Abstract

Venous thromboembolism (VTE) is the condition in which blood clots form within the venous circulatory system, and consist of DVT (deep vein thrombosis) and PEs (Pulmonary emboli). It is a common condition, with an estimated life-time risk of 8% and an annual incidence of 0.84-1 per 1000 population1, 2 and represents a significant economic burden: within Australia the annual estimated cost in 2018 being $1.72 billion AUD3. The condition is considered aeromedically significant for both aircrew and passengers; diagnosis and treatment may have implications on an aviators medical certificate and the general public are often concerned about developing “economy class syndrome”. This paper reviews the pathophysiology of VTE, the relationship between VTE and its treatment in the aviation environment. It also reviews some of the international aeromedical regulatory guidelines and provides a suggested approach to certification in case of VTE.
