1、中华器官移植杂志2011年11月第32卷第11期ChinJOrganTransplant,November2011,Vo1.32,No.11·663·磁共振胰胆管成像在成人活体右半供肝术前胆道评估中的应用陈丽华季倩李鹏龚必焱张海明沈文【摘要】目的探讨磁共振胰胆管成像(MRCP)在成人活体右半供肝术前胆道评估中的应用。方法76例活体肝移植供者,均切取右半肝用于移植。脂肪餐后进行术前MRCP检查,比较MRCP胆管分型与术中胆道造影胆管分型的一致性;在MRCP图像上测量右后肝管汇入部距左右肝管汇合部的距离及相应右后肝管的直径,对相应胆管测量长度及直径与术中胆道重建方式进行二分类Logi
2、stic回归分析,并得出术中胆道是否成形的ROC曲线及其长度临界值。结果MRCP胆管分型与术中胆道造影胆管分型的符合率为97.4Y0。MRCP所测右后肝管汇人部距左右肝管汇合部的距离和胆管分型是术中胆道重建方式的重要影响因素,而右后肝管直径对术中胆道重建方式的选择无影响。胆道解剖结构变异或I型胆管(MRCP分型)中右肝管长度≤4.2nlin时,95的供肝胆道断端数多于1支,且95行胆道成形术;Ⅲ、Ⅳ型胆管(MRCP分型)所测胆管长度为3.8mil,是选择胆道成形术的分界点。结论MRCP胆管分型能准确反映胆道解剖结构,MRCP右后肝管汇人部距左右肝管汇合部距离测量值可以指导术中胆道
