[Comparative analysis of open surgical repair and endovascular aortic repair in the treatment of abdominal aortic aneurysm implicated visceral arteries]

Objective: To evaluate the value of open surgery repair and endovascular aortic repair in the treatment of abdominal aortic aneurysm which implicate visceral arteries. Methods: From January 2012 to October 2016, 26 patients were reviewed. According to the treatment, they were divided into open surgery group (n=7) and endovascular repair group(n=19). Then, the characteristics and relative data of follow-up of the two groups were analysis. Results: In open surgery group, there were 7 patients. All of them were men, median age 58(41-62) years and 1 patient were older than 75 years. And in endovascular repair group, there were 19 patients(14 men) of median age 72(66-76) years, 8 patients were older than 75 years. Patients in endovascular repair group were significantly older than who were in open surgery group (Z=-13.06, P<0.05). Complications of open surgery group and endovascular repair group were 57.14% and 15.79% respectively. There was no statistically significant difference (χ(2)=3.13, P>0.05). During follow-up, the diameters of aneurysm which planted stents were smaller than before. Conclusions: In the treatment of abdominal aortic aneurysm implicated visceral arteries, open surgery is mainly suitable for the patients with low-risk. But the rate of complications was high. By contrast, endovascular aortic repair with small trauma and high safety, has becoming the first choice.
