The GORE TAG Thoracic Branch Endoprosthesis (TBE) represents an interesting novelty in the management of thoracic aortic pathologies, particularly in urgent settings where left subclavian artery (LSA) coverage is required. By eliminating the need for additional LSA revascularization procedures, this device aims to reduce procedural complexity, operating time, and the risk of complications associated with traditional methods. Clinicians can achieve effective treatment with a single, off-the-shelf device, improving both patient outcomes and procedural efficiency. This case series highlights the potential of an off-the-shelf single-branched thoracic endograft in urgent settings.
