裸支架在孤立性内脏动脉夹层治疗中的应用

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。

Application of bare stents in isolated visceral artery dissection

Objective: To evaluate the safety and efficacy of bare stent placement for the isolated visceral artery dissection. Methods: Within May 2008 to March 2012, 6 patients with visceral artery dissection underwent endovascular treatment with bare stents. Of the patients, 5 cases were superior mesenteric artery dissection (SMAD) and one case was celiac artery dissection. The intimal tears and dissecting aneurysms were covered and occluded with single or overlapping double bare stent placement, respectively. Results: All of the 6 patients underwent successful operation without any complications. In the patient with celiac artery dissection and one SMAD patient, the false lumen diminished immediately after overlapping double bare stent placement. In the other 4 patients, the true lumens remained patent and false lumens became occluded as revealed by CT or color Doppler examination 3 months after single or overlapping double bare stent placement. Conclusion: Endovascular management with single or overlapping double bare stent placement is a feasible, safe and effective approach for the visceral artery dissection.
