Abstract：Objective: To discuss the surgical strategy and curative effect of vascular malformation hemorrhage of posterior fossa. Methods: The clinical data of 24 patients, from January 2008 to October 2013, with vascular malformation hemorrhage of posterior fossa were analyzed retrospectively. All patients received preoperative imaging scaning and/or pathologic diagnosis, 15 with arteriovenous malformation, 1 with telangiectasis, 2 with venous malformation, and 6 with dura arteriovenous fistulas (DAVF). Seven cases suffered with subarachnoid hemorrhage (SAH) and 17 cases had posterior fossa hematoma. Results: Eleven cases of the arteriovenous malformation got arteriovenous malformation resection and hematoma evacuation, 2 were treated with endovascular embolization and another 2 got radiotherapy after part arteriovenous malformation resection. The telangiectasis cases and venous malformation patients were performed hematoma evacuation. Four DAVF patients got embolization and 1 got two-stage embolization after hematoma evacuation, and 1 got DAVF excision. Patients were followed up for a period from 6 months to 54 months. Of these patients, the curative effect was excellent in 22, bad in 2. Conclusion: Individualized comprehensive treatment of vascular malformation hemorrhage of posterior fossa can improve efficacy and prognosis.
