Abstract
Aortic arch aneurysms (AAA) are rare, especially contrasting with the relative prevalence of coarctation of the aorta. These aneurysms can expand rapidly, presenting a greater risk of rupture compared to some other types of aneurysms. Also AAA is linked to other serious complications such as valvular insufficiency or dissection. While a consensus on the best treatment approach is still lacking, extra-anatomic ascending-to-descending aortic bypass grafting via a posterior pericardial approach through a median sternotomy provides a viable alternative. This technique facilitates simultaneous intracardiac repair. We report a case involving a 45-year-old man with coarctation of the aorta and an aortic arch aneurysm. He underwent successful extra-anatomic ascending-to-descending aortic bypass grafting, employing a posterior pericardial approach via a median sternotomy and cardiopulmonary bypass (CPB). This case underscores the feasibility and success of surgical intervention in a patient with coarctation of the aorta and a concurrent, substantial AAA. The use of an extra-anatomical bypass, an innovative surgical technique, has proven to be effective and beneficial in this kind of disease.
