Factors Associated with Varicose Veins in Pregnant Women

Abstract

Objective:

To examine the associated features in pregnant women with superficial venous reflux, compared with those without reflux.

Methods:

Pregnant women were recruited at booking and underwent colour flow duplex ultrasound scanning of the lower limbs to ascertain the presence or absence of reflux in the superficial veins. Body mass index and CEAP scores were calculated. A questionnaire regarding parity, smoking habit and family history of varicose veins was administered. Statistical analysis was carried out using ARCUS.

Results:

Three hundred and twenty-nine women were recruited, of whom 83 were identified as having reflux (25%). No relationship was observed between reflux and obesity, smoking or family history. Multiparity was significantly correlated with varicose veins (p<0.03). CEAP scores were higher in multiparous women with varicose veins. An increase in symptoms was associated with a positive family history (especially maternal). Smoking was associated with fewer symptoms in those with reflux, as was obesity.

Conclusion:

Increased parity increased the likelihood of varicose veins, but obesity and family history appeared to make no difference. Symptoms were greater in multiparous women, but less inobese women. An association was made between smoking and fewer symptoms.
