Activated protein C resistance as a "new" cause of deep venous thrombosis in aviators.
Aviators are occasionally diagnosed as suffering from deep venous thrombosis (DVT). Despite the recognition of the "Economy Class Syndrome" in the 1960's, the relationship between DVT and aviation is not clear cut. A case of DVT is described in a military navigator who was also found to be a heterozygote for activated protein C resistance. This case highlights the importance of considering all components of Virchow's triad when assessing the significance and management of DVTs. Aspects of the Economy Class Syndrome and of activated protein C resistance are discussed.
