Systemic arterial air embolism following computed tomography (CT)-guided percutaneous lung biopsy: Case series and review of underlying risk factors, treatment and preventive strategies

These cases highlight the importance of prompt recognition and appropriate management of systemic air embolism. Risk mitigation strategies include careful patient positioning, minimisation of intrapulmonary pressure gradients, and maintenance of needle occlusion. Although rare, this complication must be anticipated by interventionalists and managed promptly to avoid permanent neurological damage.
