From Steven D. Chang, MD, on Brain Tumors and Cerebrovascular Disease · · Stanford Health Care
“Image-guided navigation is like a GPS satellite for your brain. It helps the neurosurgeon who's operating on your tumor know precisely where to make the opening into the bone and really helps guide us through the brain tissue to get to the tumor.”
On , Steven Chang, President of Quantitative Systems Pharmacology at SIMULATIONS PLUS INC, spoke about image-guided surgery during Steven D. Chang, MD, on Brain Tumors and Cerebrovascular Disease on Stanford Health Care.
In a 2009 interview for Stanford Medical Minutes, Steven D. Chang, MD, then a professor of neurosurgery and co-director of the Stanford CyberKnife program, discussed the treatment of brain tumors and cerebrovascular conditions. He described advances such as image-guided navigation and electrophysiologic monitoring, and explained the CyberKnife as a frameless, outpatient radiosurgery system that delivers highly focused radiation in a single session. Chang noted that treatment decisions for benign brain tumors depend on factors like size, symptoms, and patient age, with large tumors often requiring conventional microsurgery and smaller ones suitable for radiosurgery. Chang also addressed malignant gliomas, stating they are managed with a multimodality approach combining surgery, radiation, and chemotherapy. He discussed arteriovenous malformations (AVMs) as abnormal blood vessels at risk of hemorrhage, with treatment options including surgery, radiosurgery, and embolization. For aneurysms, he described surgical clipping and endovascular coiling as available options, and for trigeminal neuralgia, he noted that medications often fail, leading to surgical interventions such as microsurgery or CyberKnife radiosurgery.
