ENDOVASCULAR TREATMENT OF INFRARENAL AORT IC-ANEURYSM WITH THE STENTOR SYSTEM - PRELIMINARY-RESULTS

The Stenter is a thermal memory Nitinol frame covered by an external p ermeable polyester fabric. The Mialhe Stenter bifurcation which is mat ted into the infra renal aorta is designed for the treatment of AAA ex tended to the bifurcation and the iliac arteries. The bifurcated devic e is comprised of two separately introduced segments: - the aortic par t with a fixed iliac limb loaded into a 18 F delivery system is introd uced into the common femoral artery by a cut down approach, - the cont ralateral iliac leg loaded into a 10 F introducer is inserted percutan eously. This preliminary serie involves 84 Stenter procedures: 14 stra igth, 2 tapered, 21 single bifurcated and 50 bifurcated and extended d evices. The per and post operative surgical complications are reported : 4 peripheral emboli, 1 partial left colon ischemia, 2 hematomas and 1 local infection at the access site. Post operative angio and CT sca n are necessary to identify the remaining leakages and their origin. I n this serie two AAA remain injected because of a proximal leakage by mismatch which has to be treated by implanting a cuff. These prelimina ry results demonstrate the accuracy of the proximal positioning, the a daptability of the device according to the anatomical situation and it s ability to be extended. A long term follow-up study is necessary to prove the long term effectiveness of the endovascular exclusion of AAA and to improve the selection criteria.
