    Abstract:
    OBJECTIVES: The aim of this study was to identify the incidence and distribution of nerve damage in patients undergoing primary venous surgery. METHODS: Patients undergoing primary great saphenous vein surgery between February and November 2003 were enrolled. In all cases the great saphenous vein was 'flush' ligated at the sapheno-femoral junction and stripped to the knee by inversion without using a stripper head; multiple phlebectomies were performed using an Oesch hook. A vascular nurse followed up patients 6 weeks post-operatively. Those reporting altered sensation and/or pain were examined by a doctor to provide an objective assessment of any neurological damage. These patients were again followed up by telephone at 6 and 12 months. RESULTS: Sixty-three limbs from 54 patients were enrolled. Numbness or paraesthesia was identified in 17 (27%) limbs at 6 week follow-up. 11 (17%) limbs were affected below the knee and 7 (11%) limbs were affected at the thigh or groin. One of the limbs was affected above and below the knee. Of these 17 limbs there was resolution in six limbs at 6 months and nine limbs at 12 months. Two patients with persistent nerve lesions regretted undergoing surgery. Patients undergoing bilateral surgery were more likely to report abnormal sensation (chi(2) test, p=0.006). There was no significant difference between the incidence of nerve injury for consultant, SpR or SHO as first operator (chi(2) test, p=0.9). CONCLUSION: This study demonstrates the frequency of nerve injury during primary great saphenous vein surgery. It will be useful for clinicians providing informed consent and may provide a benchmark for comparison with newer techniques.
