CHAPTER VI. 



DISEASES OF BLOOD-YESSELS AJSTD LYM- 

 PHATICS. 



Wounds of arteries — punctured, cut, torn. Arteritis, inflammation of ar- 

 teries. Embolism, plugging. Aneurism, dilatation. Wounds of veins. 

 Phlebitis, inflammation of veins — circumscribed, diffuse. Varicose — dilated 

 veins. Lymphangitis, inflammation of lymphatics. Weed. Poisoned and 

 irritated wounds. 



DISEASES OF ARTERIES. 

 ■WOUNDS OP ABTERIES. 



Punctured loounds are rarely dangerous, as the waUa 

 quickly close, and the few drops of blood which escape 

 help to i>lug the orifice ; but there is danger of inflamma- 

 tion and plugging of the vessel, and cold or warm fomen- 

 tations with rest are desirable. 



Gut loounds, if only implicatiug the outer coats, soon 

 ■heal and are rarely followed by dilatations as in man. If 

 all the thickness of the wall is incised the result will be 

 according to the direction. If in a line with the course of 

 the vessel there is little risk and shght pressure will usu- 

 ally check bleeding. If transverse or obhque the elastic- 

 ity of the waUs of the vessel holds the orifice open and 

 bleeding is severe, the blood flowing in. jets and of a bright 

 rod color. If cut completely across, the arterial coats re- 

 tract and curl within themselves and in small vessels will 

 often close the opening. 



To check Ueeding the end of the vessel may be sought 

 and tied, or a piece of silver wire may be passed through 

 to the soft parts beneath it by the aid of a curved needle.
