The patency of the lower extremity veins was assessed by lower extremity venous ultrasound or lower extremity venography. According to the postoperative symptoms and signs of the patients, the Villata score, (VEINS QoL)/Sym questionnaire and VCSS score were used to understand the PTS situation.Postoperative clinical follow-up was performed at 6 months, 12 months, 18 months, and 24 months.
