A 39-year-old woman presented with a right intra-cavernous carotid aneurysm measuring 1.76 cm×1.33 cm. The aneurysm was treated with a self-expandable flow-diverter stent. Follow-up MRI showed normal flow in the internal carotid artery with partial thrombosis of the aneurysmal sac. Two weeks later, the patient developed a right direct carotid-cavernous fistula. The fistula was treated by transvenous route. We concluded that rupture of a previously unruptured aneurysm can occur after treatment with a flow-diverter stent.
一名39岁女性,患有一个大小为1.76 cm×1.33 cm的右侧海绵窦内颈动脉瘤。该动脉瘤采用自膨式血流导向支架进行治疗。随访磁共振成像(MRI)显示颈内动脉血流正常,瘤囊部分血栓形成。两周后,患者出现右侧颈内动脉海绵窦直接瘘。该瘘通过经静脉途径进行治疗。我们得出结论,使用血流导向支架治疗后,先前未破裂的动脉瘤可能会发生破裂。
