Abstract:
Objective To observe the efficacy of Venovo venous stent for treating post-thrombotic syndrome(PTS)after lower extremity deep venous thrombosis(DVT).Methods A total of 61 patients with PTS after lower extremioty DVT who underwent iliac vein stent implantation were retrospectively enrolled,including 33 cases underwent Venovo stent(Venovo stent group)and 28 cases underwent conventional stent implantation(conventional stent group).The technical success rates and perioperative complications,Villalta score and venous clinical severity score(VCSS)before and 6 and 12 months after treatment,as well as the primary stent patency were compared within and between groups.Results The technical success rate was 100%in both groups,and no significant difference of the incidence of perioperative complications was found between groups(P=0.187).There was no significant difference of Villalta score nor VCSS between groups before treatment(both P＞0.05),while significant decrease of Villalta score was noticed before and 6 or 12 months after treatment within both groups(all P＜0.05).No significant difference of Villalta score nor VCSS was found 6 months after treatment between groups(both P＞0.05),while significant difference of Villalta score and VCSS were observed in Venovo stent group compared with those in conventional stent group 12 months after treatment(both P＜0.05).No significant difference of primary stent patency rate was found between groups 6 and 12 months after treatment(both P＞0.05).Conclusion Venovo venous stent could be used to effectively treat PTS after lower extremity DVT.
