This study analyzed risk factors for hemorrhagic complications after ultrasound-guided liver biopsies. Age, number of needle passes, platelet count, prothrombin time, and international normalized ratio were associated with post-procedure bleeding. Age under 18 years, low platelet count, and increased needle passes were identified as independent risk factors for bleeding complications.
Purpose: This study was performed to analyze the risk factors for hemorrhagic complications after ultrasound-guided liver biopsies. Patients and Methods: In this retrospective study, we reviewed 1193 ultrasound-guided percutaneous liver biopsies performed in our hospital from January 2018 to December 2020. Relevant patient characteristics, indications for biopsy, laboratory findings, biopsy technique, hemorrhagic complications, and pathologic outcomes were collected. Results: We analyzed 834 procedures performed on 807 patients with complete data. The bleeding group comprised 45 patients with post-procedure bleeding, and non-bleeding group comprising the remaining 789 patients. Univariate analysis showed that age (p < 0.001), number of needle passes (p = 0.009), platelet count (p = 0.002), prothrombin time (p < 0.001), and international normalized ratio (p < 0.001) were associated with post-procedure bleeding. Multivariable regression analysis showed that age under 18 years (p < 0.001), low platelet count (p = 0.001), and increased needle passes (p = 0.025) were independent risk factors for bleeding complications. Conclusion: Sex and focal liver lesions did not affect the risk of post-procedure bleeding. The international normalized ratio and prothrombin time were associated with an increased incidence of bleeding; however, they had no predictive value. Age, number of needle passes, and platelet count were identified as reliable predictors of bleeding.
