[Paget-Schroetter syndrome caused by wrestling]

Upper extremity thrombosis (Paget-Schroetter syndrome) hints already at physical strains with regard to the synonymous term "effort thrombosis". We report two cases of upper extremity thrombosis caused by wrestling. Wrestling as an example of martial arts activity leads to traumatic venous intima lesions with resulting local activation of coagulation as a main reason in pathogenesis of these thromboses. The possibility of a Paget-Schroetter syndrome should be considered in differential diagnosis if upper extremity complaints of unknown origin occur after wrestling matches. This kind of subclavian vein thrombosis should be reported to the accident insurance.
