Coronary-to-coronary bypass grafting in aortoarteritis: a case report

Area of Science:

• Cardiology
• Immunology
• Vascular Medicine

Background:

• Takayasu's arteritis is a rare idiopathic vasculitis impacting the aorta and its major arteries.
• Coronary artery involvement in Takayasu's arteritis, primarily ostial stenosis or occlusion, is infrequent.
• Arterial grafts are often unsuitable in Takayasu's arteritis due to diseased vessels, making saphenous vein grafts a common alternative.

Observation:

• A young female patient presented with Takayasu's arteritis and ostial left main stenosis.
• The patient underwent a surgical procedure utilizing a saphenous vein graft (SVG).
• The graft was a right coronary artery to left anterior descending artery bypass.

Findings:

• The patient was treated with immunosuppression and corticosteroids.
• During a 7-year follow-up period, the patient remained asymptomatic.
• The saphenous vein graft remained patent throughout the follow-up duration.

Implications:

• This case highlights the successful long-term use of saphenous vein grafts in managing coronary artery stenosis secondary to Takayasu's arteritis.
• It suggests that immunosuppressive therapy combined with surgical intervention can yield favorable outcomes in selected patients.
• The findings support considering SVG bypass as a viable option for complex coronary artery disease in the context of Takayasu's arteritis.
