为双侧延髓梗死者,而单侧延髓背外侧梗死预后均改善,少数留下轻微后遗症,未见到双侧延髓背外侧梗死病例。有文献统计38例双侧延髓内侧梗死患者住院期间病死率23.8%;致残率61.9%4。而延髓背外侧梗死只有合并严重感染或其他并发症时可能引起预后不良,极少数报道单纯延髓背外侧梗死累及呼吸导致死亡病例。总之,延髓部位梗死的预后与梗死部位密切相关,延髓内侧及双侧延髓梗死者预后差,单侧延髓梗死及延髓背外侧梗死预后相对较好,合并肺内感染和其他部位梗死可加重病情,对预后不良。参考文献[1]ChoiHS;ParkSC;LeeYS;etaLLateralMedullaryInfarctionPresentingwithVertigewithoutotherNeurologicalsigns.OtolaryngolHeadNeckSury.2012V147N6:1162-3.[2]Nozakil;YamadaM.Aneasydiagnotictooldistinguishinglateralmedullaryinfarctionfromperipheralvertigo.ClinNeurolNeurosury,2012V114N1:68-9.[3]SeoMJ,RohSY,KyunYS,etal.DiffusionWeightedImagingFindingsintheAcuteLateralMedullaryInfarctionJournalofClinicalNeurology.Volume2,June,2006:107-108.[4]PongmoragotJ;ParthasarathyS;SelchenD;SaposnikG.BilateralMedialMedullarylnfarction:ASystematicReview」StrokeCerebrovascDis.2012Apr25.
