Summary
This trial will test if inhaling nitric oxide can help treat stroke caused by a blood clot in an artery.
Who is the study for?
This trial is for adults aged 18-79 who've had a recent ischemic stroke and are undergoing mechanical thrombectomy. They should have had mild to moderate disability before the stroke, show significant symptoms, and be within 16 hours of symptom onset. Patients with severe kidney issues, allergies to contrast media, extreme blood sugar levels or certain other health conditions are excluded.
What is being tested?
The study tests the safety and effectiveness of inhaled nitric oxide (iNO) in patients having a procedure called intra-arterial mechanical thrombectomy to remove blood clots caused by an acute ischemic stroke. Participants must require general anesthesia during this procedure.
What are the potential side effects?
While specific side effects of iNO in this context aren't detailed here, generally iNO can cause headaches, low blood pressure, methemoglobinemia (a condition where oxygen delivery is affected), or airway inflammation.

Eligibility Criteria:
This trial includes the following eligibility criteria:- I have had a stroke that wasn't caused by bleeding and my condition is serious.You have had a CT scan of your head without contrast, and the ASPECT score is 6 or lower.I am not in a vulnerable group such as being mentally ill, a prisoner, terminally ill, pregnant, or a child.I have a blockage in my brain or neck arteries.My stroke symptoms started less than 16 hours before my clot removal procedure.I received IV tPA treatment more than 4.5 hours after my symptoms started.I do not have severe blood clotting issues or use certain blood thinners with poor kidney function.You have any bleeding or abnormal growth in your head.I will be under general anesthesia for my throat surgery.You have a blockage in the main artery of the front part of your brain, as shown by a special type of x-ray called a CT Angiogram.The CT scan shows that the size of the damaged area in the brain is less than 70ml, and the ratio of the area at risk to the damaged area is 1.8 or higher, with at least 15ml of at-risk tissue.My blood pressure is either very low (<100/60) or very high (>185/110) and hard to control.My stroke is thought to be caused by an infection in my blood.I need a machine to help me breathe and will be asleep during my treatment due to the severity of my stroke.You are allergic to the dye used for imaging tests.My kidney function is severely reduced.I was mostly independent before my stroke.Your blood sugar levels are either too low (less than 50mg/dL) or too high (more than 400mg/dL).Your hemoglobin level is less than 7 mmol/L.I am between 18 and 79 years old.I had a seizure when my stroke started, making it hard to assess my condition.I have not had a severe head injury in the last 3 months.
