Background: Revision surgery for patients with persistent, recurrent, or progressive syringomyelia following foramen magnum decompression (FMD) for Chiari malformation I-syringomyelia (CM-SM) is not uncommon and presents both strategic and technical challenges.
Methods: We conducted a retrospective study including all patients who underwent revision Cerebellar Tonsillectomy (CTL) for CM-SM between 2003 and 2023. Additionally, we performed uni- and multivariate analyses to identify possible factors contributing to failed CTL outcomes.
Azygos Vein Stenosis in Frontotemporal Dementia Sagging Brain Syndrome.
AJNR Am J Neuroradiol
January 2025
Ataxia Center, Cognitive Behavioral Neurology Unit, Laboratory for Neuroanatomy and Cerebellar Neurobiology, Department of Neurology (J.D.S., Massachusetts General Hospital and Harvard Medical School, Boston, Massachusetts.
Background And Purpose: Symptoms indistinguishable from behavioral-variant frontotemporal dementia (bvFTD) can develop in patients with spontaneous intracranial hypotension associated with severe brain sagging. An underlying spinal CSF leak can be identified in only a minority of these patients and the success rate of nondirected treatments, such as epidural blood patching and dural reduction surgery, is low. The disability associated with bvFTD sagging brain syndrome is high and, because of the importance of the venous system in the pathophysiology of CSF leaks in general, we have investigated the systemic venous circulation in those patients with recalcitrant symptoms.

Neurosurgery, Al-Azhar University, Giza, EGY.
Intradural disc herniation (IDDH) is a rare condition, accounting for less than 0.5% of herniated disc cases, primarily affecting the lumbar region and often presenting with severe nerve compression or cauda equina syndrome. This paper presents the case of a 60-year-old female with a history of hypertension, dyslipidemia, stroke, and hypothyroidism, who arrived with severe lower back pain, lower limb weakness, and urinary retention.

Orthop Surg
January 2025
Department of Neurosurgery, Xuanwu Hospital, Capital Medical University, Beijing, China.
Background: Iatrogenic cervical kyphosis (ICK) often requires complex anterior and posterior correction, which is associated with multiple complications. Consequently, there is a need to investigate alternative treatment approaches that streamline the operative process and markedly diminish postoperative complications. This study, therefore, aimed to evaluate the feasibility and efficacy of a single-stage anterior controllable antedisplacement fusion (ACAF) in revision surgeries for ICK.

December 2024
Department of Orthopaedic Surgery, The Jikei University School of Medicine, Tokyo, JPN.
Ossification of the ligamentum flavum (OLF) can lead to dural ossification, significantly increasing the risk of complications, including intraoperative nerve injury. The application of augmented reality (AR) and advanced digital technologies in spine surgery has the potential to reduce these risks. This case report highlights a perioperative nerve injury-free microsurgery using elastic image fusion technology, which integrates preoperative imaging with intraoperative computed tomography for a patient with severe stenotic OLF and dural ossification.
