Аннотация
BACKGROUND: Saphenous vein graft (SVG) aneurysms are a rare but potentially life-threatening complication after coronary artery bypass grafting, with an estimated incidence of 0.07%. Presentations range from incidental imaging findings to severe complications, including rupture, myocardial infarction, or compression of mediastinal structures.
CASE SUMMARY: A 65-year-old man with prior 3-vessel coronary artery bypass grafting presented with progressively worsening substernal chest pressure. Coronary angiography and computed tomography angiography identified a 71 × 45-mm saccular pseudoaneurysm of the SVG. Following heart team discussion, the patient underwent intravascular ultrasound-guided percutaneous coronary intervention with sequential covered stent deployment, resulting in complete exclusion of the pseudoaneurysm.
DISCUSSION: Optimal management remains uncertain because of limited clinical data. This case emphasizes the feasibility of intravascular ultrasound-guided covered stent placement; to our knowledge, this is the largest reported de novo SVG pseudoaneurysm treated with this approach.
TAKE-HOME MESSAGE: In selected patients, covered stent placement offers a safe, minimally invasive alternative to surgery while preserving graft patency.
