Short-term recurrence after interventional embolization of intracranial aneurysms: case report and literature review

目的:探讨介入栓塞治疗颅内动脉瘤短期复发的相关因素。方法:分析4例介入栓塞术后短期内复发的颅内动脉瘤患者的诊治过程,并结合文献进行讨论和总结。结果:4例患者均行介入栓塞术治疗颅内动脉瘤,其中1例术后1周复查MRA发现复发,DSA复查证实复发,1例出院2月后再出血,DSA复查证实复发,2例通过6月后首次复查DSA证实复发。4例患者均再次行介入栓塞术致密填塞颅内动脉瘤,出院时复查未见复发。结论:动脉瘤介入栓塞术后短期复发与动脉瘤的填塞率、大小、形状、位置有密切关系。介入术后应进行密切的影像学随访,复发动脉瘤应被再治疗。

Objective： To discuss the relevant factors contributing to short-term recurrence after interventional embolization of intracranial aneurysms. Methods： Four cases of short-term recurrence after interventional embolization of intracranial aneurysms were studied, and their diagnosis were discussed along with literature review. Results： All 4 cases were received the standard treatment of interventional embolization and their recurrence was confirmed. One showed recurrence by MRA in a week during examination, which was confirmed by intracranial DSA; one occurred hemorrhage two months after discharge, which was confirmed by DSA; and the other 2 cases were identified by DSA six-month after discharge.All 4 cases were treated again with high dense embolization and none showed recurrence after discharge. Conclusion： The short-term recurrence after interventional embolization of intracranial aneurysms was closely associated with the rate of embolization,the size,shape,and position of the aneurysms. Close follow-up by image examination is necessary,and recurrence should be treated once diagnosed.
