【摘要】 目的 对兔颈总动脉侧壁型动脉瘤模型进行改进,以评价建模的成功率及支架植入后颈总动脉的通畅率。方法 取新西兰大白兔20只,饲养1周后行左侧颈内动脉结扎。1个月后行颈部3.0 T MRA检查评价颈动脉与椎动脉的变化情况。采用间断式外翻缝合法吻合静脉囊与颈总动脉,建立侧壁型动脉瘤。在植入覆膜支架前、术后即刻、3个月、6个月行血管造影。结果 20只实验兔均顺利行左侧颈内动脉结扎。MRI示结扎前右颈总动脉中段平均直径为(2.35 ± 0.08)mm,结扎后1个月右颈总动脉中段平均直径为(2.89 ± 0.22)mm ,与术前比较差异有显著统计学意义(P < 0.01)。MRA示17只兔右颈总动脉明显增粗,而双侧椎动脉略增粗;3只兔颈总动脉增粗不明显,而双侧椎动脉明显增粗。建立兔颈总动脉囊状动脉瘤模型17 只,术后均健康成活。DSA示覆膜支架植入前所有动脉瘤及右颈总动脉通畅,4个动脉瘤腔内有少量血栓形成,但无自发性完全闭塞。Willis或镁合金覆膜支架植入术后即刻造影示动脉瘤闭塞,右颈内动脉通畅。术后3个月DSA示16只兔右颈内动脉通畅,1只闭塞。术后6个月DSA示16只兔右颈内动脉通畅。动脉瘤模型的成功率为100%(17/17),覆膜支架植入后右颈总动脉的通畅率为94.1%(16/17)。结论 兔颈总动脉侧壁型动脉瘤模型制作的改进提高了动脉瘤模型的成功率及覆膜支架植入后右颈总动脉的通畅率。
