Veins In Heart Blocked
Depends: Coronary steal from unligated side branches from the left internal mammary artery (lima) when it is used for coronary bypass is an area of open debate. Most surgeons will ligate a large side branch to prevent the possibility of steal, small branches are often not (the risk of ligating higher than the liklihood of steal). The exact size that requires ligation to prevent steal is unknown. ...Read moreSee 1 more doctor answer

Why compressing both left and right common carotid arteries leads to brain death when vertebral arteries(and also circle of willis) still supply .
Carotid occlusion: The vertebral arteries are not enough to sustain the entire blood brain perfusion. They contribute to the anterior circulation by means of the posterior communicating arteries. There are common anatomical variants and in some cases these arteries are not patent or existent.
