title: Early results of retrograde transpopliteal angioplasty of iliofemoral lesions.
abstract: OBJECTIVE
  To assess whether the retrograde transpopliteal approach is a safe, practical and effective alternative to femoral puncture for percutaneous transluminal angioplasty (PTA).
  
  
  METHODS
  Forty PTAs in 38 patients were evaluated. Intentional subintimal recanalization was performed in 13 limbs. Ultrasound evaluation of the popliteal fossa was carried out 30 min and 24 hr postprocedurally in the first 10 patients to exclude local complications. All patients had a follow-up of at least 6 weeks.
  
  
  RESULTS
  The indication for PTA was critical ischemia in seven limbs and disabling claudication in the remainder. Stenoses (single or multiple) were present in 24 and occlusion in 15. The superficial femoral artery (SFA) was the commonest segment affected (36) followed by common femoral artery (CFA) in four and iliac artery in four. Technical success was achieved in 38 of 39 limbs where angioplasty was carried out. In one limb no lesion was found. Immediate complications were distal embolization in two and thrombosis in one. None of these required immediate surgery. There were no puncture site hematomas or popliteal arteriovenous fistulae. Symptomatic patency at 6 weeks was 85%. Further reconstructive surgery was required in three limbs and amputation in two.
  
  
  CONCLUSIONS
  The transpopliteal approach has a high technical success rate and a low complication rate with a potential to develop into an outpatient procedure. It should be considered for flush SFA occlusions or iliac disease with tandem CFA/SFA disease where the contralateral femoral approach is often technically difficult.
