Recurrence is one of the concerns even after successful endovascular treatment of intracranial aneurysms. We sought to determine the critical aneurysm volume and risk factors related to aneurysmal stability in patients undergoing coil embolization of intracranial aneurysms. ⋯ In our series of cerebral aneurysms treated with coil embolization, 500 mm3 was found to be the critical volume determining stability after coil embolization. Large volume aneurysms in the posterior circulation were especially prone to recanalization after coiling.

Comparative Study
Comparison of clinical and radiological characteristics and prognosis of chronic subdural hematoma patients with and without a history of head trauma.
To compare clinical and radiologic characteristics and prognosis of patients with chronic subdural hematoma (CSDH) with and without a history of head trauma. ⋯ Patients with CSDH with or without a history of head trauma presented with different clinical and radiologic characteristics. Patients with CSDH without a history of head trauma had a higher mortality and lower GOS score, which indicates these patients warrant more attention.

To assess the in vivo longitudinal kinematic performance of the Prestige-LP Disc and describe the 5-year trends in the center of rotation (COR) at the instrumented level. ⋯ Single-level CDA with the Prestige-LP Disc achieved favorable clinical outcomes and provided a durable solution for spinal motion at the instrumented level. The COR showed a significant cranial shift after surgery and remained relatively stable during the 5-year follow-up period.

Few reports have focused on chronic subdural hematoma (CSDH) in the very elderly, who have lived beyond average life expectancy. Our aim is to appraise treatment outcomes of burr-hole craniotomy for CSDH in the elderly, focusing on cure, recurrence, and complications. ⋯ With advancing age, CSDH might show a greater tendency to recur and a longer time is required to achieve a cure. However, complications developed only in high-risk patients. Thus, surgical treatment for CSDH in elderly patients, even those who have lived beyond life expectancy, might provide acceptably effective results.

Anterior cervical discectomy and fusion (ACDF) is the most common procedure for single-level cervical spondylotic myelopathy (CSM); however, for multilevel CSM, some patients may also undergo anterior cervical corpectomy and fusion (ACCF). We sought to assess differences in clinical outcomes between patients undergoing ACDF and those undergoing ACCF for multilevel CSM. ⋯ Our analyses indicate that ACCF may be associated with worse clinical outcomes than ACDF following multilevel treatment for CSM.
