Oh, brace yourselves for a thrilling tale of cerebral arteriovenous malformation, a condition that’s as fun to say as it is to treat. In a groundbreaking display of digital prowess, researchers have decided to play a high-tech game of “what if” with patients’ blood vessels using CT Angiographic imaging and the ever-so-user-friendly Mimics software. Because, why not turn a serious medical condition into a virtual Lego project?

With the precision of a teenager on a gaming marathon, they’ve simulated the blood flow in these twisty vessels using both Newtonian and non-Newtonian models, because apparently, blood can’t decide if it’s a fluid or a ketchup. And, of course, they’ve used COMSOL Multiphysics, the CFD equivalent of a Swiss Army knife, to solve those pesky Navier-Stokes equations that have been keeping us all up at night.

But wait, there’s more! They’ve validated their virtual bloodbath with real data (because using fake data would be just silly), ensuring that their simulated occlusions are as accurate as a horoscope. And lo and behold, they’ve discovered that clogging up these vessels increases blood pressure. Who would’ve thought that blocking blood flow could have such an effect?

In a shocking twist, it turns out that blood behaves differently in smaller vessels, suggesting that maybe, just maybe, we should consider this when simulating. So, in a stroke of genius, they’ve concluded that non-Newtonian simulations are the way to go for those pesky little vessels. Because if you’re going to simulate, you might as well simulate with style.

In summary, if you’re into virtual blood flow blockage and have a thing for computational fluid dynamics, this research is like a summer blockbuster for the cerebrally inclined. Just remember, it’s all fun and games until someone’s blood pressure actually goes up.
