Piirideiit hifectioii of the Navel 



1015 



Passing through the puhnouary capillaries, and reaching the 

 systemic circulation, the infection may become arrested at any 

 point, and induce an acute septic or pyaemic inflammation. The 

 infection is especially liable to become lodged in the capillaries 

 in or about the synovial membranes of the articulations or of 

 the sheaths of tendons, and to induce therein either an acute 

 serous or purulent inflammation.

No tissue or organ of the body is immune against the ravages 

 of the disease. The internal organs are by no means free from 

 the dangers of pysemic infection. Abscesses of the liver, kid- 

 neys and spleen are frequently found. 



We have frequently observed absces.ses within the umbilic 

 veins and arteries, as shown in Fig. 146, especially when these 

 vessels have been caught and held as a consequence of the 

 ligation of the umbilic cord. If the cord has not been ligated, 

 and the arteries thus* held, they quickly retract into the abdomen 

 and are comparatively free from danger.
