Abstract
Percutaneous renal biopsy (PRB) is an important procedure in the diagnostic and prognostic evaluation of renal disorders. Despite the relative simplicity, it can be a possible cause of iatrogenic renovascular injury. We describe two cases of iatrogenic pseudoaneurysm, a major post-biopsy complication, in two pediatric patients with persistent micro- and macro-hematuria, promptly diagnosed using color Doppler ultrasound, confirmed with renal arteriography and treated with embolization.
Sommario
La biopsia renale percutanea (BRP) è una procedura fondamentale nella valutazione diagnostica e prognostica delle patologie renali. Nonostante la relativa semplicità, può esser causa di danno renovascolare iatrogeno. Descriviamo due casi di pseudoaneurisma iatrogeno, una complicanza maggiore post-bioptica, in due pazienti pediatrici con micro e macroematuria persistente, tempestivamente diagnosticata con eco-color Doppler, confermata con arteriografia renale e trattata mediante embolizzazione.
