摘　　要：目的探讨超声造影在评估经颈静脉肝内门体静脉内支架分流术(TIPSS)后支架管功能中的应用价值。方法选取在本院随访;临床拟诊TIPSS术后支架管功能障碍的105例患者作为观察对象。所有患者行常规超声以及超声造影检查,以同期增强CT结合数字减影血管造影(DSA)结果作为“金标准”作比较分析。结果增强CT结合DSA证实105例患者中,支架管功能障碍41例(闭塞7例,狭窄34例),支架管通畅64例。常规超声诊断支架管功能障碍的敏感度、特异度、准确度分别为70.73%、75.00%、73.33%;超声造影诊断支架管功能障碍的敏感度、特异度、准确度分别为90.24%、95.31%、93.33%;超声造影诊断支架管功能障碍的敏感度、特异度、准确度明显高于常规超声,差异有统计学意义(P<0.05)。结论超声造影能有效监测TIPSS术后支架管功能状态,有利于进一步提高支架管功能障碍的诊断准确性。Objective To investigate the value of contrast-enhanced ultrasonography(CEUS)in the evaluation of stent function after transjugular intrahepatic portosystem stent shunt(TIPSS)。Methods 105 patients with clinical diagnosis of stent dysfunction after TIPSS were selected as the objects.AIll patients underwent conventional ultrasound and CEUS.At the same time the results of enhanced CT and DSA were used as the"gold standard"for comparative analysis.Results The enhanced CT confirmed:41 cases had stent dysfunction(7 cases were occlusive,34 cases were narrow),64 cases had stent patency.The sensitivity,specificity and accuracy of conventional ultrasound in the diagnosis of stent dysfunction were 70.73%,75.00%,and 73.33%respectively.The sensitivity,specificity and accuracy of CEUS in the diagnosis of stent dysfunction were 90.24%,95.31%,and 93.33%respectively.The sensitivity,specificity and accuracy of CEUS in the diagnosis of stent dysfunction were significantly higher than those of conventional ultrasound(P<0.05)。Conclusion Contrast-enhanced ultrasound can effectively monitor the functional status of stent after TIPSS,and improve the diagnostic accuracy of stent dysfunction.
