INTRODUCTION: We report our experience with the superselective embolization of @entity1317 . We used new coaxial catheters and new microcoils to assess their technical features and efficacy. MATERIALS AND METHODS: Diagnostic angiography by catheterization of the main renal artery was performed in 7 @entity1 with suspected @entity8 to detect injury presence and site. After super-selective catheterization of the feeding arteries with a coaxial catheter (Tracker 18), we performed embolization with @entity902 microcoils inserted using a coil pusher. The procedure efficacy was assessed at angiography and by comparing serum hemoglobin and hematocrit levels before and after embolization; posttreatment renal function was also studied. RESULTS: Selective embolization permitted complete occlusion of the arteries feeding the @entity1317 in all @entity1 , preserving as much parenchyma as possible. Hemoglobin and hematocrit levels were improved or unchanged after the maneuver (average hemoglobin level before embolization: 9.01 mg/dl versus 9.95 mg/dl after embolization; average hematocrit level before embolization: 27.3% versus 30.06% after embolization). We had no difficulty during microcoil insertion and the coaxial catheter was always stable. CONCLUSION: Superselective embolization of @entity1317 is an effective and definitive treatment. We recommend it in the @entity1 with @entity8 due to @entity1317 after percutaneous diagnostic or therapeutic procedures.
