collateral circulation

“Your heart can actually form its own bypass from exercising, so you can develop that collateral circulation,” she said.

“If you have coronary heart disease, even a little bit, which we all get as part of the aging process, if you are regularly exercising, your body will develop all of these blood vessels - that’s collateral circulation. That can actually help sustain life and prevent you from having a heart attack.”

They all had a proximal vessel occlusion, a small infarct core, and moderate-to-good collateral circulation.

When an artery becomes obliterated, whether from embolism or thrombosis, the part which it supplies should be surrounded with cotton wool and every effort made to favor the establishment of the collateral circulation.

When the collateral circulation is insufficient to remove the blood from a region whose efferent venous trunk is completely filled with a thrombus, the phenomena of stagnation are produced.
