| arterial tension | The pressure of the blood within an artery, the arterial pressure. Also called the intra-arterial pressure. (12 Dec 1998) |
| arterial thoracic outlet syndrome | <syndrome> A rare disorder due to compression of the subclavian artery (with resultant poststenotic dilation) by a fully formed cervical rib; thrombi form in the dilated distal arterial segment, and distal limb ischemia may occur due to thromboembolic events. (05 Mar 2000) |
| arterial transfusion | Direct transfusion from an artery of the donor into an artery of the receptor. (05 Mar 2000) |
| arterial vein | <anatomy, vein> So called because it ramifies like an artery (portal vein) or because, while proceeding from the heart like an artery, it contains unoxygenated blood, like a vein (pulmonary artery). Synonym: vena arteriosa. (05 Mar 2000) |
| arterial wave | A wave in the jugular phlebogram due to transmission of carotid artery pulsation. B wave, the initial positive deflection in the electroretinogram, possibly arising from the inner nuclear layer of the retina. (05 Mar 2000) |
| arterio-arterial fistula | Abnormal communication between two arteries. It may result from injury or occur as a congenital abnormality. (12 Dec 1998) |

| pancreaticoduodenal arterial arcades | Anastomoses between the anterior and posterior pancreaticoduodenal arteries (from the gastroduodenal artery) and the anterior and posterior inferior pancreaticoduodenal arteries (from the superior mesenteric artery) on the anterior and posterior aspects of the head of the pancreas and the duodenum, supplying both structures. (05 Mar 2000) |
| mean arterial pressure | <cardiology, physiology> The average value for arterial pressure. Systolic pressure + diastolic pressure divided by 2. (27 Sep 1997) |

| plantar arterial arch | The arterial arch formed by the lateral plantar artery running across the bases of the metatarsal bones and anastomosing with the dorsal pedis artery, either of two bony arch's of the foot, longitudinal arch or transverse arch. See: medial longitudinal arch of foot, lateral longitudinal arch of foot, transverse arch of foot. Synonym: arcus plantaris, plantar arterial arch. (05 Mar 2000) |
