Utility of Noninvasive Aneurysm Sac Pressure Measurement During and After Endovascular Abdominal Aortic Aneurysm Repair

An intraoperative decrease in PP and PPR in the range of approximately 70% after EVAR was associated with successful aneurysm exclusion. Noninvasive sensors can provide useful ancillary information in confirming technical success intraoperatively. During follow-up, an increase in sensor pressure recordings may be suggestive of clinically significant endoleak; however, further research is necessary.
