Only one carotid artery?
 

Hi everyone

I posted my history of concussions in another thread. Hockey, in welcoming me to the forum, urged me to get a Neuropsych evaluation ASAP. Well, I got referred for this, but in a weird way. I had an MRI of my pituitary, because the levels were going haywire. Turns out the pituitary is intact, with no tumors. My hormone levels are still haywire. What was weird was that the MRI revealed that I have only one artery that carries blood to the brain, on the left. On the right, where the other one is supposed to be, there is--nothing. My first thought was that I should have read through that entire parts list before exiting the spacecraft. The endocrinologist referred me STAT to a neurologist (only way I can explain getting a neuro appointment the next week) for referral for a full neuropsych workup. Evidently, the left one is a little bigger to take up the slack, but there probably have been some cylinders misfiring all along. Weirdest thing I've heard of in about three days.

Has anyone out there ever heard of having only one carotid artery? Anybody got a spare one, Right side, 1952 model?

thanks

:eek:Wow! All these years and all the problems you've had to deal with and nobody ever spotted this major "structural defect." It just goes to show, once again, how shabby the treatment for folks with brain injuries/issues really is. Seriously, if you'd been having chest pain do you think it would have taken this long to discover a missing valve or blocked artery?

Do you have this massive urge to gift wrap your scan and send it to all the doctors who ever dismissed your symptoms as minor or psychological? I loved your joke about the aliens and admire you for being able to keep your sense of humour through all this.:BeamUp:

Keep us posted as things move along and know that we are all pulling for you.

Cheers

Thanks for the Wow!, Hockey. To be honest, I don't know how scared I'm supposed to be with this thing. I'm also wondering if the seven years I spent studying martial arts in my 30s and 40s damaged anything. I studied Aikido, which is a spiritual art and strictly defensive, but you do a lot of rolls and get thrown down a lot. I never concussed (to my knowledge) during this time because you're trained to fall. That training never leaves--recently I tripped on new pavement and fell flat on my face but the only thing hurt was my glasses. Of course, I guess that was more G's applied to the brain. I must have been thrown on the mat hundreds of times during those years. And here I had been begging to get back on the mat and the doctors still were saying no. Glad I didn't.

See, when someone in 1987 tells you that something is insignificant, you tend to file it away, because of the authority we give to doctors. Nobody every caught the missing artery because they weren't scanning that low in my cranium. Aliens? I thought that all of us came from a spaceship. I do remember the parts list--it was 680 pages long and I had a headache anyway.

More later. It's almost Yom Kippur

I believe you are supposed to have two arteries on each side, an internal and external carotid artery.. There are many older people walking around with a blocked carotid artery, which can cause a stroke. If you were born with one missing, then your body has probably compensated with what you were born with. However, it is important that you be careful about your diet and blood pressure to prevent the build up of plaque in the arteries.. With only one you would be at a higher risk of transient ischemic attacks or worse, stroke.

We have two vertebral arteries that feed the same areas. They usually only pick up a small portion of the load. Maybe yours were picking up more than usual.

I can imagine an ultrasound technician trying to do a carotid ultrasound and not finding a blood flow signal. It would be interesting to watch him try to figure things out. Can you imagine someone trying to take your pulse on that side? They might think you are dead.

Maybe you want to get a tattoo that says "No pulse this side."

Did you have a normal MRI or was it a MRI/MRA. MRI's do not show arteries as well as MRI/MRA's do. With an MRA, they first do an MRI, then repeat it leaving out the blood signal. When they subtract the second image from the first, what is left is the signal or image of the blood.

I have seen mine. Very interesting. I have a 'pouch' in one of the vertebral arteries just above where it exits the vertebra.

Hi Markinidaho

I had a normal MRI for the pituitary in which someone noticed the "missing artery." There is a sort of pulse on the right side. The neurologist ordered an MRA which I'll have this Monday. He wants to see if it was never there or was damaged. If it was, it was probably when I was 11 months old and I went out of my crib onto my head and fractured my skull. The neurologist also ordered a thorough sleep study again since I have a history of central apnea, and a neuropsych exam. There is evidence that the left artery is somewhat bigger, probably to compensate. The guy said that if you are born with this, it's "no big deal." Typical.

One Carotid Artery!! : )
 

Hello! ;) It is great to finally meet someone like me!! : ) I have been a marathon runner for 17 years. (I was five minutes away from qualifying for Bostons marathon 2008 so close..: )) I also was born with only have one carotid artery! Do not be scared! At birth your brain compensated for the lack of a secondary carotid artery. You formed more pathways in your brain to allow the brain to be well supplied with blood and oxygen. I recommend exercise! Keeping yourself healthy is the best thing you can do! Reducing your risks of blood clot, high blood pressure, plaque build up or stroke would be something to think about for when you are in your eighties. (Quit smoking or drinking if you do either or both!)
Don't get scared about one carotid..You are just unique like me! : )

If you have questions let me know. :)

having one Carotid Artery
 

I to have only one carotid artery. My left carotids were severly damaged while in surgery for a bone fusion in the Cervical area. i was told that the drill slipped, caught the carotid and mangled it. This happened 30 years ago. My last MRA showed the right carotid had expanded to carry the blood flow. The basal artery in the back of the head, had also grown to accomadate the blood flow. The Circle of Willis was also fine. i am so blessed to be alive. I have Horners Syndrome on the left eye, as part due to the lost of the Carotid on that side. From what I have been told when this happened to me I was only 1 of 2 people that survived aaccident like this.

The doctors like in the ER look at me like I am crazy, when tell them I don't have an artery on that side. When they go to listen, they have a priceless look on their faces. Another thing that I have is PTSD, I play that in my head over and over again. The trauma is what I went through after the operation. God has been good to me. I should have been dead. I am writing a book about that ordeal.:D

One carotid artery!
 

With on carotid artery, how old are you all? Are you taking a asprin daily? What are you doing to keep healthy?

Recently achieved a massive headache at a very inappropriate time on my
55th birthday. With my head still a little sore, went to the doctor; got an MRI/MRA and found something very interesting, 100% blockage in my left interior carotid artery. I'm curious what you folks have been told about longevity, how it affects your life, etc. Doc seemed to downplay it but as I was leaving said "wouldn't let a chiropractor adjust your neck". That kind of freaked me out but have yet to find anything conclusive about living with just one. I have been active my whole life (grew up a swimmer) and in relatively great health. Was diagnosed and treated for testicular cancer which I found out on my 40th birthday. Other than that, always healthy and stayed away from doctors, guessing I need to stay away from major birthdays as well. cjes

only one carotid
 

I am 57 years old have carotid on left side . Question how many people in the United States with same issue Mel1

good to talk to you again
 

:)hello people like me please send more info. mel1

Only one carotid artery
 

Wow I was diagnosed with this after months of severe headaches and a cat scan...Problem I have now is that I suffer from very high blood pressure at 32 years old and with the headaches now back I wonder what damage is being caused by only having the one carotid and what the future holds? Does anyone else suffer from any additional problems?

Thanks

hello bombay this is mel1 I want to know how many people in the united states that were born with only one carotid working may we could have a gathering.

Hi bombay, I sorta have been wondering myself what the future holds. I get headaches sometimes too, but I have no poblems with blood pressure though. I have had problems with blackouts, dizziness, and strange vision problems. Being 15, Im curious to know though if you had problems as young as me with your missing artery and whether or not my problems are unique, or if others have suffered from blackouts and dizziness as a result of this. Im relieved to find that there lots of people seem to be living average lives with this, Im just trying to find more information on this. So far the doctors have been of no help :\

Hi Dgman
I did suffer from blackouts when I was young and this nearly killed me as I passed out onto a large ceramic bowl which shattered in my back so you will need to be carefull if you are suffering from these, my high bp did not start until my mid 20's and at around 28 the doctors wanted to put me on tablets I managed not to have them for another year or so but I am on many different tablets now, This may not be the same for you or for others but I believe if they put the whole population together for which in the UK I am 0.000013 who has this condition however that ratio works out I could imagine that many would suffer from high BP and enlarged veins at the back of your head that try to compensate for the missing artery, continue to push your doctors to support you and all the best for the future, (I had to go private to get anything done for myself so this may be something your parents may want to consider)

Thanks for the reply bombay. So far my blood pressure seems fine, I guess I'll see where that goes sooner or later. I'm glad to hear that it isn't just me with the blackouts and all. I know how dangerous it is though since I was riding my bike and passed out in the middle of the street. Last doctor I went to said that more salt and water would help, since that would allow blood to flow through one of the three arteries a little easier, which has sorta helped the blackouts to be less frequent. Anyways, thanks for the advice

I have on one carotid artery. On my right side. Had a hemangioma on left side of my neck removed when I was 10 months old. Had a massive stroke as a result from doctor severing artery. I'm now 54 years old. Never had any problems, always been active and healthy. Ride a bicycle 30 miles a day 4 times a week.

14 Year Old Son
 

My 14 year old son was diagnosed with a double fusiform aneurysm in his left carotid artery in his cavernous sinus in January of 2011 after being seen in the emergency room for severe migraines. It had been stable for a year or so but began to grow rapidly this past year. It grew 50% in 3 months and the Doctors at Johns Hopkins want to close his left carotid artery. I see that there are people on this forum who were born with only one but I am terrified of what closing off one will do to my son. They are going to do an occulusion first, see if he needs a bypass and then close it. They are informing me of risks like stroke, brain damage, death. It is all very scary and I am not telling my son any of these risks. Has anyone heard of any success in closing off one carotid? They doctors say it is rare and especially rare in a child/teenager.

Only One Carotid artery
 

My Mother recently had a scan of her brain and head (had a clot go boom behind her eyes and is at risk of stroke; managed by meds) and the doctors discovered she only has One Carotid Artery~she doesn't have one on the left. I was like "how the heck have you been living and breathing your whole life?" The doc told her she either was born with only one or ? they couldn't really explain it.
Wonder if you and my Mom are related? lol

LadyAlaise,

This thread has not been followed since July of 2013. The last poster never even posted a second post.

Hello LadyAlaise,
Welcome to the NeuroTalk Support Groups.
As Mark explained the poster hasn't posted in a very long time.
However, we do have a Stroke Forum

If you need any help with the forum features, please just post again and someone will help you.

take care.

Love your sense of humor!

Also missing a carotid artery
 

I know this thread is a bit outdated but i was also born with my right internal carotid artery. This was found when I was 8 years old after I walked into a mailbox and had an MRI. Nothing really came of it until I was 19, when I was diagnosed with 2 brain aneurysms. The doctors say that I was more at risk for brain aneurysms because of the increased flow in the other arteries. I had brain surgery to clip and coil those two brain aneurysms. I am now 26, have been diagnosed with 2 more small aneurysm that have not been treated yet. I am 8 months pregnant with my first child and hope to have surgery on the two untreated aneurysms soon after my baby girl is born. It is very interesting to me to find other people with this same defect!

Also missing!!
 

I was diagnosed 5 years ago. Have bad headaches, auditory issues, ballance and memory problems. Going to UTSouthwestern to see a Dr. that specializes in rare brain/arterial disorders. Glad to meet all of you!!!

One carotid for 84 and counting!
 

Hi,

My father in law ten years ago also realized he has only one carotid. He is almost 84 years old and he is very healthy. sometimes (rarely) he suffers altitude sickness or dizziness but in general he is very healthy but obvioulsy he takes care about his alimentation habits. This morning we were talking about this rare condition, I googled it and found this forum, it is amazing how the human body finds the way to compensate and works properly for an entire life. Please let me know if there is some specific care for the condition for my 84's father in law. (by the way, that comment of having a tatoo saying "no pulse here" is the best!) Regards.

I read this thread and saw your post about a stroke forum. I tried following the link, but it did not work. Is there still a stroke forum? Thanks so much for any help you can give.

Hello Bashful_One,
Welcome to NeuroTalk,

Yes, there is a Stroke forum. The link works fine for me.
