Diagnostic significance of CT-guided percutaneous needle aspiration biopsy and analysis in complications

  Objective  To analyze diagnostic significance of CT-guided percutaneous needle aspiration biopsy(CT-PTNB)and complications.

  Methods  Fifty-one patients receiving CT-PTNB were selected as research objects. Pathological diagnosis rate and postoperative complication rate of 51 patients were recorded and analyzed.

  Results  Among the 51 patients, 48 cases were confirmed by one time biopsy and 2 cases were confirmed by second time biopsy, with a total diagnosis rate of 98.0%(50/51). Five patients developed pneumothorax after surgery, and the occurrence of pneumothorax was significantly related to affected side emphysema and lesion maximum diameter (P < 0.05). Local hemorrhage in the lung field occurred in 12 cases after surgery, and a small amount of hemoptysis occurred in 2 cases during the operation. The occurrence of bleeding was significantly related to hypertension, lesion maximum diameter and lesion depth (P < 0.05).

  Conclusion  CT-PTNB is of great significance for the diagnosis and treatment of lung diseases, especially tumors, and its complication rate is low.
