Immediate occlusion of in situ saphenous vein bypass grafts: a survey of 329 reconstructions.
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.
