Patient anatomy plays a crucial role in the success of vascular access for dialysis. For hemodialysis, effective access to the bloodstream is essential, as this is how the blood is drawn for filtration and returned to the body. The vascular structures available for access, such as veins and arteries, vary significantly among individuals. Factors like the size, depth, and condition of the veins can influence whether a patient can successfully receive dialysis through methods like arteriovenous (AV) fistulas, grafts, or central venous catheters.

If a patient has poor vascular anatomy or access sites, it can lead to complications such as thrombosis or inadequate blood flow during treatment. Therefore, understanding a patient's anatomy is vital for healthcare providers in planning and establishing the most appropriate and effective vascular access route for dialysis, greatly impacting treatment outcomes. This knowledge can also guide decisions on whether to use temporary or permanent access options based on the patient's individual anatomical characteristics.
