title: A comparison of the behaviour of autologous and homologous platelets in microporous polyurethane grafts. An experimental study in sheep.
abstract: In experimental studies in sheep the behaviour of autologous and homologous platelets in microporous polyurethane grafts was compared at a flow rate of 25 ml/min. The grafts were interposed to replace segments of resected carotid arteries. The deposition of 32P-labelled platelets on the graft wall was recorded, as were graft patency, thrombus weight and thrombus-free surface. Compared to autologous platelets, homologous platelets accumulated over longer periods of time and in greater numbers, leading to deposition of larger amounts of thrombus material and reduced patency.
