Outline

Text

Objective: Shunt treated patients frequently present with misleading and complex symptoms. Clinical examination and imaging do often not lead to satisfactory results and consecutive valve adjustments even aggravate the situation. Experiences in the past could clearly demonstrate benefits of telemetric ICP devices for such challenging cases. In this series, a new telemetric device to individually adjust shunt valves according to the current ICP was evaluated.

Methods: Between December 2015 and November 2016, 26 patients underwent implantation of the Sensor Reservoir. An initial ICP measurement to confirm the diagnosis was performed in each case. Thereafter, multiple measurements and valve adjustments under ICP control followed.

Results: Initial telemetric measurements revealed shunt overdrainage in 18, underdrainage in 4, suboptimal valve settings in 3, and normal ICP values in one case. In all 26 patients, a total of 174 measurements and 67 valve adjustments were performed. This corresponds to a rate of 6.7 measurements, respectively 2.6 valve adjustments per patient. These efforts led to a clear clinical improvement in almost 70% of the patients. Complications occurred in 4 patients including wound healing disorder (2/4), shunt infection (1/4), and technical failure of the device (1/4).

Conclusion: The first clinical results are promising. The possibility to simultaneously recognize and resolve shunt related problems is the decisive advantage. However, improvements of the system are necessary.
