Should the threshold for abdominal aortic aneurysm repair be loosened to 50 mm diameter compared to the traditional 55 mm threshold?
Should the threshold for abdominal aortic aneurysm repair be loosened to 50 mm diameter compared to the traditional 55 mm threshold?
A looser threshold of 50 mm diameter for abdominal aortic aneurysm repair may be considered over the traditional 55 mm threshold, particularly in vulnerable populations.
An abdominal aortic aneurysm (AAA) will progressively grow until rupture if a repair is not performed in time, either by open surgery or endovascular techniques. Although the risk of AAA rupture increases with its diameter, there is still a lack of any accurate marker to predict the AAA growth rate or the rupture risk. However, early repair might not be a good approach as the morbidity and mortality associated with both techniques remain non-negligible. A looser and simple threshold of 50 mm diameter could replace the traditional 55 mm threshold for AAA repair, especially in a vulnerable population.
