Different Configurations of Neoaortoiliac System Operation: An Institutional Experience

Background: Mycotic aortic aneurysm of the abdominal aorta is a rare entity. Repair of infected aneurysms is challenging because of the deleterious consequences of the usage of prosthetic material as an arterial conduit with limited availability of autogenous grafts. Aortic graft infection is one of the most morbid complications in vascular surgery. The main objective in treating aortic graft infection is to remove the infected graft material, thoroughly debride, and re-establish the vascular continuity. Neo-Aortoiliac system operation utilizes the femoropopliteal vein in various configurations, depending on the extent of infection and the availability of the conduit. Aim: This article aims to report our experience of various configurations of Neo aortoiliac system operation and various conduits used along with femoropopliteal vein, when the femoropoliteal vein is inadequate. Materials and Methods: The study was performed in a single tertiary care center. Between January 2022 and June 2023, 4 cases of Neo aortoiliac system operation were performed. The demographics, clinical presentation, operative data, and postoperative outcomes were subsequently collected and analysed. Results: 3 out 4 patients of Neo-Aortoiliac system operation survived, one patient had Major Adverse Limb Event and one patient succumbed to death due to sepsis.
