[Penetrating duodenal ulcer as a complication of a hepatic artery port catheter in hepatic metastasis of sigmoid carcinoma].

CASE REPORT: We report a typical complication of hepatic artery infusion therapy (HAI) in a patient with colon cancer metastatic to the liver. One year after the last HAI-therapy the patient presented with upper gastrointestinal bleeding. Endoscopy showed a large duodenic ulcer penetrating into an adjacent hepatic colon cancer metastasis. The hepatic artery catheter was visible at the ground of the duodenic ulcer.

CONCLUSION

Thirty-five percent of patients under HAI-therapy develop gastric/duodenic ulcers. The severity of the HAI complication presented here, however, is quite uncommon.
