Learning objectives: Review the literature with respect to aetiology, diagnosis and current treatment options for cerebral air embolism. Describe the radiologic findings that define cerebral embolism and ischemia secundary to arterial occlusion. 

Background: We can define air embolism as the irruption of gas in the circulation (arterial and / or venous), which will result in varying degrees of tissue ischemia. It could be a fatal event occurring usually iatrogenically and an early diagnosis is essential. Air bubbles (and their effects) can be detected [...]

Findings and procedure details: DEFINITION AND ETIOLOGY OF AIR EMBOLISM.   We can define air embolism, as the entrainment of air in the bloodstream (arterial and / or venous), which will cause various degrees of ischemia and tissue suffering in the affected territory. The gas that is introduced into the arterial system will [...]

Conclusion: In the cerebral air embolism the clinical diagnosis may be difficult. Imaging can therefore play a crucial role in revealing the presence of intracranial gas bubbles on CT or MRI scans. Prevention, as well as early diagnosis and management, may reduce morbidity and mortality.
