What is an arteriovenous fistula?

Arteriovenous (AV) fistula is a potentially serious condition characterized by abnormal arterial and vein. The treatment of this condition depends on the location and size of the fistula. The complications associated with the formation of AV Fistula include the formation of blood clots and heart failure. The blood gradually begins its path in the artery and passes through the capillary before it reaches the intended vein. In the presence of an arteriovenous fistula, the blood of an individual passing through the capillary skips and goes directly into the vein. These small blood vessels are usually used to supply the body tissue with oxygenated blood; Therefore, when the capillaries are deprived of blood and nutrients, they are also their related tissues.

Arteriovenous fistula is a condition that can be congenital, which means it is present at birth or can be obtained. When AV fistula is diagnosed as a congenital condition, it is generally more pronounced in the lungs and is the result of the presence of a secondary condition, such as the rendu-osler disease (Rowd). Individuals who underwent surgery such as cardiac catheterizationThey can develop AV fistula as a complication. The occurrence of deep punctures, such as the occurrence of a shot, can also contribute to the formation of AV fistula. Arteriovenous fistula can also be artificially created for treatment purposes, as is sometimes necessary in dialysis.

Individuals who develop and fist in their limbs often remain asymptomatic, which means that they do not experience any symptoms at all. Asymptomatic individuals generally do not require any treatment and experience with other complications. Those who develop more pronounced fistulas that have a larger size tend to experience different, persistent symptoms and symptoms.

Often, if the fistula is located in the limbs, it can develop swelling in the affected pendant. The skin in the affected area can also accept a red shade or demonstrate a living break. When the lungs evolve AV fistula, symptoms manifest differently and can lead to life -threatening complications.

individuals with pulmonary arteriovenous fistulas can experience shortness of breath, frequent nosebleeds, and sometimes coughs. Due to the deprivation of oxygen, which often occurs with this form of fistula, the individual may develop a cyanosis that is a bluish shade for the skin. In addition, individuals with pulmonary arteriovenous fistula may also be exposed to an increased risk of heart valve infections such as mitral valve stenosis.

There are several diagnostic tests that can be performed for the purpose of diagnosing arteriovenous fistula. During a physical examination, the doctor will listen to individuals L to see if there are any abnormalities such as sounding sound that often occurs in the presence of arteriovenous fistula. If the hum or other abnormality is detected, the individual is usually assigned for further testing. To evaluate blood flow through individual arteries and confirmation of the presence of arteriovenous fistula,

can be madeTesting tests such as angiogram and confirmation of the presence of arteriovenous fistulas can be performed, and the presence of arteriovenous fistulas can be performed and the presence of arteriovenous fistula and confirm the presence of arteriovenous fistula.

In many individuals with AV fistula, treatment consists in monitoring their condition for any changes. Those whose fistula is large may undergo a procedure known as a catheter embolization, which includes the insertion of a stent made of synthetic material to bypass the blood flow around the fistula. Arteriovenous fistulas that cannot be treated by placing a stent may require additional remedial surgical measures. The surgical approach is entirely dependent on the location and size of the fistula and the individual.
