ObjectivesThe aim of this study was to identify the incidence and distribution of nerve damage in patients undergoing primary venous surgery.MethodsPatients 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.ResultsSixty-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).ConclusionThis 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.
