Emergent embolotherapy of small intestine hemorrhage.

The efficacy of emergent embolotherapy was evaluated in six patients suffering hemorrhage from the small intestine. Hemorrhage was from the jejunum in four patients, from the ileum in one, and from Meckel's diverticulum in one. Superselective embolization of the arcade of the small intestine artery branch was performed in all patients with a coaxial catheter. Embolic materials used were Gelfoam particles alone or Gelfoam particles plus coils in earlier cases and microcoils in recent cases. Complete hemostasis was immediately achieved in all patients, but one patient died of disseminated intravascular coagulation. After stabilization of the patient's condition by hemostasis, elective surgery was performed on three patients suffering small intestine ulcer. Histopathologically, no bowel infarction was noted but mild mucosal inflammation with submucosal edema was found in the jejunum of two patients. We recommend embolization for life-threatening small intestine hemorrhage, preferentially in situations where the blood vessel involved can be superselectively occluded at the nearest level of the arcade of the vasa recta, lest the vasa recta should be occluded.
