A bench study was performed to investigate the potential of air bubbles entering a central vein via a central venous catheter to ascend retrograde to the brain. The results support the hypothesis that air bubbles may rise retrograde against the venous blood flow, depending on bubble size, central vein diameter and cardiac output. A review of radiological findings in published case reports indicates that the occurrence of retrograde cerebral air embolism is underestimated.
进行了一项实验台研究，以调查气泡通过中心静脉导管进入中心静脉后逆行至脑部的可能性。结果支持了这样的假设，即气泡可能会逆着静脉血流逆行上升，这取决于气泡大小、中心静脉直径和心输出量。对已发表病例报告中的放射学结果进行回顾表明，逆行性脑空气栓塞的发生率被低估了。
