title: Arteriovenous intestinal communications in shock. Experimental study using tagged microspheres.
abstract: Microspheres 25 plus or minus 5 microns in diameter labeled with Ce141 and Sr85 were used to study the influence of oligemic shock on any arteriovenous anastomoses of the small intestine mucosa of dogs and rabbits. We found no open AVA's larger than 20 microns in diameter either before or during oligemic shock.
