Abstract

OBJECTIVE:

We wanted to assess the usefulness of rotational angiography after endoscopic marking with a metallic clip in upper gastrointestinal bleeding patients with no extravasation of contrast medium on conventional angiography.

MATERIALS AND METHODS:

In 16 patients (mean age, 59.4 years) with acute bleeding ulcers (13 gastric ulcers, 2 duodenal ulcers, 1 malignant ulcer), a metallic clip was placed via gastroscopy and this had been preceded by routine endoscopic treatment. The metallic clip was placed in the fibrous edge of the ulcer adjacent to the bleeding point. All patients had negative results from their angiographic studies. To localize the bleeding focus, rotational angiography and high pressure angiography as close as possible to the clip were used.

RESULTS:

Of the 16 patients, seven (44%) had positive results after high pressure angiography as close as possible to the clip and they underwent transcatheter arterial embolization (TAE) with microcoils. Nine patients without extravasation of contrast medium underwent TAE with microcoils as close as possible to the clip. The bleeding was stopped initially in all patients after treatment of the feeding artery. Two patients experienced a repeat episode of bleeding two days later. Of the two patients, one had subtle oozing from the ulcer margin and that patient underwent endoscopic treatment. One patient with malignant ulcer died due to disseminated intravascular coagulation one month after embolization. Complete clinical success was achieved in 14 of 16 (88%) patients. Delayed bleeding or major/minor complications were not noted.

CONCLUSION:

Rotational angiography after marking with a metallic clip helps to localize accurately the bleeding focus and thus to embolize the vessel correctly.
