Arteriovenous malformations in the vicinity of the splenium are a rare cause of subarachnoid bleeding. They are usually unaccompanied by neurological deficits. Three such cases are described and methods of identification and surgical approach discussed. Total extirpation is believed to be the treatment of choice.
A case of acute flaccid paraplegia is reported, due to epidural bleeding in the dorso-lumbar region. A hitherto undiagnosed and asymptomatic hemangioma of a dorsal vertebra was considered to be the source of the haemorrhage. Recovery followed early laminectomy and evacuation of blood clots.
The laser beam can be adapted for use as a surgical cutting instrument. It was chosen for this purpose in the extirpation of an osteoma of the skull. Its removal by conventional means was believed to be too dangerous, because of surrounding vascularity. The nature and properties of the beam and its surgical applications are discussed briefly.
Removal of intervertebral discs and osteophytes with the aid of an operating microscope was performed in ten patients suffering from cervical spondylotic radicular or radiculomyelopathic syndromes, using an anterior approach. The method permits more complete removal of disc, posterior and lateral osteophytes, without the necessity of drilling or otherwise injuring the vertebral bodies. In five patients, a bone graft was inserted into the vacated space after disc removal. Clinical improvement in most cases was immediate and maintained during a two and a half year follow-up.
