Study On The Change Of Venous Pressure And The Postoperative Effect Of Primary Deep Venous Insufficiency Of Lower Extremities

Objective:To explore the changes of lower limb venous pressure,lower limb venous reflux time and VCSS score in patients with primary lower extremity deep vein valve insufficiency(PDVI)before and after surgery,so as to analyze the effect of surgery.Methods :We prospectively collected and studied 58 patients who were admitted to the vascular surgery in our hospital from October 2021 to December2022,and who were confirmed as PDVI by B-ultrasound examination of lower limb veins and lower limb phlebography.According to the classification of Kistner,these patients with venous blood reflux of III and above or CEAP grading of 4and above were treated with superficial femoral vein ring and high ligation and stripping of great saphenous vein..The patients measured the static venous pressure(P0),dynamic venous pressure(Pmin)and the time taken when the pressure rose to P090% before operation,10 days after operation and 3 months after operation respectively;The time of ultrasonic reflux of lower limb veins before and after operation and the change of VCSS score of patients 3 months before and after operation can be used to judge the surgical effect and clinical cure.Fifty eight patients were compared with the mean values of P0,Pmin and RT90 of the affected limb,preoperative and postoperative 10 days,and postoperative 3 months,the mean values of the ultrasonic reflux time of the lower limb before and after surgery,and the VCSS scores before and after surgery.The statistical software SPSS24.0 was used for corresponding data processing.When P<0.05,it was considered that there was a statistical difference.Results:There was no significant difference in the mean value of P0 in 58 patients before and 10 days after operation(t=1.86,P>0.05);The mean value of Pmin and RT90 were compared with t=28.63 and t=29.82 respectively,P=0.000,with significant statistical difference;The pressure reduction ratio comparison t=29.55,P=000,with statistical difference.P0,Pmin and RT90 before and 3 months after operation were significantly different(t=11.26,t=35.31,t=29.01,P<0.05).The mean value of venous reflux time of lower limbs before and after operation was t=8.66,P<0.05,with significant statistical difference;Compared with the average value of VCSS score before and 3 months after operation,t=29.90,P<0.05,with significant statistical difference.Conclusion:1.Superficial femoral vein ring combined with high ligation and stripping of the great saphenous vein has a good postoperative effect on PDVI treatment.Significant improvement in lower limb venous hypertension and congestion after surgery.2.The quality of life of patients has been significantly improved after surgery.
