How is Aortoenteric fistula treated?
Several surgical approaches are used for the treatment of secondary aortoenteric fistula. But the most widely accepted technique involves the debridement of the infected tissues, repair of the fistula, complete removal of the graft, and revascularization.
What causes Aortoenteric fistula?
Primary aortoenteric fistula (PAEF) — Primary aortoenteric fistula (PAEF) arises de novo between the aorta and the gastrointestinal tract. Causes of PAEF include aneurysm (most common), foreign body, tumor, radiation therapy and infection (eg, tuberculosis, syphilis) [5-7].
How is Aortoenteric fistula diagnosed?
Symptomatology can be varied but most often includes signs of infection and of gastrointestinal bleeding. Esophagogastroduodenoscopy (EGD) and computed tomography (CT) scans are the most useful tests to diagnose AEF. Treatment almost always requires excision of the infected graft and revascularization.
Which of the following is the most common location of Aortoenteric fistula formation?
The third or fourth portion of the duodenum is the most common site for aortoenteric fistulas, followed by the jejunum and ileum.
What is an Aortocaval fistula?
Aortocaval fistula (ACF) is a rare complication of abdominal aortic aneurysm, which erodes into the wall of the inferior vena cava, resulting in the formation of a fistula. ACF presents with various inconsistent symptoms and signs. ACF can be a diagnostic dilemma if not suspected and it is lethal if left untreated.
What is an aortic fistula?
A fistula is an abnormal, tubelike connection between two structures inside the body. When the connection is between the aorta and a loop of bowel that is near the aorta it is known as an aortoenteric fistula (AEF).
Where is the Aortocaval region?
Aortocaval compression syndrome is compression of the abdominal aorta and inferior vena cava by the gravid uterus when a pregnant woman lies on her back, i.e. in the supine position.
What is Aortocaval compression?
Aortocaval compression (ACC) occurs when the gravid uterus compresses the maternal abdominal aorta and inferior vena cava (IVC). Compression of the IVC impedes venous return which decreases cardiac output (CO), and compression of the aorta may reduce uteroplacental perfusion which may result in fetal acidosis.
What is Aortobifemoral bypass?
An aortobifemoral bypass is surgery to redirect blood around narrowed or blocked blood vessels in your belly or groin. The surgery is done to increase blood flow to the legs. This may relieve symptoms such as leg pain, numbness, and cramping.
What does Aortocaval mean?
How is Aortocaval compression prevented?
Compression of the IVC impedes venous return which decreases cardiac output (CO), and compression of the aorta may reduce uteroplacental perfusion which may result in fetal acidosis. It is recommended that the ACC be avoided by applying lateral uterine displacement.
