Imaging was reviewed for each procedure to identify MWA showing transpleural transgression on CT scans. For these patients, demographics, ablation data, pulmonary complication rate, and predictors of pneumothorax were analyzed.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Results:<\/jats:title>\n<jats:p>A total of 71 consecutive sessions (62.1 \u00b1 11.3 years, 79% of males) of MWA were performed to treat 71 tumors (1.90 \u00b1 0.96 cm) via transpulmonary approach under CT guidance. Technical success was achieved in all cases immediately after the procedure. At 1-month follow-up, 65\/69 (94.2%) patients had no residual disease (two patients were lost to follow-up). Pulmonary complications occurred in 26\/71 (36.6%) sessions, and 15\/26 (57.7%) were minor requiring no intervention. Pneumothorax occurred in 14\/71 (19.7%) sessions, and the rate of major pneumothorax requiring chest tube was 8\/71 (11.3%). Lesions on the left side of the liver (segments I\u2013IV) and intraprocedural probe adjustment were found to be independent predictors of developing major pneumothorax (<jats:italic>P<\/jats:italic> = 0.007 and 0.028, respectively). There were no reported pulmonary complications at the 1-month follow-up.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st4\">\n<jats:title>Conclusion:<\/jats:title>\n<jats:p>CT-guided transpulmonary MWA is safe and effective in treating hepatic malignancies. Although it is associated with the risk of developing pulmonary complications, patients underwent successful ablation of their hepatic malignancies without life-threatening complications and mortality.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/jcis_152_2021","type":"journal-article","created":{"date-parts":[[2022,1,20]],"date-time":"2022-01-20T05:45:08Z","timestamp":1642657508000},"page":"2","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["CT-guided
