Which factor does NOT influence whether an occluded vessel will lead to infarction or to tissue survival via collateral circulation?
Show answer and explanation
Correct answer: Colour of the clot
Whether occlusion causes infarction depends on vascular anatomy (single vs dual supply), how quickly occlusion develops (acute vs slow), and tissue oxygen demand; the colour of the clot is irrelevant.
