Overview
Takayasu arteritis may be classified according to angiographic findings into 6 types which is useful in planning for surgery. 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%). Takayasu arteritis may be classified according to clinical finding into 4 groups of group I, IIA, IIB, and III.
Classification
Takayasu arteritis may be classified according to angiographic findings into 6 types:[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 groups:[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 |
