This clinical trial aims to learn whether blood pressure (BP) guided by individualized cerebral autoregulation (CA) is safe and provides a better prognosis than a fixed target in patients with ischemic stroke after endovascular therapy. The BP of participants will be managed at least 48 hours after revascularization. Researchers will compare the CA-guided BP group with the fixed target BP group to mainly see if individualized BP could help more patients to have their neurological function improved at seven days.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| CA-guided BP | Experimental | The upper and lower limits of autoregulation determined by ICM+ software are used to guide the range of blood pressure control, but no more than 40% above or below the usual BP. From when the upper or lower limit of autoregulation appeared in ICM+ software to 48h after revascularization, the total time of actual BP beyond the CA range will be no more than two hours through drug intervention. |
|
| Fixed target BP | Active Comparator | After randomization to 48h after endovascular therapy, the target of BP was determined by clinicians according to current guidelines, i.e. <180/105mmHg. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Hypotensive Drugs and/or Vasoactive Drugs | Drug | To manipulate the blood pressure within a certain range with hypotensive drugs (e.g. nifedipine, benidipine, captopril, benazepril, irbesartan, labetalol, urapidil) and/or vasoactive drugs (noradrenaline or dopamine). |
| Measure | Description | Time Frame |
|---|---|---|
| Early neurological recovery | the NIHSS score decreased by ≥ 4 from the preoperative baseline | Seven days after endovascular therapy (or on the discharge if less than seven days) |
| Measure | Description | Time Frame |
|---|---|---|
| The proportion of functional independence with modified Rankin Scale scores 0-2 | The Modified Rankin Scale (mRS) is a disability scale with possible scores ranging from 0 (no residual symptoms) to 6 (dead). | 90 days after endovascular therapy |
| Distribution of modified Rankin Scale scores ranging from 0-6 |
| Measure | Description | Time Frame |
|---|---|---|
| (Safety outcome) Symptomatic hemorrhagic transformation | Hemorrhagic transformation graded PH-2 (ECASS) with an increase of NIHSS score ≥ 4 compared to baseline | Within 48 hours after endovascular therapy (or on the discharge if less than 48 hr) |
| (Safety outcome) All-cause death |
