Recurrent aneurysmal hemorrhage is closely linked with percent of aneurysm occlusion

摘要

The investigators analyzed data on 1,001 patients from the Cerebral Aneurysm Rerupture After Treatment (CARAT) study, which was designed to compare rerupture rates after a subarachnoid hemorrhage (SAH) that was treated initially with coil embolization or surgical clipping. The study was conducted at nine US hospitals and included adults who were discharged in the period 1996-1998 with a primary diagnosis of SAH. Information about the patient, index aneurysm (defined as any aneurysm that was considered to be a possible source of the initial SAH and that was treated during the initial procedure) and procedure undertaken was obtained from medical records.
