目的 探索数字减影血管造影术(DSA)对自发性蛛网膜下腔出血(SAH)病因诊断的价值。方法分析25例SAH患者的DSA检查结果,绝大多数患者均经CT、MRI及腰穿脑脊液证实。结果 25例SAH中,颅内动脉瘤12例(48％),血管畸形7例(28％),动脉硬化3例(12％),动脉炎1例(4％),正常2例(8％)。结论 脑血管造影(DSA)是SAH病因的经典确诊手段,有条件者均应在SAH后3d内或3周后进行DSA检查,有利于病因诊断和治疗。CT对SAH定性、定位,对急诊病人的治疗具有重要参考价值。
Objective To explore the value of digital subtraction angiography (DSA) in the diagnosis of spontaneous subarachnoid hemorrhage (SAH). Methods The DSA results of 25 patients with SAH were analyzed. The majority of patients were confirmed by CT, MRI and lumbar puncture cerebrospinal fluid. Results In 25 cases of SAH, 12 cases (48%) had intracranial aneurysm, 7 cases (28%) had vascular malformation, 3 cases (12%) had arteriosclerosis, 1 case ). Conclusions Cerebral angiography (DSA) is a classic diagnostic method for the etiology of SAH. All patients should have DSA examination within 3 days or 3 weeks after SAH, which is helpful for the diagnosis and treatment of etiology. CT of SAH qualitative, positioning, the treatment of emergency patients has an important reference value.
