Transient Arterial Occlusion
Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more
Eye vessel problem: Retinal vein which drains the blood out of the eye gets occluded. This causes blurryness of vision, sometimes loss of vision. It can come suddendly. Elevated blood pressure and patients with diabetes are some of the risk factors. New treatments are available to control some of the problems due to closure of blood vessels in the eye. ...Read moreSee 2 more doctor answers
What does coronary occlusion acute, arterio-sclerotic cardio vascular disease and acute myocardial infarction mean?
Must disagree: This is a bandwagon that seems trendy, but the overwhelming evidence so far suggests that the blocks in the jugular and azygous veins draining into the neck, can be seen in normals as well as ms patients, and there is absolutely no backup congestion blood products found in the brain. This is a risky and absolutely unnecessary procedure, in spite of numerous advocates. No effect on ms. ...Read moreSee 1 more doctor answer
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
See a retina special: A blocked retinal artery (usually from an embolus that traveled from somewhere else in the body like the carotid artery or the heart) can lead to vision loss. It could be a branch or the central retinal artery. There are no good treatment, but a systemic workup to look for the source is required (carotid ultrasound and echocardiogram). A rarer cause is giant cell arteritis. ...Read moreSee 2 more doctor answers
Chronic radial artery occlusion. Pain in hand arterial doppler shows interosseos artery enlarged. Ulnar artery responsbile for profusion. Advice?
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 moreSee 1 more doctor answer
Can be relieved: Renal artery occlusion, a chronic condition can usually be relieved rather than "cured". Cure usually suggests that problem has completely resolved. Complete occlusion of renal artery would mean non function of kidney and can not be cured. 25% of people have two renal arteries and second artery can maintain function in part of kidney. Optimal treatment is stent placement by x-ray interventionist. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
You mean a TIA: Transient ischemic attack (TIA) is often called a "mini-stroke, " and is considered a harbinger for a full-blown stroke. It can occur as a result of a narrowing in the carotid arteries. Unlike a stroke, TIA symptoms last anywhere from 15 minutes to 24 hours. Typically can present with blindness to one eye, paralysis, or slurred speech. You should see a vascular surgeon immediately. ...Read moreSee 1 more doctor answer
See comments: Are you referring to radiology reading of an MRI of brain? In elderly, often thought that white matter lesions are associated with "microvascular angiopathy", sign of potential atherosclerosis. Maybe potential stroke risk, especially lacunar infarct, but not straightforwards. Your physician needs to assess stroke risk. Spots more likely from migraine or prior injury. ...Read more
Yes: The bruit may represent carotid stenosis, plaque blocking the artery. If a piece of plaque or clot breaks off, then it can travel to brain causing cva/stroke. Doppler should reveal nature of bruit. Vascular surgeon may be consulted to do endarterectomy or stent, if merited. ...Read moreSee 2 more doctor answers
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

Anything that creates a blockage of the intestinal tract. You may think of the intestinal tract (stomach, small bowel, large bowel) as somewhat akin to a garden hose. If you kink the garden hose, or twist it, or block it inside, you have created an "obstruction". Most obstructions are a results of previous surgery and most of these ...Read more
