Objective To explore the effects of intracavitary radiofrequency ablation combined with sclerotherapy injection on symptom improvement and lower limb hemodynamics in patients with lower limb varicose veins.Methods Clinical data of 100 patients with lower extremity varicose veins treated in our hospital from January 2022 to January 2023 were retrospectively selected.According to the surgical method,the patients were divided into R group and S group,50 cases in each group.Traditional high ligation of great saphenous vein+exfoliation was performed in group S,intracavity radiofrequency ablation closure+ultrasound guided injection of foam sclerosing agent+spot exfoliation was performed in group R.The clinical status,lower extremity hemodynamic indexes before and after surgery,therapeutic effect 3 months after surgery,venous clinical severity score(VCSS),venous classification system(CEAP)grading before,3 months after and 6 months after surgery,and the occurrence of complications 6 months after surgery were compared between the two groups.Results Three months after surgery,the total effective rate in group R(90.00％)was obviously higher than that in group S(74.00％)(P＜0.05).The hospital stay,bedtime,and intraoperative bleeding in group R were obviously lower than those in group S,and the VAS score within 72 hours after surgery was obviously higher than that in group S(P＜0.05).Compared with preoperative,postoperative blood flow velocity of femoral deep vein,popliteal vein and external iliac vein in 2 groups was significantly increased(P＜0.05).The R group was higher(P＜0.05).The difference of VCSS score and CEAP score 3 months and 6 months after surgery between the two groups was statistically significant(P＜0.05).There was no statistically obvious difference in the incidence of adverse reactions between group R and group S at 6 months after surgery(P＞0.05).Conclusion Intraluminal radiofrequency ablation combined with hardener injection has a good therapeutic effect on patients with lower limb varicose veins,which can effectively improve the patient's condition,reduce hemodynamic effects,maintain hemodynamic stability,and have high safety.
