| Popis: | This study was performed to compare the rate of morphological (renal infarction and/or ischaemic lesions) and functional renal complications after the suprarenal and infrarenal fixation of aortic stent-grafts for endovascular abdominal aortic aneurysm repair (EVAR).We retrospectively reviewed all followup computed tomography (CT) angiograms (obtained at 1, 6 and 12 months and yearly thereafter) and laboratory data pertaining to 102 patients who underwent suprarenal (60 patients, group A) or infrarenal (42 patients, group B) placement of aortic stent-grafts. The groups were compared in terms of complications affecting kidney function (creatinine clearance) and morphology (renal artery steno-occlusions, morphological and structural parenchymal changes), and pre- and postprocedural arterial pressure (AP).Analysis of patient demographics revealed no statistically significant difference between the two groups. The proximal neck was shorter in group A (2.14 cm+/-0.84 cm) than in group B (3.41 cm+/-1.21 cm). Creatinine clearance (CrCl) decreased in both groups (group A: from 64.24 ml/min to 60.66 ml/min; group B: from 72.41 ml/min to 68.73 ml/min) without any significant difference in terms of changes in renal function (CrCl variation: -8.75% vs. -6.4%) or morphology (post-EVAR stenosis: 2.6% vs. 0%; progression of existing steno-occlusive lesions: 1% vs. 0%; ischaemic lesions: 3.2% vs. 0%), or in AP.In our experience, the use of abdominal endografts with suprarenal fixation did not lead to any significant increase in morphological and/or functional renal complications compared with those with infrarenal fixation. |
