Septostomy of septum pellucidum – Salvage technique for reversal of ventricular collapse during pure endoscopic surgical resection of third ventricular colloid cyst

Colloid cysts are benign cystic lesions. Frequently discovered incidentally, they can be severely debilitating and in rare occasions result in sudden death if not managed appropriately. The surgical options for removal include an open approach, as well as minimally invasive, endoscopic approach. Although associated with decreased morbidity, the endoscopic approach at times must be converted to an open procedure. Finding methods to reduce this conversion can help reduce the associated increase in morbidity.
