Abstract

Background: Endovascular treatment is being increasingly used for celiac artery aneurysms (CAAs), but systematic endovascular treatment strategies have not been defined yet. This study intended to investigate the strategies of endovascular management of CAAs according to a single-center experience. Methods: Anatomically, CAAs were classified into two types: Type I CAAs located in the main trunk of celiac artery. Type II CAAs located on the branches of the celiac artery. Type I and Type II CAAs can be further divided into two different subtypes according to fusiform (a) or saccular or (b) morphology: type Ia, type Ib, type IIa, and type IIb. Patient demographics, clinical manifestations, aneurysm characteristics, endovascular intervention procedures, and perioperative and follow-up outcomes were reviewed and analyzed. Results: Between August 2012 and August 2020, 18 consecutive patients (12 men; mean age, 56.8 ± 14.5 years) with CAAs were identified and treated with endovascular procedures. There were seven patients with type Ia, three patients with type Ib, four patients with type IIa, and four patients with type IIb CAAs. One patient died of hemorrhagic shock due to a ruptured aneurysm. Technical success was achieved in 16 patients (88.9%). The mean follow-up period was 51.7 ± 19.4 months. No hepatic or intestinal ischemia or death developed perioperatively or during the follow-up period. No aneurysmal expansion was detected on CTA surveillance, except for one patient who was diagnosed with an endoleak during the follow-up and received reintervention. Conclusions: The endovascular strategy based on the novel classification of CAAs was safe and effective, with a favorable mid-term clinical outcome.
