Background: Venous sinus stenting (VSS) is a safe and effective treatment strategy for pulsatile tinnitus (PT) and idiopathic intracranial hypertension (IIH). Although complications are rare, the morbidity associated with the complications is high. Navigating through the venous sinuses poses unique challenges to the interventionalist. There is limited literature regarding device selection to maximize safety and efficiency. We report on the safety and advantages of using a balloon guide catheter (BGC) for venous access in VSS.
Methods: Retrospective analysis of all patients undergoing VSS using a BGC over a three-month period.
Results: A total of 22 patients were included in the analysis (median age 35; 21 female). The indication for treatment was PT in 10 patients and IIH in 12 patients. The BGC was navigated into the sigmoid and transverse sinuses, enabling successful delivery of the stent in all cases. The BGC balloon was inflated 23 times for navigating past tortuosity or obstructions, and for anchoring. There were no intraprocedural complications.
Conclusions: The use of BGC in VSS is safe and feasible. BGCs have features that can be utilized to overcome the unique challenges encountered during VSS.
