[Results of angiographic follow-up of percutaneous stent implantation in the pelvic arteries with a comparison between Wall and Palmaz stents].

51 occlusions of iliac arteries and 67 stenoses have been treated, including 22 patients with bilateral lesions. Indications for stent implantations were: vascular occlusions (51), restenosis following previous PTA (22) and immediate unsatisfactory results or extensive dissection after PTA (45). Successful placement of a stent was achieved in 116 out of 118 attempts. Period of observation averaged 16 months (3-36 months). Stent occlusion was observed in 8 cases. There was mild intima hyperplasia in 25 patients and in a further 14 intima hyperplasia exceeded 75%. Patency rate after 36 months was 67%; 74 wall stents and 39 Palmaz stents were patent, a patency rate of 73 and 65% respectively after 24 months.
