Surgical repair of a giant coronary artery aneurysm

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Vascular Medicine

Background:

• Giant coronary artery aneurysms (GCAAs) are rare cardiovascular anomalies.
• Type B aortic dissection is a serious condition affecting the aorta.
• Coexistence of GCAA and aortic dissection presents unique management challenges.

Observation:

• A 67-year-old male presented with a giant aneurysm of the circumflex artery (4.8 × 4.2 × 7.2 cm).
• The patient had a recent diagnosis of type B aortic dissection.
• The aneurysm had a dual-ostium distal end.

Findings:

• Successful surgical management of the giant coronary aneurysm was achieved.
• The surgical technique involved proximal end ligation of the aneurysm.
• A bypass using a reverse saphenous vein graft was performed for the distal end.

Implications:

• This case demonstrates a viable surgical approach for complex GCAAs, even in the presence of aortic dissection.
• The findings suggest that surgical intervention can be effective for large coronary aneurysms.
• Successful management may improve patient outcomes and reduce the risk of complications associated with GCAAs.
