The Intraoperative magnetic resonance imaging (MRI) machine at Klink Hirslanden has been specially developed for neurosurgery. Coupled to a computer-assisted navigation system it enables an MRI scan to be done at any point during an operation. This is particularly helpful when operating on certain types of brain tumor – allowing to precisely delineate the margin between tumor and healthy tissue. Current research suggests that using this technique can improve the outcome for patients. In cases of malignant brain tumors, particularly glioblastomas, we use intraoperative MRI in combination with a fluorescent dye (Gliolan) in order to further optimize the likelihood of a maximal resection. When operating on pituitary tumors, intraoperative MRI offers a valuable adjunct to endoscope-assisted microsurgery, particularly in order to visualize hidden or difficult-to-access parts of the tumor and assist in its definitive and total removal.
The intraoperative computed tomography (CT) machine at Klink Hirslanden is integrated with the “BrainSuite” system – a neurosurgical operating room equipped with the most up-to-date spatial navigation technology, microsurgical instruments and anesthesiology equipment. At any point during an operation we can perform a CT scan – this is particularly useful in the area of the skull base, for certain brain tumors and for vascular neurosurgery in order to gain precise spatial orientation. Using CT intraopertively in this way, the precision and thus the safety of an operation can be significantly improved. In operations for spine stabilization, intraoperative CT provides exact confirmation of the position of prosthetic discs or screws which may be implanted.
Our intraoperative angiography system allows us to perform the most advanced vascular neurosurgery for aneurysms and arteriovenous fistulae or malformations. Every angiographically-assisted operation is performed by an experienced, interdisciplary team of neuroradiologists and neurosurgeons. Using angeographic monitoring, it is possible to measure particular flow parameters in the blood vessels during the operation, facilitating and optimising intraoperative decision-making.
