Initial experience with PMEG-based LSA revascularization seems to offer a valuable, fully endovascular alternative for Zone-2 TEVAR in urgent or emergent cases that can't wait for standard custom-made device manufacturing. Meticulous imaging-guided planning and standardized modification protocols are essential for durable outcomes. While long-term data remain limited, accumulating evidence supports PMEGs as an effective bridge between conventional hybrid approaches and dedicated branched endografts.
