Surgically Treated Renal Artery Aneurysm / 대한혈관외과학회지

ABSTRACT

Renal artery aneurysm is a rare disease that can be found on routine examination. With development of interventional radiology, most cases of renal artery aneurysm had been treated with coil and stents. However, the use of coil and stents has a higher morbidity than surgical treatment and is anatomically restricted. A 62-year-old female had a scheduled visit the hospital to evaluate ongoing hypertension and upper abdominal pain. On computed tomography scan, a small aneurysmal dilatation was detected in the mid-portion of the left renal artery. We tried to correct this problem using radiologic intervention. However, the attempt had to be aborted because of the anatomical complexity of aneurysm location. During the operation, the aneurysmal sac was found to be located between the inferior border of pancreas and the upper border of the renal vein. After resection of the aneurysm, both ends of the artery were anastomosed directly without using any patches. The patient was discharged without any complications related to the operation. Radiologic intervention is now replacing traditional vascular surgery. However, there are limitations in conditions of anatomical difficulty and complexity.
