Systemic Air Embolism After CT-guided Lung Biopsy

Plain-language summary

Systemic air embolism is traditionally considered as an extremely rare complication of percutaneous lung biopsy. Current literature includes mainly case reports or small case series of SAE. Majority of cases resulted in cardiac and/or neurological symptoms, often causing death. In most reported cases, the diagnosis of systemic air embolism referred to clinical manifestations without radiological diagnosis at the time of the procedure. Hence, its incidence might be underestimated in case of asymptomatic patients. Immediate recognition of air embolism during the procedure has been reported as the main factor to minimize severe complications since specific management of patient can be initiated earlier. The purpose of this study is to retrospectively assess the incidence of systemic air embolism depicted at the time of the procedure on a whole thoracic CT, systematically performed after transthoracic lung biopsy in a large cohort of consecutive patients. Secondary objectives are to determine possible influencing factors and to evaluate clinical outcomes.
