- Abstract:
- Abstract: Objective To observe and evaluate the clinical value of percutaneous lung biopsy guided by large-aperture CT simulator. Methods The clinical data of 52 patients receiving conventional CT-guided percutaneous lung biopsy in Wuzhou Red Cross Hospital from January 2011 to June 2014 (group A), and those of 116 patients who underwent lung biopsy guided by large-aperture CT simulator from July 2014 to October 2018 (group B) were collected in this study. The diagnostic rates and complication rates of two groups were retrospectively analyzed and compared. Results The biopsy specimens from both groups were sent for pathological examination, and the results showed that there was no significant difference in the diagnosis rate between two groups (P>0.05). The first-attempt success rate for percutaneous lung biopsy in group A and B was 53.4% and 76.7%, respectively, with statistical differences (P<0.05). The complication rates in the two groups were similar, without statistical differences (23.1% vs 27.6%, P>0.05). Conclusion Both of conventional CT-guided percutaneous lung biopsy and percutaneous lung biopsy guided by large-aperture CT simulator are considered to have high diagnostic rate and low incidence of complications, without fatal complications. Moreover, large-aperture CT simulator can realize accurate positioning and fixation with vacuum mould, and is suitable for the examination of obese patients because of its large apertures. Percutaneous lung biopsy guided by large-aperture CT simulator is worthy of popularization.
