Association of Subclavian Artery Blood Flow with Stroke After Thoracic Endovascular Aortic Repair with Single-Branch Stent Graft

This study underscores the critical importance of maintaining subclavian artery branch patency post-TEVAR to mitigate stroke and re-intervention risks.Clinical ImpactThis study comprehensively investigates the risk of stroke following the reconstruction of subclavian artery branches during thoracic endovascular aortic repair (TEVAR). While previous literature has extensively documented stroke rates associated with the coverage of subclavian artery branches post-TEVAR, reports on stroke following single-branch stent placement are relatively scarce. By analyzing data from patients with inadequate proximal landing zones who received a single-branch stent, this study identifies potential risk factors for stroke and provides a new perspective on postoperative complications specifically related to subclavian artery reconstruction. Our findings significantly contribute to the literature by offering a novel approach to understanding complications after TEVAR, enhancing the precision of risk analysis for postoperative complications.
