A long term follow-up study on the nonsurgical therapy of abdominal aortic aneurysm in senile patients / 解放军医学杂志

ABSTRACT

Objective To study the course of development of aneurysm of abdominal aorta (AAA) with nonsurgical treatment in senile patients. Methods 37 subjects were included in the study, and they were divided into 3 groups according to the size of aneurysm observed at the first visit. The diameter of aneurysm was measured, and the measurement was repeated at periodic follow up. The yearly increase of the diameter was calculated and analyzed. Results For the 37 patients, the AAA mean diameter was 4.68cm at the first visit. The period of follow-up was 0.5 to 11 years, with a mean of 6.1 years. The average yearly increase in tumor diameter was 0.47cm/year. 14 patients with aneurysm diameter of 6.0cm had an average increase of 0.67cm/year. 5 patients died during the follow-up period, 2 of them died of rupture of the aneurysm, the diameter of which was 8.35cm and 8.91cm, respectively. Endoaneurysmorrhaphy with stent was performed in 7 patients. Conclusion The size of AAA in the senile patients increased slowly if the aneurysm diameter is 6.0 cm, the tumor size might increase quickly, and active intervention is recommended.
