[Iatrogenic renal perforation during percutaneous angioplasty]

Percutaneous transluminal angioplasty is recommended as the first choice of therapy for renal artery stenosis. However, morbidity and mortality are significant. Among hemorrhagic complications, renal perforation is unusual. A case is reported, caused by the use of an angled hydrophilic guidewire, in which the diagnosis has been made by computed tomography angiography with typically perirenal hematoma and extravasation of contrast material corresponding to the perforation. This complication has been successfully treated with conservative measures.
