Outpatient Percutaneous Endovascular Abdominal Aortic Aneurysm Repair: A Single-Center Experience
Evaluate the safety of outpatient percutaneous endovascular abdominal aortic repair (PEVAR) when compared to inpatient PEVAR.
Take away point
Outpatient PEVARs are a safe option with decreased procedure time.

Retrospective review of all elective outpatient or inpatient PEVARs for infrarenal AAA repair between January 2012 and June 2019.
No reported funding.
Academic setting, Chang Gung Memorial Hospital, Taoyuan, Taiwan
Patients who had asymptomatic AAA with an aneurysm sac diameter greater than 5 cm with anatomy compatible with standard off-the-shelf devices and with an available caregiver at home were selected for the outpatient group. All outpatients and most inpatients received total intravenous anesthesia (TIVA) with propofol and fentanyl, an important factor in reducing complications.
The Society of Interventional Radiology’s classification system was used to grade complications. The primary outcome measure included mortality, complications, length of stay, and readmissions. No outpatient mortalities were documented and 4 inpatient mortalities occurred. There were no statistically significant differences in complications between the two groups. No statistically significant difference in length of stay among outpatients that were admitted unexpectedly and inpatients.
The secondary outcome was operative time. Mean operative times only for outpatients were significantly shorter, 150 minutes +/- 32 vs 172 minutes +/- 53 (P < 0.01), without inclusion of any adjunct procedures. When adjunct procedures were required, no statistically significant difference was observed between the outpatient and inpatient groups.
