PURPOSE: To evaluate the efficacy of transcatheter arterial embolization(TAE) in children with blunt splenicinjury. MATERIALS AND METHODS: The results of transcatheter splenic arterial embolization in nine children whosuffered splenic injury after blunt abdominal trauma were retrospectively studied. This injury was demonstrated byCT, and the findings were evaluated according to the classification of Mirvis et al. ; two patients were grade 3and seven were grade 4. All were carefully observed in intensive care before embolization. TAE was performed if apatient satisfied the following criteria : (1) transfusion and/or fluid replacement required to maintainhemodynamic stability ; or (2) rapid Hb/Hct decrease ; or (3) both. Splenic function was subsequently estimatedaccording to the results of 99mTc-sulfur colloid scintigraphy and/or CT scanning. RESULT: TAE was suscessful inall nine children. Two were embolized with a coil only, three with gelfoam, and four with gelfoam and a coil.Seven were embolized in the main trunk of the splenic artery and others in both the main trunk and its branches.Splenic function was preserved in all nine children, during follow-up, none suffered rebleeding. CONCLUSION: TAEof the splenic artery can be a safe and effective nonsurgical approach to the management of blunt splenic injuryin children, and can preserve splenic function.

In the management of carotid cavernous fistula, detachable balloon has become the treatment of choice.However, technical difficulties are not uncommon, and transarterial balloon embolization fail in 5% to 10% ofcases. Failure occurs because in some patients, the fistula orifice may be too small to allow entry. Using atracker catheter system with Guglielmi detachable coils, we achieved successful transarterial occlusion of acarotid cavernous fistula with a small fistula.
