Abstract:
Objective To investigate the safety and effectiveness of digital subtraction angiography (DSA) in the surgical treatment of intracranial arteriovenous malformations (AVMs) in children.Methods Between December 2015 and February 2017,the clinical and imaging data of 9 children with AVM (2-14 years) underwent hybrid surgery at the Department of Neurosurgery,Xuanwu Hospital,Capital Medical University were analyzed retrospectively.According to the Spetzler-Martin grade,there were 2 patients with grade Ⅰ,3 with grade Ⅱ,2 with grade Ⅲ,and 2 with grade Ⅳ.All the children were treated with microsurgery,and their AVMs were removed by real-time assistance using DSA technique during the operation.The imaging cure rate of surgical treatment and the complications of intraoperative angiography of the children were analyzed.The children were followed up clinically after procedure.According to the modified Rankin scale (mRS) score,their prognoses were evaluated.Results Intraoperative angiography revealed that the AVMs in 8 of 9 children were resected completely,and 1 had a residual lesion,then it was resected completely.Immediately after the resection of the nidi,the angiography confirmed that the nidi of 9 children were resected completely.No related complications caused by intraoperative angiography were observed.Nominal aphasia occurred in 1 child after procedure,and he recovered gradually after 6 months.Pulmonary infection occurred in 2 children,and they were cured after anti-infection treatments.Postoperative follow-up mRS scores were 0-1 in 8 children,2 in 1 child,and no rebleeding was observed.Conclusions In children undergoing AVM surgery,initial observation of DSA is safe and effective.Intraoperative angiography can guide the complete resection of the lesions in real time,improve the surgical cure rate of AVMs,and improve the prognosis of children.
