Abstract：
Intracranial pressure (ICP) measurements are imperative for the proper diagnosis and treatment of several neurological disorders. Telemetric sensors have shown their utility for ICP estimation in short-term monitoring in humans. However, their long-term reliability is uncertain. The authors present the case of a 37-year-old woman diagnosed with benign intracranial hypertension and obesity. The patient underwent gastric bypass surgery for ICP control. In order to monitor ICP before and after bariatric surgery, a Neurovent-P-tel sensor was implanted in the left frontal lobe. After gastric bypass, normal ICP values were recorded, and the patient\'s visual fields improved. However, the patient experienced incapacitating daily headaches. The authors decided to implant a Codman Microsensor ICP transducer in the right frontal lobe to assess the long-term reliability of the Neurovent-P-tel measurements. A comparison of the recordings at 24 and 48 hours showed good correlation and reliability during long-term monitoring with the Neurovent-P-tel, with minimal zero drift after 11 months of implantation.
摘要：
颅内压（ICP）测量对于正确诊断和治疗几种神经系统疾病至关重要。遥测传感器已显示出其在人体短期监测中用于ICP估计的实用性。然而,他们的长期可靠性是不确定的。作者介绍了一名37岁的女性，被诊断患有良性颅内高压和肥胖症。患者接受了胃旁路手术以控制ICP。为了监测减肥手术前后的ICP，在左额叶植入了Neurovent-P-tel传感器.胃旁路手术后,记录正常ICP值,和病人的视野改善。然而,患者每天都出现头痛。作者决定在右额叶植入Codman微传感器ICP换能器，以评估Neurovent-P-tel测量的长期可靠性。24小时和48小时的记录比较显示，在使用Neurovent-P-tel进行长期监测期间，具有良好的相关性和可靠性。植入11个月后具有最小的零漂移。
