Abstract:
This brief report describes 3 patients with infected extrahepatic splanchnic venous stents or stent grafts. These devices had been placed to treat prehepatic portal hypertension 4 wk, 3 mo, and 31 mo, respectively, before readmission for fever. Blood cultures and fluorine-18 fludeoxyglucose positron emission tomography/CT were positive in all. With systemic antibiotic treatment, 2 patients showed a clinical recovery. In the third patient, antibiotic treatment failed. Therefore, the infected stent graft was surgically removed and a splenorenal shunt was created. No recurrent splanchnic venous infection was observed in these 3 patients.
