aortic dissection Flashcards
what are the symptoms of aortic dissection ?
severe central tearing chest pain (really bad) that may radiate through the back
sudden onset
may mimic renal colic
collapse
risk factors for AD ?
having an AAA (lol)
being a man
being old
being a smoker
being obese
having a FHx of AAA
having Marfan’s
hypertension, hyperlipidaemia, atherosclerosis
what are the two classifications for AD ?
Stanford and DeBakey
what is the stanford classification ?
standford type A = aortic dissection in the ascending aorta
standford type B = descending aorta (this one has no end-organ ischaemia)
management for standford type B ?
medical ie
IV beta blockade, analgesia
maybe vasodilators to bring HPT down
management for standford type A ?
open replacement / endovascular intervention
before = BP should be controlled, with a target of 100-120mmHg
what is the DeBakey classification ?
type I - originates in the ascending aorta, and moves distally
type II - originates and is confined to the ascending aorta
type III - originates in the descending aorta
investigations for AD ?
CXR - widened mediastinum
CT angiography - false lumen
complications of AD ?
backwards tear:
aortic regurgitation
MI - inferior/right coronary
forwards tear:
unequal arm pulses and BP
stroke
renal failure
