37. abnormal content in the pericardium Flashcards
abnormal effusions of pericardium
transudate - hydropericardium
blood - hemopericardium
exsudate - pericarditis
abnormal solid materials of pericardium
fibrin
blood clots
urate deposits
foreign bodies
abnormal gases of pericardium
air - perforation
other gases - traumatic reticuloperitonitis, ichorous pericarditis
3 causes of hydropericardium
hypoproteinemia
heart failure
vascular injury
why does hypoproteinemia cause hydropericardium
due to decreased colloid osmotic pressure
why does heart failure cause hydropericardium
due to increased hydrostatic pressure
why does vascular injury cause hydropericardium
due to leakage of serum and small quantities of plasma proteins – fibrin strands mat be present
mulberry heart disease is what type of disease
dietary microangiopathy
mulberry heart disease is due to
vitamine e- selenium defieciency in pigs
pathology of mulberry heart disease
fibrinoid necrosis and thrombosis of small vessels resulting in hemorrhages
causing major dicolouration to epicardial surface of right atrium
consequence of mulberry heart disease
discolouration
myocardial degeneraition
cardiac failrue
generalised oedema
hydropericardium
cause of hemopericardium
blunt force trauma
rupture of the wall of teh right atrium
rupture of the intrapericardial aorta or pulomnary artery
iatrogenic (needle)
consequence of hemopericardium
cardiac tamponade - compression of the heart
common tumour of right atrium
hemagniosarcoma
types of epicardial hemorrhages
petechiae
ecchymoses
suffusive hemorrhages
common on coronary groove
