Background. The VNUS Closure is an endo­lu­mi­nal, per­cut­ane­ous cath­e­ter-based ­device using a radio­fre­quen­cy cur­rent to cause per­ma­nent clo­sure of the long saph­e­nous vein (LSV) as an alter­na­tive to high tie and strip­ping. This study ­describes our post­op­er­a­tive ultra­sound scan sur­veil­lance ­results of VNUS Closure cases over a one year peri­od.
Methods. Between March and August 2000, 79 ­patients had 127 legs treat­ed. Postoperative ultra­sound scans were per­formed in order to eval­u­ate per­sis­tence of a pat­ent super­fi­cial infe­ri­or epi­gas­tric vein at the saph­e­nof­e­mo­ral junc­tion (SFJ), stump ­length of the remain­ing SFJ and chang­es in mor­phol­o­gy and diam­e­ter of the ablat­ed LSV. Ten legs were cho­sen ran­dom­ly for this eval­u­a­tion at each fol­low-up appoint­ment.
Results. Fifty-seven per cent of the ­patients’ legs had a pat­ent SFJ-stump with a remain­ing pat­ent super­fi­cial epi­gas­tric vein but none of the ­patients ­showed neo­vas­cu­lar­i­sa­tion at the SFJ or rec­a­nal­isa­tion of the LSV. The stump ­length at the SFJ ­appeared to be get­ting small­er as our expe­ri­ence grew great­er.
Conclusions. This new tech­nique of radio­fre­quen­cy abla­tion pro­vides a min­i­mal ­access alter­na­tive to the clas­si­cal high tie and strip­ping. Our ­results to date show that this pro­ce­dure ­leaves a small pat­ent stump at the SFJ with no evi­dence of neo­vas­cu­lar­isa­tion and a com­plete­ly atro­phied ­closed LSV.
