peripheral vascular disease Flashcards
common infectious causes of aneurysm
Mycotic aneurysm (mucormycosis)
Syphillis (Treponema pallidum)
treatment giant cell / temporal arteritis
high dose steroids
histology Microscopic polyangiitis (leukocytoclastic vasculitis)
fibrinoid necrosis,
neutrophils
nuclear dust (Karyorrhexis)
clinical features of thoracic aortic aneurysm
mediastinum encroachment: tracheal/esophogeal compression,
bone erosion,
cough (larygneal nerve)
Heart failure due to insuficient aortic valve, aortic rupture
Pressentation, pathogensis, vessels
Takayasu Arteritis
Pulseless disease (UE)
ocular disturbances
Japanese women
granulomatous inflammation of aortic arch+ branches
pulmonary, coronary, renal artery pos.
autoimmune etiology
presentation, pathogenesis, vessels Churg Strauss
palpable purpura, GI bleeding, Renal impairment, Cardiomyapthy, MPO ANCA +
possible hyper-response to allergic stim
Small Vessel vasculitis associated with - asthma, allergic rhinitis, peripheral eosinophilia, necrotizing granulomas
presentation aotic dissection
stabbing or tearing anterior chest pain radiating to back
most common location of aortic dissection
ascending aorta
aortic disection = ____ tear within 10 cm of ___
intimal tear within 10 cm of aortic valve
(dissection palce between middle and outer thirds of wall in media0
ehlers dalos vs marfans
ehlers danlos - type iII collagen
marfans- fibrillin
presentation, pathogenesis, vessels
Microscopic Polyangiitis (Leukocytoclastic Vasculitis)
Clinical depends on vascular bed (hemoptysis, hematuria, protinuria, abd pain and muscle pain or bleeding, cutaneous purpura)
Arterioles, cappillaries, venules of Skin, mucous membranes, **lungs, kidneys **brain, heart, GIT, muscles
Thromboangiitis Obliterans (Buerger)
smokers,
Painful ischemia, gangrene of limbs
inflammation and thrombosis of medium-small muscular arteries and secondarily, nerves and veins. Tibial and radial artery esp.
Raynaud phenom
prosymall pallor or cyanosis of fingers, toes, nose, easrs
healthy young woman
recurrent vasospasm, no strucutral changes in arterial wall until late.
(can be secondary to arterial insufficiency due to SLE, SS, atheroscloriss, beurger)
presentation, pathogenesis, vessels
wegner granulomatosis
PR3-ANCA positive
40yo Pneumonitis, Sinusitis, Nasopharyngeal ulcerations, Renal Dease
necrotizing vasculitis > granulomas of lung or UR+ENT (likely cell mediated hypersensitivitiy)
vasculitis of small-medium in lung and UR tract
Glomerulonephritis
histology Kawaski’s
necrosis and inflammation
savular vs fusiform anyeurism
sacular buldges out one side, unilateral
fusiform: uniform expansion of the vessel
