What are two Large vessel vasculitides?
Temporal (Giant Cell) Arteritis
Takayasu Arteritis
What type of vasculitis is Temporal Arteritis? What vessel does it usually affect?
Granulomatous vasculitis that classically involves branches of the carotid artery.
What demographic does Temporal Arteritis affect?
Older adults (>50) usually women
What are the presenting symptoms of temporal arteritis?
Headache (temporal artery involvment), visual disturbances (opthalmic artery involvment), jaw claudication. FLu like symptoms with joint and muscle pain (polymyalgia rheumatica).
What is an irregular lab value seen in temporal arteritis?
ESR is elevated
What does a biopsy reveal in temporal arteritis? What is important to keep in mind when taking a biopsy segment?
Biopsy reveals inflamed vessel wall with giant cells and intimal fibrosis. Must take long segment because lesions are segmental.
What is the treatment of temporal arteritis. What major complication indicates early treatment even without confirmative diagnosis?
Treatment is corticosteroids. there is a high risk of blindness without treatment.
What type of vasculitide is takayasu Arteritis?
Large vessel granulomatous vasculitis very similar to temporal vasculitis.
What vessels does takayasu arteritis affect?
involves aortic arch at branch points.
What demographic does takayasu arteritis affect?
adults (<50) classically young asian females
What are the presenting symptoms of Takayasu arteritis?
visual and neurological symptoms with a weak or absent pulse in the upper extremity (pulseless disease)
What lab value is elevated in takayasu arteritis?
ESR
What is the treatment of takayasu arteritis?
Corticosteroids
Name 3 medium vessel vasculitides?
Polyarteritis nodosa
Kawasaki disease
Buerger Disease
What type of vasculitis is PAN? What type of arteries does it affect? which organs?
Medium vessel (muscular arteries supplying organs) necrotizing vasculitis. All organs except lungs.
How does PAN present?
In young adults as hypertension (renal artery involvment), abdominal pain with melena (mesenteric artery), neurological disturbances, and skin lesions.
What virus is PAN associated with?

What is a major feared complication of kawasakis disease (which artery)
Coronary artery involvment is common and leads to risk for thrombosis with MI and aneurysm with rupture
How is kawasaki disease treated?
Aspirin and IVIG, disease is self limiting
What doe early lesions of PAN show?
transmural inflammation with fibrinoid necrosis
What type of vasculitis is buerger disease? what body parts does it affect?
medium vessel vasculitis involving digits.
How does beurger disease present?
ulceration, gangrene, and autoamputation of fingers and toes, raynaud phenomenon is often present.
