A female patient aged > 80 years, undergoing chemotherapy for rectal cancer, presented with melena and was admitted to our hospital owing to hemorrhagic shock. Following an emergency blood transfusion and rescue endovascular balloon occlusion of the aorta (REBOA), her hemodynamics remained unstable. After consulting with her family, we decided to monitor her condition under REBOA inflation. After 90 min, her hemodynamics improved, and she regained consciousness. Subsequently, following further discussions with the patient and her family, transcatheter arterial embolization (TAE) was performed. During TAE, the REBOA inflation level was adjusted by palpating the dorsal foot artery. The total inflation time, from insertion to the end of TAE, was 260 min. The patient was discharged on the fourth day of hospitalization without further complications.

In this case, circulatory stabilization using partial REBOA allowed us to reaffirm the patient’s willingness to undergo treatment in an oncological emergency setting, leading to a favorable outcome.
