Preduodenal or precholedochal veins are rare developmental anomalies of considerable surgical importance. Injury to these structures because of failure to recognize them during operations for unrelated diseases may result in thrombosis or hemorrhage. We recently encountered this anomaly twice, once in a newborn infant with duodenal obstruction and once in a 54-year-old woman undergoing cholecystectomy. The preduodenal vein was not the primary cause of obstruction in the infant, but injury to the previously unrecognized percholedochal vein in the woman resulted in a considerable loss of blood. Besides describing and illustrating these two cases, we also discuss the anatomy and the embryology of these structures and briefly review the patterns of 44 previously reported cases that we found.
十二指肠前或胆总管前静脉是罕见的发育异常，具有重要的外科意义。在因其他无关疾病进行手术时，若未识别出这些结构而导致损伤，可能会引发血栓形成或出血。我们最近两次遇到这种异常情况，一次是在一名患有十二指肠梗阻的新生儿中，另一次是在一名接受胆囊切除术的54岁女性中。十二指肠前静脉并非婴儿梗阻的主要原因，但该女性中先前未被识别的胆总管前静脉受损导致了大量失血。除了描述和展示这两个病例外，我们还讨论了这些结构的解剖学和胚胎学，并简要回顾了我们找到的44例先前报道病例的情况。
