We describe two cases of venous reconstruction after radial artery (RA) harvesting for coronary artery bypass grafting (CABG). Patient 1, a 70-year-old man who underwent CABG 16 years earlier, presented with acute posterolateral myocardial infarction caused by total occlusion of the saphenous vein graft (SVG). RA grafting was considered ideal, but he had bilateral hypoplastic ulnar arteries. Venous reconstruction with RA harvesting using SVG was performed, and surgery was successful. Patient 2, a 57-year-old-man with chronic renal failure caused by polycystic kidney disease, presented with angina pectoris. Off-pump CABG was recommended. We used a right internal thoracic artery and the RA as an I-composite graft. However, RA preservation was essential for future hemodialysis. The RA was harvested and reconstructed as described for patient 1. Ischemia had not developed in the hands and forearms as of 5 years after the surgery. We believe that the method may be an alternative graft choice in CABG.
我们描述了两例在冠状动脉旁路移植术(CABG)中取桡动脉(RA)后进行静脉重建的病例。病例1为一名70岁男性,16年前接受了CABG,因大隐静脉移植血管(SVG)完全闭塞导致急性后外侧心肌梗死。桡动脉移植被认为是理想的选择,但他双侧尺动脉发育不良。于是采用SVG取桡动脉进行静脉重建,手术成功。病例2为一名57岁男性,因多囊肾病导致慢性肾衰竭,出现心绞痛。建议进行非体外循环CABG。我们使用右胸廓内动脉和桡动脉作为I型复合移植物。然而,保留桡动脉对未来的血液透析至关重要。按照病例1的方法取桡动脉并进行重建。截至术后5年,手部和前臂未出现缺血情况。我们认为该方法可能是CABG中一种可供选择的移植物。
