RESUMEN
Objective To investigate the security and effect of endovascular stents placement in treating atherosclerotic stenosis of the iliac arteries.Methods 15 cases with iliac arterial stenosis caused by atherosclerosis were treated by a big amount of thrombolysis in combination with iliac arterial stent placement.The length of lesions was from 4.3 cm to 9.5 cm(mean of 6.7 cm),the claudicant distance was from 100 m to 300 m(mean of 185 m).Clinical follow-up included CT angiography,color Doppler sonography and clinical evaluation with the ankle-brachial index(ABI).Results Eighteen stents were placed in 18 limbs of 15 patients.The technical successful rate was 100%.The clinical symptoms(claudication or the rest pain)were improved,and ABI increased from 0.25?0.18 to 0.85?0.15 after stent implantation in all cases.All the patients were followed up for 3~47 months,one patient was death during the follow-up periods because of brain stem ischemic stroke.All patients maintained uninterrupted stent patency until the final follow-up.Conclusion Iliac arterial stent placement is a safe treatment with favorable long term patency for treating arterial stenosis caused by atherosclerosis.
