Pulmonary Vascular Disease Pathology Flashcards
what will chest X ray look like with PE?
normal
what is a drug that is a risk factor for DVT and PE?
oral contraceptives
name the coagulation genetic disorder that is a risk factor for PE?
factor V leiden
what is the name of the infarct that PE lead to?
wedge infarcts
what goes on in the wedge infarct? 2 things
hemorrhage and necrosis
name the four steps in development of PH in vessels
medial hypertrophy
intimal proliferation
intimal fibrosis
plexiform vascular lesion
describe what a plexiform vascular lesion looks like
totally blocked off vessel that looks like it is trying to recanalize with diffuse pink spots
what antibodies are associated with microscopic polyangitis?
MPO antibodies
what antigen is associated with granulomatis with polyangitis?
PR3 antigen
what appearance will diffuse alveolar hemoptysis disorders have on X ray?
diffuse ground glass opacities
name the three alveolar hemorrhage syndromes to know
goodpasture syndrome
acute lupus pneumonitis
granulomatous poly angitis
how is goodpasture syndrome mediated?
antibodies bind to antigen directly on the surface of the basement membrane of small vessels
what are goodpasture auto antibodies against?
type IV collagen in basement membrane
what two organs mainly suffer from goodpastures?
kidney and lung
how can you see goodpasture auto antibodies?
in serum or in immunofloresence (IF)
will goodpasture have a linear or splotchy appearance in basement membrane?
linear
how is acute lupus pneumonitis mediated?
auto antibodies bind in blood and form complex that deposits in basement membrane of small capillaries
is acute lupus pneumonitis patchy or smooth in appearance in basement membrane?
patchy because deposits will happen wherever they can
how is granulomatour polyangitis mediated?
antibodies bind the neutrophils and activate them…leading to necrotizing granulomatour vasculitis
describe granulomatous polyangitis in three words
necrotizing granulomatous vasculitis
what is the antibody in granulomatour polyangitis?
ANCA
what does granulomatour polyangitis lead to?
nodules that can cavitate
