Endovascular Repair of Complex Aortic Aneurysms

Background: Surgery for complex aortic aneurysms (thoraco-abdardinal, juxtarenal and pseudoaneurysms) is associated with a high morbidity and mortality rate. Branched and fene-strated stent grafts constitute a new technology intended as an alternative treatment for this disease. Objectives: To describe a Single-center experience with fenestrated and branched endografts for the treatment of complex aortic aneurysms. Methods: We reviewed all cases of complex aortic aneurysms treated with,branched orfenestrated devices in our center. Data collected included device specifics, perioperative morbidity and Mortality, re-intervention rates and Mid-term results. Results: Between 2007 and 2012 nine patients were treated with branched and fenestrated stent grafts. Mean age was 73 years. Mean aneurysm size, was 63 mm. Perioperative mortality was 22% (2/9). During the follow-up, re-interventions were required In 3 patients (33%). of 34 visceral artery branches 33 remained patent, resulting in a,patency rate of expansion was seen in a single patient due to a large endoleak. No late aneurysm related deaths occurred. Conclusions: Branched and fenestrated stent grafts are feasible. and. relatively safe alternatives for the treatment of complex aortic aneurysms involving the visceral segment Further research is needed to determine the long term of this rift technology.
