BACKGROUND: It is unclear what factors providers take into account to determine the target blood pressure (BP) after mechanical thrombectomy (MT) in patients who had acute ischemic stroke. We aimed to understand practice patterns of post-MT BP management across institutions in the United States.

METHODS: We surveyed StrokeNet institutions providing MT and post-MT care with an online questionnaire, designed to understand institutional post-MT BP management practices.

RESULTS: Of 131 potential institutions, 58 completed the survey. The majority of institutions target systolic BP (SBP, n = 53, 91%) during the first 24 hours post-MT (n = 32, 55%) using nicardipine as a first-line agent (n = 43, 74%). At most institutions, BP management is determined by a team of physicians in a collaborative fashion (n = 30, 52%) and individualized on a case-by-case basis (n = 39, 67%) after taking the reperfusion status into account (n = 42, 72%). In patients with successful reperfusion, 36% (n = 21) of the institutions target SBP in the range of 120-139 mm Hg, 21% (n = 12) target 140-159 mm Hg, and 28% (n = 16) would accept any value less than or equal to 180 mm Hg. In patients with unsuccessful reperfusion, 43% (n = 25) would accept any SBP value less than or equal to 180 mm Hg and 10% (n = 6) would target SBP less than or equal to 220 mm Hg.

CONCLUSIONS: We found that majority of the institutions do not have a standardized protocol for post-MT BP management. There was interinstitutional heterogeneity in the preferred target of SBP post-MT and most institutions target values of SBP lower than 180 mm Hg in post-MT patients. Prospective data and randomized control trial are needed to identify the optimal target BP.
