Treatments will be different depending on the type of aneurysm (location, shape, size ...).
Some aneurysms can be treated endovascularly with interventional radiology: this is a catheter that is mounted from the easily accessible femoral artery (main arterial trunk of the lower limb that is accessible at the level of the crease of the groin) counter to the seat of an aortic aneurysm for example.
The inside of the vessel and the aneurysm are visualized by medical imaging thanks to the injection of a contrast product by the probe .... The aneurysm can thus be treated visually via the inside of the artery with prostheses, balloons ... that are mounted by the probe.
Other aneurysms require open surgery and treatment of the lesion via the outside of the artery. In case of aneurism of the aorta, if the haemorrhage is not extensive, an emergency surgery can save the patient. Aneurysms of the abdominal aorta are surgically easier to access than those of the thoracic aorta.
It is obvious that to prevent the risks of aneurism installation and its development will avoid very serious complications: to avoid the atherosclerosis and the deposit of the plates of atheromas in the arteries by a correct hygiene of life: daily food hygiene, activity physics, fight against tobacco, fight against high blood pressure, fight against obesity, fight against diabetes, fight against dyslipidemias (hypercholesterolemia, hypertriglycidemia).
When an aneurysm is installed and tested, it must be closely monitored, possibly removed if it is accessible, and the benefit versus risk is worth the cost.
