Abstract:
Objective To explore the application value of computed tomography (CT)-based three-dimensional digital navigation technology in microwave ablation of lung cancer. Methods A total of 92 patients with lung cancer in our hospital were retrospectively analyzed, and randomized to receive microwave ablation with the three-dimensional digital navigation technology or traditional CT-guided microwave ablation (three-dimensional navigation group and traditional group). The two groups were paired according to tumor location, size (the maximum diameter difference of less than or equal to 2 mm), and microwave ablation conditions, for a total of 46 pairs. The operation time, times of microwave ablation needle puncture, CT dose index, incidence rates of intraoperative complications, and postoperative lesion control were compared between the two groups. Results The operation time [(30.07 ± 6.36) min vs (47.20 ± 9.65) min], times of puncture [(1.72 ± 0.69) times vs (7.13 ± 3.00) times], CT dose index [(11.16 ± 2.20) mGy vs (26.67 ± 8.72) mGy], and incidence of intraoperative complications (10.87% vs 34.78%) in the three-dimensional navigation group were lower than those in the traditional group, and the response rate was higher in the three-dimensional navigation group than in the traditional group (93.48% vs 71.74%) (P < 0.05). Conclusion CT-guided three-dimensional digital navigation technology for microwave ablation of lung cancer makes the operation of interventional puncture more accurate and safe.
