Actual (reported)The goal of this multicenter, observational cohort study is to evaluates the clinical effectiveness of a single-renal scallop custom-made stent-graft (TREO, Terumo Aortic, Sunrise, FL) to treat "hostile" AAA with mismatched renal arteries as actual standard of care in this Vascular Unit The main question it aims to answer are: if a dedicated devices could improve the results in the endovascular treatment of patients suffering to infrarenal abdominal aortic aneurism with a mismatched takeoff of the renal arteries. Participants responding to inclusion criteria will be treated as best clinical practice with a custom made device with a single scallop for the renal artery. The minimum follow-up requested, as standard clinical practice, was: 3-months, 12-18 months- and 5-years CTA; clinical and DUS examination at 6- and 12- and 36-months after the intervention and yearly thereafter. No comparison group was present.

Actual (reported)Evaluation of the clinical effectiveness of the endovascular exclusion of infrarenal Abdominal Aortic Aneurysm with a single renal scallop endograft
Clinical effectiveness measured in terms of technical and clinical success. Technical success was defined as successful introduction and deployment of the device in the absence of surgical conversion or mortality, type I or III endoleaks, or graft limb obstruction. A technical success thus implies the following qualifying details: 1. Successful access to the arterial system using a remote site; 2. successful deployment of the endoluminal graft with secure proximal and distal fixation; 3. absence of either a type I or III endoleak; 4. patent endoluminal graft without significant twist, kinks, or obstruction by intraoperative measurements; 5 patency of both renal arteries and at least one hypogastric artery.

Patients suffering to AAA with a mismatched takeoff (\>10mm) of the renal arteries
Techniques for delivery and deployment of the standard device have been well described by different papers, but for the "prototype" some attention is required. Once the device was advanced at the level of the lowest RA the C-Arm has been moved to correct the parallax effect and positioned orthogonally to the origin of the artery. This procedure permits perfectly matching the scallop with the artery takeoff. A selective angiogram was performed to assure the patency of the lower RA. After the deployment of the main body proper iliac extensions were delivered to completely exclude the aneurysm as standard practice.
