ABSTRACT
We report an extremely rare case of early disruption of a woven Dacron graft by the mechanical force of the lumbar vertebral body after a thoracoabdominal aortic aneurysm repair. A 75-year-old man with thoracoabdominal aortic aneurysm of Crawford type III underwent replacement of the thoracoabdominal aorta using a Gelweave thoracoabdominal graft (Vascutek) and a Gelweave bifurcate graft (Vascutek). His postoperative course was uneventful and discharged on postoperative day 20. On the 22nd postoperative day, he was re-hospitalized with low back pain. Computed tomography scanning showed a massive hematoma around the region of the graft-to-graft anastomosis. He underwent an emergency operation. At laparotomy, the Gelweave thoracoabdominal graft had a 2-mm hole which had been caused by the mechanical force of lumbar vertebral body, which was not related to the anastomosis. The graft was repaired with a 4-0 polypropylene buttress suture and a new prosthesis graft was used to wrap around the disrupted graft.
ABSTRACT
We describe a 52 year old woman who had an aneurysm involving the common hepatic artery directly originating from the aorta. It was successfully treated by aneurysmectomy without needing the arterial reconstruction. An aneurysm of the common hepatic artery that has an anomalous origin from the aorta is very rare and only 4 cases including the present case were reported in Japanese literature on our survey. The features and management of hepatic aneurysm are discussed.
