Treatment of Varicose Veins
Radiofrequency ablation is a minimally invasive procedure used in the treatment of varicose veins. It is an alternative to the traditional stripping operation. Under ultrasound guidance, a radiofrequency catheter is inserted into the abnormal vein and the vessel treated with radio-energy, resulting in closure of the involved vein. Radiofrequency ablation is used to treat the great saphenous vein, the small saphenous vein, and the perforator veins. The latter are connecting veins that transport blood from the superficial veins to the deep veins. Branch varicose veins are then usually treated with other minimally invasive procedures, such as ambulatory phlebectomy, sclerotherapy, or foam sclerotherapy. Currently, the VNUS ClosureRFS stylet is the only device specifically cleared by FDA for endovenous ablation of perforator veins.
It should be pointed out that the possibility of skin burn during the procedure is very small, because the large volumes (500 cc) of dilute Lidocaine (0.1%) tumescent anesthesia injected along the entire vein prior to the application of radiofrequency provide a heat sink that absorbs the heat created by the device. Early studies have shown a high success rate with low rates of complications.

“The treatment of the incident of the assault upon the sailors of the Baltimore is so conciliatory and friendly that I am of the opinion that there is a good prospect that the differences growing out of that serious affair can now be adjusted upon terms satisfactory to this Government by the usual methods and without special powers from Congress.”

“To me, nothing can be more important than giving children books, It’s better to be giving books to children than drug treatment to them when they’re 15 years old. Did it ever occur to anyone that if you put nice libraries in public schools you wouldn’t have to put them in prisons?”
—Fran Lebowitz (20th century)
“Time for the flat-headed man. I recognize that listener,
Him with the platitudes and rubber doughnuts,
Melting at the knees, a varicose horror.
Hello, hello. My nerves knew you, dear boy.
Have you come to unhinge my shadow?”
—Theodore Roethke (1908–1963)
“When first the college rolls receive his name,
The young enthusiast quilts his ease for fame;
Through all his veins the fever of renown
Burns from the strong contagion of the gown;”
—Samuel Johnson (1709–1784)
