A 62-year-old man with a traumatic high-flow right carotid-cavernous fistula was treated by transarterial balloon occlusion technique. However, because of the relatively small size of the fistula, the balloon could not enter into the cavernous sinus via the fistula. During the procedure, the shunt flow decreased significantly, and we stopped the procedure. Follow-up angiography performed 14 days after the procedure showed complete occlusion of the fistula with a small residual pseudoaneurysm. One year later, the pseudoaneurysm had decreased in size. Repeated transient decrease and stagnancy of blood flow at the fistula during the balloon procedure may have played an important role in the thrombosis in this patient.
一名62岁患有创伤性高流量右颈内动脉海绵窦瘘的男性患者接受了经动脉球囊闭塞技术治疗。然而,由于瘘口相对较小,球囊无法经瘘口进入海绵窦。手术过程中,分流流量显著降低,我们终止了手术。术后14天进行的随访血管造影显示瘘口完全闭塞,伴有一个小的残余假性动脉瘤。一年后,假性动脉瘤尺寸减小。球囊手术过程中瘘口处血流反复短暂减少和停滞可能在该患者的血栓形成中起了重要作用。
