In severe kidney failure, the harmful substances and excess water that is formed during the breakdown of the food in our body and which are normally excreted in urine cannot be eliminated and accumulate in our body. Hemodialysis is a form of treatment that allows these substances to be eliminated from our body. The patient’s blood is passed through the tubes made of a thin membrane (dialyzer) and removed from the body as the membrane is mixed with a fluid passing through it (dialysis solution-dialysate). For this, some of your blood is taken from a vein or catheter in your arm through a needle or a tube (catheter). The filtered and cleaned blood is returned to your vein/catheter with the help of a second needle/catheter. This form of treatment is carried out continuously, at least 4 hours or more in each session. This process is carried out in our dialysis center by the nurses and physicians specializing in this field. Thetreatment is usually applied 3 times a week depending on your health. How many times a week and how many hours will be decided each month, based on your blood tests, physical examination and general condition.

In order to perform hemodialysis treatment, it is necessary to establish a suitable vascular access specific to this procedure. Vascular access is one of the most important elements of hemodialysis treatment.
