Endovascular treatment for unilateral chronic total occlusions of the iliac artery categorized as TASC II type D lesions.
OBJECTIVE
To compare the results of endovascular treatment for unilateral iliac occlusion in types B and D, and confirm its validity for type D.


METHODS
Between 2000 and 2011, 108 patients underwent endovascular treatment for unilateral iliac occlusion. 77 were categorized as type B for occlusion of common iliac artery (CIA) or external iliac artery (EIA) and 31 were categorized as type D for occlusion of both CIA and EIA. The initial success rates, procedure time, penetration time, amount of contrast media used, complication rates, and cumulative primary patency rates were determined and compared between these groups.


RESULTS
Between type D and B groups, the initial success rates were 87.1 % (type D) and 89.6 % (type B) (p = 0.9316). The procedure time was 137.0 ± 55.5 and 97.2 ± 47.2 min (p < 0.05). The penetration time was 49.1 ± 40.6 and 31.6 ± 30.1 min (p < 0.05). The amount of contrast agent used was 193.9 ± 103.1 and 156.5 ± 85.0 ml (p = 0.0722). The complication rates were 6.5 and 3.9 % (p = 0.8491). The cumulative primary patency rates, at 1, 3, and 5 years were 91, 85, and 85 % and 100, 96, and 93 %.


CONCLUSIONS
Endovascular treatment can be indicated for unilateral occlusion of both CIA and EIA categorized as type D.
