The Vieussens' artery is an anastomotic communication between the conus branch of the right coronary artery and the left anterior descending (LAD). Vieussens' ring is so named because it circles around the great vessels in the form of a partial ring. The course of the artery can be best understood in 2 orthogonal views. In the left oblique view, the artery appears coursing upward to the left. In the right oblique view, it courses anteriorly across the right ventricular outflow tract. The clinical significance of Vieussens' arterial ring lies in it being a major source of collateral blood flow to an occluded LAD. The presence of this large collateral may explain preserved ventricular function in our patient, despite severe triple-vessel disease.
维厄桑动脉是右冠状动脉圆锥支与左前降支之间的吻合支交通。维厄桑环之所以得名，是因为它呈部分环的形式环绕大血管。动脉的走行可以在两个正交视图中得到最好的理解。在左斜视图中，动脉向上向左走行。在右斜视图中，它向前穿过右心室流出道。维厄桑动脉环的临床意义在于它是闭塞的左前降支侧支血流的主要来源。这种大的侧支的存在可以解释尽管存在严重的三血管病变，但我们的患者心室功能仍保持完好。
