Procedure data
20 cases were treated with the KODEX-EPD system and 20 cases with conventional fluoroscopy. The total ablation time and total operation time in KODEX group were (36.40 ± 6.72 min vs 35.15 ± 6.29 min, P > 0.05) and (64.20 ± 11.82 min vs 66.00 ± 13.18 min, P > 0.05), there was no significant difference between the two groups. The intraoperative fluoroscopy time was (532.30 ± 72.83 s vs 676.25 ± 269.33 s P < 0.05), the intraoperative fluoroscopy dose was (110.00 ± 28.64 mGy vs 144.68 ± 66.66 mGy, P < 0.05), and the intraoperative contrast agent dosage was (71.90 ± 5.97 ml vs 76.05 ± 5.93 ml, P < 0.05)in the KODEX group compared with the routine group (Table Intraoperative related indicators.
