腔内隔绝术治疗腹主动脉瘤(附2例报告)

目的：探讨腔内隔绝术治疗腹主动脉瘤（AAA）的方法、疗效、并发症及存在的问题。方法：2例高龄、多病并存的AAA患者在全订及动脉造影的监控下，植入血管内支架－聚酯移植物复合体，对AAA进行腔内隔绝术。结果：术后定期复查彩超、CT及血管造影显示支架通畅，无移位、扭曲、支架外壁与瘤腔间充满血栓，未发现搏动的肠系膜下动脉及腰动脉，未发现渗漏。AAA外径无变化。患者腹部搏动性肿块消失。结论：腔内隔绝术治疗AAA避免了外科手术的各种缺点，具有简便、安全、疗效确定等优点。

Endovascular exclusion of abdominal aortic aneurysm (report of 2 cases)

Objective: To study the technique, curative effects, complications and problems of endovascular exclusion of abdominal aortic aneurysmC AAA). Methods:Under general anesthesia and dynamic monitor of DSA,endovascular exclusion with a stent-polyester graft complex was successfully performed on two elder patients. Results:Two patients were followed up after operation by color Doppler,CT and DSA. The stent-graft was demonstrated patent.no migration and no torsion was observed. The primary AAA sac was full of thrombi,and no pulsatile lumbar and inferior mesenteric arteries were observed. The external diameter of AAA was unchanged and no leakage was found. The abdominal pulsatile mass disappeared. Conclusion:Endovascular exclusion of AAA is a easy,safe and effective method.
