| intra- | Inside, within; opposite of extra-. See: endo-, ento-. Origin: L. Within (05 Mar 2000) |
| intra-abdominal | Within the abdomen. (05 Mar 2000) |
| intra-abdominal abscess | <surgery> A localised pus-forming (suppurative) bacterial infection that occurs within the abdominal cavity as the result of a perforated viscus or post operative complication. Treatment requires either percutaneous or open surgical drainage. (27 Sep 1997) |
| intra-abdominal calcifications | <radiology> Urinary, kidneys, ureters, prostate, seminal vesicles, biliary, gallstones (15% radiopaque), milk of calcium bile, porcelain gall bladder, pancreatic, vascular, lymph nodes, neoplastic, psammomatous calcification (especially mucinous adenocarcinoma), miscellaneous, appendiceal mucocele, appendicolith, ovarian teratoma, haematoma, injection granuloma (12 Dec 1998) |
| intra-acinous | Within an acinus. (05 Mar 2000) |
| intra-adenoidal | Within the adenoids. (05 Mar 2000) |
| intra-alveolar septa | The bony partitions that project into the alveoli between the roots of the molar teeth. Synonym: septa interradicularia, intra-alveolar septa. (05 Mar 2000) |
| intra-aortic balloon | An externally and intermittently inflatable balloon placed into the descending aorta and which, on activation during diastole, augments blood pressure and organ perfusion by its pulsatile thrust; then, on deflation, decreases the cardiac work with each systole-the so-called counterpulsation principle-by reducing cardiac afterload. (05 Mar 2000) |
| intra-aortic balloon pump | <cardiology, equipment> A device which is threaded into the aorta that augments the strength of the hearts contraction. The counter pulsation, produced by the inflation of a balloon within the aorta, provides an rhythmic increase in aortic pressures. The net effect is an increase in coronary artery blood flow. Intra-aortic balloon pump is a temporary lifesaving measure that is used to treat severe cardiac damage due to a massive heart attack. (27 Sep 1997) |
| intra-aortic balloon pumping | Counterpulsation in which a pumping unit synchronised with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates, it raises aortic diastolic pressure, and as it deflates, it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion. (12 Dec 1998) |
| 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) |
| intra-articular | Within the cavity of a joint. Origin: intra-+ L. Articulus, joint (05 Mar 2000) |
| intra-articular cartilage | A plate or ring of fibrocartilage attached to the joint capsule and separating the articular surfaces of the bones for a varying distance, sometimes completely; it serves to adapt two articular surfaces that are not entirely congruent. Synonym: discus articularis, articular disk, fibrocartilago interarticularis, fibroplate, interarticular fibrocartilage, intra-articular cartilage. (05 Mar 2000) |
