Polyarteritis nodosa PANalso known as panarteritis nodosa[1] periarteritis nodosa[1] Kussmaul diseaseor Poliatreritis disease, [2] is a systemic necrotizing inflammation of blood vessels vasculitis affecting medium-sized muscular arteries, typically involving the arteries of the kidneys and other internal organs but generally sparing the lungs’ circulation.

Traditionally, it has been taught that relapses of polyarteritis nodosa PAN are rare in individuals who completely recover.

Characteristically, the biological signs of inflammation is absent in FMD except in cases of associated infarction. Notably, the incidence of RA-associated vasculitis has decreased greatly since the s, likely attributable to improvements in the management of RA.

PAN apparently has two effects on the eye; typical thickening of the wall and diminution of the lumina of the arteries of the various ocular coats and as retinal edema, transudates, hemorrhages and cytoid body formation; these changes are probably effected through renal alteration leading to HT.

It is also important to realize the limitations poliarterifis angiography in the diagnosis of both vasculitis and FMD. PAN may develop in a subacute fashion, over several weeks or months. After 5 days of intensive care follow up the patient had normal blood pressure.
