Abstract: OBJECT Aneurysmal rerupture prior to treatment is a major cause of death and morbidity in aneurysmal subarachnoid hemorrhage. Recognizing risk factors for aneurysmal rebleeding is particularly relevant and might help to identify the aneurysms that benefit from acute treatment. It is uncertain if the size of the aneurysm is related to rebleeding. This meta-analysis was performed to evaluate whether an association could be determined between aneurysm diameter and the rebleeding rate before treatment. Potentially… Show more

“…This, in turn, interferes with the critically stable local anatomic situation after aSAH. Apart from larger aneurysm size, 14 additional risk factors as identified in the past could not be confirmed. 3,11,12 This is probably explained by the methodological design and small sample size of these previous studies.…”

“…4,7 Although studies in the past have already showed that a rebleeding most frequently occurs in the first 24 hours after ictus, [8][9][10] exact rebleeding rates in relation to time after ictus have never been undisputedly established. 3 Moreover, although several risk factors have been linked to an early rebleeding in retrospective analyses of rather small series of patients, [11][12][13][14] firm evidence about risk factors is lacking. In clinical practice, it is therefore still unknown which patients are at an increased risk for a rebleeding and thus require immediate aneurysm repair.…”

“…Of the 297 patients included in our previous study, 30 (10.1%) patients experienced rebleeding; 14 (46.7%) cases occurred within 24 h after ictus, 11 (36.7%) occurred between 1 and 7 days, and 5 (16.6%) occurred after 7 days [5]. High blood pressure, poor-grade clinical condition, modified Fisher grade, posterior circulation aneurysms, larger aneurysms (>10 mm), intracerebral or intraventricular hemorrhage are reported to be important predictors of rebleeding after aSAH [24,[28][29][30]. Van Donkelaar et al [28] reported that a higher modified Fisher grade was a strong risk factor associated with a rebleeding probably because the amount of blood was a marker of stability of the ruptured aneurysm wall.…”

“…26,27 Aneurysmal rerupture prior to treatment is estimated to be approximately 15% during the first 24 hours, with a majority of rebleeds occurring within the first 6 hours after presentation. 26,28 Risk factors associated with pretreatment rebleeding are poor clinical grade at presentation, associated ICH, and increasing size of the aneurysm. 26,27…”
