Objective: To investigate the treatment method for true aneurysm of splenic artery adjacent to celiac trunk. Methods: The clinical data of 7 patients with true aneurysm of splenic artery adjacent to the celiac trunk admitted from 2000 January to 2012 June were retrospectively analyzed. Results: All patients were diagnosed by color ultrasonography, CT and angiographic examinations before operation, and underwent surgical treatment under general anesthesia. Of the patients, 4 cases underwent aneurysmectomy plus infrarenal abdominal aortosplenic artery bypass using a vascular prosthesis, 2 cases underwent aneurysmectomy plus splenectomy, and one case underwent resection of multiple small aneurysms and splenic artery ligation plus splenectomy. All patients recovered and were discharged from the hospital 10–14 d after operation. During the 2- to 14-year follow-up, 5 cases survived; 2 cases died, of which one case died of acute myocardial infarction 2 years after aortosplenic artery bypass surgery and one case died of acute cerebral hemorrhage 5 years after aneurysmal resection and splenectomy. Among the 5 survival patents, of the 3 cases that underwent aortosplenic artery bypass surgery, the anastomotic site in one case gradually became narrowed beginning from 2 years postoperatively and was completely occluded at 6 years postoperatively, but no splenic infarction, anastomotic stricture or false aneurysm was found in the other 2 cases; 2 patients received aneurysmectomy plus splenectomy. Conclusion: Aneurysmectomy combined with splenic artery reconstruction is an effective treatment method for true aneurysms of splenic artery adjacent to the celiac artery.
