Abstract:
Torcular dural sinus malformations (tDSMs) with high-flow fistulas pose complex management challenges due to their vascularity and the delicate neuroanatomy involved. This report presents the case of a child with tDSM and hydrocephalus, who underwent 3 staged embolization procedures but required a redo intervention due to residual malformation and venous hypertension. Utilizing the pressure cooker technique (PCT) in a redo setting allowed for high-pressure, targeted embolic delivery with minimized reflux, achieving near-complete occlusion and significant symptom relief. This case highlights PCT’s potential to improve outcomes in multi-stage treatments of high-flow tDSM, reducing reflux and enhancing safety in technically demanding cases.
