Patient's question:
Hello, what is giant cell arteritis?Doctor's answer:
Polyarteritis nodosa refers to a chronic, non-specific inflammatory disease affecting the aorta and its major branches and the pulmonary artery. This inflammation is not the kind commonly seen by the general public, such as infectious inflammation, but rather a sterile inflammation caused by a disorder in the body's immune system. Its clinical manifestations are primarily related to the affected blood vessels. For this condition, it is first recommended to visit the autoimmune rheumatology department of a tertiary general hospital for a follow-up examination. This disease is relatively rare, and treatment can be challenging.
