3.2 Investigations
Laboratory work up revealed mild hypernatremia and elevated
creatinine which was gradually subsiding to baseline attributed to
contrast associated nephropathy. He came with abdominal ultrasound
showing renal parenchymal disease and AAA which was confirmed with a
contrast enhanced abdominal CT that showed a thrombosed saccular
infra-renal AAA measuring 5.4 cm in its maximum transverse diameter with
mass effect and stenosis of the left renal artery, small smooth left
kidney with delayed enhancement and excretion secondary to left renal
artery stenosis. Chest x-ray was unremarkable.
