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. ln 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-aoftic trunk. ln the second step, endovascular stent grafts were deployed from proximal ascending aorta to descending aofta, 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-aoftic 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.
