TESTS FOR COLLATERAL CIRCULATION IN THE EXTREMITIES

Archives of Surgery, 1946
PRIOR to the introduction of the reactive hyperemia test by Matas,1there was no method of assaying before operation whether surgical occlusion of the great arteries would be followed by relatively adequate circulation in the extremity or whether some ischemic disaster would result. Indeed such precautions are still sometimes omitted, if one is to judge

Biology of the Collateral Circulation

1980
Collateral vascular channels are those arteries and veins which are interposed as connecting links capable of bypassing areas of vascular occlusion. Their basic function is to carry blood in sufficient quantities to maintain the circulatory equilibrium of the part they serve.

Effects of the collateral circulation of the heart

The Bulletin of Mathematical Biophysics, 1965
Collateral circulation minimizes the myocardial injury which results from narrowing of a coronary artery. A large collateral circulation has disadvantages, however. It may divert so much of the limited blood flow through the adjacent nonarteriosclerotic coronary artery that the blood supply of the normal muscle supplied by that artery may be inadequate

Collateral Circulation of the Brain

1992
The brain is an electrical organ with a high energy utilization rate. In the awake state energy consumption of cerebral cortex amounts to approximately 15 mmol~P/g/min, i.e. as much or more than that of liver or heart muscle. The energy demands of the brain are almost exclusively covered by oxidative metabolism of glucose which yields 38 mol~P per mol ...
