A retrospective analysis of the risk factors associated with systemic air embolism following percutaneous lung biopsy.
EXPERIMENTAL AND THERAPEUTIC MEDICINE(2020)
摘要
In the present study, the risk factors for systemic air embolism as a complication of percutaneous CT-guided lung biopsy were explored. Data from 2,026 percutaneous CT-guided lung biopsy procedures were retrospectively analyzed. All cases were divided into a concurrent air embolism group and a control group, depending on whether air embolism occurred during the puncture process. A systemic air embolism was confirmed when CT values <-200 Hounsfield units were observed in two sequential images. A total of 19 cases (0.9%) of air embolism were detected among the 2,026 patients subjected to percutaneous CT-guided lung biopsy procedures. The most frequently detected embolism site was the left ventricle (89.5%). Only 3 cases (15.8%) were accompanied by obvious clinical symptoms. The results indicated that a puncture location above the level of the left atrium and coughing during the procedure significantly altered the likelihood of embolism developing (P=0.002 and P=0.014 vs. control, respectively). In conclusion, a puncture lesion above the level of the left atrium and coughing during the procedure may be risk factors for air embolism development.
