Objective: To evaluate 2 different aortic endograft systems with suprarenal fixation in patients with unfavorable neck morphology.
Methods: A prospective observational study assigning patients with abdominal aortic aneurysm with unfriendly neck anatomy treated with 2 different endograft systems (Endurant and Zenith) was conducted. The log-rank test was applied to investigate the differences in cumulative outcome parameters.
Results: Successful endograft implantation was achieved in all patients. Requirement for troubleshooting techniques was similar in the 2 groups (P = .156 and P = .081, respectively). In-hospital procedure-related morbidity occurred in 7 patients (Zenith vs Endurant, P = .690). Freedom from any type of endoleak and overall mortality did not differ significantly between the groups (log-rank test, P = .068 and P = .087). Reinterventions were more commonly required in the Zenith group (log-rank rest, P = .041), and were all nongraft/aneurysm-related.
Conclusions: Similar performances of the Zenith and the Endurant endograft systems were demonstrated.

Purpose: To demonstrate the Modified Balloon Nose Cone Technique to avoid passage of the aortic valve in endovascular branched arch repair.
Technique: The technique is demonstrated in a 54-year-old patient after previous open repair of the ascending aorta and mechanical aortic valve replacement due to type A aortic dissection. The delivery system of a custom-made stent-graft with 3 inner branches was modified by subtotally sawing off its nose cone.

Purpose: To present endovascular management of an intraoperative type IIIc endoleak (EL) in a patient with migration of the right renal artery (RRA) bridging stent graft (BSG) during branched aortic aneurysm repair.
Technique: The technique is demonstrated in an 80-year-old woman who underwent branched endograft repair of a symptomatic 6-cm type II TAAA. The t-Branch thoracoabdominal stent graft was positioned without difficulty.

Purpose: Description of physician-modified endograft technique and its advantages using the TREO stent graft system.
Technique: After partial back-table deployment of the TREO endograft, fenestrations are created using a scalpel and reinforced with a double snare loop and running suture. The distance between the Z-shaped stents of the TREO main body of almost 20 mm allows for more flexible placement of multiple fenestrations and easier and faster re-sheathing.
