概括
在中脑膜动脉栓塞中用于慢性腹腔内血瘤的栓塞材料显示了类似的结果. 颗粒物,Onyx和n-丁烯酸 (n-BCA) 显示了可比的放射性成功率,手术救援率和并发症率.
科学领域:
- 干预性神经放射学 干预性神经放射学
- 血管栓塞是因为血管栓塞.
- 神经外科 神经外科
背景情况:
- 在慢性亚皮血瘤 (CSH) 中,用于中脑膜动脉栓塞 (MMAE) 的栓塞材料的选择缺乏比较数据.
- 有多种栓塞剂可供使用,导致不同的临床偏好.
- 本研究解决了对CSH的MMAE中不同栓塞材料进行比较分析的需求.
研究的目的:
- 为了比较MMAE中用于CSH的不同栓塞材料的疗效和安全性.
- 评估结果,包括放射成功,需要救援手术和重大并发症.
- 提供数据,以告知未来的临床试验设计和材料选择.
主要方法:
- 这是一项多中心的回顾性研究,对872名从2018年至2023年为CSH接受MMAE的患者进行了研究.
- 根据栓塞物质分组患者:颗粒物,奥尼克斯或n-丁烯酸 (n-BCA).
- 倾向性得分匹配 (PSM) 用于比较材料组之间的结果,控制临床变量.
主要成果:
- 在三个组中,手术救援率 (9.8% vs 7% vs 11.7%),放射性成功率 (78.8% vs 79.3% vs 77.4%) 或重大并发症 (2.4% vs 2.3% vs 2.5%) 没有显著差异.
- PSM分析证实了这些发现,显示了颗粒和液体栓塞 (Onyx和n-BCA组合),以及特定液体剂之间的可比结果.
- 某些程序特征,如全身麻醉和双边栓塞,在颗粒组中更频繁.
结论:
- 栓塞材料的选择 (颗粒,石,n-BCA) 并没有显著影响放射学改善,手术救援或MMAE对CSH的重大并发症率.
- 研究结果表明,颗粒物是MMAE中CSH的液体剂的可行替代品.
- 目前以液体栓塞为重点的随机试验,如果包括粒子栓塞,可能会产生类似的结果.

Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
