Abstract:
Objective To sum up our preliminary experience for the treatment of abdominal aortic aneurysm ( AAA) using unibody bifurcation stent-graft ( UBST). Methods This study included 42 cases, among them there were 39 AAA cases, one case of abdominal aortic pseudoanrurysm (AAPA) , one case of type C dissecting aortic aneurysm, one descending aortic aneurysm (DAA) with AAA. Five stent-grafts were deployed for the case with DAA and AAA including 4 stent-grafts were used for DAA and one UBST for AAA. For the case of type C dissecting aortic aneurysm, one straight stent-graft was used for sealing the proximal intimal tear, one UBST was deployed for sealing the distal intimal tear. A graft bypass was required in the case with AAPA through extraperitoneal incision occlusion of external iliac artery of one side, then an UBST was deployed for sealing the rupture of abdominal aorta. Results The average operative time was 50 minutes. One patient died. One more proximal cuff was required in 8 cases. One more distal cuff was required in one case, one more proximal and distal cuff respectively were required in one case. Postoperative transient slight leakage was present in 8 cases. Both internal iliac arteries were sealed in 5 cases; unilateral internal iliac artery was sealed in 20 cases. Success was reached in two cases with an angle of 90 degress between aneurismal neck and body. Conclusion The exclusion of AAA using UBST is successful and safe.
