OBJECTIVE: We studied short-term and long-term effects of covered stent endovascular graft exclusion for the treatment of abdominal aortic aneurysm rupture.

PATIENTS AND METHODS: From January 2013 to January 2016, 88 patients with fractured abdominal aortic aneurysm were enrolled in this study. Patients were divided into the control group or the open abdomen group (n=52) and the observation group or the isolated group (n=36). Patients in the control group were treated with open abdominal aneurysm resection and artificial blood vessel transplant technique, while patients in the observation group were treated with percutaneous stent graft endovascular graft exclusion. The outcome of two methods was compared.

RESULTS: Surgical success rate and the mortality rate after 24 h and 30 days in the observation group were not significantly different than those in the control group (p>0.05). Short-term total mortality and complication rate in the observation group were lower than those in the control group and the differences were statistically significant (p<0.05). Operative time and intraoperative blood loss in the observation group was significantly less than those in the control group and the differences were statistically significant (p<0.05). The comparison of follow-up survival rate, recurrence rate, and secondary surgery rate in two groups showed no statistically significant differences (p>0.05).

CONCLUSIONS: Short-term effects of endovascular graft exclusion for the treatment of abdominal aortic aneurysm rupture was superior to laparotomy, while the long-term effect was similar.
