Although the exact causes are currently unknown, doctors believe that the onset of an abdominal aneurysm is favored by several factors, such as hypertension, aging, cigarette smoking, etc.
Symptoms, when present, consist of a strange throbbing sensation in the navel, accompanied by persistent abdominal pain and lower back pain.
For a precise diagnosis, in addition to the physical examination, an abdominal ultrasound, a CT scan and / or a nuclear magnetic resonance are usually needed.
The therapy involves surgery, which is generally practiced only in the case of large aneurysms.
