Abstract: Objective To investigate the clinical significance of channel technique combined with stent embolization in the individualized treatment of rupsed wide-necked posterior communicating artery (PCoA) aneurysm with embryonal posterior communicating artery (fPCA).Methods From January 2015 to December 2020,a total of 8 cases of ruptured wide-neck PCoA aneurysms with fPCA were treated in our department.The clinical data of the patients were retrospectively analyzed by using channel technique combined with stent embolization.Results The stent covered the aneurysm neck completely and the aneurysm was completely embolized in 8 patients.There were no postoperative complications such as cerebral infarction.A total of 7 patients were followed up,and imaging results showed that 6 patients were grade I,with smooth PCoA,and no tumor parent artery occlusion or stent displacement was found.Prognosis score showed that 6 patients had good prognosis.Conclusion For ruptured wide-necked PCoA aneurysms with fPCA,the use of channel technique combined with stent embolization is complete,and the PCoA is patency after operation,which is worthy of further clinical use.

摘要： 目的 探讨通道技术联合支架栓塞在合并胚胎型后交通动脉(fPCA)的破裂宽颈后交通动脉(PCoA)动脉瘤个体化治疗中的临床意义。方法 2015年1月至 2020年12月,我科共8例合并fPCA的破裂宽颈PCoA动脉瘤,采用通道技术联合支架栓塞,对患者的临床资料进行回顾性分析。结果 8例患者支架均完全覆盖瘤颈,动脉瘤完全栓塞。术后均无脑梗塞等并发症。共随访到7例患者,影像学随访结果,6例为I级,PCoA畅通,未发现载瘤动脉闭塞、支架移位。预后评分显示6例预后良好。结论 对于合并fPCA的破裂宽颈PCoA动脉瘤,使用通道技术联合支架栓塞,动脉瘤栓塞完全,而且术后PCoA通畅,值得进一步临床使用。
