| arterial embolism | <cardiology, physiology> A sudden interruption in arterial blood flow to an organ or body part (extremity). The blockage is caused by a blot clot or atherosclerotic plaque that has moved through the arterial circulation from one position to another. The resulting mechanism is the same regardless of cause or location. Oxygen deprivation to the tissues distal to the occlusion become ischaemic and die (necrosis). Atrial fibrillation is a risk factor for arterial embolism due to the release of blood clots from the fibrillating heart. Blood vessel injury and increased levels of platelets can also be a risk for arterial embolism. Symptoms vary with location, but pain, coolness to an extremity and a absent or diminished pulse are common in the case of an extremity embolism. Treatment is often surgical or involves the use of blood clot dissolving medications (for example streptokinase) delivered selectively to the site of the blockage. (17 Oct 1997) |

| arterial flap | A flap that includes a direct specific artery within its longitudinal axis. Synonym: arterial flap. (05 Mar 2000) |
| arterial forceps | A locking forceps with sloping blades for grasping the end of a blood vessel until a ligature is applied. (05 Mar 2000) |
| arterial grooves | Branching grooves on the interior surface of the cranial vault in which the meningeal arteries course, the most prominent of which are related to branches of the middle meningeal artery. Synonym: sulci arteriosi. (05 Mar 2000) |
| arterial hyperaemia | active hyperaemia |
| arterial hypotension | See: hypotension. (05 Mar 2000) |
| arterial ligament | The remains of the ductus arteriosus. Synonym: arterial ligament, Botallo's ligament. (05 Mar 2000) |
| arterial line | An intra-arterial catheter. (05 Mar 2000) |
| arterial murmur | A murmur heard on auscultating an artery. (05 Mar 2000) |
| arterial nephrosclerosis | Patchy atrophic scarring of the kidney due to arteriosclerotic narrowing of the lumens of large branches of the renal artery, occurring in old or hypertensive persons and occasionally causing hypertension. Synonym: arterionephrosclerosis, senile nephrosclerosis. (05 Mar 2000) |
| arterial occlusive diseases | Diseases in which arterial vessels are partially or completely obstructed or in which the blood flow through the vessels is impeded. (12 Dec 1998) |
| arterial perfusion | <procedure> Treatment in which blood is drawn from a patient, pumped through a machine that adds anticancer drugs and returned to the major artery supplying the limb being treated. (16 Dec 1997) |
| arterial plethysmography | <investigation, procedure> A test which measures the systolic blood pressure of a normal extremity compared to an upper extremity. The test is usually used to detect arterial blockage in the lower extremities. There should be less than 20 mm of Hg difference in systolic blood pressure between the upper and lower extremities. More than this can indicate arterial occlusive disease or arterial blockage. (17 Oct 1997) |
| arterial sclerosis | <cardiology, disease> Imprecise term for various disorders of arteries, particularly hardening due to fibrosis or calcium deposition, often used as a synonym for atherosclerosis. (17 Oct 1997) |
| arterial segments of kidney | Regions of the kidney supplied by end arteries branching from the renal arteries; they are named anterior inferior segmentum, anterius superior segmentum, inferior segmentum, posterior segmentum, and superior segmentum. Synonym: segmenta renalia, arterial segments of kidney. (05 Mar 2000) |
| infusions, intra-arterial | Regional infusion of drugs via an arterial catheter. Often a pump is used to impel the drug through the catheter. Used in therapy of cancer, upper gastrointestinal haemorrhage, infection, and peripheral vascular disease. (12 Dec 1998) |

| intermesenteric arterial anastomosis | The series of arterial arches formed in the mesentery by anastomoses between adjacent jejunal and ileal arteries and from which vasa recta arise. The arterial arcades of the ileum are shorter and more complex than those of the jejunum. See: arterial arches of ileum, arterial arches of jejunum. Synonym: intermesenteric arterial anastomosis, Riolan's arc, Riolan's arcades. (05 Mar 2000) |

| intra-arterial | Into an artery. (16 Dec 1997) |
| intra-arterial pressure | The pressure of the blood within an artery, the arterial pressure. Also called the arterial tension. (12 Dec 1998) |
| tension, arterial | The pressure of the blood within an artery, the arterial pressure. Also called the intra-arterial pressure. (12 Dec 1998) |
| 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) |
| lesser arterial circle of iris | An arterial circle near the pupillary margin of the iris. Synonym: circulus arteriosus iridis minor. (05 Mar 2000) |
| arterial capillary |
a type of minute vessel lacking a continuous muscular coat, intermediate in structure and location between an arteriole and a capillary; called also precapillary, precapillary arteriole, and metarteriole.
