The optimal strategy for blood pressure management after thrombectomy remains unknown. The primary objective of The Early Intensive Blood Pressure Management after Endovascular Thrombectomy (IDENTIFY) study is to explore the efficacy and safety of early intensive blood pressure management strategies after thrombectomy compared with that of standard management. ⋯ The IDENTIFY study is a prospective, randomized, open-label, assessor-blinded multicenter clinical trial. Patients with acute anterior circulation ischaemic stroke who underwent endovascular thrombectomy within 6 h of stroke onset, achieved successful recanalization, and had two consecutive blood pressure readings > 130 mm Hg during the first 6 h after thrombectomy will be enrolled and centrally randomized into intensive or standard management groups in a 1:1 ratio. Continuous blood pressure monitoring will be initiated at the end of thrombectomy, and patients with high blood pressure during the transfer to the wards will also be enrolled. For patients in the intensive management group, the target blood pressure will be < 130 mm Hg, and the use of antihypertensive drugs will be discontinued if systolic blood pressure goes below 110 mm Hg. The target blood pressure for the standard management group will be < 180 mm Hg, and if systolic blood pressure decreases below 140 mm Hg, the use of antihypertensive drugs will be stepwise decreased until the systolic blood pressure reaches 140 mm Hg again or the infusion is discontinued. Patients will have their blood pressure reduced to the target range within 1 h from randomization and maintained until 24 h after thrombectomy with intravenous hypertensive drugs. A sample size of 600 was predicted. The primary outcome will be the rate of dependency (modified Rankin Scale scores 3-6) at 90 days. Secondary outcomes will include intracerebral hemorrhage (either symptomatic or asymptomatic) within 24 h and 7 days, malignant brain oedema, all-cause death, death and severe disability at 90 days, and quality of life at 90 days, which will be measured using the EuroQol-5 Dimensions-5 Level (EQ-5D-5L) and the 36-Item Short Form Health Survey (SF-36). Safety outcomes will include stroke recurrence within 24 h, early neurological deterioration, hypotension within 24 h, death within 7 days after endovascular thrombectomy, and all-cause acute kidney injury.

The presence of traumatic intraventricular hemorrhage (tIVH) following traumatic brain injury (TBI) is associated with worse neurological outcome. The mechanisms by which patients with tIVH have worse outcome are not fully understood and research is ongoing, but foundational studies that explore prognostic factors within tIVH populations are also lacking. This study aimed to further identify and characterize demographic and clinical variables within a subset of patients with TBI and tIVH that may be implicated in tIVH outcome. ⋯ This study represents one of the largest investigations into prognostic factors for patients with tIVH and demonstrates that admission hemoglobin level and hypotension are associated with outcomes in this patient population. These findings add value to established prognostic scales, could inform future predictive modeling studies, and may provide potential direction in early medical management of patients with tIVH.

Factors associated with discharge disposition and mortality following aneurysmal subarachnoid hemorrhage (aSAH) are not well-characterized. We used a national all-payer database to identify factors associated with home discharge and in-hospital mortality. ⋯ We demonstrate independent associations with hospital characteristics, patient characteristics, and treatment characteristics as related to discharge disposition and in-hospital mortality following aSAH, adjusted for disease severity.
