Pacemaker implants are associated with a high cumulative exposure of the operators to radiation. Standard radiation protection with lead aprons is incomplete and the cause of spine disorders. A radiation protection cabin offers complete protection by surrounding the operator, without requiring a lead apron.
METHOD & RESULTS:
60 patients undergoing implantations of permanent pacemakers or ICD have been randomly assigned, divided in 2 groups :
- Control group : 0.5 mm lead-equivalent apron (n=30)
- Radiation protection group : n=30
Radiation exposure was measured using personal electronic dosimeters placed on thorax, back, and head of the operator.
The cabins are covered with a dedicated sterile field to preserve rigorous aseptic conditions.
C-arm used ALLURAXper®FD10 (Philips, Eindhoven, The Nedtherlands) at low doses.
The characteristics of the 2 study groups, including age, sex distribution, treatment indications, devices and number of leads implanted, and percutaneous access (cephalic or subclavian) were similar
This randomized study showed that the use of a radiation protection cabin during implantation of single or dual chamber cardiac devices was associated with neither longer procedures or fluoroscopic exposure, nor a higher rate of complications.
The recorded doses are the following :
- The mean radiation dose to the head, normalized for fluoroscopy duration, was significantly lower in the cabin (0.040±0.032 μSv/min) than in the control group (1.138±0.560 μSv/min)
- The radiation dose to the thorax (0.043±0.027) vs (0.041±0.040 μSV/min) ; the back (0.038±0.029) vs (0.033±0.018 μSv/min) in the cabin vs control group were similar
The use of a radiation protection cabin markedly decreased the exposure of the operator to radiation, and eliminated the need to wear a lead apron, without increasing the procedural time or complication rate during implantation of pacemaker and ICD.
