Duodenal Arteriovenous Malformation
Vascular: I will refer this to experts in the blood vessels. Thanks for asking this important question.See 3 more doctor answers
Brain Blood Vessels: In the brain, an avm is typically a twisted tangle of blood vessels where is an abnormal connection between arteries and veins. These can also be present in other parts of the body. Brain avm's carry a risk of bleeding if left untreated. They can also become symptomatic due to seizures and steal phenomenon (altered blood flow).
Can be: Arteriovenous malformation or avm is an abnormal connection between veins and arteries, usually congenital. Sometimes it is hereditary.
Can depend...: Depending on the location (face, trunk, extremities) and level (superficial, deep) and degree of symptoms from the "shunting" of blood from the arteries to the veins the treatment can vary. Thorough imaging (ultrasound, mri, arteriogram) is needed to figure this out. Treatment can involve surgery but more often today relies on injecting chemicals directly into the avm to clog it up.
No: No real treatment unles very symptomatic or riskk oof losing a kidney although the likelyhood of this necessity is small as long as the kidney functions normally. However as you have two kidneys you may not know when and if this kidney faiils without continual followup with your physician and routin urin evaluations.See 1 more doctor answer
Often none: Unless it leaks, there would be no symptoms in most cases. Leaking can cause intense headache or stroke-like symptoms such as focal weakness, loss of speech or vision. Avm discovered after a minor stroke can be corrected before a major stroke. Family history of avm may prompt investigation in someone with no symptoms.See 2 more doctor answers
Bleed risk: The overall risks of bleeding are 3-4% yearly. Each bleed episode carries a 25% risk of mortality. Overall risk of dying is therefore 1% yearly.See 1 more doctor answer
Depends: It can be deadly serious or incidental - depending on the type and location. You should see a neurosurgeon to determine which one you have and what it needs for treatment.
Abnormal vasculature: These abnormal vessels have an increased risk of bleeding. They are treated by open surgery when they are excised, by embolizationby going through blood vessels or by a combination of both. Different methods depends on the size and or location in the brain.See 1 more doctor answer
Abnormal blood vesse: Is an abnormal connection and proliferation of the connection of arteries and veins.See 1 more doctor answer
Brain: Overall risk of intracerebral hemorrhage of 2-4% per year, angiographic assessment is recommended to further define prognosis with AVM. Superficial, moderate-sized AVMs have a good long-term prognosis and may not have any additional benefit with interventional treatment. Lifetime risk of hemorrhage may be substantial for young patients with AVM. Prognosis better than other causes cerebral hemorrhage
Neurosurgery consult: The first thing to do after being diagnosed with and arteriovenous malformation is to see a neurosurgeon. They will evaluate and indicate if it requires surgery which is many times the management of choice. There are certain cases where only observation, treatment for seizures if they are happening and for headaches is recommended. The plan of action needs to be recommended by the specialist.See 1 more doctor answer
AVM Symptoms: Typically, yes. Those symptoms are flank or back pain and bloody urine. A common physical finding is high blood pressure. The caveat here is that these symptoms can also be seen in a wide variety of other renal conditions. Thus, if you are concerned that you may have an avm, please see your doctor for a more thorough evaluation.
Renal AVM: Renal arteriovenous malformations (avms) and fistulas include various abnormal connections between the intrarenal arterial and venous systems. They cause hematuria (blood in the urine, which may not be visible to the naked eye) and are associated with hypertension. Gross (visible) hematuria is the initial symptom in about 75% of patients. Also can get kidney pain due to blood clots.See 1 more doctor answer
AVM: Renal arteriovenous malformations (avms) are uncommon. The estimated rate in large autopsy series is less than 1 case per 30, 000 patients. In clinical studies, which usually include patients undergoing evaluation with urologic or vascular imaging techniques, the incidence ranges from 1 case per 1000-2500 patients.
Renal Arteriovenous: Malformation= a complex tangle of abnormally communicating arteries and veins within the kidney
Renal AVM: Because it is a very rare disorder. The estimated incidence based on large autopsy studies is 1 in 30000 people.
