Popliteal artery local technique in superficial femoral artery antegrade subintimal recanalization

Abstract

Objective To evaluate popliteal artery local technique in superficial femoral artery antegrade subintimal recanalization.Methods From January 2009 to Dec 2011,550 limbs in 476 TASC (Trans-Atlantic Inter-Society Consensus) Ⅱ C/D cases underwent endo-therapy at our department.The success rate、operation time、symptom progress and follow up were analyzed retrospectively.Results In the 550 limbs,62 limbs received popliteal artery local technique directly.There was 9 technical failures.Procedures succeeded in 53 limbs(85.5％ ).The average operation time was (69 ±24) min,(1.8 ±0.6) stents were used and the main covered length was ( 33 ± 6) cm.Symptoms of 46 limbs was improved and unchanged in 6,amputation needed to be done in one limb.One year follow up accomplished for 39 limb.The 6 and 12 months patence rate was 87.1％ and 69.2％.For 488 limbs using traditional approach 378 achieved anti-grade recanalization,the average operation time was ( 89 ± 30) min,average (2.1 ± 0.6) stents were used and the main covered length is (31 ± 13) cm.Symptom in 300 limbs improved.The half and one year patence rate in 292 limbs was 92.1％ and 61.0％.Conclusions The popliteal artery local technique is as effective as with traditional approach and is time saving.
