Preduodenal portal vein (PDPV) is a rare congenital vascular malformation, which was first described by Knight in 1921 as an anomalous vein that lies in front of the duodenum, common bile duct, and hepatic artery instead of beneath them. This abnormal position may result in congenital duodenal obstruction and puts it in danger during operations around this region. PDPV is typically associated with other congenital anomalies, mainly intraabdominal and cardiac ones. The surgical management is usually determined intraoperatively based on evidence that the PDPV is the real cause of obstruction. We report two cases of PDPV each with a different presentation and management approach.
十二指肠前门静脉（PDPV）是一种罕见的先天性血管畸形，1921年由奈特首次描述为一条异常静脉，它位于十二指肠、胆总管和肝动脉前方而非其下方。这种异常位置可能导致先天性十二指肠梗阻，并在该区域周围的手术中使其处于危险之中。PDPV通常与其他先天性异常相关，主要是腹腔内和心脏方面的异常。手术管理通常在术中根据PDPV是梗阻真正原因的证据来确定。我们报告两例PDPV病例，每个病例都有不同的表现和处理方法。
