Brief summary
This study is a prospective, multicenter, real world, observational study intended to understand tmechanical thrombectomy in the treatment of acute deep venous thrombosis of lower extremities, It is estimated that 600 patients with DVT were enrolled in the group at 24 centers nationwide from May 2022 to May2024. we can obtain data on the incidence of sequelae of deep venous thrombosis after PMT, and analyze the factors that may affect the efficacy of PMT.
Detailed description
Through inclusion and exclusion criteria, 600 patients were collected. This experiment was an observational study case series, and no control group was established. 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. The main endpoints were the patency rate of lower extremity deep veins at 6 months after operation and the incidence of PTS (Villalta score) at 2 years after operation.
