Feasibility and Outcomes of Endovascular Aneurysm Repairs (EVARs) Without Arterial Line Monitoring

Endovascular Aortic Aneurysm Repairs (EVARs) are typically performed with arterial line monitoring, however our institution has successfully omitted this practice in select cases without complications or patient safety concerns. To investigate this further, our planned study will compare patients undergoing EVAR with and without arterial line monitoring. Data will be collected on pre-operative characteristics (patient age, sex, comorbidities), intraoperative details (procedural time, need for emergent intra-operative arterial monitoring or blood draws), and postoperative outcomes (complications, time in post-operative recovery unit). Operating room staff satisfaction and acceptability will be measured using a survey developed by our team. The findings from this study hold promise for improvement the treatment of aortic aneurysms, as well as enhancing patient safety and experience.
