ok, i'm still confused.
"because branch vessels may be occluded by the false lumen or by emboli, blood pressure differences between arms of 15-20 mm hg may be present and should be sought"
"a thoracic aneurysm can affect blood supply to the left subclavian artery, the large branch that leads to the left arm"
so does that mean because the emboli is big, the blood pressure is different? or blocked? i'm a literal girl, i need to understand the pathophysiology of why this happens, and can't find it on the web anywhere.
first of all know the flow of blood in the heart:
first it enters the vena cava then right atrium down to right ventricles and the rv pumps the blood to the lungs through pulmonary artery then it goes back to heart from the lungs and it is now oxygenated. it enters the heart via pulmonary veins in the left atrium and then down to the left ventricles, the lv pumps the blood to aorta.
aneurysm = a sac and maybe ruptured if too much pressure is put..
aorta = largest artery
in short aortic aneurysm is a sac in the aorta which can be ruptured and cause internal bleeding may cause decrease amount of blood circulating the vascular space so the person will have a fvd and therefore a low bp and high hr as compensatory mechanism which can lead to shock and if not treated promptly will result to death..
p.s. if you think i miss something or its incorrectly stated pls do some reply. i'd be happy to receive some comments. thank you and i hope that helps you alwayslearningrn
