The use of fenestrated devices to treat juxtarenal and group IV TAAA is safe and effective in long-term follow-up. Mortality in this patient population is largely not aortic-related. Devices designed for fenestrated repair of juxtarenal and group IV thoracoabdominal aneurysms within a physician sponsored investigational device exemption have changed over time. Further research is needed to determine the best configuration to treat aneurysms requiring coverage proximal to the celiac artery.

F/B-EVAR is a robust treatment option for patients at increased risk for conventional repair of extensive TAAAs. Technical success and branch patency are excellent, but some patients will require reintervention for branch-related endoleak. Aneurysm extent portends a higher risk of perioperative and long-term morbidity and mortality. Additional efforts are needed to improve outcomes and understand the utility of this treatment option in the general TAAA population.

Abciximab decreases the mortality of diabetic patients to the level of placebo-treated nondiabetic patients. This beneficial effect is noteworthy in those diabetic patients who are also hypertensive and obese and in diabetics undergoing multivessel intervention. Besides its potential role in reducing repeat intervention for stented diabetic patients, abciximab therapy should be strongly considered in diabetic patients undergoing PCI to improve their survival.
