Takayasu's arteritis is a chronic vasculitis which is more common in women, usually aged 20-40 years old.
This condition results in narrowing of the first few centimetres of the carotid, inominate, and subclavian arteries with the aorta. Also the condition affects the renal arteries.
The clinical features result from ischaemia due to arterial stenoses and thrombosis.
The aetiology is unknown.
