Fourteen-year data say it depends enormously on which procedure — twelvefold. Then the same data say quality of life ended up identical, which changes what the recurrence rate is telling you. ## Answer Often, and how often depends on the procedure. In a randomised trial followed for fourteen years, recurrent above-knee reflux occurred in 2.6 percent after high ligation and stripping, 6.1 percent after endovenous laser ablation and 30.8 percent after ultrasound-guided foam sclerotherapy, with re-intervention on the vein required in 13.2, 8.2 and 56.4 percent respectively — yet Aberdeen Varicose Vein Questionnaire scores at fourteen years were comparable across all three groups (overall P = .21). ## Key takeaways - 233 patients with symptomatic great saphenous vein reflux were randomised to stripping, laser ablation or foam sclerotherapy; 214 were analysed at fourteen years. - Recurrent above-knee reflux: 2.6 percent after stripping (1 of 38), 6.1 percent after laser (3 of 49), 30.8 percent after foam sclerotherapy (12 of 39). - Re-intervention on the great saphenous vein: 13.2 percent after stripping, 8.2 percent after laser, 56.4 percent after foam sclerotherapy. - Foam sclerotherapy carried a risk ratio for recurrent reflux of 11.7 against stripping and 5.0 against laser ablation. - Stripping and laser ablation performed comparably to each other on both measures. - Neovascularisation — new small vessels at the treated site — did not differ between treatments (29.0, 22.5 and 23.1 percent, P = .76). - Quality of life at fourteen years did not differ between the three groups (overall P = .21). ## Full article Most figures quoted for varicose vein recurrence come from follow-up at one, two or five years. Veins recur over decades, so those numbers describe the beginning of the answer. A Finnish randomised trial went back to its patients after fourteen years, and the result splits into two halves that point in opposite directions. ### The recurrence rates differ enormously **Fourteen-year outcomes by treatment** | | Stripping | Laser ablation | Foam sclerotherapy | | --- | --- | --- | --- | | Recurrent above-knee reflux | 2.6% | 6.1% | 30.8% | | Re-intervention on the vein | 13.2% | 8.2% | 56.4% | | Neovascularisation | 29.0% | 22.5% | 23.1% | So the honest answer to whether veins come back is that it depends far more on which procedure was done than on anything about the patient. Foam sclerotherapy sent more than half of its patients back for another procedure inside fourteen years. Laser ablation sent fewer than one in twelve. ### And then the quality of life was the same > **What a recurrence rate is actually counting** > At fourteen years all three groups reported comparable symptom scores. That is not a contradiction of the recurrence figures — it is what happens when a recurrence gets treated. Once the second procedure is done, the recurrence stops being a symptom and becomes a past appointment. So the re-intervention rate measures how many times you are likely to be back in a clinic, not how your leg is likely to feel in fourteen years' time. Those are both real costs and they are not the same cost. Which one matters more is a question about the patient, not about the vein. Somebody who would find a second and third procedure an ordinary inconvenience is choosing differently from somebody for whom another operation is a serious undertaking, and the trial cannot decide that for either of them. ### What to ask before the procedure The useful question is not "will it come back" but "what is the fourteen-year re-intervention rate for the specific procedure you are proposing". Stripping and laser ablation came out comparable to each other on both recurrence and re-intervention; foam sclerotherapy did not, and it is the technique most often described to patients as the least invasive option. One further note on the numbers: the groups in this trial contained 38 to 49 patients each at fourteen years, so a single additional recurrence moves a percentage noticeably. The twelvefold gap is large enough to survive that; the difference between 2.6 and 6.1 percent is not. ## Sources - Rahman T, Noronen K, Vähäaho S, Halmesmäki K, Venermo M.
