To the Editor: Permanent vascular access is a lifethan one hemodialysis access dysfunction (including AVF, sustaining measure for hemodialysis-dependent patients. Generally, tunneled cuffed catheters (TCCs) are regarded as a bridge access to arteriovenous fistula (AVF) or arteriovenous graft (AVG), and the guidelines discourage TCCs from being the first choice of permanent vascular access because of the higher risk of complications and shorter expected service life. However, notably, a subset (<10%) of hemodialysis patients require permanent access through a TCC because they have exhausted other arteriovenous access options.
