蛛网膜下腔出血的数字减影全脑血管造影133例分析

摘要：目的探讨蛛网膜下腔出血的数字减影全脑血管造影的临床效果。方法选择我院2008年10月至2012年10月蛛网膜下腔出血患者共133例，上述患者诊断符合中国第四届脑血管病学术会议制定的蛛网膜下腔诊断标准，本组患者实施数字减影全脑血管造影检查，对本组患者所得相关资料进行分析，观察不同年龄段下动脉瘤、动静脉畸形、动脉炎和烟雾病诊断情况，并与临床确诊进行对比。结果本组133例蛛网膜下腔出血患者均实施数字减影全脑血管造影检查，其中101例患者确诊，数字减影全脑血管造影诊断蛛网膜下腔出血病因确诊率为75．9％。其中数字减影全脑血管造影诊断确诊动脉瘤有79例，所占比例为59．3％、确诊的动静脉畸形有14例，所占比例为10．5％、确诊的动脉炎有5例，所占比例3．7％、确诊的烟雾病有3例，所占比例为2．5％。结论颅内动脉瘤是导致蛛网膜下腔出血的主要病因，而数字减影全脑血管造影是诊断蛛网膜下腔出血病因中最直接和最可靠的检查措施，值得借鉴。

Clinical analysis of digitia subtraction angiography to SAH in 133 cases

Objective To evaluate the clinical effectiveness of digital subtraction angiography to SAH. Methods The data of 133 cases of patients with SAH were reviewed from Oct. 2008 to Oct. 2012. They all meet the standard of diagnostic indicators of SAH setted by the forth cerebrovascular disease academic conference . The clinical presentation under the different ages were observed and compared with the clinical diagnosis. Results In the 133 cases of digital subtraction angiography（DSA）, 101 cases have confirmed. Positive rate was 75.9%. DSA indicated 79 patients had an eurysm, which took 59.3%, 14 patients had arteriovenous malformation , which took 10.5%, 5 patients had arteritis, which took 3.7 % and 3 patients had moyamoya disease, which took 2.5 %. Conclusion Intracranial aneurysm was the main cause to SAH,which could be found by the technology of DSA directly and effectively.
