Overview
Takayasu arteritis may be classified according to angiographic findings into 6 subtypes. These systems are useful in that they allow a comparison of patient characteristics according to the vessels involved and are helpful in planning surgery, but they offer little by way of prognosis. 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:[1]
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
