covid 19-cerebral venous sinus thrombosis and the vaccines


thrombosis means blood clots
the most common blood clot that most of know about is the one you can get in your calf
also we all have heard of folks getting blood clots to the lungs called a pulmonary embolus

a blood clot can form anywhere a vein is located

a rare location is the cerebral venous sinus in the brain

a blood clot in this area the cvst or cerebral venous sinus area occurs 4-6 times per 1 million people each year
a blood clot in the leg occurs 1240 per 1 million people each year
a pulmonary embolus occurs 600+ per 1 million people each year

so a cvst or cerebral venous sinus thrombosis or blood clot is a rare event

the blood flows up from the heart through the arteries via the carotid arteries
it goes into the brains smaller arteries then eventually gets into the vein or venous system
this is where the cerebral venous system or sinuses are located
the link above is a lengthy scientific discussion of cvst or cerebral venous sinus thrombosis

a clot in this area can cause headaches nausea vomiting seizures coma and other neurological symptoms

its a medical emergency

a blood clot to the brain we hear about usually occurs in the artery system
eg folks with atrial fibrillation can form a clot in the heart chambers which will break lose and get lodged in the brain causing damage to the areas that that artery supplies
most strokes we see are these

in the general population the incidence of cvst or cerebral venous sinius thrombosis is 4-6 per million each year
in those who get a covid 19 infection the incidence of cvst is 39 per 1 million people
so far in those who get the moderna or pfizer vaccine the incidence is 5 per 1 million people
so far in those who got the astra zeneca  vaccine the incidence is 4 per 1 million people
so far for those who got the johnson and johnson vaccine the incidence is 1 per million

you are about 10 times more likely to get cvst or cerebral venous sinus thrombosis if you get a covid 19 infection than if you get one of these vaccines

the cvst or cerebral venous sinus thrombosis is a rare rare event when it happens

what is different with the cvst that you get with the covid 19 or the vaccines is that antibodies develop against the platelets in the blood that makes the blood clot 

the usual cvst that is seen in medicine the blood clot forms via a different mechanism
that one you treat with heparin
the covid 19 cvst is not treated with heparin since it will make things worse since the platelet count drops in these patients and the heparin makes things worse

these are the facts the cdc are looking at

do you let 10 times more cases of this to occur in people who dont get a vaccine and get infected with covid 19 
do you give the vaccines knowing you will protect 9 out of ten people from getting cvst from the covid 19 infection
knowing 1 out of 10 of them will be harmed by cvst from the vaccines

you save 9 and harm 1

or one way to think of this is that you actually overall you save 999,999 and harm 1 person

thats the math of cvst  or cerebral venous sinus thrombosis in covid 19 as i understand it
