Transradial access has been described for mechanical thrombectomy in acute stroke, and proximal balloon occlusion has been shown to improve recanalization and outcomes. However, sheathed access requires a larger total catheter diameter at the access site. We aimed to characterize the safety of sheathless transradial balloon guide catheter use in acute stroke intervention. ⋯ Sheathless radial access using a balloon guide catheter may be safely performed for acute ischemic stroke with excellent radiographic outcomes. Further investigation is warranted to evaluate the comparative effectiveness of sheathless compared with sheathed transradial balloon guide access.

Giant thoracic disk herniations are calcified hernias that fill >40% of the spinal canal and result in myelopathy with associated neurologic symptoms. This is a fairly rare abnormality that requires surgical treatment. Currently, there is no unambiguous opinion about the surgical approach to the treatment for this pathology. It is believed that the most effective method is the anterior approach (minithoracotomy or thoracoscopic approach), which reduces the risks of spinal cord injury but is associated with the risks of damage to the lungs, pleura, and major vessels. A giant thoracic disk herniation is also quite large. ⋯ The minimally invasive dorsal approach in the surgery of giant thoracic herniated disks can be successfully used in neurosurgical practice. With this approach, it may be possible to avoid dorsal stabilization, but this requires additional research.

To compare postoperative opioid morphine milligram equivalents (MME) prescriptions for opioid-naïve patients undergoing single-level transforaminal lumbar interbody fusion (TLIF) versus posterolateral lumbar fusion (PLF) and total postoperative MME prescribed based on operative duration. ⋯ Opioid-naïve patients undergoing single-level TLIF receive a greater number of postoperative opioids than patients undergoing single-level PLF, and TLIF was an independent predictor of increased postoperative opioid prescribers, prescribers, and MME. There were no differences in postoperative opioid prescriptions when assessing patients based on operative duration.

Aqueduct stenosis is a recognized cause of obstructive hydrocephalus in children and can be treated effectively with endoscopic third ventriculostomy. Preoperative magnetic resonance imaging is often diagnostic of the cause of aqueduct stenosis. ⋯ We believe these 2 reported cases demonstrate a previously unreported phenomenon whereby concealed tectal gliomas presenting with hydrocephalus are only unmasked following relief of hydrocephalus and decompression and normalization of the ventricular system. We aim to raise awareness about this unusual phenomenon and recommend routine postoperative interval imaging following endoscopic third ventriculostomy to avoid missing underlying pathology masquerading as aqueduct stenosis.

Mesenchymal stem cells (MSCs) have been shown to enhance neurological recovery after stroke. A rat middle cerebral artery occlusion model was designed to assess neuroprotective effects of stroke pretreated MSCs on cerebral ischemia/reperfusion injury. ⋯ Administration of SS-MCSs after reperfusion led to neuroprotection by inducing the recovery process, including improving pathological changes, behavioral improvement, neurogenesis, suppression of apoptosis and inflammation, and angiogenesis.
