Internal carotid stent implantation with angioscopic control.
Stent implantation is a method, which is being used more and more often, mainly in the field of peripheral arteries, but coronary stent implantation is also well-known. The authors apply this procedure for patients, who besides the carotid bifurcation stenosis also suffer from the internal carotid stenosis in a longer section of the artery. The indication are as follows: 1 in the case of internal carotid stenosis in a longer section we assure the flow with the help of carotid thrombendarterectomy and slove the run-off with balloon catheter dilatation and stent implantation. 2. in the case of a stenosis in a short section we use stent implantation to avoid dissection of the intima. With each intervention we perform the carotid bifurcation thrombendarterectomy. The authors made the first intervention 15 months ago, since then we have performed 17 stent implantations. One of the 17 patients developed a temporary stroke (TIA). This is a new method, further cases are needed for long-term experiences. Intervention under eye-control can be carried out with more confidence. As regards to the post-operative medicinal treatment, the administration of thrombocyte aggregation-blockers or heparinoid preparation (e.g.: PPS-SP 54) after the stent implantation has become a routine therapy. Summarized the foregoing, these cases constitute about 10-15% of all carotid operations, therefore the authors would like to make it clear, that this is not a routine method, but a possibility, strictly respecting the above-mentioned indications.
