Abstract:
Hemodialysis access is a lifeline for patients with terminal stage renal disease.Many patients with terminal stage renal disease rely on this access for receiving regular hemodialysis to stay alive.Therefore,it is essential to ensure long-term patency of the access.However,the patency of access can be affected by a lot of factors,such as stent implantation,prolonged irritation from electronic devices,and venous hypertension,all of which can cause reactive endothelial hyperplasia with consequent stenosis or occlusion of the access.Nowadays,the conventional methods to maintain the patency of hemodialysis access include percutaneous transluminal angioplasty(PTA)and percutaneous transluminal stenting(PTS).However,in some patients the tissue of the obstructed site has already been completely organized or has become calcified and hardened.In this case,the recanalization of the obstructed site is difficult to be accomplished by the conventional method,and sharp puncturing is required to achieve effective recanalization of the obstructed site.This paper aims make a comprehensive review concerning the surgical recanalization methods used for central venous occlusive diseases in hemodialysis patients so as to provide useful reference for clinical practice.
