Abstract

OBJECTIVE:

To compare the effects of open and endovascular repair for abdominal aortic aneurysm.

METHODS:

Between January 2009 and January 2011, 84 patients were randomized to endovascular aneurysm repair (EVAR) or open repair. There were 48 patients in EVAR group, 42 cases were male (87.5%), 6 cases were female (12.5%), aged from 50 to 83 years with a mean of 70.8 years. There were 36 patients in open repair group, 31 cases were male (86.1%), 5 cases were female (13.9%), aged from 50 to 80 years with a meal of 67.4 years. The results of perioperative period and follow-up were analyzed.

RESULTS:

Between the two groups, there was significant difference on operative time (t = 9.863, P = 0.000), blood loss (t = 4.647, P = 0.000), blood transfusion (t = 3.334, P = 0.002), hospital stay (t = 2.327, P = 0.022), and medical expense (t = 2.314, P = 0.023). There was no significant difference for perioperative complications (χ(2) = 0.480, P = 0.488). There was no significant difference for complications (χ(2) = 0.664, P = 0.415) and mortality (P = 0.429) during 3 months follow-up. There was no significant difference for complications during 6 months follow-up (χ(2) = 0.128, P = 0.720).

CONCLUSIONS:

Operative time, blood loss and transfusion, hospital stay in EVAR group are less than which in open repair group, the medical expense of EVAR was higher than open repair. There is no significant difference for complications during 6 months follow-up between 2 groups. Long-term follow-up and more patents are needed to analyze survival rate and long-term complications.
