Cerebral angiographies were performed within 3 hours after the rupture in the 96 cases of cerebral aneurysm during the last 4 years. The 5 cases out of these 96 cases showed the rerupture of aneurysm. The 4 cases out of these 5 cases were died and the remained one case was saved from death by the emergency operation. However, the extravasation of contrast material was observed in the all cases. In addition, the site of rerupture observed in the 5 cases was found to be located at the internal carotid artery, especially closely to the injection site, suggesting that the pressure of direct hand-injection rather than the catheter-injection through the femoral artery. Therefore, it is recommended that, in the case of the emergency angiography by the autoinjector set using less sensory incentive contrast material; metrizamide, should be used.
