[Efficacy of treatments in patients with symptomatic venous thrombosis after knee arthroscopic surgery].

Objective: To confirm the incidence of the symptomatic venous thrombosis and evaluate the efficacy of early treatments in patients with symptomatic venous thrombosis after knee arthroscopic surgery. Methods: From June 2010 to December 2015, 19 patients with symptomatic venous thrombosis hospitalized after knee arthroscopy were retrospectively analyzed by visual analogue scale (VAS) in Department of Orthopaedics, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Results: The incidence of symptomatic venous thrombosis after knee arthroscopy in our hospital was about 1.27%.15 cases were completely followed up to the end point.The clinical symptoms of those patients were statistically relieved[(4.74±0.73)vs(1.89±0.66), (1.60±0.51), P <0.05)]; [(46.68±4.09) cm vs (45.00±4.07)cm, P >0.05; (46.68±4.09) cm, (43.73±4.04)cm, P <0.05)]; and in one month ultrasonic review, 5 cases were confirmed to get revascularization, while with 4 cases get partially response.No significance was found in symptomatic relief-revascularization correlation and background factors comparison.No pulmonary embolism were observed among those cases. Conclusion: Although the incidence of symptomatic venous thrombosis after knee arthroscopy is relatively low, caution should still be needed to get early detection, diagnosis and intervention.The conventional conservative treatments can usually get a relatively good and safe clinical outcome.
