  • Paradoxical embolization is, when the formation of thrombotic matter takes place in the venous river, which penetrates the right part of the heart through intracardiac communication (most often foramen ovale) into the artery system and subsequently embolises it (Figures 1 & 2) and (Table 1).

  • Thus, it is termed "paradoxical" because the embolus lands in an artery, rather than a vein. (wikipedia.org)
  • In order for an embolus to become a paradoxical embolus it must traverse from venous circulation, in the veins, to arterial circulation, in the arteries. (wikipedia.org)
  • Often, the embolus will reach the brain and cause permanent stoppage of blood flow to a region of the brain, a feared complication of paradoxical embolism. (wikipedia.org)

  • 15% cases is caudes by embolism, 85% is caudes by arterial thrombosis. (biomedres.us)
  • 15% of cases is caused by embolism, 85% of arterial thrombosis, especially in patients with atherosclerotic disease [1]. (biomedres.us)
  • Although no conclusive evidence has reported a true prevalence of the disease, data suggests that the presence of patent foramen ovales and other inter-cardiac shunts are associated with large increase in the prevalence of strokes of unknown etiology, suggesting paradoxical embolism may be the cause. (wikipedia.org)
  • An embolism is an obstruction in a blood vessel due to a blood clot or other foreign matter that gets stuck while traveling through the bloodstream. (accboise.com)
