Intraoperative Ultrasound: Real-Time Surgical Adjunct for Complete Resection of Spinal Arachnoid Webs.

Spinal arachnoid webs are abnormal formations of arachnoid membranes that reside in the arachnoid space. Clinically, they may present as an incidental finding or in patients with progressively worsening myelopathy. Early detection and surgical intervention are recommended in patients with progressive symptoms. Several methods have been described for the surgical treatment of these web formations.1-4 The success of surgery and the ability to prevent recurrence is dependent on complete surgical resection of these lesions, which in some cases can appear complex and intricate in nature. A few reports have highlighted the use of intraoperative ultrasound to localize the lesion; however, none have highlighted its value in establishing successful web resection and restoration of normal cerebrospinal fluid flow.3,4 Herein, we demonstrate the use of intraoperative ultrasound as an effective adjunct to assessing and establishing complete resection of arachnoid webs. We illustrate how intraoperative ultrasound allows for real-time, direct visualization of arachnoid lysis with restoration of normal cerebrospinal fluid flow (Video 1). Our patient was symptomatic for 12 months with rapid progression of myelopathic symptoms in the 3 months before presentation. Following surgery, she remained asymptomatic at 4-year follow-up with no reoccurrence at 24-month magnetic resonance imaging. Intraoperative ultrasound is a useful adjunct to successfully performing dorsal arachnoid web surgery and ensuring improved surgical outcomes through complete web resection and decompression of the spinal cord.

Traumatic bilateral lumbosacral facet dislocation without fracture: illustrative case.

BACKGROUND: Traumatic bilateral lumbosacral facet dislocations without fractures are extremely rare. Only 7 cases have been documented since the first description by Watson-Jones in 1974. Although various treatment strategies have been reported, no consensus has been reached regarding the best surgical approach. OBSERVATIONS: A 35-year-old female presented for medical attention following a high-speed motor vehicle collision. She sustained multiple injuries, including an abdominal aortic injury requiring emergent thoracic endovascular aortic repair. She was found to have bilateral lumbosacral dislocation without fracture (L5-S1) and was noted to be neurologically intact. Once medically stabilized, the patient was taken to the operating room for minimally invasive reduction and stabilization of her lumbosacral spine. Postoperatively, the patient was neurologically intact and remained stable with no deficits and appropriate lumbosacral alignment throughout her 2-year follow-up. LESSONS: The authors report a minimally invasive approach to the management of bilateral lumbosacral facet dislocation without fracture. Although conventional open approaches have been described previously, consideration should be given to minimally invasive strategies in select patients to facilitate their rehabilitative postoperative course.

Examining mental health stigma in a first-year seminar for student veterans.

Objective: To examine perceptions of mental health stigma among first-year student service members/veterans (SSM/Vs). Participants: 107 SSM/Vs enrolled in a first-semester seminar completed a pre- and post-test measuring five constructs; 1) stigma toward mental health in the military, 2) academic readiness, 3) mental health stigma in college, 4) connection to campus, and 5) resiliency. Methods: Data were analyzed using paired samples t-tests to measure growth on the scales of interest, along with a multiple regression analysis to establish predictors of growth. Results: Stigma-Military and Connection to Campus increased while Stigma-College reduced (p<.05). For the regression analysis, statistically significant predictors of stigma include number of deployments and having served in a combat role (p<.05) Conclusions: Results suggest classroom interventions for SSM/Vs on campus may be related to reduced stigma toward mental health services. This study provides a starting point for expanding research on health and wellness curricular interventions for SSM/V.
