Aims and objectives
Pediatric patients have a higher average risk of developing cancer compared with adults receiving the same dose.
Children are more sensitive to radiation than adults and have a longer life after exposure during which they can manifest the deleterious effects of radiation  . In fact,
the longer life expectancy in children allows more time for any harmful effects of radiation to manifest,
and developing organs and tissues are more sensitive to the effects of radiation  .
Methods and materials
308 interventional hepatobiliary procedures were performed in our transplant centre over a 7 years period including: 17 transarterial procedures [chemoembolization (TACE),
hepatic arteriography); 3 shunt closure (spleno-renal shunt,
spontaneous porto-systemic shunt,
porto-caval shunt); 38 percutaneous transhepatic procedures (transhepatic portography,
percutaneous portal vein angioplasty,
percutaneous portal vein angioplasty with stenting); 177 biliary procedures [Percutaneous transhepatic...
A total of 94 patients were included in our retrospective study; age varying between 1 month and 17 years and Bodysurface area (BSA [per DuBois & DuBois]) range was 0.21-1.77. Data from 308 procedures were analyzed grouping them of same or similar approach. These included: 17 transarterial procedures (6 TACE,
11 hepatic arteriography); 3 shunt closure (1 spleno-renal shunt,
1 spontaneous porto-systemic shunt,
1 porto-caval shunt); 38 percutaneous transhepatic procedures (14 transhepatic...
This study summarizes the radiation exposure of pediatric patients in a wide variety of hepatobiliary procedures with special attention to optimization of imaging parameters.
However we cannot compare DAP each other due to the difference in the number of procedures and in the variety of patients’ BSA among the procedures performed. In view of this,
our preliminary data also show that total fluoroscopy time is a poor predictor ofpatientdoseininterventionalradiology and it is not possible to...
