Reproductive history in women with lower limb ischemia.

The purpose of this study was to identify reproductive factors that may contribute to the development of arteriosclerosis in the leg arteries by comparing the reproductive history of women with lower limb ischemia to a reference group of women. All 173 female patients treated for chronic lower limb ischemia with surgical or endovascular procedures performed from 1994 to 1996 at a university clinic received a validated questionnaire to which 116 (67%) responded. The reference group, 348 women, 197 (57%) of whom responded, was recruited randomly from the hospital catchment area. The 2 groups were similar regarding age at menopause and menarche, pregnancies, salpingo-oophorectomies, and hormone replacement therapy. There was a higher number of women who had used oral contraceptives in the reference group than in the patient group (53% vs 16%, p < 0.001). The same results were found when comparing the subgroup of patients younger than 55 years to the references. No association between reproductive history and development of lower limb ischemia could be found. Our results support that use of oral contraceptives early in life is not associated with an increased risk for lower limb ischemia.
