[Isolated portal vein thrombosis: a rare complication of chronic pancreatitis].

In chronic pancreatitis (CP) portal vein thrombosis (PT) is a less well known complication than splenic vein thrombosis (ST). In the literature up until 1990, 26 cases with PT, have been reported and only 10 cases presented a isolated PT, without ST. We report a new case of isolated PT without ST in a non alcoholic man, who presented with gastroesophageal CP and a cavernomatous transformation of the portal vein. No varices ere detected by endoscopy; because the risk of bleeding was very small, a prophylactic treatment was unnecessary. The pancreas was resected preserving the spleen and cavernomatous transformation or the periportal veins and the patient was cured from his pains. The surgical tactic is an original treatment, particularly when curable pancreatic cancer is suspected.
