Air embolism to the cerebral artery circulation is a rare complication previously associated with surgery, scuba-diving, induced abortion, angiography, and pneumothorax. However, air embolism secondary to a ruptured air bulla during commercial air travel has rarely been reported.
We report a patient who became unconsciousness 30 minutes after her plane took off.
The patient was found to have an acute brain infarct in a watershed distribution secondary to multiple, bilateral, intraparenchymal air bubbles. Further investigation revealed a large lung bulla with an air-fluid level.
Air embolism was due to rupture of the lung bulla into the pulmonary venous outflow. Whether the rupture was spontaneous or due to a stretch injury from a change of air pressure resulting in pulmonary barotrauma occurring during commercial air travel is uncertain.
脑动脉循环空气栓塞是一种罕见的并发症，此前与手术、潜水、人工流产、血管造影和气胸有关。然而，商业航空旅行期间因肺大疱破裂继发的空气栓塞鲜有报道。
我们报告一名患者，在飞机起飞30分钟后失去意识。
该患者被发现因双侧脑实质内多个气泡继发分水岭区急性脑梗死。进一步检查发现一个有气液平面的大肺大疱。
空气栓塞是由于肺大疱破裂进入肺静脉流出道。破裂是自发的还是由于商业航空旅行期间气压变化导致肺气压伤引起的拉伸损伤尚不确定。
