Abstract:Study 1: Background: This study assesses the feasibility of a radiation absorbing sterile drape in reducing the operator dose by scattered radiation during peripheral endovascular procedures. Materials and methods: Fourty-nine patients who underwent endovascular peripheral stenting, balloon angioplasty or rotary atherectomy were included. Lead free radiation absorbing sterile drapes (RadpadR , Worldwide Innovations and Technologies Inc, KS, USA) were used during 25 procedures (study group), while 24 procedures were performed without the drapes (control group). Electronic personal dosimeters were placed at chest height of the first and second operators to measure unshielded body dose. DAP-adjusted dose was calculated in order to compensate for differences in baseline characteristics between the control and study groups. Mann-Whitney U testing was used for cumulative dose analysis. A multivariate mixed model analysis was used for per-run dose analysis. Results: tatistical analysis resulted in a median dose reduction of 64% for cumulative dose analysis (p<0.01). A mean reduction of 80% was found in per-run dose analysis (p<0.01). Conclusion Usage of the drape resulted in statistically significant operator dose reduction rates while presenting no significant drawbacks during these procedures. Study 2: The feasibility of applying dual-energy techniques to fluoroscopic imaging was assessed in a second study.
