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.
Stent implantation offers valuable long-term treatment for atherosclerotic iliac artery disease. Success can be predicted on the basis of risk factors.
We have implanted more than 100 Strecker stents in the iliac and femoral arteries. In iliac arteries, follow-up is available from 8 to 48 months (mean 20 months) and in peripheral arteries, from 8 to 32 months (mean 19 months). In iliac and proximal femoral arteries there was a patency rate of 98% (mean 20 months after stent implantation) whereas in peripheral arteries the patency rate was 70.8% (mean 19 months after stent implantation). Besides careful selection of patients, anticoagulation is very important for successful stenting. Because of the excellent results of stents in iliac vessels there is a wide range of good indications, including primary stenting after recanalization of occlusions. In contrast, stent implantation in peripheral vessels should be restricted to special cases such as acute dissection or reocclusion after successful recanalization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
