During the routine review of control follow-up cinéangiograms taken of patients after aorto-coronary bypass grafting, the authors noted a number of vein graft stenoses of varying severity. All stenoses were in the segment of vein away from the aortic or coronary anastomoses, but were clearly at the site of a steel clip used to occlude side branches during preparation of the vein graft. The incidence was too high to be related to chance, and in some cases the intrusion of the clip upon the lumen was obvious. Suggestions are made to eliminate the occurrence of this iatrogenic stenosis.
在对接受主动脉冠状动脉搭桥术的患者进行术后常规对照随访血管造影片复查时，作者们注意到了一些不同严重程度的静脉移植物狭窄情况。所有狭窄均位于静脉远离主动脉或冠状动脉吻合口的节段，但明显位于在静脉移植物制备过程中用于闭塞侧支的金属夹所在部位。其发生率过高，不可能是偶然现象，而且在某些病例中，金属夹向管腔内的侵入很明显。文中提出了消除这种医源性狭窄发生的建议。
