My doctor is prescribing me saphenectomy for a saphena of 1.2 cm. I've many varices. Is this the best and safest thing I can do to treat my condition?

Close leaking valves. Varicose veins are a result of malfunctioning valves usually in the saphenous system. The first step in treatment would be to obtain a venous reflux ultrasound to make the diagnosis and help plan treatment which could be laser or radiofreqency closure of the valves usually with microphlebectomies and possible sclerotherapy or ultrasound directed sclerotherapy. You should see a vein specialist.
