A Multicenter Survey of Endovascular Theatre Equipment and Radiation Exposure in France during Iliac Procedures

{Background: The aim of this study is to evaluate radiation exposure, endovascular theatre equipment, and practices in France during iliac angioplasty. Methods: A prospective observational study was performed among vascular surgeons who attended a half day of radiation safety training in 2012 and 2015 and had to collect data on 3 patients undergoing iliac procedure. In 2012, 330 surgeons performed 899 procedures, compared with 114 surgeons and 338 procedures in 2015. Due to exclusions, 653 and 306 procedures were analyzed in 2012 and 2015, respectively. Endovascular environment, practices, anatomical characteristics, and radiation parameters were collected, analyzed, and compared generally and between the 2 groups. Results: Endovascular theatre equipment significantly improved over the 3 years: mobile flat-panel detector (1.1% vs. 5.9%), hybrid rooms (1.5% vs. 14.7%), and dedicated radiology tables (37.2% vs. 51.2%). Lesion's classification (Trans-Atlantic Society Consensus) was similar between groups but procedure complexity increased overtime: more than one stent implanted (32.3% vs. 41%, P < 0.01), cross over (11.5% vs. 16%, P < 0.05), and kissing procedures (19.3% vs. 24.2%
