Introduction: Image-guided percutaneous lung biopsy is crucial for histologically characterizing lesions, though it carries risks. Method: This cross-sectional study was conducted on patients undergoing percutaneous lung biopsy in Medellin, Colombia, in 2022. Patients of all ages and sexes with post-procedure control were included. Sociodemographic variables, lesion characteristics, peri-procedural aspects, and complications were collected. Data were analyzed using descriptive statistics, and logistic regression to identify potential factors related to complications. Results: Out of 164 participants, with a median age of 69 years (range: 19-91), 62.2% were women. The most prevalent comorbidity was arterial hypertension (37.2%), followed by chronic obstructive pulmonary disease (17.7%). Most biopsies used an 18 G Trucut needle. Complications occurred in 76.2% of cases, with the most common being pulmonary bleeding (64.6%) and pneumothorax (38.4%). Significant risk factors were emphysema for pneumothorax (OR: 14.4; 95% CI: 2.3-88.7) and long paths to the puncture site for bleeding (OR: 1.05; 95% CI: 1.03-1.09). Conclusions: The high prevalence of complications highlights the need to optimize techniques and peri-procedural management. Small lesions and long paths increase the risk of complications.
