VARICES. 367" 
' ‘puration is limited to a small distance in the vein; it is: insufficient when: 
the phlebitis is old, when the vascular walls are infiltrated with pus, and. 
the abscesses are developed in the perivenous structures. The vein must . 
be drained in its suppurating portion. After making a counter opening. 
on a level with the intravenous fistula, a fenestrated rubber tube is in- 
troduced in the tract to insure the escape of pus and allow the cleaning 
of the vein. We.will return to this, in the article on suppurative phlebitis... 
of the jugular. 
Another treatment consists in cutting down in its whole length the. 
portion of the fistulous vein and treating the part exposed. Like Hoff- 
man, it is better, after exposing the vein in all its suppurating portions, to. 
clean it by curetting; to leave no diseased point in the neighborhood of © 
the clot, clean the operated surface with a strong antiseptic solution and. 
dress with iodoform. In the legs the curetting can be completed with . 
antiseptic baths; for the other regions, sprays are indicated. Between 
. these the wound will be protected with compresses dipped in microbicide. - 
solution, or with. antiseptic vaseline. : 
Ligature and extirpation are means which to-day are little used. In 
some serious cases where free incision is dangerous, cauterizations with 
fine points or with needles, of the suppurating venous portion, has brought : 
on recovery. 
Hemorrhagic phiebitis, complication of the adhesive and suppurative. 
forms, due to the loosening, crushing, purulent destruction of the obliter- 
ating clot, is treated by plugging of the wound, suture of its borders or 
. ligature of the vein. This last operation must be done antiseptically on a 
sound part of the vessel and beyond the induration. Layer by layer the - 
- tissues covering the vein are excised, the vessel is isolated and surrounded. . 
with an aseptic silk thread tied with a straight knot. The wound is. 
irrigated with boiled water, is dried, dusted with iodoform, the edges. 
brought together by two or three stitches, the whole covered with a col-- 
lodion dressing. As for the fistula and the suppurating portion of the . 
vessel, they demand the same care as indicated for adhesive phlebitis...

VARICES. 
Generally speaking, permanent dilatations of veins, varices or phiebee~- 
fasts, are rare in all animal species. 
They occur most commonly on the veins of extremities, or those of the: 
organs where the venous current has an ascending direction. In horses,.. 
they have been observed on the radial, saphena, axillary and testicular ;.;
