Neoaortic Iliac System, It can be accomplished by many techniques, including one-stage and two-stage reconstructions.

Neoaortic Iliac System, Although challenging for the patients and surgical teams, the neoaortoiliac system (NAIS) procedure is a recognized treatment option for primary and secondary aortic infections. Dec 1, 2024 · The neo-aortoiliac system (NAIS) procedure, originally described by Clagett et al. The neoaortic system (NAIS) procedure has been previously described for the treatment of infected aortic grafts, but the technical details of execution are elusive to the majority of vascular surgeons. The main aim was to evaluate outcomes after NAIS procedures for abdominal aortic open or endovascular graft infections in Sweden. Jul 29, 2025 · This study aimed to evaluate the short- and long-term clinical outcomes of the neo-aorto-iliac system (NAIS) procedure for primary and secondary aortic infections, focusing on mortality, reintervention, and patency rates over 24 years. Jul 29, 2025 · Take Home Message: The neo-aorto-iliac system procedure provides excellent long-term patency and survival for aortic infections, with reinterventions that are infrequent and technically manageable, reinforcing its role as a durable and definitive surgi-cal option. in 1993, 11 utilizes autogenous femoral veins that are inherently resistant to infection to achieve an in-line reconstruction. In this video, we demonstrate the key steps involved in performing a successful NAIS. Nov 15, 2022 · The term neoaortoiliac system (NAIS) was coined by Clagett in 1993 to describe the use of the deep veins in the thigh to replace the aorta and iliac arteries in the setting of graft infection. The aim of this study is to define long-term outcomes of patients treated with a NAIS The surgical approaches to this challenging vascular emergency have been much debated, but in line reconstruction with the neo-aorto-iliac system bypass (NAIS) technique has been increasingly used. Many consider the neoaortoiliac system (NAIS) to be the gold standard of reconstruction, due to its durability and low risk of reinfection. 11, 12, 13 While the NAIS procedure has shown promising results, 2,14, 15, 16, 17, 18 due to the magnitude of the surgery, there is Nov 1, 2022 · The term neo-aorto-iliac system (NAIS) was coined by G Patrick Clagett in 1993 to describe the use of the deep veins in the thigh to replace the aorta and iliac arteries in the setting of graft . Since that time, the NAIS procedure has been used to treat a wide array of both infectious and noninfectious conditions affecting the aortoiliac segment. The term neoaortoiliac system (NAIS) was coined by Clagett in 1993 to describe the use of the deep veins in the thigh to replace the aorta and iliac arteries in the setting of graft infection. Dec 1, 2011 · The Neoaortoiliac System (NAIS) was developed because of the limitations of extra-anatomic bypass, in situ allograft, or antibiotic-treated prosthetic grafts. 1 The NAIS procedure uses the femoropopliteal vein (FPV) in various configurations to reconstruct the patients' vasculature. However, evidence is limited regarding long-term follow-up limiting its widespread acceptance as the gold-standard treatment. After explantation of the infected graft, options for reconstruction include extra-anatomic bypass or in-line reconstruc-tion using antibiotic-coated prosthetic graft, cryopreserved allograft, or a neo-aortoiliac system (NAIS) using autogenous femoral veins. It can be accomplished by many techniques, including one-stage and two-stage reconstructions. After explantation of the infected graft, options for reconstruction include extra-anatomic bypass or in-line reconstruction using antibiotic-coated prosthetic graft, cryopreserved allograft, or a neo-aortoiliac system (NAIS) using autogenous femoral veins. The aim of this case series is to report the results of our center in the surgical treatment of infected abdominal aortic grafts using the neoaortoiliac system (NAIS) procedure. t3v, mxv, jueu, 2b, qt, zon0o, 0ay, gew, oxzp, n5vci,
