Abstract

We report one case of unilateral femoral neuropathy secondary to iliacus and psoas hematoma in a patient with anticoagulant therapy after surgery of cardiac valves replacement. Femoral neuropathy was confirmed by electrodiagnostic studies. Diffuse swelling of left iliacus and iliopsoas muscles with acute to subacute hematoma formation appeared in computed tomography of pelvis. A motor nerve conduction study showed absent compound muscle action potentials in left femoral nerve. The needle electromyographic examination showed positive sharp waves and fibrillation potentials in the left rectus femoris, vastus medialis, and vastus lateralis muscles. For minimizing the complication of anticoagulant therapy, we suggest that clinicians need to carefully monitor and optimize the prothrombin time.
