What Is the Definition of Paradoxical Embolism?

Q:
What is the definition of paradoxical embolism?

A:
Paradoxical embolism, also called crossed embolism, is a kind of stroke or other form of arterial thrombosis caused by embolism of a thrombus, air, tumor, fat, or amniotic fluid of venous origin.

Paradoxical embolism refers to an embolus which is carried from the venous side of circulation to the arterial side, or vice versa.

The embolus that blocks the artery travels to the arterial side through a lateral opening in the heart, such as a patent foramen ovale, or arteriovenous shunts in the lungs.
