A contralateral transfalcine transprecuneus approach for resection of meningiomas in the atrium of lateral ventricle

Abstract

Objective To explore the safety and efficacy of meningiomas in atrium of lateral ventricle with contralateral transfalcine transprecuneus approach. Methods Four patients with meningiomas in the atrium of the lateral ventricle, admitted to our hospital from August 2015 to February 2017, were chosen in our study; two of the meningiomas were at the left side and two of them were at the right side; the diameters of meningiomas were of 2-4 cm. Resection via contralateral transfalcine transprecuneus approach was performed on these meningiomas in the atrium of the lateral ventricle. A retrospective study on their clinical data and efficacies was performed. Results Complete resection was achieved in all patients enjoying Simpson grading I. Postoperative pathology revealed 3 with meningiomas of fiber type and one with meningioma of mixed type. No postoperative visual field damage or sensory aphasia was noted. One patient with dizziness before operation was completely relieved after operation. No recurrence of postoperative epilepsy after half a year of antiepileptic treatment was noted in one patient with preoperative epilepsy. All the 4 patients had no recurrence and no new symptom during the 2-18 months of follow-up. Conclusion The contralateral transfalcine transprecuneus approach is appropriate for most lesions of 2-4 cm in the atrium of the lateral ventricle, enjoying good safety and efficacy.
