Pathology Flashcards
What is oedema?
Accumulation of fluid in your body cavities
What is congestion?
Accumulation of fluid within the blood vessels, or tissues and organs
what leads to oedema?
congestion
What is the main driver of both congestion and oedema in the body?
Congestive heart failure
left heart failure leading to left heart failing to pump blood coming from the lungs to the tissues lead to?…
Pulmonary congestion, which leads to pulmonary oedema
Right heart failure resulting in right heart failing to pump incoming blood from inferior and superior vena cava to the pulmonary veins (lungs) leads to?…
Blood vessel, tissue and organ congestion…leading to oedema of these organs
What are the 2 forces leading to edema from congestion?
Increased vascular hydrostatic pressure, and a decreased oncotic pressure
What’s the accumulation of fluid (oedema) occurring throughout the body?
Anarsaca
What’s the accumulation of fluid (oedema) occurring in the peritoneum cavity?
Ascites
What’s the oedema resulting from increased permeability of vesicular blood vessels?
Inflammatory oedema
A form of inflammatory oedema from allergy or hypersensitive reactions?
Angioedema
Oedema of one leg due to deep thrombus formation leading to venous obstruction and increased hydrostatic pressure?
unilateral oedema
What a liver oedema manifested by ascites?
hepatic oedema
Oedema due to obstructed lymph nodes?
Lymphatic oedema
Why do we see lymphatic oedema?
Lymph is obstructed and fails to drain excess fluid from interstitial space
-lymphatic system cn be obstucted by tumours growing within the lympatic vessels, or on tissues nearby thus compressing the lymph vessels, trauma frm severe injury or burns can swell the lymph nodes,, and surgery cn hv imoact
