Endovascular stent repair of celiac arterial aneurysm

The aim of this study was to evaluate the safety and clinical effectiveness of endovascular stent repair of celiac arterial aneurysm (CAA). From January 2015 to December 2018, 11 patients (7 males, 4 females with a mean age of 52.2 ± 7.9 years) underwent endovascular stent repair of CAA in our center. A covered stent was used to occlude the CAA neck. Follow-up was performed 2 weeks and 1, 3, 6, and 12 months following surgery and yearly thereafter. Rates of technical success, treatment-related complications, and long-term outcome were analyzed. Each patient was placed with 1 stent for repair of CAA. Stent was placed in the celiac and common hepatic arteries for 10 patients and was placed in the celiac artery for 1 patient. The duration of the procedure ranged from 50 to 75 minutes (mean 63.2 ± 7.2 minutes). The rate of technical success of the endovascular stent repair was 100%. No patient experienced CAA rupture or instant endoleak during or after stent insertion. Abdominal pain was relieved progressively after stent insertion. All patients were followed-up for 6 to 48 months (mean 22.4 ± 10.8 months). All patients were alive during the follow-up. No endoleaks were experienced during follow-up with 100% stent patency rate. No patient suffered splenic, hepatic, or bowel infarction during follow-up. Endovascular stent repair is a safe, simple, and effective treatment for patients with CAA.
