A Case of Celiac Artery Aneurysm with Type IIIb Aortic Dissection / 日本心臓血管外科学会雑誌

ABSTRACT

Celiac artery aneurysm (CAA) is very rare. We report a case of CAA with type IIIb aortic dissection (DA) which was treated surgically. A 60-year-old man who had an abnormal enlargement of the aorta on abdominal ultrasonography was admitted to our hospital. Angiography and CT scan revealed CAA with type IIIb DA. His general condition was stable and surgery was performed electively. The CAA was exposed through a median laparotomy. It was found to be about 3cm in diameter. As vascular reconstruction seemed difficult and the proper hepatic artery showed good pulsation after clamping the common hepatic artery, we decided to perform celiac artery aneurysmectomy without vascular reconstruction. Except for transient liver dysfunction, there was no other complication and he was discharged on the 24th postoperative day. During surgery for CAA, when collateral perfusion from the SMA to the liver is adequate, it seems that vascular reconstruction is not always necessary as shown by this case.
