Abstract
An intravascular foreign material was seen in tissue sections of human beings dying after experiencing cardiotomy and extracorporeal perfusion in which dimethylpolysiloxane (Dow-Corning Antifoam A) was used as a defoaming agent. The material is similar in appearance to emboli demonstrated in a dog receiving Antifoam A intra-arterially.
