Hemorrhoids are often caused by increased arterial blood flow, leading to swelling, bleeding, and severe discomfort. The THD (Transanal Hemorrhoidal Dearterialization) Doppler procedure is a state-of-the-art, minimally invasive surgical technique designed to locate and treat this root cause directly, without the need for painful surgical cutting or excision of tissue.
During the procedure, the surgeon uses a specially designed proctoscope equipped with a microscopic Doppler ultrasound probe. This advanced technology allows the doctor to precisely listen for and locate the specific terminal arteries feeding the hemorrhoids. Once identified, these arteries are carefully tied off (ligated) with a suture, instantly cutting off the excess blood supply so the hemorrhoids shrink and resolve naturally.
