Retrospective analysis of the surgically treated temporal lobe arteriovenous malformations with focus on the visual field defects and epilepsy.

摘要: Background: Authors investigate the surgical outcomes of temporal lobe arteriovenous malformation (AVM) with focus on visual field deficit and seizure. Methods: Between 1981 2004, we experienced 294 cases intracranial AVMs. Among cases, 45 (15.3%) were located in lobe. Twenty-six underwent microsurgical excisions Results: The male-female ratio 26 surgically treated AVMs was 15:11. mean age 34.2 years, ranging from 7 to 63 years. sites lesion classified as polar 1, dorsal 2, laterobasal 15, mediobasal 8. initial symptoms hemorrhage 22 epilepsy 4 cases. Arteriovenous malformations totally removed all patients there no mortality. deficits identified 17 hemorrhage. Massive hematoma that needed emergency operation 5.

Although one patient new postoperative epilepsy, medical controls seizure good 8 patients.
