RESUMO
BACKGROUND: tumors of the lateral ventricle are rare lesions in general neurosurgical practice; they account for < 1% of intracranial tumors. Complete microsurgical resection has been the treatment of choice for these lesions, either via the trans-cortical or trans-callosal route. The surgeons must choose the way that will cause least morbidity, provide adequate working space, and achieve a complete resection by surgery for these deep lesions
AIM OF THE WORK: was to evaluate the available different surgical modalities for the management of difference lateral intra-ventricular tumour types in various locations within the lateral ventricles
PATIENTS AND METHODS: this study was carried out on 23 patients with different lateral intra-ventricular tumour types in various locations within the lateral ventricles, the two approaches were transcallosal and trancortical approaches
RESULTS: regarding Intra-operative complications in the two groups, injury to adjacent vital structure was the most common complication [9, out of 23 patients= 39.13%], followed by bleeding [8 out of 23 patients 34.78%], and lastly brain edema [6 out of 23 patients= 26.09%]. Regarding tumour resection, total resection was achieved in 15 out of 23[65.2%], partial resection was performed in 8 out of 23 [34.8%] and was due to bleeding in 3 patients, brain edema in another 3 patients, and vicinity to a vital structure or eloquent area in the last 2 patients. Regarding postoperative complications in the two groups, seizure was the striking post-operative complication in patients operated via the transcortical approach [10 out of 14 patients = 71.4%]. Likewise, the post-operative brain edema was prominent among the patients of transcortical approach [7 out of 14 patients 50%]. On the contrary, the post-operative complication of obstructive hydrocephalus was the hallmark among the transcallosal approached patients [6 out of 9 patients= 66.7%]
CONCLUSIONS: tumor location within the lateral ventricle was the main factor for choosing the most pppropriate operative approach. However, the chosen operative corridor should optimize tumor access and protect vulnerable neurovascular structures
