Operative treatment of celiac trunk aneurysms has traditionally involved open repair using simple ligation, interposition graft, resection, and direct repair or antegrade bypass from the aorta; recently, endovascular techniques have been proposed in selected cases. We report a 60-year-old man presenting with a celiac trunk aneurysm that we treated with a new multilayer stent with the aim of preserving the parent vessels arising from the aneurysm. Computed tomography angiography at the 12-month follow-up visit confirmed the patency of the stents, the complete thrombosis of the sac without impairment of the main branches, and the regular perfusion of the liver and spleen.

Case Reports
Primary aortoenteric fistula following endovascular aortic repair due to type II endoleak.
An 84-year-old female was lost to follow-up after endovascular aneurysm repair at another hospital with known type II endoleak. She later presented with presyncope and hematemesis. A referral center esophagogastroduodenoscopy showed possible duodenal diverticulum. ⋯ At our center, she underwent stent graft explantation and axillofemoral reconstruction for a primary aortoenteric fistula. She was discharged and is doing well 5 months postoperatively. A high degree of suspicion for aortoenteric fistula is imperative in any patient with upper gastrointestinal hemorrhage after open or endovascular abdominal aortic aneurysm repair.

A consequence of endovascular aneurysm repair (EVAR) of anatomically straightforward infrarenal abdominal aortic aneurysm repair cohort (AAA) is that open aneurysm repair is more commonly performed for complex anatomy. Complex aneurysm repair with visceral vessel involvement (CAA) or combined aneurysm repair and visceral vessel reconstruction (VVR) has traditionally been considered to increase morbidity and mortality compared with repair of infrarenal AAA. This study evaluated contemporary outcomes of open abdominal aneurysm surgery, including AAA, CAA, and VVR using the National Surgical Quality Improvement Program (NSQIP) database. ⋯ In contemporary practice the migration of open repair to increasingly complex cases has been achieved with 30-day mortality essentially equivalent to open repair of infrarenal AAA. Patients who require VVR do sustain increased complications, in particular renal failure. These data also emphasize the importance of baseline renal insufficiency in clinical decision making. CAA and VVR are associated with increased morbidity in comparison to AAA repair; however, both procedures can be safely performed in patients without increased risk of operative mortality.

We present a 66-year-old man with a 5.7-cm saccular descending thoracic aortic aneurysm and a smaller 4.6-cm aneurysm just proximal to the celiac artery. The patient was judged to be too risky for open surgical repair because of poor anatomy and health. Previous stenting of the iliac arteries for a kinked aortoiliac open graft precluded conventional endovascular aneurysm repair. The descending thoracic aorta was successfully repaired using endovascular methods with a standard Talent (Medtronic, Los Angeles, Calif) thoracic proximal main stent graft, which was reverse-loaded onto the delivery device and delivered antegrade through the right axillary artery.
