Femoral vein dialysis is a technique applied in many clinics. Hemorrhagic complications following the procedure either directly due to the femoral catheterization itself in the early period or less with concomitant late neurological impairments may pose serious challenges to the clinician. Likewise in this report, we are presenting a dialysis patient with bilateral retroperitoneal hematomas causing bilateral lumbosacral plexopathies-to our best knowledge the first in the literature. We have also touched upon its prompt diagnosis and treatment. (C) 2003 Elsevier SAS. All rights reserved.
