影。其余患者均应在2~3周后行DSA或CTA、MRA复查,甚至手术探查,预后相对于动脉瘤性蛛网膜下腔出血亦良好。
