Review of therapeutic failures of microvascular decompression in trigeminal neuralgia at a tertiary hospital.

Introduction: Microvascular decompression (MVD) is a non-ablative technique aimed at relieving pain in trigeminal neuralgia (TN) by resolving a neurovascular conflict. Despite reported high success rates, a significant percentage of patients experience therapeutic failure.

Methods: Retrospective observational study of patients with suspected TN undergoing MVD was performed with the goal of identifying factors contributing to the persistence and recurrence of pain.

Variability of Clinical and Angiographic Results Based on the Treatment Preference (Endovascular or Surgical) of Centers Participating in the Subarachnoid Hemorrhage Database of the Working Group of the Spanish Society of Neurosurgery.

Objectives: Since the introduction of endovascular treatment for cerebral aneurysms, hospitals in which subarachnoid hemorrhage is treated show different availability and/or preferences towards both treatment modalities. The main aim is to evaluate the clinical and angiographic results according to the hospital's treatment preferences applied.

Methods: This study was conducted based on use of the subarachnoid hemorrhage database of the Vascular Pathology Group of the Spanish Neurosurgery Society.

Brown tumor of the orbital roof as an initial and isolated manifestation of secondary hyperparathyroidism.

Brown tumors appear in advanced stages of hyperparathyroidism. Only 17 cases have been documented in the orbit. We report a case of a young woman with a brown tumor in the orbital roof.
