ABSTRACT
BACKGROUND:
Antithrombotic therapy (AT) should generally be avoided within 24 hours after recombinant tissue-plasminogen activator (rt-PA) treatment but should be considered in patients with large-artery atherosclerosis (LAA) who undergo concomitant emergent endovascular treatment (EVT). The aim of the present study was to assess the safety of AT within 24 hours after rt-PA treatment in patients with hyperacute ischemic stroke due to LAA who received concomitant EVT.METHODS:
From January 2013 through July 2019, consecutive patients with acute ischemic cerebrovascular disease due to LAA who were admitted within 6 hours from symptom onset were recruited. The patients were classified into six groups based on the reperfusion treatment and early (within 24 hours) AT from rt-PA treatment. Safety outcomes were compared among the groups.RESULTS:
A total of 155 patients (35 women [23%], median age 74 [IQR 66-79] years; NIHSS score 3 [1-10]) were included in the present study. Of these, 73 (47%) received no reperfusion therapy, 24 (15%) received rt-PA treatment and early AT, seven (6%) received rt-PA without early AT, 26 (17%) received EVT only, six (4%) received both rt-PA and EVT without early AT, and 19 (12%) received rt-PA and EVT with early AT. AT was administered a median of 3.9 (1.6-8.0) hours after rt-PA in patients with rt-PA+EVT with early AT. AT within 24 hours after rt-PA and EVT treatment did not increase hemorrhagic complications (p > 0.05 for all).CONCLUSION:
In this retrospective analyses, early AT administration for patients with hyperacute stroke due to LAA treated with rt-PA plus EVT did not increase hemorrhagic events.Palabras clave
