This case involves a middle-aged female patient with a history of poor circulation who presented with persistent foot pain. She underwent a cardiac bypass graft and was discharged home after the designated recovery period. A few days later, the patient returned to the emergency room with a sudden onset of groin swelling. An abdominal CT angiogram showed a large groin hematoma, and the patient went into cardiac arrest from severe septic shock. Once stabilized, the patient underwent an exploratory surgery. Intraoperatively, it was discovered that part of the graft had perforated the intestine. The patient still suffers complications as a result of the severe sepsis that resulted. An expert in vascular surgery with extensive experience in these procedures was sought to review the perioperative course of the aortobifemoral bypass and delayed detection of the perforation.
