SCI following thoracic and thoracoabdominal aortic endovascular intervention is associated with the proportion of aorta covered. The degree of risk varies between different types of procedure and this should be carefully considered in both selection and consenting of patients.

In selected patients, fenestrated and branched stents appear to be a safe and effective alternative to surgery for juxtarenal and thoracoabdominal aneurysms. The complication and mortality rates are low. The long-term durability of this procedure, however, needs to be proven.

The results of the latest series show that open surgery is still required in many cases. The introduction of endovascular techniques in the exclusion of mycotic aneurysms can be accomplished with acceptable results, and endovascular treatment has increased the therapeutic options for a difficult condition.
