三种血管造影方法在自发性蛛网膜下腔出血诊治中的应用

目的 探讨CT、MRI与数字减影血管造影(DSA)在自发性蛛网膜下腔出血中应用,以提高该病诊治水平.方法 回顾性分析本院2008年7月至2010年12月20例自发性蛛网膜下腔出血患者诊治过程.所有患者均先行CT平扫,证实为自发性蛛网膜下腔出血后,再行MRI检查,并进行MRA三维重建以查明原因,对疑有颅内小动脉瘤者行DSA检查并予血管内弹簧圈栓塞治疗.结果 本组自发性蛛网膜下腔出血患者颅内小动脉瘤破裂所致最多,共12例(60%),其次为动静脉畸形破裂所致4例(20%)和高血压动脉硬化3例(15%),另外1例(5%)的患者是烟雾病.12例颅内小动脉瘤患者DSA造影发现动脉瘤后即行血管内弹簧圈栓塞治疗并均达致密栓塞.结论 首先行CT平扫,证实为自发性蛛网膜下腔出血,再行MRI检查,并进行MRA三维重建以查明原因.对疑有颅内小动脉瘤者行DSA检查,DSA造影发现动脉瘤后即行血管内弹簧圈栓塞治疗.是自发性蛛网下腔出血中最优化的诊疗方案,可提高该病诊治水平.

Three types of angiography in diagnosis and treatment of spontaneous subarachnoid hemorrhage

Objective To study the application of the computed tomography (CT), magnetic resonance imaging (MRI) and digital subtraction angiography (DSA) in spontaneous subarachnoid hemorrhage, in order to improve disease diagnosis and therapy. Methods The process of diagnosis and treatment of twenty cases of spontaneous subarachnoid hemorrhage in our hospital from July 2008 to December 2010 were retrospectively analyzed. All patients were examined with CT scan firstly and confirmed spontaneous subarachnoid hemorrhage, further with MRI,and three-dimensional reconstruction of the magnetic resonance angiography of video (MRA) to identify the reasons,suspected small intracranial aneurysms were examined with DSA, and treated with endovascular coil embolization.Results The patients with spontaneous subarachnoid hemorrhage caused by rupture of small intracranial aneurysms had 12 cases(60%). Second, due to arteriovenous malformation in 4 cases (20%) and high blood pressure atherosclerosis in 3 cases (15%), while one case (5%) was moyamoya disease. Twelve cases of small intracranial aneurysms were found endovascular aneurysm after DSA imaging and treated with coil embolization, and reached the dense embolism. Conclusions The patients are examined with CT scan firstly and confirm SAH, further examined with MRI, and three-dimensional reconstruction of the MRA to identify the cause, the suspected small intracranial aneurysms were examined with DSA inspection, aneurysms found by DSA imaging are treated with endovascular coil embolization. The program is the optimal treatment program of spontaneous hemorrhage, can improve the diagnosis and treatment of disease.
