Doctor insights on:
Ct vs cath: In simplest terms the ct angiogram would be safer than a coronary angiogram, however, they are usually used in different circumstances. The ct angiogram is useful as a screening tool to see if coronary disease is present. A cardiac catheterization is performed when a patient has an acute coronary syndrome or a myocardial infarction to evaluate coronary disease, or even treated. ...Read moreSee 1 more doctor answer
Both safe: Both also have risks such as radiation and contrast usage. Coronary arteriography has small bleeding risk at puncture site. Need to get the right test for your problem. Coronary arteriography is the gold standard. ...Read more
No screening: There is nothing called screening for mesenteric stenosis. If you have no symptoms then you no need to screen for occlusion. If you have chronic symptoms then duplex ultrasound is a good starting test but has a lot of limitations. In cases of acute ischemia then ct scan is best to start with. ...Read moreSee 2 more doctor answers
Doppler Ultrasound: Ultrasound has proven to be cost-effective and quite accurate in determining the degree of narrowing in the carotid artery. Many vascular surgeons, including myself, solely rely on it to decide whether someone needs an operation. Mra is not so good and over-estimates the actual degree of narrowing. I would not rely on its findings to decide on operating. As mentioned a cta is much better. ...Read moreSee 1 more doctor answer
Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?
Coronary Angiography report concluded;"atherosclerotic coronary artery disease showing moderate proximal LAD mixed stenotic lesion 50%"what it means?
Test Result: I find it is best to discuss any test result with the physician who did the test or ordered the test. They can interpret it knowing all the clinical history involved and tell you exactly what is going on. ...Read more
Carotid doppler showed 50% bilateral blockage, mr angiogram was negative. Which is more accurate?
Debatable: Few vascular surgeons make decisions on carotid artery stenosis based on mr, as carotid doppler (ultrasound) has been proven to be very reliable when a good technologist performs the study. From what you're describing, your carotid arteries are likely without disease as the reporting standards for ultrasound haven't quite been set. In my lab you'd likely be found to have no disease at all. ...Read more
Intestinal angina.: Mesenteric ischemia occurs when the blood supply to the intestine is insufficient to maintain it's normal function. When acute, it may lead to infarction of the intestine, which is life-threatening. When chronic, it may cause a nagging intense pain after eating, analogous to angina. ...Read moreSee 3 more doctor answers
Carotid artery disease, what to believe, if different results from duplex ultrasound vs. Ct angiogram (cta)?
May be: Echocardiograms are very good at seeing the function of the heart muscle. If coronary artery disease has damaged the heart, the weekend part of the heart will be visible on an echocardiogram. However, significant blockage can occur without damage. A resting echocardiogram will not be able to see this. A stress echocardiogram, however, may be effective in detecting this type of disease. ...Read moreSee 1 more doctor answer
3 major factors: Condition of the artery (caliber, plaque, injury, inflammation...) viscosity of the blood (hydration, tobacco, blood element derangement...) and the force of the blood flow (stasis, poor heart functions...) are the main factors leading to mesentary arterial thrombosis. It can happen in association to an embolic event. ...Read moreSee 2 more doctor answers
