An unusual renal colic during trans-arterial embolization after trauma and its multidisciplinary management

Selective embolization is the treatment of choice for traumatic renal pseudoaneurysm (PSA) in stable patients. N-Butyl-2-cyanoacrilate (NBCA) is an embolic agent frequently used to embolize peripheral lesions. N-Butyl-2-cyanoacrilate is one of the most widely used embolic materials because it is easy to prepare, it acts quickly and is highly cost-effective. Its use, however, requires a learning curve before becoming confident and being able to handle it safely. We describe a case of embolization of a renal traumatic PSA without clear pre-procedural CT-evidence of artero-calyx fistula in which the migration of NBCA in the renal pelvis occurred during the procedure. We report the successful multidisciplinary management of this complication.
