[New experimental documents on circulatory reversal by arteriovenous fistula in ischemia of the extremities].
The beneficial effects of circulatory reversal by lateral a.-v. fistula was confirmed in 20 hind limbs of dogs made ischaemic by Collagen embolisation. Although not done in the experiments presented here, rupture of the distal venous valves is advisable. The peripheral circulation was studied by measurement of venous pressures and by angiography. Retrograde infusions, with proximal tourniquet, confirmed reversal of flow veins to arteries. Return routes to the heart remain unknown.
