Abstract:
Objective To evaluate the safety of CT guided percutaneous lung biopsy in the elderly,and to analyze the risk factors for its complications.Methods Totally 204 elderly patients aged ≥65 years underwent transthoracic needle biopsy under CT guidance.Clinical data,complication and its risk factors were analyzed retrospectively.Results The complications included pneumothorax accounting for 15.2% (31/204),hemoptysis 21.6% (44/204),and no mortality was found.Logistic regression analysis showed that needle path ≥5.00 cm,lesion size ≤2.00 cm and emphysema around the lesion were the independent risk factors for postoperative pneumothorax (OR=4.05,2.54 and 3.97,all P<0.05).Meanwhile,the enhancement degree by CT >40 HU,needle path ≥5.00 cm and lesion size ≤2.00 cm were the independent risk factors for postoperative bleeding (OR=2.27,2.82 and 2.33,all P<0.05) in elderly patients undergoing lung biopsy.The sensitivity and specificity for postoperative pneumothorax and bleeding obtained by forecasting equation were 87.1% and 49.1%,54.5% and 80.8% respectively.Conclusions The length of needle path,lesion size and emphysema around the lesion are correlated with pneumothroax,and length of needle path,lesion size and the CT enhancement degree are correlated with bleeding after percutaneous lung biopsy in the elderly.
