OBJECTIVE: To investigate the techniques and effect of surgical resection of large intra- and extra-ventricular @entity976 via anterior interhemispheric trans-lamina terminalis approach. METHODS: Fifty-two @entity1 who were surgically treated for large intra- and extra-ventricular @entity976 were retrospectively analyzed. All @entity1 underwent surgery via anterior interhemispheric trans-lamina terminalis approach. Of the 52 @entity1 , 28 were male and 24 were female, with age ranging from 3 to 67 years (mean age 33.5 years). The maximum @entity5 diameter varied from 4.0 to 7.8 cm, with mean diameter of 5.1 cm. Contrast-enhanced MRI was underwent to determine the extent of @entity5 resection on the 1 to 3 months after surgery. RESULTS: Total removal of the lesion was achieved in 47 cases (90.4%), 5 @entity1 underwent subtotal resection (9.6%). Division of the anterior communicating artery was performed in 6 @entity1 with no early or late complications related to division of the artery. Visual acuity was preserved or improved in 44 @entity1 (84.6%). Preservation of the pituitary stalk were achieved in 33 @entity1 (63.5%). No surgery-related @entity204 occurred. The postsurgical follow-up period varied from 3 months to 68 months (mean 25.4 months). Twenty-three cases had endocrinological deficit and received some form of hormonal replacement after surgery. Permanent @entity2010 occurred in 18 cases. Three @entity1 died and 6 @entity1 suffered recurrence during the followed-up period. CONCLUSIONS: The anterior interhemispheric approach, with opening of the lamina terminalis, is a valid choice for large intra- and extra-ventricular @entity976 . These @entity5 can be removed without significant sequelae related to the surgical approach because optic nerves, optic chiasm, internal carotid artery, hypothalamic structures and pituitary stalk can be seen and effectively protected.
