摘要Background Conventional high ligation and stripping of the great saphenous vein (GSV) has a good curative effect but is highly traumatic with a considerable relapse rate.Subfascial endoscopic perforator surgery (SEPS) plus endovenous laser treatment (EVLT) could be applied as individual therapy.This study aimed to evaluate the feasibility of performing combined SEPS and EVLT without impacting GSV in the management of valvular insufficiency of the lower-limb venous perforators.Methods Placement of lower-limb venous perforator insufficiency was marked by ascending phlebography in 83 affected limbs from September 2010 to June 2011.After randomization,SEPS was performed on 41 limbs to address the insufficiency of the venous perforators under the deep fascia,in combination with EVLT to close the superficial varicose veins without impacting the GSV.The remaining 42 limbs were treated using traditional GSV phlebectomy as controls.Results Postoperatively,all varicose veins were resolved,with lightening of the pigmentation and healing of the ulcer.Within a follow-up period of 5-11 months,no symptoms had recurred.Compared with the control group,the operation time,the number of incisions sutured,and the in-hospital time decreased on average by 1.5 hours,4.7,and 6.8 days,respectively (P ＜0.01 in all cases).Conclusion Combined SEPS and EVLT for treatment of valvular insufficiency of the lower-limb venous perforators offer the advantages of microtrauma and rapid cure.
