To analyze the clinical outcome of 26 cases of complex abdominal aortic aneurysm treated with interventional technique combined with endovascular repair.

The clinical data of 56 patients with complex abdominal aortic aneurysm from April 2015 to June 2017 were analyzed retrospectively. The patients were divided into open group (N=30 cases, open operation) and intracavitary group (n=26 cases, endovascular repair+ interventional technique) . SPSS 23.0 software were used to analyze the data, which were in accordance with the normal distribution, and were expressed as (±s), and examined by using independent t test ; the total incidence were examined by using χ² test. Kaplan Meier method were used for survival analysis. A P value of< 0.05 was considered as statistically significant difference.

Compared with the laparotomy group, the intracavitary group had a shorter operative time, less intraoperative bleeding and intraoperative blood transfusion, while ICU observative time, postoperative abrosia time, and hospitalization time were shorter (P<0.05). The total incidence of complications in the intracavitary group was lower than that in the laparotomy group (15.4% vs. 33.3%)(P<0.05). The 3-year postoperative survival rate in the intracavitary group was higher than that in the laparotomy group (80.8% vs. 63.3%), however with no statistically significant difference (P>0.05).

Interventional technology combined with endovascular repair surgery of complex abdominal aortic aneurysms could reduce surgical trauma, shorten postoperative recovery time, and reduce the risk of complications, which is worthy of clinical promotion.
