UNASSIGNED: We reviewed the literature using the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines focusing on DAVFs involving the SPS and/or SPV. Additionally, we searched for additional articles through the reference lists of the included studies.
UNASSIGNED: Our review yielded 20 articles from 1997 until 2022 involving 33 patients with 34 fistulas, including our 2 patients. The mean age was 55.1 ± 12.9 years (range 25-85), 54.5% were males (n = 18). The patients presented with hemorrhage in 36.4% (n = 12), and progressive myelopathy in 30.3% (n = 10). Most fistulas often had arterial supply from MMA, MHT, and/or OA. The fistulas had infratentorial drainage in 64.71% (n = 22), supratentorial drainage in 23.53% (n = 8), and both supra and infratentorial drainage in 11.76% (n = 4). In 27.3% (n = 9), cerebral venous thrombosis was mentioned or identified. Endovascular treatment was performed in 47.1% of cases (n = 16), surgery in 29.4% (n = 10), and combination of treatments in 23.5% (n = 8). A total of 30.3% (n = 10) of cases had incomplete recovery or poor result.
UNASSIGNED: DAVFs involving the SPS and/or SPV are associated with aggressive natural history, requiring early diagnosis and prompt treatment, leading to good prognosis. These fistulas may be acquired in origin, probably secondary to cerebral venous thrombosis.
■我们使用PRISMA(系统评价和荟萃分析的首选报告项目)指南对涉及SPS和/或SPV的DAVF进行了综述。此外,我们通过纳入研究的参考文献列表搜索了其他文章.
■从1997年到2022年,我们的评论发表了20篇文章,涉及33例患者和34个瘘管,包括我们的两个病人.平均年龄为55.1±12.9岁(25-85岁),54.5%为男性(n=18)。36.4%(n=12)的患者出现出血,进行性脊髓病占30.3%(n=10)。大多数瘘管经常有来自MMA的动脉供应,MHT,和/或OA。瘘管有64.71%(n=22)的幕下引流,幕上引流率为23.53%(n=8),上及幕下引流占11.76%(n=4)。在27.3%(n=9)中,脑静脉血栓形成被提及或确定。47.1%的病例进行了腔内治疗(n=16),手术占29.4%(n=10),和组合治疗的23.5%(n=8)。共有30.3%(n=10)的病例恢复不完全或效果不佳。
■涉及SPS和/或SPV的DAVF与侵略性自然史有关,需要早期诊断和及时治疗,导致良好的预后。这些瘘管可能是起源获得的,可能继发于脑静脉血栓形成。
