A Brief Etymology of the Collateral Circulation

A brief etymology of the collateral circulation.

It is well known that the protective capacity of the collateral circulation falls short in many individuals with ischemic disease of the heart, brain, and lower extremities. In the past 15 years, opportunities created by molecular and genetic tools, together with disappointing outcomes in many angiogenic trials, have led to a significant increase in the number of studies that focus on: understa...

The myocardial collateral circulation.

Collateral circulation.

BACKGROUND The collateral circulation plays a pivotal role in the pathophysiology of cerebral ischemia. Current knowledge of the collateral circulation remains sparse, largely because of prior limitations in methods for evaluation of these diminutive routes of cerebral blood flow. SUMMARY OF REVIEW Anatomic descriptions of the collateral circulation often focus on more proximal anastomoses at...

Dynamics of the Collateral Circulation

W HEN the proximal portion of the subclavian artery is occluded, numerous anastomotic vessels in the neck and chest wall are available to maintain the circulation to the arm." 2 Another collateral pathway, consisting of both vertebral arteries,3 has recently created much interest. Contorni4 showed, by the use of selective arteriography, that dye passed up the right vertebral artery to its junct...

The human coronary collateral circulation.

BACKGROUND Coronary collaterals are an alternative source of blood supply to myocardium jeopardized by ischaemia. Well-developed coronary collateral arteries in patients with coronary artery disease (CAD) mitigate myocardial infarcts and improve survival. METHODS AND RESULTS Collateral arteries preventing myocardial ischaemia during brief vascular occlusion are present in 1/3 of patients with...
