BACKGROUND: We evaluated mechanisms of failure and outcome of secondary surgical interventions after @entity1514 endovascular aortic repair (TEVAR). METHODS: Between 1996 and 2009, 421 @entity1 underwent TEVAR for the following indications: @entity731 , type B dissections, penetrating @entity1066 and @entity131 . RESULTS: Twenty-one @entity1 underwent secondary surgical interventions. Indications were type I endoleak formation, retrograde type A dissection, distal @entity439 formation as well as infection. Retrospectively, by analysing referral computed tomography scans and by current knowledge, failure could have been foreseen in 72% of @entity1 . Median interval to secondary surgical intervention was 24 months (IQR 8-40). Sixteen @entity1 underwent @entity1514 or thoracoabdominal repair and five @entity1 underwent ascending and hemiarch replacement. In-hospital mortality was 19%. Cause of death was @entity177 in all cases. CONCLUSIONS: The need for secondary surgical intervention after TEVAR is low but carries risk. By analysing mechanisms of failure, the majority of these events could have been avoided by a more strict indication. Thereby, further critical evaluation and respecting limitations of TEVAR will help to reduce the need for these operations.
