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.
