    Abstract:
    Segments of the small intestine and hind extremities of dogs were perfused under the condition of complete arterio-venous flow reversal (AVFR). In the intestinal segments, the peripheral resistance under AVFR conditions was 4.4 times higher than under orthograde perfusion. Petechiae and hemorhagic infarction were observed. The average flow resistance of the hind extremities was 2.4 times higher than the resistance in control extremities. The pO2 and the O2 saturation in the blood, outflowing from the AVFR extremity was lower than in the control extremity, however, the pO2 was higher. The oxygen consumption was somewhat lower than in the control extremity. It is concluded that by complete AVFR an extremity may be supplied sufficiently with oxygen at least temporarily.
