Endovascular Repair of Celiac Artery Aneurysm with the Use of Stent Grafts.

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.
