Safety and Efficacy of Selective Intra-Arterial Cooling Infusion Combined With EVT in Acute Ischemic Stroke

Safety and Efficacy of Selective Intra-Arterial Cooling Infusion Combined With Endovascular Thrombectomy in Acute Ischemic Stroke: A Multicenter, Randomized Controlled, Subject- and Assessor-Blind Clinical Trials

Sponsor

Beijing Shijitan Hospital, Capital Medical University

Enrollment

258 participants

Start Date

Jul 3, 2024

Study Type

INTERVENTIONAL

Conditions

Hypothermia Acute Ischemic Stroke

Summary

This is a multicenter, randomized, controlled, subject- and assessor-blinded clinical trial. The research objective is to evaluate the safety and efficacy of selective intra-arterial cooling infusion combined with endovascular therapy in the treatment of acute anterior circulation large vessel occlusion stroke. This trial aims to enroll 258 subjects. Patients assigned to the control group will receive best medical management (BMM) and endovascular therapy (EVT). Those in the selective intra-arterial cooling infusion group (IA-SCI group) will undergo selective intra-arterial cold saline infusion, in addition to BMM and EVT. Subjects will be interviewed face-to-face at randomization, 24±6 hours, 48±6 hours after randomization, 7±2 days/discharge. Telephone interviews/ face-to face interviews will be performed at 30±3 days and 90±7 days after randomization. The primary outcome is the distribution of Modified Rankin Score at 90±7days after randomization.

Interventions

PROCEDURESelective Intra-arterial Cooling Infusion (IA-SCI)

Pre-recanalization: During the procedure, the micro-catheter is advanced over a micro-guide wire, traveling up through the neck until it reaches beyond the clot. A 50 mL cold 0.9% saline (4 ℃) is infused intro into the ischemic territory at a rate of 10 mL/min via the micro-catheter. This enables the cold solution to infuse into the ischemic territory prior to revascularization. Post-recanalization: After recanalization, cold 0.9% saline (4 ℃) is reinfused into the vessel via the catheter at a rate of 22 mL/min for 10 min, repeated twice with a 10-minute interval between infusions.
