Iatrogenic Marginal Artery Dissection during Superselective Microcoil Embolization for Colonic Bleeding

Superselective embolization has become the primary endovascular treatment of choice for lower gastrointestinal hemorrhage refractory to medical management. Untoward events, particularly ischemic complications, are rare with this technique. To my knowledge, iatrogenic marginal artery dissection has not been reported.
