[Presentation of a new self-expanding vascular spiral stent].
The technical details as well as first clinical results of a newly developed Nitinol stent are presented. The spiral-shaped Nitinol stent was implanted in two patients with complicated peripheral arterial obstruction after bypass surgery. Stent implantation was very exact and technically simple using a special implantation catheter. While one patient is free of symptoms three months after stent implantation, an early obstruction was observed in the other patient one day after the interventional procedure. The specific spiral design allows a simple percutaneous extraction of the stent. A cross-over use of the stent seems principally possible, but limited due to the length of the implantation catheter of 70 cm. Prospective clinical studies are, however, warranted.
