title: Immediate occlusion of in situ saphenous vein bypass grafts: a survey of 329 reconstructions.
abstract: OBJECTIVE
  To evaluate the cause of immediate occlusions (those occurring during the first month postoperatively) of infrainguinal reconstruction using in situ saphenous vein.
  
  
  METHODS
  Retrospective clinical study.
  
  
  METHODS
  University hospital, Finland.
  
  
  METHODS
  329 in situ saphenous vein bypasses done during the period 1988-1995.
  
  
  METHODS
  Immediate result, and causes of occlusion during the first month postoperatively.
  
  
  RESULTS
  65 of the reconstructions (20%) failed within 1 month, 46 of which were reoperated on, 25 successfully, giving a 1-month secondary patency of 88% (289/329). The cause of the occlusion was related to the vein graft in 29 (45%) and the result of inadequate run-off in 19 (29%).
  
  
  CONCLUSIONS
  Many immediate occlusions of in situ saphenous vein bypass are graft-related or the result of technical problems, necessitating aggressive intraoperative evaluation.
