Surgical treatment of coronary artery aneurysms

Introduction Coronary artery aneurysms (CAA) are rare. We present our experience with the surgical treatment of patients with CAAs. Methods Between March 2000 and October 2016, 15 patients with CAA underwent surgery. Results Mean age of patients was 60 ± 16 years and 47% (n = 7) were male. Kawasaki syndrome was present in two (13%) patients and 7% (n = 1) patients had Marfan syndrome. Isolated CAAs were found in 73% (n = 11) and involvement of multiple vessels was present in 27% (n = 4) of patients. Coronary arteries (CA) affected by aneurysms were: 19% (n = 4) left main stem, 33% (n = 7) left anterior descending, 14% (n = 3) left circumflex, and 33% (n = 7) right coronary artery. The majority of patients (93%, n = 14) were operated on pump with a mean cross‐clamp time of 51 ± 23 min. 53% (n = 8) of patients received total arterial CA bypass grafting, while the remaining patients (47%, n = 7) received venous ± internal thoracic artery grafts. Resection/ligation of CAA was performed in 27% (n = 4) of patients. In‐hospital mortality was 0% (n = 0). Follow‐up was complete for 100% of patients and comprised a total of 80 patient‐years. During follow‐up, only one patient (7%) required re‐intervention. Conclusion Surgical treatment of CAA has good short‐ and long‐term results.
