Abstract

Haemodialysis is required by the patients with end stage renal failure (ESRD). In recent years increase in number of patients with end stage renal failure resulted in shortage in availability of transportable organ which makes more number of people to relay on maintenance haemodialysis (MHD). Arteriovenousfistula(AVF), centralveincatheter (CVC), arteriovenousgrafts (AVG), peritoneal dialysis catheter(PDC) are generally used as access points for hemodialysis. The development of new technologies to provide wide range of access points for hemodialysis have been taken place in the past few years. These technologies overthrow the barriers like stenosis and infection involved in AVF, CVC, AVG, PDC. Endo arteriovenous fistula(EndoAVF), bioengineered grafts, early cannulation grafts provide long term access for hemodialysis. Furthermore drug coated balloons, covered stents enhance the techniques of accomplishing arteriovenous access. Innovations in pipeline technologies are considered to promote AVF maturation process and reduce primary failure rate. These novel innovations mainly focus on preventing the stenosis that occur after AVF creation which leads to nonmaturation of the AVF and stenosis that occur after maturation which leads to dysfunction, inadequate dialysis and reduced lifespan. These new technologies provide feasible access point making the patient comfortable and ease the process of dialysis and plays a pivotal role in improving the quality of life of patients on maintenance hemodialysis (MHD).
