目的:讨论旋转DSA在临床上的技术应用和优点。方法:35例脑血管和肝动脉造影患者行普通DSA,其中24例患者行旋转DSA检查。结果:普通DSA,脑血管造影只能在正侧位上观察到部分病变,通过旋转DSA和工作站的三维重建可以清晰显示病变结构及周围解剖;对于肝脏肿瘤的肝动脉造影可清楚的显示肿瘤的供血动脉,是普通DSA无法做到的。结论:旋转DSA技术对脑血供及肝脏肿瘤的诊断和治疗具有很高的指导价值.
Objective: To discuss the clinical application and advantages of rotating DSA. Methods: Thirty-five patients with cerebrovascular disease and hepatic arteriography underwent routine DSA. Twenty-four patients underwent rotational DSA. Results: The common DSA and cerebrovascular angiography showed only partial lesions in the anteroposterior position. The three-dimensional reconstruction of the DSA and the workstation could clearly show the lesion and the surrounding anatomy. The hepatic artery angiography of liver tumors could clearly show the tumor Blood supply artery, can not be done by ordinary DSA. Conclusion: Rotational DSA has high guiding value in the diagnosis and treatment of cerebral blood supply and liver tumors.
