BACKGROUND: Lumbar fusion is a common treatment for degenerative spine changes. Although both anterior-posterior (AP) and posterior-only approaches are used, their cost-effectiveness remains uncertain. This study aims to compare the costs and short-term "value" (outcomes per dollar spent) of AP and posterior-only lumbar fusions using time-driven activity-based costing and patient-reported outcomes.

METHODS: A retrospective review of AP and posterior lumbar fusions from 2017 to 2022 was conducted. Time-driven activity-based costing was used to assign intraoperative costs based on resource utilization, and the Oswestry Disability Index (ODI) was collected preoperatively and 3 months postoperatively. The Operative Value Index (OVI) was defined …

School of Medicine Faculty Publications

BACKGROUND Intramedullary spinal cord metastasis from local transdural invasion is an exceedingly rare event. Therefore, specific guidance on the timing, type, and extent of surgical intervention is lacking. OBSERVATIONS A 60-year-old male with a known pulmonary neuroendocrine tumor presented with 2 days of progressive lower extremity paraplegia rendering him nonambulatory. MRI demonstrated transpleural and paravertebral invasion by the mass with extension through the left T1–2 and T2–3 neural foramina causing significant epidural compression. There was also transdural invasion at T2 extending intramedullary to the C4 spinal level, with associated cord edema. He underwent posterior cervicothoracic laminectomy and fusion with transpedicular …


Advancing Novel Contrast Agents For Applications In Fluorescence-Guided Neurosurgery Using Fluorescence Cryotomography, Augustino Vittorio Scorzo Jun 2025

Advancing Novel Contrast Agents For Applications In Fluorescence-Guided Neurosurgery Using Fluorescence Cryotomography, Augustino Vittorio Scorzo

Dartmouth College Ph.D Dissertations

Fluorescence guided surgery (FGS) is an emerging surgical technique that aims to help surgeons identify tissue types to assist in surgical decision making - ideally providing “cut-by-color” guidance. A primary application for this approach is the identification of tumor tissue to achieve more accurate and complete tumor removal while simultaneously minimizing damage to surrounding normal tissue. The cornerstone of tumor visualization for FGS is the administration of fluorescent contrast agents, or in some cases metabolic precursors, designed to accumulate specifically in tumor tissue, and a wide range of agents that use different targeting mechanisms are currently under investigation. Although these …

Distinguishing tumor maintenance genes from initiation, progression, and passenger genes is critical for developing effective therapies. We employed a functional genomic approach using the Lazy Piggy transposon to identify tumor maintenance genes in vivo, and applied this to SHH medulloblastoma (MB). Combining Lazy Piggy screening in mice and transcriptomic profiling of human MB, we identified the voltage-gated potassium channel KCNB2 as a candidate maintenance driver. KCNB2 governs cell volume of MB-propagating cells, with KCNB2 depletion causing osmotic swelling, decreased plasma membrane tension, and elevated endocytic internalization of EGFR, thereby mitigating proliferation of MB-propagating cells to ultimately impair MB growth. …

Department of Neurosurgery Faculty Papers

INTRODUCTION: Time-driven activity-based costing (TDABC) is a highly accurate method for determining the true cost of delivering a healthcare service. However, TDABC is most often applied to a singular phase of care such as an outpatient visit or a surgical event. Here we broaden the scope by using TDABC to estimate the costs of surgically treating cervical myelopathy - from the moment of surgical scheduling until post-operative hospital discharge.

METHODS: In a single-center retrospective study at a large tertiary academic institution, TDABC was employed to measure pre-operative, intra-operative, and post-operative (inpatient) costs for 63 patients undergoing elective surgery for cervical …

Glutamatergic Regulation Of Mirna-Containing Intraluminal Vesicle Trafficking And Extracellular Vesicle Secretion From Cortical Neurons, Marcela Bertolio, Qiyi Li, Francesca E Mowry, Kathryn E Reynolds, Rashed Alananzeh, Haichao Wei, Kyoeun Keum, Rachel Jarvis, Jiaqian Wu, Yongjie Yang

Faculty, Staff and Student Publications

Neuronal extracellular vesicles (microvesicles and exosomes) are emerging secreted vesicular signals that play important roles in the CNS. Currently, little is known about how glutamatergic signalling affects the subcellular localisation of exosome precursor intraluminal vesicles (ILVs), microRNA (miR) packaging into ILVs and in vivo spreading of neuronal EVs. By selectively labelling ILVs and exosomes (but not plasma membrane-derived MVs) with GFP-tagged human CD63 (hCD63-GFP) in cortical neurons, we found that glutamate stimulation significantly redistributes subcellular localisation of hCD63-GFP+ ILVs, especially decreasing its co-localisation with multi-vesicular body (MVB) marker Rab7 while substantially promoting EV secretion. Interestingly, glutamate stimulation only modestly alters …

Decompression With Intradural Dissection For The Chiari Malformation Type I: Toward Eliminating Wound Complications, Anna Lin, Lindsey Asti, Marissa Carroll, Jeffrey Campbell, Jospeh Piatt

Department of Neuroscience Faculty Papers

BACKGROUND: There is continuing conversation about surgical technique in the management of the Chiari malformation. Popular options include osseous decompression alone, decompression with dural splitting, and decompression with intradural dissection (DID) and duraplasty. Wound complications after intradural dissection are a persistent problem. The current study of an institutional series examines wound complication rates after intradural dissection without dural closure.

METHODS: A retrospective single-institution chart review was performed for patients < 21 years with Chari malformation type I who underwent DID without dural closure and had at least 6 months of follow-up. Bone removal corresponded to the area of attachment of the rectus capitis posterior minor muscles together with laminectomy of the atlas. The trapezius and semispinalis capitis muscles were retracted but were not separated from the occiput.

RESULTS: A total of 76 patients were treated from May 2010 through May 2024. Thirty-eight (50.0%) patients had syringomyelia. The median age at surgery was 9 years (interquartile range [IQR] 4-13), …

In drug-resistant focal epilepsy, planning surgical resection can involve presurgical intracranial EEG (iEEG) recordings to detect seizures and other iEEG patterns to improve postsurgical seizure outcome. We hypothesized that resection of tissue generating interictal high-frequency oscillations (HFOs, 80-500 Hz) in the iEEG predicts surgical outcome. In eight international epilepsy centres, iEEG was recorded during the presurgical evaluation of patients. The patients were of all ages, had epilepsy of all types, and underwent surgical resection of a single focus aiming at seizure freedom. In a prospective analysis, we applied a fully automated definition of HFO that was independent of the dataset. …

Spetzler-Martin Grade IV arteriovenous malformations (AVMs) are challenging due to high risks associated with both treatment and natural progression. This study compares the outcomes of microsurgical resection and stereotactic radiosurgery (SRS) in high-grade AVMs, analyzing obliteration rates, complications, and functional outcomes. A retrospective cohort of 96 patients treated with either microsurgical resection (33 patients) or SRS (63 patients) was analyzed. Propensity-score matching was employed to account for baseline variables such as AVM size (cm), preoperative embolization and rupture status. Primary endpoints included AVM obliteration, complication rates, and modified Rankin Scale (mRS) scores. After matching, 31 patients per group were analyzed. …

INTRODUCTION: Moyamoya disease (MMD) is a chronic cerebrovascular disorder characterized by progressive stenosis or occlusion of the internal carotid arteries and the development of collateral moyamoya vessels. Surgical revascularization is commonly used to prevent future ischemic events in ischemic-type MMD, but there remains a high rate of stroke perioperatively. This study aims to analyze the predictive factors for perioperative stroke in patients with ischemic-type MMD undergoing surgical revascularization using a large multicenter database.

METHODS: We conducted a multicenter retrospective study in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. This study included patients with ischemic-type …

Research Symposium

Background: An estimated 60% of people that suffer a spinal cord injury (SCI) have a co-occurring traumatic brain injury (TBI), with cervical level injuries having the greatest comorbidity. Following an accident, diagnosis of TBI may be missed as emergency responders prioritize the spinal injury. Early recognition of brain involvement in a patient with a traumatic SCI is crucial, as delayed treatment may cause irreversible neurological impairment such as deficits in concentration, memory, and learning. In this study, we analyzed the comorbidity of TBI and SCI in Texas, and the related demographics and injury characteristics. We aimed to increase awareness of …
