Long-term viability and lower chance of complications in dialysis can be achieved by using a new approach, according to a new study. The strategy could help improve the safety and long-term performance of dialysis for patients with chronic kidney disease, a widespread and debilitating chronic condition.
‘RADAR procedure for dialysis results in long term viability and reduced risk of complications compared to conventional procedures.’

Chronic kidney disease affects approximately 30 million Americans and imposes a massive burden on the healthcare system, causing more than $84 billion in healthcare costs in 2017, according to the CDC.Read More..
Many patients with advanced disease suffer from kidney failure and rely on dialysis to replace the lost function of their kidneys.
Currently, clinicians perform dialysis by accessing the circulatory system through arteriovenous fistulae, or connections made between arteries and veins, during surgery. However, only half of arteriovenous fistulae remain wide enough after one year, necessitating further surgeries and predisposing some patients to complications like neointimal hyperplasia.
In a previous trial, several co-authors of the current study developed a new and safer procedure named RADAR to create arteriovenous fistulae.
Instead of using the conventional vein-to-artery approach, RADAR instead starts with the radial artery and attaches it to a vein in the forearm.

The authors discovered that fistulae created with RADAR matured more quickly, were more likely to remain accessible for dialysis, and were less likely to require reintervention after 36 months. Furthermore, RADAR decreased the likelihood of neointimal hyperplasia and improved blood flow dynamics in rat models.
