liver lobule
functional unit of the liver
blood pathway through the liver lobules
blood goes through the afferent arterioles, moves through the lobule and starts to flow with hepatocytes
S&S of hepatic disease
jaundice
cirrhosis
what does liver inflammation cause
tissue damage and necrosis
PT implication
portal vein
conveying blood to the liver from the spleen, stomach, pancreas, gall bladder and intestines
what pressure system does the portal vein have and what is the result of that
low, so it can affect spleen, stomach, pancreas, gall bladder and intestines when its damaged
where does the portal vein conduct blood from
SI to capillary bed in the liver - not a true vein
portal vein HTN =
increase in BP >6mmHg
hepatic system function
MSK location of pain from hepatic disease
posterior thoracic pain - inter scapular, R shoulder, R upper trap, R subscapular
if you have fibrosis and an abnormal liver, what happens
a mechanical barrier to blood flow forms and increases resistance in the hepatic portal system
increased portal pressure causes what
retrograde flow of blood back into the stomach, spleen, large and small intestine, rectum and esophagus
what does an increase in portal pressure result in
varices, abnormal dilated vessel
consequences of portal vein HTN
hepatic encephalopathy
symptoms of hepatic encephalopathy
stupor
decerebrate posturing
positive babinski’s
dilated pupils
PT implications for hepatic encephalopathy
pt safety
impaired motor and sensory integrity
risk for pressure ulcers - secondary to malnutrition, immobility and edema
ascites
abnormal accumulation of fluid in peritoneal cavity
- cirrhosis, PV HTN
implications for ascites
accompanying impaired cardiac and respiratory fxn
muscle degradation
viral hepatitis
hepatitis A
