Successful stent therapy does not seem to depend on the type of stent used but rather on lesion type, lesion length, and other predisposing factors.

The results of stent therapy of residual popliteal stenosis after PTA are encouraging and warrant further investigation.

DXM-coated stents reduce neointimal hyperplasia in dogs when compared with non-coated stents.

The function and safety of a percutaneously implantable catheter-port system were studied in 44 patients with different diseases (32 patients with malignant disease, 11 with peripheral arterial disease, and one with recurrent asthmatic attacks). Most patients required repeated local-regional arterial infusion. Infection (two patients) and catheter-related complications (10 patients) were observed during the follow-up period (maximum length of follow-up, 542 days; mean, 177 days). Port migration or leakage did not occur. The data suggest that this new catheter-port system is safe and easy to handle.

The authors implanted a duodenal stent in a woman with a high-grade duodenal stenosis due to inoperable tumor compression. A flexible self-expanding knitted nitinol stent that conformed to the shape of the duodenum was introduced orally to keep the duodenal passage patent. After stent implantation, repeated vomiting stopped and the patient was able to eat and drink. This technique resolved the patient's duodenal stenosis.
