Purpose: To evaluate the efficacy of metallic stents for palliation of malignant gastro-duodenal stenosis., Materials and Methods: Twenty-three patients aged from 36 to 88 years old presented with nausea, vomiting and weight loss due to duodenal (n = 16) or antro-pyloric (n = 7) malignant stenosis and underwent placement of 37 Wallstents (1 to 3 per patient) under fluoroscopic guidance., Results: After initial stent placement 17 patients had normal food intake. One patient was able to eat fractionated meals. Five patients did not experience any improvement due to the presence of a jejunal stenosis downstream in 2, or insufficient stenosis coverage in 2 and stent migration in 1. Nine of the 18 patients with improvement died without symptoms within 101 +/- 56 days after stent placement and 6 were alive and symptom-free after a mean follow up of 176 +/- 83 days. Three asymptomatic patients were lost to follow up after 3 days, 1 and 2 months, respectively., Conclusions: Metallic stents appear to be a valuable option for the treatment of malignant gastro-duodenal stenoses.

Objective: We evaluated arteriographic findings and endovascular treatments of eight patients who had bleeding iliac artery pseudoaneurysms and who had undergone radiation therapy (3000-6500 rad [30-65 Gy]) and surgery for pelvic malignancies., Conclusion: Angiography revealed contrast media extravasation in 75% of patients who had bleeding iliac artery pseudoaneurysms and failed to show the source of bleeding in 25%. The patients who had positive findings at angiography were all successfully treated percutaneously, although two patients required additional bypass surgery. Among embolic materials, coils and balloons were safe and efficient, whereas cyanoacrylate was unsafe and led to complications in two of three patients. A covered stent, which was not available for most of our patients, was used in one patient and may be an effective means of treating pseudoaneurysms.
