Aberrant veno-lymphatic communication noted in a dog.

Summary Postmortem lymphangiography with hydrosoluble contrast medium was performed in the hind legs of dogs. On one occasion, the lymphangiogram demonstrated the free passage of contrast medium from the popliteal node into the femoral vein.

Prevention of induced atherosclerosis by diversion of bile or blockade of intestinal lymphatics in dogs.

The prevention of induced hypercholesterolemia and atherosclerosis was studied by means of intestinal lymphatic blockade and of bile diversion in the dog. Hypercholesterolemia and atherosclerosis were produced by high cholesterol feeding after induction of hypothyroidism with radio-iodine plus thiouracil. Complete diversion of bile, by shunting all bile into the urinary bladder, effectively prevented hypercholesterolemia and atherosclerosis; in contrast, blockade of the intestinal lymphatics failed to prevent the consequences of the atherogenic regimen, because of the development of collateral lymphatic channels
