Key result
Endovascular repair of small abdominal aortic aneurysms (4.0-4.9 cm) demonstrated a 9.1% perioperative complication rate and 0.8% 30-day mortality, with 84% overall survival at 5 years.

What are the outcomes of endovascular repair for small abdominal aortic aneurysms (4.0-4.9 cm)?
Endovascular repair of small abdominal aortic aneurysms (4.0-4.9 cm) is associated with low perioperative morbidity and mortality, suggesting the treatment threshold could potentially be reduced to 4 cm in selected patients.
Low perioperative risks in observational data; leaves open whether repair threshold should shift without RCTs.
The outcomes of endovascular repair for small abdominal aortic aneurysm (4.0-4.9 cm) is reported. All patients undergoing endovascular abdominal aortic aneurysm repair between 2000 and 2006 with maximal diameter 4.0 to 4.9 cm form the small aneurysm study cohort. Data were analyzed retrospectively and life-table methods were used. Of 743 endovascular repairs, 132 (17.8%) were performed for small abdominal aortic aneurysm. Perioperative complication rate was 9.1%. Freedom from aneurysm expansion was 96% at 1 year, 86% at 3 years, and 77% at 5 years. Overall survival was 98%, 93%, and 84% at 1, 3, and 5 years, respectively. Perioperative 30-day mortality was 0.8% with an aneurysm-related mortality of 1.5% at 5 years. There were no deaths from delayed aneurysm rupture. Endovascular repair of small abdominal aortic aneurysm is associated with low perioperative morbidity and mortality compared with published results for open repair, and treatment threshold can be reduced to 4 cm in selected patients.

LeCroy et al. (2008) conducted a cohort in Small abdominal aortic aneurysm (4.0-4.9 cm) (n=132). Endovascular repair vs. Published results for open repair was evaluated on Perioperative 30-day mortality. Endovascular repair of small abdominal aortic aneurysms (4.0-4.9 cm) demonstrated a 9.1% perioperative complication rate and 0.8% 30-day mortality, with 84% overall survival at 5 years.
