[Effect of induced hypothermia on the capillary circulation of the liver]

Micro-angiographic studies of the liver, in dogs under established hypothermy, showed that the contrast injected in the portal vein does not perfuse the sinusoidal structures. This fact is, probably, due to the contraction of pre- and post-capillaries sphincters. On the contrary, in dogs under normal temperature the injected contrast largely perfused the capillaries and all supra-heptic vascular system.
