What is porto-systemic collateral circulation?

What is porto-systemic collateral circulation?

Abnormal: It is the type of circulation that develops as a result of a compromised blood flow through the portal vein that passes through the liver secondary to scarring of the liver caused by perpetual inflammation. This condition is known as liver cirrhosis, which usually develops as an end stage of the inflammatory process. ...Read more

It's usual: It is very usual. In fact, it develops when main arterial flow is compromised by the developing clolesterol plaques. ...Read more

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

Brachial artery shoes triassic flow but with blunting if the dialostic component and suggests collateral distal flow. What is collateral distal flow?

Collateral : Means additional blood vessels. Distal means further away or running towards the extremities, if you have collateral circulation this is a good thing..... ...Read more

How unusual is cardiac collateral circulation that supplies the heart?

Quite common: Collateral circulation is quite common in people who have progressive development of coronary artery narrowing. Several examples of collateral circulation are normal consequences of the native coronary circulation. ...Read more

What does collateral circulation mean?

What does collateral circulation mean?

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

Diagnosed with total right radial artery occlusion with collateral flow in ulnar and intraosseous artery. Occlusion due thrombus. What does this mean?

Diagnosed with total right radial artery occlusion with collateral flow in ulnar and intraosseous artery. Occlusion due  thrombus. What does this mean?

Clot in your artery: A blood clot in your artery can occlude the blood flow to your hand, fortunately there are other arteries that can compensate for this. Unless you had trauma to that arm , you should see a hematologist or internal medicine doctor to be worked up to rule out a hypercoagulable condition. You should disclose this to your surgeon if you need surgery in the future ...Read more

Dopplerultrasound shows chronic radial artery occlusion with collateral flow in ulnar and intraosseous artery. In pain at elbow and wrist. Need help?

Dopplerultrasound shows chronic radial artery occlusion with collateral flow in ulnar and intraosseous artery. In pain at elbow and wrist. Need help?

Radial artery: in 80% of people the ulnar artery is the dominant artery bringing blood flow into the hand. It is unclear as to why you have a chronic radial artery occlusion, unless there was some evidence of trauma or arterial line placement. I would recommend that she be evaluated with regards to the pain at the elbow and wrist, but most likely this is not secondary to arterial insufficiency ...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?

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

Ultrasound shows features of chronic total radial artery occlusion with collateral flow in ulnar artery. Can this affect pregnancy.

Ultrasound shows features of chronic total radial artery occlusion with collateral flow in ulnar artery.  Can this affect pregnancy.

Not likely BUT...: If the radial artery occlusion is an isolated finding, perhaps from an old injury, then there should be no risk to the pregnancy. However, if you are, or were, a very heavy cigarette smoker and especially if you are diabetic then your radial artery problem could be a symptom of a more general vascular pathology which could have a negative impact on your pregnancy. ...Read more

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

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

Does blood flow from the anterior communicating arteries to the anterior cerebral arteries?

Does blood flow from the anterior communicating arteries to the anterior cerebral arteries?

Not exactly: The flow to the anterior cerebral starts at the heart, goes up the ascending aorta, to carotid arteries which reach the Circle of Willis, and go to anterior cerebral, middle cerebral and posterior cerebral arteries. Anterior communicating can be viewed as a bridging collateral. ...Read more

Does distal fibula fracture have good blood supply?

Does distal fibula fracture have good blood supply?

Distal fibula: Yes. Generally the distal fibula has a good blood supply and heals reliably well. Metabolic problems and lack of immobilization can lead to non-union of a distal fibula fracture. ...Read more

Chronic total radial artery occlusion in right hand with collateral flow in ulnar and intraosseous artery. What course of action would u.Advise?

Probably harmless: I doubt that cto of the radial artery will cause much problem. I harvest the radial artery frequently for coronary bypass, usually in the non-dominant arm. As long as you have good ulnar collateral refill, it wont cause you any long term problems. ...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

I have total right radial artery occlusion with collateral flow through ulnar and intraosseous arteries. Is this a good thing or bad? What i'd collat

I have total right radial artery occlusion with collateral flow through ulnar and intraosseous arteries.  Is this a good thing or bad? What i'd collat

Not a good thing but: The dominant circulation to your hand in 90% of patients is through the ulnar artery. So unless you are one of the other 10%, there should be no major vascularissue; i would need to know what the cause for your artery occlusion was to further answer you. Patients with poor circ to the hand may experience cold intolerance, decreased strength, hand pain and soreness. ...Read more
