Abstract

PURPOSE:

To determine whether the effectiveness of arterial embolization in patients with acute upper gastrointestinal hemorrhage is related to the visualization of contrast medium extravasation at angiography.

MATERIALS AND METHODS:

Transcatheter embolization was performed in 108 patients who experienced acute upper gastrointestinal hemorrhage during a 5-year period. Patient charts were retrospectively reviewed. Thirty-six patients who underwent embolization after angiography demonstrated active contrast medium extravasation from an involved artery. Seventy-two patients underwent embolization in the absence of contrast medium extravasation into a bowel lumen. Embolization technique, requirement for further blood products, need for further surgery, and 30-day mortality were recorded.

RESULTS:

The gastroduodenal artery (GDA) was embolized in 26 of the 36 patients (72%) with extravasation, and the left gastric artery was embolized in 10 (28%). The GDA was embolized in 64 of the 72 patients (89%) without extravasation, and the left gastric artery was embolized in 13 (18%). After embolization, 23 of the 36 patients (64%) with extravasation and 44 of the 72 (61%) without extravasation required additional blood product transfusions. Seven of the 36 patients (19%) with extravasation and 16 of the 72 (22%) without extravasation required subsequent surgery secondary to bleeding. Thirty-day hemorrhage-related mortality was 17% (six of 36 patients) in the positive extravasation group and 22% (16 of 72 patients) in the negative extravasation group. The treatment success rate was 44% (16 of 36 patients) in the positive extravasation group and 44% (32 of 72 patients) in the negative extravasation group.

CONCLUSIONS:

In patients with acute upper gastrointestinal hemorrhage, arterial embolization is equally effective in patients who demonstrate active contrast medium extravasation at angiography as in those who do not show contrast extravasation.
