The aim of this paper is to evaluate the diagnostic approach in case of aorto-digestive fistula (FAD).
We describe which are the most common causes of this rare condition,
explaining common imaging details which can guide the radiologist in the correct diagnosis.
FAD represents a wide range of rare conditions that could be fatal in short time.
As a consequence it is difficult to have a large and direct experience.
FAD represent a clinical condition with high mortality rate and short-term morbidity with a very short intervals between diagnosis and therapy.
First of all,
the radiologist has to recognize if FAD is a primary condition or not.
In the first case,
FAD is caused by a direct and spontaneous rupture of aorta in a digestive tract in absence of...
Findings and procedure details
Despite being an emergency,
in the 75% of cases FAD does not have a clinically evident beginning.
As a consequence,
the correct use of imaging is basic not only from a diagnostical point of view,
but also for clinical management. Melena and hematemesis could be very important clinical signs which can guide the radiologist to the differential diagnosis.
CT-angiography is the gold standard in case of FAD with a sensibility of 94% and specificity of 85%. First of all,
FAD are rare conditions which represent the 0,5-2% of digestive bleeding.
Mortality of 100% if not treated. A correct diagnosis could save the Patient,
guiding surgeon or Interventional radiologist to the correct management of the situation. EGDS and Angio-CT gold standard for diagnosis Necessary multidisciplinary team
