Abdominal apoplexy: A rare case of spontaneous middle colic artery rupture with transverse colectomy.

Introduction And Importance: Idiopathic spontaneous intraperitoneal hemorrhage (ISIH) is a rare but potentially fatal entity. The majority of the reported cases of ISIH due to middle colic artery rupture are associated with pseudoaneurysm. Our case is unique in that no pathology could be identified. To our knowledge, this is the third case report in the literature of a spontaneous middle colic artery rupture with no underlying pathology.

Case Presentation: In our report, we present the case of a 27-years old male presenting with a hemoperitoneum due to ruptured middle colic artery with no evidence of pseudoaneurysm or any other pathology. The patient's hemodynamic status deteriorated abruptly requiring a damage control exploratory laparotomy for evacuation of the hemoperitoneum, ligation of the middle colic artery and transverse colectomy. The post-operative course was uneventful afterwards and the patient was discharged a week after presentation with full recovery.

Discussion: Patients with ISIH might exhibit the "double rupture" phenomenon, compromising their hemodynamic stability and necessitating urgent surgical interventions. CTA can be of paramount importance to guide such interventions if the patient's clinical status permits. Angiographic embolization is an acceptable alternative approach in specific situations.

Conclusion: ISIH should be on the differential diagnosis of any young patient presenting to the ED with an acute abdomen, regardless of the identifiable risk factors.
