The authors report a study on the rebleeding of cerebral aneurysm in the acute stage, especially during angiography after the first bleeding.
Nine (4.4%) of 204 patients with ruptured aneurysm who were admitted to our hospitals within 6 hours after the first bleeding showed rebleeding during angiography. The incidences of the bleeding were 6 (8.2%) of 73 patients when the angiography was performed within 6 hours after the first bleeding and 3 (9.7%) of 31 patients during next 6 hours. This difference was not significant. In the non-angiography group, the incidence of the rebleeding within 6 hours after the first bleeding was 18.2% (16 out of 88 patients), which was higher than that in the angiography group.
These findings indicate that the angiographic procedure does not lead to a high risk in the acute stage and angiography should be done as early as possible in the patients with ruptured aneurysm in order to perform early operation.
