Ventral Thoracic Spinal Cord Herniation: Clinical Image and Video Illustration of Microsurgical Treatment.
World neurosurgery, 2020Co-Authors: Joshua Bakhsheshian, Ben A. Strickland, John C. LiuAbstract:Idiopathic Spinal Cord herniation is a rare cause of progressive myelopathy that can result in severe disability. In the following report, an illustrative case and associated video in the surgical management of ventral Thoracic Spinal Cord herniation is presented and discussed. Spinal Cord herniation is most commonly observed in the Thoracic spine and is characterized by ventral displacement of the Spinal Cord through a defect in the dura. Over time ventral herniation of the Spinal Cord can compromise its vascular perfusion, resulting in further ischemic injury. The etiology is unclear, but suspected to be either acquired or congenital. Multiple surgical techniques have been reported with the goal of detethering the Cord and taking adjunctive measures in reducing the risk for re-herniation. Surgical management of Thoracic Spinal Cord herniation carries great risks, although neurological outcomes are generally favorable with improvements reported in the majority of cases.

Release and repair of a ventral Thoracic Spinal Cord herniation
Neurosurgical Focus, 2014Co-Authors: Paul C. MccormickAbstract:Ventral Thoracic Spinal Cord herniation is a rare but increasingly recognized cause of progressive myelopathy. This video demonstrates the imaging characteristics and surgical techniques for release and reduction of the Spinal Cord herniation as well as primary repair and reinforcement of the ventral dural hernia defect through an extended posterior approach. An instrumented fusion was concomitantly performed. The video can be found here: http://youtu.be/6Pcokep6Tug.

Spontaneous Thoracic Spinal Cord herniation. A case report.
Spine, 1996Co-Authors: Panayiotis Sioutos, Ehud Arbit, Peter Tsairis, Ruth GarganAbstract:Study Design This is a case report. Objective To focus attention on spontaneous Spinal Cord herniation as a rare cause of myelopathy that can be diagnosed preoperatively and can be corrected surgically. Summary of Background Data A 34-year-old woman presented with spastic paraparesis. Magnetic resonance imaging scan of the Thoracic spine revealed anterior displacement and tethering of the Cord at T6-T7 and a dorsal intradural arachnoid cyst. Excision of the cyst was performed without improvement in symptomatology. During reoperation the Thoracic Spinal Cord hernia was discovered and was reduced intradurally. Methods The authors describe the clinical, radiographic, and surgical findings of this patient and review the findings from other reported cases. They discuss the proposed theories for the pathophysiology of the Cord herniation and the surgical management. Results The patient had idiopathic Thoracic Spinal Cord herniation as there was no history of previous spine surgery or injury. The authors believe that the Cord herniated through a congenital dural defect, which resulted in the development of a pseudoarachnoid cyst dorsally to the hernia. The patient improved after intradural reduction of the hernia and closure of the dural defect. Conclusion Idiopathic Spinal Cord herniation should be recognized as a cause of progressive myelopathy that can be managed successfully with microsurgical techniques.

Spontaneous Thoracic Spinal Cord herniation : Three cases with long-term follow-up
Neurosurgery, 2005Co-Authors: Kevin Ammar, Patrick R. Pritchard, Paul G. Matz, Mark N. HadleyAbstract:OBJECTIVE AND IMPORTANCE: Spontaneous Thoracic Spinal Cord herniation (STSCH) is an uncommon cause of Thoracic myelopathy. Fewer than 40 cases have been reported in the English language literature with a mean follow-up of less than 6 months. CLINICAL PRESENTATION: We have encountered three patients diagnosed with STSCH in the last 6 years at our institution. These patients presented with symptoms and signs localizing to the Thoracic Spinal Cord. Magnetic resonance imaging revealed ventral Thoracic Spinal Cord displacement in each. INTERVENTION: One patient was treated surgically, two managed expectantly. Two patients have been followed for greater than 5 years, whereas a third has been followed for 15 months. CONCLUSION: Our experience suggests that patients with neurological symptoms and signs attributable to STSCH may not progress and therefore may be followed with clinical and magnetic resonance imaging surveillance. When surgery is indicated for progressive STSCH, late retethering may occur.
