Supplementary Material for: Transcirculation Approach for Matricidal Carotid Cavernous Aneurysm - Not a Good Choice. A Case Report of Unsuccessful Endovascular Treatment of Matricidal Carotid Cavernous Aneurysm.

Matricidal carotid cavernous aneurysms (CCAs) are rare and dangerous condition. The treatment failure of endovascular approach like flow divertion, coiling or stent-coiling is relatively high with considerable morbidity and mortality. Transcirculation approach is an alternative treatment option, but, in case of matricidal CCAs, the results are not well documented in the literature. The authors present a complicated case of an unsuccessful transcirculation approach for matricidal CCA finally treated with sacrifice of parent artery and high-flow bypass.

侵袭性颈内动脉海绵窦段动脉瘤（matricidal carotid cavernous aneurysms, CCAs）是一种罕见且凶险的疾病。血管内治疗（如血流导向疗法、弹簧圈栓塞术或支架辅助弹簧圈栓塞术）的失败率相对较高，且伴随较高的发病率与死亡率。经循环入路是一种可选治疗方案，但针对此类侵袭性CCAs时，相关治疗效果在现有文献中鲜有记载。本文作者报告了一例复杂病例：患者接受经循环入路治疗失败后，最终通过结扎载瘤动脉并行高流量搭桥术完成治疗。
