| [ Summary ] | Contrast-enhanced multi-detector row helical computed tomography (MDCT) has been established as a rapid, noninvasive, and accurate diagnostic modality for detecting and localizing sites of bleeding in patients with gastrointestinal (GI) hemorrhaging. With arterial phase MDCT images, active GI bleeding is typically identified as a focal area of high attenuation within the bowel lumen, which represents a collection of contrast material that has been extravasated. The choice of treatment using therapeutic endoscopy and transcatheter intervention for hemodynamically unstable patients with acute GI bleeding will depend on the degree of institutional expertise and whether the bleeding site is localized. Modern transarterial embolization (TAE) should be considered as a viable treatment option for the treatment of GI hemorrhaging. Data has steadily accumulated exhibiting the safety and effectiveness of superselective microcoil embolization. | |
