title: [Percutaneous transluminal angioplasty (PTA) of isolated crural arterial stenoses in critical arterial occlusive disease].
abstract: OBJECTIVE
  Retrospective analysis of the results after infrapopliteal PTA of isolated crural limb artery stenoses in patients with critical crural limb ischaemia.
  
  
  METHODS
  Between 1989 and 1994 70 infrapopliteal dilatations of isolated crural limb artery stenoses in 44 patients (47 PTA procedures) were done with small diameter balloon catheters. 45 patients were stage IV according to Fontaine's classification, two patients were stage III. No patient had a relevant obstruction up to the popliteal artery. Follow up ranged from 1-50 months (mean 13.3 months).
  
  
  RESULTS
  A technical success with a residual stenosis below 30% compared to the original vessel diameter was achieved in 80% of patients (n = 56). The cumulative limb-salvage rate was 76.6% after 6 to 36 months after PTA.
  
  
  RESULTS
  In patients with chronical critical crural limb ischaemia PTA of isolated crural limb artery stenoses is an efficient therapy modality for limb-salvage. In many cases PTA is the last alternative method to amputation surgery if there is no sufficient distal vessel for a bypass.
