There is renewed interest in the use of the radial artery as a conduit for coronary artery bypass surgery. The radial artery is, however, a very muscular artery, prone to vasospasm. Milrinone, a potent vasodilator, has demonstrated vasodilatory properties superior to those of papaverine. In this report, we describe our technique of radial artery harvesting and the adjunctive use of intraluminal milrinone as a vasodilator in the preparation of this conduit for coronary artery bypass grafting. We have used these techniques in 25 patients who have undergone coronary artery bypass grafting using the radial artery. No hand ischemic complications have been observed in this group. Intraluminal milrinone appears to dilate and relax the radial artery, rendering this large conduit spasm free and very easy to use. We recommend the skeletonization technique for radial artery harvesting and the use of intraluminal milrinone as a radial artery vasodilator in routine myocardial revascularization.
人们对将桡动脉用作冠状动脉搭桥手术的血管 conduit 的兴趣再度兴起。然而，桡动脉是一条肌肉非常丰富的动脉，容易发生血管痉挛。米力农是一种强效血管扩张剂，已证明其血管扩张特性优于罂粟碱。在本报告中，我们描述了桡动脉获取技术以及腔内使用米力农作为血管扩张剂在制备该血管 conduit 用于冠状动脉搭桥术中的辅助应用。我们已将这些技术应用于 25 例接受了使用桡动脉的冠状动脉搭桥手术的患者。该组未观察到手部缺血并发症。腔内米力农似乎能扩张并松弛桡动脉，使这条大血管 conduit 无痉挛且非常易于使用。我们推荐在常规心肌血运重建中采用骨骼化技术获取桡动脉并使用腔内米力农作为桡动脉血管扩张剂。
