Emergency medical assistance is rare regarding air travel. Pulmonary barotrauma during air travel can occur in asymptomatic patients who have underlying intraparenchymal pulmonary pathology such as bullae or bronchogenic cysts. During aircraft travel the resultant decrease in pressure during the ascent can lead to expansion of cyst volume, culminating in tears and leakage of air into the surrounding vasculature and thus the potential for air embolism. We describe a case of massive cerebral air embolism secondary to pulmonary barotrauma in a previously asymptomatic patient.
航空旅行中很少提供紧急医疗援助。在无症状的患者中，可能会出现肺实质内的肺部病理学，如大疱或支气管源性囊肿，从而导致航空旅行中出现气压下降导致囊肿体积膨胀，最终导致破裂和空气漏入周围血管，从而有发生空气栓塞的潜在风险。我们描述了一例先前无症状的患者因肺气压伤导致的大量脑空气栓塞的病例。
