Posttreatment intracerebral hemorrhage (ICH) after recanalization therapy of acute ischemic stroke increases morbidity and mortality. Dual-energy (DE) computed tomography (CT) allows differentiation of blood-brain barrier disruption (BBBD) and ICH. We evaluated the incidence of ICH and BBBD immediately after endovascular recanalization therapy, the correlation between BBBD and final infarction or ICH size, and the prognostic value of postinterventional BBBD.
