Hybrid Coils for Left Subclavian Artery Embolization During Zone 2 Thoracic Endovascular Repair

The POD is an effective tool for LSA embolization during TEVAR. This occlusion system offers a promising alternative to traditional methods by overcoming anatomical limitations, potentially eliminating the need for large introducers in upper extremity access and reducing the number of coils required for permanent occlusion of a high-flow vessel.Clinical ImpactThe Penumbra Occlusion Device (POD) represents a practical alternative to conventional coil or plug embolization for large, high-flow vessels. Its design allows controlled deployment through small-caliber access, potentially simplifying the procedure and reducing the number of devices required. This study demonstrates high technical success and acceptable short-term outcomes, suggesting that the POD can achieve reliable left subclavian artery occlusion during Zone 2 TEVAR. These results may guide procedural planning and support wider adoption of the POD as a feasible option in this setting.
