VARICOSE See also:

VEINS (See also:Lat. varix, a dilated vein)  , a See also:condition of the See also:veins which mostly occurs in those parts of the See also:blood-stream which are farthest from the See also:heart and occupy a de-pendent position . Thus they are found in the legs and thighs; in the lowest See also:part of the bowel (piles; see See also:HAEMORRHOIDS), and in the spermatic See also:cord (varicocele) . Any condition which hinders the return of blood from the veins is See also:apt to cause their permanent See also:dilatation; thus is explained the occurrence of varicose B B' veins in the See also:leg from the wearing of a tight garter, and of piles as the result of the pressure of an ovarian See also:tumour or of a pregnant uterus, or of disease of the See also:liver . Sometimes the trouble is begun by a See also:direct injury to the vein, which, by setting up an inflammation, weakens the coats of the vein, which then yield under the pressure of the blood-stream . In the See also:case of varicocele, the dilatation of the veins is probably of developmental origin; many other causes are given, but not one of them appears satisfactory . Examination of a varicose vein shows that it is increased in length as well as in capacity . In some parts of its course the vein has its coats much thickened, but at those places where there is most dilatation the walls are very thin . Veins thus affected give rise to pains and achings, and they are, moreover, liable to attacks of inflammation which end in clotting of the blood (thrombosis) . This is a dangerous condition, as a sudden or violent See also:movement is apt to cause the detachment of a piece of the See also:clot, which, carried up to the See also:brain or the See also:lung, may cause sudden See also:death . Less serious results of varicose veins are swelling of the parts below (oedema), ulceration and See also:abscess . As regards treatment, the wearing of a well-fitting elastic See also:stocking will prove beneficial in the case of a moderate dilatation of the veins of the leg; the individual must avoid See also:long See also:standing and fatigue . It is well also to have the See also:foot of the See also:bed raised three or four inches, so that during the See also:night the veins may be kept as empty as possible .

If the case is more serious, the thinned veins threatening to give way, it will be advisable, provided the dilatations are fairly well localized, and the See also:

general condition of the patient permits, to See also:excise the diseased parts, tying the cut ends of the veins, and closing the See also:surface wounds with See also:fine sutures . Should a varicose vein be plugged with clot, it will be advisable to tie it high up where the coats are healthy, and to remove the See also:lower part by See also:dissection . This will render the See also:person safe from the very serious See also:risk of a piece of the clot being carried to the heart, and will also permanently rid him of his trouble . It may be said generally that any operative treatment for varicose veins in the lower extremity is best associated with the application of a ligature upon the large surface vein just before it enters the See also:common femoral vein below the See also:fold of the See also:groin . This operation removes the risk of the downward pressure of blood in the veins whose dilatation has rendered the valves useless . In the case of a varicose vein being opened by See also:accident or disease, it is quite possible for the individual to bleed to death . The first-aid treatment for the serious See also:haemorrhage should consist in laying the patient on the See also:floor, raising the See also:limb upon the seat of a See also:chair, and fixing a See also:pad over the open See also:vessel by a handkerchief or bandage . Varicose veins of the spermatic cord (varicocele) of the See also:left See also:side are met with in adolescents . The dilatation is, in all See also:probability, of developmental origin, making its See also:appearance at See also:puberty . It is, as a See also:rule, of no serious moment, and, unless See also:present in an extreme degree, had best be treated merely by a suspension bandage . If, however, it is causing real See also:physical See also:distress, it may be treated by excision of an See also:inch or two of the bunch of dilated veins . The presence of varicocele is apt to cause inconvenience or even discomfort to men living in See also:India or the tropics, but the Englishman who intends spending his See also:life in temperate climes will do well to ignore a varicocele .

It will become less and less noticeable as See also:
