Abstract

Intestinal necrosis represents a catastrophic sequela of acute mesenteric ischemia (AMI), frequently culminating in significant morbidity and mortality. The clinical presentation of AMI is often insidious and non-specific, which contributes to diagnostic delays and subsequently worsens patient outcomes. We present the case of a 60-year-old male who was admitted with abrupt-onset, severe abdominal pain. The clinical course rapidly deteriorated to septic shock. Computed tomography suggested bowel necrosis secondary to acute mesenteric arterial occlusion. Intraoperative exploration identified approximately 1.2 meters of necrotic small intestine, situated 60 cm distal to the ligament of Treitz. The patient underwent segmental resection of the affected bowel with primary anastomosis, received postoperative prophylactic anticoagulation with Lovenox at 12 hours, and achieved an uneventful recovery, being discharged on postoperative day 7. This case report underscores the critical importance of early diagnosis and prompt surgical intervention in improving outcomes for a rare, life-threatening condition
