The waterjet technique enables precise tissue dissection without thermal damage and with preservation of vessels in general surgery. In neurosurgery, these qualities could help to avoid damage of intact @entity75 in @entity5 resections. The present study reports our first results with this technique in brain @entity3 . Ten @entity1 with intracranial @entity3 underwent surgery with the aid of the waterjet. Resection was performed in combination with conventional neurosurgical methods. The follow-up consisted of neurological examination and MRI studies. Intraoperatively, the device was easy to handle. No complications due to the device were observed. Vessels were preserved at pressures below 20 bars. Six of the @entity5 consisted of soft tissue which was poorly demarcated from the surrounding brain. In these @entity5 , the waterjet was very helpful. It enabled @entity5 debulking by aspiration and - more important - precise @entity5 and @entity75 . The remaining four cases were rather hard and well demarcated @entity3 . In these only separation of the @entity5 from the surrounding brain was achieved. In conclusion, the waterjet can be applied in surgery of brain @entity3 without complications. The device appears particularly suitable for soft, poorly demarcated @entity3 . Further clinical studies with this device are required.
