目的评价腔内人造血管内支撑术治疗腹主动脉瘤的早期临床疗效。方法自1998年2月至1999年2月，根据6例腹主动脉瘤患者三维重建螺旋CT和动脉造影结果，于术前对每个腹主动脉瘤近远端的瘤颈长度、直径和角度，以及动脉瘤和骼总动脉、馆外动脉本身的直径等主要参数进行测量，动脉瘤直径为4．6～8．0cm，平均6．3cm；肾动脉下腹主动脉直径为1．8～2．2cm，平均2．0cm；近端瘤颈长度为2．5～3．5cm，平均3．0cm。6例均采用经腹股沟切口腹主动脉瘤腔内人造血管内支撑术。4例选用Vanguard分叉型腔内人造血管，2例选用Vanguard直型腔内人造血管。结果6例患者术后即刻DSA造影显示动脉瘤消失，近远端人造血管与宿主动脉结合处均未见渗漏。5例患者术后生命体征平稳，1例因手术时间过长、术中反复造影，导致术后急性肾功能衰竭和多脏器功能衰竭，于术后第3天死亡。5例患者术后1周行螺旋CT扫描随访，2例术后3个月、1例术后12个月分别行螺旋CT扫描和彩色超声显像随访，显示人造血管无移位，无渗漏，动脉瘤腔无增大。结论近期随访表明，腔内人造血管内支撑术是一种创伤小、安全有效、恢复快的治疗腹主动脉瘤的新方法，但远期疗效还有待继续随访。
Objective To evaluate the early clinical efficacy of endovascular prosthesis for abdominal aortic aneurysm. Methods From February 1998 to February 1999, based on the results of three-dimensional reconstruction of spiral CT and angiography in 6 patients with abdominal aortic aneurysm, the length, diameter and angle , As well as the main parameters of the aneurysm and the common iliac artery, the diameter of the extracorporeal artery itself, the diameter of the aneurysm was 4.6 ~ 8.0cm with an average of 6.3cm; the diameter of the inferior abdominal aorta of the renal artery was 1.8 ~ 2 .2cm, an average of 2.0cm; proximal neck length of 2.5 ~ 3.5cm, an average of 3.0cm. 6 cases were treated by transvaginal incision abdominal aortic aneurysm endovascular graft. 4 cases selected Vanguard bifurcated intracavitary artificial blood vessels, 2 cases selected Vanguard straight intracavitary artificial blood vessels. Results Six patients underwent immediate DSA angiography showed disappearance of the aneurysm and no leakage of proximal and distal artificial vessels to the host artery. Five patients had stable postoperative vital signs. One patient had prolonged operation time and repeated intraoperative angiography, leading to postoperative acute renal failure and multiple organ failure, and died on the third postoperative day. Five patients were followed up by spiral CT scan one week after operation. Two patients were followed up for 3 months and one after operation for 12 months. Spiral CT scan and color ultrasound imaging were performed respectively. No displacement and leakage were observed in the artificial blood vessels , Aneurysm cavity without enlargement. Conclusion Recent follow-up shows that endovascular graft is a new method to treat abdominal aortic aneurysm with small trauma, safe and effective, and fast recovery. However, the long-term curative effect remains to be followed up.
