Comparable mid-term survival in patients undergoing elective fenestrated endovascular aneurysm repair and endovascular aneurysm repair for abdominal aortic aneurysm

OBJECTIVE To evaluate mid-term survival in patients undergoing elective fenestrated endovascular aneurysm repair and standard endovascular aneurysm repair for abdominal aortic aneurysm. METHODS Consecutive patients treated from 2007 to 2011 with elective fenestrated endovascular aneurysm repair (n = 81) and endovascular aneurysm repair (n = 201) were evaluated concerning age, cardiovascular medication, comorbidities, and mid-term mortality. RESULTS Patients in the elective fenestrated endovascular aneurysm repair group were younger than the endovascular aneurysm repair group (p = 0.006). In comparison with the endovascular aneurysm repair group, a lower proportion of patients in the elective fenestrated endovascular aneurysm repair group had diabetes (p = 0.013) and anemia (p = 0.003), and a higher proportion had arterial hypertension (p = 0.009). When entering age, endovascular aneurysm repair or fenestrated endovascular aneurysm repair operation, diabetes, anemia, and hypertension in a Cox regression model, only age (hazard ratio: 1.07; 95% confidence interval: 1.03-1.11; p < 0.001) was a risk factor for mid-term mortality. CONCLUSION Careful patient selection and medical optimization resulted in comparable mid-term survival in patients undergoing elective fenestrated endovascular aneurysm repair and endovascular aneurysm repair.
