ABSTRACT
PURPOSE:
To evaluate the mid-term results of endovascular repair of abdominal aortic aneurysms and to predict subsequent sac shrinkage.METHODS:
From December 2006 to April 2010, 114 abdominal aortic aneurysms were treated with stent grafts. The intraoperative sac pressure was measured by a microcatheter. Correlations between the diameter change and relevant factors were determined by a logistic regression analysis.RESULTS:
Stent grafts were deployed successfully in all patients. Type-2 endoleaks were noted in 25 patients (22%); there were no type-1 or type-3 endoleaks at discharge. The clinical success rate was 99%. The diameter was reduced in 40 patients (56%) but remained unchanged in 32 (44%). There were no aneurysms that increased in diameter. At 2 years after the repair the rate of cumulative survival was 87% and freedom from secondary intervention was 95%. The sac pressure index after stent grafting with a reduced diameter was 0.56 ± 0.11 and that of patients with an unchanged diameter was 0.52 ± 0.14. There were no significant differences between the two groups. Persistent type-2 endoleaks had a slightly negative effect on sac shrinkage (P = 0.052).CONCLUSIONS:
The mid-term results of endovascular aneurysm repair were satisfactory. Although it was difficult to predict the fate of a sac after stent grafting, persistent type-2 endoleaks were observed to have a slightly negative impact on sac shrinkage.
