Chordoma is a type of rare bone tumor and is a relatively slow-growing, low-grade malignancy that is locally invasive and aggressive. The nomogram is widely used in the field of cancer because it can provide a clear picture for clinicians to predict the survival rate, which can lead more accurate decisions in clinical treatment. ⋯ The nomogram provided more accurate prognostic predictions for patients with spinal chordoma. Moreover, our study suggests that tumor diameter >5 cm, distant metastasis, and not performing resection are major risk factors that can dramatically decrease the survival time of patients with spinal chordoma.

Endovascular coiling is generally considered as an effective treatment option for ruptured intracranial aneurysms. Increasing operator experience and quality of tools determined an improvement of endovascular cerebral aneurysms' treatment. However, procedure-related complications still occur. The purpose of this study is to report a series of rescue stenting procedures with the Neuroform Atlas (NA) open-cell stent, for intraprocedural complications during coil embolization in patients with ruptured intracranial aneurysms. ⋯ The open-cell NA stent represents a rescue option for coil protrusion during endovascular treatment of ruptured intracranial aneurysms allowing regular restoration of blood flow and minimizing thromboembolic events.

Few studies have examined the outcomes of open reduction and internal fixation of vertebral fractures. The purpose of this study was to determine patient-related and surgery-related risk factors associated with 30-day postoperative mortality after open reduction and internal fixation (ORIF) of cervical, thoracic, and lumbar vertebral fractures. ⋯ Pulmonary comorbidity and diabetes were found to be independent risk factors for 30-day mortality after ORIF of vertebral fractures. Recognizing these risk factors is important in preoperative risk stratification, perioperative care, and patient counseling.

The term anterior communicating (ACom) aneurysm is often broadly used to classify any aneurysm formed on the A1-A2 junction, A1, A2, or ACom arteries. Aneurysm location has been associated with rupture risk, so whether an aneurysm is truly formed on the ACom artery can critically affect treatment decisions. The aim of this study was to reclassify broadly termed ACom aneurysms into 4 subgroups (A1, A2, true ACom, and A1-A2 junction) based on their location. ⋯ We found only 13% of the aneurysms initially referred to as ACom to be true ACom aneurysms. A more nuanced approach to ACom aneurysm classification may better guide management strategies.

Prevertebral soft tissue swelling (PSTS) is a known complication of anterior cervical fusion (ACF). Prior studies have shown that perioperative steroids may reduce PSTS after ACF. We retrospectively evaluated the role of perioperative intravenous (IV) corticosteroid administration in minimizing radiographic PSTS measurements in patients undergoing ACF for degenerative disease. ⋯ There does not appear to be a role for perioperative IV steroid administration in minimizing radiographic PSTS in patients undergoing ACF for degenerative disease. The relationship between perioperative IV steroid administration and PSTS requires further investigation.
