Summary
Double-velour woven Dacron prostheses were investigated both experimentally and clinically.
In 6 mongrel dogs, a tandem conduit between the right ventricle and the pulmonary
artery was implanted, consisting of a plain woven and a double-velour woven graft.
Following explanation after 2, 4, and 6 months, superior healing properties of the
doublevelour woven prostheses could be assessed by microscopy, as represented by an
increase of tissue ingrowth, as well as by a thin and densely adherent inner healing
capsule. Double-velour woven grafts were implanted in 50 patients undergoing open
heart surgery. All grafts were presealed with fibrin glue and no bleeding could be
detected at the time of implantation, even under the adverse influence of full heparinization
and extracorporeal circulation.
