Clinical analysis of the resection of intracranial cavernous malformation complicated with venous malformation

Abstract

Objective To preliminarily discuss the operation strategy in patients with intracranial cavernous hemangioma complicated with venous malformation. Methods The clinical data and postoperative follow-up results of 13 patients with intracranial cavernous hemangioma complicated with venous malformation operated at the Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University from January 2007 to December 2014 were analyzed retrospectively. Results In the 13 patients, intracranial cavernous malformation complicated with venous malformation achieved total resection in 7 patients. They all developed severe cerebral edema after procedure. Four of them were in the supratentorial region, their prognoses were good after strengthening dehydration treatment, and 1 in the supratentorial region died, and 2 left sequelae. The postoperative condition was stable and the prognosis was good in 4 patients whose abnormal expansion of medullary veins were resected, the main drainage veins were retained and in 2 patients whose venous vascular malformations were retained. Conclusion In the operation of resection of intracranial cavernous malformation complicated with venous malformation, the resection of abnormally dilated medullary veins and retaining main draining veins at the same time of the total resection of cavernous malformation are more conducive to the rehabilitation of patients.
