Abstract：
BACKGROUND: In intraventricular surgery using a flexible endoscope, the lesion is usually aspirated via the working channel. However, the surgical view during aspiration is extremely poor because the objective lens is located adjacent to the working channel.
METHODS: To address this issue, we developed a novel surgical procedure using an angiographic catheter. In this procedure, the catheter is inserted into the working channel, and the lesion is aspirated through the catheter. Besides, continuous intraventricular irrigation is performed via the gap between the catheter and the working channel.
CONCLUSIONS: This procedure maintains a clear view during surgery and reduces complications.

摘要：
背景：在使用柔性内窥镜的脑室内手术中，病变通常通过工作通道抽吸。然而,因为物镜位于工作通道附近,所以在抽吸期间的手术视野极差。
方法：要解决此问题，我们开发了一种使用血管造影导管的新型外科手术.在这个过程中，将导管插入工作通道,并通过导管抽吸病变。此外,连续脑室内冲洗是通过导管和工作通道之间的间隙进行的。
结论：该程序在手术过程中保持了清晰的视野，减少了并发症。
