Local Cytokine Concentrations and Oxygen Pressure Are Related to Maturation of the Collateral Circulation in Humans

open access: yesJournal of the American College of Cardiology, 2009
ObjectivesOur aim was to determine cytokine and oxygen gradients over the collateral circulation in humans.BackgroundThe molecular background of the maturation of the collateral circulation in response to coronary narrowing is poorly understood in humans,

Development of Coronary Collateral Circulation

Annual Review of Medicine, 1977
Collateral coronary arteries provide alternate routes for delivery of blood to myocar­ dium distal to major coronary-artery obstructions. These channels may be extracar­ diac, endomural, or arterioluminal in origin (I). One additional source of collateral myocardial blood flow is from deliberate attempts to surgically augment blood flow to ischemic ...

Collateral Circulation in the Sigmoid Colon

Archives of Surgery, 1955
The blood supply to the sigmoid colon and upper rectum is traditionally related to a "critical point" beyond which ligation will cause necrosis. Most surgeons doubt this theory, but experimental proof is lacking. The arteries to the sigmoid colon and rectum have been reinvestigated with special reference to this question in fresh human autopsy material.

Pathways of Cerebral Collateral Circulation

Radiology, 1960
Despite Considerable anatomical proof to the contrary, the myth of “end-artery” circulation to the brain has been perpetuated in textbooks for years. This interpretation of Cohnheim's original theory concerning infarction and his concept of end-arteries, published in 1872, has led to the erroneous assumption that cerebral collateral circulation is ...
