Inhibition of epidural fibrosis with ADCON-L: effect on clinical outcome one year following re-operation for recurrent lumbar radiculopathy.

In a prospective multicenter study, 20 patients underwent re-operation for recurrent radiculopathy after lumbo-sacral discectomy, and were treated with ADCON-L (Adhesion Control in a Barrier Gel) to inhibit epidural fibrosis following secondary surgery. Outcomes after re-operation were assessed at six and 12 months using: Visual Analog Scales to measure radicular and back pain, straight leg raising exams, and self-assessment of activity-related radicular pain. Each parameter was compared to baseline values, obtained immediately prior to the re-operation. The long term clinical results at 12 months after re-operation (summarized below) demonstrate a significant improvement of all clinical parameters, and correlated with the results seen at six months. Radicular pain, measured when most severe, was reduced from an average pre-operative score of 8.1-3.7 (p < 0.005). The straight leg raising angle increased from an average pre-operative value of 41 degrees-67 degrees (p < 0.005). Activity-related pain mean score was 4.6, vs. 17.0 pre-operatively (p < 0.005). Low back pain, measured when most severe, was reduced from an average pre-operative score of 6.1 to 3.1 (p < 0.012). These clinical findings compare very favorably with data reported in the literature. There were no adverse events or complications related to the use of ADCON-L.

[Craniocerebral trauma and skiing: the ABC of the general surgeon].

This paper describes the classical encephalic lesions due to ski accidents, after a short review of the normal cerebral physiology. It analyses the main steps of the management of the head injury patient by the general surgeon taking history, general and neurologic state, diagnosis, first aid, initial medication, transport conditions and information of the neurosurgical center.

[Treatment of post-traumatic cerebrospinal fluid rhinorrhea with lumbar drainage (author's transl)].

Three patients with CSF-rhinorrhea following frontobasal skull and brain injury were treated with lumbar CSF drainage. Rhinorrhea was successfully stopped in one patient few hours after onset of the drainage while a pneumatocephalus developed in each of the remaining patients during the first post-trauma week. We believe that this latter occurrence was due to depression of intra-cranial pressure as a result of the drainage. As a further consequence of this, risk of intracranial infection increased in association with a hypoliquorrhea, and led to a tentorial pressure cone in one of the patients.

[Cerebellar abscess as an intracranial complication of otogenic origin (author's transl)].

Three cases of otogenic cerebellar abscesses, treated between 1976 and 1978, are reviewed. Early diagnosis is the most important factor in the successful management of these lesions. In localising subtentorial intracranial abscesses, computed axial tomography appears superior to other neuroradiological methods. Lumbar puncture is both inaccurate in diagnosis and dangerous to the patient, when increased intracranial pressure exists.

Angiography of the spinal cord after vertebral trauma.

Angiography of the spinal cord after trauma to the spine is reported in 14 new cases with neurological signs. Three types of angiographic signs are demonstrated: (1) arterial interruption of the anterior spinal artery, the ascending branch of the radiculomedullary arteries or the extravertebral arteries; (2) displacement of the anterior spinal artery without interruption; (3) hyperemia. The mechanism and significance of these signs are discussed.

The microsurgical removal of intramedullary spinal hemangioblastomas. Report of twelve cases and a review of the literature.

From 1969 to 1975, 12 patients were operated upon at the Kantonsspital Zürich by the senior author (MGY) for intramedullary spinal hemangioblastoma with the help of microtechnique. The purpose of this paper is to describe in detail the surgical technique and the results, and to comment on the historical, clinical, pathological, and radiological aspects of spinal hemangioblastoma and the complex of von Hippel-Lindau's Disease (multiple angiomatosis of retina, central nervous system, and viscera) with which it is associated.
