New Possibilities in Vision for Neurosurgery

Infrared 800 is an efficient technique that delivers critical information quickly and conveniently to the surgeon without procedural disruption, optimizing the overall operating workflow. This fluorescence option enables better recognition of blood flow, and is specially tailored to the requirements of vascular neurosurgery both for the treatment of vascular diseases, such as cerebral aneurysms or arteriovenous malformations (AVMs), and for bypass operations. For these procedures, vessel blood flow must be monitored before and confirmed after surgery to ensure the surgical progress.

Blue 400 facilitates precise definition of tumor margins during fluorescence-based malignant brain tumor resection and the removal of tissue. In the treatment of malignant brain tumors, the primary difficulty lies in distinguishing between tumor margins and healthy tissue under standard surgical conditions. During the removal of the malignant tumor tissue, vital and functional areas of the brain must be preserved to ensure that the patient's quality of life is not impaired. Blue 400 serves as an excellent aid for visualizing tumors clearly and precisely at any time during the procedure. The malignant tissue glows red in the Blue 400 mode, allowing the surgeon to recognize and treat the tumor margins more effectively.

"The opportunity to have an angiogram that is so easy and allows you to manipulate the vessels or the aneurysm, while you are performing it, is incredibly exciting to neurosurgeons,” said Robert F. Spetzler, M.D., chairman and medical director of the Barrow Neurological Institute (Phoenix, AZ, USA).

Blue 400 and Infrared 800, developed by Carl Zeiss Meditec (Oberkochen, Germany), have been integrated into a single system in the Zeiss output module interface (OPMI) Pentero surgical microscope, designed for use in neurosurgery, ear nose and throat (ENT) surgery, and spine surgery.
