Randomized Controlled Trial
The Effects of Intermittent Whole-Body Hypoxic Preconditioning on Patients with Carotid Artery Stenosis.
To study the effects of intermittent whole-body hypoxic preconditioning on patients with carotid artery stenosis. ⋯ Intermittent hypoxic preconditioning can change the vital signs and hematologic indexes of patients with carotid artery stenosis without causing new postoperative complications or organ damage.

Utility of 3-Dimensional-Printed Models in Enhancing the Learning Curve of Surgery of Tuberculum Sellae Meningioma.
To investigate the value of 3-dimensional (3D)-printed models with pathologic entities in enhancing the learning curve of surgery of tuberculum sellae meningioma. ⋯ 3D-printed models can assist in improving the learning curve of surgery of tuberculum sellae meningiomas. It particularly aids in memorization and spatial construction, improves understanding of surgical view, and arouses interest on the part of the trainee. We recommend using it in the education of complex skull base surgery.

To present diagnosis and surgical management of postlaminectomy spondylolisthesis in patients without preoperative instability and a review of relevant literature. ⋯ In patients without overt pre-existing instability, laminectomy for lumbar stenosis can disrupt spinal stability and result in iatrogenic spondylolisthesis. The extent of decompression of the facet joints, number of levels decompressed, and preoperative disc space height can help assess the risk of postoperative spondylolisthesis. Patients who develop recurrent radiculopathy after decompressive lumbar laminectomy should be evaluated for potential iatrogenic spondylolisthesis.

To assess the mid-long-term follow-up of the safety and efficacy of anterior cervical discectomy and fusion (ACDF), cervical artificial disc replacement (CADR) and hybrid surgery (HS) for bilevel cervical degenerative disc disease (cDDD). ⋯ HS was superior to ACDF with regard to equivalent clinical outcomes in the mid-long-term follow-up. Furthermore, HS was superior in the maintenance of ROM and had less impact on its adjacent segments. The efficacy of HS is similar to that of CADR.

Crossing a nascently deployed carotid artery stent (CAS) is required to perform angioplasty and filter recapture. If the traversing balloon or filter recapture catheters are eccentric or tangentially angled to the vertical axis of the CAS, they can ensnare on the ledge of the proximal CAS step-off, potentially causing life-threatening complications secondary to deformation, displacement, or mechanical occlusion of the stent. We report a novel "balloon bridge" technique that facilitates safe entry and passage across the CAS with both a balloon catheter and a large-bore guide catheter (LBGC). ⋯ Traversing a CAS with an LBGC or balloon catheter can be tedious and fraught with the potential of neurologic peril should mechanical deformation and occlusion occur. The balloon bridge technique is safe and highly effective for navigating a catheter that is eccentric or tangentially angled to the long axis of a CAS.
