DISEASES AND TREATMENT OF THE HORSE 26f, 



II. — Diseases of the Arteries. 



3. Tumor (Aneurism). 



This is a diseased state of the walls of an artery. 



Causes. — The causes are unknown. 



Symptoms. — Tumor may be present for some time before 

 being detected, in fact until the artery gives way at the point 

 of attack. Should this occur internally and the artery be 

 large, death soon follows from loss of blood. Should it occur 

 in a small artery among the muscles death will not follow 

 from loss of blood, because of the stoppage of bleeding by 

 clotting, and pressure of the skin and muscle. This condition 

 may be detected by a swelling suddenly appearing in the 

 vicinity of the diseased artery. There may be weakness of 

 course accompany the rupture according to its extent. Pres- 

 sure upon the swelling will indicate the presence of the fluid 

 within. 



Treatment. — Allow the fluid to remain in the swelling 

 two or three days until positive that the artery has stopped 

 bleeding; then, with a sharp knife, open into the lower part 

 of the swelling — make a large cut — and remove all the clotted 

 blood ; then, with a large syringe, wash out all the blood with 

 lukewarm water containing a few drops of carbolic acid. 

 After this, bathe the parts well with lukewarm water twice a 

 day, and inject the white lotion each time, after bathing. 

 Keep the animal quiet and it heals in the course of two or 

 three weeks. Should bleeding of the artery occur the second 

 time, it may be necessary to tie it above the point of rupture 

 with a piece of strong cord. 



4. Rupture of an Artery. 



Causes. — It is sometimes caused by straining while foal- 

 ing, drawing heavily, severe exertion of any kind, or a severe 

 bruise. 



Symptoms. — These are the same as those of tumor or 

 aneurism of an artery, only the artery is not diseased. 



Treatment. — Treat in the same manner as a tumor or 

 aneurism of an artery.
