CITE THIS ABSTRACT
PURPOSE
to evaluate the advantages of using a robotic tracking system for CT-guided percutaneous vertebral procedures in terms of technical success, procedure's time, perfect centering of the lesion and radiation exposure to the interventional radiology (IR) and patients
METHOD AND MATERIALS
In the period between January 2015 and December 2016 we performed 38 CT-guided percutaneous bone procedures (18 biopsies, 10 crioablations, 10 RFA). 19 procedures (9 biopsies, 5 crioablations, 5 RFA) were performed with "free hand" standard technique, meanwhile 19 procedures (9 biopsies, 5 crioablations, 5 RFA) were performed using a robotic tracking system. The robotic tracking system is able to reconstructs 3D virtual models of the patient's anatomy, starting from CT scans, and allows to follow the positioning of the needle inside the body thanks to a realtime navigation. The final positioning of the needle was confirmed by Fluoro-CT for both procedures.
RESULTS
In the procedures where were used the robotic tracking system Fluoro-CT scans confirmed the correct position of the needle, with a single entry in 12 patients (92%). Technical success for both kind of procedures was 100%. The mean execution time was 16 minutes for the procedures assisted with the robotic system and 25 minutes for the standard procedures. The mean radiation dose for the patients after the first CT-scans used for the visalization of the lesion, was 3.5±1mSv in the standard procedures, and 0.92±0.78mSv in the procedures with the robotic system. The radion dose for the IR was 0.
CONCLUSION
the robot tracking system is an innovative medical device that allows to reduce the procedure's time, the number of CT-scans and consequently, the radiation dose for the patients and for the interventional radiologists. It also allows, following the trajectory of the needle in real time, a rapid and a good centering, even of small lesion, avoiding sensitive structures with a reduction of major complications and technical failure.
CLINICAL RELEVANCE/APPLICATION
The reduction of dose exposure in interventional procedures is been increasing relevance in the last years. The robotic tracking system in our experience showed good results in terms of dose exposure reduction allowing to center even small lesion with an high degree of accuracy
