Willis环周围窄颈动脉瘤与栓塞材料选择的相关性

背景：随着影像学设备与栓塞材料的不断发展,颅内动脉瘤的血管内栓塞治疗也成为治疗方法之一。目的：探讨Willis环周围窄颈动脉瘤的形态学特点与栓塞材料选择及血管内栓塞治疗的关系。方法：用双源CT血管成像检查筛选患者,采用Seldinger技术行全脑血管造影,根据动脉瘤的不同解剖学形态选用合适的弹簧圈进行介入栓塞治疗。结果与结论：31例患者共36枚动脉瘤均成功栓塞,完全栓塞31枚、占86.11%,大部分栓塞5枚、占13.89%;随访6～12个月,所有患者均未发生再出血或脑血栓形成;动脉瘤的栓塞程度不仅与动脉瘤的形态有关,而且与栓塞材料直接相关。故认为根据不同的形态学特点选用合适的弹簧圈进行血管内栓塞治疗,是一种安全有效的方法。

Correlation between narrow carotid artery aneurysm around Willis ring and selection of embolic materials

BACKGROUND：With the continuous development of the imaging equipments and embolic materials,intracranial aneurysm endovascular embolization has become a treatment method.OBJECTIVE：To investigate the relationship of the morphological features of narrow carotid artery aneurysm around the Willis ring with the embolic material selection and endovascular embolization treatment.METHODS：Dual-source CT angiography screening examination was performed in patients undergoing Seldinger technique of cerebral angiography with digital signature algorithm,according to the different anatomical forms of aneurysm,the appropriate choice of coil was conducted for embolization.RESULTS AND CONCLUSION：Thirty-one patients with 36 aneurysms were successfully embolized,complete thrombosis in 31,accounting for 86.11%,the majority of embolization in 5,accounting for 13.89%.After a follow-up of 6 to 12 months,all patients did not present with re-bleeding or thrombosis.Aneurysm embolization was not only related to the aneurysm shape,but also related to embolic materials.Therefore,to choose appropriate endovascular coil according to the morphological characteristics is a safe and effective method.
