A 35-year-old member asked:

What happens if you get a blood clot in the leg (vein), can it cause a stroke (artery)?

Maybe: If you have thrombophlebitis, a clot could go directly to the lung causing a life threatening pulmonary embolism. But if there is a congenital hole within the heart, such as patent foramen ovale, the embolism can be paroxysmal and go to brain, causing a stroke. Anti-coagulation can be protective in these circumstances.
Dr. Michael Schwartz

Rare: In rare cases, there is a communication between the right and left side of the heart allowing a clot from a vein to enter into the arterial circulation called a paradoxical embolism.

If you get a blood clot in the leg, can it cause a stroke (artery)?

Yes: A blood clot in the leg is typically in a vein and if it dislodges it may go to the heart. Most of the time it will pass through the heart and go to the lung. This is known as a pulmonary embolus. In some people it may pass through one side of the heart to the other and then go into the arterial blood system, even to the brain where it may cause a stroke.

Rarely: While it is possible for a vein blood clot to travel to the artery side of things, it would have to do this through a hole in the heart, termed an septal defect. This tests to be rare but can be diagnosed by an ultrasound est looking at the heart. I hope this helps.
