Cerebellar tonsil ectopia measurement in type I Chiari malformation patients show poor inter-operator reliability.

Fluids Barriers CNS 2018 Dec 17;15(1):33. Epub 2018 Dec 17.

Department of Biological Engineering, University of Idaho, 875 Perimeter Drive MS 0904, Moscow, ID, 83844-0904, USA.

Background: Type 1 Chiari malformation (CM-I) has been historically defined by cerebellar tonsillar position (TP) greater than 3-5 mm below the foramen magnum (FM). Often, the radiographic findings are highly variable, which may influence the clinical course and patient outcome. In this study, we evaluate the inter-operator reliability (reproducibility) of MRI-based measurement of TP in CM-I patients and healthy controls. Read More

Treatment failure of syringomyelia associated with Chiari I malformation following foramen magnum decompression: how should we proceed?

Neurosurg Rev 2018 Dec 15. Epub 2018 Dec 15.

Departments of Neurosurgery and Pediatric Neurosurgery, Tel-Aviv Medical Center and Dana Children's Hospital Tel Aviv, Tel Aviv University, 6 Weizmann Street, Tel Aviv, Israel.

The preferred treatment of patients with persistent, recurrent, or progressive syringomyelia after foramen magnum decompression (FMD) for Chiari I (CMI)-associated syringomyelia is controversial, and may include redo FMD, stabilization, or shunting procedures (such as syringopleural or syringo-subarachnoid shunts). We describe our experience in treating these patients and discuss the treatment modalities for these patients. We retrospectively collected data of CMI patients with persistent, recurrent, or progressive syringomyelia after FMD. Read More

Clinical Application of Diagnostic Imaging of Chiari-Like Malformation and Syringomyelia.

Front Vet Sci 2018 28;5:280. Epub 2018 Nov 28.

School of Veterinary Medicine, Faculty of Health & Medical Sciences, University of Surrey, Guildford, United Kingdom.

Chiari-like malformation (CM) and syringomyelia (SM) is a frequent diagnosis in predisposed brachycephalic toy breeds since increased availability of MRI. However, the relevance of that MRI diagnosis has been questioned as CM, defined as identification of a cerebellar herniation, is ubiquitous in some breeds and SM can be asymptomatic. This article reviews the current knowledge of neuroanatomical changes in symptomatic CM and SM and diagnostic imaging modalities used for the clinical diagnosis of CM-pain or myelopathy related to SM.

Fourth ventricle stent placement for treatment of recurrent syringomyelia in patients with type I Chiari malformations.

Authors:

J Neurosurg Pediatr 2018 Oct 1:1-7. Epub 2018 Oct 1.

OBJECTIVEIn patients with syringomyelia and type I Chiari malformation (CM-I) who have required reoperation because of persistent, recurrent, or expanding syrinx, the senior author placed a stent from the fourth ventricle to the cervical subarachnoid space in hopes of promoting circulation of CSF out of the ventricle and away from the central canal of the spinal cord. This study was undertaken to determine the long-term success of this operative stratagem in eliminating the syrinx, as well as to document the complications that occurred following stent placement. The technique utilized for placement of fourth ventricle stents is presented. Read More

Cervico-medullary compression ratio: A novel radiological parameter correlating with clinical severity in Chiari type 1 malformation.

Clin Neurol Neurosurg 2018 Nov 10;174:123-128. Epub 2018 Sep 10.

Ministry of Health, Health Sciences University, Diskapi Yildirim Beyazit Training and Research Hospital, Department of Neurosurgery, Ankara, Turkey.

Objectives: Chiari malformation type 1 (CM-1) is associated with cough headache, intracranial hypertension, cerebellar and spinal cord symptoms/signs. Herniated cerebellar tonsil length (HCTL) is widely used radiological parameter to determine the severity of CM-1, but with limited utility due to its weak correlation with some clinico-radiological findings. In this study, we aimed to evaluate a novel, practical parameter (cervico-medullary compression ratio; "CMCR") for its relationship with clinico-radiological findings in CM-1. Read More

Effectiveness of modified dural incision to preserve the patency of the occipital sinus in foramen magnum decompression for a patient with Chiari malformation type I.

Surg Neurol Int 2018 3;9:153. Epub 2018 Aug 3.

Department of Neurosurgery, Graduate School of Medical Science, Kanazawa University, Takara-machi, Kanazawa 920-8641, Japan.

Background: Foramen magnum decompression (FMD) has been acknowledged as a standard surgical procedure for symptomatic patients with Chiari malformation type I (CM-I). However, even if dural incision is necessary during FMD, the procedure of cutting off the occipital sinus has not been regarded as a safe option.

Case Description: A 27-year-old woman with intractable occipital headache was diagnosed with CM-I without syringomyelia. Read More

Dura-splitting versus a combined technique for Chiari malformation type I complicated with syringomyelia.

Br J Neurosurg 2018 Aug 27:1-5. Epub 2018 Aug 27.

a Department of Neurosurgery, Affiliated Nanjing Brain Hospital , Nanjing Medical University , Nanjing , People's Republic of China.

Background: Surgical approaches for Chiari malformation type I (CM-I) complicated with syringomyelia (SM) are controversial, so we assessed the efficacy and safety of two widely used procedures.

Methods: We retrospectively analyzed results from posterior fossa decompression (PFD) using bony decompression with dura-splitting or a combined technique (duraplasty with arachnoid dissection and coagulation of the herniated tonsils) for CM-I associated with SM between Jan 2008 and Feb 2016. Patients were followed up for at least one year. Read More

The Treatment of Cleidocranial Dysostosis (Scheuthauer-Marie-Sainton Syndrome), a Rare Form of Skeletal Dysplasia, Accompanied by Spinal Deformities: A Review of the Literature and Two Case Reports.

Case Rep Orthop 2018 9;2018:4635761. Epub 2018 Jul 9.

Department of Orthopaedics, Okan University Hospital, Istanbul, Turkey.

Cleidocranial dysostosis is a skeletal dysplasia inherited in an autosomal dominant manner and may lead to complications such as scoliosis and kyphosis, concurrent with various orthopedic involvements. Since concurrent spinal deformities are of progressive nature, surgical treatment may be necessary. In addition to other orthopedic problems, possible accompanying complications such as atlanto-axial subluxation, myelopathy, syringomyelia, congenital spine deformities, spondylosis, and spondylolisthesis should be kept in mind while planning for the treatment of scoliosis and kyphosis.

Fluid dynamics in syringomyelia cavities: Effects of heart rate, CSF velocity, CSF velocity waveform and craniovertebral decompression.

Neuroradiol J 2018 Oct 17;31(5):482-489. Epub 2018 Aug 17.

2 Department of Radiology, University of Wisconsin, USA.

Purpose How fluid moves during the cardiac cycle within a syrinx may affect its development. We measured syrinx fluid velocities before and after craniovertebral decompression in a patient and simulated syrinx fluid velocities for different heart rates, syrinx sizes and cerebrospinal fluid (CSF) flow velocities in a model of syringomyelia. Materials and methods With phase-contrast magnetic resonance we measured CSF and syrinx fluid velocities in a Chiari patient before and after craniovertebral decompression. Read More

Front Vet Sci 2018 27;5:171. Epub 2018 Jul 27.

Department of Veterinary Medicine, Faculty of Health and Medical Sciences, University of Surrey, Guildford, United Kingdom.

Chiari-like Malformation (CM) and secondary syringomyelia (SM), as well as their analogous human conditions, is a complex developmental condition associated with pain and accompanying welfare concerns. CM/SM is diagnosed ever more frequently, thanks in part to the increased availability of magnetic resonance imaging in veterinary medicine. Research over the last two decades has focused primarily on its pathophysiology relating to overcrowding of the cranial caudal fossa. Read More
