Buttonhole Technique in Hemodialysis / 대한내과학회지

ABSTRACT

Recently, dialysis population with arteriovenous fistula may have some problems about the cannulation due to aged, incompetent vessels. Thus alternative needling method, buttonhole technique has been suggested for the complicated cannulation route. In spite of various benefits, this technique is difficult to apply in Korean hemodialysis unit because it requires much time to form the buttonhole track or tunnel. Meanwhile, Choi et al. reported the superiority of buttonhole technique using the polycarbonate peg, Biohole(TM). Here, we review the buttonhole technique in hemodialysis including new buttonhole technique using the Biohole(TM).
