Rupture of a Right Internal Iliac Artery Aneurysm after Coil Embolization and an Exclusion Operation / 日本心臓血管外科学会雑誌

The patient, a 80-year-old man, had undergone aneurysmectomy and graft replacement of the right external iliac artery aneurysm and coil embolization and exclusion of the right internal iliac artery aneurysm in 2007. Computed tomography showed a rupture of the right internal iliac artery aneurysm in 2010. We performed aneurysmectomy and occlusion of the gluteal artery. The patient had a satisfactory postoperative course.

Three Cases of Ruptured Abdominal Aortic Aneurysm Treated Successfully by the Retroperitoneal Approach / 日本心臓血管外科学会雑誌

The retroperitoneal approach for abdominal aortic aneurysm (AAA) has been used to reduce the risk of postoperative ileus and respiratory failure. This technique is usually used in patients with non-ruptured infrarenal AAA because it has been considered to be more time consuming to approach the aorta than the normal transabdominal approach. However, we may not have sufficient information if the aneurysm is confined to the infrarenal abdominal aorta in a ruptured case. In such a situation, the retroperitoneal approach might be better than the transabdominal approach because an aortic clamp can easily be applied to the suprarenal aorta. We report three cases of ruptured AAA treated successfully by the retroperitoneal approach.

Reoperation following Aortic Valve Replacement Using Tilting Disc Valve Prostheses / 日本心臓血管外科学会雑誌

Fifty-three patients who had received aortic valve replacement (AVR) using tilting disc valve prostheses (Lillehei-Kaster valve, Omniscience valve, Omnicarbon valve), underwent replacement of their aortic valve prostheses over the past 13 years. The indications for reoperation were non-structural opening failure in 35 patients, thrombosed valves, including 2 stuck valves in 8, prosthetic valve endocarditis (PVE) in 7 and perivalvular leakage (PVL) in 3. The interval periods until reoperation for opening failure and thrombosed valve were 112 and 118 months respectively, and for PVE and PVL were 21 and 25 months. There were 7 hospital deaths (13.2%). Surgical results in cases of active PVE with root abscess and stuck valve required emergency operation were significantly worse than these for nonstructural opening failure. Opening failures, which accounted for two-thirds of the indications for reoperation was found to be due to subvalvular pannus formation on minor orifices which hindered the disc from opening properly. It was suggested that reoperation for these types of prosthetic valve should be done before they develop into emergency cases, taking account of these valve-related complications.
