title: Budd-Chiari syndrome complicating restorative proctocolectomy for ulcerative colitis: report of a case.
abstract: OBJECTIVE
  This is a case of hepatic vein thrombosis presenting in a delayed fashion after proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis. Search for a causative thrombotic condition resulted in the diagnosis of polycythemia vera, a myeloproliferative disorder associated with hypercoagulability. The polycythemia was masked by an iron deficiency associated with the ulcerative colitis.
  
  
  METHODS
  The history, physical, diagnostic modalities, and treatment for this patient are described, and the literature of Budd-Chiari syndrome associated with ulcerative colitis is reviewed.
  
  
  RESULTS
  Six cases of Budd-Chiari syndrome in the setting of ulcerative colitis are reported in the literature from 1945 to 1997.
  
  
  CONCLUSIONS
  Hepatic vein thrombosis is a rare complication of ulcerative colitis. The diagnosis of Budd-Chiari syndrome demands a thorough search for a hematologic condition predisposing to thrombosis. Our patient had a myeloproliferative disorder, polycythemia vera, that is associated with a hypercoagulable state. The disorder was masked by an iron deficiency associated with the ulcerative colitis. Recognition of the entity will permit successful treatment.
