Thromboemboli and thromboembolisms

Video transcript

I want to clarify some of the terminology I used in the last video but before I do that let's just make sure that we understand the mechanism of how arteries can get blocked so in the last video we talked about these plaques forming and if this plaque is unstable at some point it could rupture and when it ruptures this material can start to flow out into the bloodstream it can start to float into the bloodstream and two things will happen I just want to make it a little bit more clear relative to the last video especially now that I can zoom in on these arteries two things can happen Plex or I should say clotting not plaques these are the plaques that have been released the clotting the clotting factors can kind of clot these released these released pieces from the plaque and the other thing that can and often will happen and I didn't talk about this in depth in the last video is that you can also have when this thing ruptures you can also have blood clots blood clots form here let me do this in a red more reddish color so you can also have blood flop clots form on the ruptured plaque so everything even if the the plaque the part of the plaque that has not begun to move can can experience clotting and also the part of the plaque that's kind of been dumped into the blood stream can also clot and the last video we saw that one of these clots can go downstream to some point where the arteries get narrow enough so that they actually block the artery so that they actually block the artery right over here and that just restricts the blood flow so now all of a sudden you don't have any blood flow going downstream and all of this muscle tissue that needs the blood flow from this point that needs to get oxygen from that it might die and you might have a myocardial infarction or a heart attack now what I want to clarify is the actual terminology I somewhat and it was a little bit I guess I was a little bit hand-wavy with the terminology we only get a little bit deeper here this actual clot that forms that can restrict the blood vessel this is a this right here is a thrombus this right here is a thrombus thrombosis the process of a thrombus forming so thrombosis is are these blood clots that form that can actually help to kind of obstruct obstruct a blood vessel so this thrombus right here is actually going to make it harder for the blood to flow through it's going to make it harder for the blood to flow through this vessel now any of these released pieces or chunks in any of these blood vessels that can float around and eventually lodge themselves in and eventually block block the blood flow these are called emboli or if I if I just use them in the singular one of these is an embolus is an embolus and I want to be clear an embolus is the general term for anything that can float around in your blood and eventually lodge itself at some point in in in your in your circulatory system and restrict the blood flow what we drew in the last video and in particular this one as well is that these emboli that have that are also clotted so they're also kind of thrombus that they're also thrombi and emboli at the same time these this right here would be called a thromboembolic thromboembolic thrombo embolus embolus these words are strange to say sometimes so it wouldn't be wrong to call it an embolus but in particular we say it's a thromboembolic soon oh that it's kind of this clotted material around this released plaque that can go Lodge itself and the last video I call this a thrombosis but that was really not quite right the thrombosis is really the formation of the clot that can restrict the blood flow when it actually lodges itself further when it actually breaks off becomes an embolus and lodges itself further off and restricts restricts blood flow this is called a thromboembolism thromboembolism let me write this the Rhambo embolism so hopefully I'm not confusing you too much at these medical terms confuse me a lot but I want to make it very clear that our most this is just the general formation of a blood clot inside of a blood vessel that can restrict the flow of blood so this right here this this is thrombosis occurring that is thrombosis thrombosis once things break off and they start floating around there an ambulance that's the general term for it and in particular if it's if it's broken off material that is due to a clot it's a thrombo ambulance so thrombo ambulances are a more specific way of calling it an embolus and once one of these things lodge themselves and block and block the blood flow that's a thrombo embolism you could also call that an embolism just when you say it's thromboembolism it makes it a little bit more specific to know that it's kind of clotted material so hopefully that doesn't that clarifies things and doesn't confuse you too much
