Abstract:
Objective To investigate the clinical effect of neuronavigation combined with intraoperative ultrasound-assisted microsurgery for the treatment of supratentorial intracranial arteriovenous malformations (AVMs). Methods From March 2014 to February 2017,14 patients with supratentorial intracranial AVMs treated with neuronavigation combined with intraoperative ultrasound-assisted microsurgery at the Department of Neurosurgery,the Second Affiliated Hospital of Anhui Medical University were enrolled retrospectively.According to Spetzler-Martin (S-M)classification,there were 2 cases of grade Ⅰ,6 cases of grade Ⅱ,5 cases of grade Ⅲ,and 1 case of grade Ⅳ. The clinical data,surgical effects,and complications were analyzed. Results (1)The lesions of 13 patients were completely removed and 1 had residue. Four patients had preoperative limb hemiplegia and one had postoperative limb weakness. They were followed up for 1 to 4 years. The myodynamia was improved or returned to normal. (2)One patient had postoperative intracranial infection and was cured after anti-infective treatment. Of the 4 patients with preoperative epilepsy, 3 did not have postoperative recurrence and 1 was controlled. (3)The modified Rankin scale (mRS)scores at 3 months after operation were as follows:8 patients were 0,4 were 1,and 2 were 2. The clinical symptoms and imaging were followed up for 1-4 years,no vascular malformation recurrence and rebleeding were observed. Conclusion The preliminary observation showed that the neuronavigation and intraoperative ultrasound multimodality assisted microsurgical treatment of supratentorial AVMs had the characteristics of accurate location and high safety,and the clinical efficacy was satisfactory.
