Transanal Hemorrhoidal Dearterialization (THD) is a minimally invasive procedure designed to treat hemorrhoids by ligating the arteries supplying them. This technique effectively reduces symptoms while preserving the surrounding tissue and minimizing discomfort.

THD is performed using an anoscope equipped with a Doppler ultrasound probe to locate the hemorrhoidal arteries. These arteries are then tied off with sutures, cutting off the blood supply to the hemorrhoids. This results in their gradual shrinkage.

The procedure is typically performed under local or regional anesthesia and has a quick recovery time. Patients experience minimal pain and can resume normal activities within a few days. Proper post-treatment care, including a high-fiber diet, supports recovery.

Patients benefit from THD as it offers a safe and effective alternative to more invasive hemorrhoid surgeries. This approach ensures significant symptom relief with minimal impact on daily life.
