三维DSA与MRI或CT融合技术在颅内动静脉畸形治疗中的应用价值

Evaluation of fusion technology of three-dimensional DSA with MRI or CT in the treatment of intracranial arteriovenous malformations

目的 探讨三维数字减影血管造影（DSA）与MRI或CT融合技术在颅内动静脉畸形治疗中的临床应用价值.方法 随机选取2013年7月至2015年7月颅内动静脉畸形（AVM）患者28例,所有患者均经DSA明确诊断,并分别接受MRI或CT检查,实施三维DSA与CT或MRI融合结合诊断,对患者的临床治疗资料进行回顾性分析.结果 20例患者行三维DSA与MRI融合,8例患者接受三维DSA与CT融合,其中20例患者畸形团直径〈3 cm,4例畸形团直径3-6 cm,4例为小脑部位动静脉畸形;所有患者均顺利完成治疗,术后未见严重并发症.结论 术前影像融合作为一种有效的辅助手段,可为AVM患者治疗方案的制定提供可靠建议,有利于对患者开展针对性治疗,促进其预后的改善.

Objective To investigate the clinical application value of fusion technology of three-dimensional intracranial digital subtraction angiography （DSA） and CT or MRI in the treatment of intracranial arteriovenous malformations.Methods From July 2013 to July 2015,28 patients with intracranial arteriovenous malformations （AVM） were randomly selected,all patients were confirmed by DSA diagnosis and were treated with MRI or CT scan,and the implementation of three-dimensional DSA and CT or MRI fusion diagnosis,and the clinical data were retrospectively analyzed.Results In this study,three-dimensional DSA and MRI fusion were performed in 20 patients,8 patients underwent three-dimensional DSA and CT fusion.Among the 28 cases,the malformation diameter under 3 cm in 20 cases,the malformation diameter was 3-6 cm in 4 cases,4 cases of cerebellum arteriovenous malformation.All patients were successfully treated and no serious postoperative complication was found.Conclusions Preoperative imaging fusion as an effective adjunct to provide reliable recommendations for the development of AVM patient treatment programs,it is beneficial for the patient to carry out targeted therapy,contributes to improving their prognosis.
