Why the study?
Does pregnancy alter the thickness of the carotid artery wall layers compared to fertile non-pregnant women?
Does pregnancy alter the thickness of the carotid artery wall layers compared to fertile non-pregnant women?
High-frequency ultrasound detects significant differences in carotid artery wall layer thickness between pregnant and non-pregnant women, potentially reflecting hormonal effects.

Hypothesis-generating carotid wall changes in pregnancy require longitudinal confirmation; does not yet alter clinical practice.
OBJECTIVE: To compare the thickness of the layers of the carotid artery wall in pregnant and fertile non-pregnant women. DESIGN: Prospective cross-sectional study. SUBJECTS: Fifty-one pregnant women at a mean gestational age of 38.9 weeks and 64 fertile non-pregnant women were examined at a University hospital. METHODS: The three layers (adventitia, media, intima) of the superficial wall of the left common carotid artery were identified and measured with high-resolution ultrasound (22.5 MHz). RESULTS: Pregnant women had a thinner intima layer (0.25 +/- 0.07/0.29 +/- 0.08 mm) and a thicker media layer (0.31 +/- 0.08/0.27 +/- 0.09 mm) compared with controls. A statistically significantly higher intima/media ratio was calculated for the pregnant women (1.14 +/- 0.03), compared with the non-pregnant women (0.88 +/- 0.04). CONCLUSION: There are differences in the thickness of the histological layers of the carotid artery wall in pregnant compared with non-pregnant women. This is likely to be due to the effect of different estradiol levels in these two groups.
