Long term control of ventricular fluid pressure by means of a ventricular catheter offers the advantage of pressure-controlled external fluid drainage, especially in patients with space-occupying processes which lead to acute disturbances of the fluid circulation. In a measuring system with the possibility of drainage it is advisable to measure the VFP with a microcatheter. The microcatheter is introduced through the drainage catheter. Both catheters are placed in the anterior part of a lateral ventricle. Communication between the drainage system and the transducer is avoided. There is no necessity for frequent disinfection or changing of parts of the system during long term control of the patient. Any occlusion of the drainage system can be recognized immediately because the measuring procedure will not be interrupted by such an occlusion. In 201 patients the ventricular fluid pressure was recorded by the microcatheter method for a total of 1086 days. The infection rate was under 1%. With simultaneous external fluid drainage it rose to 2.2%. For patients with space--occupying processes of the posterior cranial fossa external drainage is recommended for 5--10 days postoperatively as a precaution against rises in CSF pressure.
通过心室导管对心室液压力进行长期控制具有压力控制下的外部液体引流的优势，特别是对于那些因占位性病变导致液体循环急性紊乱的患者。在一个具备引流功能的测量系统中，使用微导管测量心室液压力是可取的。微导管通过引流导管插入。两根导管均置于侧脑室前部。避免了引流系统与换能器之间的连通。在对患者进行长期监测期间，无需频繁消毒或更换系统部件。由于测量过程不会因引流系统的堵塞而中断，因此可以立即识别出引流系统的任何堵塞情况。在201例患者中，采用微导管法记录心室液压力共计1086天。感染率低于1%。同时进行外部液体引流时，感染率升至2.2%。对于后颅窝占位性病变的患者，建议术后进行5 - 10天的外部引流，以防脑脊液压力升高。
