Abstract: ObjectiveTo review the surgical technique and outcome of intracranial angiographically occult vascular malformations (AOVM) hemorrhage. Methods40 patients with spontaneous intracranial hemorrhage episodes and accepted microsurgery were analyzed retrospectively. ResultsAll AOVMs were successfully resected. No operative death occurred.36 patients were followed up for mean 28 months. CT and/or MRI revealed no residual lesions. Most neurological complications improved postoperatively. 1 case demonstrated rebleeding in surgical site 48 months after operation. Another case, a follow-up MRI scan revealed a contralateral denovo lesion 44 months after operation.ConclusionA current neurosurgical procedure is a satisfactory method to prevents AOVMs rebleeding. Long-term follow-up evaluation is necessary despite the lesion has been totally resected.
