In access challenged patients, LEAVG and HeRO offer similar rates of secondary patency, infection, and all-cause mortality. The LEAVG required fewer interventions to maintain patency, and the HeRO maintains the benefit of utilizing the upper extremity site of venous drainage. In our practice, we prefer the HeRO to LEAVG, especially in patients with peripheral arterial disease and in the obese population, because it preserves lower extremity access options.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
