Examining changes in the lymphatic drainage system after brain hemorrhage

Radiological Changes of Glymphatic-meningeal Lymphatic Drainage System After Spontaneous Subarachnoid Hemorrhage

Observational Second Affiliated Hospital, School of Medicine, Zhejiang University · NCT06444438

This study is trying to see how a brain bleed affects the drainage system that helps clear waste from the brain in people who have had a subarachnoid hemorrhage.

What this trial studies

This observational study investigates the glymphatic-meningeal lymphatic drainage system in patients who have experienced a subarachnoid hemorrhage (SAH). It aims to understand how the influx of blood components into the cerebrospinal fluid circulation affects this drainage system and its role in complications such as cerebral edema and neuroinflammation. By utilizing advanced imaging techniques, the study seeks to provide clinical evidence of changes in the lymphatic drainage system post-SAH, which has only been previously confirmed in animal models.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 18-80 who have experienced spontaneous subarachnoid hemorrhage and are undergoing aneurysm interventional therapy.

Not a fit: Patients with a history of trauma or prior brain injury, as well as those with significant comorbidities or missing imaging data, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of complications following subarachnoid hemorrhage, potentially enhancing patient outcomes.

How similar studies have performed: While this approach has shown promise in animal studies, clinical evidence in humans is currently lacking, making this a novel investigation.
