[Selective transcatheter embolization for renal artery aneurysms: report of three cases].
Selective transcatheter embolization using an interlocking detachable coil (IDC) or detachable balloon was performed in three patients with renal artery aneurysms. All aneurysms were of the saccular type, located on segmental branches of the renal artery. After the embolization procedures, the levels of LDH, GOT, WBC and the body temperature were transitionally elevated in all patients. Complete occlusion of the aneurysms were achieved in all cases. Good clinical results were achieved in two of these patients without any renal dysfunction. However, local infarction of ipsilateral renal parenchyma occurred in one patient immediately after the embolization and a Tc-99m-DMSA renal scintigraphy study suggested renal dysfunction after infarction, and the level of serum renin activity was slightly elevated. Selective transcatheter embolization may constitute an acceptable therapeutic approach for renal artery aneurysms because beside avoiding surgery, it has a low risk of complications.
