Conference paper


Since the early 1970s, we have been advocating ultra-early surgery for ruptured cerebral aneurysms, and have reported on its therapeutic effectiveness [8, 11]. In 1985, however, Nishimoto, et al. reported [4] that the surgical results in ruptured cerebral aneurysm cases from various neurosurgical clinics in Japan were quite poor when the operation was performed within 48 h of onset. Even for relatively mild grades I and II cases, the mortality was said to be 26.6%, and it was notably poor for more severe cases: 35.6% in grade III, 55.2% in grade IV, and 79.1% in grade V cases. We are consequently concerned that such results using early stage surgery can only have caused a complete loss of confidence in this procedure in the West.
