Spontaneous celiacomesenteric trunk dissection: Case report.

Introduction: The celiacomesenteric trunk (CMT) is one of the most striking among the different variations of the normal vascularisation of the gastro-intestinal tract. It is often accidentally discovered during autoptical dissections, angiography or abdominal computed tomography (CT).

Case Presentation: A 27-year-old man was admitted to emergency for an acute abdominal pain. For his critical condition, the patient was immediately brought to the operating room. A extensive intestinal necrosis was found. Post-operator CT discovered a common CMT that is complicated by extended thrombosis. Despite all resuscitation measures, the patient died of septic shock two days later. An autopsy was performed showed that the main cause of intestinal ischemia was related to dissection of a common CMT.

Discussion: A CMT is a highly unusual variation in humans. It is usually asymptomatic and may be discovered incidentally during vascular surgery, radiologic imaging, or cadaver's dissection. Lesion of this entity can lead to serious gastrointestinal complications including necrosis. Different classifications are proposed in the literature.

Conclusion: As it is associated with the risk of mesenteric ischaemia, CMT should be kept in mind as a differential diagnosis for cases of recurrent non-specific abdominal pain.
