@gently This is what I was looking for. Thank you... The following is from Robert Chang's studies: Although we cannot confirm the reasons for disparities in AAA repair in men and women, it may be related to women having an anatomy unsuitable for endovascular repair. These patients did not, however, have higher rates of comorbid conditions compared with those with timely repair. Most of these patients were delayed because of a discrepancy in size between the radiologist and the vascular surgeon. Unfortunately, the scope of this project did not allow deeper analysis of these size discrepancies. Better understanding and addressing reasons for delayed repair represents an important area for improvement, as our data demonstrate that delaying elective repair in patients with aneurysms $5.0 cm in women and $5.5 cm in men seems to have deleterious consequences.
