Anterior chest wall axillary artery to contralateral axillary vein graft for vascular access in hemodialysis.

abstract：:Small blood vessels may play a more important role in artificial heart (AH) recipients than ever suspected before. Observations of elevated total peripheral resistance, low hematocrit, reduced oncotic pressure, high circulating blood volume, and arterial pulsations with nonpulsatile devices require consideration of pe...
