摘要 目的比较小外径球囊与经典保护导丝,在冠脉分叉病变介入治疗中对分支开口保护效果。方法比较30例冠脉分叉病变,随机分为两组,A组(15例)放置保护导丝于分支内,完成主支内球囊预扩张、支架植入,观察分支血流情况;B组(15例)完成主支内球囊扩张后,放置小外径球囊于分支开口附近,于主支支架扩张同时低压力扩张分支球囊,支架植入后观察分支开口血流情况。通过两组间分支血流相应评分,比较分支开口保护情况。结果 A组有3例分支闭塞,7例血流减少,5例血流同于术前,0例血流改善,总计分17分。B组有0例分支闭塞,1例血流减少,5例血流同于术前,9例血流改善,总计分38分。两组比较差异有统计学意义(P<0.05)。结论采用小球囊保护分支血管,较经典导丝保护后的分支血流情况进一步得到改善,提高手术效果,减少后续处理的难度。
