Persistent sciatic vessels, varicose veins, and lower limb hypertrophy: an unusual case or discrete clinical...

Persistent sciatic artery is a rare congenital anomaly with a high incidence rate of aneurysmal degeneration and risk of thromboembolization or rupture. Despite a number of recognized associations, the presence of coexistent venous anomalies is extremely rare. We present the case of a 27-year-old woman with atypical left-sided varicose veins and soft tissue hypertrophy. Imaging showed persistence of both sciatic artery and vein. Whether these anomalies are an incidental finding or represent a discrete clinical syndrome remains unclear. We emphasize that unusual distribution varicose veins may be associated with underlying persistent sciatic vessels and recommend formal duplex scan assessment for these anomalies.
