Abstract
OBJECTIVE: A sono catheter for transendoscopic imaging was applied in neurosurgery for the first time in 52 patients with a broad variety of lesions. METHODS: A transendoscopic sono catheter (Aloka Deutschland GmbH, Düsseldorf, Germany) with a diameter of 1.9 mm (6F) was used and introduced into the working canal of an endoscope. The image produced by the probe is a 360 degrees scan ("brain radar") displayed on a monitor, on which some parameters can be varied to get the best view of the different anatomical structures. RESULTS: In 39 patients intraoperative imaging was the main reason for investigation and in 13 patients neuronavigation was the focus of interest. In 18 cases of tumor resection control targeting a visualized remnant was necessary. There are limitations and artifacts, which should reveal themselves in laboratory and clinical experience. CONCLUSION: In this small series, endo-neuro-sonography proved to make neuroendoscopy safer and easier by online and real-time imaging with high resolution.
