This one seemed tough to me after my first 'lucy' read:
Q3 A 25-year-old man presents with headache, dizziness, and claudication. Blood pressure measurements reveal
hypertension in the upper limbs and hypotension in the lower limbs. Which of the following additional findings
would be most likely in this case?
A. Aortic valvular stenosis
B. Notching of inferior margins of ribs
C. Patent ductus arteriosus
D. Pulmonary valvular stenosis
E. Vasculitis involving the aortic arch

Hi Dreams,
Please quote the question you are answering. Click on the #(number) at the top right corner for quoting.
At this point its obvious you are answering my questions. But down the lane, this quoting habit will avoid chaos.
Thanks,

Two questions - (apart from - is my answer right?)
Is the site of infarction different for Thrombus v/s Embolus?
Is the propensity for thrombus formation same throughout the gut circulation, and thrombus at any other site doesn't cause infarction, but thrombus at splenic flexure causes infarction because of watershed phenomenon?

2. No Infarction is most likely to be in place where there is inadequte blood floow. So its not the whole but a few particular areas. Usually where ever the circulation is good the vessels are large the thrombi goes forward. It has to get lodged in place where there is no blood flow to move and the all hell breaks lose. Similar patter in Lungs and Brain. It doesnt go and block the big vessel it go after the tiny ones. The only thing which blocks the bigger blood vessels is Atherosclerosis but this also in combo with a large thrombus but all the great vessels or larger vessels have adaptive mechanisms to overcome such issues.
