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
It does not identify the specific cause of the bleeding
Embolization is not possible
Vasopressin infusion is not possible
Transient ischemic attacks
