[A case of inferior vena cava thrombosis associated with cholelithiasis demonstrated by ultrasonic examination].

A case of a 44 year old female with inferior vena cava thrombosis associated with cholelithiasis was reported. The patient had chest and back pain due to pulmonary embolism. Ultrasonic examination showed stone echoes in the gallbladder and thrombus echoes in the inferior vena cava (IVC) at the height from renal veins to bifurcation of iliac veins, but iliofemoral thrombosis was not found by RI angiography and venography. Anticoagulant and urokinase were administered, then pulmonary embolus disappeared and IVC thrombus reduced. IVC thrombus was removed by incision of IVC. Thrombus was white thrombus. Etiology of thrombus was not clear. IVC ligation or plication for prevention of pulmonary emboli was not carried out. Etiology, diagnosis and treatment of IVC thrombosis were also discussed.
