Complete Occlusion In Left Artery
There is a complete occlusion of the distal verebral artery on the left after entering into the foramen magnum. What does this mean?
This is a congenital malformation or the results of a "stroke....more information is needed.
Hope this is helpful

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
How serious is an occlusion of the left circumflex artery if your heart is left-side dominant? Would an MI from that likely be fatal?
MRA shows possible right vertebral artery occlusion, second MRA shows the right vertebral being a lot smaller than left. Is it occluded or small?!
That is a question-: -U need ask Ur provider. 2 MRI's of the same area can show occlusion or narrowing, as the position of the patients may vary a small amount, & the true pathology may not B Cn. ...Read more
Basilar artery: Basilar artery is formed by the confluence of the vertebral arteries. Vertebral arteries are branches off the subclavian arteries. They supply the posterior aspect of brain and flow into the circle of willis. Vertebral occlusions can occur due to atherosclerotic disease and dissection from trauma. ...Read more
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 more
Depends: "occlusion" means 100% blockage. "stenosis" means <100% blockage. If you have abrupt or very recent occlusion or stenosis, the artery can be dilated and stented using a wire & balloon (angioplasty). If there is chronic occlusion, the kidney has been permanently damaged and there's no benefit in doing anything further to the artery. ...Read more
Can you tell me in occlusion of the femoral artery at the level at which the profunda femoris is given off, arterial inflow to?
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 more
Atrophy: If the vessel is truly totally occluded the kidney will shrink or atrophy. As long as the other kidney is ok, you should be too. See a good nephrologist and endovascular suegeon. ...Read more
High blood pressure:
If your artery to the kidney is completely blocked, there is no reason to restore flow. However, you should be sure that it is completely blocked, rather than a very tight narrowing, which would require treatment.
The artery to your second kidney should be monitored to make sure that there is not an issue there. Losing flow to both kidneys would result in kidney failure, and dialysis. ...Read more
See below: The gold standard for detecting renal artery occlusion is a renal angiogram, which is injecting a iodinated dye into the blood vessel and taking images. The dye itself can cause some reversible renal injury, and should be used weighing the risk and benefit. Other rare but serious complication is cholesterol embolii syndrome. Other tests eg ultrasound and MRI may not be conclusive. ...Read more
Not so common: Depends on your age, BP level- less than 1% of patients with moderate or gr 2 (BP more than 160/100) high blood pressure will have renal artery stenosis or blockage. More common in caucasians than african americans. Usually don't have to screen for ras unless patient is on multiple medications, unable to tolerate medicines, severe high BP requiring hospitalization or kidney function is affected. ...Read more
Yes: The most common cause of renal artery stenosis is an obstructing plaque which is due to atherosclerosis. A history of smoking, high cholesterol, high blood pressure and diabetes can cause a blockage to form in these arteries. Another rarer cause is blockage due to thickening within the arterial wall due to inflammation. This tends to occur in women, usually 30-50s, with little or no other risks. ...Read more
I was diagnosed with heavily calcified arteries and a 99 percent occlusion of the LAD through an angiogram. I had no symptoms. How is that possible?
Yes: There are inherited disorders of clotting that can predispose you to arterial disease in the kidney and elsewhere. Additionally there are familial disorders of metabolism that cause accelerated atherosclerosis. A strong family history of premature arterial disease or heart attacks raises one's suspicions. These conditions can be mitigated through judicious use of medications. ...Read more
Periph. Art. Dis.: Yes & No. Atherosclerosis is slowed by using meds. Such as antiplatelets (aspirin etc etc), potent statins (atorva., rosuva, .etc);ACEI's (lisinopril etc) or ARB's;some betablockers, and other meds such as cilastozol etc. A complete or high grade occlusion however will need either antegrade or retrograde mechanical revascularization as well as meds. If in area seek my practice out as we can help ...Read more
Not correctable: Occlusion of the vessel can occur from a plaque, clot, emboli, irregular heart beat, etc. Eye can worsen (glaucoma/pain) even if vision improves some, which is rare. The important task to do is to prevent more events in eyes and brain, see your family doctor to determine what caused this occlusion. ...Read more
Is it true the heart can build more capillaries with strong diet and exercise? Can it save you from complete occlusion of artery?
Great question: Its true the heart can grow its own bypass, a very providential fact when it comes to survival. ...Read more
radial artery is narrowed in calibre with eccentric calcific foci in its midportion causing partial occlusion. What is calcific foci?
When you have a disease that causes occlusions in digital arteries (toes, not ankles or above), w/o gangrene, what is the best exercise or other lifestyle tip to accelerate healing & collaterals?
Walk: In general, a walking program is all that is needed. Work out the detail for your personal best results with your physician. ...Read more
Radial artery: Occlusion may or may not be symptomatic depending upon the level ie wrist, forearm level, the collateral circulation ie other avenues for blood flow, the pattern of the baseline circulation to the hand and fingers as some have a radial artery that never contributed much to the hand ie an ulnar dominant pattern and if the thrombosis itself is causing symptoms via alternative nerve pathways. ...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
