title: [Acute groin pain and femoral nerve deficit in a warfarin treated patient].
abstract: Warfarin is frequently used as an anticoagulant. The most common and serious complication is bleeding. We present a 43-year-old warfarinized patient who was admitted with unilateral groin pain and a neurological deficit of the lumbar nerve root L1-4. A CT scan showed a haematoma in and behind the ilio-psoas muscle extending to below the inguinal ligament, due to a warfarin induced coagulation deficit (INR 7.0) which was reversed on admission with vitamin K. There is no conclusive evidence in the literature supporting either conservative or surgical treatment modalities. Our patient was successfully treated conservatively.
