Transarterial embolization with n-butyl cyanoacrylate for the treatment of active abdominopelvic bleeding in the polytraumatized patient

Abstract

Abstract Purpose An increasing number of polytraumatized patient presenting with active abdominal pelvic bleeding (APB) have been treated by endovascular selective embolization. However, reports on evaluate the efficacy, safety and complications caused by this technique have been limited. The aim of this study was to assess the safety and efficacy of embolization of APB using N-butyl cyanoacrylate glue (NBCA). Materials and methods Single center retrospective study, that included consecutive 47 patients presenting with traumatic APB treated by embolization with NBCA between January 2013 and June 2019. The efficacy endpoint was defined as the absence of contrast extravasation immediately after procedure and clinical stabilization in the following 24 h after procedure. Clinical stabilization was defined as no rebleeding after embolization or the need for a surgical approach until the patient is discharged. Safety endpoint were any technical or clinical complications related to the embolization procedure. Results The mean age of patients was 38.6 years (3–81), with a predominance of males (87.2%). The major causal factor of APB being involvement in a car accident, accounting for 68% of cases. Of the 47 cases, 29.8% presented pelvic trauma and the remaining (70.2%) presented abdominal trauma. The efficacy rate was 100%, while no complications related to the procedure were observed. The mortality rate was 14.8% (7/47) due to neurologic decompensation and other clinical causes. Conclusion Endovascular embolization of traumatic abdominopelvic bleedings appear to be a highly safe and effective treatment, while avoiding emergent exploratory open surgeries.
