Physician-Modified Endograft With Double Inner Branches for Urgent Repair of Supraceliac Para-Anastomotic Pseudoaneurysm

Abstract

Purpose: To demonstrate the feasibility of a physician-modified endograft (PMEG) with inner branches for 2 mesenteric arteries as an alternative to fenestrations or directional branches. Technique: A symptomatic 60-year-old man presented with supraceliac para-anastomotic pseudoaneurysm involving an antegrade aorta to celiac artery and superior mesenteric artery bypass. Since an off-the-shelf multibranched endograft was inappropriate, a Zenith Alpha thoracic stent-graft was modified with 2 inner branches fashioned of 8-mm Viabahn endoprostheses with preloaded guidewires. The procedure was technically successful, and the patient had no postoperative complications. Conclusion: Inner branches might offer an alternative to fenestrations or directional branches in patients with narrow aortas.
