2、架置入。結(jié)果 膽道支架置入成功率100%，2例術(shù)后分別出現(xiàn)膽道及腹腔內(nèi)出血，保守治療控制。術(shù)后14周黃疸消除率87.5%。最短生存時(shí)間2個(gè)月，最長18個(gè)月，中位生存時(shí)間6.8個(gè)月。6例隨訪期間出現(xiàn)膽道再梗阻，其中3例經(jīng)B超引導(dǎo)經(jīng)皮經(jīng)肝膽道(PTCD)外引流+膽道沖洗再通，另3例因腫瘤長入，長期PTCD外引流。結(jié)論 (1)膽道金屬支架減黃效果確切，并能原位恢復(fù)膽道的生理連續(xù)性；(2)超聲介導(dǎo)技術(shù)可提高膽道金屬支架置入成功率；(3)充分有效的膽汁外引流能減少支架置入的相關(guān)并發(fā)癥，也為膽道再梗阻提出了解決的途徑。 【關(guān)鍵詞】  膽道梗阻 支架置入 經(jīng)皮經(jīng)肝 超聲引導(dǎo)

8、近年對(duì)16例膽道惡性梗阻患者實(shí)施了B超引導(dǎo)的經(jīng)皮經(jīng)肝金屬支架置入術(shù)，報(bào)告如下。    1  資料和方法    1.1  臨床資料    多種惡性腫瘤導(dǎo)致膽道梗阻患者16例，男性12例，女性4例，年齡2678歲，臨床上均有不同程度的皮膚、鞏膜黃染及肝功異常，血清總膽紅素明顯升高(104.2583 mol/L)。按梗阻部位：高位梗阻(左右肝管匯合平面及以上)2例，其中肝癌、膽囊癌各1例；中位梗阻(肝總管至膽總管中段平面)2例，其中肝癌、胰腺癌各1例；低位梗阻(膽總管下段及以下)12例。本組

9、患者伴有膽道感染6例，陶土便7例，凝血功能異常8例。    1.2  儀器及材料    日本Aloka SSD680EX彩超機(jī)，探頭頻率3.5 MHz，MP2411B穿刺架。6F多孔導(dǎo)管(帶針芯)，Arrow金屬引導(dǎo)絲，COOK自膨式鎳鈦合金膽道金屬支架(ZIV78086.0)，0.035超滑導(dǎo)絲及球囊擴(kuò)張管。500 mA放射機(jī)(3200HGDAR299,SHIMADZU)。    1.3  方法     2  結(jié)果 

10、0;  2.1  B超引導(dǎo)經(jīng)皮經(jīng)肝支架置入    本組膽道支架置入成功率100%。9例經(jīng)右前支擴(kuò)張膽管穿刺建立經(jīng)皮經(jīng)肝通道，7例經(jīng)左外下支膽管穿刺建立經(jīng)皮經(jīng)肝通道，隨后置入膽道支架。其中1例膽囊癌致肝門膽管梗阻，行右肝膽道支架置入并超聲介導(dǎo)左肝內(nèi)膽管PTCD外引流；1例肝癌壓迫右肝管行右肝管支架置入；另14例中低位膽道梗阻患者膽道金屬支架釋放遵循如下原則：支架中點(diǎn)與狹窄中點(diǎn)重合，支架應(yīng)跨越狹窄兩端1.0 cm以上，胰頭及壺腹腫瘤患者支架置于十二指腸內(nèi)長度23 cm。    2.2  并發(fā)癥    1例支架置入術(shù)后出現(xiàn)膽道出血，表現(xiàn)為PTCD管血性膽汁流出。經(jīng)膽道持續(xù)滴注冰鹽水、去甲腎上腺素和凝血酶混合液，3 d后出血停止，造影示支架通暢，拔除PTCD管。另1例于支架置入后6 h出現(xiàn)血壓下降、脈搏增快和血紅蛋白下降，B超檢查及診斷性腹腔穿刺結(jié)果顯示腹腔內(nèi)出血。其原因可能與術(shù)前血小板減少、凝血功能障礙及機(jī)械性創(chuàng)傷等有關(guān)，經(jīng)保守治療，5 d后病情穩(wěn)定，11 d后平穩(wěn)出院。本組無膽道感染、膽漏、膽道及十二指腸穿孔發(fā)生。  &#
