A Case of Multiple Aneurysms due to Aortitis Syndrome / 日本心臓血管外科学会雑誌

ABSTRACT

A 51-year-old man underwent arch replacement for a thoracic aortic succular aneurysm in December 1996. The pathological examination indicated aortitis to be the cause of the aneurysm. At that time we did not surgically treat the abdominal aortic aneurysm (AAA) which was only 32mm in diameter. Sixteen months after the first operation, he complained of a pulsatile tumor in his left leg. Angiography revealed an aneurysm of the left superficial femoral artery. The artery distal to the aneurysm was occluded, and the left popliteal artery received collateral blood flow from the deep femoral artery. The size of the AAA increased to 48mm, an indication of repair. Aneurysmectomy of the left superficial femoral artery and replacement of the abdominal aorta were performed simultaneously. The operative findings showed that the aneurysm of the left superficial femoral artery had been ruptured and formed a pseudoaneurysm. The pathological findings demonstrated both aneurysm aortitis. After the second operation, he was given steroid therapy to control the inflammatory reaction and he has been well for one year.
