主动脉弓型覆膜支架的设计与实验观察

Treatment of aortic arch aneurysm with graftstent by endovascular surgery

目的 研究和探讨主动脉弓瘤的腔内微创治疗。方法 10头小型猪首先被制作成主动脉弓瘤的动物模型 ,用自制主动脉弓型覆膜支架在DSA电视屏幕监视下 ,将输送器送入主动脉弓瘤体部位定位后释放 ,通过血管造影确定覆膜支架释放情况。结果 10头动物模型中除 2头因麻醉意外死亡 ,其余均获成功。血管造影提示瘤体影象消失 ,主动脉弓发出各分枝显影良好 ,支架周围无漏血现象。

Objective To study the feasibility of treatment of aortic arch aneurysm with graftstent by intravascular surgery. Methods Animal model of aortic arch aneursym was established using 10 piglets. An aortic arch shaped graftstent was transferred and implanted to the site of aortic arch aneurysm through femoral artery under angiography. Results The aortic arch shaped graftstent was successfully implanted in 8 piglets. Two piglets died from anaesthetic accident. Angiography showed diappearance of aneurysm, splendid development of the branches of aortic arch, and no blood leakage around the stent. Conclusion Treatment of aortic arch aneursym by implantation of graftstent by endovascular surgery is feasible.
