ABSTRACT
BACKGROUND:
Microvascular remodeling is one major responsible for vascular adaptation in pregnancy, still it is not routinely evaluated in the obstetric field. This pilot study aimed to explore the role of nailfold capillaroscopy (NCV) in detecting microvascular changes during normal pregnancy.METHODS:
A population of 30 healthy pregnant women was longitudinally followed performing clinical assessment and NVC evaluation at each trimester and post-partum. Thirty non-pregnant age-matched healthy women having received at least two NVCs with a minimum 9 to 12-month interval were selected as controls. All NVC images were evaluated by a qualitative and semi-quantitative assessment using current standardised approach. Statistical analyses were conducted to assess NVC trend throughout gestation and its possible association with pregnancy course.RESULTS:
A progressive significant increase of NVC neoangiogenesis and a specular reduction in capillary dilations was observed during pregnancy (p < 0.05). These variations were not found in age-matched controls, who showed stable NVC parameters over a similar time frame (p < 0.05). Additionally, a significant inverse correlation was found between NVC neoangiogenesis rate and maternal systemic BP (rho = -0.72, p < 0.005).CONCLUSION:
This first comprehensive longitudinal NVC evaluation during normal pregnancy reports significant but physiological microvascular variations throughout gestation, suggesting NVC as a safe and promising technique for further investigate and define patterns of microvascular changes also in pathological pregnancies.Key words
