OBJECTIVE: To present an initial experience with a new modular transfemoral multibranched stent-graft for treating aortic arch aneurysms.
METHODS: Six patients, considered high risk for open surgery, were treated with a custom-made branched stent-graft. Two patients had aortic arch aneurysms, three had descending thoracic aortic aneurysms involving the distal arch, and one had a saccular aneurysm of the arch adjacent to the origin of the innominate artery. All patients had undergone a staged left carotid subclavian bypass before the endovascular procedure. Each branched graft had a 12-mm side branch for the innominate artery and an 8-mm side branch for the left common carotid artery. The branches were extended into their respective target arteries with covered self-expanding stents.
RESULTS: Aneurysm exclusion without endoleak was successful in 5 of the 6 patients, and 11 of the 12 target vessels were successfully cannulated and preserved. Patient 1 developed a type I endoleak that was managed successfully with coiling and gluing of the aneurysm sac. Patients 2, 3, 5, and 6 had uneventful placement of the prostheses, with successful exclusion of the aneurysm sac. In patient 4, cannulation of the innominate branch was unsuccessful, and an extra-anatomic bypass was necessary to perfuse the right carotid and vertebral arteries.
CONCLUSIONS: We have demonstrated the technical feasibility of a modular transfemoral branched stent-graft for treatment of aortic arch aneurysms. Our initial experience has shown that the method is relatively safe. Long-term follow-up is necessary to evaluate the efficacy and safety of this new device.
