Abstract：Objective To explore the key points and outcomes of intraoperative ultrasound-assisted emergent microsurgery on large cerebral ateriovenous malformations(AVMs)with hemorrhage.Methods We analyzed retrospectively a clinical data of 15 patients with large cerebral AVMs with hemorrhage. Of whom, 4 had Spetzler-Martin grade Ⅲ AVMs, 8 grade Ⅳ and 3 grade Ⅴ. All the patients underwent emergent microsurgery under the guide of intraoperative ultrasound.Results The large cerebral AVMs were totally removed in 13 cases(86.7%), and subtotally in 2. The postoperative complication included small intracranial hematoma in 3, status epilepticus in 2, communicating hydrocephalusin 2 and hemiparalysis in 1. Two patients died. The following up of 6 to 12 months showed that of 13 patients, 9 belonged in activity of daily living grade I, 1 grade Ⅱ, 1 grade Ⅲ and 2 grade Ⅳ. Conclusions The intraoperative ultrasound-assisted emergent microsurgery is a safe and effective method to treat large cerebral AVMs. The risk of the operation can be reduced and the curative effect can be improved by good understanding of the the structure of the vascular malformation and hemodynamic characteristics through preoperative 3D-CTA and DSA.
