| 目的 观察双源CT在经颈静脉肝内门-体分流术(TIPS)后随访中的应用价值。方法 对28例肝硬化门静脉高压合并上消化道出血或大量腹腔积液接受TIPS的患者,于术后1个月内、3个月内、6个月、12个月、18个月、24个月进行双源CT复查,采用MIP、VR等图像后处理技术,判断肝静脉及门静脉间支架位置通畅情况。结果 28例患者中,3例(10.71%)支架内血栓形成,MIP示支架处低密度灶,对比剂自狭窄处流过,VR示支架位置、角度满意,及时行球囊扩张溶栓治疗;1例(3.57%)支架冗长、成角,再次植入支架;24例(85.71%)TIPS术后未出现分流道狭窄或血栓,MIP成像显示支架通畅,内见对比剂通过,VR显示支架位置、角度满意。结论 双源CT血管成像技术具有安全、无创、准确的优点,且同时能对肝实质进行观察,可作为TIPS术后的首选随访手段。 |

| Objective To observe the value of dual-source CT (DSCT) angiography in the follow-up of patients after transjugular intrahepatic portosystemic shunt (TIPS). Methods Totally 28 patients underwent TIPS for liver cirrhosis, portal hypertension with upper gastrointestinal hemorrhage or mass ascites. All patients underwent DSCT examination within 1 month or 3 months, and 6 months, 12 months, 18 months, and 24 months after TIPS. MIP and VR were performed to determine the position and patency of the shunt between the hepatic vein and portal vein. Results Thrombosis was detected inside stent in 3 cases (10.71%), MIP showed low density lesions, contrast agent flowed from stenosis, VR displayed good position and angle of stent. After balloon expansion, patent shunt was obtained again in the above 3 patients. The stent was lengthy and angular in 1 patient (3.57%), who then underwent the secondary stenting. No thrombosis nor stenosis was found in 24 patients (85.71%), among them MIP showed the patent stent and contrast agent, VR displayed the satisfied position and angle of the stents. Conclusion DSCT angiography is safe, non-invasive and accurate, able to display the parenchyma of liver, therefore can be regarded as the first choice for the follow-up of patients after TIPS. |
