Radiosurgery, also known as stereotactic radiosurgery (SRS), is a non-invasive treatment method that utilizes precisely focused radiation beams to address tumors and other conditions affecting the brain and spine. Unlike traditional surgery, no incision is made during radiosurgery. Instead, it employs advanced 3D imaging techniques to deliver high doses of radiation directly to the targeted area, minimizing the impact on surrounding healthy tissues. This article aims to provide an in-depth understanding of radiosurgery, its mechanism of action, different types, conditions treated, potential side effects, and the technology behind it.
Radiosurgery, specifically stereotactic radiosurgery (SRS), involves the use of multiple precisely focused radiation beams to treat tumors and other conditions in the brain and spine. It is a non-invasive procedure that does not require traditional surgical incisions. By utilizing advanced 3D imaging, SRS delivers high doses of radiation to the affected area while minimizing damage to surrounding healthy tissues. In many cases, stereotactic radiosurgery for brain and spine conditions can be completed in a single session, providing convenience and efficiency for patients.
Similar to other forms of radiation therapy, stereotactic radiosurgery works by damaging the DNA of the targeted tumor cells. This damage prevents the cells from reproducing, ultimately causing the tumors to shrink. The high dose of radiation delivered during stereotactic radiosurgery not only induces tumor shrinkage but also leads to the closure of blood vessels over time, effectively cutting off the tumor’s blood supply.
Stereotactic radiosurgery techniques may vary slightly depending on the specific machine used to deliver the treatment. Several radiotherapy machines are employed for SRS treatment, including:
Stereotactic radiosurgery is effective in treating various cancerous and non-cancerous brain and spine conditions, including:
Stereotactic radiosurgery is generally a safe procedure with minimal risks compared to traditional surgery. Since no surgical incisions are involved, complications related to anesthesia, bleeding, and infection are significantly reduced. However, there are some potential side effects to be aware of:
Radiosurgery, particularly stereotactic radiosurgery (SRS), offers a non-invasive and highly precise treatment option for various brain and spine conditions. By leveraging advanced imaging technologies and radiation delivery techniques, SRS delivers high doses of radiation directly to the targeted area, leading to tumor shrinkage and minimal impact on healthy tissues. With different types of SRS machines available, treatment can be tailored to the specific needs of each patient. Although there may be some temporary side effects, the overall risk profile of SRS is lower compared to traditional surgery. Stereotactic radiosurgery continues to revolutionize the field of neurosurgery, providing patients with effective and convenient treatment options.
