Venous Thromboembolism Diagnosis and Management

Pearls• Cerebral air emboli (CAE) are scattered, small, distally located, and characteristically of low density on CT scan.• CAE should be considered as a stroke etiology in appropriate cases.• Prevention is a key treatment strategy. Oy-sters• All techniques that involve positive pressure instrumentation or involve exposure of major blood vessels, especially in patients with suspected cancer or tissue disruption, should be performed with additional caution.• Patient positioning during and after procedures, type of gas used for positive pressure generation, effectiveness of hyperbaric chambers, and identifying anatomical predictors that increase the risk of systemic air embolism are factors that need to be further investigated to minimize morbidity and mortality associated with CAE.
