| pedicle | 1. A constricted portion or stalk. Synonym: pediculus. 2. A stalk by which a nonsessile tumour is attached to normal tissue. Synonym: pedunculus, peduncle. 3. A stalk through which a flap receives nourishment until its transfer to another site results in the nourishment coming from that site. Origin: L. Pediculus, dim. Of pes, foot (05 Mar 2000) |
| pedicle flap | A skin flap sustained by a blood-carrying stem from the donor site during transfer, in periodontal surgery, a flap used to increase the width of attached gingiva, or to cover a root surface, by moving the attached gingiva, which remains joined at one side, to an adjacent position and suturing the free end. (05 Mar 2000) |
| pedicle graft | A skin flap sustained by a blood-carrying stem from the donor site during transfer, in periodontal surgery, a flap used to increase the width of attached gingiva, or to cover a root surface, by moving the attached gingiva, which remains joined at one side, to an adjacent position and suturing the free end. (05 Mar 2000) |
| pedicle of arch of vertebra | The constricted portion of the arch on either side extending from the body to the lamina; bound intervertebral foramina superiorly and inferiorly. Synonym: pediculus arcus vertebrae, radix arcus vertebrae. (05 Mar 2000) |
| permanent pedicle flap | A pedicle flap in which the pedicle is not severed at the time of transfer, so that it continues to supply blood from the donor site to the recipient area. (05 Mar 2000) |
| double pedicle flap | A flap with two pedicles, one at each end. Synonym: double pedicle flap. (05 Mar 2000) |
| tubed pedicle flap | A flap in which the sides of the pedicle are sutured together to create a tube, with the entire surface covered by skin. Synonym: Filatov flap, Filatov-Gillies flap, Filatov-Gillies tubed pedicle, rope flap, tubed pedicle flap. (05 Mar 2000) |
| Filatov-Gillies tubed pedicle | A flap in which the sides of the pedicle are sutured together to create a tube, with the entire surface covered by skin. Synonym: Filatov flap, Filatov-Gillies flap, Filatov-Gillies tubed pedicle, rope flap, tubed pedicle flap. (05 Mar 2000) |
| air-conditioner lung | An extrinsic allergic alveolitis caused by forced air contaminated by thermophilic actinomycetes and other organisms. (05 Mar 2000) |
| airless lung | <radiology> Tumour, foreign body, mucous plug (12 Dec 1998) |
| anterior border of lung | The thin anteromedial or sternal edge of the lung which overlaps the pericardial sac anteriorly and forms the boundary between the mediastinal and costal surfaces. Synonym: margo anterior pulmonis. (05 Mar 2000) |
| apex of lung | The rounded, upper extremity of each lung that extends into the cupula of the pleura. Synonym: apex pulmonis. (05 Mar 2000) |
| apical interstitial lung disease | <radiology> A radiological diagnosis where fibrosis is seen in the apices (upper sections) of the lungs. Likely causes include: cystic fibrosis, ankylosing spondylitis, sarcoidosis, silicosis, eosinophlic granuloma, TB and fungus, particularly aspergillus infection. (25 Jun 1999) |
| asbestos lung disease | <radiology> Pleural plaques, earliest finding, may be only evidence, parietal pleura, 15-20 yrs after exposure, calcified after ca. 30 yrs, asbestosis, interstitial lung disease, perihilar regions to lung bases, shaggy heart, no cavitation or progressive massive fibrosis as in silicosis, crocidolite (blue) form most carcinogenic, associated with: malignant pleural mesothelioma, peritoneal mesothelioma, GI-tract malignancy (12 Dec 1998) |
