Such an event is termed a paradoxical embolism.

This was known as a paradoxical embolism.

Paradoxical embolisms represent two percent of arterial emboli.

Clinically it is linked to decompression sickness, paradoxical embolism and migraine.

Blood clot that travels from the lungs to the arms, legs, or brain (paradoxical embolism)

PFO has long been studied because of its demonstrated role in some cases of paradoxical embolism.

In 1880 Litten documented one of the earliest known cases of a paradoxical embolism in a patient undergoing anaesthesia.

In paradoxical embolism, also known as crossed embolism, an embolus from the veins crosses to the arterial blood system.

The paradoxical embolism then reaches the cortex, triggering cortical spreading depression, a phenomenon that leads to migraines.

In paradoxical embolism, a deep vein thrombosis embolises through an atrial or ventricular septal defect in the heart into the brain.

A paradoxical embolism is a kind of stroke or other form of arterial thrombosis caused by embolism of a thrombus (blood clot) of venous origin through a lateral opening in the heart, such as a patent foramen ovale.

On the other hand, when there is a hole in the wall between the two upper chambers of the heart (an atrial septal defect), a clot can cross from the right to the left side of the heart, then pass into the arteries as a paradoxical embolism.
