Surgical relief of progressive upper limb paralysis in Arnold-Chiari

malformation

A Gol and LC Hellbusch

Two cases of delayed progressive paralysis of the upper limbs in an adult

and a teenage patient

without neurological deficits in other regions of the body

are presented. In both cases

the pathology appeared to be a traction lesion of the middle cervical and

lower cervical nerve roots

due to abnormal angulation of the nerve roots

which first ran up and then downward in the neural foramina and canal.

Re-routing of the nerve roots by removing part of the floor of the neural

canal

or by a facetectomy

appeared to offer extensive improvement or full recovery.

Chiari malformation in adults: relation of morphological aspects to clinical

features and operative outcome

JM s, WA Serva, BE Kendall, AR Valentine and JR Ponsford

National Hospitals for Neurology and Neurosurgery, Queen Square, London, UK.

To determine whether clinical features attributed to cerebellar ectopia

could be related to the severity of the malformation, and if morphological

features could be related to operative outcome, a retrospective study of 141

patients with the adult Chiari malformation was carried out, 81 receiving

operative treatment. Morphological parameters derived from preoperative

clinical imaging were compared with presenting clinical features and

postoperative outcomes. Patients with the most severe cerebellar malformation

, defined as descent of the cerebellar tonsils to or below the axis, had

disabling ataxia and nystagmus more frequently. Those with brainstem

compression had limb weakness and muscle wasting more frequently. Operative

outcome was significantly less favourable in patients with severe cerebellar

ectopia (12% improved, 69% deteriorated) than in those with minor ectopia

(50% improved, 17% deteriorated). Patients with a distended cervical syrinx

had a more favourable outcome than those without. Morphological features

help predict operative risk.

Birth injury as a causative factor of syringomyelia with Chiari type I

deformity

K Hida, Y Iwasaki, H Imamura and H Abe

Department of Neurosurgery, University of Hokkaido School of Medicine,

Sapporo, Japan.

The epidemiology of syringomyelia with Chiari type I deformity was

investigated with particular reference to perinatal problems. All subjects

in our study were born by vaginal delivery and had a high incidence of

perinatal accidents (abnormal presentations, birth injuries, and neonatal

asphyxia). This study suggests that these may be strong causative factors

for syringomyelia associated with Chiari type I deformity.
