Development of Common Data Elements for Use in Chiari Malformation Type I Clinical Research: An NIH/NINDS Project.

Neurosurgery 2019 Jan 23. Epub 2019 Jan 23.

Division of Neuroscience, National Institutes of Health/National Institute of Neurological Disorders and Stroke, Bethesda, Maryland.

The management of Chiari I malformation (CMI) is controversial because treatment methods vary and treatment decisions rest on incomplete understanding of its complex symptom patterns, etiologies, and natural history. Validity of studies that attempt to compare treatment of CMI has been limited because of variable terminology and methods used to describe study subjects. The goal of this project was to standardize terminology and methods by developing a comprehensive set of Common Data Elements (CDEs), data definitions, case report forms (CRFs), and outcome measure recommendations for use in CMI clinical research, as part of the CDE project at the National Institute of Neurological Disorders and Stroke (NINDS) of the US National Institutes of Health.

Pilot study of head conformation changes over time in the Cavalier King Charles spaniel breed.

Vet Rec 2019 Jan 11;184(4):122. Epub 2019 Jan 11.

Faculty of Health and Medical Sciences, School of Veterinary Medicine, University of Surrey, Guildford, UK.

Modern interpretation of head conformation in the Cavalier King Charles spaniel (CKCS) has favoured a smaller, more exaggerated, brachycephalic type than originally described in the 1929 breed standard. Recent research studies identified brachycephaly and reduced hind cranium as two conformational (dysmorphic) features that increase risk for symptomatic Chiari-like malformation and secondary syringomyelia (SM). A prospective pilot study investigated the hypothesis that dysmorphic head features could be assessed visually and correlated with risk of SM. Read More

Chiari Malformations.

Acta Neurochir Suppl 2019 ;125:89-95

Department of Neurology and Psychiatry, Division of Neurosurgery, "Sapienza" University of Rome, Rome, Italy.

Background: Chiari malformations (CM) represent a group of anomalies characterized by descent of the cerebellar tonsils or vermis into the cervical spinal canal. These malformations can be associated with abnormalities such as hydrocephalus, spina bifida, hydromyelia, syringomyelia, curvature of the spine (kyphosis and scoliosis) and tethered cord syndrome. Hereditary syndromes and other disorders that affect growth and bone formation-such as craniosynostosis, Ehlers-Danlos syndromes and Klippel-Feil syndrome-can also be associated with CM. Read More

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

J Neurosurg Spine 2018 Nov 1:1-5. Epub 2018 Nov 1.

1Division of Neurosurgery, St. Michael's Hospital, University of Toronto, Ontario, Canada; and.

The pathogenesis of thoracic ventral intradural spinal arachnoid cyst (ISAC) is unknown due to its extremely low incidence. In addition, its surgical treatment is complicated because of the ventral location, large craniocaudal extension, and frequent coexistence of syringomyelia. The optimal surgical strategy for thoracic ventral ISAC remains unclear and continues to be a matter of debate. Read More

Department of Neurological Surgery, Mayo Clinic, Rochester, Minnesota, USA. Electronic address:

Background: Cervical and upper thoracic nerve root avulsions are preganglionic lesions that occur after extreme traction of the brachial plexus. The tearing of the roots from the spinal cord pia leads, not only to immediate and permanent deficits, but also to delayed neurologic complications. Symptomatic myelopathy can present in a late fashion owing to chronic sequelae from the inciting traumatic event. Read More
