Painless bright red peranal bleeding is a leading symptom of first and second degree hemorrhoid. After having excluded the possibility of bleeding in an upper region diagnosis is made proctoscopically, which is generally followed by injection therapy. Arterial blood supply can be reliably imaged with the aid of 20 MHz microvascular Doppler sonography and the success of therapy can be verified as well as documented after injecting a sclerosing substance.
