Current guidelines acknowledge the importance of both microsurgical and neuroendovascular expertise in the treatment of cerebrovascular disease. To achieve optimal care for these patients, it is becoming increasingly evident that procedural volumes impact patient outcomes. This is demonstrated across various cerebrovascular diseases.In this literature review, we demonstrate the association of volume with patient outcomes across multiple cerebrovascular disease states and interventions. Microsurgical aneurysm clipping remains essential even with the rise of endovascular therapy and mortality and patient-safety indicator events are clearly lower at high-volume centers for both ruptured and unruptured aneurysms. Likewise, patients undergoing surgery for cerebrovascular malformations and carotid …

Combined Middle Meningeal Artery Embolisation And Subdural Evacuation Port System Drainage For Chronic Subdural Haematoma: A Systematic Review, Single-Arm Meta-Analysis, Meta-Regression, And Cost-Benefit Analysis, Shiva A. Nischal, Santosh Guru, Shaan Patel, Ashviniy Thamilmaran, Mary Murphy

Department of Neurosurgery Faculty Papers

BACKGROUND: Chronic subdural haematoma (cSDH) is an increasingly prevalent condition in older, anticoagulated, and medically frail patients, in whom recurrence and perioperative risk remain substantial despite standard surgical evacuation. Growing recognition of cSDH as an angiogenic, inflammatory disorder has prompted interest in minimally invasive strategies that combine mechanical decompression with targeted modulation of the underlying vascular pathology. This study aimed to evaluate the safety, effectiveness, and health-economic profile of combined middle meningeal artery embolisation and subdural evacuation port system (MMAE-SEPS) drainage for cSDH, compared with conventional burr-hole evacuation.

In drug-resistant focal epilepsy, planning surgical resection can involve presurgical intracranial EEG (iEEG) recordings to detect seizures and other iEEG patterns to improve postsurgical seizure outcome. We hypothesized that resection of tissue generating interictal high-frequency oscillations (HFOs, 80-500 Hz) in the iEEG predicts surgical outcome. In eight international epilepsy centres, iEEG was recorded during the presurgical evaluation of patients. The patients were of all ages, had epilepsy of all types, and underwent surgical resection of a single focus aiming at seizure freedom. In a prospective analysis, we applied a fully automated definition of HFO that was independent of the dataset. …

Pediatric low-grade gliomas (pLGGs) exhibit heterogeneous prognoses and variable responses to treatment, leading to tumor progression and adverse outcomes in cases where complete resection is unachievable. Early prediction of treatment responsiveness and suitability for immunotherapy has the potential to improve clinical management and outcomes. Here, we present a radiogenomic analysis of pLGGs, integrating MRI and RNA sequencing data. We identify three immunologically distinct clusters, with one group characterized by increased immune activity and poorer prognosis, indicating potential benefit from immunotherapies. We develop a radiomic signature that predicts these immune profiles with over 80% accuracy. Furthermore, our clinicoradiomic model predicts progression-free …
