Advantages |
Therapeutic interventions can also be performed |
Can be used in hemodynamically unstable patients |
Can localize exact site and cause |
No bowel preparation required |
Disadvantages |
Embolization and vascular access site related side effects |
Ionizing radiation and contrast related side effects |
Cannot detect very slow bleed |
Poor performance in variable arterial anatomy |
Recommendation |
For LGIB, hemodynamically unstable patients: initial modality of choice |
Recurrent/continuous bleeding after post colonoscopic treatment for LGIB |
For UGIB, acutely bleeding patients with negative endoscopy or where endoscopy could not find source (specially hemodynamically unstable patients) |
