NEW YORK – A clever strategy to evaluate long term outcomes in patients undergoing endovascular abdominal aortic aneurysm repair identified a 20% rate of reintervention, according to data presented at a symposium on vascular and endovascular issues sponsored by the Cleveland Clinic Foundation by Philip P. Goodney, MD.
In this video interview with Dr. Goodney, an associate professor of vascular surgery at Geisel School of Medicine at Dartmouth, Hanover, N.H., he explains how Medicare data were employed to track patients long term, even when they had moved to other hospital systems.
The main message from the long-term follow-up is that there is a persistent risk of recurrence and need for reintervention, according to Dr. Goodney. The hypothesis was that there would be an early risk of failure, followed by a diminishing need for reintervention over time, but this was not what was observed.Rather, the findings suggest that the rate of reinterventions was relatively steady over the course of follow-up, suggesting that patients should be informed of a persistent risk. However, Dr. Goodney reports that age was not a predictor of reintervention, so that older patients were at no greater risk.
