Learning objectives
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.
Background
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...
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,
Radiologist should understand not only which...
Conclusion
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
