    Description / Table of Contents: Résumé Compte tenu de la situation de l’anévrysme, les auteurs étudient 173 cas de spasme artériel cérébral avec rupture anévrysmale unique. Par rapport à la situation de l’anévrysme, le spasme se trouvait davantage dans le domaine de l’artère communicante antérieure ou de l’artère cérébrale moyenne mais ceci n’était pas le cas pour les anévrysmes de l’artère communicante postérieure. L’association d’hydrocéphalie et de spasme a été trouvée dans des cas cliniques sévères. Statistiquement, le spasme était plus visible sur les artériogrammes tardifs tandis que l’hydrocéphalie était visible aussi bien sur les artériogrammes précoces que sur ceux plus tardifs.
    Abstract: Zusammenfassung Beschreibung von Untersuchungsergebnissen von 173 Patienten, bei denen eine Aneurysma-Blutung nachgewiesen wurde. Der Spasmus wurde mit der Lokalisation des Aneurysmas verglichen, er fand sich besonders bei Aneurysmen im Bereich der A. communicans anterior und der A. cerebri media, nicht jedoch bei Aneurysmen der A. communicans posterior. Die Kombination des Spasmus mit einem Hydrocephalus fand sich bei schweren klinischen Krankheits-Syndromen.
    Notes: Summary The distribution of localised cerebral arterial spasm in 173 cases of single leaking aneurysms has been plotted with respect to the site of the aneurysm, and significant correlations found for anterior communicating and middle cerebral aneurysms, but not for posterior communicating aneurysms. The presence of hydrocephalus and spasm were found to be associated with the clinical grading of severity, but not with each other. Spasm was seen with statistical significance more often in later arteriograms, but hydrocephalus was seen in the earlier arteriograms as frequently as in the later ones.

    Notes: abstract Objective To determine the prognostic value of multimodal evoked potentials (EPs) and eventrelated (ERPs) potentials in coma (Glasgow Coma Score 〈8), after severe traumatic brain injury (TBI). Design Prospective, longitudinal study of neurophysiological responses recorded during traumatic coma. Setting Intensive Care Unit, Frenchay Hospital, Bristol, UK. Participants Fifty-four comatose TBI patients (age range 1–80 years, mean 36.4). Methods Neurophysiological responses were recorded from 11 scalp electrodes with earlobe reference. Conduction times were measured for brainstem auditory, flash visual and somatosensory, shortlatency EPs. Peak latencies and amplituides were determined for long-latency components of visual and auditory ERPs, generated by passive “oddball” paradigms. These neurophysiological and various clinical parameters were correlated with patient outcome using Pearson's coefficient. Main outcome measure Three month Glassgow Outcome Scale (GOS). Results and conclusion Highly significant (P〈0.001) correlations exist between long-latency ERP components and 3-month outcome. Short-latency EPs, brainstem (wave I–V) and somatosensory conduction times, also correlate significantly with the GOS (P〈0.01). Of the clinical measurements, pupillary response patterns, APACHE II and Glasgow Coma Scores (GCS) correlate significantly with outcome, as do the retrospective measures of duration of coma and post-traumatic amnesia (PTA) in survivors. Unfortunately, due to variance of long-latency responses, even in controls, absolute values cannot be relied upon as prognosticators. The presence of “mismatch negativity” predicted the return of consciousness (89.7% sensitivity and 100% specificity) and preceded changes in GCS. Its latency was the single best indicator of 90-day outcome from coma (r=−0.641).
