Overview

Takayasu arteritis may be classified according to angiographic findings into 6 subtypes. The most common type is type III, which is found in as many as 65% of patients. The most commonly involved vessels include the left subclavian artery (50%), left common carotid artery (20%), brachiocephalic trunk, renal arteries, celiac trunk, superior mesenteric artery, and pulmonary arteries (50%). Infrequently, the axillary, brachial, vertebral, coronary, and iliac arteries are involved.

Classification

Takayasu arteritis may be classified according to angiographic findings into 6 subtypes:

Type I:Branches from the aortic arch

Type IIa:Ascending aorta, aortic arch and its branches

Type IIb:Ascending aorta, aortic arch and its branches, thoracic descending aorta

Type III:Thoracic descending aorta, abdominal aorta, and/or renal arteries

Type IV:Abdominal aorta and/or renal arteries

Type V:Combined features of types IIb and IV
