title: Coagulation abnormalities in idiopathic portal venous thrombosis.
abstract: BACKGROUND
  Portal vein thrombosis, usually idiopathic, is the cause of portal hypertension in 46% of Indian patients, who present with a variceal bleed. The presence of lupus anticoagulant (LA) and antithrombin III deficiency have been reported to be associated with an increased tendency to venous thrombosis.
  
  
  RESULTS
  We studied 30 patients with portal venous thrombosis diagnosed by ultrasound. Two patients were positive for a lupus anticoagulant and both had very prolonged partial thromboplastin time with kaolin. None of the patients had antithrombin III deficiency.
