Anchoring system-assisted coil tract embolization: a new technique for management of arterial bleeding associated with percutaneous nephrostomy.

Anchoring system-assisted coil tract embolization (AACTE), a new nonvascular treatment technique for massive bleeding associated with percutaneous nephrostomy (PCN), consists of packing the tract with embolization coils, with a balloon catheter used as an anchoring system. After arterial bleeding associated with PCN was successfully treated with AACTE in three patients, no severe complications were noted, and renal function was not affected. AACTE is a potentially useful and safe method for management of vascular complications associated with nephrostomy.
