Critical assessment of the outcome of XXXX .

OBJECTIVE: To perform a more critical assessment of @entity2994 . SUMMARY BACKGROUND DATA: Graft patency may give an unrealistic impression of the outcome of bypass surgery. METHODS: During a 6-year period, 236 @entity1 undergoing primary vein grafts were entered into the study. An ideal outcome required the @entity1 to have survived 12 months with a patent graft on duplex scanning, no perioperative complication, and no further related open or endovascular surgery or admission. RESULTS: At 12 months, the secondary graft patency rate was 82%; however, only 22% of @entity1 had an ideal outcome. At 1 year, 44 (19%) @entity1 died, 93 (39%) required further ipsilateral and 39 (17%) contralateral intervention, and a total of 108 (46%) were readmitted. An ideal outcome was more likely in @entity1 receiving @entity460 channel blockers, principally because of improved primary patency, and less likely in those with @entity712 requiring @entity1483 , principally because of worse survival in these @entity1 . CONCLUSIONS: Few @entity1 achieve an ideal result after @entity2994 . Outcome may be improved by the use of @entity460 channel blockers. Careful consideration is required before performing revascularization in @entity1 with @entity712 .
