Endoscopic evacuation of chronic subdural hematoma with rigid and flexible endoscope: case report.

INTRODUCTION: Subdural haematoma (SDH) is a common neurosurgical condition after head trauma requiring evacuation to prevent secondary brain injury. The first choice of management in these patients is a large craniotomy or burr-hole evacuation. However, sometimes due to lack vision during drain tube insertion or irrigation the authors might land up in a complication like cortical bridging vein rupture, haemorrhage etc. Also, the management of septate chronic SDH (CSDH) with multiple neo-membranes does not have a well-defined surgical approach. Recently, endoscopic evacuation has been reported to a be a feasible method for evacuation in acute, subacute and chronic SDH patients.

PRESENTATION OF CASE: A 65-years-old male patient presented with a history of recent head injury and symptoms of headache and urinary incontinence of 7 days (Glasgow Coma Scale Score 15/15). Computed tomography scan revealed CSDH at both fronto-parietal convexity more on right side.

DISCUSSION: The authors reported our initial experience on a typical case of an older patient with chronic subdural haematoma and its evacuation with the assistance of both rigid and flexible endoscope. The authors could visualize cortical bridging veins and neo-membranes intraoperatively and guided our drainage tube accordingly to avoid inadvertent haemorrhage. There was no recurrence of symptoms postoperatively. Thus we achieved apparent successful evacuation of the CSDH in this patient in a 6-month follow-up.

CONCLUSION: Endoscopic evacuation of CSDH proves to be an effective minimally invasive modality and more studies are required on larger patient groups with long-term follow-up imaging to confirm its superiority.
