Endovascular treatment of the descending thoracic aorta in a patient with a hydatid pseudoaneurysm.

We present a patient affected by systemic hydatidosis with an unusual localization in the thoracic aorta. The pseudoaneurysm, which was treated 8 years ago with conventional surgery, was retreated with an endovascular procedure. The particular evolution of the pathology needed further endovascular intervention.
