A New Off-Pump Hybrid Open and Endovascular Repair to Treat Ductus Botalli and Ascendens Aneurysms

Abstract

To report a combined ascending aorta and aortic arch hybrid repair, we performed off-pump with no aortic graft replacement. A 65-year-old man, developing progressive recurrent laryngeal nerve paralysis, underwent a computed tomography (CT) angiography detecting nonpatent residual ductus Botalli aneurysm and ascending aorta aneurysm. Due to severe multimorbidities, a less-invasive alternative was elaborated. In a first step, appropriate proximal landing zone for aortic stent grafting was achieved by ascending aorta diameter reduction, with epiaortic wrapping, and debranching the supra-aortic trunks. In the second step, endovascular stent grafts were deployed from proximal ascending aorta to descending aorta, excluding the ductus Botalli aneurysm. Six-month follow-up CT shows ductus Botalli aneurysm exclusion, stable stent graft position, and ascending diameter and patent and stenosis-free supra-aortic grafts. This case supports this alternative treatment to open aortic repair under circulatory arrest and deep hypothermia, especially in those patients considered unfit for such invasive treatment.
