■1118 Rupture of the Large Blood Vessels. 



bifurcation. — Ehlers observed rupture of the portal vein after a blow on the left 

 side of the body.-^SchruUe reports a case of fatal hemorrhage from rupture of 

 the left axillary artery in a iiorse which had been thrown. On autopsy of a 

 horse Biihrmann found an abscess between the pillars of the diaphragm, which 

 had ruptured into the aorta. — In Gassner's case an exostosis on the 16th vertebra 

 had injured the aortic wall, in Noack's case a sarcoma growing behind the kidney 

 had done the same. Parasites may also be involved. Morgagni .found in one 

 dog, Megnin in three dogs, the Spiroptera sanguinolenta in the wall of the aorta; 

 it was present in the form of small whitish nodes one of which had caused rupture 

 of the aorta. Durieux and Degive finally could demonstrate in a horse that fatal 

 hemorrhage had been due to destruction of tissue by the larvae of the Sclerostomum 

 vulgare (in one case the aorta was apparently sound, in the other it presented 

 in its entire length the picture of atheromatosis). 



The symptoms of rupture of a vessel indicate in general 

 only internal hemorrhage, the exact cause of which can usually 

 only be ascertained on autopsy.
