Abstract
Renal artery aneurysm is gradually increasingly owing to the recent development of imaging diagnostic techniques and is often identified accidentally through computed tomography (CT) and ultrasonographic examinations. Endovascular treatment (EVT) and surgery are treatment options. Here, we report two cases of surgical treatment for renal artery aneurysm that resulted in satisfactory outcomes. Case 1 : A 70-year-old woman presented with a 24-mm (diameter) saccular renal artery aneurysm at the distal renal artery observed on a contrast-enhanced abdominal CT scan, which showed one inflow vessel but two outflow vessels. Surgical treatment was therefore indicated. With use of a renal-protective fluid, the aneurysm was resected and the two outflow arteries were reconstructed. Case 2 : A 76-year-old woman presented with a 17-mm (diameter) saccular renal artery aneurysm at the distal renal artery, with one inflow artery and two outflow arteries, observed on a CT scan. As done in case 1, the aneurysm was resected and the two outflow arteries were reconstructed. The two patients made satisfactory progress and did not exhibit a postoperative decline in renal function. Surgical resection was performed to treat the renal artery aneurysm with two outflow arteries in the two patients. With use of an appropriate renal-protective fluid and reconstruction of all outflow arteries, postoperative deterioration of renal function could be avoided.
