Transluminal angioplasty and stenting in treating iliac arterial occlusive disease / 中华普通外科杂志

ABSTRACT

Objective To evaluate therapeutic effect of transluminal angioplasty and stenting on arteriosclerosis related iliac arterial occlusive disease. Methods This retrospective study included a total of 61 cases (76 limbs) with iliac arterial atherosclerotic occlusive disease, grading as TASC A (n =29),B (n = 16), C (n = 11) and D (n = 5). Percutaneous interventional reconstruction and stent implantation were carried out in our hospital from December 2002 to December 2008. Results In 61 patients (76 lesions) 63 stents were implanted successfully with the success rate of 93% (71/76). The rate of clinical improvement was 100% among the patients who had primary technical success. The ankle-branchial index (ABI) improved from an average of 0. 33 ± 0. 17 before intervention to 0. 72 ± 0. 20 on the day following intervention (P < 0. 05). All cases were followed up between 6 month and 60 month. One year patency rate in all treated lesions was 90% (92% in the TASC A and B, 84% in the TASC C and D).Three year patency rate in all was 75% (80% in the TASC A and B, 63% in the TASC C and D). Five year patency rate was 72%. Conclusion There is a tendency towards utilizing transluminal angioplasty and stenting to treat iliac arterial occlusive disease as a therapy instead of traditional vascular surgery.
