The presentation and prognosis of venous thromboembolism (VTE) are known to be characterized by considerable sex differences. While men and women have a similar overall risk of developing a first acute VTE [1,2], the incidence of VTE differs between sexes within specific age groups: women have an increased VTE risk in their childbearing age, whereas men are at an increased risk when their age increases [3]. Several reports found that pulmonary embolism is a more frequent presentation site than deep venous thrombosis in women, but not in men [4].
