We report our initial experience with the modular AneuRx Stent Graft System for the treatment of infrarenal abdominal aortic aneurysm (AAA) in National Taiwan University Hospital. From July 2002 to October 2003, 5 patients were recruited for stent graft repair. Patients were all male, and aged from 62 to 82 years. The stent grafts were deployed via the opened femoral arteries under fluoroscopic guidance. Endograft deployment was successful in all 5 patients. The average procedure time was 139 +/- 23 min, and mean blood loss was 310 +/- 167 mL. All patients had a smooth postoperative course. Type II endoleak was noted in 3 patients initially, which sealed spontaneously in 2 of them. One patient developed graft limb thrombosis 1 month after operation, which was treated by femoral-femoral bypass. Treatment was successful in all patients with no mortality during 1-year postoperative follow-up.
