The existence of a chest wall "steal" of blood away from the myocardium through patent internal mammary artery branches has been hypothesized as a cause of recurrent angina pectoris after coronary artery bypass grafting. Although some authors believe that such a steal is physiologically impossible because coronary flow occurs in diastole and chest wall flow in systole, we recently documented ischemia in the left anterior descending coronary artery distribution before embolization of a large left internal mammary artery first intercostal branch that had been left intact at the time of operation. After embolization of the branch, clinical and objective evidence of ischemia resolved.

假设存在胸壁通过未闭的乳内动脉分支从心肌 “窃取” 血液,这是冠状动脉旁路移植术后再发心绞痛的原因。尽管一些作者认为这种偷窃在生理上是不可能的,因为冠状动脉血流发生在舒张期,胸壁血流发生在收缩期,但我们最近记录了左前降支在栓塞大的左乳内动脉第一肋间分支之前的缺血。在手术时保持完整。分支栓塞后,缺血的临床和客观证据得以解决。
