CORONARY COLLATERAL CIRCULATION
American Journal of Roentgenology, 1973In the presence of obstructing coronary atherosclerosis, collateral circulation may develop through pre-existing anastomotic channels which are present, though nonfunctional, in normal hearts. These anastomoses connect various branches of the same coronary artery or different coronary arteries.

Coronary Collateral Circulation
Chest, 1974Collateral coronary channels represent obvious compensatory mechanisms for the delivery of nutrients to the myocardium. In spite of extensive basic research, we are still unaware of the factors determining adequate compensatory adjustments. Extensive human pathologic studies have presented a quantitative overall view, but have said little about the ...

The dynamics of the coronary collateral circulation
Nature Reviews Cardiology, 2014Coronary collaterals are present at birth, with wide interindividual variation in their functional capacity. These vessels protect jeopardized myocardium, and the number of collaterals and the extent of their coverage are associated with improved survival in patients with coronary heart disease.

Background and Purpose- The development of leptomeningeal collateral artery network might be adversely affected by small vessel wall alteration. We sought to determine whether small vessel disease (SVD) burden may impact collateral development in ...

Background Leukoaraiosis and collateral blood flow are processes that involve small vessels, the former related to flow within the deep perforating arterioles and the latter involving the small, cortical pial-pial connections, both of which are ...

Collateral Circulation in Health and Disease
Archives of Surgery, 1957The present studies were carried out because of a need for a better understanding of the functional capacity of the collateral circulation in health and in disease. Aortography has been an important method of obtaining anatomic evidence of the collateral circulation 1 ; however, little attention has been paid to its functional effects.
