Renal infarction with Gianturco wool coils. Use in the management of massive proteinuria.

A mechanical device was successfully used in therapeutic renal artery occlusion in a patient with renal amyloidosis and massive proteinuria (25 g/day). The serum albumin level increased from 1.8 to 3.4 g/dL after cessation of proteinuria. There has been no evidence of peripheral embolization, hypertension, or infection of the infarcted kidney for the past 20 months following the procedure.
