Complication of venous thrombosis of the lower extremities with pulmonary embolism

We studied the relationship between the complication of the pulmonary embolism and the localization of the venous thrombus in the lower extremities using Tc-99m macroaggregated albumin (MAA) venography. Tc-99m MAA venography clearly demonstrated most of the deep and superficial veins from the leg to the pelvis and the abdomen. The incidence of venous thrombosis was highest in the pelvic veins (28.8%), and second in the superficial leg veins (10.9%). The complication of pulmonary embolism was highest in the pelvic venous thrombosis (20.4%), and second in the femoral venous thrombosis (16.0%). (author)
