[Outpatient primary stent-PTA in a symptomatic internal artery stenosis under protection].

In a 69-year old patient, with a symptomatic ICA stenosis a stent implantation was performed under outpatient conditions. An interdisciplinary consensus was reached that the patient was suitable for outpatient therapy. In accordance with the NASCET criteria, the patient was to be classified to the high-risk group. Within 120 days before the intervention, the following clinical symptoms had occurred: 1 TIA, 2 amaurosis fugax. In the diagnostic angiography a right postbulbar ICA stenosis of 97% was verified. The stent application and subsequent PTA were performed under protection using a filter system. The transfemoral route was always fitted with an endovascular closure system. The neck vessels were followed-up by means of colour coded duplex sonography (CCDS) on days 1, 30, 180 and 360. A contrast-medium intensified MRI was performed on the 5th day post-intervention. The implantation of the stent and PTA were done without any complications. Atheromatous plaque fragments were found in the protection system. A plaque embolism was excluded clinically and in the contrast-medium intensified MRI 5 days after the intervention. After 360 days, no restenosis was found in the CCDS, the ECA was perfused. The method presented is low in complications and shows a high success rate. If patient recruitment is adequate, this intervention can be performed on an outpatient basis.
