Kidney Disease
The ideal hemodialysis vascular access is one that provides reliable, complication-free access to deliver prescribed dialysis
Hemodialysis/dialysis is done when kidneys fail to function properly. A dialysis machine is an artificial/mechanical kidney that is used to filter out blood.
In this, blood of the patient is made to pass through that dialysis machine, circulated in it and then returned back to the patient. Two needles are inserted into the patient’s bloodstream to carry out the procedure.
It is required to be done at least three times per week. The aim of vascular access is to provide proper sites in order to draw out the blood. Arteriovenous fistula, arteriovenous graft, and venous catheter are three types of vascular accesses.
The vascular accesses are usually created in the arm and sometimes in legs.
A surgeon creates a connection between an artery and a vein that is called an Arteriovenous Fistula . The vein then undergoes enlargement and…

In preparation for vascular access, the patient should keep one arm reserved from where there should be no blood draws, intravenous lines (IVs) or taking of blood pressure. The vascular surgeon can prescribe a non-invasive duplex ultrasound, or a venogram. A venogram, special x-ray procedure. In this a contrast dye is injected into the veins, therefore, the detailed picture of the veins is taken. It is only required in patients having a lot of previous dialysis access procedures or venous anatomy is unclear. The vascular surgeon with his staff will advise the patient procedure prerequisites and medications.
