Answer

Takayasu arteritis can be divided into the following six types based on angiographic involvement (see Workup) [3] :

  • Type I - Branches of the aortic arch
  • Type IIa - Ascending aorta, aortic arch, and its branches
  • Type IIb - Type IIa region plus thoracic descending aorta
  • Type III - Thoracic descending aorta, abdominal aorta, renal arteries, or a combination
  • Type IV - Abdominal aorta, renal arteries, or both
  • Type V - Entire aorta and its branches
