Spinal epidural abscess is a rare pathology with an incidence that has tripled in the past 2 decades. Ventral cervical epidural abscesses (vCEA) of the cervical spine pose particular treatment challenges because of the anatomical location. The aim of this report is to identify trends in the surgical management of these patients and to determine whether concomitant spondylodiscitis warrants fusion at the index surgery. ⋯ vCEA can be evacuated safely and effectively by a variety of strategies in patients with neurologic deficits. Concomitant spondylodiscitis with cervical epidural abscess may warrant instrumented fusion as part of the initial surgical strategy.

Long-term outcomes are rarely reported for patients with pediatric hydrocephalus. Ventriculoperitoneal shunting is the surgical standard; nevertheless, in selected patients, a ventriculoatrial shunt (VAS) remains an important alternative. This study aimed to analyze the causes of VAS revisions and complications. ⋯ VAS remains an appropriate second-line alternative in selected patients. Specific VAS complications were rarely observed and completely reversible after treatment. However, regular and specific follow-up examinations are strongly recommended to avoid cardiopulmonary or renal complications.

Comparative Study
Comparison of intraoperative CT with postoperative MRI for determining DBS electrode coordinates.
Deep brain stimulation (DBS) is an effective therapy for a variety of refractory movement disorders. Accurate lead placement in the target nucleus is critical to ensure therapeutic effects and to minimize side effects, and intraoperative computed tomography (iCT) scan has been used to target and confirm lead position. The objective of this study is to compare the accuracy of determining the x, y, and z coordinates of final lead placement using iCT scan relative to postoperative magnetic resonance imaging (MRI). ⋯ Significant differences exist between iCT scan and postoperative MRI DBS y and z lead coordinates, but not with x coordinates. Based on this series, iCT scan is more accurate when confirming x coordinates, and less accurate for confirming y and z coordinates during DBS operations.

The necessity and timing of early postoperative imaging (POI) are debated in many studies. Despite the consensus that early POI does not change patient management, these examinations are routinely performed. This is the first prospective study related to POI. Our aims were to assess the necessity of early POI in asymptomatic patients and to verify accuracy of the presented algorithm. ⋯ In asymptomatic postoperative patients in whom early imaging is not performed for oncologic indications, device placement verification, or similar reasons, POI is unnecessary and does not change the management of these patients.

Discal cyst is very rare and can cause intractable low back pain and radiating leg pain. Symptoms are hard to distinguish from lumbar disc herniation. The best treatment for discal cyst is controversial. Most lumbar discal cysts are treated surgically, while most studies of percutaneous transforaminal endoscopic surgery are case reports. This study investigated the clinical value of percutaneous transforaminal endoscopic surgery for lumbar discal cyst. ⋯ Percutaneous transforaminal endoscopic surgery could be a safe, minimally invasive surgical treatment for discal cyst, particularly suitable for patients who cannot undergo general anesthesia.
