Paradoxical embolism due to pulmonary arteriovenous malformations is the main mechanism of brain infarction in patients with hereditary hemorrhagic telangiectasia. International Guidelines have recently been published to clarify the performance of screening tests and the effectiveness of treatment for pulmonary arteriovenous malformations.

Case Presentation

We present two cases of hereditary hemorrhagic telangiectasia patients of our hospital who experienced an acute stroke secondary to paradoxical embolism.


These two cases show that the guidelines must be followed to prevent the occurrence of ischemic stroke in patients with hereditary hemorrhagic telangiectasia, and that although they may be adequate in most cases, there are some patients who need a more personalized approach.
