[Endovascular stent graft support exclusion of an infrarenal aortic aneurysm using gadolinium as contrast medium in kidney insufficiency].
METHODS
A 64-year-old obese man with radiocontrast-induced nephropathy, which required temporary hemodialysis, was referred for treatment of an infrarenal abdominal aortic aneurysm detected incidentally. Comorbidities were obesity (BMI 44.1), non-insulin dependent diabetes mellitus, arterial hypertension, COPD, and renal failure with decompensated retention.


METHODS
MRI demonstrated a 6.1 cm diameter infrarenal partially thrombosed aortic aneurysm which extended to the aortic bifurcation. Its morphology was favourable for endovascular treatment.


METHODS
An aortobiiliac stent graft was inserted after bilateral arterial femoral cut-down. As a contrast agent we administered 0.5 molar gadoteridol solution only. The total volume used was 90 ml (0.375 mmol/kg body weight). The aneurysm was completely excluded. No further signs of renal deterioration occurred.


CONCLUSIONS
Non-nephrotoxic gadolinium-containing contrast media allow minimal invasive exclusion of infrarenal aortic aneurysms with use of stent grafts in patients in whom conventional iodinated x-ray contrast agents are contraindicated.
