Abstract
INTRODUCTION: Spinal cord injury (SCI) is a major direct cause of accidental death. Cervical SCI can lead to death in a short time period by neurogenic shock. Prompt vasopressor administration is recommended for patients with SCI accompanied by hypotension (systolic blood pressure < 90 mmHg). We herein present the first fatal case of nonocclusive mesenteric ischemia (NOMI) secondary to cervical SCI in a patient who suddenly died 1 week after an accidental fall. CASE PRESENTATION: A 72-year-old man without medical history of cardiovascular disease suffered tetraplegia with a neurological level at C4 after a fall accident. He was fully conscious with stable respiratory ability, and the systolic blood pressure was maintained at >90 mmHg without vasopressor agents. High fever occurred 7 days after the accident and he died in the next morning. Autopsy revealed segmental intestinal necrosis from the ileum to the ascending colon, without mesenteric embolism, or severe arteriosclerosis. DISCUSSION: This case implies that maintenance of >90-mmHg systolic blood pressure can insufficiently keep the blood flow to prevent NOMI, and the mean arterial blood pressure of >85 mmHg can be more plausible as suggested in the guideline. Monitoring the mean arterial blood pressure in acute SCI is useful not only for neurological recovery but also for the maintenance of vital intestinal perfusion.
