In Takayasu arteritis, which artery is involved in about half of patients?

Explanation:
Takayasu arteritis is a large-vessel vasculitis that targets the aorta and its major branches. The disease can affect several high-flow vessels, and involvement of the pulmonary arteries is seen in about half of patients. This pulmonary involvement can contribute to dyspnea and may lead to pulmonary hypertension. While carotid and renal arteries can also be affected, their involvement is not as consistently seen at that frequency as the pulmonary arteries. So, the pulmonary arteries are the most common non-aortic vessel involved, explaining why they are the correct choice.
