Results and discussion
The highest reference levels obtained correspond to therapeutic procedures such as hepatic chemoembolization (163 Gycm2) or cerebral aneurysm embolization (48 Gycm2).
The lowest levels, as expected, correspond to diagnostic procedures such as lower extremity arteriography (18 Gycm2) and biliary drainage (15 Gycm2), and to procedures such as drainage catheter placement (1.1 Gycm2) and central venous catheter replacement (0.9 Gycm2). Table 1 contains mean, median and standard deviation for KAP at different procedures, as well as the fluoroscopy time.
Preliminary dose analysis shows that highest dose values correspond to procedures with higher complexity and consequently longer fluoroscopy time, such as hepatic chemoembolization or cerebral aneurysm embolization.
Lowest doses correspond to diagnostic procedures like lower extremity arteriography, biliary drainage, drainage catheter placement and central venous catheter replacement because of its reduced complexity.
Updated DRLs in our vascular section are shown in figure 1, and regular revision of these levels will allow for optimisation of procedures, allowing to reduce both patients and staff doses.
Further efforts have to be made in order to add new different procedures to the local DRL catalog.
