Overcoming refractory subgaleal hematoma with endovascular treatment: A novel therapeutic approach.

Subgaleal hematoma (SGH) is a rare condition in adults, typically resulting from trauma. It has primarily been treated with traditional methods, such as aspiration and needle puncture. However, Conventional treatments, such as simple compression dressings and needle aspiration, have been found inadequate in addressing refractory SGH. To overcome these challenges, we performed endovascular treatment (EVT), involving selective coil embolization of the vessels feeding the hematoma, followed by percutaneous hematoma aspiration and compression dressing. In this case report, a 37-year-old female patient with head trauma developed a recurrent subgaleal hematoma despite conservative treatments. Endovascular treatment was performed, resulting in significant improvement and no recurrence. This case suggests that EVT provides a viable and effective treatment alternative for adult patients with refractory SGH, offering a less invasive approach compared to surgical incision and drainage, with promising long-term outcomes.
