The HSHS St. Vincent Hospital Neuroscience Center uses leading-edge technology to guide their surgical planning and ensure the highest level of precision when patients need it most. Two of the most commonly used neuroscience technologies are the Stealth Computer Navigation system and the O-arm Surgical Imaging System.
Stealth computer navigation
Stealth Computer Navigation is a navigation system that provides the surgeon information, via CT and MRI scans taken prior to surgery, to guide surgical planning and the approach they will use for surgery. These scans are uploaded to a computer and allow the surgeon to pinpoint the exact location of the issue. It is like a GPS system of sorts, in that the surgeon can see a 3D image of the patient’s anatomy before and during the procedure, while also seeing the exact location of their surgical instruments via two cameras.
The Stealth system is used in a variety of cranial procedures, including tumor resections, brain biopsies and shunt placements. There are many advantages to using the Stealth system — more precise localization of tumors, more complete resection, shorter surgery times and shorter hospital stays.
O-arm Surgical Imaging System
The O-arm is a surgical imaging system used in spinal and spinal trauma-related surgeries. It provides real-time intraoperative 2D and 3D images of the anatomy. The O-arm is used in conjunction with the Stealth system to provide the surgeon with improved visualization when placing spinal instrumentation. It also allows for the confirmation of surgical accuracy before the patient leaves the operating room. This technology helps to reduce complications and improve patient outcomes during spine surgery.
Stereotactic Radiosurgery (SRS)
Stereotactic Radiosurgery (SRS) is not surgery, but rather a form of radiation therapy used to treat some brain tumors and brain abnormalities (i.e. AVMs- a tangle of expanded blood vessels which can impede normal blood flow in the brain). SRS focuses high-power energy on small areas in the brain. In doing so, the treatment can be very precise and less surrounding healthy tissue gets damaged. Patients will need fewer doses than traditional radiation therapy. SRS may be a good option for patients who are too high risk for surgery whether it be related to age, medical problems, or the location of the brain tumor or abnormality. SRS doesn't remove the actual brain tumor or abnormality; instead, it damages the DNA of the tumor cells so they can no longer reproduce. It causes the blood vessels in AVMs to thicken and eventually close off so they no longer disrupt the normal blood flow. SRS can usually be done on an outpatient basis.
