OBJECTIVES: Endovascular treatment (ET), in addition to a therapy with intravenous recombinant tissue plasminogen activator IV rt-PA in patients with acute ischemic stroke, has been found to improve outcome. However, data about ET in patients who have not received therapy with rt-PA due to contraindications for IV rt-PA are sparse. Comparison of ET with IV rt-PA versus ET alone in patients with stroke is done using a proximal intracranial arterial occlusion (internal carotid artery, middle cerebral artery (M1-Segment)).
METHODS: During a 5-year period (2011-2016), 236 patients (mean age, 69 ± 14 years; 46% women; median NIHSS score 13 ± 5) who were treated at the Department of Neurology and Neuroradiology at the University of Lübeck, undergoing ET with or without IV rt-PA were included and analyzed.
RESULTS: A total of 144 patients (61%) underwent ET + IV rt-PA, and 92 patients (39%) underwent ET only. The ET with IV rt-PA is associated with a higher rate of favorable functional outcomes (mRS≤2) at discharge from hospital (51.4% vs. 23.1%, p < .001) and lower rate of in-hospital mortality (9% vs. 19.6%, p = .019) and symptomatic intracerebral hemorrhage [sICH] (2.1% vs. 8.7%; p = .019) compared to ET, whereas the modified treatment in cerebral infarction score (mTICI) did not differ between the groups.In the adjusted logistic regression analysis, the ET + IV rt-PA was associated with an increased probability of favorable functional outcome (OR, 4.3; 95% confidence interval [CI], 2.2-8.5; p < .001). For the in-hospital mortality (OR, 0.74; 95% CI, 0.29-1.9; p = .76) and sICH (OR, 0.3; 95% CI, 0.07-1.2; p = .09), no differences were found.
CONCLUSION: Recanalization results after endovascular treatment are not relevantly improved in patients receiving rt-PA. However, an additional therapy with IV rt-PA has a positive impact on functional outcome.
