Microneurosurgical resection of third ventricle tumors involving the lateral ventricle through the transcallosal interforniceal approach

Obiective To evaluate the clinical efficacy of microsurgical resection of third ventricle tumors involving the lateral ventricle through the transcallosal interfomiceai approach. Methods From October 2005 to April 2009, 12 patients with third ventricle tumors involving the lateral ventricle received microsurgical resection of the tumors through the transcollasal interfomiceal approach. Results The tumors were totally removed in 4 cases, subtotally in 3 cases and partially in 5 cases without any fatal consequences. Conclusion This approach is safe and effective for removing third ventricle tumors involving the lateral ventricle by accessing the tumor through the anatomical space in the brain, and allows clear exposure of the operative field and causes minimal invasiveness of the surrounding structure with reduced complications.
