Endovascular balloon usage in endoscopic third ventriculostomy for hydrocephalus during a national shortage: case...

Endoscopic third ventriculostomy (ETV) is a well-established surgical technique for treating hydrocephalus. Many providers have transitioned to utilizing the specialized Neuroballoon for the stoma dilation in ETV; however, these devices are intermittently unavailable during supply chain shortages. We present the experience of employing cardiac angioplasty and neurovascular balloons as substitutes for the Neuroballoon in 3 patients. The scepter balloon (Microvention), priced at $1800 compared to the standard $300 Neuroballoon (Integra), proved effective, but its pliability presented technical challenges. The substantial cost differential compared to a Neuroballoon ($300) raises economic considerations. The Cardiac TREK balloon (Abbott) was similarly effective, while also being easier to manage endoscopically and cheaper at $158. These experiences support the viability of non-neuroendoscopic specialized balloons as alternatives for ETV dilation of the floor of tuber cinereum.
