Cuff therapy could boost brain recovery after hemorrhage
NCT ID NCT06032533
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a simple, non-invasive treatment called remote ischemic conditioning (RIC) for people who have had a brain bleed from a burst aneurysm. The treatment involves briefly inflating a blood pressure cuff on a limb to improve blood flow and reduce brain damage. Researchers will compare recovery and independence at 6 months between 100 participants who receive real RIC versus a sham (fake) treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Aneurysmal subarachnoid hemorrhage confirmed by computed tomography (CT) with aneurysm origin confirmed by computed tomography angiography (CTA) or digital subtraction angiography (DSA) * Aneurysmal subarachnoid hemorrhage symptom-onset ≤ 3 days * Aneurysm protected by clipping or coiling * Independent in daily living before symptom onset (mRS ≤ 2) Exclusion Criteria: * Subarachnoid hemorrhage caused by a lesion other than cerebral aneurysm * Symptomatic vasospasm at the time of enrollment * Previous cerebral lesion e.g. symptomatic cerebral infarction (\>2cm), multiple sclerosis, symptomatic intracerebral hemorrhage, tumour, prior neurosurgery (excluding prior clipping or coiling of cold aneurysms without complications). * History of severe peripheral vascular disease or signs of severe peripheral vascular disease on physical examination * History of deep vein thrombosis or signs of deep vein thrombosis on physical examination * Kidney involvement or prior kidney disease with an estimated glomerular filtration rate (eGFR) below safe levels for contrast infusion in relation to CT-perfusion. * Pregnancy (Women of child-bearing age will have serum-Humane Choriogonadotropine taken prior to final inclusion. If pregnancy cannot be ruled out,the patient can't be included. Women with a safe birth control method will be encouraged to use this method during the entire period of active treatment.) * Concomitant other acute life-threatening medical or surgical condition
