Collateral circulation

Circulation bypassing the main (occluded) vessels. Such circulation develops when an occlusion of a main vessel exists.

It is part of the correction and compensation mechanism, by which the growth of natural vessels bypassing the occlusion is promoted.

Such natural bypasses are only partially efficient and seldom constitute an adequate solution of a significant atherosclerotic problem.

Regular aerobic sport activity helps in the development of such natural bypasses.
