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
Yes: Usually for re-stenosis most surgeon will perform stenting if indicated instead of redo surgery although no true benefit of stenting over surgery in these cases. In acute sitting , yes stenting is being done to repair a post carotid surgery flap or dissection. ...Read moreSee 5 more doctor answers
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
None: Calcification of any artery, by itself, does not warrant any type of intervention or follow up. If that calcification is associated with a stenosis ("narrowing") of the artery, then that may require follow up and/or an operation. The carotid arteries are very often calcified and if associated with a high grade stenosis, may portend a higher risk of stroke. Discuss with a vascular surgeon. ...Read more
Heart vessel therapy: Percutaneous transluminal coronary angioplasty (PTCA) is the opening of blocked heart arteries with a balloon. An artery is stuck and a wire is passed in the system until reaching the heart arteries. A balloon is passed over the wire to the area of blockage and inflated. The blockage is flattened but it can return. So most patients actually get stents placed. Stents require blood thinners. ...Read moreSee 1 more doctor answer
Carotid artery disease, different results from duplex ultrasound vs. Ct angiogram (cta), is that possible?
CT angiogram: It is being done much more often when it is necessary to visualize blood vessels (for example to see if there's a blockage). There is some radiation involved but it is considered much less "invasive" and has less complications than the regular type of "angiogram", where blood vessels are visualized by inserting thin tubes called catheters directly into them to inject a dye. ...Read moreSee 2 more doctor answers
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
Which procedure is more useful to detect artery blockage, angiography, CT angiogram, or cardiac catheterization and why?
Step by step: Hello leenicole-- coronary artery bypass ad graft surgery is done in a strict step by step procedure involving first obtaining the bypass graft vessels -- which could be veins in the leg or arteries in the arms/chest -- then the sternum (chest bone) is split and forced open to access the heart in full view and the blocked vessel is bypassed -- etc. ...Read moreSee 1 more doctor answer
Carefully: The distal end of the internal mammary artery is anastomosed to the coronary artery distal to the atheromatous plaque using 8-0 polypropilene and high power magnification. Radial artery or grater saphenous vein grafts are anastomosed to the ascending aorta and tho the coronary distal to the plaque. Obviously the thorax has to be entered and cardiopulmonary bypass may or not be used, . ...Read moreSee 1 more doctor answer
