title: Painful sciatic neuropathy following cardiac surgery.
abstract: Ten patients developed bilateral asymmetrical lower limb sensori-motor or motor deficits associated with prominent causalgic pain after cardiac surgery. The clinical and electrophysiological abnormalities indicated bilateral proximal sciatic nerve lesions, although in several cases the distinction from a diffuse ischaemic axonopathy was difficult to make. This pattern of postcardiac surgery peripheral neurological dysfunction has not been previously described but is likely to relate either to the intra-operative posturing technique for access to the saphenous veins and/or the upright posture used to nurse patients in the immediate post-operative period and is in keeping with the previously demonstrated susceptibility of peripheral nerves to pressure palsy during cardiac surgical procedures.
