DISEASES OF ARTERIES. 

 WOUNDS OF ARTERIES. 



Pttndnred wounds are rarely dangerous, as the walls quickly 

 close and the few drops of blood which escape help to plug the 

 orifice ; but there is danger of inflammation and plugging of the 

 vessel, and cold or warm fomentations with rest are desirable. 



Cut wounds^ if only implicating the outer coats, soon heal 

 ar.d are rarely followed by dilatations as in man. If all the 

 thickness of the wall is incised the result will be according to 

 tlie direction. If in a line with the course of the vessel there 

 is little risk, and slight pressure will usually check bleeding. If 

 Uunsverse or oblique the elasticity of the walls of the vessel

 I'l jets and of a bright red colour. If cut completely across, 

 I lie arterial coats retract and curl within themselves, and in 

 small vessels will often close the opening. 



To check bleeding the end of the vessel may be sought and

 soft parts beneath it by the aid of a curved needle, and tied 

 over a cork placed on the surface of the skin. It may be un- 

 twisted and drawn out in twenty-four hours. Or a pad of tovy
