Abstract:
Objective Meningiomas in the trigone of the lateral ventricle are characterized by deep location and low inci-dence. A few studies have been done on its treatment at home and abroad. This study was to explore the access,techniques,and clini-cal effect of microsurgery for lateral ventricular trigone meningiomas (LVTM). Methods We retrospectively analyzed the clinical data about 36 cases of LVTM treated by microsurgery in our hospital from December 2011 to December 2015. The operation involved lumbar cistern tube drainage, intraoperative drainage of cerebrospinal fluid, a unilateral parieto-occipital U-shaped cut, approach through the interparietal fissure,a sagittal incision about 3 cm long at the interparietal fissure for exposure and resection of the tumor. We followed up the patients for a mean of 17 months postoperatively and analyzed the results and complications. Results Simpson grade I removal of the tumors was achieved in all the 36 cases. Postoperative complications included homonymous hemianopia in 4 cases, central nervous system infections in 3,secondary epilepsy in 2,subcutaneous hydrops in 2,and intratumoral hemorrhage in 1 (which necessitated a second operation). Extended temporal horn of the right lateral ventricle occurred at 32 months after surgery,which was treated by fistulation. Homonymous hemianopia was improved in 2 of the 4 ca-ses. All the patients were capable of daily life activities and none experienced recurrence. Conclusion Sufficient preoperative evalu-ation of the tumor characteristics,rational selection of surgical approach,and expert operation techniques are the key factors for the mi-crosurgical treatment of meningiomas in the trigone of the lateral ventricle.
