Clinical contribution of the collateral circulation
to myocardial protection.
6 mm were not able to establish a collateral circulation
and thus fed with blood ischemic area, which places an emphasis on studies in which it was stated that a much greater importance in the collateral circulation
has completeness of the Willis circle because in this case, it has a protective role in the prevention of stroke in patients with occlusion of the internal carotid artery.
In these patients, demonstration of multiple flows related to collateral circulation
between the left and right coronary arteries on the interventricular septum by colored Doppler and presence of reverse flow from the coronary artery into the pulmonary artery on colored Doppler echocardiogram suggest this anomaly.
Later studies [6,7,8,9,10] have demonstrated that the possible mechanism of action of omental transfer is an increase in local collateral circulation
rather than any significant increase in blood flow.
But although all people have collateral blood vessels in their brains, collateral circulation
does not always occur.
Skinner and Strandness (3) claimed that exercise training increased collateral circulation
to the ischaemic muscle.
The patient experienced no postoperative neurologic deficit, and postoperative CTA of the brain revealed adequate collateral circulation
There is an extensive collateral circulation
associated with the subclavian and axillary arteries, particularly around the scapula.
With sustained treatment this increases collateral circulation
to the coronary arteries as well as to the body as a whole.
Contemporary evidence-based treatment is risk factor management, to stow the progression of atherosclerosis, and walking exercise programmes to assist the development of collateral circulation
However, it would be unusual for a patient to have any symptoms from such a procedure because adequate collateral circulation
(other arteries) takes over the region previously supplied by the LIMA.
They used a combination of occluding clips on the uterine arteries and the utero-ovarial ligaments were coagulated with bipolar forceps, thus reducing uterine perfusion to the collateral circulation
