Iatrogenic spinal cord injury (iSCI) during spinal corrective surgery can result in devastating complications, such as paraplegia or paraparesis. Perioperatively, iSCI often occurs as a direct injury during spinal cord instrumentation placement. Currently, treatment of iSCI remains limited to posttraumatic hypothermia, which has demonstrated some value in recent clinical trials. Here we report the outcomes of preinjury hypothermia initiated preprocedurally and maintained for a considerable time after iSCI. ⋯ The use of prophylactic hypothermia before iSCI was significantly associated with an increased survival rate, higher BBB scores, and improved neurophysiological measures.

Intracranial pressure (ICP) reporting impacts neurosurgical care. Millimeters of mercury (mmHg) and centimeters of water (cmH2O) are both used to report ICP in clinical practice and the literature. In this study, we investigated ICP unit of measure awareness in the neurosurgical community. ⋯ Variability and discrepancies regarding the ICP unit of measure exist in academic neurosurgery departments. Clinicians should familiarize themselves with their hospital's practices. Institutions and all of medicine may consider standardizing the ICP unit of measure, using mmHg as a universal nomenclature.

Intraneural hematomas are an uncommon cause of a focal mononeuropathy. When they do occur, it is usually in the setting of inherited or iatrogenic coagulopathies or as a consequence of injections targeting nerves. We report a man aged 68 years on warfarin therapy for a prior pulmonary embolism who presented with a 6-month history of progressive weakness of knee flexion and ankle movement, excruciating pain, and dense numbness in his posterior left thigh and below the knee, consistent with a severe high sciatic palsy. ⋯ The patient underwent surgical exploration, which revealed a thick hemorrhagic pseudocompartment within the sciatic nerve. The histopathologic diagnosis was consistent with chronic hemorrhage. These impressive lesions should be included in the differential diagnosis of nerve masses.

In pediatric cases, the use of autologous bone tissue to repair cranial bone defects is often impossible. The synthetic hydroxyapatite bone substitute (CustomBone) can be a good alternative, especially in case of a large bone defect that has to be repaired. ⋯ The CustomBone implant meets all necessary conditions for good clinical outcome: excellent protective properties, restoration of normal intracranial physiology, satisfactory cosmetic results, good integration in the autologous bone, and good resistance in case of trauma.

We describe a unique anastomosis procedure involving successful middle meningeal artery (MMA) to cortical middle cerebral artery (MCA) bypass, as well as superficial temporal artery (STA) to cortical MCA bypass. ⋯ This is a rare case of successful MMA-to-MCA revascularization to prevent rebleeding in a patient with Moyamoya disease. The MMA can be used as a donor artery for extracranial-intracranial anastomosis procedures in clinical practice settings.
