Superior Mesenteric Artery Stenosis
No: One operation can usually fix the constriction. ...Read more
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
I was just diagnosed with msa syndrome superior mesenteric artery syndrome and was wondering what kind of procedures I will be facing?
I've been told that I need surgery to treat superior mesenteric artery syndrome, what other options do I have & where should I go for the operation?
Discuss with MD: Superior mesenteric artery syndrome is a very rare, life-threatening gastro-vascular disorder characterized by a compression of the third portion of the duodenum by the abdominal aorta and the overlying superior mesenteric artery. Your abdominal surgeon can direct you to the next step as well as your primary care physician. You should not delay getting the evaluation, . ...Read more
Try: Mesenteric doppler first. Then cta if needed. ...Read more
An MRA confirmed that I have nutcracker syndrome in my left renal vein and right hepatic artery arising from the proximal Superior mesenteric artery. Could this be the cause of my uncontrolled BP &HR?
Yes: Limitation of blood flow to a kidney will typically raise BP. Often in such a case the BP will be very difficult to control with meds unless the blood flow is restored. A stent in the renal artery may help, but there are several studies suggesting that if meds can control the BP, then procedural risks may not be warranted. You should consult with a vascular surgeon or interventional radiologist. ...Read more
Could you please tell me what the symptoms of mesenteric artery stenosis would be also pooping bright red blood a lot of tummy pain?
Dx'd w/medial arcuate ligament syndrme via CT, US, and Angiography shows decrease blood flow in celiac artery, backflow of blood in mesenteric artery. Could this be cause of abd pain, nausea after eating? Might surgery help?
MALS: Median arcuate ligament syndrome certainly could be the cause of your pain, and surgery could help, but you have to exercise a lot of caution here. It is what we call a diagnosis of exclusion, which means that we have no way to prove that it is the cause of your pain. I always recommend before undergoing surgery that you have a second opinion at a major university gastroenterology department. ...Read more
Upper abdominal pain, took gall bladder out, now different pain in same area, doppler scan shows 60-90 percent block in superior mesenteric artery, ?
Many possible causes: There are many possibilities but severe blockage of abdominal arteries certainly can cause pain and other symptoms. You need more workup and possible treatment. ...Read more
What could cause peak systolic velocity of right internal carotid artery to be elevated to 130cm/s but no elevation in left ica & no stenosis found?
Carotid disease: Any blood vessel may have a "blockage" due to internal clots/plaque or external pressure. The blockage can be graded and thus roughly estimated to be 25, 50, 50-75, more than 75%. Occasionally 60% is used as a cut off. Those numbers help to compare but also help to determine if blockage is significant enough to cause harm. Less than 50% says it is not significant. Test can monitor changes. ...Read more
Claudication: Which means cram like pains in the calves with walking which gets better with rest and returns with walking. The distance of walking that brings out the pain is called the claudication distance. The shorter the distance the worse is the stenosis. Also, in severe cases the leg loses hair and becomes painful at rest with elevation better with dangling. ...Read more
Will try: Renal artery stenosis is a blockage of the blood flow to the kidney. This may be associated with high blood pressure. It can be diagnosed with a doppler ultrasound of the renal artery in suspected individuals, or some form of a renal angiogram (such as ct or mr angiograms). The stenosis can be dilated sometimes resulting in a decrease in blood pressure levels. ...Read more
Depends on type: Young people are different than older ones. The disease is slowly progressive esp in the atherosclerotic variety usually in older patients. So, newer research suggests that observation is equivalent to aggressive intervenion in most cases due to similar outcomes. ...Read more
Renal artery stenose: 52 F asks prognosis of RAS. ANS: I specialize in this for over 50 years. A complex question that deserves a 2nd opinion from me. Depends on cause, prior treatment, other problems but almost all can be managed today by BP meds. ...Read more
Stenosis: Stenosis is narrowing so renal artery stenosis is narrowing of an artery that sends blood to you kidney. The effect usually is your blood pressure goes up and in my experience this is the most difficult kind of high blood pressure to manage using medicines. It usually requires some kind of repair - surgery or dilatation. ...Read more
Elderly Hypertensive: Carotid stenosis usually occurs secondary to longstanding atherosclerosis. Risk factors include high blood pressure, diabetes, and coronary artery disease. It takes time for atherosclerotic plaques to develop, so most patients with carotid artery stenosis are older adults. ...Read more
Yes: Patient with carotid stenosis should be on anti platelet medicine like Aspirin or Plavix, also if tolerated, must be on a statin (cholesterol lowering medicine) like Lipitor (atorvastatin) to stabilize atherosclerotic plaque and prevent its progression to worse stenosis. In cases of symptomatic carotid stenosis above 50% then surgery is better than just medical treatment. ...Read more
High blood pressure:
Patients who have uncontrolled blood pressure despite 3 or more medications at maximal dosages are considered for possible secondary hypertension. Ras is a cause of secondary hypertension.
Also people who are younger than 35 or older than 65 who develop sudden or new onset hypertension, are usually screened.
Unexplained renal failure especially with different sized kidneys should be screened. ...Read more
Yes: You should be on an Aspirin and a statin. Both lower your risk of a stroke, but neither will make the carotid stenosis go away. ...Read more
Carotid artery stenosis means that the carotid arteries have blockage, usually in the form of atherosclerosis. This can cause stroke. The more severe the blockage, the greater the risk
in the absence of neurological symptoms, most cases can be handled with medicine and close periodic follow up by a vascular surgeon. However, if the blockage is more than 80%, surgery will reduce the stroke risk. ...Read more
Narrowing: "stenosis" means narrowing. Most commonly stenosis of the carotid artery is from atherosclerotic disease, or hardening and buildup of plaque within the artery itself. Atherosclerotic disease of the carotid artery is implicated in stroke and is best monitored by a vascular surgeon, who can easily follow the degree of narrowing by ultrasound on a periodic basis. ...Read more
