veine porte preduodenale: Apropos d'un cas

ABSTRACT

The authors report a case of a 53-year-old woman that was suspected as having a preduodenal portal vein in echoendoscopy. The diagnosis was confirmed at laparotomy performed for biliary lithiasis. No surgical procedure was performed because there was no evidence of duodenal obstruction by this preduodenal portal vein. The preduodenal portal vein is an exceptional congenital anomaly that must be considered as a rare cause of duodenal obstruction. The tomodensitometry and possibly the echoendoscopy allow the diagnosis. Many other congenital anomalies such as a duodenal atresia can be associated and must always be searched
