[Anterolateral Partial Sternotomy as an Effective Approach for Open Repair After Debranching Thoracic Endovascular...

Thoracic endovascular aortic repair (TEVAR) has become a common minimally invasive option for aortic surgery, often accompanied by debranching of the aortic arch branches. However, TEVAR-specific complications occasionally necessitate open repair. In such cases, especially in patients with complex aortic arch pathology, the choice of surgical approach is critical. In this case, considering the unique background of cold agglutinin disease, we opted for an anterolateral partial sternotomy approach. This approach provided excellent exposure for aortic manipulation and allowed preservation of the existing bypass grafts, contributing to a successful outcome. We believe that this technique can be effectively applied in similar complex cases requiring open repair after debranching TEVAR.
