Endovenous radiofrequency ablation in combination with TriVex for treatment of chronic venous insufficiency of the lower extremity

objective To evaluate the therapeutic efficacy of endovenous radiofrequency ablation in combination with TriVex for the treatment of chronic venous insufficiency (CVI)of the lower extremity.Methods One hundred and fifty CVI cases(150 limbs)were randomly assigned to Group A(75 limbs)and Group B(75 limbs).Patients in Group A were treated with greater saphenous vein radiofrequency ablation procedures in combination with TriVex.Patients in Grpup B were treated with greater saphenous vein traditional stripping operation in combination with TriVex.The short-term results in hospital and patient self-assessment for the operation at postoperative 4 week were compared with each other:The changes of CEAP classification and venous clinical severity score(VCSS)were compared. Results Operation time was(67±11)min in Group A versus(69-4-9)min in Group B(P＞0.05).Postoperative pain,average hospital stay in Group A were significantly less and shorter than in Group B(P ＜0.05).The scores of selfassessment for the operation were(11.21±2.00)in Group A versus(10.52±2.08)in Group B(P＜0.05).The change of CEAP classification and VCSS were statistically significant after operation in both groups(P＜0.01).The VCSS decreased 4.6 ±2.5 in Group A versus 4.3±2.7 in Grpup B(P＞0.05).Conclusions Endovenous radiofrequency ablation in combination with TriVex for treatment of CVI are effective,less traumatic,of fast recovery.CEAP classification and VCSS are useful tools for assessing outcomes after the operation.
