Background. This retrospective study examines the long-term results of percutaneous transluminal angioplasty (PTA) in the treatment of steno-obstructive lesions of iliac arteries. It also compares the results of simple PTA versus PTA with stenting at 24 months.
Methods. Between June 1997 and July 2001, 312 iliac PTA (249 males and 63 females) with and without stenting were performed at our Institute. We studied short-term and long-term patency after a mean follow-up of 24 months, taking into account clinical results, objective examination, duplex ultrasonography at 2, 6, 12 months and annually, and arteriography in doubtful cases or with complications.
Results. There was no significant difference in short-term patency between the 2 types of procedures. After a follow-up of 24 months (3-48 months) the cumulative rate of patency for simple PTA was 58.23%, while it was 78.54% for PTA with stenting, whether or not associated with surgery (intraoperative transluminal angioplasty or ITA).
Conclusions. Data obtained from our series concord with those reported in international literature, which underlines that PTA with stenting is a safer procedure than simple PTA ensuring long-term patency in the treatment of iliac district lesions, especially of the common iliac artery. PTA with stenting can also be used with multiple, long and complex lesions that simple PTA cannot resolve.
