Application And Safety Analysis Of CT-guided Percutaneous Lung Biopsy In The Diagnosis Of Lung Space Occupying Lesions

Objective: To investigate the accuracy and safety of percutaneous transthoracic needle biopsy(PTNB)in the diagnosis of lung-occupying lesions with multislice computed tomography(MSCT).Methods: The clinical and pathological data of patients undergoing CT-guided percutaneous biopsy performed at the interventional department of Shengjing Hospital,China Medical University from January 1,2013 to October 31,2017 were collected and retrospectively analyzed.The diagnostic rate in clinical diagnosis and the factors that affect the occurrence of complications.Results: The clinical and pathological data of 209 patients undergoing CT-PTNB were collected in this study.Among them,195 patients were definitely diagnosed after surgery,the diagnostic rate was 93.30%,and 14 cases were unidentifiable in nature,accounting for 6.70%.Postoperatively,there were 87 patients with pneumothorax,hemoptysis,and bleeding in the lungs(including bleeding around the lesions and bleeding through the acanthotomy).The incidence of biopsy was 41.63%.None of the above complications were specifically treated.No serious or even fatal complications occurred.Age> 60 years,lesion size <3cm,depth of needle insertion> 2cm,puncture angle ≦ 50° were risk factors for puncture complications,and the difference was statistically significant(P < 0.05).In addition,there was no significant correlation between the location of the lobe and the location of the lobe and complications.There was no statistically significant difference(P>0.05).Conclusion: CT-PTNB is highly accurate and safe for the diagnosis of lung space-occupying lesions.The age of> 60 years old,the size of the lesion <3cm,the depth of needle insertion> 2cm,and the puncture angle ≦ 50° increase the probability of pneumothorax and pulmonary hemorrhage.Patients with complications did not need special treatment,self-improvement,no infection,severe blood pneumothorax required chest drainage,extension of the puncture needle planting transfer,air embolism caused by severe dyspnea or even other serious complications such as death.Can be widely used in the diagnosis of lung space-occupying lesions(including central lesions).
