Multiple coronary artery aneurysms combined with abdominal aortic aneurysm.

Coronary artery aneurysm (CAA) is defined as coronary dilatation which exceeds the diameter of a normal adjacent segment or the diameter of the patients's largest coronary vessel by as much as 1.5 times. It is an uncommon pathology with a frequency of 1-4% in routine autopsies or coronary angiographies. Atherosclerosis plays an important role in the development of CAA, and it may be a predominant cause in the majority of patients. However, the timing of surgical intervention and the treatment options for CAA are still controversial. In this report, we present a patient who had multiple CAAs of all main coronary arteries and abdominal aortic aneurysm. Different treatment modalities and indications are also discussed.
