Prevalence of asymptomatic lower limb venous thrombosis in infertile women with thrombophilic disorders.

Objective: We sought to assess the prevalence of asymptomatic venous thrombosis in infertile women with thrombophilic disorders (TDs).

Methods And Results: A total of 73 infertile women with TDs underwent duplex ultrasound scan to evaluate superficial and deep venous circulation of lower limbs. A control group of 35 infertile women without TDs was included. A single TD was found in 13 (17.8%) subjects, and 40 (54.8%) women presented a combined defect (more than three alterations). No residual mural thrombosis (RT) was noted in any deep veins. We found RT in 48 (65.8%) patients of TD group, while no RT was found in the control group (p < 0.0001). None of the clinical and prothrombotic factors were predictors of RT (all p > 0.20), and frequency of TD did not correlate with multi-vessel RT (p = 0.252).

Conclusions: No signs of deep vein thrombosis but high prevalence of superficial RT is present in infertile women with TDs. Further studies are needed to assess the prognostic value of our findings.
