脑膜瘤的软脑膜血供与瘤周水肿形成的相关性研究

Correlative research of pial blood supply to meningiomas and formation of peritumoral edema

目的探讨脑膜瘤的软脑膜血供与其瘤周水肿形成的关系。方法回顾性分析1997年2月～2005年2月该科手术治疗并经病理证实的60例脑膜瘤患者,所有患者均有脑血管造影和头颅CT资料。脑膜瘤的供血类型和位置通过脑血管造影来确定,瘤周水肿的位置通过头颅CT来确定,再将两者的空间位置关系加以整和分析。结果脑膜瘤的软脑膜血供与瘤周水肿的相关性通过χ2检验(P=0.000)具有统计学意义,且其位置基本符合(符合率92.593%)。结论脑膜瘤的软脑膜血供与瘤周水肿的形成有密切的关系。

[Objective] To study the relationship between the pial blood supply to the meningiomas and the formation of peritumoral edema. [Methods] We retrospectively analyzed 60 patients with primary intracranial meningiomas at different locations who were treated at our neurosurgy department, covering the period from 1997 to 2005. All the patients were treated surgically and the diagnosis of the meningiomas were confirmed by postoperative pathology. Computed tomography and angiography were performed in all patients preoperatively. The vascular supply and the location of peritumoral edema were recorded according to evaluation of the cerebral angiograms and cerebral CT data respectively. And then we integrated and analyzed the spatial relationship of the two. [Results] Statistical analysis （χ^2 test） demonstrated that the peritumoral edema was significantly related to the pial blood supply （P =0.000） as well as the location of pial blush （the ratio of concordance 92.593%）. [Conclusion] Pial blood supply may have an important role in development of the meningioma peritumoral edema.
