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 absence of trauma or surgery.
In case of “secondary FAD”,
it could be the consequence of infections,
trauma or surgery.
According with FAD localization,
the radiologist has to recognize if this condition starts from the digestive system or from the vascular one.
> 80% starts from vascular system:
•aneurysm rupture
•prosthetic infections
•penetrating ulcers
•giant cell arteritis
< 20% starts from intestinal lesions:
•advanced neoplasms
• lymphatic metastases
•foreign bodies
•traumas
