Blunt abdominal trauma commonly results in solid organ injuries, with the liver and spleen being most frequently affected. The severity of these injuries varies depending on the mechanism and impact of trauma and is systematically classified by the American Association for the Surgery of Trauma (AAST). Vascular injuries may occur in association with solid organ damage; among these, inferior vena cava (IVC) injury is particularly critical because of its high morbidity and mortality. Most IVC injuries are accompanied by concomitant hepatic, splenic, or renal trauma. Isolated IVC injury without associated solid organ involvement is very rare and presents significant diagnostic and therapeutic challenges. We present a case of blunt trauma abdomen with isolated IVC injury who underwent surgical repair. This case underscores the importance of timely recognition and appropriate management of this rare injury to achieve optimal patient outcomes.
