<br/><br/> CONCLUSIONS: Our study demonstrates that wide BP excursions from the mean during the first 24hours post MT are associated with worse outcomes in patients with nrLVO.

METHODS: Hourly systolic BP (SBP) and diastolic BP (DBP) values were prospectively recorded for 24hours following MT in consecutive nrLVO patients. Maximum, minimum, and mean BP levels were documented. Three-month functional independence (FI) was defined as modified Rankin Scale (mRS) scores of 0-2.  OBJECTIVE: Permissive hypertension may benefit patients with non-recanalized large vessel occlusion (nrLVO) post mechanical thrombectomy (MT) by maintaining brain perfusion. Data evaluating the impact of post-MT blood pressure (BP) levels on outcomes in nrLVO patients are scarce. We investigated the association of the post-MT BP course with safety and efficacy outcomes in nrLVO.  RESULTS: A total of 88 nrLVO patients were evaluated post MT. Patients with FI had lower maximum SBP (160+/-19mmHg vs 179+/-23mmHg; P=0.001) and higher minimum SBP levels (119+/-12mmHg vs 108+/-25mmHg; P=0.008). Maximum SBP (183+/-20mmHg vs 169+/-23mmHg; P=0.008) and DBP levels (105+/-20mmHg vs 89+/-18mmHg; P=0.001) were higher in patients who died at 3 months while minimum SBP values were lower (102+/-28mmHg vs 115+/-16mmHg; P=0.007). On multivariable analyses, both maximum SBP (OR per 10mmHg increase: 0.55, 95%CI 0.39 to 0.79; P=0.001) and minimum SBP (OR per 10mmHg increase: 1.64, 95%CI 1.04 to 2.60; P=0.033) levels were independently associated with the odds of FI. Maximum DBP (OR per 10mmHg increase: 1.61; 95%CI 1.10 to 2.36; P=0.014) and minimum SBP (OR per 10mmHg increase: 0.65, 95%CI 0.47 to 0.90; P=0.009) values were independent predictors of 3-month mortality.
