Purpose:
Evaluation of midterm success and patency rates after placement of Cragg stents in iliac arteries.
Material And Methods:
During a period of 26 months 16 patients, with a total of 19 iliac lesions were treated percutaneously by placement of 20 stents. Indications of stent placement were iliac occlusion in 4 cases and high-grade iliac stenoses in 15 cases. Indication for stent placement in the stenotic lesions were insufficient results following balloon angioplasty in 11 cases and extensive dissection in 4 cases.
Results:
The ankle-brachial index was improved from 0.53 +/- 0.28 to 0.85 +/- 0.26 immediately after the intervention and was 0.80 +/- 0.15 at 16 months follow-up. Cumulative patency rate was 71% after 12 months.
Conclusion:
The occlusion and restenosis rates are high. Disadvantages of Cragg stents are low flexibility and a large bore introducer system. The radiopacity of the Cragg stent is advantageous for fluoroscopic positioning.
