The prepancreatic postduodenal portal vein (PPPV) is an unusual anomaly, having been reported in only 11 cases including ours. Although its incidence is rare, this anomaly can cause intraoperative complications such as hemorrhage from the abnormal vein. Radiologists therefore need to be aware of this anomaly and, when identifi ed, report it to surgeons before surgery. Here we report two cases of PPPV and present a new hypothesis for development of the portal venous system.
胰前十二指肠后门静脉（PPPV）是一种罕见的异常，包括我们的病例在内，全球仅报道过 11 例。尽管其发病率较低，但这种异常可能导致术中并发症，如异常静脉出血。因此，放射科医生需要意识到这种异常，并在术前向外科医生报告。在此，我们报告两例 PPPV 病例，并提出门静脉系统发育的新假说。
