RESUMEN
BACKGROUND: Routine preoperative duplex examination led to an improvement in results 2 years after surgery for primary varicose veins. The aim of the present study was to evaluate the impact of preoperative duplex imaging after 7 years, in relation to other risk factors for varicose vein recurrence. METHODS: Patients with primary varicose veins were randomized to operation with (group 1), or without (group 2) preoperative duplex imaging. The same patients were invited to attend follow-up with interview, clinical examination and duplex imaging. Quality of life (QoL) was measured with the Short Form 36 questionnaire. RESULTS: Some 293 patients (343 legs) were included initially; after 7 years 227 were interviewed, or their records reviewed: 114 in group 1 and 113 in group 2. One hundred and ninety-four legs (95 in group 1 and 99 in group 2) were examined clinically and with duplex imaging. Incompetence was seen at the saphenofemoral junction and/or saphenopopliteal junction in 14 per cent of legs in group 1 and 46 per cent in group 2 (P < 0.001). QoL was similar in both groups. After a mean follow-up of 7 years (and including patients who underwent surgery after the review), 15 legs in group 1 needed reoperation and 38 in group 2 (P = 0.001). CONCLUSION: Routine preoperative duplex imaging improved the results of surgery for primary varicose veins for at least 7 years.

OBJECTIVES: To investigate the recurrence rate after sapheno-femoral junction (SFJ) ligation and great saphenous vein (GSV) stripping for varicose veins (VV), to evaluate risk factors for recurrence and to classify the anatomy of the recurrence in the groin. Design. Clinical follow-up study. METHODS: Eighty-nine consecutive patients with 100 operated legs were re-examined clinically and with duplex after 6-10 years. Fourteen groins were re-explored, 13 after varicography. The anatomy in the groin was classified according to the Edinburgh system. The original medical records were examined to check for risk factors which could lead to a recurrence. RESULTS: Fifty-seven legs had incompetent veins in the groin according to duplex. In 54 of them, it was possible to define whether the incompetent veins emanated from the former SFJ. Varicography and operative findings correlated well to duplex. The main difficulty was to distinguish neovascularization from residual branches. No significant risk factor for recurrence was found in the medical records. CONCLUSIONS: Recurrence of VV after SFJ ligation is common irrespective of perioperative difficulties or the surgeon's experience. The anatomy of recurrence in the groin is difficult to classify according to the Edinburgh system mainly because neovascularization is difficult to verify.
