"V" aortoplasty of the proximal descending aorta in the elephant trunk procedure.

ABSTRACT

Complex pathology of the aorta, especially in patients presenting an aneurysm involving the entire aortic arch and proximal descending aorta has been approached in one or two stages. Surgical management of those with an extremely wide diameter of the proximal descending aorta is not yet well defined. The patient in this case was an asymptomatic 47-year-old female with systemic lupus erythematosus (SLE) associated with aneurysm of the ascending aorta, whose aortic arch and descending aorta had presented only overall weakness (examination by inspection and palpation without histological verification). The imaging identified a giant aorta arising at the level of the sinotubular junction (STJ), ending up immediately below the diaphragm. In the first stage she underwent surgical replacement of the entire ascending aorta, aortic arch and proximal part of the descending aorta by combining the elephant trunk with a new type of aortoplasty. In the second stage an endovascular stent graft was inserted into the elephant trunk in the descending aorta. The patient continues to do well 20 months following the repair. In this manuscript type we describe a novel technique of "V" aortoplasty of the proximal descending aorta in order to facilitate the performing of anastomosis between the Dacron graft and aortic aneurysm.
