Cohort Study of Multiple Brain Lesions in Sport Divers:Role of a Patent Foramen Ovale BMJ 314:701-705, 6891997., Knauth,M.,et al, 1997 See this aricle in Pubmed Article Abstract Twenty-five subjects were found to have a right-to-left shunt,13 with a patent foramen oval of high haemodynamic relevance.A total of 41 brain lesions were detected in 11 divers.There were seven brain lesions in seven divers without a right-to-left shunt and 34 lesions in four divers with a right-to-left shunt.Multiple brain lesions occurred exclusively in three divers with a large patent foramen ovale(P=0.004).Multiple brain lesions in sport divers were associated with presence of a large patent foramen ovale.This association suggests paradoxical gas embolism as the pathological mechanism.A patent foramen oval of high haemodynamic relevance seems to be an important risk factor for developing multiple brain lesions in sport divers.
