Abstract
INTRODUCTION: Spontaneous rupture of an intra-abdominal visceral artery is an exceptionally rare and potentially fatal cause of abdominal apoplexy. PRESENTATION OF CASE: We present a case of a 54-year-old hypertensive male who developed hypovolemic shock in our Emergency Department after presenting with abrupt onset of abdominal pain and diarrhea. Intra-operative findings revealed rupture of the superior mesenteric artery with massive hemoperitoneum. The bleeding vessel was ligated and the patient made a full recovery after 3 weeks in the Intensive Care Unit. DISCUSSION: High index of suspicion is necessary for early preoperative diagnosis and must be considered in any patient with a history of hypertension presenting with abrupt abdominal pain, signs of peritoneal irritation and unexplained hypovolemic shock. Immediate resuscitation and prompt surgical control of bleeding is paramount in patient prognosis. CONCLUSION: The seemingly unpredictable nature of abdominal apoplexy must be noted, a precipitating cause in most cases is untraceable and early diagnosis relies solely on awareness of the condition.
