卵圆孔未闭与高空减压病

目的 回顾近年国外有关心脏卵圆孔未闭（PFO）所致减压时静脉气泡右向左分流，在神经型减压病发病中作用的研究进展。资料来源与选择 国外本领域正式发表的研究论文，综述和会议摘要。资料引用，相互引用，独立引用。资料综合 简要概述了PFO的概念，发生情况，研究意义，重点介绍了国外关于PFO在促进神经型减压病发病中的支持和反对观点，并扼要提出了进一步进行此方面研究应注意的问题。结论 PFO是神经型减压病发生的易发因素之一，但其确切作用还有待进一步研究。此工作对预防高空减压病，认识减压气体栓塞在中枢神经系统损伤中的作用有重要意义。

Patent foramen ovale and altitude decompression sickness

Objective To summarize the studies on the relationship between PFO and the occurrence of neurological ADS in recent years. Literature resource and selection Research papers, reviews and written research reports in this field. Literature quotation Materials were cited mutually and independently. Literature synthesis PFO and its clinical significance in right to left shunts were briefly introduced and the experimental results supported that PFO was a risk factor for cerebral or high spinal ADS, as well as the opposite viewpoints were presented. Things must pay attention to in research of this field were also pointed out. Conclusions PFO is one of the susceptible factors to the occurrence of neurological ADS. But its exact way of action needs further research. It is important to determine whether PFO is a possible risk factor of arterial embolism for the prevention of ADS in pilots and astronauts.
