Atherosclerosis develops and rapidly progresses in saphenous veins grafts after coronary bypass surgery. In contrast to native coronary artery, percutaneous revascularization does not impede the progression of saphenous vein atherosclerosis and saphenous vein graft failure commonly ensues. The protracted patency of arterial grafts is likely to account for most of the long-term superiority of coronary artery bypass surgery over percutaneous revascularization in patients with complex coronary artery disease. Long-lasting, complete coronary revascularization may be best achieved by combining surgical arterial grafting of diseased coronary arteries to percutaneous revascularization with drug-eluting stents than by the continued use of saphenous vein grafts.
冠状动脉搭桥术后,隐静脉移植物会发生动脉粥样硬化并迅速进展。与天然冠状动脉不同,经皮血管重建术并不能阻止隐静脉动脉粥样硬化的进展,隐静脉移植物通常会随之发生功能衰竭。在患有复杂冠状动脉疾病的患者中,动脉移植物的长期通畅可能是冠状动脉搭桥手术在长期疗效上优于经皮血管重建术的主要原因。对于病变冠状动脉,通过将手术动脉移植与药物洗脱支架经皮血管重建术相结合,可能比持续使用隐静脉移植物更能实现持久、完全的冠状动脉血运重建。
