Abstract:
Objective
To investigate the incidence and risk factors of postoperative deep vein thrombosis (DVT) in patients undergoing arthroscopic surgery, providing reliable clinical reference for the prevention and follow-up time of DVT after arthroscopy.
Methods
A prospective cohort study was conducted to compare the early and long-term occurrence of DVT in lower limbs of patients after arthroscopy in Jinjiang Hospital from January first to December 31, 2023, by analyzing their general data, relevant laboratory indicators,and postoperative DVT ultrasound follow-up results; The patients with DVT demonstrated by preoperative ultrasound were excluded. According to the time point of postoperative DVT, the patients were divided into early DVT group and forward DVT group. Independent sample t test was used for quantitative data, and chi square test was used for count data to identify statistically significant risk factors between the two groups and explore the risk factors that cause early and forward DVT in patients after arthroscopy surgery.
Results
A total of 171 patients were included in this study, including 13 cases (7.6%) with early DVT: 10 cases of calf intermuscular vein, one case of tibial vein combined with calf intermuscular vein, one case of fibular vein, and one case of great saphenous vein combined with calf intermuscular vein in the thigh segment. Among them, 14 cases (8.1%)experienced forward DVT: 10 cases of calf intermuscular vein, one case of fibular vein, two cases of fibular vein combined with calf intermuscular vein, and one case of posterior tibial vein combined with fibular vein and calf intermuscular vein. Compared with the early DVT group, the time difference of thrombus absorption was statistically significant (χ2=-2.816, P<0.01).
Conclusion
Late DVT after arthroscopy has a certain incidence rate with longer absorption time of the thrombus, and seriously consideration should be taken by clinical doctors.
