Brain Circulation / Circle of Willis Made Simple! 

Helpful to break down the cerebral circulation. One "correction"...A venous clot from a DVT should not make it to the brain, but would rather go to the Lungs as a Pulmonary Embolism. That is unless you have a PFO in the the heart. Better to describe an embolus from the heart as an example. thanks for breaking things down!

Thank you. You made the complex topic into simple through your video and demonstration. Hats off

Thanks, man. The clinicians are riding our asses out in M4 for not knowing the basics. This was a great review.

Very, very grateful for this video...big help for tomorrow's exam

I liked that video very much. I am 53 years old. I had 2 CVA's in 1969 and now, have epilepsies since. . Very interesting. Thanks.

Thank you so much for this video! I've been searching for an appropriate diagram that shows the circle of willis clearly and your video has been the best so far. :)

Thanks, it's easy to follow, and to the point. And I like how you sometimes show a little (almost childlike) excitement in your voice. It makes it fun and enticing to watch!

Your demonstration and clarification is awesome. Thank you.

TY for this, made understanding brain circulation easier!

This is a great video! Just something to mention maybe in the beginning would be that the vertebral arteries first begin at the subclavian, and also pass through the foramen magnum before reaching the brain. This made everything so simple, thanks so much!

Exactly what I needed, thank you for sharing!

I always love your videos and your teaching style. Thank you so much. Les

Great video, only thing is that a DVT will embolize to the lungs causing a pulmonary embolism. A systemic blood clot (i.e. left sided cardiac origin or arterial origin like the ICA) is the correct illustration for a stroke causing embolization.

watched this before my exam...time spent well.

Thank you, I'm studying for my vascular ultrasound boards this is a awesome help

Thank you for clarifying this topic.

Thank you, this was very useful for tomorrow's class.

Great video. One correction, a DVT won't cause an occlusion of an intracranial artery.

Thank you very much. Very well describe and jn a simplest way.

Thank you so much for making this video. It is very helpful.

Dude, awesome video. Great job breaking it down.

Thank u very much I have an exam and this realy did help A million thanks :-)

Very interesting but hard to remember at first sight)) THank you!

Great Teacher!!

Small clarification, C7 actually does have a transverse foramen, although it does not (generally) convey the vertebral artery.

thanks that really made it more easier

very good, ty.its help me a lot

this is very important!

Thanks for your effort , great video

You are God sent. Thank you very much!

love this video if you work with this and the mnemonic video too, really goo

refreshing my brain, this video helped a lot.

good video ........appreciate the effort....................

Very explicit!

Thanks, this is so easy to follow :)

Thank you, Very useful.

Did you happen to make a video of the pathology that follows when the PCA and MCA/ACA gets blocked? That would be super useful. Thanks for this though.

Thanks! you made this so easy! If you use Visible Body too if you're watching this video you can see how it's in 'real life', because this is such a diagram. Great video!

thanks soomuch

thanks for ur great help sir.

Good one (y)

thank you, this was very useful

well done!thanks a lot..

Good job.....

hi publisher !, thanks for sharing this video it helped me to review. i heard on 15:40 min ''anterior cerebral , posterior cerebral'' should have been cerebellars.regards!

Very helpful video:)

Very useful, but I want to know how it works.....

Yeap, we dont expect Venous Thrombosis to cause arterial thromboembolism...Nevertheless, this is still possible despite being uncommon, there is a phenomenon called 'Paradoxical embolism' where venous thrombosis can cause arterial thomboembolism thru a Patent foramen ovale

Thank you so much!!!

Thank you

Jeremy 25% of autopsy findings demostrate a patent foramen ovale/small atrial septal defect. Therefore paradoxical arterial embolic phenomena is possible. Possible causes include: 1. an eisenmenger type picture whereby the pulmonary hypertension resulting from Pulmonary Embolus will see RAP > LAP resulting in shunt 2. chronic pulmonary hypertension 3.there is always the possibility of clot just by chance flowing via the PFO

Thanks a lot!)

Do u have lectures on antideppressants and phsych meds in general?

At 15:06 you say cerebral artery instead of cerebellar artery. Question: visual,sensory, memory, motor involved; what part/s of the brain are responsible for this glitch?

NICE VIDEO....

Thank you😘😘

Don't worry. People that speak mandarin won't even need this video to get the highest mark in the class

I do speak chinese, thx a lot!

what are you doing in you tube?

Wouldn't that clot from the calf have gotten stuck in the lungs before getting to the main arterial circulation? Maybe an embolus from the left atrium due to AF could have been the case? :)

you sound a lot like armando hasudungan

excellent 🎩 😁 👕👍Great! 👖

Thank u very much I have an exam and this realy did help A million thanks :-)
