Nonocclusive mesenteric ischemia secondary to spinal cord injury: an autopsy case.

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 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.
