简介：目的探讨经胸超声心动图与64排CT心血管成像对评价法洛四联症肺动脉狭窄的应用价值,64排CT是否优于常规超声心动图。方法27例法洛四联症患者术前均经过经胸超声心动图与64排CT心血管成像检查,同时观察肺动脉狭窄情况,再与术中病理进行比较。结果经胸超声心动图诊断肺动脉狭窄、右室流出道狭窄、肺动脉瓣狭窄符合率均高于64排CT心血管造影（χ2值分别为15.06、6.13和5.14）,P值均〈0.05,有统计学意义,而对于肺动脉及其分支的发育情况（χ2值为0.50）,P〉0.05,无统计学意义。结论经胸超声心动图检查对法洛四联症肺动脉狭窄特别是右室流出道狭窄和肺动脉瓣狭窄的评估优于64排CT。

简介：摘要目的探讨应用腓肠神经营养血管皮瓣+Bosworth法跟腱翻转延长+自体植骨修复足跟后区软组织及跟骨跟腱附着部分缺损的足功能恢复。方法2004年2月～2010年9月行腓肠神经营养血管皮瓣+Bosworth法跟腱翻转延长+自体植骨修复足跟后区皮肤软组织及跟腱附着部分跟骨缺损8例，皮瓣面积8cm×4cm～10cm×15cm。于患者髂骨取自体骨，固定修补跟骨缺损部分。Bosworth法翻转延长腱膜并固定跟腱膜于再植骨。结果本组8例皮瓣、跟腱、植骨全部存活，经术后随访，皮瓣均生长较满意，再植骨成活，跟建功能存在。行走功能可。结论腓肠神经营养血管皮瓣修复足跟后区创面具有成功率高,与创面皮肤形态，功能相近的优点，覆盖跟腱及再植骨后令受创组织有良好生长环境。Bosworth法翻转延长跟腱于再植骨手术方法简单，跟腱功能存在，良好地保存了足部的行走功能。
