With a series of 31 transluminal stent-graft procedures, we assessed the feasibility and clinical effectiveness of a new stent-graft for the treatment of infrarenal abdominal aortic aneurysms (AAAs).
We treated the patients (male; mean age 71 years) with straight or bifurcated nitinol stents covered with woven dacron graft material for infrarenal eccentric saccular AAA (n = 4) or AAA involving the bifurcation and the common iliac arteries (n = 27). The 18-F delivery system was advanced via a surgical arteriotomy and the stent-graft was placed under fluoroscopic control. Follow-up period ranged from 8 days to 9 months.
The implantation of the stent-grafts was technically successful in 30/31 cases. Procedure-related complications were acute hepatic failure due to gastric bleeding in a patient with liver cirrhosis, graft occlusion due to emboli originating from the left atrium (n = 1), macro-embolisation (n = 3), local haematoma (n = 1) and av-fistula (n = 1) requiring surgery. A post-implantation syndrome with leukocytosis and elevated C-reactive protein was observed in all patients.
Endoluminal repair of infrarenal AAA with use of dacron covered nitinol stent-grafts is feasible, safe and clinically effective. However, careful long-term evaluation is necessary.
通过31例腔内支架移植物手术系列，我们评估了一种新型支架移植物治疗肾下腹主动脉瘤（AAA）的可行性和临床疗效。
我们使用覆盖有编织涤纶移植物材料的直型或分叉型镍钛诺支架治疗患者（男性；平均年龄71岁），用于治疗肾下偏心囊状AAA（n = 4）或累及分叉和髂总动脉的AAA（n = 27）。通过手术动脉切开术推进18F输送系统，并在荧光透视控制下放置支架移植物。随访期为8天至9个月。
31例中有30例支架移植物植入技术成功。与手术相关的并发症包括1例肝硬化患者因胃出血导致的急性肝衰竭、1例因左心房栓子引起的移植物闭塞、3例大栓塞、1例局部血肿和1例需要手术治疗的动静脉瘘。所有患者均观察到植入后综合征，伴有白细胞增多和C反应蛋白升高。
使用涤纶覆盖的镍钛诺支架移植物对肾下AAA进行腔内修复是可行、安全且临床有效的。然而，需要进行仔细的长期评估。
