Preserving dialysis access

In the case of insufficient dialysis power or a closed shunt, the cause is examined by imaging. Treatment and timing are agreed with nephrology and Vascular surgery.

Specific requirements

Care is guided by the specific anatomy of the dialysis access. Creating a new endovascular fistula requires anatomically suitable vessels.

Treatment is based on your findings and personal treatment goals. We discuss benefits, risks and alternatives with you during an individual informed consent consultation.

Consultation and preparation

Bring existing doctor’s letters, image data, and a current medication plan. Change medications please only after medical consultation. We discuss benefits, risks and alternatives with you.
