| digital subtraction angiography | Computer-assisted roentgenographic angiography permitting visualization of vascular structures without superimposed bone and soft tissue density; images made before and after contrast injection allow subtraction (separation and removal) of opacities not enhanced by the contrast medium. Other image-processing can be performed. Contrast material may be injected intravenously or in lower-than-usual amount intra-arterially. (05 Mar 2000) |

| infantile digital fibromatosis | Multiple fibrous flesh-coloured nodules on the extensor aspect of the terminal phalanges of adjacent digits of infants and young children which often recur after attempted excision, do not metastasize, and may spontaneously regress in two to three years; composed of spindle cells containing cytoplasmic inclusions believed to be derived from myofibrils. Synonym: infantile digital fibromatosis. (05 Mar 2000) |
| tendinous chiasm of the digital tendons | Crossing of the tendons, the passage of the tendons of the flexor digitorum profundus (flexor digitorum longus in the foot) through the interval left by the decussation of the fibres of the tendons of the flexor digitorum superficialis (flexor digitorum brevis in the foot). Synonym: chiasma tendinum, Camper's chiasm. (05 Mar 2000) |
| extensor digital expansion | A triangular tendinous aponeurosis including the tendon of the extensor digitorum centrally, interosseus tendons on each side, and a lumbrical tendon laterally. It covers the dorsal aspect of the metacarpophalangeal joint and the proximal phalanx. Synonym: dorsal hood, extensor aponeurosis, extensor expansion. (05 Mar 2000) |
| fibrous digital sheaths of foot | Fibrous sheaths of the toes, the tubular fibrous layer enclosing the synovial sheath and the tendons of the long and short flexors of the toes and the flexor hallucis longus in the digits; they are composed of annular and cruciform parts. Synonym: vaginae fibrosae digitorum pedis. (05 Mar 2000) |
| fibrous digital sheaths of hand | Fibrous sheaths of the digits of the hand, the tubular fibrous layers that enclose the synovial sheaths and the superficial and deep flexor tendons and the tendon of the flexor pollicis longus in their passage along their respective digits; they are composed of annular and cruciform parts. Synonym: vaginae fibrosae digitorum manus. (05 Mar 2000) |
| alveolocapillary block | The presence of material that impairs the diffusion of gases between the air in the alveolar spaces and the blood in alveolar capillaries; block can be caused by oedema, cellular infiltration, fibrosis, or tumour, and results in undersaturation of peripheral arterial blood with oxygen.
