Abstract:
Objective To evaluate the value of CT plus CTA in emergency surgical treatment of spontaneous intracerebral hemorrhage caused by brain arteriovenous malformations(AVM). Methods A total of 15 cases diagnosed with spontaneous intracerebral hemorrhage by emergent CT examination in the Second Affiliated Hospital of Wenzhou Medical University were retrospectively reviewed from May 2015 to June 2018, and subsequent emergent CTA examination was adopted to verify whether the patients had brain AVM that was responsible for the hemorrhage. After diagnosis, emergency surgical resection of the brain AVM and evacuation of hematoma were performed. Glasgow outcome score (GOS) was used to evaluated the outcome. A secondary DSA or CTA was performed from 2 weeks to 6 months post the operation. Results All 15 cases exanimated by emergent CT plus CTA were demonstrated to have brain AVM and intracranial hematoma. All the patients received emergency brain AVM resection and hematoma evacuation. The surgical finding during operation was in line with what was seen on emergent CT plus CTA, and all cases got total hematoma evacuation. Twelve cases received total brain AVM resection, and the other 3 cases received partial resection because the residual AVM foci existed in deep brain structures . After the operation, none had rebleeding at the surgical site. Follow-up DSA or CTA confirmed the 12 cases had total resection and the other 3 cases had partial resection. All patients were alive after the surgery and GOS scores during the follow-up time, from 2 weeks to 6 months after emergency surgery, were: 5 in 6 patients, 4 in 4 patients, 3 in 4 patients and 2 in 1 patient. Conclusions CT plus CTA can better show the relationship between vascular malformation, hematoma, and the adjacent anatomical structure, and therefore may contribute to intraoperative judgment and complete resection of vascular malformation. It is a practical imaging tool for the preoperative evaluation and emergency surgical treatment of spontaneous intracerebral hemorrhage caused by brain AVM.
