Skill and Selection of Approach of Microsurgery for Lateral Ventricular Tumors

Objective To explore the microsurgical skill and approaches in the patients with lateral ventricle tumors. Methods A retrospective analysis was performed in 33 patients with lateral ventricle tumors, of whom, 7 underwent the microsurgery through transfrontal cortrex approach, 4 through transcallosal approach, 15 through transparieto-occipital cortrex approach, and 7 through transtemporal cortrex approach. Results of 33 patients, 20 received total resection of the tumors, 7 subtotal resection and 6 partial resection. The pathological examination showed that of 33 tumors, 16 were meningiomas, 10 ependymomas, 5 gliomas, and 2 chroid plexus papillomas. The postoperative complications included hydrocephalus in 4 patients, hemiparesis in 4, hemianopia I n 2, intracerebral hematoma in 1 and epilepsy in 1. Of 31 patients followed up from 4 months to 6 years (mean, 3.7 years), 18 were recovered very well, 9 could live without the other help, 2 lived with the other help and 2 died of tumor recurrence 1 year after the operation. Conclusion The curative effect of the skillful microsurgery through the proper approach on the patients with lateral ventricle tumors is good.
