Q & A with Dr. Z – Lower Extremity AV Fistula Peripheral Segments

by David Zielske, MD, CIRCC, COC, CCVTC, CCC, CCS, RCC

Question: Lower Extremity AV Fistula Peripheral Segments
For lower extremity AV fistula peripheral segments – what is the adjacent segment of native artery, peri-anastomotic region/arterial anastomosis? Does this mean only the common femoral artery or also the iliac arteries? Please clarify.

The iliac veins are in the central segment of the dialysis circuit in the lower extremity, just like the subclavian and brachiocephalic veins in the upper extremity. Only the femoral veins are in the peripheral segment.
