Anatomical differences could make aneurysm repair more difficult in women

February 4, 2008 Anatomical differences could make aneurysm repair more difficult in women Sarah Jersild -------------------------------------------------------------------------------- Endovascular aneurysm repair to treat abdominal aortic aneurysm tends to be more challenging in women than in men due to anatomical differences, according to a study presented at the International Symposium on Endovascular Therapy held last month in Florida. Abdominal arteries and the proximal landing zones used to anchor intravascular stents for AAA repair tend to be smaller in female patients, said Dr. Mei Nortley, a vascular surgeon and research fellow at St. Mary's Hospital in London. The study of 35 women and 150 men found that the blood vessels used to access the aorta had a mean measurement of 7.4 mm in women, compared with 9.1 mm in men. In many cases, EVAR devices may be too large to easily pass through the smaller artery.
