Abstract:
Objective To retrospectively analyze the geometrical characteristics of abdominal aortic aneurysms undergoing endovascular treatment in a single medical center.The long-term effects as well as the strategies for the prevention and treatment of complications have been reviewed.Methods From January 2003 to December 2010,clinical data and geometrical parameters of 344 cases undergoing endoluminal repair of abdominal aortic aneurysms were analyzed retrospectively.Results The diameter and length of proximal neck was (23 ± 3 )mm and ( 26 ± 12) mm respectively.The angle between the neck and the abdominal aortic aneurysm was (25 ± 28) degree.The surgical success rate was 99.7％.The average follow-up time was 32.9 months (3 -84 months) with follow-up rate 81.8％ (279/341).The mortality was 1.1％ (3/279),the re-intervention rate was 10.4％ (29/279) and the overall complication rate was 12.9％ ( 36/279),including endoleak of 5.7％ ( 16/279 ),stent-graft migration of 1.1％ ( 3/279 ),aneurysm expansion or rupture of 5.4％ ( 15/279 ),and other complications like limb occlusion.Severe infrarenal aortic neck angulation ( ＞ 60 degree) was associated with type Ⅰ endoleak ( P =0.010 ).Conclusions A careful preoperative case selection and evaluation is the key for a successful endovascular aneurysm repair.Endoleak continues to be the major long-term complication of the endoluminal grafting technique,and the major cause for re-intervention.Life-long follow-up is extremely important.
