Background: Pasteurella multocida-related sepsis can cause purpura fulminans (PF), a rare thrombotic disorder that often presents acutely and is potentially fatal. As a consequence of disseminated intravascular coagulation, this hematological emergency originates from micro-thrombotic occlusion of peripheral blood vessels and resulting circulatory failure. Thus far, no studies have reported the use of venoarterial extracorporeal membrane oxygenation (VA-ECMO) for saving lives in patients with worsening respiratory and circulatory failure. Moreover, the development of non-occlusive mesenteric ischemia after VA-ECMO has not yet been documented. Here, we describe the case of a 52-year-old female patient with PF and non-occlusive mesenteric ischemia due to Pasteurella multocida-related sepsis who received VA-ECMO.
Case presentation: A 52-year-old-female patient presented to the hospital with a week-long fever and worsening cough. Chest radiography findings revealed ground-glass opacity. We made a diagnosis of acute respiratory distress syndrome due to sepsis and initiated ventilatory management. Because respiratory and circulatory parameters were not maintained, VA-ECMO was introduced. After admission, ischemic findings were observed in the periphery of the extremities, and a diagnosis of PF was made. Pasteurella multocida was detected in blood cultures. On day 9, the sepsis was cured with antimicrobial treatment. The patient's respiratory and circulatory status improved, and she was weaned off VA-ECMO. However, on day 16, her stable circulatory system collapsed again, and her abdominal pain worsened. We performed exploratory laparotomy and noted necrosis and perforation of the small intestine. As a result, partial resection of the small intestine was performed.
Conclusion: In this case, VA-ECMO was used to maintain circulatory dynamics during septic shock in a patient with Pasteurella multocida infection who developed PF. Surgery was also performed for complicated ischemic necrosis of the intestinal tract, helping save the patient's life. This development illustrated the importance of paying attention to intestinal ischemia during intensive care.
