Q

giant cell arteritis is a large vessel vasculitis charechterised by …

A

​chronic granulomatous reaction → granulomas in lumens of SEGMENTS of arteries in the Head such as temporal ,vertebral , ophthalmic →ischemia

-t-cell mediated response against vessel wall antigen

affects old ages - *take large biopsy*

Q

Takayasu large vessel vasculitis is charactarised by…

A

“Pulseless disease”-in asian noodle motherfuckers

  • intimal hyperplasia and thickening of vessel wall
  • collagenous scarring → reduced BP ,weaker pulse in upper extremities

Q

Microscopic Polyangiitis aka “leukocytoclastic vasculitis” is characterized by PMNI infiltration with fragmented nuclei as well as …

A

Hypersensitivity reaction to antibiotics, microorganisms or tumor - affects small vessels.

  • no granulomas , P-ANCA in 70% of cases

90% of patients have :

  • necrotizing glomerulonephritis → hematuria,proteinuria
  • pulmonary capillaries→hemoptysis

Q

morphology of pericarditis comes in 2 forms

A

Acute pericarditis

  • Virus/Uremia →“Bread-Butter” fibrinous exudate
  • ​Bacteria → fibrino-purulent exudate
  • ​Malignancy → Bloody effusion

Chronic pericarditis

delicate adhesions →fibrotic scars →contrictive pericarditis

Q

normally , serous fluid in the pericardial sac measures for about 30-50 ml. pericardial effusions exceeding these volumes occur in the following forms …

A

Serous → CHF, hypoalbuminemia

Seroanguinous (serous+blood) → ruptured MI , Trauma , aortic dissection , malignancy

Chylous → lymphatic obstruction

17
Q

a patient previously diagnosed with pericarditis is complaining about atypical chest and dyspnea. his blood pressure was measured and was found to be low. atempts to stabilize his blood pressure with medications failed. this patient may have developed…

A

cardiac tamponade due to fluid accumulation

18
Q

aneurysm is a …

A

abnormal dilation of blood vessel

19
Q

aneurysm are classified as …

A

true aneurysm →involves all 3 layers

false/pseudo aneurysm →breach in vascular wall→hematoma

20
Q

aneurysm can come in two shapes , namely

A

saccular / fusiform

21
Q

name 3 types of aneurysms

A

1) Abdominal Aortic Aneurysm -“AAA”
2) Syphilitic aneurysm
3) Berry aneurysm

22
Q

what are the causes of AAA and where does it usually arise ?

A

Atherosclerosis →compress→necrosis→dilation

Genetic polymorphism in →MMP/ MMPi / inflammatory infiltration

arises between renal arteries above iliac bifurcation

23
Q

what are the 2 types of AAA and my be the consequences of such aneurysms ?

A

Mycotic →bacteria infects atherosclerotic lesions

inflammatory → periaortic fibrosis + inf.inf.

consequences :

thrombosis → ischemia
rupture
embolism
compression on ureter

24
Q

syphilitic aneurysms are caused by which type of spirochaete bacterium?

A

Treponema pallidum →syphillis STD

disease affects vasa vasorumischemia of aortic root media→ scaring →dilation

valvular insufficiency → L.V.H

25
Q

Berry aneurysms are most commonly found in the …and are due to …

A

branching points of arteries in circle of willis

develops due to

congenital malformation + hypertension

if ruptures →intracranial pressure increases

treatment clip it ! or insert spiral metal inside it !

26
Q

aortic dissection is a …

A

intimal tear allows blood to flow to space between intima and media so they separate.

27
Q

what are the causes of aortic dissection ?

A

1) hypertension →old ages
2) atherosclerosis
3) C.T. disorders →young ages → Marfan syndrome

28
Q

how are aortic dissections classified ? what are the consequences of such dissections ?

A

A
Type 1/2 → proximal in ascending aorta

  • type 1 - extensive, ascending +descending
  • ​type 2 - focal, in ascending

B

  • type 3 → distal, in descending aorta

consequences :

1) narrow orifices of blood vessels
2) rupture and bleeding inside body cavities →cardiac tamponade

3) sometimes new channels are formed allowing
* *re-entry** of blood to lumen of aorta →chronic dissection
