Tromboflebitis séptica de la vena porta asociada a hipertensión portal reversible / Septic thrombophlebitis of the portal vein associated with reversible portal hypertension

Septic thrombophlebitis of the portal vein is an unusual and serious complication of abdominal infection. We present a patient with thrombophlebitis of the portal vein of unknown origin, suffering from fever, abdominal pain, jaundice, abnormal liver test function and bacteremia related to Bacteroides fragilis. Ultrasonography, with doppler of the portal vein, was performed which showed thrombosis of the portal vein together with signs of portal hypertension. The patient underwent six weeks of antibiotic treatment. The evolution was favourable, the infection was overcome and the portal vein was de-obstructed as a consequence of which the signs of portal hypertension disappeared.
