Lower extremity arteriovenous fistula with central venous stenosis iliocaval stenting to treat venous outflow obstruction.

Maintenance of hemodialysis access for end-stage renal disease continues to be a major challenge for vascular surgeons, nephrologists, and primary care physicians. This case report highlights the complication and treatment of lower extremity central venous stenosis, allowing continued dialysis access for a patient with limited remaining fistula options. This stenosis resulted from the prolonged use of a lower extremity central venous catheter. This case highlights the importance of imaging the central veins in obstruction of lower extremity fistulas. Once detected, as in the upper extremity, this can be effectively treated using balloon dilation and stenting.
