支架治疗肠系膜上动脉夹层的临床效果评价

Efficacy of Stent Placement in the Treatment of Superior Mesenteric Artery Dissection

【目的】评价支架治疗肠系膜上动脉夹层的近期临床效果。【方法】回顾中山大学附属第一医院放射介入科2009年1月至2018年12月收治的14例肠系膜上动脉夹层并行支架置入治疗的患者作为研究对象,术中采用裸支架或者覆膜支架置入治疗肠系膜上动脉夹层。主要观察支架置入前后腹痛评分、肠系膜上动脉真腔内径的变化,并分析技术成功率和1年内的支架通畅率。【结果】支架置入技术成功率达100%,术后腹痛症状改善(疼痛评分5.9 vs.1.9,P<0.05),肠系膜上动脉真腔内径较术前有显著改善(6.6 mm vs.2.6 mm,P<0.05)。支架置入后12个月的通畅率为100%。【结论】支架置入治疗肠系膜上动脉夹层可改善腹痛症状及血管真腔内径,近期临床疗效好。

【Objective】Evaluate the efficacy of stent placement in the treatment of superior mesenteric artery dissec⁃tion(SMAD).【Methods】Data of 14 cases with SMAD treated with stent placement in our center between January 2009 and December 2018 were retrospectively analyzed.All lesions were treated with bare stent or covered stent deployment.The numeric rating scales(NRS)and diameter of superior mesenteric artery true lumen before and after the procedure were compared and analyzed.The success rate of technique and the primary patency rate of stent within one year were also analyzed.【Results】The success rate of procedure was 100%technically.There was significant difference in numeric rat⁃ing scales between before and after procedure(5.9 vs.1.9,P<0.05).Diameter of superior mesenteric artery true lumen was significantly improved compared with those before procedure(6.6 mm vs.2.6 mm,P<0.05).The primary patency rates of stents in 12 months were 100%.【Conclusion】Endovascular stent placement is an effective treatment of SMAD with symptoms improved.
