Lecture 11 Cardiovascular diseases III Flashcards
Renal infartion etiology:
1) Occlusion of renel artery
2) Ombolism cardiac mural thrombi
2) Embolsim heart valve endocarditis
4) Embolism atherosclerotic plaque aorta
Splenic infarction etiology:
1) Embolism mural thrombis or bacterial endocarditis.
2) Local thrombosis (eg leukemia)
Intestinal infarction:
1) 50 % embolism or thrombus in superior mesenteric artery
2) 25 % embolism in inferior mesenteric artery.
What is an anurysm?
Bulge in vessel as a result of weakening of the media.
Aneurysm etiology:
1) hypertension
2) inherited thin media
3) atherosclerosis.
4) secondary to infection.
The 4 main ways of developing edema:
1) Increased capillary pressure
2) Decreased plasma proteins
3) Reduced lymphatic drainage
4) Increased capillary åermability.
Typer of edema:
1) non-inflammatory. Transudate protein poor. Usually heart failure.
2) inflammatory: exudate protein rich. Increased capillary permability as a result of mediators.
