Endovenous Obliteration of Primary Varicose Vein of Greater Saphenous Vein by Radiofrequency Heating: A Preliminary Report / 대한피부과학회지

ABSTRACT

BACKGROUND: For the treatment of primary varicose vein of greater saphenous vein(GSV) due to reflux from incompetent saphenofemoral junction(SFJ), several methods such as ligation and stripping, or duplex-guided sclerotherapy have traditionally been introduced. As for sclerotherapy, the recurrence rate has been reported to be very high. In spite of higher success rate, traditional high ligation with stripping of GSV requires several days' admission with general anesthesia and several more days before returning to normal daily life. New modalities, which are less invasive and possibly have lower recurrence to rate with a chance for early ambulation, are being proposed. They are such as endovenous radiofrequency(RF) therapy, endovenous laser therapy, etc. OBJECTIVE: We tried to evaluate the efficacy and safety of endovenous RF therapy as an alternative to high ligation and stripping in case of GSV varicosity in mild to moderate degrees. METHODS: Both GSV varicosities and varicosed tributaries are marked by doppler and/or ultrasonic imaging. A catheter connected to RF generator is inserted proximally through the incision of vein wall percutaneously, usually above or below the knee. After confirming position of the SFJ using ultrasound, the catheter is progressed as far as to 1-2cm below the SFJ. Then, the generator is activated and the catheter withdrawn slowly for complete heating and occlusion of the target vein. Additional ambulatory phlebectomy or sclerotherapy is optional. We wrap the limbs with self-adhesive short stretch bandage for 2-3 days and encourage the patient to walk regularly and wear compressive stocking later. RESULTS: We performed endoluminal RF treatment on 10 legs of 9 patients(5 males and 4 females). Follow-up intervals varied from 2 to 10 months. Patients were generally satisfied with improvement of symptom. On the clinical evaluation with doppler and duplex examination, there were a few blood flows except only some segments of GSV in 7 patients CONCLUSION: Although endoluminal RF therapy may have a somewhat higher recurrence rate than that of traditional high ligation with stripping of GSV, endoluminal RF therapy is expected to have several advantages over traditional surgery, including less invasiveness, no need for admission or general / spinal anesthesia, earlier return to normal daily life, and finally easy performance, especially for the dermatologist.
