Polyarteritis nodosa refers to the condition resulting from inflammation of small and medium-sized arteries. The condition occurs when certain immune cells attack the affected arteries. Polyarteritis nodosa (PAN) is a rare disease that results from blood vessel inflammation ("vasculitis") causing injury to organ systems. Damage occurs as a result. Although the cause of polyarteritis nodosa is unknown, some research has linked it to the presence of microscopic clumps of antibodies from the body's defense system, coupled with foreign proteins, such as portions of a virus.

Polyarteritis nodosa (shortened to PAN) is a rare form of vasculitis in which the medium and/or smaller sized arteries become damaged and inflamed. This activity reviews the causes, pathophysiology, and presentation of polyarteritis nodosa and highlights the role of the interprofessional team in its management. We describe how investigations led . Polyarteritis nodosa can affect renal arteries and damage the kidneys.
The definitive cause of polyarteritis nodosa is not known. PAN may also affect the kidney's blood vessels, resulting in high blood pressure and kidney function damage. Therefore, the symptoms and signs depend on which vessels are affected and to what degree. These vessel changes are reflected on arteriogram as multiple aneurysms and constrictions.
Eventually, the tissues of the vessel die. Polyarteritis nodosa is a serious blood vessel disease in which small and medium-sized arteries become swollen and damaged. Background: PAN is characterized by panmural inflammation of arterioles causing arteriolar ectasia, aneurysm formation, and thrombosis, resulting in organ ischemia.
