Lateral ventricular stenting as a method of preventing trapped temporal horn following resection of lateral ventricular trigone tumor. Case report and review of literature

Abstract

Resection of lateral ventricular trigone tumor can lead the development of specific complication like a trapped temporal horn. Secretion of cerebrospinal fluid from the choroid plexus in closed space leads to progressive enlargement of the temporal horn. The enlargement of the temporal horn leads to lateral transtentorial herniation with brain steam compression, which manifested by disorders of consciousness, hemiparesis, memory impairment and loss of visual fields. The proposed stenting technique allows to prevent the development of extended temporal horn and excludes the requirement its treatment in the long-term period. Over the past year, intraoperative stenting have been performed in five cases. In the long-term period none of the patients have had trapped temporal horn. There was no case of stent dysfunction.The article presents a clinical case of ventricular stenting following resection of lateral ventricular trigone tumor.
