The leptomeningeal collateral circulation allows a very limited degree of compensation for this.

It provides collateral circulation to the upper limb.

In these cases, the supply may be divided, some vessels sacrificed with expectation of adequate collateral circulation.

This collateral circulation allows for blood to continue circulating if the subclavian is obstructed.

So, an important goal is to stimulate vascular growth for the collateral circulation to prevent the exacerbation of these diseases.

An example of the usefulness of collateral circulation is a systemic thrombo-embolism in cats.

Collateral circulation gives "tree root" or "spider leg" appearance.

This promotes a greater blood supply to areas of the heart that need it, and it also improves collateral circulation."

This selective sparing is due to the collateral circulation offered to macular tracts by the middle cerebral artery.

The body grows new blood vessels in wound healing, and as collateral circulation around blocked or atherosclerotic blood vessels.

Individuals with arterial thrombosis or embolism often develop collateral circulation to compensate for the loss of arterial flow.

The anastomosis between these vessels assists in establishing the collateral circulation after ligature of the common carotid or subclavian artery.

Patients often survive on the collateral circulation from the back (posterior) of the Circle of Willis, from the basilar artery.

All these vessels anastamose or join to connect the first part of the subclavian with the third part of the axillary, providing a collateral circulation.
