Clinical Study On The Effect Of Non-valvular Function Reconstruction On Deep Venous Valve Function Of Lower Extremity

Objective To investigate the effect of non-valvular function reconstruction on deep venous valve function in patients with chronic venous insufficiency of lower extremity.Methods Retrospective analysis of Patients with deep venous insufficiency of lower extremity who had no history of venous thrombosis admitted to our hospital from April 2015 to April 2018.All patients were hospitalized with varicose veins of lower extremities and some ulcers.The CEAP grade was C2-C6.All patients underwent color Doppler ultrasound and lower extremity venography before operation.According to different surgical methods,they were divided into iliac vein stenting group(iliac vein group)and saphenous vein high ligation plus stripping group(superficial vein group).And Subfascial endoscopic perforators surgery(SEPS)combined with high saphenous vein ligation and stripping group(traffic vein group).The paired t-test was used to compare the preoperative and postoperative valve closure time(VCT),maximum velocity(Vmax),and venous clinical severity score(VCSS)in the three groups.Results A total of 110 patients,a total of 123 limbs,aged 28-74 years,mean age 52.43 ± 9.88 years,63 female patients,47 male patients.The mean values of the three months before and after VCT in the iliac vein group were 2.46±1.36 s and 1.68±1.67 s,respectively;the mean values of Vmax were 33.66±8.26cm/s and 26.80±9.73cm/s,respectively;VCSS The mean values were 5.59±2.13 and 5.00±1.54,respectively.The difference of VCT,VCSS and Vmax in the sacral vein group was statistically significant(P<0.05).The average values of preoperative and postoperative three months of VCT in the superficial vein group were 2.23±0.84 s and 1.60±0.75 s,respectively;the mean values of Vmax were 19.92±4.91cm/s and 21.87±5.61cm/s,respectively;VCSS The mean values were 5.16±1.64 and 1.22±1.17,respectively.The mean values of the three months before and after the VCT of the limbs of the traffic vein group were 3.17±1.41 s and 2.39±1.56 s,respectively.The mean values of Vmax were 27.25±6.09.The mean values of VCSS were 8.02±2.28 and 3.33±1.76,respectively.There were significant differences between the superficial vein group and the traffic vein group before and after VCT and VCSS(P<0.05).There was no significant difference in the change of Vmax(P>0.05).Conclusions 1.For patients with primary deep venous valvular insufficiency of lower extremity,high ligation and stripping of great saphenous vein and SEPS combined with high ligation and stripping of great saphenous vein can improve deep venous valvular function of lower extremity and have good clinical effect.2.Iliac vein stenting can improve the function of deep vein valves of lower extremities and improve the clinical symptoms in patients with deep vein valvular insufficiency of lower extremities secondary to non-thrombotic iliac vein stenosis.For patients with severe valvular insufficiency,secondary surgery is recommended.
