Cutdown is Associated with Higher 30-day Unplanned Readmissions and Wound Complications than Percutaneous Access for EVAR.

Background: A 2023 Cochrane review showed no difference in bleeding/wound infection complications, short-term mortality and aneurysm exclusion between the percutaneous and cut-down approach for femoral access in endovascular aortic aneurysm repair (EVAR). In contrast, single-center studies have shown bilateral cutdown resulting in higher readmission rates due to higher rates of groin wound infections. Whether 30-day readmission rates vary by type of access during EVAR procedures is unknown.
