Thrombosis of the arteria coeliaca. Thrombosis of the arteria 



coeliaca (see page 395), which is extremely rare, like thrombosis of the 

 anterior mesenteric artery, does not usually produce any disturb- 

 ances in general health. A case described by Friedberger (Z. f. pr. 

 Vet.-Wiss. 1875, 258) shows, however, that such a thrombosis may 

 also cause symptoms of disease. The celiac artery in the case referred 

 to contained two half cylindrical thrombi 17 and 25 mm. wide, the cen- 

 tral end of the thicker thrombus was free in the trunk of the art. 

 coeliaca. After motion the horse presented symptoms of severe colic 

 and from time to time made peculiar noises such as are heard when 

 horses are vomiting; it was also attacked at times by tonic convulsions. 

 These attacks could be produced at will whenever the animal was made 

 to move. Eleven days after the last attack the animal was killed and 

 the postmortem examination showed a bro^^^l red discoloration of the 

 gastric mucosa at the pyloric portion and signs of older hemorrhages 

 in it, strong injection of blood vessels of the submucosa and hyperemia 

 and hemorrhages in the first portion of the duodenum. The symptoms 

 observed during the disease of the animal were believed to be due to a 

 simultaneous aneurysm of the abdominal aorta, causing hyperemia of 

 the brain or an accumulation of carbon-dioxide in the central nervous 

 system; however, the symptoms were so similar to those observed by 

 Marek on experiment dogs after ligation or obstruction of the art. 

 coeliaca or some of its branches, that they may easily be associated with 

 thrombosis of the celiac arterv as it existed in this horse. 



Thrombosis of Mesenteric Veins. Throml)osis of l)ranches of the 

 portal vein or of this vein itself has repeatedly been seen in domestic 

 animals. Thrombosis of the portal vein is not uncommon in cattle and 

 is caused by pressure of tuberculous masses or it may be due to injury 

 by foreign bodies. Gohre and Spann have likeunse observed thrombosis 

 of the portal vein in cattle. Goubeaux, Collin, Mollereau, Cabaret, Kitt, 

 Gratia have seen thrombosis of the portal vein of the horse ; Connochic, 

 a thrombosis of the anterior mesenteric vein; Siedamgrotzky, a throm- 

 bosis of both veins of the colon; in a case of Barrier there was com- 

 pression of the portal vein by a carcinoma of the stomach. The authors 

 saw a case in a dog where the large veins of the mesentery were com- 

 pressed by a tumor of the mesentery. Thrombosis of the mesenteric 

 veins is not rare in deeper inflammations or ulcerations in the intestines 

 (Kitt) and it is possible that coagulation of the blood in the veins may 

 occasionally be caused by thrombosis of the mesenteric arteries. 



Symptoms of disease are produced only liy thrombosis or compres-
