Coronary collaterals are important in evaluations made for bypass coronary artery surgery because of their role in the preservation of myocardial function. This paper attempts to define collaterals, explain how they develop, and describe what role they play in the normal heart. It presents a model of the different types of coronary collaterals, emphasizing the intracoronary and intercoronary anastomoses. The controversial role of the function of collaterals in coronary artery disease is discussed extensively, with special attention given to more recent angiographic in vivo studies. Recent investigations indicate that collaterals may limit the size of myocardial infarction as they help to preserve myocardial functions; they assist in the evaluation of both runoff and function for patients being considered for bypass surgery. As more is learned about collaterals, undoubtedly we shall gain a greater appreciation of their significance.
由于冠状动脉侧支循环在心肌功能保护中发挥的作用，其在冠状动脉搭桥手术评估中具有重要意义。本文试图对侧支循环进行定义，解释其形成方式，并描述其在正常心脏中的作用。文中提出了不同类型冠状动脉侧支循环的模型，重点强调了冠状动脉内和冠状动脉间的吻合。本文广泛讨论了侧支循环功能在冠状动脉疾病中存在争议的作用，并特别关注了最近的体内血管造影研究。最近的研究表明，侧支循环有助于保护心肌功能，从而可能限制心肌梗死的范围；它们有助于评估考虑接受搭桥手术患者的血流灌注和心脏功能。随着对侧支循环了解的不断深入，无疑我们将更深刻地认识到其重要性。
