varicophlebitis (var"i-ko-fle-bi tis) [" +  Gr. phleps, vein,    +    itis, inflammation]. Phlebitis combined with varicose veins.
varicose (var'i-kos) [L. varicosus, full of dilated veins]. Pert. to varices; distended, swollen, knotted veins.
varicose ulcers.  Ulcers that form as a result of varicose veins. When thrombophlebitis develops in varicose veins, this leads to venous stasis and eventually edema and ulcer formation.
NURSING IMPLICATIONS: Maintain patient on bedrest. Continuously apply warm, moist compresses to relieve discomfort and infection. Use aseptic technique when applying dressings and therapeutic agents. varicose veins. Enlarged, twisted superficial veins. May occur in almost any part of the body but are most commonly observed in the lower extremity and in the esophagus.
SYM: Pain in feet and ankles, swelling, ulcers on skin. Severe bleeding if a vein is injured.
ETIOL: Incompetent venous valves that may be acquired or congenital. The development of varicose veins is promoted and aggravated by pregnancy, obesity, and occupations that require prolonged standing. Esophageal varices are caused by portal hypertension that accompanies cirrhosis of the liver.
F.A.: In hemorrhage, elevation of extremity and gentle but firm pressure over wound will stop bleeding. The use of a tourniquet is undesirable. Sterile dressing should be held in place with a firm bandage. Patient should not be permitted to walk for some time. The Sengstaken-Blakemore tube may be used to control bleeding due to hemorrhage from esophageal varices.
TREAT: In general, consists of rest, elevation of extremity, and use of an external support. The use of elastic stockings is much preferred to elastic bandages. Unna's paste boots recommended for elderly or debilitated persons. Injection of sclerosing solutions may be utilized for small varicosities. High ligation and removal of vein by stripping may be necessary for major varicosities.
varicosis (var"i-ko'sis) [L.]. Varicose condition of veins.

varicosity
(var"i-kos'i-te) [L. uarix, twisted vein]. 1. Condition of being varicose. 2. A swollen, twisted vein. SYN: varix.

vertebra
(ver'te-bra) [L.]. (pl. vertebrae) [NA] Any one of the 33 bony segments of the spinal column. The spinal vertebrae contain 7 cervical, 12 thoracic (dorsal), 5 lumbar, 5 sacral, and 4 coccygeal vertebrae. In adults, the five sacral vertebrae fuse to form a single bone, the sacrum, and the four rudimentary coccygeal vertebrae fuse to form the coccyx.
A typical vertebra consists of a ventral body and a dorsal or neural arch. In the thoracic region the body bears on each side two costal pits for reception of the head of the rib. The arch that encloses the vertebral foramen is formed of two roots or pedicles and two laminae. The arch bears seven processes: a dorsal spinous process, two lateral transverse processes, and four articular processes (two superior and two inferior). A deep concavity, inferior vertebral notch, on the inferior border of the arch provides a passageway for a spinal nerve. The successive vertebral foramina surround the spinal cord.
The bodies of successive vertebrae articulate with one another and are separated by intervertebral disks, disks of fibrous cartilage enclosing a central mass, the nucleus pulposus. The inferior articular processes articulate with the superior articular processes of the next succeeding vertebra in the caudal direction. Several ligaments (supraspinous, interspinous, anterior and posterior longitudinal, and the ligamenta flava) hold the vertebrae in position yet permit a limited degree of movement.
v., basilar. The lowest of the lumbar vertebrae.
v., cervical. The seven vertebrae of the neck.
