To investigate the related factors leading to postoperative complications of ultrasound-guided percutaneous lung biopsy.

The retrospective study reviewed clinical data of 205 patients who were hospitalized in the General Hospital of Western Theater Command and underwent ultrasound-guided percutaneous biopsy of lung lesions from January 2015 to December 2017. The pathological feature and complication rate of 205 patients after ultrasound-guided percutaneous lung biopsy were analyzed, furthermore, the study also analyzed the related factors which may lead to postoperative complications of ultrasound-guided percutaneous lung biopsy.

All 205 patients were underwent ultrasound-guided percutaneous biopsy of lung lesions, and the data revealed that the complications occurred in 11 patients, including 8 cases of hemorrhage which accounted for 3.9% (8/205), 3 cases of fever which presented as low-grade fever, accounting for1.46% (3/205), beyond that, all patients returned to normal without serious complications after symptomatic treatment. Furthermore, analyzing the related factors leading to bleeding, it was found that there was no significant difference in the rate of bleeding among patients with different gender, age, BMI and lesion types (P>0.05), and the history of smoking also had no significant effect on the rate of bleeding (P>0.05). However, the higher rate of bleeding is more likely to happen to patients with a history of disease (P=0.005) and a smaller diameter of the lesion (P=0.006). In addition, the related factors of fever were statistically analyzed, and the results showed that the gender, age and lesion types had no significant influence on the rate of fever (P>0.05). And the rate of fever has nothing to do with the history of smoking or diseases (P>0.05), but the higher rate of fever is more likely to happen to patients with BMI≥24 or the diameter of the lesion bwtween 3 cm and 6 cm (P<0.05).

The incidence of postoperative complications of ultrasound-guided percutaneous lung biopsy is low (about 5.37%), and the complications mainly including hemorrhage and low-grade fever, furthermore, the bleeding was mainly related to the history of diseases and the diameter of lesion, while the rate of low-grade fever was mainly related to the diameter of lesion and BMI.
