Abstract
A 40-year-old man was referred for evaluation of hypertension. Abdominal computed tomography (CT) showed a 24×18 mm splenic artery aneurysm near the splenic hilum. Because of a risk of rupture, spleen-preserving laparoscopic aneurysmectomy of the splenic artery was planned. An interventional radiology approach was another option, but the diameter of the splenic artery was too large to treat with coiling. Prior to the operation, enhanced CT angiography was performed to determine the blood flow in the spleen after ligation of the splenic artery. The proximal axis and distal upper and lower branches of the splenic artery were clipped, and the aneurysm was excised. The postoperative course was uneventful, and the patient was discharged on postoperative day 7. Postoperative enhanced CT angiography showed adequate blood flow to the spleen through collateral flow. This is an optional operative method for an aneurysm of the splenic artery.
