Abstract:
Objective To explore the risk factors of supplementary injection after foam sclerotherapy for varicose veins of lower extremities and its impact on blood coagulation function.Methods A total of 185 patients with varicose veins of lower limbs diagnosed in the First People's Hospital of Zunyi from January 2018 to December 2021 were selected.The corresponding pathological data were collected,and the D-dimer,thrombin time,and fibrinogen level of patients were detected 1 d before and 1 d after the surgery.The postoperative video phone follow-up lasted until 6 months after the surgery.The patients were divided into single treatment group and supple-mentary treatment group according to whether supplementary injection of foam sclerosing agent was needed during the follow-up.Propensity matching on the data between the two groups was conducted,and the correlation between disease course data,coagulation factors,and the occurrence of supplementary injection was analyzed.A time series model for the incidence of supplementary injection was established,and the therapeutic effect and complica-tions were observed.Results After propensity matching,there was still significant difference in the degree of lesion between the two groups(P<0.05).On the first day after surgery,there was significant difference in the D-dimer and fibrinogen groups between the two groups(P<0.05),and but no significant difference in thrombin time(P>0.05).The occurrence of supplementary injection was significantly correlated with D-dimer,fibrinogen,thrombin time,and first-time injection dose(P<0.05),and the incidence of supplementary injection was higher in patients who received first-time injection in January,August,September,and December.Both groups achieved successful treatment 6 months after surgery,and there was no significant difference in the incidence of compli-cations.Conclusion Patients with lower limb varicose veins of C3/C4 are more likely to require supplementary injection compared to patients with other levels.The level of D-dimer and fibrinogen at 1 d after surgery is positively correlated with the occurrence of supplementary injection,while the dose of the first injection is negatively corre-lated with the occurrence of supplementary injection.
