Microvascular decompression (MVD) of the trigeminal nerve is the most effective treatment for trigeminal neuralgia (TN). However, many patients respond poorly to initial MVD. For these patients, redo MVD is commonly done. There has been no research regarding the effectiveness of nerve combing (NC) plus MVD in patients with TN and failed prior MVD. We compared the clinical outcome of NC plus MVD and simple redo MVD in patients with TN and failed prior MVD. ⋯ In patients with TN who failed prior MVD, NC plus MVD significantly improved the success rate of the operation compared with simple redo MVD. We obtained good short-term and long-term surgical outcomes with NC combined with MVD.

Review Meta Analysis Comparative Study
Endovascular thrombectomy alone versus combined with intravenous thrombolysis.
To date, no randomized trial has directly addressed the question of whether intravenous (IV) tissue plasminogen activator (tPA) improves outcomes in IV tPA-eligible patients who will eventually undergo endovascular therapy (EVT), or whether a direct EVT strategy is equally effective. We performed a systematic review and meta-analysis to compare the efficacy and safety of direct EVT versus endovascular treatment with IV tPA (EVT+IV tPA) in adults with acute ischemic stroke. ⋯ No significant differences between the 2 groups were found in terms of favorable functional outcome, mortality rate, or complications based on contemporary endovascular therapies.

Review Case Reports
Remote Thoracic Myelopathy From a Spinal Dural Arteriovenous Fistula at the Cranio-Cervical Junction - Case Report and Review of Literature.
The craniocervical junction is a rare location for spinal dural arteriovenous fistulas (dAVFs). Typically, fistulas at this location present with findings related to intracranial cortical venous reflux or cervical myelopathy. We present a case of craniocervical junction dAVF with isolated clinical and radiographic findings of thoracolumbar myelopathy. ⋯ Isolated lower extremity myelopathic symptoms are a rarely reported finding in patients harboring craniocervical junction dAVFs. At our institution, noninvasive imaging with TR-MRA is routinely used to aid localization of dAVFs. This results in decreased contrast dose and radiation exposure, and inclusion of the cervical spine should be performed when thoracolumbar imaging fails to identify a dAVF prior to proceeding to invasive angiography.

Review Case Reports
Intradural-extramedullary capillary hemangioma with acute bleeding, case report and literature review.
Capillary hemangiomas are benign vascular tumors. They are commonly founded in the vertebral bodies but very seldom in the spinal cord. The most common symptom at onset is long-lasting axial pain without neurologic deficit. In rare cases, the onset may be acute with neurological deficit due to an intratumoral hemorrhage. ⋯ Intradural capillary hemangioma with acute intratumoral hemorrhage is a rare pathology, but it must be kept in mind because early diagnosis and treatment are key to achieve a good outcome. As far as we know, this is the first case reported of an intradural-extramedular capillary hemangioma that presents sudden neurologic deficit due to intratumoral bleeding.

Intradural epidermoid tumors of the spinal cord are commonly associated with spinal cord dysraphism or invasive procedures. We report the particular relationships between spinal subarachnoid compartments and thoracic intradural-extramedullary epidermoid tumor, highlighting the relevant anatomic changes that may influence microsurgery. ⋯ A thorough knowledge of spinal subarachnoid space anatomy is helpful to distinguish between tumor membranes and arachnoidal planes and to achieve a safe and complete resection to avoid recurrences.
