[Results of "cross-over implantation of Palmaz-stents" with cross-over sheaths].

PURPOSE: Presentation of technique of cross-over stent implantation of Palmaz stents using a cross-over sheath.

MATERIAL AND

METHODS

Between 1996 and March 1997 72 patients presenting symptoms of peripheral artery disease received 136 Palmaz stents, which were implanted in a cross-over technique with the aid of a cross-over sheath.

RESULTS

As indications for stent implantation occurred: occlusion (n = 14), recoil (n = 11), distinctive calcification (n = 32), recurring stenosis/occlusion (n = 32), perforation (n = 3), dissection (n = 31), and aneurysms (n = 2). The cross-over technique with the aid of a cross-over sheath was successful in all 136 cases. Within the first 24 hours 3 acute reocclusions occurred (all femoral). For stents placed in the iliac artery the primary patency rate was 93.3% at 12 months and for stents placed in the femoral artery 72.0%. Furthermore, this techniques allows for simultaneous stenting of pelvic, femoral or lower leg arteries (n = 17). By using this technique, stenting of the distal external iliacal artery, common femoral artery (CFA) and proximal superficial femoral artery becomes either possible for the first time or easier.

CONCLUSION

If Palmaz stents with a length of 2-7.8 cm should be implanted in the cross-over technique, the use of a cross-over sheath is recommended.
