RESUMO
PURPOSE: To determine the feasibility, safety, and long-term outcome of stent-graft insertion for endovascular repair of celiac artery aneurysm (CAA). MATERIALS AND METHODS: From January 2010 to April 2015, 10 patients (three men and seven women; mean age, 51.6 y ± 12.1; age range, 39-81 y) with CAAs underwent endovascular repair via stent-graft insertion in a single center. During treatment, the stent graft was placed at the celiac and common hepatic arteries. Standard follow-up protocol included abdominal CT angiography and clinical examinations at 1, 3, 6, and 12 months and annually thereafter. Follow-up was performed every 2-3 months via telephone for the duration of the follow-up period to confirm patients' general condition. Data on patient characteristics, technical success, procedure-related complications, and follow-up were collected and analyzed retrospectively. RESULTS: CAA was successfully sealed by the stent graft in all patients. The common hepatic artery was patent after stent insertion in all patients, and no procedure-related complication occurred. All patients were followed up for 1-64 months (mean, 19.3 mo ± 18.9). Abdominal CT angiography demonstrated no endoleak, stent obstruction, or splenic infarction during follow-up. All patients experienced CAA shrinkage with formation of thrombi or increase in the quantity of thrombi in the CAA sac. CONCLUSIONS: Stent-graft insertion is a safe and effective method for endovascular repair of CAA.
