An 84-year-old Case of Abdominal Aortic Aneurysm with Three-vessel Coronary Artery Disease / 日本心臓血管外科学会雑誌

ABSTRACT

An 80-year-old male patient had complained of left abdominal pain since 1990, and an abdominal aortic aneurysm (AAA) 5.3cm in diameter was diagnosed by computed tomography (CT). The patient was NYHA class III with complaints of chest pain during exercise. Coronary arteriography showed that he had three-vessel disease. At that time, aneurysmectomy was not anticipated due to his age and because the AAA showed no tendency to enlarge. However, in October 1993, CT showed that the AAA rapidly enlarged to 6.8cm in diameter. Due to the greater risk of rupture of the AAA, aneurysmectomy was considered necessary. The operative mortality associated with aneurysmectomy in patients with coronary artery disease (CAD) is higher than that in patients without CAD. Therefore, coronary artery bypass grafting (CABG) was indicated prior to aneurysmectomy. The patient underwent CABG (two vessels) in December 1993, and aneurysmectomy was successfully performed in February 1994. He was discharged uneventfully 17 days after the operation.
