Background: Abdominal aortic aneurysms (AAA) are often identified incidentally on imaging studies. Patients and/or providers are frequently unaware of these AAA and the need for long-term follow-up. We sought to evaluate the outcome of a nurse-navigator-run AAA program that uses a natural language processing (NLP) algorithm applied to the electronic medical record (EMR) to identify patients with imaging report-identified AAA not being followed actively.

- Researchers studied the risks of large abdominal aortic aneurysms (AAAs) in older patients who either didn’t have surgery or had it delayed.
- They looked at data from a health registry between 2003 and 2020, focusing on patients who had large AAAs (over 5 cm) and noted details like if and when they received treatment.
- Results showed that many patients did not have surgery right away and some of them experienced serious issues, like ruptures, showing that bigger AAAs can be very dangerous if not treated quickly.
Article Synopsis
- The study looked at using a computer program (NLP) to find and measure abdominal aortic aneurysms (AAAs) in a lot of medical reports.
- They reviewed 18,000 imaging reports and found that almost half showed AAAs were present.
- The NLP tool did a good job, working almost as well as human experts in detecting AAAs and measuring how big they were.
Objective: Endovascular aneurysm repair (EVAR) has become the preferred approach to abdominal aortic aneurysm (AAA) because of lower early morbidity and mortality than open repair. However, the ability of EVAR to prevent long-term aneurysm-related mortality (ARM) has been questioned in light of recent trial data. We have updated our long-term EVAR experience in a large multicenter registry to further examine this issue.

Methods: Between 2000 and 2010, 1736 patients underwent EVAR, and we recorded the incidence of T2L.
Objective: Prior reports have suggested unfavorable outcomes after endovascular aortic aneurysm repair (EVAR) performed outside of the recommended instructions for use (IFU) guidelines. We report our long-term EVAR experience in a large multicenter registry with regard to adherence to IFU guidelines.
Methods: Between 2000 and 2010, 489 of 1736 patients who underwent EVAR had preoperative anatomic measurements obtained from the M2S, Inc, imaging database (West Lebanon, NH).
Objective: Rupture after abdominal endovascular aortic aneurysm repair (EVAR) is a function of graft maintenance of the seal and fixation. We describe our 10-year experience with rupture after EVAR.
Methods: From 2000 to 2010, 1736 patients with abdominal aortic aneurysm (AAA) from 17 medical centers underwent EVAR in a large, regional integrated health care system.
Objective: To assess outcomes after endovascular abdominal aortic aneurysm repair (EVAR) in an integrated health care system.
Methods: Between 2000 and 2010, 1736 patients underwent EVAR at 17 centers. Demographic data, comorbidities, and outcomes of interest were collected.
