Cervical degenerative disc disease is common in clinical practice. Surgery is among the most effective treatments for patients with cervical radiculopathy, myelopathy, or stenosis. Which treatment is the best option for multilevel cervical degenerative disc disease is controversial. Hybrid surgery, combined cervical disc replacement and anterior cervical discectomy and fusion, may be an alternative treatment for multilevel cervical degenerative disc disease. ⋯ Normal ROM and solid fusion were achieved at both arthroplasty and arthrodesis levels. ROM of replacement levels in different locations of the 3-level construct was acceptable.

The principles of endovascular treatment of bilateral cavernous sinus dural arteriovenous fistula (CS-dAVF) are not well established because of the complexity in the number of fistula tracts and their behavior, which seems to be more aggressive. We aimed to determine an efficient technique for endovascular treatment of bilateral CS-dAVF and the associated factors to achieve good clinical and angiographic outcomes. ⋯ Dangerous venous drainage tends to increase in bilateral CS-dAVF. Retrograde ipsilateral inferior petrosal sinus catheterization using coil embolization and sequencing the embolization are the major concerns for treatment.

Separation surgery is performed to provide a safe gap between the epidural tumor and spinal cord for postoperative stereotactic body radiotherapy (SBRT) in cases of spinal metastases. However, there is a gap in evidence regarding sufficient tumor resection in separation surgery. We describe the prognoses according to the extent of resection in separation surgery. ⋯ Moderate resection of ventral dural mass did not significantly reduce patients' prognosis in separation surgery. However, the minimal distance between the postoperative residual epidural tumor and spinal cord should be ≥3 mm.

Arachnoid cysts are responsible for 1% of expansive lesions in the central nervous system. Usually, they do not cause neurologic symptoms unless they have expansion or hemorrhage. Intracystic bleeding is caused by trauma or may be spontaneous. ⋯ Despite being asymptomatic, the hematoma was determined to have significant mass effect; thus, it was evacuated by a parietal burr-hole. After 1 month, another MRI showed resolution of the frontoparietal hematoma and significant reduction in the arachnoid cyst. There are few cases described of spontaneous rupture of arachnoid cyst; beyond that, we would like to illustrate a step-by-step procedure that is not widely available as a video article.

Coil Occlusion of Right M2 Fusiform Aneurysm After Balloon-Test Occlusion: 2-Dimensional Video.
We present a 73-year-old man with an incidental right M2 fusiform aneurysm demonstrating growth on serial noninvasive imaging over 5 years (Video 1). After multidisciplinary conference review, the decision was to proceed with intracranial balloon-test occlusion (BTO) followed by coil occlusion if the patient passed this test or by trap and bypass if the patient failed this test. With the patient under moderate conscious sedation, a transfemoral 8F approach was used with positioning of a TracStar 95-cm 088 guide catheter (Imperative Care, Campbell, California, USA) into the distal right cervical ICA. ⋯ The patient tolerated the procedure well and was discharged the following day neurologically intact. Six-month follow-up diagnostic angiogram confirmed complete occlusion of the aneurysm. This is the first published video using the elegant approach of intracranial BTO followed by coil occlusion for an intracranial fusiform aneurysm using a dual-lumen balloon microcatheter.
