newfie-girl wrote:Hello all, I have a quick question, if we are taking Plavix or any blood thinner for 3 months, is it unlikely that you will stenose, while on them, or have people stenosed during the 3 month period, while on blood thinners, I am trying to decide wether to go for my follow-up in Barrie, as it has only been 2 months, post-op and i am struggling with this issue.
I guess what I am asking is, wouldn't you have a better picture of blood flow, if you wait for a period of time, after no blood thinners are taken, to check for blood flow and stenosis.
I have to travel a long distance, and really question, wether or not I should wait for at leasr 4-6 months post-op.
Dr. S or anyone who can rspond and shed some info, I would be truly greatful.
Cece, can you remember reading any stats on this ie: stenosis while on blood thinners and what happens once we stop taking them?
Thank you all.........Chris
lets review quickly blood "thinners" we call them antiplatelet therapy or anticoagulant therapy
Antiplatelet therapy, with aspirin and plavix, reduce the stickiness of platelets. Platelets become sticky when the inner lining of the blood vessel is torn and the blood is exposed to the muscle layer of the blood vessel. If these platelets stick to the wall, they create turbulence that results in clot formation. Antiplatelet therapy attempts to reduce the platelet adherence to the blood vessel wall that is damaged by the stretching with the angioplasty balloon.
Anticoagulation therapy alters the ability of the blood to clot by blocking some part of the pathway that leads to blood clot. It is most frequently used to treat blood clots to prevent propagation of more clot. Prophylactice anticoagulation is used to attempt to reduce the risk of forming clot in the first place.
These two methos of "blood thinning" are not mutually exclusive and are often used in combination.
So you ask, when should you have your follow-up doppler study. I think that surveillance is on going. If you develop symptoms of clotting, pain and swelling of the neck, or symptoms of restenosis, such as a return of symptoms after improvement, i thnk you should get an ultrasound.
in the absence of symptoms, i want my patients to have a followup ultrasound at one month, three months, six m onths, 12 months and every six months after that.
my goal is to detect restenosis BEFORE you develop symptoms. Symptoms are bad, recurrent CCSVI cannot be good, otherwise you would not have had angioplasty in the first place.
So why 2 months? I dont know. it is a choice of your doctor.
I guess the bottom line is that you should expect to have surveillance ultrasounds periodically for a long time after treatment. Hopefully they will always turn up normal,
