Listen up, folks, we’ve got something huge to talk about here.
We’ve been looking at kids, okay? Kids with these tricky brain issues called arteriovenous malformations, AVMs. And let me tell you, we’ve been doing something incredible with them. We’re talking about repeat stereotactic radiosurgery, SRS. It’s a big deal, and we’ve been doing it for a long time, from 1987 to 2022. Big study.
Now, the main thing we wanted to see was a fantastic outcome. That means we get rid of the AVM without any bad stuff happening, like bleeding or getting worse. And we looked at other things too, like bleeding chances, weird changes because of the radiation, and if any cysts or tumors popped up.
We had 83 kids in this study. They were about 11 years old when they got their first SRS and 15 at the second. A lot of them, 68.7%, only had SRS to manage their AVMs. And half had bleeding before SRS. We saw some differences in the size of the AVMs between the first and second SRS, but the treatment dose was pretty much the same.
After 5 years from the second SRS, half of the kids had their AVMs completely gone. That’s right, half. And the chances of a good outcome got better over time, reaching 44% at 5 years. The risk of bleeding after the second SRS was low, only 8% over 5 years. And those radiation changes? Not a big deal. Only 6% had symptoms. Cysts showed up in 7.2% of the kids, but it took a while, about 47 months.
So, what does this tell us? It tells us that repeat SRS is a winner for kids with AVMs that didn’t go away the first time. The risks are low, and the success is high. We’re going to keep looking into this, but let me tell you, it’s looking good.
Remember, we’re doing something great here for these kids. And we’re going to keep doing it until we get it perfect. That’s what we do, folks. We make things better, and we’re doing it big time with repeat SRS for pediatric AVMs.
