Percutaneous transluminal coronary angioplasty is an effective technique for the treatment of selected patients with ischemic heart disease due to coronary artery stenosis. Successful angioplasty in saphenous vein bypass grafts has been documented, but little experience has been reported using angioplasty in internal mammary artery to coronary artery bypass grafts. Nine of ten patients with stenosis in the internal mammary artery to coronary artery anastomosis or in the coronary vessel distal to the anastomosis site were successfully treated with angioplasty. One patient developed restenosis 1 month after the procedure, and a repeat angioplasty was successful. In one patient, the balloon catheter could not be advanced through the left internal mammary artery to the stenosis site. Technical features of internal mammary artery angioplasty are discussed, including the use of specially designed guiding wires, guiding catheters, and balloon catheters that facilitate angioplasty involving internal mammary arteries from the femoral approach.
经皮腔内冠状动脉成形术是治疗因冠状动脉狭窄所致缺血性心脏病特定患者的有效技术。已证实隐静脉旁路移植血管的血管成形术成功，但使用血管成形术治疗胸廓内动脉至冠状动脉旁路移植血管的经验报道较少。十例胸廓内动脉至冠状动脉吻合口或吻合口远端冠状动脉血管狭窄患者中，九例经血管成形术成功治疗。一例患者术后1个月出现再狭窄，再次血管成形术成功。一例患者球囊导管无法经左胸廓内动脉推进至狭窄部位。本文讨论了胸廓内动脉血管成形术的技术特点，包括使用专门设计的导丝、导管和球囊导管，这些有助于从股动脉途径对胸廓内动脉进行血管成形术。
