Blood Vessels Pathology Flashcards
[syndrome]
gain of function of ENaC channel resulting to increased Na reabsorption and then hypertension
Liddle Syndrome
Associated condition
eosinophilic hyaline material with associated luminal narrowing
essential hpn
DM
[associated condition]
concentric, laminated thickening, onion skin lesion, note of fibrinoid deposition and vessel wall necrosis
malignant hypertension
location of neovascularization in an atheromatous plaque
periphery
[clinical phase of atherosclerosis]
mural thrombosis, embolization, and wall thickening can lead to
aneurysm and rupture
[clinical phase of atherosclerosis]
plaque rupture, plaque erosion, plaque hemorrhage, mural thrombosis, embolization can lead to
occlusion by thrombus
[clinical phase of atherosclerosis]
progressive plaque growth can lead to
critical stenosis
usually 70%
the larger the lipid core, the ____stability of the plaque
greater the stability of the plaque
Remember, size of lipid core is inversely proportional to stability
the lesser the degree of inflammation, the ____ stability of the plaque
greater stability
remember, degree of inflammation is inversely proportional to stability
the thicker the fibrous cap, the ___ stable the plaque
more stable the plaque
fibrous cap is directly proportional to stability
[dissection]
intima tear involvinf the descending aorta only.
What is the standford classification?
Stanford B
DeBakey III = Standford B
[aortic dissection]
Both ascending and descending aorta are involved.
What is it s debakey classification?
DeBakey I
[diagnosis?]
45/M, hypertensive with marfan syndrome.
Noted sudden, excruciating anterior chest pain, radiating to the back and downward
aortic dissection
[syndrome]
Non-infectious small artery vasculitides, p-anca positive
churg-strauss syndrome
[syndrome]
non-infectious small artery vasculitides, c-anca positive
Wegener granulomatosis/ granulomatosis with polyangitis
[diagnosis]
headache among elderly individual, along course of superficial temporal artery, associated with multiple joint pains
giant cell arteritis
[diagnosis]
affects large vessels of the aortic arch, notable ocular disturbances and weakened UE pulses
takayasu
[diagnosis]
associated with hepatitis B, renal and visceral vessels (NEVER PULMONARY)
clinically, HPN and visceral ischemia
prominent fibrinoid necrosis, segmental, transmural, necrotizing
polyarteritis nodosa
[diagnosis]
fever >5 days, conjunctival injection, mucosal erythema, cervical lymphadenopathy, polyamorphous exanthem
kawasaki disease
important cause of MI in children; can cause coronary artery aneurysm
less prominent fibrinoid necrosis, segmental, transmural, necrotizing
kawasaki disease
[diagnosis]
associated with connective tissue disorders
common in kidney and LUNG; hemoptysis, hematuria
microscopic polyangitis
PAN = no lung involvement
[diagnosis]
associated with asthma, allergic rhinitis, eosinophilia
noted involvement of cutaneous, GIT, renal and cardiac vessel
Clinically, palpable purpura, GI bleed and FSGS
churg-strauss syndrome
[diagnosis]
PAN + extravascular necrotizing granulomas and hypereosinophilia
Churg-strauss syndrome
Remember, atopy/eosinophilia = sneeze = aaachooo = aaaachurg
[diagnosis]
fragmented PMNs in post capillary venule (leukocytolasia)
Microscopic polyangitis
