Budd-Chiari syndrome in a patient with Sjögren's syndrome.

A case of Budd-Chiari syndrome associated with obstruction of the inferior vena cava is reported. The case was complicated by Sjögren's syndrome and chronic thyroiditis. A marked prolongation of activated partial thromboplastin time, due to circulating anticoagulant, was noted. Interrelation of thrombosis of the inferior vena cava, circulating anticoagulant, and Sjögren's syndrome is suggested.
