Ventriculostomy-related infection (VRI) is associated with potential serious morbidity, extended hospitalization duration, increased health care costs, and mortality. We assessed the effectiveness of a pragmatic risk-stratification pathway for external ventricular drain (EVD) management, allowing for surgical decision making, in reducing the rate of VRIs. ⋯ The introduction of a pragmatic evidence-based risk-stratification pathway, in which different options for EVD management are incorporated, results in low EVD infection rates across a multisite institutional practice. Our results are comparable to published protocols involving the implementation of standard care bundles and/or antibacterial EVDs alone, in reducing VRIs.

Subdural hygromas are excess fluid accumulations in the subdural compartment, likely occurring via tears in the arachnoid membrane causing cerebrospinal fluid (CSF) leakage into the subdural space. Treatment recommendations for spinal subdural hygromas are lacking. ⋯ Posttraumatic spinal subdural hygromas are rare complications, as evidenced by the lack of literature and treatment guidelines. Using lumbar puncture, we demonstrate clinical and radiographic resolution of a traumatic subdural hygroma. This outcome suggests lumbar puncture may be an effective treatment modality for similar patients, and can potentially be used to avoid a more invasive surgical decompression.

Perioperative embolic stroke is one of the most serious complications during carotid artery stenting (CAS). Proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9i) is a low-density lipoprotein-lowering drug that inhibits proprotein convertase subtilisin/kexin type 9, which normally binds to the low-density lipoprotein cholesterol (LDL-C) receptor. Its combination with statin significantly decreases LDL-C levels. PCSK9i is expected to achieve lower LDL-C levels than single use of statin. This study aimed to investigate whether perioperative PCSK9i administration stabilizes carotid artery plaque and reduces perioperative complications of CAS. ⋯ Lowering LDL-C level could reduce ischemic complications, and low LDL-C level affects plaque stability and antithrombus formation. PCSK9i can possibly stabilize carotid plaque and reduce perioperative complications of CAS.

The sacral dorsal rami form the posterior sacrococcygeal plexus (PSCP), which has been scantly studied. This study's goal was to clarify the PSCP s detailed anatomy and discuss its clinical relevance. ⋯ To our knowledge, this is the first anatomic study that provides detailed images that indicate 3 potential sites where surrounding structures could entrap the PSCP. Knowledge of its detailed anatomy might help in better understanding low-back pain, targeting pain sources and guide spine surgeons for avoiding injury to these nerves.

Malignant craniopharyngioma is a rare clinical entity; most patients with this disease show transformation from an initially benign craniopharyngioma. The rare prevalence of the disease, nonspecific presenting symptoms, and imaging features that overlap with benign craniopharyngiomas make preoperative identification challenging. ⋯ Malignant craniopharyngioma should not be overlooked in patients with a giant sellar mass, especially in young patients who have experienced multiple recurrences of craniopharyngioma and patients who received radiologic therapy.
