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 | Vessel involvement |
|---|---|
| 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 |
Takayasu arteritis may be classified according to clinical finding into 4 subtypes:[2]
| Group | Clinical features |
|---|---|
| Group I | Uncomplicated disease, with or without pulmonary artery involvement |
| Group IIA | Mild/moderate single complication together with uncomplicated disease |
| Group IIB | Severe single complication together with uncomplicated disease |
| Group III | Two or more complications together with uncomplicated disease |
