Abstract:
We report the case of a 19-year-old woman who experienced delayed hemorrhage 4 h after emergency liver repair for traumatic rupture. Digital subtraction angiography (DSA) confirmed that the source of bleeding was an anatomically variant right inferior phrenic artery (originating from the right renal artery), and the patient subsequently underwent successful hemostasis via transcatheter arterial embolization (TAE). This case reveals the masking effect of hypotension during compensated shock on vascular injuries and highlights the limitations of routine surgical exploration in identifying rare vascular variants. Furthermore, it emphasizes the necessity of a comprehensive management strategy based on preoperative imaging, dynamic intraoperative exploration, and multidisciplinary team (MDT) collaboration.
