摘要

<b><i>Objective:</i></b> This study aimed to control blood pressure (BP) under transcranial Doppler (TCD) guidance in patients with anterior circulation acute ischemic stroke after endovascular treatment (EVT) to reduce the incidence of early neurological deterioration (END) and improve neurological prognosis. <b><i>Methods:</i></b> This prospective randomized controlled study included 95 patients who were randomly divided into a TCD-guided BP control (TBC) group and a non-TCD-guided BP control (NBC) group. The patients were monitored by TCD within 72 h after EVT. In the TBC group, BP decreased, BP increased, or intracranial pressure decreased when TCD showed blood flow acceleration, deceleration, or intracranial hypertension respectively. The BP of the NBC group was controlled according to the guidelines. The incidence of END and the prognosis was compared between the 2 groups. <b><i>Results:</i></b> TCD identified 18 patients with blood flow acceleration, but the prognosis of the 2 groups was not significantly different. TCD identified 23 patients with blood flow deceleration, and the poor prognosis rate at discharge was lower in the TBC group than in the NBC group (45.5 vs. 91.7%, <i>p</i> = 0.027). TCD identified 34 patients with intracranial hypertension, and the 3-month mortality rate of the TBC group was lower than that of the NBC group (0 vs. 36.8%, <i>p</i> = 0.011). The incidence rates of END and 3-month mortality in the TBC group were lower than those in the NBC group (13.8 vs. 37.5%, <i>p</i> = 0.036; 0 vs. 25.0%, <i>p</i> = 0.012) when TCD parameters were abnormal. Multivariable logistic regression analysis showed that the TBC group (adjusted OR 0.267, 95% CI 0.074–0.955; <i>p</i> = 0.042) was an independent protective factor against the incidence of END when TCD parameters were abnormal. <b><i>Conclusion:</i></b> These findings indicated that TCD-guided BP and intracranial pressure control improved the prognosis of patients with blood flow deceleration and intracranial hypertension.
