About this trial

The goal of this clinical trial is to test the combination of hypothermia and endovascular treatment in acute stroke patients with large vessel occlusion.

The main question it aims to answer is: does an additional cooling to 35°C result in a benefit on clinical outcome ? Participants receive immediate cooling using a noninvasive transnasal cooling technique (RhonoChill) and are maintained at 35°C for 6 hours after reopening of the vessel using surface cooling, and then slowly rewarmed.

Researchers will compare the intervention group (hypothermia and endovascular treatment and best medical treatment including iv thrombolysis) and control group (only endovascular treatment and best medical treatment including iv thrombolysis) to see if additional hypothermia leads to a better outcome after 3 months without relevant complications.

Eligibility criteria

Qualifiers

Pre-stroke modified Rankin Scale (mRS) 0-2 [7-point scale rating from 0 (no symptoms) to 6 (dead)]

Acute ischemic stroke with NIHSS >5

Last seen normal to groin puncture < 6h: native CT or MRI-DWI with ASPECTS >5

Last seen normal to groin puncture 6-24h or unknown time window: significant mismatch imaging according to the eligibility criteria of the DEFUSE-3 trial

Disqualifiers

Patients with an intranasal obstruction that prevents complete insertion of the nasal cannula should not be treated with the RhinoChill system.

Known severe hemorrhagic diathesis (International Normalized Ratio (INR) >3.0, partial thromboplastin time (PTT) > 70s, platelet count < 50.000/μl)

Brain trauma or neurovascular surgery/intervention <3 months

Severe infection
