Transcatheter arterial embolization for acute gastrointestinal bleeding. a, b Contrast extravasation guided embolization. Selective angiography shows contrast medium extravasation from the jejunal branches of the superior mesenteric artery (black arrow) (a). After microcatheterization guided by contrast extravasation, bleeding was controlled by embolization using microcoils and gelfoam (b). c, d Blind embolization. Angiography before embolization shows no evidence of contrast medium extravasation (c). After microcatheterization guided by clip position (black arrow), the left gastric artery terminating at clip was selectively embolized using microcoils and gelfoam (d)
