Fifty-six patients with 63 aneurysms were selected from a larger group of patients because they had at least one angiographic and one CT scan study. A total of 102 CT scans and 136 angiograms were analyzed. In five patients the aneurysm was visualized on the CT scan. There was a tendency for the location of the subarachnoid hemorrhage and intracerebral hematomas visualized on the CT scans to correlate with the site of the aneurysm as seen on the angiogram. The CT scan was useful in demonstrating the evolution of hydrocephalus and in differentiating hematoma from edema. The patients with normal CT scans were more likely to have good neurological grades. No single angiographic or CT scan feature correlated significantly with survival at lower than the 5 percent level.

Résumé

Résumé

Cinquante-six patients avec 63 anévrismes furent sélectionnés parmi un plus grand nombre de patients ayant eu au moins une étude angiographique et un CT scan. Un total de 102 CT scans et de 136 angiogrammes furent analysés. Chez cinq patients, l’anévrisme fut visualisé au CT scan. La localisation des hémorragies méningées et des hématomes intracérébraux visualisés aux CT scans correspondait au site de l’anévrisme tel que vu à l’angiogramme. Le CT scan est d’une grande utlité pour démontrer l’évolution de l’hydrocéphalie et pour différencier l’hématome de l’édoeme dans les lésions expansives. Les patients avec CT scans normaux étaient plus susceptibles d’être classés comme neurologiquement presque normaux. Aucune des données angiographique ou du CT scan ne correspondait significativement à la survie des patients.
