Treatment guidelines recommend that an abdominal aortic aneurysm in men should be considered for elective repair once the aneurysm has reached a diameter of 5·5 cm, based on randomised trials that compared early elective repair with surveillance; these trials included only a small proportion of women.1 The decision to offer repair is made when the probable risk of rupture exceeds the risk of repair. Since the rate of rupture of small abdominal aortic aneurysm is four times higher in women than men at the same diameter,2 women are often considered for repair at diameters smaller than 5·5 cm. Several studies3, 4 have suggested that the prognosis of individuals with abdominal aortic aneurysm…………continue reading
