Femoral Neuropathy in Renal Transplantation

Abstract

ABSTRACT:Acute femoral neuropathy after renal transplantation is an uncommon and rarely recognized complication. Recovery of the nerve is usual. Although rare, five cases have come to our attention in the past twenty years. A detailed clinical and electrophysiological analysis with a six month follow-up is presented. A review of sixteen other reported cases is also provided. The possible pathophysiology including direct compression and nerve ischemia, is discussed. We believe that nerve ischemia, possibly caused by a steal phenomenon, occurs in all cases following the anastomosis of the graft renal artery to the internal iliac artery, with a superimposed component of compression in some cases. The severity of ischemia probably determines the degree of recovery.
