[Disabling calf pain in the context of venous angiodysplasia: Contribution of dynamic exploration]

We report the case of a 25-year old woman presenting with disabling pain of the left calf, associated with lower left limb angiodysplasia. Dynamic testing (duplex scan and phlebography) showed a popliteal vein ectasia, with reflux into an incompetent lesser saphenous vein: the venous drainage of this ectasia was an embryonic femoropopliteal vein going to the profunda femoris vein. As long as patency and competence of deep veins and of the superficial femoral vein were confirmed by dynamic testing with compressions, curative surgery was considered: en-bloc resection of lesser saphenous vein and of embryonic femoropopliteal vein combined with lateral suture of the popliteal vein. One-year follow-up confirms the absence of recurrent symptoms. Dynamic testing allows safe surgical therapy of persisting embryonic abnormalities associated with incompetent veins, in cases where such testing clearly demonstrates that a sufficient venous drainage of the affected limb will be provided after surgery.
