Background:

We depict the experience with the use of thrombolysis for acute ischemic stroke in a tertiary center in South America.

Objective:

To describe the main outcomes in our population of patients aged less and older than 80 years treated with recombinant tissue plasminogen activator.

Materials and Methods:

Retrospective observational study. We described the main variables and the difference in outcome accounting for age.

Results:

70 patients were included. 51.4% of the patients were women, 22.8% were older than 80 years. The average window time was 70 minutes and the average door-to-needle time was 90 minutes. Hypertension, dyslipidemia and previous stroke were the most common risk factors. Favorable outcome Modified Rankin Scale ≤2 was present in 25% of the patients older than 80 years and 53.7% in the population younger than 80 years (p=0.009). Mortality was present in 31.2% of the patients older than 80 years and in 5.5% of the patients younger than 80 years (p=0.005). Symptomatic intra-cerebral hemorrhage was found in 6.25% of the patients older than 80 years (p=0.65), compared to 3.7% in the younger than 80 years.

Conclusions:

We found that intravenous thrombolysis still had benefit in people older than 80 years. Significant differences in symptomatic intra-cerebral hemorrhage were not found, however, a greater mortality in patients older than 80 years was. These findings of our experience of recombinant tissue plasminogen activator use in real life are consistent with other latinamerican publications. MÉD.UIS. 2017;30(3):21-30.
