摘要 观察对高Wilkins超声积分的风湿性心脏瓣膜病、二尖瓣狭窄病人进行经皮二尖瓣球囊成形术治疗 的效果。方法 21例病人,二尖瓣呈中、重度狭窄,Wilkins超声积分在11分以上,因心肺功能不全不能耐受手术 或不愿意进行瓣膜置换术。扩张的预期值为身高的cm值÷10+9,采用Inoue方法,以小于预期值1-2mm开始多 次扩张,在术中监测左房压和了解心脏杂音变化情况。结果所有病人均顺利进行了经皮二尖瓣球囊成形术。 瓣口面积由术前的0.96cm2x±0.31cm2增加到术后1.58cm2±0.37cm2、P<0.05:左房压由术前的20.3±4.5mmHg下降 为10.4+4.8mmHg、P<0.05。术后心功能明显改善7例,2例无明显变化。术后并发症:经B超证示6例新近出现二 尖瓣返流量和3例二尖瓣返流量增加达中量(42.9%);1例出现右侧视网膜中动脉栓塞(4.8%)。结论 对部分 中、重度二尖瓣狭窄,不能或不愿意接受外科手术治疗的病人,尽管Witkins超声积分不适合球囊成形,但对瓣膜 进行充分的评估,尤其是内外瓣联合的粘连钙化情况,适当放宽手术指征,本着宁缺勿过的原则选择扩张的尺度 进行球囊扩张治疗,达到缓解部分临床症状的目的是安全可行的。
