End artery End artery An end artery (or terminal artery) is an artery that is the only supply of oxygenated blood to a portion of tissue. Arteries which do not anastomose with their neighbors are called end arteries. There is no collateral circulation present besides the end arteries. Examples of an end artery include the splenic artery that supplies the spleen and the renal artery that supplies the kidneys. End arteries are of particular interest to medicine where they supply the heart or brain because if the arteries are occluded, the tissue is completely cut off, leading to a myocardial infarction or
Anomalous left coronary artery from the pulmonary artery Anomalous left coronary artery from the pulmonary artery Anomalous left coronary artery from the pulmonary artery (ALCAPA or Bland-White-Garland syndrome or White-Garland syndrome) is a rare congenital anomaly in which the left coronary artery (LCA) branches off the pulmonary artery instead of the aortic sinus. After birth, the pressure in other coronary arteries (namely the RCA) will have a pressure that exceeds the LCA and collateral circulation will increase. This, ultimately, can lead to blood flowing from the RCA into the LCA (retrograde) and into the pulmonary artery, thus forming a left-to-right shunt. The syndrome is named for Edward Franklin
