Abstract

247 The disease is named after the Japanese ophthalmologist Mikito Takayasu, who described the first case in 19081. The highest incidence is found in Japan of 30 cases per million per year2. It is mainly a disease of young females; however, male to female ratio varies around the world2. The disease has a predilection for the aorta, aortic branches, pulmonary and coronary arteries. Patients from Japan and South America are more likely to have thoracic aorta involvement while involvement of the abdominal aorta is more common in other Asian and Middle Eastern patients3.
