title: Subintimal angioplasty of infrapopliteal occlusions in critically ischaemic limbs.
abstract: OBJECTIVE
  To review the outcome of subintimal angioplasty of infrapopliteal artery occlusions in critically ischaemic limbs.
  
  
  METHODS
  Retrospective review.
  
  
  METHODS
  Twenty-eight consecutive limbs with critical ischaemia that had undergone subintimal angioplasty of infrapopliteal occlusions.
  
  
  RESULTS
  There were 32 infrapopliteal artery occlusions in 28 critically ischaemic limbs in 27 patients. The median (range) patient age was 81 (48-88) years. Seventeen limbs (61%) were ulcerated, seven (25%) were gangrenous and four (14%) had rest pain only. Twenty-five (89%) procedures were to a single calf vessel, and three (11%) procedures were to multiple calf vessels. The median (range) length of the occlusions was 7 (2-30) cm. The initial technical success rate was 27/32 (84%). There were three minor complications--one groin haematoma, one vessel perforation and one distal embolus. There were no limbs lost as a result of the procedure itself and the 30-day mortality was zero. The 12-month actuarial haemodynamic and symptomatic patencies (including initial failures) were 53% and 56%, respectively. The 12-month limb salvage rate was 85% and patient survival was 81%.
  
  
  CONCLUSIONS
  We conclude that subintimal angioplasty in patients with infrapopliteal artery occlusions and critical ischaemia is safe, effective, and offers a low-risk alternative to distal reconstructive surgery.
