Complementary roles of interventional radiology and therapeutic endoscopy in gastroenterology

Figure 5 During interventional angiography, contrast extravasation is visualized into the colon via a distal branch artery from the internal iliac artery (white arrow). The culprit vessel was occluded by spasm or dissection at the ostium with no residual active bleeding. During follow-up lower endoscopy, an endoscopic image showed no active bleeding with discrete large sized clean based ulcers, consistent with ischemic colitis.
