PTS findings of venous stasis dermatitis, venous stasis ulcers, chronic lower-extremity pain that limits aerobic activities, chronic lower-extremity pain that limits activities of daily living, and chronic lower-extremity pain at rest were all absent. Data for contralateral differences in circumference are given as median (range).
PTS indicates post-thrombotic syndrome.
