Balloon occlusion testing for non-sinus-stenosis venous pulsatile tinnitus: A technical case series:
- Pulsatile tinnitus (PT) affects approximately 10% of the population, with venous causes increasingly recognized. Venous balloon occlusion testing (vBOT) is employed to identify symptomatic vessels in non-sinus stenosis venous PT cases.
- vBOT utilizes a transform balloon under fluoroscopic guidance to occlude venous anomalies, allowing for immediate assessment of symptom changes.
- Four case studies show vBOT's success in pinpointing problematic vessels, guiding targeted endovascular coil embolization for significant symptom resolution. Customized approaches are emphasized, particularly for complex cases.
