The results of a prospective cooperative study on aneurysmal subarachnoid hemorrhage (SAH) in Japan, 1994 (PCS-Japan 94) are reported. Eleven neurosurgical centers participated in this study over Japan and a total of 525 patients were entried and followed up for 3 months. The results were compared with those of International Cooperative Study on Timing of Aneurysm Surgery (ICSTAS) reported in J Neurosurg by Kassell, et al. in 1990.
In PCS-Japan 94, more aged patients and cases in serious condition (WFNS Grade, IV, V) were enrolled. The overall outcome of these 525 cases were as follows by Glasgow Outcome Scale (GOS): GR, 56.7%; MD, 9.9%; SD, 8.6%; PVS, 4.6%; D, 20.2%. These results are almost the same as those of ICSTAS. This is possibly due to the fact that the management results of aged and serious grade patients in PCS-Japan 94 were better than in ICSTAS. As for the causes of unfavorable results, the direct effect of SAH increased (21%)) and vasospasm showed a tendency to decrease (12.4%) compared with ICSTAS.
