As operative therapy for intracerebral hematoma and craniotomy for hematoma removal, CT guided stereotaxic operation is familiar.
In spite of its effeciency, institutions rarely use ultrasound guidance in operations to remove hematoma.
Advantages of intraoperative ultrasound monitoring are;.
1. Real-time display is available during the operation.
2. Scanning sections are freely selective.
3. Intermittent and/or continuous monitoring is available.
4. The probe is small and does not obstruct the operative field.
5. Precise information can be obtained, which can reduce operation time.
We used ultrasound monitoring for intracerebral acute and chronic hematoma removal operations using a 12 mm diameter 5 MHz probe. For this monitoring, we developed a probe holder in order not to obstruct the FOV under the microscope. We also made a puncture needle guide attachment to do ultrasound monitoring even for microscopic surgery, such as a cerebral tumor operation.
We made a special needle using an eight gauge, silicon puncture needle with two side holes at the tip and 10 mm from the tip and with this equipment proceeded to remove hematoma.
