If doppler arterial ultrasound says ulnar artery is supplying flow and collateral flow is good . What is embolism with branch occlusion.

If doppler arterial ultrasound says ulnar artery is supplying flow and collateral flow is good . What is embolism with branch occlusion.

I will try again: There are several cause of arterial occlusions. There are degrees of arterial blockage. If a clot moves- embolize s it can obstruct multiple vessels and branches causing more tissue to be under circulated-ischemic. The remaining question is why the radial clotted: embolus, trauma, needle sticks, thoracic outlet and aneurysm. Need exam. Doppler helps define the location but not the cause. ...Read more

Pectoris atherosclerosis congestive heart failure coronary artery disease dilate hypertension myocardial angina pectoris, what are these?

Cv words: These all refer to cardiovascular particulars. Pectoris = Chest. Atherosclerosis = vascular wall scarring from cholesterol deposit. Coronary artery disease = narrowing and atherosclerosis of heart arteries. Dilate = expand diameter. Hypertension = high blood pressure (within arterial network). Myocardial = heart. Angina pectoris = pain of chest from coronary artery disease, lack of oxygen to heart ...Read more

Is there blood circulation in the coronary arteries?

Is there blood circulation in the coronary arteries?

Yes, except: Yes, except in areas of infarction where the myocardial cells have died. Infarcted myocardium is dead heart tissue. This is usually the result of a myocardium infarction, mi, or heart attack. The purpose of a cardiac intervention: balloon angioplasty or stent, is to save this tissue before the process becomes irreversible. ...Read more

Is coronary artery bypass surgery compatible with varicose veins?

Is coronary artery bypass surgery compatible with varicose veins?

Yes and No: Coronary artery bypass requires some form of conduit for bypass. Superficial veins from the lower limbs have been used for bypass. Smaller arteries from the underside of the chest wall have been used in favor of veins for the left side of the heart. Early enlarged varicose veins can still be used for bypass; however more advanced wall bulges and wall aneurysms Prohibit use of the varicosed veins. ...Read more

Can you naturally reverse atherosclerosis, poor circulation, peripheral artery disease?

You can slow it down: We start to develop atherosclerosis in our 30's and generally it progresses as we age. People who have a family history of heart disease or stroke are more susceptible. You can slow down the progression of this disease by watching your cholesterol, keeping your blood pressure in check, attaining your ideal body weight and quitting smoking. Regular exercise, stress management and good eating helps! ...Read more

Arterial doppler indicates that brachial, ulnar and intraosseous artery are of low resistive pattern. S this normal. Radial artery occluded due to clot?

Unusual: A peripheral artery should have a high resistant pattern on doppler exam. A low resistance may suggest a connection with a vein, arterial venous (av) malformation or av fistula. An injury to the arm may have caused occlusion of the radial artery and also an av fistula. Luckily the ulnar artery is usually the main vessel supplying the hand. Further studies may be needed to define the anatomy. ...Read more

How do coronary artery spasms relate to coronary heart disease?

How do coronary artery spasms relate to coronary heart disease?

Prinzmetal angina.: Spasm can happen in any blood vessel including the coronaries. The inner lining of the arteries have ability to produce a relaxing factor now known to be nitric oxide. However, diseased arteries have dysfunctional inner lining cells that can't make the relaxing factor and thus can present with spasm also known as prinzmetal angina. ...Read more

What is collateral circulation?

Accessory pathways: Collateral circulation is a term used to describe alternative pathways of blood flow that become prominent when a main vessel is blocked. These smaller vessels exist in everyone but are usually very small if the normal pathway is open. Some areas of the body have more secondary branches to provide collateral circulation than others. ...Read more

Why do some people's bodies create very efficient collateral circulation in heart issues such as coarctation? What are factors for success?

Why do some people's bodies create very efficient collateral circulation in heart issues such as coarctation? What are factors for success?

At birth: Great question! you're either born with the potential for collaterals or you're not. You cannot do anything yourself to make them appear. When a vessel becomes obstructed, the hydrostatic pressure that occurs from the "backup" opens the collaterals if they're present. Thus the expression, "your anatomy determines your destiny.". ...Read more

Had coronary angiography and inital results were mixd plaques prox segment 627 of the LAD w/o stenosis and right dominant circulatio. Wt does dis mean?

627?: I'm not familiar with the 627 figure - is this a typo? (i do angiograms). It sounds like you have non-obstructive coronary disease since no intervention was performed or recommended. It means you're okay now, but going to have trouble in the future if you don't take action: you need a statin, eat a vegetarian or mediterranean diet, keep BP and weight under control and exercise daily. No smoking! ...Read more

Is CABG surgery needed if you have good collaterals and micro-circulation?

Maybe: It depends where on the artery the blockage sits, how severe it is, and how many blockages there are. If near the origin and in a large artery, collaterals may or may not be sufficient. It depends on your particular circulation. That's why they do a catheterization with dye and pictures first. ...Read more

What does this mean Other Anomalies Of Pulmonary Artery And Pulmonary Circulation with collateral flow?

Partial description: That sounds like only part of a larger description? Anomalies usually refers to a congenital or birth defect. Collateral flow means blood is reaching its target tissue by alternate routes. Taken all together, my guess is: there is some congenital obstruction or diversion of blood from the right ventricle thru the lungs that, nonetheless, has found a way to get through. ...Read more

Would medication  treat mid LAD 100% coronary blockages effectively. Angiogram showed i had collateral coming from rca to lad. Fyi, my lipid # great.

No: There are no medications that can treat a 100% blockage. Collaterals are good and low cholesterol is good only surgery can treat a 100% blockage, but depending on the flow through the collateral circulation, that may not be necessary. Talk to your cardiologist about treatment options. ...Read more

Can good cardiac collateral flow keep you alive and healthy?

Can good cardiac collateral flow keep you alive and healthy?

Somewhat: Extensive collaterals can be very protective. It is even possible to have a heart attack with no symptoms, and no perceivable damage if the collaterals are developed enough at the time of a vessel occlusion. On the other hand, having occluded vessels secondary to cholesterol plaque isn't exactly "healthy", even though you are feeling well. ...Read more

Cardiac catherization showed100% blockage in LAD & other(oy has collateral). Do i need immediately cabg,  robotic assisted bypass, or just medicine now?

It depends: CABG gives good revascularization with durable, dependable results for most. The risks are dependent on other factors heart and lung and kidney function. If you are stable, work with your doctors to be in the best shape before procedures. The specific coronary anatomy, distal target sites help us guide the choices. ...Read more
