Introduction:

acute surgical abdomen in the elderly is characterized by its unusual presentation. The reduction of tissue blood flow due to mesenteric ischemia secondary to acute arterial thrombosis in geriatric patients presents as a non-specific acute abdomen. This aspect increases mortality.

Objective:

to describe a case of segmental ischemia of the cecum secondary to fine-branch thrombosis of the ileocecal artery.

Case report:

94-year-old patient, abdominal pain in the right iliac fossa with positive Blumberg sign, accompanied by nausea and vomiting. Pain suggestive of acute appendicitis; the patient underwent emergency surgery and a segmental ischemia of the cecum in its anterior aspect secondary to ischemia of the ileocecal artery due to thrombosis of the fine-branch of the artery in question is confirmed; right hemicolectomy and ileotransversostomy were performed. The clinical evolution was favorable.

Conclusions:

the clinical chart of acute arterial thrombosis in older adults implies a sequence of signs and symptoms subjective to other diseases; its early diagnosis is difficult due to this particularity.
