摘要 目的探讨经食管超声心动图在体外循环下心脏瓣膜置换术中的应用效果,为提高疗效作参考。方法选取2017年4月至2018年5月郑州市第七人民医院收治的40例接受体外循环下心脏瓣膜置换手术患者作为观察对象,在患者术前、术中与术后均进行经试管超声心动图检查,并且在术前进行经胸部超声心动图检查。观察术前经胸部与经食管超声心动图剪叉测量所获得主动脉环内径以及钙化检出几率,对比术前、术后心脏瓣膜与心脏功能指标变化情况。结果体外循环下心脏瓣膜置换手术经胸部超声心动图测量主动脉瓣环内径为(10.60±1.20) mm和钙化检出几率为50.00%,手术病理检查结果发现主动脉瓣内径为(14.80±1.00) mm、钙化检出率为90.00%。经胸部超声心动图测量主动脉瓣内径、钙化率均低于手术病理性结果,差异有统计意义(P<0.05)。经食管超声心动图检查与手术病理检查结果比较,经食管超声检查发现主动脉瓣内径平均为(14.50±0.92) mm、钙化检出率为85.00%,数据差异不明显(P>0.05)。经食管超声心动图检查结果与经胸部超声心动图检查结果比较,差异有统计意义(P<0.05)。结论在体外循环下心脏的瓣膜置换术中,采取经食管超声心动图检查,能够准确指导瓣膜置换与手术方式选择,从而降低并发症的发生率,提高手术成功率。
