| balloon dilatation | Nonoperative repair of occluded vessels, ducts, or valves by insertion of a balloon catheter. It is used to treat varices, torn retinas, renal and biliary calculi, gastric, bronchial and rectal stenoses, and heart valves, and includes catheterization with fogarty and foley catheters. (12 Dec 1998) |

| small bowel dilatation | <radiology> Mnemonic: SOS, sprue, obstruction / ileus, scleroderma (collagen-vascular disease) normal width: less than 3 cm (12 Dec 1998) |
| stage of dilatation | The part of labour when the cervix dilates fully (to 10 centimeters). Also called the first stage of labour. (12 Dec 1998) |
| stomach dilatation | Distention of the stomach with retained secretions, food, and/or gas due to obstruction, ileus, or denervation. (12 Dec 1998) |
| digital dilatation | Use of the finger or finger-tip to enlarge an orifice or opening, such as enlarging the orifice of a sclerosed mitral valve surgically. (05 Mar 2000) |
| dilatation | The condition, as of an orifice or tubular structure, of being dilated or stretched beyond the normal dimensions. (18 Nov 1997) |
| dilatation and curettage | This gynaecological procedure involves dilating the cervix (opening to the uterus) such that a surgical curette may be passed into the uterus. The surgeon uses the curette to remove the inner lining of the uterus (endometrium). This procedure is often performed to correct dysfunctional uterine bleeding. (27 Sep 1997) |
| dilatation, pathologic | The condition of an anatomical structure's being dilated beyond normal dimensions. (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) |
