Introduction:

The endovascular management for diseases of the aorta has increased as an option for patients of high risk for conventional open surgery. The short-term mortality, disease-free and reoperation results, show favourable outcomes compared to open surgery, but there are no results available in this country for the medium (1-12 months) and long-term (>1 year).

Methods:

A bi-directional cohort study, in which the retrospective segment was conducted on patients subjected to endovascular management with an aortic replacement, and the prospective segment on the follow-up of the patients.

Results:

A total of 194 patients, subjected to endovascular treatment and met the inclusion criteria, were identified between April 2002 and December 2015. The follow-up was completed in 82.2% of cases. There were 92 (56.8%) cases of abdominal aorta with a mean follow-up of 4.9 years (95% range; 2.5-8.9). The calculated survival was 92% at one year, 86% at 2 years, and 66.4% at 5 years. The period free of disease was 88.7% at one year, 86.4% at 2 years, and 78.5% at 10 years, with 13 patients requiring re-operation.

There were 67 cases of thoracic aorta, with a mean follow-up of 5.3 years (95% range; 2.9-10.2). The calculated survival was 94% at one year, 90.7% at 2 years, and 75.2% at 5 years. The period free of disease was 88.7% at one year, 86.4% at 2 years, and 78.5% at 10 years, and 9 patients required re-operation.

Conclusions:

The results obtained are favourable and are encouraging to continue offering the endovascular approach since the re-operation survival is similar to that reported in the literature.
