The major disadvantage of mesenteric angiography in the setting of GI bleeding is:
Angiography can be used to diagnose and treat severe bleeding. It can be diagnostic, only when the aerial bleeding rate is at least 0.5 mL/min. The sensitivity is 30% to 50% The specificity is 100%. Advantage It permits therapeutic intra-aerial infusion of vasopressin Transcatheter embolization for hemostasis. Disadvantage: Complications-3% Hematoma formation Femoral aery thrombosis Contrast dye reactions Acute kidney injury Intestinal ischemia Transient ischemic attacks Does not identify the specific cause of bleedin
