Hypothyroidism is widely thought to cause vascular endothelial disorders and atherosclerosis. The purpose of this study was to explore whether patients with hypertension and hypothyroidism may have a higher incidence of hypertensive intracerebral hemorrhage. ⋯ Hypothyroidism may be independently associated with hypertensive intracerebral hemorrhage. In view of the known pathophysiologic relationship between hypothyroidism and vascular endothelial dysfunction and atherosclerosis, further research and exploration are necessary.

The suboccipital midline approach is common dealing with posterior fossa tumors but has a high risk of postoperative complications, such as pseudomeningocele, cerebrospinal fluid (CSF) leak, and meningitis. Neurosurgeons used various kinds of method to lower its rate. ⋯ Applying the cervical fascia autograft to reconstruct the dura during posterior fossa surgery is a simple and effective method to reduce the rate of meningitis as compared with artificial dura mater.

Despite advancements in surgical techniques, controversy remains regarding the optimal implant density for the correction of idiopathic scoliosis. Recent evidence has suggested that equivalent radiographic and clinical outcomes can be achieved with lower implant densities for those with moderate curves and good flexibility. Among the experts, the consensus has continued that higher implant densities should be used for larger, stiffer curves. The purpose of the present study was to compare the radiographic results between high-implant density (HID) and low-implant density (LID) constructs in patients with large (>65°), rigid (<50% flexibility) curves who had undergone anterior release and posterior spinal fusion. ⋯ In patients with large, rigid idiopathic scoliosis undergoing anterior release and posterior spinal fusion, a small, but statistically, significant improvement in the coronal Cobb angle was seen. It remains to be determined whether this small difference in radiographic correction will have any influence on the clinical outcome.

Overshunting-Associated Myelopathy Treated with Endoscopic Third Ventriculostomy: A Case Report.
Overshunting-associated myelopathy (OSAM) is a rare complication of cerebrospinal fluid shunt placement. Previous reports have recommended removal or ligation of the shunt and use or revision of a pressure programmable valve to treat OSAM. We present a rare case of OSAM successfully treated with endoscopic third ventriculostomy (ETV). ⋯ This is the first case of OSAM treated with ETV. ETV might be a useful treatment option for OSAM after treatment for obstructive hydrocephalus.

We report a case of cervical radiculopathy caused by an anomalous vertebral artery (VA) and the efficacy of endovascular vertebral artery sacrifice. ⋯ Cervical root compression by an aberrant or anomalous extracranial VA is a rare cause of radiculopathy. Endovascular VA sacrifice provided symptom relief in our patient, when other options failed. To our knowledge, this is the first report of endovascular VA sacrifice for management of cervical radiculopathy due to VA loop.
