Myelography with metrizamide--an analysis of the complications encountered in cervical, thoracic and lumbar myelography.

Detailed analysis of complications in 363 patients undergoing myelography with metrizamide is presented. Patients have been separated into three groups: those who had lumbar myelograms via lumbar puncture; patients who had cervical myelograms via lumbar route and patients who had cervical myelograms via cervical puncture (lateral C1/C2. approach). Analysis has revealed that the incidence of minor complications like headaches, nausea, and vomiting is higher than that associated with myodil myelography. Nevertheless, it is concluded that because of lack of long term disability of arachnoiditis, and because of greater diagnostic accuracy, metrizamide represents the best contrast medium for myelography currently available.

Bilateral extracranial internal carotid artery injury due to non-penetrating trauma--report of three cases.

Angiographic features of three patients with bilateral internal carotid artery injury (spasm/dissection/thrombosis) due to non-penetrating trauma are reported. All three patients were involved in motor vehicle accidents. Focal-localizing neurological signs were present and the patients were suspected of having extracerebral haematomas. The diagnosis of traumatic spasm/dissection/thrombosis of the cervical portion of the internal carotid arteries was made following angiography. The need to include views of the cervical carotid arteries in cases of traumatic hemiparesis is stressed and possible effect of cranial CT scanning in these patients on diagnosis of carotid artery injury discussed.

The chest radiograph in ankylosing spondylitis.

In a study of 42 patients with ankylosing spondylitis, upper lobe fibrosis was present in six (14-3%) patients. All the patients with upper lobe fibrosis had total spinal ankylosis, and half showed peripheral joint involvement. A further 13 patients (30-9%) had other focal pulmonary abnormalities compared with only six (14-3%) of a group of age-matched controls. There was no correlation between the radiological extent of the disease (spinal changes and pulmonary involvement) and any of the haematological or biochemical parameters measured. Treatment with radiotherapy was not responsible for these changes.

Pulmonary fibrosis following therapy with Melphalan for multiple myeloma.

A patient suffering from multiple myeloma developed pulmonary fibrosis, of a type known to be associated wtih busulphan, whilst being treated with Melphalan. The possible role of Melphalan as the causative agent is discussed. Reference is made to other possible aetiological agents and the reasons for their exclusion are discussed.

Spontaneous resolution of spinal canal deformity after burst-dispersion fracture.

We reviewed the records of 28 patients with 30 burst-dispersion spinal fractures treated since the introduction of CT facilities in Western Australia. Twenty-five patients showed spinal canal deformity and stenosis with bone fragments protruding into the canal on the initial scan. Of these, 22 patients were treated nonsurgically. Fifteen of the conservatively treated patients were available for follow-up, and they form the basis of this report. Thirteen of the 15 patients who had repeat CT at follow-up showed correction of the previously measured spinal canal stenosis by spontaneous resorption of intraspinal bone fragments. In view of this previously unreported finding, it is suggested that the role of surgical correction of spinal canal stenosis resulting from displaced bone fragments after trauma be more clearly defined.
