Angiography dye
Common Questions and Answers about Angiography dye
angiogram
How could all this happen after having these Fluorescein angiography test? a reaction to the Dye, but for a few weeks after the test?
What you may be referring to are pulmonary embolisms (blood clots in respiratory system). To test for that can be pulmonary angiography with a catheter device . It's not available at all hospitals, and a trained specialist must perform the test.
Pulmonary angiography is a test used to diagnose pulmonary embolism. The procedure involves a flexible tube called a catheter that is threaded through the groin (upper thigh) or arm to the blood vessels in the lungs.
A dilated blood vessel can be seen on contrast enhanced CT scan. Contrast is a dye injected into the body. This dye accumulates in the brain blood vessels and can be seen on the CT scan. An MRI is a better imaging technique. MRA 9Magnetic resonance Angiography) is still better.
Have you considered or ruled out migraine ? Do you have nausea and any other problems ?
So why expose him to both , the radiation from the thallium nuclear imaging test and the effects of the angiography dye ? Could we instead do a echo first and then decide to either do a thallium ( if there are no risks ) test if there is any doubt and go ahead with the stent process if that is identified as needed?
2) What are the radiation risks of the Thallium test ? I read that the radiation level of this is 590 times that of the exposure during an X ray ? Is this true ?
Pulmonary artery angiography (also called pulmonary artery arteriography) is done by injecting a radiopaque dye into the PULMONARY artery and using CONVENTIONAL X-RAYS to view the dye in the lungs. Angiography is used most often when pulmonary embolism is suspected, usually on the basis of abnormal lung scan results, and is considered the BEST TEST for diagnosing or excluding pulmonary embolism".
The dye that is injected during Ct scan examination is iodine based and rarely causes allergic reactions. As, you mentioned that you were premedicated with prednisolone and benadryl, these are the common precautions taken to avoid any reactions. The common reactions include hives, rash, itching etc. Severe reactions include difficulty in breathing, changes in heart rhythm etc. These are absolute contraindications for this procedure.
Agree about the OCT, the first one I ever had back in 2015 immediately revealed the cause of my own visual symptoms. Now I get one every six months at my ophthalmogist's office. The angiography I have done there once a year still uses the dye, or at least still did about a year ago. I don't know how many optometrist offices have an OCT scanner, but mine does and offers them on an optional basis should a patient want one.
My uncle had gone for Angiography and had a severe reaction of the dye. He is currently unconsious for more than 120 hrs and in on ventilator support. Doctors are saying his kidneys are not working so they are performing hemodylasis to which there is very minimal improvement. What are the chances of such patient recovering and what sort of treatment is advisable in such situation? I would also like to know could the doctors have done something to prevent this situation?
Angiography after the stress test, echo, etc. in all likelihood is to do stent implant. The stress test involves viewing the perfusion of blood flow (contrast agent injected), and apparently there was some vessel occlusions that effected blood flow. The perfusion is viewed with exertion and at rest.
excessive bleeding at the site of the incision,
infection at the incision site, allergic reaction to the contrast dye. Serious complications which are very rare occurrence include blood clots, stroke, kidney or blood vessel damage. It is best that you inform your doctor about this for proper evaluation. Additional diagnostic tests such as echocardiogram may be indicated. Take care and do keep us posted.
Another modality that can be used to assess for aneurysm (other than MRA and angiography) is CT-angiography (CTA). This is a CT scan taken after a dye is injected through a peripheral IV. If the aneurysm is seen clearly, it may not need angiography and can be monitored serially with CTA.
You should discuss your concerns and the options with your physician.
By the way, why did you have the MRI/A performed?
We are being told that Right bundle block suggests Pulmonary embolism or right heart issues, like myocarditis or cardiomyopathy for various and many possible causes including immune reactions and that is why they are treated noninvasively until you better understand the cause, that right block and left block on EKG with high troponin indicate two totally separate courses of action and invasive angiography/dye on a hypotensive is the wrong course for right block/troponin.
My overall health is good (no diabetes etc) and retina is attached. Fluorescence angiography showed dye leakage which was attributed to avulsed vessel (s) and OCT showed an ERM.
I decided to have a vitrectomy after getting the opinion of 2 retina specialists to release traction.
That was 8 days ago. Endolaser photocoagulation was applied and SF6 gas was used.
My concerns:
1. I’m in face down position.
Not think it any thing but he want me to redo another type of MRI using dye to cheek the flow of blood.. My Dr. Asked me how do I feel and I told him fine and he goes on to say well you don't have to go to the er. I am very nervous could this b e and aneurysm.
My Grandmother has been detected with a blockage in heart, and its not getting well by the use of medicines.
Her Doctor is suggesting Angiography now.
Her age is 81 by now. I wanted to take other Doctors opinion about this case.
a) The cardiologist told her she needs to now go in for catheter angiography and that she could have a blockage or lesion. To be frank, he barely acknowledged our questions and wouldn't speak to the connection between myocardial perfusion and severe hypothyroidism. He told us we were "over-intellectualizing" when we tried to ask about the hypothyroidism as it related to the mild myocardial perfusion.
