An increasing number of patients with advanced coronary artery disease and diffusely complex atherosclerotic lesions are referred for coronary artery bypass surgery (CABG). Under these circumstances, complete myocardial revascularization with an adequate distal runoff can only be achieved by extensive manual endarterectomy and a reconstructive procedure prior to conduit placement. Because of the numerous septal and diagonal branches of the left anterior descending artery (LAD), an extended and meticulous endarterectomy is warranted. Placement of the internal mammary artery (IMA) on such a widely opened vessel requires reconstruction with a vein patch and the IMA. A modified technique of extended manual endarterectomy, distal vein patch, and proximal IMA reconstruction and revascularization is described. This technique was used in six patients between October 1990 and December 1992 with 100% early survival. This technique is less time consuming and more importantly allows for a direct artery-to-artery anastomosis with the potential for a better long-term patency.
越来越多患有晚期冠状动脉疾病和弥漫性复杂动脉粥样硬化病变的患者被转诊接受冠状动脉旁路移植术(CABG)。在这种情况下,只有通过广泛的手工内膜切除术和在放置移植血管之前进行重建手术,才能实现充分的远端血流灌注下的完全心肌血运重建。由于左前降支动脉(LAD)有众多的间隔支和对角支,因此需要进行广泛而细致的内膜切除术。将乳内动脉(IMA)置于如此广泛开放的血管上需要用静脉补片和IMA进行重建。本文描述了一种改良的广泛手工内膜切除术、远端静脉补片、近端IMA重建和血运重建技术。1990年10月至1992年12月期间,该技术应用于6例患者,早期生存率达100%。该技术耗时较少,更重要的是可以进行直接的动脉对动脉吻合,有可能获得更好的长期通畅率。
