ANGEIOMA. CIRCOID ANEURISM. ANEURISM BY ANASTOMOSIS. VENOUS TUMOR. NŒVUS.
These are forms of dilatation and elongation of the network of small arteries, or veins, and even of the intervening capillaries. In man these constitute the unsightly red patches and swellings that appear on the face and hands. In animals with dark skins and hairy covering they can only be recognized by the swelling, the feeling as of a bag of worms when the hand is passed over it, and by the rushing sound when auscultated. The trouble is usually subcutaneous and is essentially a surgical one. The most promising treatment is by persistent pressure, by electric current supplementing the pressure, by electro-puncture, and by injections of muriate of iron. When the nœvus is not too extensive a double thread drawn by a needle through beneath the tumor at short intervals, then cut and each point tied separately, so as to completely stop circulation is most effective.
