Multicenter Study
Preliminary Analysis of Adjacent Segment Degeneration in Patients Treated with Posterior Cervical Cages - 2 Year Follow-Up.
Select patients with unremitting symptoms of cervical radiculopathy may be treated with indirect foraminal decompression and fusion via placement of a cervical cage placed bilaterally through a tissue sparing, posterior approach. Segmental fusion is known to affect adjacent segments. The aim of this study was to assess the affect of posterior fusion using bilateral cervical cages on adjacent segment degeneration (ASDegeneration) at 2 years postoperatively. ⋯ In the current study, 5.9% of subjects treated with posterior cervical cages placed bilaterally between the facet joints developed adjacent segment degeneration at 2 years. Mild progression of existing degeneration was observed in 11.8% of subjects. Further evaluation to establish long-term incidence is needed.

Review Historical Article
Mythological and Pre-Historical Origins of Neurosurgery.
Mythology has a cultural appeal, and the description of some neurosurgical procedures in the Hindu, Greek, Egyptian, and Chinese mythology has a bearing to the origins of our professions. The traces to some of our modern-day practices also can be linked back to the ancient prehistoric eras of the Siberian, Persian, and the Andean region. In this historical perspective, we briefly dwell into individual accounts through the prism of different cultures to highlight the development of neurosurgery in mythology and prehistoric era.

To investigate the role of endoscopic endonasal transsphenoidal surgery and the pseudocapsule in the treatment of growth hormone adenomas. ⋯ The combination of extra-pseudocapsule resection and endoscopy led to a high rate of gross total tumor resection and endocrinologicl remission in acromegalic patients compared with the group with intracapsular resection. Extra-pseudocapsule resection resulted in no additional postoperative complications.

Medial lenticulostriate artery (MLSA) aneurysms are rare; to our knowledge, only 2 cases without an association with moyamoya disease have been documented. We treated a ruptured dissecting aneurysm of the distal MLSA surgically using a tube retractor. ⋯ There is no definitive strategy to treat distal MLSA aneurysms. Our experience illustrates that natural healing of the vessel wall cannot be expected in all cases. Therefore, less-invasive direct surgical as well as endovascular treatment should not be ruled out in patients with ruptured distal MLSA aneurysms.

To determine the safety and efficacy of endovascular treatment with the Solitaire device for acute basilar artery occlusion (ABAO) and identify factors affecting clinical outcomes. ⋯ Endovascular treatment with the Solitaire device yielded high recanalization rates in ABAO patients and favorable clinical outcomes in approximately one third of patients. Intracranial stenosis was the main cause of occlusion. Angioplasty was commonly performed during mechanical thrombectomy to improve recanalization and prognosis. Early recanalization and better prethrombectomy status predicted better outcomes.
