Bleeding of aneurysm of cervical arteries is an emergency situation in ENT surgery. Compression of trachea and big cervical veins together with blood loss needs immediate treatment. Three cases are demonstrated presenting diagnostic and therapeutic management of one spontaneous respectively posttraumatic aneurysm of the inferior thyroid artery, and two aneurysms of lingual respectively facial artery after tonsillectomy. Interventional angiography plays an important role in overcoming such problems. Intravasal application of a platinum coil stops bleeding of the aneurysm and surgical revision of the neck can be avoided.
