What is an Aortocaval fistula?

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 physiologic change might you see with a large Aortocaval fistula?

The most obvious physiologic change concomitant with the forma- tion of an AV fistula is the severalfold increase in blood flow, especially during diastole.

What is abdominal aorta imaging?

An abdominal aortic ultrasound or abdominal aortic duplex is an exam that can help your interventional radiologist evaluate the aorta, which is the main blood vessel that supplies the body’s organs. This allows us to look for any abnormalities such as abdominal aortic aneurysm or aortic dissection.

What is the Aortocaval region?

aortocaval (not comparable) (anatomy) relating to the aorta and the vena cava quotations ▼

What is a para aortic lymph nodes?

Introduction. The para-aortic lymph nodes (PANs) are located around the abdominal aorta and inferior vena cava and are the regional lymph nodes of the intraperitoneal organs.

What is inferior vena cava?

The inferior vena cava is a large, valveless, venous trunk that receives blood from the legs, the back, and the walls and contents of the abdomen and pelvis.

Does abdominal CT scan show aorta?

Abdominal CT scan. This painless test uses X-rays to create cross-sectional images of the structures inside the belly area. It’s used to create clear images of the aorta. An abdominal CT scan can also detect the size and shape of an aneurysm.

What is USG abdomen test?

Abdominal ultrasound is a type of imaging test. It is used to look at organs in the abdomen, including the liver, gallbladder, spleen, pancreas, and kidneys. The blood vessels that lead to some of these organs, such as the inferior vena cava and aorta, can also be examined with ultrasound.

What type of CT is used for abdominal aortic aneurysm?

Dual-slice helical CT correlates well with surgical findings in measuring the proximal and distal extent of the aneurysm. CT and CT angiography are not only less invasive than conventional aortography but also allow for more rapid scanning times and evaluation of the rest of the abdomen.

Can CT scan detect abdominal aortic aneurysm?

What is RPLND surgery?

Retroperitoneal lymph node dissection, commonly referred to as RPLND, is a procedure to remove abdominal lymph nodes to treat testicular cancer, as well as help establish its exact stage. It is usually performed using an incision that extends from just below the breastbone (sternum) to just below the navel.
