RESUMO
Objective To study the safety and effect of interventional treatment for arteriesclerotic obliterations of iliaco-fermoral artery via radial artery retrospectively.Methods Sixteen cages were treated with interventional procedare via radial artery.The duration of disease was from 3 days to 2 years.All cases presented with rest pain and intermittent claudicating(with distance less than 500 m).Unilateral lesions were found in 9 cases.and bilateral lesions in 7 cases.Iliaco-femoral arteries were obliterated completely in 6 cases.while the other ten cases had arterial stenesis more than 75%.After visualization of obliterative artery.urokinase was administrated consecutively from catheter indweUed in or above thrombus.Transcatheter thrombolysis would be cancelled if the therapeutic effect wag negligible after using umkinase for 72 hours.After thrombolysis.the balloon angioplasty and the stent implantation were performed in the cases with residual stenesis more than 50%. In all of 16 cases,5 caseg underwent continuous intraarterial thrombolysis only.11 cases received balloon angioplasty and/or stent implantation additionally.The ankle/braehial index(ABI)post-treatment and pre-treatment was analyzed.Results The duration of transcatheter thrombolysis was 3.0-15.0 days,averaged(8.4±2.9)days.The obliterative arteries were recanalized in 15 cases.The symptoms of rest pain disappeared in all cases.while intermittent claudicating was still present in 4 cases,but the claudicating distance increased significantly(92.50±60.21 and 625.00±84.26 m for pre-and post-operation respectively).The ABl was 0.63-1.10(0.91±0.12)for post-treatment and 0-4).57(0.32±0.14)for pre-treatment respectively(t=21.73,P＜0.01).During 6-24 months' follow-up,restenosis occurred in 1 case,which was treated successfully once again after halloon angioplasty.There was no serious complication related to the procedure.Conclusion It is safe and effective to apply continuous thrombolysis combined with balloon angioplasty and stent implantation to treat iliacofemoral artery obliteration interventionally via radial arterv.
