[Analysis of the direct costs associated with mechanical thrombectomy and intravenous fibrinolysis in the Hospital Universitario Central de Asturias].

INTRODUCTION: The increase in the indications for mechanical thrombectomy and its implementation in Spanish hospitals makes it necessary to determine the costs related to this treatment so as to be able to streamline economic resources and allow them to be distributed in an appropriate manner. AIMS: To analyse the direct costs associated with patients with acute ischaemic stroke who are treated with intravenous fibrinolysis and with mechanical thrombectomy, and to assess the effectiveness and safety of both treatments during the first 90 days of progression in the Hospital Universitario Central de Asturias. PATIENTS AND METHODS: A retrospective analysis was performed that included 44 patients who received intravenous fibrinolysis and 61 patients treated with mechanical thrombectomy, in whom a series of clinical and economic variables were analysed.
RESULTS: The mean final total cost per patient was 16,059 euros in treatments with thrombectomy and 8,169 euros in those in which intravenous fibrinolysis was administered. The percentage of patients with a good functional prognosis at 90 days was 63.93% in those treated by endovascular means and 56.82% in those who received intravenous fibrinolysis. Mortality rates were 18.03 and 11.36%, respectively.
CONCLUSIONS: The mean cost of treatment with mechanical thrombectomy, as well as the total mean cost per patient during the acute phase of the disease associated with this technique, is higher than in the case of intravenous fibrinolysis. In our setting, both intravenous fibrinolysis and mechanical thrombectomy are considered to be effective and safe.
