VARICOSE VEINS (Varix)
Categories:
Circulatory System
This term means an enlarged, elongated, tortuous,
knotty condition of the veins. The term "varicose veins" is restricted in
general use to the veins of the extremities, and especially those
belonging to the lower extremity. The disease begins with a slow dilation
of the vein, which gradually becomes thickened and tortuous. The inner
lining membrane or coat of the vein is altered, the valves are shortened
and thus rendered insufficient to support the column of blood. The outer
coat becomes thickened. The varicose conditions affect chiefly the
superficial veins.
Predisposing Causes. They are most frequent in the female sex. The
tendency increases as the age advances. Obstruction. Anything that
obstructs the full return of blood in the veins, as tight garters below
the knee, etc. Standing work may bring it on.
Exciting Causes. Tumors in the pelvis; diseases of the heart and lungs;
pregnancy. These all obstruct the full return of blood in the veins.
