Endovascular repair of abdominal AAA.
The superior extent of the graft extends to the origin the renal arteries. The renal arteries demonstrate ostial calcified atherosclerosis but are patent. No renal infarcts.
The graft extends into the common iliac vessels bilaterally.
There is a endoleak seen adjacent to the superior extent. The endoleak is present in the arterial phase imaging and washes out in the portal venous phase.
The native aortic sac measures 5.1cm in diameter (unchanged), filled with thrombus and locules of gas.
Conclusion:
The appearances are consistent with a type 1 endoleak (between the graft and the native aortic sac).
