[Treatment of iliac artery stenosis and obliteration by transluminal angioplasty].
OBJECTIVE
Percutaneous transluminal angioplasty (PTA) has an established and valuable role in the treatment of iliac stenoses and occlusions. The use of stents may improve the results of PTA. The aim of this study is to report our surgical experience of iliac angioplasty over the past 5 years.


METHODS
From January 1993 to October 1997, 201 iliac PTA were performed in 175 patients, at the level of the common iliac artery (n = 111) and external iliac artery (n = 90). In 26 cases, two iliac lesions were treated simultaneously. There were 188 stenoses and 13 chronic occlusions. During PTA, 55 stents were used, because of unsatisfactory results (dissection, residual stenosis) or in case of total occlusion, in the common iliac artery in 35 cases and in the external iliac artery in 20 cases. In 15 cases (8.6%), a femoro-popliteal bypass was associated to the iliac PTA, because of multilevel occlusive disease.


RESULTS
There were no early deaths. There were seven initial failures. The initial success rate was 96%. The clinical follow-up has been achieved in 163 patients, (range: 3 to 48 months, mean: 28 months). The primary patency rates were 84%, 79% and 63% respectively at 1, 2, and 4 years. The secondary patency rates were 87%, 85% and 73% respectively at 1, 2, and 4 years.
