目的:探讨裸支架在内脏动脉夹层治疗中的安全性及疗效。方法:2008年4月—2012年3月,6例内脏动脉夹层患者接受裸支架腔内治疗。其中,肠系膜上动脉夹层5例,腹腔干动脉夹层1例,分别采用单层或双层裸支架叠加技术隔绝夹层破口及瘤体。结果:6例手术均顺利,无并发症发生,腹腔干动脉夹层患者与1例肠系膜上动脉夹层患者植入双层裸支架后假腔即刻不显影,另4例植入单层或双层裸支架3个月后CT或彩超复查提示假腔闭塞、真腔通畅。结论:采用单层裸支架或双层裸支架叠加技术,是治疗内脏动脉夹层可行、有效、安全的方法。 Objective: To investigate the safety and efficacy of bare stent in the treatment of visceral artery dissection. METHODS: From April 2008 to March 2012, 6 patients with visceral artery dissection received endovascular stent-graft treatment. Among them, 5 cases of superior mesenteric artery dissection and 1 case of celiac artery dissection were used to separate dissection and tumor by single-layer or double-layer bare stent superposition. Results: Six cases of operation were smooth and no complication occurred. The patients with celiac artery dissection and one case of superior mesenteric artery dissection were not developed immediately after implantation of double-layer bare stent. The other four cases were implanted with single or double-layer nude Stent 3 months after CT or color Doppler ultrasound examination prompted occlusion, true cavity patency. Conclusion: The single-layer bare stent or double-layer bare stent superimposed technique is a feasible, effective and safe method for the treatment of visceral artery dissection.
