What can happen if an embolus lodges in a vital organ?

When an embolus lodges in a vital organ, it can obstruct blood flow to that organ. This blockage occurs because an embolus is a particle that travels through the bloodstream and can become lodged in narrower blood vessels, interrupting the supply of oxygen and nutrients that the organ requires to function properly.

Reduced blood flow can lead to tissue ischemia, which may cause symptoms ranging from mild discomfort to severe organ dysfunction or even necrosis if the blockage persists. This condition is particularly critical in organs like the brain or heart, where sustained lack of blood flow can result in serious consequences such as a stroke or heart attack. Therefore, the primary effect of an embolus blocking blood vessels in vital organs is a significant reduction in blood supply, potentially leading to severe health risks.
