A left circumaortic renal vein was found in 11% of 74 left renal venograms, an incidence similar to that at autopsy. Cavography proved to be an unsatisfactory method of demonstrating the renal veins. Prior knowledge of a venous ring is important when blood samples from the adrenal or renal veins are to be collected. When caval interruption is planned, a circumaortic venous ring may provide a fully developed collateral pathway immediately after surgery if the procedure is planned without awareness of its presence.
在74例左肾静脉造影中，11%发现有左环主动脉肾静脉，其发生率与尸检时相似。腔静脉造影被证明是一种显示肾静脉的不理想方法。在采集肾上腺或肾静脉血样时，事先了解静脉环很重要。当计划进行腔静脉阻断时，如果在手术规划时未意识到其存在，那么环主动脉静脉环可能在手术后立即提供一条充分发育的侧支通路。
