Persistent Sciatic Veins

Persistence of the sciatic vein is a venous anomaly located in the lower limbs. Accounts in the literature rarely include patients who do not have the Klippel-Trenaunay-Weber syndrome. We present a case of a woman with bilateral persistent sciatic veins and no Klippel-Trenaunay-Weber syndrome, first suspected on a duplex ultrasound examination and then confirmed by computed tomography angiography. Persistent sciatic vein is a rare venous anomaly. Although the prevalence of persistent sciatic veins is possibly underestimated, we should be aware of its presence, considering its relevance in contributing to venous disease.
