The relationship between isolated soleal vein thrombosis (SVT) and pulmonary hypertension was investigated. The subjects were 64 patients with SVT with suspected pulmonary embolism. SVT was diagnosed by ultrasonography and pulmonary hypertension was diagnosed by ultrasonic cardiography. Pulmonary hypertension was diagnosed in 24% of subjects. Among the 28 patients under recurrent surveillance during the 26.1(±9.3) months, the recurrence of SVT was 36%; the local recurrence was 36%, the proximal propagation was 21%, pulmonary embolism was 7%, and pulmonary hypertension was 18%. It is necessary to take reasonable measures for the local repeated recurrence and pulmonary hypertension in patients with isolated SVT.
