Pancreatitis-induced extrahepatic portal vein stenosis treated by percutaneous transhepatic stent placement.
One month after onset of an acute biliary pancreatitis, a 75-year-old man developed refractory ascites. Duplex ultrasound and CT scan revealed a focal stenosis of the extrahepatic portal vein as confirmed by transhepatic direct portography. In the same session, this stenosis, responsible for symptomatic prehepatic portal hypertension, was successfully dilated and stented and afterwards a residual pressure gradient of 1 mmHg over the stented segment was measured. One week after the stenting procedure the patient was free of ascites and control physical and biochemical examination one year later is completely normal.
