Only a few cases of spinal cord compression after cervical laminectomy have been reported. ⋯ This rare complication should be considered among the others after executing a cervical laminectomy.

To explore which preoperative radiologic variables have propensity for reherniation and to evaluate whether the inherent annulus splitting procedure during percutaneous endoscopic lumbar diskectomy (PELD) could prompt reherniation, we assessed the correlation between the anatomic location of annular penetration and reherniation. ⋯ PLL tear and subarticular herniation were significantly related to recurrent disk herniation. Reherniation patterns after PELD generally matched those of primary herniation. The annulus penetrating step during PELD did not increase the risk of reherniation.

Isolated unilateral alar ligament injury (ALI) is a very rarely diagnosed condition, with only 9 cases reported in the literature. The purpose of this study is to determine clinical, diagnostic, and biomechanical features of unilateral ALI. ⋯ Unilateral ALI appears to be more common but misdiagnosed than previously thought. Trauma mechanism consists of hyperflexion and contralateral rotation. Neck pain aggravated with rotation is the most significant clinical finding. Dens lateralization is the most important finding in CT scans. An MRI focusing on the CVJ is essential for the diagnosis. The stability of CVJ must be checked with a flexion-extension CT scan. Unilateral ALI is a stable condition and responds to conservative treatment.

Recent data suggest a favorable benefit/risk ratio for insular glioma surgery. However, it remains unknown if this is also applicable in the learning period of this expertise. Moreover, little is known about the neuropsychological outcomes after resection of insular glioma. ⋯ Resecting insular glioma under brain mapping techniques is a safe option, even during the learning period. Patients should be informed about the risk of mild deterioration of lexical abilities and cognitive flexibility.

To examine changes of expression and activity of phosphodiesterase V (PDE V) in the basilar artery following cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH) in a rabbit model. ⋯ The rabbit model of SAH-induced CVS was successfully constructed through double blood injection method. Increased basilar artery blood flow, narrowing of the basilar artery, increased PDE V expression, and enhanced PDE V activity in the basilar artery were detected in the CVS rabbits, suggesting that PDE V has the potential to be used as a target for CVS therapy.
