2016年2月22日 · Operative treatments for TN include microvascular decompression (MVD) and a variety of ablative procedures. With MVD, the compressing or contacting vessel is decompressed or transposed from the trigeminal nerve and permanently separated from the trigeminal nerve, typically with hand-rolled pledgets made of soft material (e.g., shredded Teflon ...

MVD is an effective and safe modality of treatment for TIC and HS. In addition to ruling out structural lesions, MRI can offer additional information by highlighting vascular loops associated with compressions.

2024年5月13日 · Microvascular decompression (MVD) is a widely used neurosurgical intervention for the treatment of cranial nerves compression. Segmentation of MVD-related structures, including the brainstem, nerves, arteries, and veins, is critical for preoperative planning and intraoperative decision-making.

目前的MRI影像学检查可以很好地显示三叉神经和周围的血管情况，并可以进行后处理重建，多方位、多角度观察神经血管的关系，对原发TN的诊断及术前评估起到了关键作用。 CT和MRI有助于明确引起继发性的颅内占位病变…

显微血管减压术(microvascular decompression，MVD)的起源始于针对三叉神经痛(trigeminal neuralgia, TN)外科治疗的临床研究。 数十年的研究结果表明，小脑脑桥角(cerebellopontine angle, CPA)责任血管压迫不同脑神经根进/出脑干区(root entry/exit zoon, REZ)可导致相应症候群，即神经 ...

根據目前的神經血管衝突 (neurovascular conflict，NVC)的發病機理，微血管減壓術（microvascular decompression，MVD）是指在手術顯微鏡下將位於三叉神經、面神經等顱神經根部走行異常、並對顱神經造成壓迫的血管推移開，解除血管對顱神經根部的壓迫，從而使臨床症狀得到緩解。 該方法是當前治療顱內血管壓迫症狀（vascular compression syndromes），可以長時間緩解症狀又可以最大限度的保留神經功能的公認的有效治療方法。 一、MVD的發展史. …

目前临床常用于术前判断颅神经疾病中责任血管的MRI检查为三维时间飞跃扰相稳态梯度回波序列（3D-TOF-SPGR）及三维稳态进动快速成像序列 (3D-FIESTA)。 3D-TOF 影像中动脉、神经、脑脊液等的信号由高到低排列，可以形成明显的对比，用于发现神经与血管的关系及是否存在微血管压迫。 缺点是神经显示比较模糊，而对静脉几乎不能显示。 3D-FIESTA 序列扫描可以将脑脊液显示成极高的信号，而其他组织均为低信号，神经及其周围的结构浸泡在脑脊液中可以形成明显 …

1 天前 · When MRI shows a grade 1 NVC, it can be challenging to determine whether to proceed with MVD. In such cases, it is important to consider the patient’s overall health, clinical presentation, and alternative treatment options [ 20 ].

Microvascular decompression (MVD), also known as the Jannetta procedure, [1] is a neurosurgical procedure used to treat trigeminal neuralgia (along with other cranial nerve neuralgias), a pain syndrome characterized by severe episodes of intense facial pain, and hemifacial spasm.

2023年2月1日 · Accurate preoperative diagnosis of neurovascular compression (NVC) is crucial in microvascular decompression (MVD). NVC can be detected by magnetic resonance imaging (MRI)-based methods. MIF technique based on 3D TOF MRA combined with HR T2WI has better diagnostic performance for detecting NVC.
