biostudies-literatureUnknown11(5)van Rijswijk RERecent studies demonstrate that patients with a shrinking abdominal aortic aneurysm (AAA), one-year after endovascular repair (EVAR), have better long-term outcomes than patients with a stable AAA. It is not known what factors determine whether an AAA will shrink or not. In this study, a range of parameters was investigated to identify their use in differentiating patients that will develop a shrinking AAA from those with a stable AAA one-year after EVAR. Hundred-seventy-four patients (67 shrinking AAA, 107 stable AAA) who underwent elective, infrarenal EVAR were enrolled between 2011-2018. Long-term survival was significantly better in patients with a shrinking AAA, compared to those with a stable AAA (p = 0.038). Larger preoperative maximum AAA diameter was associated with an increased lJournal of clinical medicine1394https://www.ebi.ac.uk/biostudies/studies/S-EPMC8910935biostudies-literaturePredictors of Abdominal Aortic Aneurysm Shrinkage after Endovascular Repair.PMC8910935Groot Jebbink Evan Sterkenburg SMvan Rijswijk REStoop NHolewijn SReijnen MMPJfalsePredictors of Abdominal Aortic Aneurysm Shrinkage after Endovascular Repair.Recent studies demonstrate that patients with a shrinking abdominal aortic aneurysm (AAA), one-year after endovascular repair (EVAR), have better long-term outcomes than patients with a stable AAA.
