Endovascular treatment of chronic total occlusion of the iliac artery

Introduction: Recent results for intraluminal endovascular interventions for aortoiliac occlusive disease were published with an acceptable long term primary and secondary patencies. Although aortobifemoral bypass is still considered the gold standard for treatment of iliac artery CTOs, the procedure carries a mortality rate of 4.4% and a major complication rate of 12.1%. The aim of the study is to determine which type of patient with iliac CTO and which technique is more suitable for endovascular treatment. Methods: It is a prospective study of 40 patients with symptomatic chronic atherosclerotic lower limb ischemia with isolated (CTO) iliac disease. According to the TASC-II classification, there were 14 patients with TASC type B lesions, 4 patients with TASC type C, and 22 patients with TASC D. Results: Technical success was as 100% and was achieved by completion angiography, and clinical assessment of distal pulsations. Conclusion: Endovascular treatment for iliac artery occlusive disease can be considered an alternative to open surgery for TASC-II B,C,D (CTO) disease, especially in surgically unfit patient, or who refuse surgical intervention.
