Stereotactic Radiosurgery for Residents-Radiosurgery for Arteriovenous Malformations

Video Transcription

Video Summary

The video discusses the natural history of arteriovenous malformations (AVMs) and their management through different treatment approaches, including microsurgery, radiosurgery, and endovascular treatment. The risk of hemorrhage from an AVM is about 3% per year, with previous hemorrhage increasing the risk. The video mentions different grading systems used to assess the size and location of AVMs, as well as the goals of AVM management, which include eliminating the risk of future hemorrhage, preserving neurological function, and minimizing treatment-related risks. Radiosurgery is shown to have a high rate of obliteration and can be used for small and deep-seated AVMs. The video also discusses a trial called the ARUBA trial, which compared medical treatment with surgical interventions for unruptured AVMs. The trial was stopped early due to a higher rate of adverse events in the treatment arm. However, the short follow-up period of the trial is criticized, and the results are still being studied. The video concludes by discussing outcomes and complications of radiosurgery for AVMs, as well as the use of embolization and other treatment approaches for large AVMs.
