n Cardiovascular Journal of Africa - The effect of anatomical factors on mortality rates after endovascular aneurysm repair : cardiovascular topics




The objective of this study was to investigate the effect of anatomical characteristics on mortality rates after endovascular aneurysm repair (EVAR).

We investigated 56 EVAR procedures for infrarenal aortic aneurysms performed between January 2010 and December 2013, and the data were supplemented with a prospective review. The patients were divided into two groups according to the diameter of the aneurysm. Group I ( = 30): patients with aneurysm diameters less than 6 cm, group II ( = 26): patients with aneurysm diameters larger than 6 cm. The pre-operative anatomical data of the aneurysms were noted and the groups were compared with regard to postoperative results.
There were no correlations between diameter of aneurysm ( > 0.05), aneurysm neck angle ( > 0.05) and mortality rate. The long-term mortality rate was found to be high in patients in whom an endoleak occurred.
We found that aneurysm diameter did not have an effect on postoperative mortality rates. An increased EuroSCORE value and the development of endoleaks had an effect on long-term mortality rates.
