Iliac artery angioplasty : technique and results

Percutaneous angioplasty is widely used for the treatment of iliac artery occlusive disease. Access to the ipsi-lateral, or less commonly contralateral, common femoral artery is obtained under local anaesthesia; the lesion is crossed with a guidewire and dilated with an angioplasty balloon catheter. This technique yields excellent immediate results with very few complications. Stent placement is used in lesions not amenable to balloon angioplasty, in complications, and recurrences. Evidence suggests that balloon angioplasty is the procedure of choice for iliac artery occlusive lesions. Stent placement should be reserved for angioplasty failures. However, primary stent placement is indicated in total occlusions. Lesion morphology is an important determinant of immediate success and long-term patency. TASC lesions type A and B are best treated with angioplasty and stenting, while TASC lesions type C and D show better results with surgical treatment. The development of new stent designs may expand the indications of the percutaneous treatment.
