OBJECTIVES: The risk of @entity177 after thoracic endovascular aortic repair is not widely established. The aim of this study was to assess the incidence and risk factors of @entity177 . METHODS: Between 1998 and 2008, 175 consecutive @entity1 underwent 210 procedures at 2 tertiary academic institutions. Similar nephroprotective protocols and intravascular ultrasound were used. Retrospective analysis was performed. Generalized linear model was used to identify factors associated with change in postoperative estimated glomerular filtration rate. RESULTS: Underlying @entity2333 included 103 @entity439 , 72 dissections, 21 transections, and 14 penetrating @entity1066 . Median preoperative estimated glomerular filtration rate was 65 mL    @entity1009 m(-2). Contrast media averaged 108.7    69.8 mL. Median estimated glomerular filtration rates within 48 hours and 30 days were 69 and 67 mL    @entity1009 m(-2), respectively. Rates of @entity810 risk (>25% estimated glomerular filtration rate decrease), @entity810 (>50% estimated glomerular filtration rate decrease), acute kidney function failure (>75% estimated glomerular filtration rate decrease), and hemodialysis were 9.8% (19/193), 1.6% (3/193), 0% (0/193), and 0.5% (1/193), respectively. Rates of @entity8 at 1 month and 6 months were 13.3% (10/75) and 17.7% (6/34), respectively. Risk factors for @entity810 were @entity551 , @entity64 , @entity295 , lengthy procedures, and number of stents; at 1 and 6 months they were increased age, male gender, African American race, @entity6 , chronic @entity358 , smoking, and zone 0 to 1 graft deployment. Obesity was nephroprotective. CONCLUSIONS: Thoracic aortic endograft has a significant rate of @entity8 ; however, it is lower in this cohort than in previous smaller series. Routine use of intravascular ultrasound and reduced contrast may have contributed to lower rates of @entity177 .
