The Third and Fourth Dimensions of EVAR

In an intuitive retrospective study of 404 endovascular aneurysm repair (EVAR) patients, Oliveira-Pinto et  al.1 investigated the relationship between pre-operative abdominal aortic aneurysm (AAA) sac luminal volume (i.e. sac volume minus thrombus volume) and aneurysm related morbidity, secondary interventions, and mortality. The authors found that patients in the highest luminal volume quartile had sig nificantly wider, shorter, and more angulated proximal necks. Additionally, these high luminal volume AAAs demonstrated a significantly increased five year risk of AAA related complications which remained robust even after adjusting for endograft instructions for use compliance.
