The aim of the present study was to analyze the clinical data on rebleeding in cerebral aneurysms during angiography and to evaluate the importance of the time interval between the latest rupture and angiography. Fourteen personal cases and 202 patients reported in the literature are reviewed. Rebleeding during angiography occurred most often (78%) on Day O; 89% bled when angiography was performed within 6 hours of the latest rupture. The prognosis in such ruptures was poor, with a mortality of 79%. Intentional delay in angiography of at least 6 hours from the latest rupture is recommended if the associated hematoma is not large.
本研究的目的是分析脑血管造影术中脑动脉瘤再出血的临床数据，并评估最近一次破裂与血管造影之间时间间隔的重要性。回顾了14例个人病例以及文献报道的202例患者。血管造影术中再出血最常发生在第0天（78%）；89%的患者在最近一次破裂后6小时内进行血管造影时发生出血。此类破裂的预后较差，死亡率为79%。如果相关血肿不大，建议从最近一次破裂起至少延迟6小时进行血管造影。
