Expansion-floating Craniotomy for the Treatment of Malignant Cerebral Edema Caused by Acute Ischemic Stroke

Rövid összefoglaló (regiszter, angolul)

This clinical study investigates Expansion-floating Craniotomy (EC), a novel surgical technique for treating life-threatening malignant cerebral edema following large hemispheric infarction (commonly known as massive stroke). Malignant edema causes rapid increases in intracranial pressure, compressing vital brain structures and risking fatal brain herniation, requiring urgent intervention. The current international standard treatment is traditional decompressive craniectomy (DC). DC involves removing a section of the skull to allow brain swelling, effectively reducing pressure and mortality risk. It is strongly recommended (Class I, Level A evidence) in major guidelines. However, DC typically requires a second major surgery (cranioplasty) approximately 3 months later to replace the removed bone flap, involving additional costs and risks like progressive intracranial hemorrhage or subdural hygroma. EC is a newer approach designed to potentially eliminate the need for a second surgery. During EC, surgeons use medical titanium plates to temporarily elevate the bone flap, creating immediate space for brain swelling while keeping the bone flap attached. Once brain swelling subsides (usually within weeks), a minor procedure flattens the titanium plates, allowing the patient's own bone to naturally reposition without requiring cranioplasty. EC may be performed based on surgeon assessment of brain swelling, guideline considerations, or experience. If EC is deemed unsuitable during surgery, DC will be performed instead. While early research suggests EC achieves decompression similar to DC while preserving the bone flap, its safety and effectiveness compared to the established DC procedure are not yet fully proven. DC is a well-understood, mature technique with known risks and benefits, including the certainty of needing cranioplasty. Conservative management is reserved for patients unfit for surgery but may not prevent neurological deterioration.This study aims to conduct a preliminary assessment of the outcomes of EC versus DC.
