Abstract
Experimental evaluation of a new type of dacron graft, pretreated with mod ified mammalian gelatin, has been performed on the beagle dog. After grafting of the infrarenal aorta, dogs were monitored from three days to three months. Pretreatment with gelatin effectively avoided the need for preclotting and did not affect the normal healing of the prosthesis as compared with similarly tex tured not pretreated grafts. This graft, when applied in man as an abdominal aortic substitute, has yielded uniformly gratifying results (within a follow-up range of twenty to twenty-seven months).
