Physician-Modified C3 Excluder Endograft as the Preferred Solution to Treat a Juxtarenal Para-Anastomotic Aneurysm.

Feasibility and early satisfactory results of physician-modified endografts have been reported. Most reports described the use of Cook Dacron aortic endografts (Cook Medical, Inc., Bloomington, IN). However, in some specific anatomic features (short aortic length, narrow aorta), the use of this device may not be appropriate.We here report a case of juxtarenal aortic aneurysm proximal to a former aortobifemoral graft in a high surgical risk patient. Due to a narrow proximal neck and a short aortic length, a physician-modified Gore C3 Excluder device (W. L. Gore & Associates, Inc., Flagstaff, AR) incorporating a fenestration for a large accessory renal artery was implanted. At 6-month follow-up, the aneurysm remains excluded and computed tomography scan demonstrates patent renal vessels.Surgeon-modified Gore C3 Excluder device implantation is feasible. Because of specific device characteristics (short main body, repositioning ability), it represents a valuable alternative in high-risk patients with juxtarenal aneurysms not amenable to other techniques.
