Stenting for localised arterial stenoses in the aorto-iliac segment.
OBJECTIVE
to determine complications and patency following angioplasty (PTA) and stenting of aorto-iliac stenoses.


METHODS
District General Hospital in U.K.


METHODS
prospective observational study.


METHODS
between December 1994 and June 2000, 50 patients (38 men), median age 64 (41-89) years underwent aorto-iliac stenting. A total of 61 stents were placed. Indications were intermittent claudication in 38 and rest pain, ulceration or gangrene in 12. Sites stented were aorta 11, common iliac artery 32, external iliac artery 14, common and external iliac arteries two. Bilateral iliac procedures were carried out in nine. Two stents were used to correct residual stenoses after aortic stenting. Some 11 recurrent stenoses were treated. The other reasons for stenting were residual stenoses greater than 30% after PTA, tight calcified stenoses or when a stenosed iliac artery was being used as a donor prior to crossover or femoropopliteal bypass.


RESULTS
two immediate technical failures occurred due to malposition. Residual stenoses were corrected by PTA. Two further patients sustained minor complications. None of the aortic stents occluded through two required secondary procedures. Primary-assisted patency was thus 100% at three years. Primary patency following iliac stenting for claudication and critical ischaemia were 97% and 86% at three years respectively.


CONCLUSIONS
PTA and stenting of aorto-iliac stenoses can be safely achieved with durable results.
