Abstract：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.
