    Notes: Summary 32 cases of negative exploration in a joint follow-up series of 3,032 lumbar disc operations are described. Data from 15 hospitals were analyzed by means of questionnaires and computer-aided analysis. Detailed information is given about pre as well as intraoperative findings. The causes of negative lumbar disc exploration can be divided into two groups. 1. Genuine misdiagnosis where other causes are responsible for the symptoms, and 2. poor technique where despite genuine disc prolapse no evidence was found at operation. The most important causes in the first group were osteochondrotic compression, distended epidural veins, and root tension. The results are less favourable in these patients than in the overall series but, compared to the other complicated courses, the results were markedly better. A review of the literature is given, the possible causes for negative explorations are discussed, and a directive is established for the surgical procedure in cases where an expected prolapse is not found at operation.

    Description / Table of Contents: Zusammenfassung Die Erhöhung des intrakraniellen Drucks bedeutet akute Lebensgefahr. Durch Einführung der direkten Messung des intrakraniellen Drucks werden bedrohliche Druckentgleisungen früher erkannt. Mikrochirurgische Operationsmethoden und Anwendung maßgeschneiderter Clips unter gleichzeitiger kontrollierter Hypotonie machen chirurgische Behandlung von Gefäßmißbildungen risikoärmer. Bei Operation hormonell inaktiver und aktiver Hypophysenadenome senkt transnasaler Zugang Letalitätsrate wesentlich und verbessert funktionelle Ergebnisse. Neue Indiktion in der spinalen Chirurgie: Behandlung der spinalen Claudicatio infolge zentraler Stenose des Spinalkanals durch operative Dekompression der Cauda equina.
    Notes: Summary Increase of intracranial pressure is an acute danger for the patient's life. Since direct measurement of ICP is used, early identification of dangerous dysfunctions of ICP is possible. Surgical treatment of vascular malformations involves less risks since microsurgical methods and “tailor made” clips have been applied together with controlled hypotension. Transrhinoseptal approach in surgery of hormonally inactive and active adenomas has lowered the lethality rate essentially and improved the functional results. New indication in spinal surgery: Treatment of spinal claudication resulting from a central spinal stenosis, by operative decompression of the spinal canal.
