Phlebology is a medical speciality that is concerned with venous issues including the diagnosis and treatment of disorders of the veins. A medical specialist in this field is known as a phlebologist. The specialty of phlebology has developed to enable physicians sharing an interest in venous disease and health to share knowledge and experience despite being trained in a variety of backgrounds such as dermatology, vascular surgery, haematology, interventional radiology or general medicine. Diagnostic techniques used include the patient's history and physical examination, venous imaging techniques in particular vascular ultrasound and laboratory evaluation related to venous thromboembolism. The American Medical Association and the American Osteopathic Association have added phlebology to their list of self-designated practice specialties. A significant part of a phlebologist's work is involved with the treatment of superficial venous disease, frequently of the leg. Conditions often treated include venous stasis ulcers, varicose veins and spider veins (telangiectasia). Other conditions managed by phlebologists include deep venous thrombosis (DVT), superficial thrombophlebitis, and venous malformations. The Union Internationale de Phlébologie (UIP) is committed to the global expansion of knowledge in the growing field of phlebology and aims to facilitate the advancement of science by encouraging research and education in all aspects of venous and lymphatic disease. The Union is ultimately aiming to facilitate comprehensive training programs in its member countries with the ultimate aim of establishing phlebology as a recognised multidisciplinary specialty of medicine. The Australasian College of Phlebology (ACP) founded in 1993 has established a comprehensive four year training program in phlebology incorporating an online modular curriculum that complements supervised clinical training. The American Medical Association added phlebology to their list of self-designated practice specialties in 2005.
