摘要 目的从病理学角度评价晚期逆行肺灌洗在无心跳供体肺移植中的肺保护作用。方法健康杂种雄性犬24只,随机分为A、B两组,每组供体、受体犬各6只。建立犬左肺原位移植模型。A组(对照组)行早期肺动脉灌洗联合早期逆行灌洗;B组(晚期逆行肺灌洗组)行早期肺动脉灌洗加早期逆行灌洗再联合晚期逆行灌洗。受体移植后维持机械通气观察6h。观察移植前供体右肺和移植后6h供体左肺肉眼观察、光镜及电镜下的不同病理特点。结果晚期逆行灌洗使供肺灌洗更均匀,颜色更白;光镜下移植前和移植后6h可见晚期逆行肺灌洗组肺血管内残留的血细胞和微血栓较少,炎症细胞浸润和组织水肿较轻;电镜下移植后6h可见晚期逆行肺灌洗组肺组织细胞超微结构较为完整,破坏较轻。结论晚期逆行灌洗可以更好地清除供肺内的微血栓、炎性细胞,减轻缺血及再灌注损伤。
