Abstract
Two cases of internal thoracic artery side-branch ligation in patients with recurrent angina after coronary bypass are reported with long-term follow-up. Ligation was performed with clips via a left thoracotomy. Treadmill stress testing after 3 and 4 years did not provoke any myocardial ischemia. These findings suggest that an unligated side-branch can produce a steal phenomenon.
摘要
报告了2例冠状动脉搭桥术后复发性心绞痛患者进行胸廓内动脉侧支结扎并长期随访的病例。通过左胸切口用夹子进行结扎。3年和4年后的平板运动试验未诱发任何心肌缺血。这些发现表明，未结扎的侧支可产生窃血现象。
