DISEASES OF THE VEINS AND ARTERIES. 



INFLAMMATION OF THE JUGULAR VEIN. 



This occurs as a sequel to bleeding. It is characterized by a 

 reddening of all its coats, an exudation ponrs out from the coats 

 of the vein, which along with its contents forms a solid coaguliim 

 or clot. At first the clot is but loosely attached to the interior 

 of the vessel, but soon it becomes more strongly adherent, the 

 surrounding areolar tissue is infiltrated with serum, and that in 

 contact with the vein, adherent to it, by a fibrinous exudate. 

 Generally a swelling appears along the course of the coagulum, 

 in which fluctuation can be detected similar to any other abscess. 

 The pus is confined above and below by the coaguliuu. If the 

 vein is manipulated on its course towards the head, it will be 

 found to be considerably thickened. The swelling extends to- 

 wards the head. 



Tkeatment. — Apply a cantharides blister to the part. If ab- 

 scesses have formed, they must be opened before the blister is 

 applied. Inflammation of the jugular always terminates in the 

 permanent closure of the vessel. 



THROMBUS. 



This disease is produced through improper closure of the 

 wound after Ideeding. 



Symptoms. — Swelling in the noighl)orhood of the wound. The 

 swelling is caused by the exudation of a small amount of blood 

 into the areolar tissue. The exudation is from the jugular vein, 

 and takes place in about twenty-four hours after the operation. 



Treatment. — Tie tlio head to the rack, and apply a sponge 

 saturated with cold water to the parts.
