Late open conversion after endovascular abdominal aortic aneurysm repair: experience of three-high volume centers
Abstract
Accumulated endovascular aneurysm repair (EVAR) procedures will increase number of patients requiring conversion to open repair of abdominal aortic aneurysms (AAA). In most cases, patients undergo late open surgical conversion (LOSC), many months, or years, after initial EVAR.
The aim of this study is to analyze results of LOSC after EVAR in elective and urgent setting, including presenting features, surgical techniques, as well as to review the clinical outcomes and their predictors. LOSC seems to be safe and effective procedure when preformed in elective manner.
On the other side, urgent LOSC after EVAR is associated with very high postoperative mortality and morbidity. Endoleak remains the main indication for open conversion.
Further studies are necessary to standardize timing and treatment options for failing EVAR.
