Many causes of saphenous nerve lesions at the knee or leg level have been reported. Proximal nerve lesions, especially after varicose vein stripping, are uncommon. We report a case of saphenous nerve lesion following catheterization of the femoral artery complicated with arterial spasm. The patient experienced pain for 10 years and only transdermal electroneural stimulation provided sedation. To our knowledge, this is the first published case of such an unusual complication after coronarography, despite the frequency of this procedure. We suggest nerve ischemia could explain the definitive neuralgia.
