To the Editor I have some concerns about the recent article1 that investigated whether recent exposure to vitamin K antagonists (VKAs) in patients with acute ischemic stroke selected to undergo endovascular thrombectomy (EVT) increased the risk of symptomatic intracranial hemorrhage (sICH).

Arosh S. Perera Molligoda Arachchige (2023) studied this question. Vitamin K antagonist exposure prior to endovascular thrombectomy was the subject of a letter raising concerns about its reported association with symptomatic intracranial hemorrhage.
