| transposition of arterial stems | Congenital malformation in which the aorta arises from the morphologic right ventricle and the pulmonary artery from the morphologic left ventricle resulting in two separate and parallel circulations. The condition is lethal unless some communication exists between the systemic and pulmonic circulation after birth; otherwise, unoxygenated venous blood inappropriately enters the systemic circulation, and oxygenated pulmonary venous blood is inappropriately directed to the pulmonary circulation. The life sustaining communication may be an intra-atrial passage or a patent ductus arteriosus. Synonym: transposition of arterial stems. (05 Mar 2000) |

| plant stems | Parts of plants that usually grow vertically upwards towards the light and support the leaves, buds, and reproductive structures. (12 Dec 1998) |

| bacterial transposition | <molecular biology> A short sequence of DNA (known as a transposon) which can change location on the bacterial genome (the sum total of all of the bacterium's DNA) and contains genes which code for proteins that enable it to change location. They are useful because they can also contain genes for other things, like antibiotic resistance, and because they can be introduced into a bacterial genome by a researcher. (09 Oct 1997) |
| penoscrotal transposition | Deficient ventral penile shaft skin which is buried in scrotum or tethered to scrotal midline by a fold or web of skin. The urethra and erectile bodies are usually normal. Synonym: penis palmatus, penoscrotal transposition. (05 Mar 2000) |
| corrected transposition of the great vessels | Anatomically or physiologically corrected malposition of the great arteries. In anatomically corrected transposition, they arise from the correct ventricles but have an abnormal relation to each other (actually a malposition rather than a transposition.) In physiologically or functionally corrected transposition, the aorta arises from a systemic ventricle that has the morphologic characteristics of a right ventricle, and the pulmonary artery arises from a "venous" ventricle that has the morphologic characteristics of a left ventricle. (05 Mar 2000) |
| transposition | <molecular biology> The movement of a piece of DNA around the chromosome (from one gene to another part of the genome), usually through the function of a transposable element. (09 Oct 1997) |
| transposition of great vessels | <embryology> A congenital cardiovascular malformation in which the aorta arises entirely from the right ventricle and the pulmonary artery from the left ventricle, so that the venous return from the peripheral circulation is recirculated by the right ventricle via the aorta to the systemic circulation without being oxygenated in the lungs. There is an intracardiac shunt, increased pulmonary vascularity, cyanosis. The chest X-ray shows that the heart size may be normal at birth, but it gradually enlarges with a globular or egg-on-its-side appearance. (27 Jun 1999) |
| transposition of the great vessels | Congenital malformation in which the aorta arises from the morphologic right ventricle and the pulmonary artery from the morphologic left ventricle resulting in two separate and parallel circulations. The condition is lethal unless some communication exists between the systemic and pulmonic circulation after birth; otherwise, unoxygenated venous blood inappropriately enters the systemic circulation, and oxygenated pulmonary venous blood is inappropriately directed to the pulmonary circulation. The life sustaining communication may be an intra-atrial passage or a patent ductus arteriosus. Synonym: transposition of arterial stems. (05 Mar 2000) |
| truncus vs. Transposition | <radiology> May look very similar, increased PBF and cyanosis (admixture), distinguishing feature: aortic arch, right aortic arch in 30% of TA vs. Only 5% of TGV (12 Dec 1998) |
| acromial arterial network | A vascular network between the acromion and the skin of the shoulder, formed by anastomoses of the acromial branch of the suprascapular artery with the acromial branch of the thoracoacromial artery. Synonym: rete acromiale, acromial plexus. (05 Mar 2000) |
| alveolar-arterial oxygen difference | The difference or gradient between the partial pressure of oxygen in the alveolar spaces and the arterial blood: P(A-a)02. Normally in young adults this value is less than 20 mm Hg. See: alveolar gas equation. (05 Mar 2000) |
| arterial | <anatomy> Pertaining to an artery or to the arteries. (18 Nov 1997) |
| arterial arcades | A series of anastomosing arterial arches, as the intestinal arterial arcades between the branches of the jejunal and ileal arteries in the mesentery and the pancreaticoduodenal arteries on the head of the pancreas. (05 Mar 2000) |
| arterial arches of colon | Anastomosing branches of the colic arteries that form arch's in the mesocolon from which the walls of the colon are supplied. See: marginal artery of colon. (05 Mar 2000) |
| arterial arches of ileum | Arches formed in the mesentery by branches of the superior mesenteric artery from which vessels (vasa recta) arise to supply the wall of the ileum. See: intestinal arterial arcades. (05 Mar 2000) |
| arterial arches of jejunum | Arch's formed in the mesentery by branches of the superior mesenteric artery from which vessels (vasa recta) arise to supply the walls of the jejunum. See: intestinal arterial arcades. (05 Mar 2000) |
