目的通过回顾性分析我院10年来收治的21例原发性脑室出血型Moyamoya病患者的临床资料,探讨非高血压性原发性脑室出血与Moyamoya病及其影像学特征的关系。方法对我院神经外科10年来确诊的原发性脑室出血Moyamoya病患者的CT、DSA和临床治疗进行回顾性分析。结果 25例非高血压性原发性脑室出血患者中DSA证实21例为Moyamoya病。3例合并基底动脉动脉瘤。所有患者出血侧均存在脉络膜前动脉异常扩张扭曲及异常分支。该组患者首次治疗均获得良好结果。结论 Moyamoya病是成人非高血压性原发性脑室出血的主要病因,对成人非高血压性原发性脑室出血应常规行DSA明确是否存在Moyamoya病。成人非高血压性原发性脑室出血与脉络膜前动脉的扩张扭曲或异常分支密切相关,并且后者可作为前者的预测指标。
Objective To investigate the relationship between non-hypertensive primary ventricular hemorrhage and Moyamoya disease and its imaging characteristics by retrospectively analyzing the clinical data of 21 patients with Moyamoya disease who have been admitted to our hospital over the past 10 years. Methods The CT, DSA and clinical treatment of patients with Moyamoya disease who had been diagnosed as primary ventricular hemorrhage in our hospital for 10 years were retrospectively analyzed. Results DSA confirmed 25 cases of Moyamoya disease in 25 patients with non-hypertensive primary ventricular hemorrhage. 3 cases with basilar artery aneurysm. All patients with abnormal side of the anterior choroidal artery there is an abnormal expansion of the distorted and abnormal branches. The first treatment of this group of patients achieved good results. Conclusions Moyamoya disease is the major cause of non-hypertensive primary ventricular hemorrhage in adults. DSA should be routinely performed in adults with non-hypertensive primary ventricular hemorrhage to determine whether there is Moyamoya disease. Adult non-hypertensive primary ventricular hemorrhage is closely related to the dilated or abnormal dilation of the anterior choroidal artery, and the latter can be used as a predictor of the former.
