Baboon (Papio ursinus) model to study deep vein thrombosis using 111-indium-labeled autologous platelets

This study evaluates the chacma baboon as a model for investigations on deep vein thrombosis (DVT). There is a good correlation of the baboon and human thrombelastographic parameters (r-time, k-time, ma). Investigation on the diagnostic efficacy of 111 In-labeled platelets as an imaging agent for DVT cast considerable doubt on the procedure, owing to the age of the thrombus.
