Staged treatment of brain arteriovenous malformations (AVMs) is sometimes necessary to minimize risks associated with sudden changes in cerebral hemodynamics. With the increasing availability and optimization of endovascular techniques, multiple surgical resections are rarely necessary, although, due to specific anatomic circumstances, some AVMs still require staged surgery. Here, we describe the largest reported series of staged surgical resections of brain AVMs. ⋯ Staged surgical resection of large and complex AVMs can be performed with good outcomes in carefully selected patients.

Coronavirus disease-2019 (COVID-19) pandemic had a great impact over all elective neurosurgical activity and important implications in management of neurosurgical urgencies. During the pandemic, some pediatric hospitals reported their experiences. After the emergency phase of the COVID-19 pandemic, the health care system needs to be reorganized to again manage all nonurgent activities, while ensuring safety of both patients and health care workers. ⋯ The Italian health care system is undertaking a process of reorganization of resources, in an attempt to restore all nonurgent activities while ensuring safety. After the emergency phase, we are learning to live together with COVID-19 and, although epidemiologic data are encouraging, we must be prepared for an eventual second peak.

This report analyzes the significance of osteophytes in the overall pathologic scheme in patients with single-level or multilevel cervical spinal degeneration. ⋯ Spinal stabilization reduces the size of osteophytes. Facet distraction spacers are more effective in reduction of the size of DOL in both immediate and delayed postoperative periods.

Glioblastomas (World Health Organization grade IV) are aggressive primary neoplasms of the central nervous system. Spinal metastasis occurs supposedly in 2%-5% of patients. This percentage may be only the tip of iceberg because most succumb to the disease before clinical detection and few documented cases are reported. ⋯ Spinal and dural metastasis should always be suspected in patients with glioblastoma with signs and symptoms not explained by primary lesion. A regular protocol with postcontrast magnetic resonance imaging before and after initial surgery is mandatory to detect spinal metastasis before it becomes clinically apparent, thereby improving the prognosis and quality of life in patients.

The modified iliac screw fixation technique was proposed to be an interesting alternative option for spinopelvic fixation. In this study, we describe a new minimally invasive technique for percutaneous placement of modified iliac screws. ⋯ The modified iliac screws can be placed safely via percutaneous approach with an intraoperative image guidance. By using this new technique, surgeons can easily adjust the screw head to align with S1 pedicle screw via the same small incision. The rod connectors are not necessary for this technique. This method also prevents the acute angle that can develop between the screw head and shaft of the screw, which is typically found in S2 alar-iliac screw technique.
