Abstract:
PurposeTo investigate CT-guided needle aspiration biopsy in segmental bronchial lesions of central lung cancer., and to provide basis for developing therapeutic schedule.Materials and Methods Fifty-five cases of suspected central lung cancer with segmental bronchial lesions were selected. All patients underwent CT-guided needle aspiration biopsy. The puncture complications and the effect of different position and direction of the puncture needle on complications were observed.Results All 55 patients were punctured successfully in one time. Satisfactory biopsy specimens were collected in all patients. Pathological diagnosis rate was 90.91% (50/55). Operative pathology or post-puncture follow-up confirmed the central lung cancer with segmental bronchial lesions in 40 cases with positive rate of 72.73% (40/55), and the negative rate was 18.18% (10/55). As for puncture complications, the needle tract bleeding was seen in 19 cases (34.55%), and some pneumothorax in 4 cases (7.27%). There was statistic difference between the two complications (χ2=6.03,P<0.01). The complications of prone and supine position had no statistical difference (P>0.05). Incidence of complications decreased with performance angle by the order of vertical puncture, horizontal puncture, and 45 degrees puncture. There was statistic difference (χ2=3.68,P<0.05).Conclusion CT-guided percutaneous needle aspiration biopsy is accurate in diagnosis of central lung cancer with segmental bronchial lesions. It has no serious complication and is worthy of general clinical application.
