A case of fatal cerebral air embolism in a patient with Osler-Weber-Rendu Disease.

Osler-Weber-Rendu syndrome, or hereditary hemorrhagic telangiectasia (HHT), is a rare vascular disorder characterized by arteriovenous malformations (AVMs) in various organs, including the lungs[1]. Pulmonary AVMs (PAVMs) are especially worrisome due to their potential to form right-to-left shunts, resulting in life-threatening complications such as paradoxical embolism and stroke [5] [6] [7]. We present a case of fatal air embolism in a young patient with a known history of HHT and recurring hemoptysis.
