An 83-year-old man who had undergone aortic arch repair using the elephant trunk technique in addition to abdominal aorta repair required surgical intervention for a pseudoaneurysm at the distal anastomosis of the aortic arch graft. Due to marked adhesion around the aneurysm, aortic cross-clamping was not feasible. Thus, under femoro-femoral partial bypass, the arch prosthesis was endoclamped using an aortic occlusion balloon inserted through the left femoral artery into the aortic arch graft and through the elephant trunk, guided by fluoroscopy and transesophageal echocardiography. This allowed descending aorta replacement with minimal bleeding. His postoperative course was uneventful. This technique enabled safe and bloodless clamping of the proximal portion of the aortic arch graft.
