3D-printed face protective shield in interventional radiology: Evaluation of an immediate solution in the era of COVID-19 pandemic

The purpose of this study was to report the clinical evaluation of a 3D-printed protective face shield designed to protect interventional radiologists from droplet transmission of the SARS-Cov-2. A protective face shield consisting in a standard transparent polymerizing vinyl chloride (PVC) sheet was built using commercially available 3D printers. The 3D-printed face shield was evaluated in 31 interventional procedures in terms of ability to perform the assigned intervention as usual, quality of visual comfort and tolerance using a Likert scale (from 1, as very good to 5, as extremely poor). The mean rating for ability to perform the assigned intervention as usual was 1.7±0.8 (SD) (range: 1–4). The mean visual tolerance rating was 1.6±0.7 (SD) (range: 1–4). The mean tolerability rating was 1.4±0.7 (SD) (range: 1–3). The 3D-printed protective face shield is well accepted in various interventions. It may become an additional option for protection of interventional radiologists.
