[Intravenous thrombolysis for ischemic stroke: Experience in 54 patients].

BACKGROUND

Intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) reduces disability in patients with ischemic stroke. However, its implementation in Chilean public general hospitals has been slow and faces some difficulties.

AIM

To analyze the results of an intravenous thrombolysis protocol implementation in a public general hospital.

MATERIAL AND METHODS

During a lapse of 28 months a standardized protocol for intravenous thrombolysis implemented in the emergency room of a public hospital, was prospectively evaluated. Fifty four patients with ischemic stroke were treated and assessed three months later as outpatients.

RESULTS

At three months of follow-up, 66.4% of patients subjected to thrombolysis had a favorable evolution, defined as having 0 to 1 points in the modified Rankin scale. Intracerebral hemorrhage rate was 11.1%, including 5.5% of symptomatic intracerebral hemorrhage. Four percent of patients had systemic bleeding complications after thrombolysis. The mortality rate was 14.8%.

CONCLUSIONS

The success rates, mortality, and complications rate were comparable to the results obtained in international studies, despite of the absence of a stroke unit to manage stroke and its complications.
