Chronic subdural hematomas (CSDHs) are one of the most prevalent head-trauma-related conditions. The middle meningeal artery (MMA) may participate in the pathophysiology of CSDHs. The aim of this study was to determine whether CSDHs are associated with large MMAs. Patients referred for CSDH embolization and having undergone a computed tomography angiography (CTA) before embolization were retrospectively included. For each CSDH patient, two age- and sex-matched controls with a CTA performed during the study period were selected. Size comparisons of the MMA were performed between MMAs ipsilateral to CSDHs, on the contralateral side, and in controls. Comparison was also made with angiographic measurements from CSDH embolization procedures. Seventy-five patients with CSDH with available CTAs prior to embolization were enrolled and 146 MMAs were measured. One hundred fifty controls were included and 288 MMAs were measured. The median diameter of the 94 MMAs ipsilateral to a CSDH (1.5 mm; interquartile range [IQR] 1.3–1.7) was significantly larger than that of control MMAs (1.28 mm; IQR 1.15–1.4) (p < 0.001). The median diameter of 52 MMAs on the side of a unilateral CSDH (1.6 mm; IQR 1.4–1.8) was larger than that of the 52 contralateral MMAs (1.4 mm; IQR 1.25–1.6) (p < 0.001). Among the characteristics of patients with CSDH, multiple surgeries were associated with significantly larger MMAs (>1.7 mm; p = 0.01). MMAs ipsilateral to CSDHs appear to be significantly larger as compared with contralateral MMAs and MMAs in a control population, suggesting the involvement of the MMA in the pathophysiology of CSDH.

与匹配对照相比,慢性硬膜下血肿患者的计算机断层扫描血管造影术中脑膜中动脉较大。

慢性硬膜下血肿 (CSDH) 是最常见的头部创伤相关疾病之一。脑膜中动脉 (MMA) 可能参与 CSDH 的病理生理。本研究的目的是确定 CSDH 是否与大型 MMA 相关。回顾性纳入了转诊进行 CSDH 栓塞术并在栓塞术前进行了计算机断层扫描血管造影 (CTA) 的患者。对于每个 CSDH 患者,选择了在研究期间进行 CTA 的两个年龄和性别匹配的对照。MMA 的大小比较在 CSDH 的同侧、对侧和对照之间进行。还与来自 CSDH 栓塞手术的血管造影测量值进行了比较。纳入了 75 名在栓塞前具有可用 CTA 的 CSDH 患者,并测量了 146 名 MMA。包括一百五十个对照,测量了 288 个 MMA。CSDH 同侧的 94 个 MMA 的中位直径(1.5 毫米;四分位距 [IQR] 1.3-1.7)显着大于对照 MMA(1.28 毫米;IQR 1.15-1.4)(p  < 0.001)。单侧 CSDH 一侧的 52 个 MMA 的中位直径(1.6 毫米;IQR 1.4-1.8)大于对侧 52 个 MMA(1.4 毫米;IQR 1.25-1.6)(p  < 0.001)。在 CSDH 患者的特征中,多次手术与显着更大的 MMA(>1.7 mm;p  = 0.01)相关。与对照人群中的对侧 MMA 和 MMA 相比,CSDH 同侧的 MMA 似乎明显更大,这表明 MMA 参与了 CSDH 的病理生理学。
