Randy Shafritz, MD


I specialize in minimally invasive treatment for both venous and arterial diseases. I have extensive training and experience in minimally invasive treatment for varicose veins, venous insufficiency, and the treatment of leg ulcers. I was the first physician in Monmouth County to introduce the venous closure procedure into daily practice, and have been doing it for three years now. I also perform the trivex procedure for varicose vein removal. Sclerotherapy for spider veins is also available. Procedures for treatment of arterial disease include angioplasty, stenting, cryoplasty, and atherectomy, all performed minimally invasively, as well as surgical bypass.
