Iatrogenic migration of inferior vena cava (IVC) filters is a potentially life-threatening complication that can arise during blind insertion of central venous catheters when the guide wire becomes entangled with the filter. In this study, we reviewed the occurrence of iatrogenic migration of IVC filters in the literature and assessed methods for preventing this complication. ⋯ Iatrogenic migration of an IVC filter is an uncommon complication related to wire/filter entrapment. This complication can be prevented with knowledge of the patient's history, use of proper techniques when placing a central venous catheter, identification of wire entrapment at an early stage, and use of an appropriate technique to disengage an entrapped wire.

Percutaneous endovascular abdominal aortic aneurysm repair (PEVAR) has been associated with fewer groin wound complications and shorter operative times, but same-day discharge (SDD) has not been reported. The goal of our article is to assess the feasibility and safety of ambulatory PEVAR and identify patient characteristics that are eligible for this approach. ⋯ Ambulatory PEVAR was found to be feasible and safe in one-third of patients undergoing elective EVAR who did not have excessive medical risk, had good functional capacity, and underwent an uneventful procedure. The impact of SDD on cost-effectiveness needs to be further assessed and may not be feasible in hospitals reimbursed based on admission status.

Comparative Study
Comparison of outcomes following endovascular repair of abdominal aortic aneurysms based on size threshold.
Size threshold for operative repair of abdominal aortic aneurysms (AAAs) has been determined based on risks and outcomes of open repair vs surveillance. The influence of endovascular aneurysm repair (EVAR) on this threshold is less established. The purpose of this study is to determine whether long-term outcomes following EVAR are affected by maximum diameter at the time of treatment. ⋯ EVAR for small AAAs shows improved long-term outcomes than for age-matched patients with larger aneurysms.
