[Compression of the cauda equina by osteoarthritic pseudo-spondylolisthesis, with overlying signs of deficit. The possible role of a venous mechanism].

The authors report the case of a patient suffering from paraparesis where a venous pathology seemed to be responsible, and the literature is reviewed. A cauda-equina compression by L4/L5 arthrosic pseudo-spondylolisthesis caused troubles of the spinal cord venous drainage, seen at the myelography. There was a neurological deficit above the L4/L5 compression with a psoas and quadriceps deficit. After a L4/L5 laminectomy the neurological signs improved rapidly.

Common origin of the arterial blood flow for an arteriovenous medullar fistula and the anterior spinal artery: a case report.

A common origin of the blood supply to a dural arteriovenous malformation and to the spinal cord from the same segmental artery is very rare. This obviously contraindicates embolization of the fistula. Demonstrating the location of the normal spinal blood supply system is therefore mandatory to avoid postoperative complications. The visualization of the normal blood vessels can be masked by a steal phenomenon, but it must at all costs be obtained. The authors describe one such case.

[Marchiafava-Bignami disease with favorable development].

A 35 year-old right-handed woman with a history of alcoholism presented signs of interhemispheric disconnection. CT of the brain revealed a low-density areas in the corpus callosum. Two months later, clinical examination was normal, but the CT showed cystic area in the genu and splenium. MRI was also consistent with a lesion of the corpus callosum. CT and MRI did not show lesions in the hemispheric white matter.

The place of digital intravenous angiography in cerebral infarcts.

The authors describe their technique of intravenous digital subtraction angiography (IVDSA) and discuss the results in cerebral infarcts. IVDSA is a good first stage examination for the recognition of stenosis or occlusion of cervical vessels to the brain, as it is an only marginally invasive and easy technique. It is, however, good neither for the study of focal cervical not of intracranial areas.

Transluminal angioplasty of failing infrainguinal arterial by-pass grafts: initial and long-term results in 13 patients.

Thirteen stenotic infrainguinal arterial bypasses (12 venous, 1 Gore-tex graft) were treated by transluminal angioplasty, either percutaneously (10 patients) or surgically (3 patients). Eleven procedures were immediately successful (two at the proximal portions of femoropopliteal grafts, six near the distal anastomoses, and three at the distal parts of femoroinfrapopliteal grafts) and dilated stenoses are still patent with a mean duration of 24 months in all patients except 2 who died during the follow-up period. The calculated cumulative patency rate is 85% at 36 months. Two procedures were followed by immediate disruption near the distal end of an in situ saphenous bypass graft where balloon inflation was performed. These required immediate surgical repair. Dilatation of the distal ends of in situ saphenous femoropopliteal bypasses may not be as safe as in other locations.

Arterial erosions in acute pancreatitis.

Acute pancreatitis was observed in 492 patients. Fourteen (2.8%) developed an arterial erosion revealed by a haemorrhage either in the digestive lumen, in the peritoneum or via previously placed drainage. The eroded artery was the splenic artery in six patients, a pancreatico-duodenal artery in five patients. An initial haemostasis was attempted by: a) embolization in four patients: one died; the three others had bleeding recurrence. b) splenocorporeal pancreatectomy in four patients, three had bleeding recurrence. c) arterial ligature in four patients: three had bleeding recurrence. Secondary haemostatic procedures were performed in ten patients but a durable haemostasis was achieved in only five patients: two had a pancreatic resection and three were treated by a redo-binding. It is noteworthy that durable haemostasis could not be obtained neither by embolization nor by ligature in necrotic tissues. This could explain the difference in the results of arterial erosion treatments in chronic and in acute pancreatitis. Therefore, it is suggested that haemostatic procedures should be performed away from necrotic tissues, or eventually done after their removal.

[Cervical myelography via lumbar approach. Simple, reliable and painless technic].

A proposal is made to substitute myelography using a lumbar approach for cervical myelography by laterocervical C1-C2 puncture. It is essential for contrast to be injected in procubitus. This examination is simpler to perform, is free from risk and radiologic and diagnostic qualities of images are excellent. This procedure is now used routinely for primary investigation of cervical region and excellent results have been obtained.
