Abstract: Liver transplant is a complex procedure often complicated by postoperative bleeding events. Early detection of active bleeding is crucial for effective intervention. In this study, we evaluated the efficacy of 384-slice computed tomography angiography in identifying early postoperative active bleeding events after liver transplant. We retrospectively analyzed 53 liver transplant recipients from February 1, 2022, to December 26, 2023. All patients underwent 384-slice computed tomography angiography, capturing arterial, venous, and delayed phases. Results showed that 34.2% of patients experienced bleeding events, with 28.57% of these patients having active bleeding complications. Recurrent bleeding occurred in 3.77% of cases. Computed tomography angiography demonstrated 100% sensitivity, specificity, and positive predictive value in detecting bleeding. Bleeding primarily originated from the perihepatic region and was predominantly arterial. Our findings underscore the value of 384-slice computed tomography angiography in early detection and localization of postoperative bleeding, which enhances patient management and outcomes. Integrating this advanced imaging tool into routine postoperative care can significantly improve intervention accuracy and patient recovery.
