Great celebrities like Albert Einstein, General Charles de Gaulle and Conway Twitty lost their lives as a consequence of Abdominal Aortic Aneurysm (AAA). AAA was first defined in the 16th century by Vesalius.  Since then, a number of medical interventions were introduced to treat the disease, but all of them proved unsuccessful. Various methods including aortic ligation, cellophane wrapping and aneurysmorraphy were also used in earlier days but they all had poor outcomes.

Effective treatment for aneurysms has just been introduced within past 70-75 years. In 1951, first AAA repair was performed by Charles DuBost using homograft. Later, homografts were replaced by nylon grafts, and then finally by Dacron and Gore-Tex grafts. Silk sutures were replaced by Dacron, polyethylene and PTFT sutures as they have higher tensile strength. The mortality rates for AAAs still remained high till the technique of endoaneurysmorrhaphy was introduced in 1962. Due to the introduction of this technique, the mortality rates dropped from more than 25% to 1.8-5%.

Nowadays, open AAA repair is considered to be a safe treatment option as better grafts have been introduced and preoperative assessment, intraoperative techniques and postoperative care has improved. Recently, techniques of endovascular repair have also been introduced and they further increase the safety of the procedure for high risk individuals.
