I can't do laser radio ablation for a saphena of 1.2 CM becasue it is too big. I've done angiotc no malformation. Is the only resort I have saphenectomy?

No. . I do ablutions of that size all the time. Laser works better than rf here because you can tailor energy dosing. See another doctor and get another opinion. Miamibeachvein.Com.
