Abstract
Objective: The characteristics of liver injuries treated using interventional radiology (IVR) were examined. Subjects and Methods: The characteristics of cases with liver injuries that were treated at this hospital using transcatheter arterial embolization (TAE) for acute-phase bleeding and IVR for late-phase complications between April 1, 2007, and September 30, 2012, were retrospectively reviewed. Results: Of the 43 patients with liver injuries who were treated during the study period, 1, 16, 2, 20 and 4 patients had trauma grades of Ⅰa, Ⅰb, Ⅱ, Ⅲa, and Ⅲb, respectively. Nine patients underwent TAE for the control of acute-phase bleeding. One patient with unstable hemodynamics after TAE underwent surgery for a concurrent inferior vena cava injury. Death during the acute phase occurred in 2 patients whose probability of survival was less than 0.5. As for the late-phase complications, ultrasound-guided percutaneous drainage was performed in 2 patients with biloma, surgery was performed after ultrasound-guided percutaneous drainage in 2 patients with bile leakage, percutaneous drainage was performed in 1 patient with a hepatic abscess, and TAE was performed in 1 patient with a pseudoaneurysm. Conclusion: IVR for the treatment of liver injuries was effective for controlling acute-phase arterial bleeding in patients with a stable hemodynamic status and for the treatment of late-phase complications such as bilomas, hepatic abscesses, and pseudoaneurysms.
