【摘要】 目的:通过分析脑膜瘤磁共振表现与复发的关系,研究高压氧对脑膜瘤预后的影响。方法:140例经MRI检查并手术病理证实的脑膜瘤患者资料中有38例经高压氧治疗(高压氧组),余102例未做高压氧治疗(对照组)。分析两组患者中已复发和未复发病例MRI表现的异同以及两组复发率及复发时间的差异。结果:(1)复发组的MRI主要表现为在骨质改变、无包膜、囊性变、强化不均、尾征及瘤周水肿方面与无复发者有区别。高压氧组与对照组比较,各MRI表现无明显差异。(2)对照组102例中,有16例复发,死亡7例:高压氧组38例,有5例复发,2例死亡。P>0.05。(3)两组平均复发时间为39个月和37.6个月,P>0.05。结论:特定的影像学表现与脑膜瘤预后相关,高压氧治疗对脑膜瘤的预后无明显影响。更多还原

【Abstract】 Objective:To investigate the effects of hyperbaric oxygen on the prognosis of intracranial meningiomas by analysing MRI features.Methods:MRI features of 140 cases with meningiomas were compared with prognosis of two groups of patients,38 cases received HBO treatment after surgery(HBO-treated group) and the remaining 102 patients were not subjected to HBO treatment(control group).Results: (1) The MRI features of recurrent patient were different from those of nonrecurrent cases,in the tumour contour,border,intensity after contrast administration,peritumoral edema,and so on.(2) The recurrent rate and motality in HBO-treated group were 5/38(15.2%) and 2/38(5.3%)(?)pectively.And those in control group 15.7%and 6.8%.(P>0.05)(3) The average time of recurrent in HBO group was 37.6 months.39 months in control group.(P>0.05).Conclusoin:Special characteristics are connected with prognosis.HBO is not a factor to influence the prognosis of intracranial meningiomas.更多还原
