Neuroendoscopy-assisted Drainage Versus Burr Hole Drainage for Chronic Subdural Hematoma

Condition(s) studied

Investigational drug(s) / intervention(s)

Endoscope-assisted hematoma drainage: The procedure of endoscope-assisted hematoma drainage is performed under local anesthesia with sedation or general anesthesia. During the operation, a single burr hole is drilled at the midpoint of the thickest layer of the hematoma cavity as shown on CT scan. A bone flap measuring 2.0 cm × 2.0 cm is then created using a milling cutter. Under the guidance of a visualized neuroendoscope, the hematoma is thoroughly irrigated and evacuated. A subdural drainage tube is inserted, and postoperatively, continuous subdural drainage of the hematoma is maintained until the drainage ceases naturally or the drainage tube is removed at a maximum of 48 hours postoperatively to terminate the drainage.

Burr hole hematoma drainage: The procedure of burr hole drainage is performed under local anesthesia with sedation or general anesthesia. During the operation, a single burr hole is drilled at the midpoint of the thickest layer of the hematoma cavity as indicated by CT scan. A subdural drainage tube is then inserted. The hematoma cavity is irrigated intraoperatively until the drainage fluid becomes clear. Postoperatively, continuous subdural drainage of the hematoma is maintained until the drainage ceases naturally or the drainage tube is removed at a maximum of 48 hours postoperatively to terminate the drainage.

Study summary

Chronic subdural hematoma (CSDH) is a frequent condition in neurosurgery, leading to fluid accumulation between the meninges, brain compression, neurological dysfunction, and potentially herniation. The efficacy of treatments and their long-term outcomes remain uncertain, with no established standard. Notably, neuroendoscopy-assisted hematoma evacuation, in contrast to burr-hole drainage, enables direct visualization and thorough removal of the hematoma, thereby minimizing residue, lowering recurrence rates, and shortening drainage duration. This study will undertake a multicenter trial to compare these two methods and determine the superior treatment approach for CSDH.

Eligibility

Primary outcome measure(s)

• Recurrence rate within 3 months after operation — From operation up to 3 months postoperatively
  To compare the difference in recurrence rate at 3 months postoperatively between the two groups.
