Atlanto-axial injuries pose a significant threat to morbidity and mortality. This retrospective study aims to analyze clinical and radiological results, failure rates, and complications in a series of patients treated with a halo vest, validating the effectiveness of this device through long-term follow-up. ⋯ Based on our results, the halo vest is a valid treatment for atlanto-axial injuries in selected patients. This includes young and middle-aged individuals (up to 65 years old) with C1 and/or C2 fractures. Halo vest treatment is associated with minor complications and yields a high percentage of excellent/good clinical results.

There are many studies on post-operative cognitive function after surgical clipping (SC) and endovascular coiling (EC) for unruptured cerebral aneurysms, but few reports focusing on possible subclinical damage. The aim of the present study was to detect the subclinical damage after surgical intervention. ⋯ 123IMP-SPECT revealed a statistically significant reduction in ipsilateral CBF in patients who had an uneventful clinical course and no cognitive problems. The subclinical consequence could persist for at least 2 years following SC, and was less pronounced following EC.

The plasticity of the Circle of Willis represents an underexplored yet intriguing dimension of vascular anatomy in cerebrovascular disorders. We outline distinct patterns of change in response to aneurysm treatment using flow diversion (FD) after covering major branches. ⋯ The circle of Willis displays both hemodynamic and anatomic plasticity after major branch coverage with a flow diverter. This phenomenon is aimed at preserving blood flow in the distal territory of the covered vessel.

Unplanned reoperation post-spinal surgery (URPS) leads to prolonged hospital stays, higher costs, decreased patient satisfaction, and adversely affects postoperative rehabilitation. This study aimed to develop and validate prediction models (nomograms) for early URPS risk factors using machine learning (ML) methods, aiding spine surgeons in designing prevention strategies, promoting early recovery, reducing complications and improving patient satisfaction. ⋯ The established model can effectively predict URPS in patients and can assist spine surgeons in devising personalized and rational clinical prevention strategies.

Thoracic dorsal arachnoid webs are intradural membranes that may cause obstruction of CSF flow and spinal cord compression. While well-recognized, they are rare and there is a paucity of long-term data on their natural history and prognosis. We reviewed radiographic features, surgical indications, and pathologic specimens of patients diagnosed with focal thoracic dorsal arachnoid webs. ⋯ The majority in a large series of patients with dorsal arachnoid webs did not undergo surgical intervention, but those with myelomalacia and syrinx experienced radiographic and clinical deterioration without surgery. Surgery to treat symptomatic arachnoid webs results in significant clinical improvement with low surgical morbidity.
