Burr Hole Ultrasound Study

Evaluation of the Feasibility of Measuring Chronic Subdural Hematoma Thickness Via Trans-burrhole Ultrasound

Chronic subdural hematoma (CSDH) is commonly managed through burr hole evacuation. This study evaluates the feasibility of trans burr hole sonography as an alternative postoperative imaging modality.

A pilot study on 20 patients who underwent burr hole surgery for CSDH was therefore planned. Postoperative imaging included both CT and sonographic examinations through the burr hole. We assessed the ability to measure residual subdural fluid thickness sonographically compared to CT.

Inclusion Criteria:

• Burr hole surgery due to chronic subdural hematoma
• Routine performance of an computed tomography scan within 3-7 days postoperative
• Ability to give informed consent

Exclusion Criteria:

• Performance of prior craniotomy
• Performance of prior revision surgery
