Cerebral arteriovenous malformations (AVMs) have been commonly regarded as congenital. However, this suspected origin has been challenged by reports of de novo cerebral AVM. ⋯ The findings from our case report and from 9 similar reports challenge the traditional theory that AVMs constitute congenital lesions.

Management of adolescent idiopathic scoliosis (AIS) in neurosurgery residency training may have a significant impact on resident experience, even though few trainees are likely to pursue careers in the field of AIS. The impact of this exposure on resident knowledge in adult spinal disease management is the subject of our retrospective analysis. ⋯ Treatment of AIS by surgeons with specialized training can be effective and safe. Resident exposure to these patients enhances their understanding of spinal biomechanics and deformity correction, which is applicable to treating AIS and adult spinal deformity.

The angioarchitecture of the spinal cord and microvascular changes after acute and subacute spinal cord injury (SCI) have been reported in rodents. Microvascular changes after chronic SCI have not been explored. We characterized three-dimensional microvascular changes during the chronic phase of cervical hemicontusion SCI in rats. ⋯ Blood supply to the cervical spinal cord is insufficient during the chronic phase of cervical hemicontusion SCI, especially in microvessels with diameters <40 μm. These results may provide a basis to explore microvascular changes of SCI during the chronic phase.

To compare the safety and efficacy between Woven EndoBridge (WEB) embolization and conventional coiling for treatment of unruptured intracranial aneurysms using a propensity score-matched analysis. ⋯ Treatment of unruptured aneurysms with the WEB provides potentially higher aneurysm occlusion rates than conventional coiling while having similar complication rates and no additional morbidity.

Empty sella is an anatomic finding that is usually asymptomatic. However, when patients with empty sella finding present with visual deficits, surgical treatment may be necessary. The main goal of surgery is to elevate sellar content through a transsphenoidal approach. The aim of this study was to demonstrate a new technique for precise reconstruction of the sellar floor using a heterologous bone block to restore the anatomic elements of the sella turcica. ⋯ The technique presented here is simple and reproducible and allows an almost exact and persistent elevation of the sellar content.
